Script functions

Simulation variables

Varibles are used to communicate between fields and bodies. Setting a variable in the scripted field and reading it in a controller field for example.

setVar(name,value)
getVar(name)
getSetVar(name,value=0)#shortcut function that allows you to get the current value and set it at the same time.

Inputs

Inputs return a value depending on the state of the key/joystick etc. For example key(“space”) returns 1.0 if the space key is down 0.0 if it is not.

key(name)
joy(name)
joybutton(name)
slider(sname,defaultValue=0.5,min=0.0,max=1.0)

Physics body

These functions change the physics body as described.

magnetic=true/false
nocollision=true/false
solid=true/false
push(direction)
getVelocity()
setVelocity(velocity).

•setVelocity(velocity). 

# setVelocity takes a vector that is the direction the object will 
#be moving and the length of the vector is how fast. It is different 
#from push because it actually sets the objects velocity rather than 
#just try to push it.
onstart{
   setVector([0,0,10]) #set object to moving straight up at speed 10
}

•setVelocity(velocity).

# setVelocity takes a vector that is the direction the object will

#be moving and the length of the vector is how fast. It is different

#from push because it actually sets the objects velocity rather than

#just try to push it.

onstart{

setVector([0,0,10]) #set object to moving straight up at speed 10

}

setLinearDamping(damp)
setAngularDamping(damp)
getTorque()
setTorque(torque).

#setTorque does the same thing as setVelocity but with the objects
#rotation 
onstart{
   setTorque([0,0,10])#spin object around blue axis
}

#setTorque does the same thing as setVelocity but with the objects

#rotation

onstart{

setTorque([0,0,10])#spin object around blue axis

}

destroy()
teleport(pos,recurse=true)
copy(pos=nil,velocity=nil,lifetime=0)
split(bdy=self,recurse=0)
setCamera()

Joints

createJoint(parent,child,type=”ball”,min=0,max=0,accel=0,damp=0,breakingForce=0)
disconnect()
attach(child,breakingForce=0)#shortcut that creates a fixed joint connection to child
connect(child,type=”ball”,min=0,max=0,accel=0,damp=0,breakingForce=0)#shortcut for createJoint that uses the current body as the parent.
lookAt(target,stiff=10.0,damp=10.0)

Utility

playSound(name)#play an embedded sound. See SoundUI.
logLine(str)#put a message on the screen.
frame()#get current frame
group()#get current Sketchup group
camera()#get the Sketchup camera
position()#get the current position of the body
transformation()#get the current transformation of the body.

Version 3.5.6 - January 26, 2015
  - Minor adjustment to the custom drag tool.
  - Improved security for the two SU API adding methods.
  - Resolved more compatibility issues with some prior SP models.
  - Removed some unnecessary Ruby API adder methods. Thanks to ThomThom for finding them.
  - Fixed minor gear joints bug. Thanks to Deskpilot for reporting.

Version 3.5.5 - October 25, 2014
  - Reverted some changes to default shape to keep compatible with prior
    versions. As well fixed a bug created in SP3.5.4 Thanks to faust07 for
    report.

Version 3.5.4 - October 22, 2014
  - Fixed a bug where flipped bodies didn't generate proper collisions.
    Thanks to faust07 for report.

Version 3.5.3 - October 16, 2014
  - Minor fixes and improvements.
  - onTouch position parameter should be multiplied by the world scale.
  - Added MSketchyPhysics3::SketchyPhysicsClient.#getLifetime(grp),
    #getLifeStart(grp), #getLifeEnd(grp), and #getEmitter(grp).

Version 3.5.2 - September 24, 2014
  - Flipped groups should no longer unflip when simulation starts.
  - Scaled groups with convex collisions should no longer fall through other
    bodies.
  - Added MSketchyPhysics3::SP3xBodyContext.#getGlobalCentreOfMass to get
    body centre of mass in global space.
  - Made adjustments to the dialog, error handlers, and the drag tool.

Version 3.5.1 - September 13, 2014
  - Converted all fixnum forces to float to prevent errors.
  - Made new copyBody function compatible with prior scripted models,
    specifically SP3RC1 Artillery by Mr.K.
  - Stabilized shift flipped bodies technique which was added in SP3.5.
  - Fixed a typo where centre of mass of convexhull2 and compound2 would
    remain improper.
  - Inspector should lookup joints in all shapes. Originally it looked up
    joints within the default shape only.
  - Updated homepage link

Version 3.5.0 - September 12, 2014
  - Fixed tagName exception, a small error that would raise in Sketchy UI
    from time to time.
  - Fixed a glitch where Sketchy UI would fail to save if the dialog is
    closed via the UI button.
  - Joint limit inputs shall be able to interpret math operations. You can
    type 100.mm and it will be converted to 3.94 inches automatically or
    cos(60.degrees) and it will be evaluated to 0.50.
  - Attributes to the newton body pointer, group scale, and some other
    unused attributes shall be removed when simulation resets. Storing them
    is not essential.
  - Component/group axis are no longer modified. This change improves start
    and reset simulation performance.
  - Rewrote pick and drag tool, which relies its calculations on body centre
    of mass, not group origin as originally intended. The original drag tool
    required group axis be shifted to the bounds center (predefined centre of
    mass). Changing the drag tool was an essential step because first, it no
    longer required moving entity axis to the body centre of mass, second,
    changing centre of mass via the setCentreOfMass function doesn't require
    changing group axis, and third, the new drag tool is quite more flexible
    than the original one. The new drag tool is adapted from the Newton
    Dynamics physics utilities.
  - Added Convexhull2 shape, which includes all sub groups in calculation of
    convex collision, and maintains true centre of mass. Original convexhull
    picks geometry one level deep, but does not gather geometry from groups
    within the group. As well it does not have true centre of mass.
    Convexhull2 was added to overcome such problems. Joints and all ignored
    bodies are not included in collision calculation.
  - Added Compound2 shape, which includes all sub groups in calculation of
    compound collision, and maintains true centre of mass. Joints and all
    ignored bodies are not included in collision calculation. Enable show
    collision option to see the differences between Default and Compound2
    shape.
  - Added Staticmesh2 shape, which includes all faces of sub groups in
    calculation of tree collision. Joints and all ignored groups are not
    processed in part of the collision. Original staticmesh gathers faces
    one level deep within the group, but does not search through groups
    inside the main group; that's why staticmesh2 was added.
  - MSketchyPhysics3::SP3xBodyContext.#getCentreOfMass should extract world
    scale.
  - Added MSketchyPhysics3::SP3xBodyContext.#setCentreOfMass(centre)
  - Added MSketchyPhysics3::SP3xBodyContext.#getVolume - returns body volume
    in cubic inches.
  - Added MSketchyPhysics3::SP3xBodyContext.#getDensity - returns mass ratio
    per cubic inch.
  - Added MSketchyPhysics3::SP3xBodyContext.#getMatrix - returns body
    transformation matrix.
  - Added MSketchyPhysics3::SP3xBodyContext.#setMatrix(matrix) - similar to
    teleport.
  - Added MSketchyPhysics3::SP3xBodyContext.#continuousCollisionEnabled?
  - Added MSketchyPhysics3::SP3xBodyContext.#continuousCollisionEnabled=(v)
    Setting state to true will prevent body from passing other bodies at
    high speeds, although this could alter performance at the same time.
  - Added MSketchyPhysics3::SP3xBodyContext.#solid? to determine whether
    body is collidable.
  - Added MSketchyPhysics3::SP3xBodyContext.#collidable? which is same as
    #.solid?
  - Added MSketchyPhysics3::SP3xBodyContext.#collidable= which is same as
    #.solid=
  - Added MSketchyPhysics3::SP3xBodyContext.#magnetic? to determine whether
    body is magnetic.
  - Added MSketchyPhysics3::SketchyPhysicsClient.#pickAndDragEnabled=(v),
    which is an equivalent to pick_drag_enabled=(v).
  - Added MSketchyPhysics3::SketchyPhysicsClient.#pickAndDragEnabled?, which
    is an equivalent to pick_drag_enabled?
  - Fixed MSketchyPhysics3::SP3xCommonContext.#joy and .#joybutton methods.
    Now, they should work if called from the scripted field too.
  - Added MSketchyPhysics3::SP3xCommonContext.#stopSound(channel)
  - Added MSketchyPhysics3::SP3xCommonContext.#stopAllSounds
  - Added MSketchyPhysics3::SP3xCommonContext.#simulation which returns
    $curPhysicsSimulation. Originally it was accessible from the scripted
    field only. Now, its accessible from the controller fields too.
  - Added MSketchyPhysics3::SP3xSimulationContext.#getFrameRate, which is an
    equivalent to #frame_rate method.
  - Added MSketchyPhysics3::SP3xSimulationContext.#getWorldScale
  - Added MSketchyPhysics3::SP3xSimulationContext.#getGravity, which is an
    equivalent to #gravity method.
  - Added MSketchyPhysics3::SP3xSimulationContext.#setGravity(acceleration).
  - Fixed a bug where staticmesh inside a group would force simulation to
    crash. A staticmesh or compound within the group becomes default shape.
  - Stabilized compatibility for SP3RC1, SP3.1, and SP3.2 scripted models.
    Now, all advanced scripted models created in previous SP versions shall
    work with SP3.5.
  - Added continuous collision checkbox option to the emitter. Enabling this
    will prevent emitted bodies from passing other bodies at high speeds.
    Now, bullets will collide if CC is enabled.
  - Added units of measurement to the joint limits. Thanks to Platinius for
    request.
  - Added scripting reference links to UI for easy reference destination.
  - Fixed a glitch where objects would use 0.2 as default density, not the
    assigned default density.

Version 3.4.1 - September 02, 2014
  - Reverted some changes in SP Replay for compatibility with LightUp and
    Skindigo.
  - Added '(Menu) Plugins > Sketchy Physics > Erase All Attributes' option.

Version 3.4.0 - September 01, 2014
  - Compatibility for Mac OS X. Thanks to Kevin (willeykj) for helping out.
  - Fixed MIDI on new Mac OS X platforms
    https://code.google.com/p/sketchyphysics/issues/detail?id=90
    Thanks to Kevin (willeykj) for providing the fix in the post.
  - Renamed folder back to SketchyPhysics3 for compatibility with prior
    scripted models. You may want to remove original SketchyPhysics folder
    from the Plugins folder.
  - Changed the way errors are handled. All script errors will force
    simulation to reset, displaying a message box with an error. Meanwhile,
    all controller errors will be displayed in the Ruby Console, but keep
    simulation running without breaking next tasks.
  - Reverted some changes to remain compatible with the advanced scripted
    models. I thought to add compatibility files at first, but did not want
    to make it a hard task for scripters to migrate their advanced code to
    3.4. I also added compatibility for SP3x and SP3RC1. Now all scripted
    models from various SP versions shall work in 3.4. Although some
    advanced scripted models created by me will not work because they modify
    way too much. Keep in mind, a lot of scripted models will operate in
    SU 2013 and below only. SU 2013 and lower use Ruby 1.8.x, while SU 2014
    uses Ruby 2.0.0. There were Ruby implementation changes since 1.8.x.
    These include, prohibited use of spaces between method name and the
    parentheses, prohibited use of colons (:) in case-when statement, and
    replaced Hash.#index with Hash.#key. As well, all models that use
    LazyScript will operate in SU 2013 and below only. Some LazyScript
    functions use Ruby DL, which is only available in Ruby 1.8.x categories.
    SP 3.4, on SU 2014, uses Fiddle because DL is deprecated in Ruby 2.0.0.
  - Added Sketchup::Group.#definition and Sketchup::ComponentInstance.#entities
    for compatibility with prior scripted models. These are the only two
    methods SP adds to Sketchup API. These methods shouldn't break any
    plugins, but they may confuse a plugin developer.
  - Included Math into Object for compatibility with prior models. Such
    change shouldn't affect any plugins, but it may confuse the plugin
    developer.
  - Fixed minor controller inconsistencies and errors created while
    rewriting the code in SP 3.3. Thanks to my brother Stas for finding the
    bug at a very last moment before the upload.
  - Fixed compound transformation shift. Thanks to Kris Yokoo and Joseph
    Shawa for report. This is also a bug I introduced in SP 3.3.
  - Fixed export animation in SU2014. Thanks to Werner_Hundt for report.
  - Added start/commit operation to Sketchy Replay for better performance.
  - Added export camera recording to Sketchy Replay. Thanks to faust07 for
    report and Mr.K for writing the original script.
  - Changed abort_operation back to commit_operation as abort_operation
    is unsafe and breaks compatibility.
  - Organized icons
  - Made SketchyPhysicsClient and SketchyReplay compatible with the
    Twilight Render.
  - Added export animation to Kerkythea. You must have have Kerkythea plugin
    installed in order for that feature to work. Thanks to tallbridgeguy for
    request.
  - Migrated from FFI to Fiddle. This reduces folder size, and allows SP to
    operate on Mac OS X.
  - Added MSketchyPhysics3::SP3xBodyContext.#static?
  - Added MSketchyPhysics3::SP3xBodyContext.#static=(state)
  - Added MSketchyPhysics3::SP3xBodyContext.#frozen?
  - Added MSketchyPhysics3::SP3xBodyContext.#frozen=(state)
  - Added MSketchyPhysics3::SP3xBodyContext.#getMass
  - Added MSketchyPhysics3::SP3xBodyContext.#setMass(mass)
  - Added MSketchyPhysics3::SP3xBodyContext.#recalculateMass(density)
  - Added MSketchyPhysics3::SP3xBodyContext.#recalculateMassProperties - This
    method assigns proper centre of mass to the body. SP defines entity
    bounds center as centre of mass, which is incorrect in various cases.
    This function calculates centre of mass using Newton function, which
    presumes the correct centre of mass and moments of inertia.
  - Added MSketchyPhysics3::SP3xBodyContext.#getCentreOfMass - Returns
    centre of mass coordinates relative to the body transformation.
  - Added MSketchyPhysics3::SP3xBodyContext.#this - returns self.
  - Added MSketchyPhysics3::ControllerContext.#lookAt(nil) to destroy the
    lookAt constraint.
  - Added lookAt method to the MSketchyPhysics3::SP3xBodyContext.
  - Added MSketchyPhysics3.getNewtonVersion.
  - Improved MSketchyPhysics3::SP3xBodyContext.#breakit method. Plane size
    shall not be fixed, but shall rely on the group bounds diagonal.
  - Improved MSketchyPhysics3::SP3xBodyContext.split method. Split body
    becomes static. Ideally it should be destroyed, but keeping it ensures
    compatibility.
  - onUntouch event shall be called even if onTouch/onTouching is not
    included.
  - Improved SP Sound UI. Fixed 'Play Sound' button and added 'Stop Sound'
    button. Only WAVE sound format is supported. OGG doesn't seem to work.

Version 3.3.0 - July 20, 2014
  - Compatible in SU2013, and SU2014.
  - Replaced all Sketchup API modifying and adding methods, including
    Sketchup::Group.#copy. Warning, this change prevents many scripted
    models from working, especially those that rely on object entities.
    ComponentInstance doesn't have a .entities method, but its definition
    does. You will have to check before getting entities:
        if ent.is_a?(Sketchup::ComponentInstnace)
            ents = ent.definition.entities
        elsif ent.is_a?(Sketchup::Group)
            ents = ent.entities
        end
    Or use an available function: ents = MSketchyPhysics3.get_entities(ent).
  - Minimized the use of global variables. Warning, this change prevents
    many scripted models from working, especially LazyScript which depends
    on $sketchyphysics_script_version variable. Use MSketchyPhysics::VERSION
    instead. Many more global variables were removed as well; however,
    $curPhysicsSimulation and $sketchyPhysicsToolInstance were not removed,
    as they are quite handy.
  - Improved script error handlers. Simulation will reset properly if an
    error occurs. All detected errors, except those in joint controllers,
    will force simulation to abort. Due to that change many models that were
    uploaded with script errors will no longer work until they r' fixed.
  - Fixed minor inspector dialog errors.
        - Dialog clears when selection clears.
        - Script can handle all sorts of escape characters.
        - No longer throws two error messages.
        - You're no longer required to click on the element to save the
          written script.
  - Rewrote most Ruby files, just to improve the way code looks and fixed
    some minor bugs and inconsistencies. Note: This change could raise more
    errors as I didn't pay much attention to what I did there. Need testers!
  - Used Ruby DL to export functions for Ruby 1.8.x, used FFI to export
    functions for Ruby 2.0.0.
  - Added setSoundPosition2, which properly distributes 3d sound to the
    left and right speakers, and controls volume depending by the specified
    hearing range.
  - Added drawPoints to simulation context, which allows you to draw points
    with style.
  - Added $sketchyPhysicsSimulationTool.cursorPos method - get cursor
    position relative to view origin.
  - Added more virtual key codes, 0-9 keys, semicolons, brackets, etc.
  - Improved SP3xCommonContext.#key method. You may pass key values
    to determine whether the specified key is down. This was added as a
    backup technique if the desired key name is missing, you can pass key
    constant value to get its up/down state.
  - Emit bodies with original density. Previously copied bodies did not
    have same density as the original bodies did. This is fixed now.
  - Temporarily removed check for update as it would recommend downloading
    SP3.2. Use SketchyUcation PluginStore instead.
  - Added simulation.drawExt method, which basically behaves the same as
    simulation.draw, but with more available types. Including, the 'line'
    type yields GL_LINES rather than GL_LINE_STRIP like in the
    simulation.draw method. The simulation.draw method was not replaced
    just to remain compatible.
  - View OpenGL drawn geometry is now included in the bounding box.
  - Added ondraw { |view, bb| } - bb is the Geom::BoundingBox. Use it to add
    3d points to the bounding box, so they don't get clipped. First, add
    points and then draw.
  - Used abort_operation rather than commit_operation to reset simulation.
    This undoes most model changes made during simulation.
  - Created joints will no longer add 'jointBlue' material...
  - Removed MSketchyPhysics3::SketchyPhysicsClient.resetSimulation method.
    Use MSketchyPhysics3::SketchyPhysicsClient.physicsStart to start.
    Use MSketchyPhysics3::SketchyPhysicsClient.physicsReset to reset.
    Use MSketchyPhysics3::SketchyPhysicsClient.physicsTogglePlay to play or
    pause.
    Use MSketchyPhysics3::SketchyPhysicsClient.paused? to determine whether
    simulation is paused.
    Use MSketchyPhysics3::SketchyPhysicsClient.active? to determine whether
    simulation has started.
  - Entity axis are no longer modified. They are modified, but they are set
    back when simulation resets.
  - Clears reference to all big variables at end, so garbage collection
    cleans stuff up.
  - Improved drag tool. Objects won't go to far, and lift object works
    even if camera is looking from the top.
  - Fix the glitch in joint connection tool where cursors didn't update.
  - Added cursor access method.
    $sketchyPhysicsToolInstance.getCursor - returns cursor id.
    $sketchyPhysicsToolInstance.setCursor(id) - id: can be String, Symbol,
    or Fixnum. Available names are select_plus, select_plus_minus, hand, and
    target. For instance, set target cursor when creating FPS games:
        onstart {
            $sketchyPhysicsToolInstance.setCursor(:target)
        }
  - Added toggle pick and drag tool. When creating FPS games you might want
    to disable the drag tool, so player can't pick bodies.
    Use $sketchyPhysicsToolInstance.pick_drag_enabled = state (true or false)
    Use $sketchyPhysicsToolInstance.pick_drag_enabled? to determine whether
    the drag tool is enabled.
    Example:
        onstart {
            $sketchyPhysicsToolInstance.pick_drag_enabled = false
        }
  - Added aliased event names:
    onstart : onStart
    onend : onEnd
    ontick : onTick : onupdate :onUpdate
    onpreframe : onPreFrame : onpreupdate :onPreUpdate
    onpostframe : onPostFrame : onpostupdate :onPostUpdate
    ontouch : onTouch
    ontouching : onTouching
    onuntouch : onUntouch
    ondraw : onDraw
    onclick : onClick
    onunclick : onUnclick
    ondoubleclick : onDoubleClick
    ondrag : onDrag
  - Improved record tool:
    * Objects will move to their original positions when you press the
      rewind button, regardless of when you started the recording.
    * You may toggle recording any-time during simulation.
    * Missing frames will no longer force the object to hide (move! 0).
  - onDrag is called once a frame now (if the mouse is moved).
  - Added onDoubleClick implementation.
  - Added sp_tool which returns MSketchyPhysics3::SketchyPhysicsClient.
  - Added sp_tool_instance which returns $sketchyPhysicsToolInstance.

Version 3.5.6 - January 26, 2015

- Minor adjustment to the custom drag tool.

- Improved security for the two SU API adding methods.

- Resolved more compatibility issues with some prior SP models.

- Removed some unnecessary Ruby API adder methods. Thanks to ThomThom for finding them.

- Fixed minor gear joints bug. Thanks to Deskpilot for reporting.

Version 3.5.5 - October 25, 2014

- Reverted some changes to default shape to keep compatible with prior

versions. As well fixed a bug created in SP3.5.4 Thanks to faust07 for

report.

Version 3.5.4 - October 22, 2014

- Fixed a bug where flipped bodies didn't generate proper collisions.

Thanks to faust07 for report.

Version 3.5.3 - October 16, 2014

- Minor fixes and improvements.

- onTouch position parameter should be multiplied by the world scale.

- Added MSketchyPhysics3::SketchyPhysicsClient.#getLifetime(grp),

#getLifeStart(grp), #getLifeEnd(grp), and #getEmitter(grp).

Version 3.5.2 - September 24, 2014

- Flipped groups should no longer unflip when simulation starts.

- Scaled groups with convex collisions should no longer fall through other

bodies.

- Added MSketchyPhysics3::SP3xBodyContext.#getGlobalCentreOfMass to get

body centre of mass in global space.

- Made adjustments to the dialog, error handlers, and the drag tool.

Version 3.5.1 - September 13, 2014

- Converted all fixnum forces to float to prevent errors.

- Made new copyBody function compatible with prior scripted models,

specifically SP3RC1 Artillery by Mr.K.

- Stabilized shift flipped bodies technique which was added in SP3.5.

- Fixed a typo where centre of mass of convexhull2 and compound2 would

remain improper.

- Inspector should lookup joints in all shapes. Originally it looked up

joints within the default shape only.

- Updated homepage link

Version 3.5.0 - September 12, 2014

- Fixed tagName exception, a small error that would raise in Sketchy UI

from time to time.

- Fixed a glitch where Sketchy UI would fail to save if the dialog is

closed via the UI button.

- Joint limit inputs shall be able to interpret math operations. You can

type 100.mm and it will be converted to 3.94 inches automatically or

cos(60.degrees) and it will be evaluated to 0.50.

- Attributes to the newton body pointer, group scale, and some other

unused attributes shall be removed when simulation resets. Storing them

is not essential.

- Component/group axis are no longer modified. This change improves start

and reset simulation performance.

- Rewrote pick and drag tool, which relies its calculations on body centre

of mass, not group origin as originally intended. The original drag tool

required group axis be shifted to the bounds center (predefined centre of

mass). Changing the drag tool was an essential step because first, it no

longer required moving entity axis to the body centre of mass, second,

changing centre of mass via the setCentreOfMass function doesn't require

changing group axis, and third, the new drag tool is quite more flexible

than the original one. The new drag tool is adapted from the Newton

Dynamics physics utilities.

- Added Convexhull2 shape, which includes all sub groups in calculation of

convex collision, and maintains true centre of mass. Original convexhull

picks geometry one level deep, but does not gather geometry from groups

within the group. As well it does not have true centre of mass.

Convexhull2 was added to overcome such problems. Joints and all ignored

bodies are not included in collision calculation.

- Added Compound2 shape, which includes all sub groups in calculation of

compound collision, and maintains true centre of mass. Joints and all

ignored bodies are not included in collision calculation. Enable show

collision option to see the differences between Default and Compound2

shape.

- Added Staticmesh2 shape, which includes all faces of sub groups in

calculation of tree collision. Joints and all ignored groups are not

processed in part of the collision. Original staticmesh gathers faces

one level deep within the group, but does not search through groups

inside the main group; that's why staticmesh2 was added.

- MSketchyPhysics3::SP3xBodyContext.#getCentreOfMass should extract world

scale.

- Added MSketchyPhysics3::SP3xBodyContext.#setCentreOfMass(centre)

- Added MSketchyPhysics3::SP3xBodyContext.#getVolume - returns body volume

in cubic inches.

- Added MSketchyPhysics3::SP3xBodyContext.#getDensity - returns mass ratio

per cubic inch.

- Added MSketchyPhysics3::SP3xBodyContext.#getMatrix - returns body

transformation matrix.

- Added MSketchyPhysics3::SP3xBodyContext.#setMatrix(matrix) - similar to

teleport.

- Added MSketchyPhysics3::SP3xBodyContext.#continuousCollisionEnabled?

- Added MSketchyPhysics3::SP3xBodyContext.#continuousCollisionEnabled=(v)

Setting state to true will prevent body from passing other bodies at

high speeds, although this could alter performance at the same time.

- Added MSketchyPhysics3::SP3xBodyContext.#solid? to determine whether

body is collidable.

- Added MSketchyPhysics3::SP3xBodyContext.#collidable? which is same as

#.solid?

- Added MSketchyPhysics3::SP3xBodyContext.#collidable= which is same as

#.solid=

- Added MSketchyPhysics3::SP3xBodyContext.#magnetic? to determine whether

body is magnetic.

- Added MSketchyPhysics3::SketchyPhysicsClient.#pickAndDragEnabled=(v),

which is an equivalent to pick_drag_enabled=(v).

- Added MSketchyPhysics3::SketchyPhysicsClient.#pickAndDragEnabled?, which

is an equivalent to pick_drag_enabled?

- Fixed MSketchyPhysics3::SP3xCommonContext.#joy and .#joybutton methods.

Now, they should work if called from the scripted field too.

- Added MSketchyPhysics3::SP3xCommonContext.#stopSound(channel)

- Added MSketchyPhysics3::SP3xCommonContext.#stopAllSounds

- Added MSketchyPhysics3::SP3xCommonContext.#simulation which returns

$curPhysicsSimulation. Originally it was accessible from the scripted

field only. Now, its accessible from the controller fields too.

- Added MSketchyPhysics3::SP3xSimulationContext.#getFrameRate, which is an

equivalent to #frame_rate method.

- Added MSketchyPhysics3::SP3xSimulationContext.#getWorldScale

- Added MSketchyPhysics3::SP3xSimulationContext.#getGravity, which is an

equivalent to #gravity method.

- Added MSketchyPhysics3::SP3xSimulationContext.#setGravity(acceleration).

- Fixed a bug where staticmesh inside a group would force simulation to

crash. A staticmesh or compound within the group becomes default shape.

- Stabilized compatibility for SP3RC1, SP3.1, and SP3.2 scripted models.

Now, all advanced scripted models created in previous SP versions shall

work with SP3.5.

- Added continuous collision checkbox option to the emitter. Enabling this

will prevent emitted bodies from passing other bodies at high speeds.

Now, bullets will collide if CC is enabled.

- Added units of measurement to the joint limits. Thanks to Platinius for

request.

- Added scripting reference links to UI for easy reference destination.

- Fixed a glitch where objects would use 0.2 as default density, not the

assigned default density.

Version 3.4.1 - September 02, 2014

- Reverted some changes in SP Replay for compatibility with LightUp and

Skindigo.

- Added '(Menu) Plugins > Sketchy Physics > Erase All Attributes' option.

Version 3.4.0 - September 01, 2014

- Compatibility for Mac OS X. Thanks to Kevin (willeykj) for helping out.

- Fixed MIDI on new Mac OS X platforms

https://code.google.com/p/sketchyphysics/issues/detail?id=90

Thanks to Kevin (willeykj) for providing the fix in the post.

- Renamed folder back to SketchyPhysics3 for compatibility with prior

scripted models. You may want to remove original SketchyPhysics folder

from the Plugins folder.

- Changed the way errors are handled. All script errors will force

simulation to reset, displaying a message box with an error. Meanwhile,

all controller errors will be displayed in the Ruby Console, but keep

simulation running without breaking next tasks.

- Reverted some changes to remain compatible with the advanced scripted

models. I thought to add compatibility files at first, but did not want

to make it a hard task for scripters to migrate their advanced code to

3.4. I also added compatibility for SP3x and SP3RC1. Now all scripted

models from various SP versions shall work in 3.4. Although some

advanced scripted models created by me will not work because they modify

way too much. Keep in mind, a lot of scripted models will operate in

SU 2013 and below only. SU 2013 and lower use Ruby 1.8.x, while SU 2014

uses Ruby 2.0.0. There were Ruby implementation changes since 1.8.x.

These include, prohibited use of spaces between method name and the

parentheses, prohibited use of colons (:) in case-when statement, and

replaced Hash.#index with Hash.#key. As well, all models that use

LazyScript will operate in SU 2013 and below only. Some LazyScript

functions use Ruby DL, which is only available in Ruby 1.8.x categories.

SP 3.4, on SU 2014, uses Fiddle because DL is deprecated in Ruby 2.0.0.

- Added Sketchup::Group.#definition and Sketchup::ComponentInstance.#entities

for compatibility with prior scripted models. These are the only two

methods SP adds to Sketchup API. These methods shouldn't break any

plugins, but they may confuse a plugin developer.

- Included Math into Object for compatibility with prior models. Such

change shouldn't affect any plugins, but it may confuse the plugin

developer.

- Fixed minor controller inconsistencies and errors created while

rewriting the code in SP 3.3. Thanks to my brother Stas for finding the

bug at a very last moment before the upload.

- Fixed compound transformation shift. Thanks to Kris Yokoo and Joseph

Shawa for report. This is also a bug I introduced in SP 3.3.

- Fixed export animation in SU2014. Thanks to Werner_Hundt for report.

- Added start/commit operation to Sketchy Replay for better performance.

- Added export camera recording to Sketchy Replay. Thanks to faust07 for

report and Mr.K for writing the original script.

- Changed abort_operation back to commit_operation as abort_operation

is unsafe and breaks compatibility.

- Organized icons

- Made SketchyPhysicsClient and SketchyReplay compatible with the

Twilight Render.

- Added export animation to Kerkythea. You must have have Kerkythea plugin

installed in order for that feature to work. Thanks to tallbridgeguy for

request.

- Migrated from FFI to Fiddle. This reduces folder size, and allows SP to

operate on Mac OS X.

- Added MSketchyPhysics3::SP3xBodyContext.#static?

- Added MSketchyPhysics3::SP3xBodyContext.#static=(state)

- Added MSketchyPhysics3::SP3xBodyContext.#frozen?

- Added MSketchyPhysics3::SP3xBodyContext.#frozen=(state)

- Added MSketchyPhysics3::SP3xBodyContext.#getMass

- Added MSketchyPhysics3::SP3xBodyContext.#setMass(mass)

- Added MSketchyPhysics3::SP3xBodyContext.#recalculateMass(density)

- Added MSketchyPhysics3::SP3xBodyContext.#recalculateMassProperties - This

method assigns proper centre of mass to the body. SP defines entity

bounds center as centre of mass, which is incorrect in various cases.

This function calculates centre of mass using Newton function, which

presumes the correct centre of mass and moments of inertia.

- Added MSketchyPhysics3::SP3xBodyContext.#getCentreOfMass - Returns

centre of mass coordinates relative to the body transformation.

- Added MSketchyPhysics3::SP3xBodyContext.#this - returns self.

- Added MSketchyPhysics3::ControllerContext.#lookAt(nil) to destroy the

lookAt constraint.

- Added lookAt method to the MSketchyPhysics3::SP3xBodyContext.

- Added MSketchyPhysics3.getNewtonVersion.

- Improved MSketchyPhysics3::SP3xBodyContext.#breakit method. Plane size

shall not be fixed, but shall rely on the group bounds diagonal.

- Improved MSketchyPhysics3::SP3xBodyContext.split method. Split body

becomes static. Ideally it should be destroyed, but keeping it ensures

compatibility.

- onUntouch event shall be called even if onTouch/onTouching is not

included.

- Improved SP Sound UI. Fixed 'Play Sound' button and added 'Stop Sound'

button. Only WAVE sound format is supported. OGG doesn't seem to work.

Version 3.3.0 - July 20, 2014

- Compatible in SU2013, and SU2014.

- Replaced all Sketchup API modifying and adding methods, including

Sketchup::Group.#copy. Warning, this change prevents many scripted

models from working, especially those that rely on object entities.

ComponentInstance doesn't have a .entities method, but its definition

does. You will have to check before getting entities:

if ent.is_a?(Sketchup::ComponentInstnace)

ents = ent.definition.entities

elsif ent.is_a?(Sketchup::Group)

ents = ent.entities

end

Or use an available function: ents = MSketchyPhysics3.get_entities(ent).

- Minimized the use of global variables. Warning, this change prevents

many scripted models from working, especially LazyScript which depends

on $sketchyphysics_script_version variable. Use MSketchyPhysics::VERSION

instead. Many more global variables were removed as well; however,

$curPhysicsSimulation and $sketchyPhysicsToolInstance were not removed,

as they are quite handy.

- Improved script error handlers. Simulation will reset properly if an

error occurs. All detected errors, except those in joint controllers,

will force simulation to abort. Due to that change many models that were

uploaded with script errors will no longer work until they r' fixed.

- Fixed minor inspector dialog errors.

- Dialog clears when selection clears.

- Script can handle all sorts of escape characters.

- No longer throws two error messages.

- You're no longer required to click on the element to save the

written script.

- Rewrote most Ruby files, just to improve the way code looks and fixed

some minor bugs and inconsistencies. Note: This change could raise more

errors as I didn't pay much attention to what I did there. Need testers!

- Used Ruby DL to export functions for Ruby 1.8.x, used FFI to export

functions for Ruby 2.0.0.

- Added setSoundPosition2, which properly distributes 3d sound to the

left and right speakers, and controls volume depending by the specified

hearing range.

- Added drawPoints to simulation context, which allows you to draw points

with style.

- Added $sketchyPhysicsSimulationTool.cursorPos method - get cursor

position relative to view origin.

- Added more virtual key codes, 0-9 keys, semicolons, brackets, etc.

- Improved SP3xCommonContext.#key method. You may pass key values

to determine whether the specified key is down. This was added as a

backup technique if the desired key name is missing, you can pass key

constant value to get its up/down state.

- Emit bodies with original density. Previously copied bodies did not

have same density as the original bodies did. This is fixed now.

- Temporarily removed check for update as it would recommend downloading

SP3.2. Use SketchyUcation PluginStore instead.

- Added simulation.drawExt method, which basically behaves the same as

simulation.draw, but with more available types. Including, the 'line'

type yields GL_LINES rather than GL_LINE_STRIP like in the

simulation.draw method. The simulation.draw method was not replaced

just to remain compatible.

- View OpenGL drawn geometry is now included in the bounding box.

- Added ondraw { |view, bb| } - bb is the Geom::BoundingBox. Use it to add

3d points to the bounding box, so they don't get clipped. First, add

points and then draw.

- Used abort_operation rather than commit_operation to reset simulation.

This undoes most model changes made during simulation.

- Created joints will no longer add 'jointBlue' material...

- Removed MSketchyPhysics3::SketchyPhysicsClient.resetSimulation method.

Use MSketchyPhysics3::SketchyPhysicsClient.physicsStart to start.

Use MSketchyPhysics3::SketchyPhysicsClient.physicsReset to reset.

Use MSketchyPhysics3::SketchyPhysicsClient.physicsTogglePlay to play or

pause.

Use MSketchyPhysics3::SketchyPhysicsClient.paused? to determine whether

simulation is paused.

Use MSketchyPhysics3::SketchyPhysicsClient.active? to determine whether

simulation has started.

- Entity axis are no longer modified. They are modified, but they are set

back when simulation resets.

- Clears reference to all big variables at end, so garbage collection

cleans stuff up.

- Improved drag tool. Objects won't go to far, and lift object works

even if camera is looking from the top.

- Fix the glitch in joint connection tool where cursors didn't update.

- Added cursor access method.

$sketchyPhysicsToolInstance.getCursor - returns cursor id.

$sketchyPhysicsToolInstance.setCursor(id) - id: can be String, Symbol,

or Fixnum. Available names are select_plus, select_plus_minus, hand, and

target. For instance, set target cursor when creating FPS games:

onstart {

$sketchyPhysicsToolInstance.setCursor(:target)

}

- Added toggle pick and drag tool. When creating FPS games you might want

to disable the drag tool, so player can't pick bodies.

Use $sketchyPhysicsToolInstance.pick_drag_enabled = state (true or false)

Use $sketchyPhysicsToolInstance.pick_drag_enabled? to determine whether

the drag tool is enabled.

Example:

onstart {

$sketchyPhysicsToolInstance.pick_drag_enabled = false

}

- Added aliased event names:

onstart : onStart

onend : onEnd

ontick : onTick : onupdate :onUpdate

onpreframe : onPreFrame : onpreupdate :onPreUpdate

onpostframe : onPostFrame : onpostupdate :onPostUpdate

ontouch : onTouch

ontouching : onTouching

onuntouch : onUntouch

ondraw : onDraw

onclick : onClick

onunclick : onUnclick

ondoubleclick : onDoubleClick

ondrag : onDrag

- Improved record tool:

* Objects will move to their original positions when you press the

rewind button, regardless of when you started the recording.

* You may toggle recording any-time during simulation.

* Missing frames will no longer force the object to hide (move! 0).

- onDrag is called once a frame now (if the mouse is moved).

- Added onDoubleClick implementation.

- Added sp_tool which returns MSketchyPhysics3::SketchyPhysicsClient.

- Added sp_tool_instance which returns $sketchyPhysicsToolInstance.
