Synopsis

rigidSolver([autoTolerances=boolean], [bounciness=boolean], [cacheData=boolean], [collide=boolean], [collisionTolerance=float], [contactData=boolean], [create=boolean], [current=boolean], [deleteCache=boolean], [displayCenterOfMass=boolean], [displayConstraint=boolean], [displayVelocity=boolean], [dynamics=boolean], [friction=boolean], [interpenetrate=boolean], [interpenetrationCheck=boolean], [rigidBodies=boolean], [rigidBodyCount=boolean], [showCollision=boolean], [showInterpenetration=boolean], [solverMethod=int], [startTime=float], [state=boolean], [statistics=boolean], [stepSize=float], [velocityVectorScale=float])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

rigidSolver is undoable, queryable, and editable.

Return value

None

In query mode, return type is based on queried flag.

Flags

Long name (short name)	Argument types	Properties
autoTolerances(at)	boolean
Turns the auto tolerance calculation on and off. The auto tolerances calculation will override the default or user defined values of the step size and collision tolerance value that is calculated based on the objects in the scene. Default: 0 (off)
bounciness(b)	boolean
Turns bounciness on and off for the an the objects in the simulation. Default value: on
cacheData(cd)	boolean
Turns the cache on fall all rigid bodies in the system. Default value: off
collide(c)	boolean
Disallows the interpenetration of the two rigid bodies listed. Default: Collide is on for all bodies.
collisionTolerance(ct)	float
Sets the collision tolerance. This is the error at which two objects are considered to have collided. Range: 0.0005 - 1.000 Default: 0.02
contactData(ctd)	boolean
Turns the contact data information on/off for all rigid bodies. Default value: off
create(cr)	boolean
Creates a new rigid solver.
current(cu)	boolean
Sets rigid solver as the current solver.
deleteCache(deleteCache)	boolean
Deletes the cache for all rigid bodies in the system.
displayCenterOfMass(dcm)	boolean
Displays the center of mass icon. Default value: on
displayConstraint(dc)	boolean
Displays the constraint vectors. Default value: on
displayVelocity(dv)	boolean
Displays the velocity vectors. Default value: off
dynamics(d)	boolean
Turns dynamics on and off for the an the objects in the simulation. Default value: on
friction(f)	boolean
Turns friction on and off for the an the objects in the simulation. Default value: on
interpenetrate(i)	boolean
Allows the two rigid bodies listed to interpenetrate. Default: interpenetration is off for all bodies.
interpenetrationCheck(ic)	boolean
Checks for interpenetrating rigid bodies in the scene.
rigidBodies(rb)	boolean
Returns a list of rigid bodies in the solver.
rigidBodyCount(rbc)	boolean
Returns the number of rigid bodies in the solver.
showCollision(sc)	boolean
Displays the colliding objects in a different color.
showInterpenetration(si)	boolean
Displays the interpenetrating objects in a different color.
solverMethod(sm)	int
Sets the solver method. The choices are 0 | 1 | 2. 0 = Euler (fastest/least acurate), 1 = Runge-Kutta ( slower/more acurate), 2 = adaptive Runge-Kutta (slowest/most acurate). The default is 2 (adaptive Runge-Kutta)
startTime(stt)	float
Sets the start time for the solver.
state(st)	boolean
Turns the rigid solver on or off.
statistics(sta)	boolean
Turns the statistic information on/off for all rigid bodies. Default value: off
stepSize(s)	float
Sets the solvers step size. This is the maximum size of a single step the solver will take at one time. Range: 0.0004 - 0.100 Default: 0.0333
velocityVectorScale(vs)	float
scales the velocity vector display. Default value: 1.0
