pymel.core.effects.rigidSolver

rigidSolver(*args, **kwargs)

This command sets the attributes for the rigid solver In query mode, return type is based on queried flag.

Flags:

Long name (short name)		Argument Types	Properties
autoTolerances (at)		bool
	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)		bool
	Turns bounciness on and off for the an the objects in the simulation. Default value: on
cacheData (cd)		bool
	Turns the cache on fall all rigid bodies in the system. Default value: off
collide (c)		bool
	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)		bool
	Turns the contact data information on/off for all rigid bodies. Default value: off
create (cr)		bool
	Creates a new rigid solver.
current (cu)		bool
	Sets rigid solver as the current solver.
deleteCache (deleteCache)		bool
	Deletes the cache for all rigid bodies in the system.
displayCenterOfMass (dcm)		bool
	Displays the center of mass icon. Default value: on
displayConstraint (dc)		bool
	Displays the constraint vectors. Default value: on
displayVelocity (dv)		bool
	Displays the velocity vectors. Default value: off
dynamics (d)		bool
	Turns dynamics on and off for the an the objects in the simulation. Default value: on
friction (f)		bool
	Turns friction on and off for the an the objects in the simulation. Default value: on
interpenetrate (i)		bool
	Allows the two rigid bodies listed to interpenetrate. Default: interpenetration is off for all bodies.
interpenetrationCheck (ic)		bool
	Checks for interpenetrating rigid bodies in the scene.
name (n)		unicode
rigidBodies (rb)		bool
	Returns a list of rigid bodies in the solver.
rigidBodyCount (rbc)		bool
	Returns the number of rigid bodies in the solver. Flag can have multiple arguments, passed either as a tuple or a list.
showCollision (sc)		bool
	Displays the colliding objects in a different color.
showInterpenetration (si)		bool
	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)		bool
	Turns the rigid solver on or off.
statistics (sta)		bool
	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

Example:

import pymel.core as pm

# Set the playback time range to [1, 100]
pm.playbackOptions(min=1, max=100)
# Result: 1.0 #
# Create a poly cube named "floor"
pm.polyCube(w=10, h=0.10, d=10, sx=10, sy=1, sz=10, ax=(0, 1, 0), name='floor')
# Result: [nt.Transform(u'floor'), nt.PolyCube(u'polyCube1')] #
# Create a poly sphere named "ball", then move it to 0 9 0
pm.polySphere(r=1, sx=20, sy=20, ax=(0, 1, 0), name='ball')
# Result: [nt.Transform(u'ball'), nt.PolySphere(u'polySphere1')] #
pm.move(0, 9.0, 0, r=True)
# Create a new rigid body solver
pm.rigidSolver(create=True, name='rigidSolver1')
# Result: nt.RigidSolver(u'rigidSolver1') #
# Set the floor to passive rigid body
pm.select('floor')
pm.rigidBody(passive=True, solver='rigidSolver1', name='passiveRigidBody')
# Result: nt.RigidBody(u'passiveRigidBody') #
# Set the ball to active rigid body
pm.select('ball')
pm.rigidBody(active=True, solver='rigidSolver1', name='activeRigidBody')
# Result: nt.RigidBody(u'activeRigidBody') #
# Add a gravity field, and connect it to ball
pm.gravity(pos=(0, 0, 0), m=9.8, dx=0, dy=-1, dz=0, name='gravityField')
# Result: nt.GravityField(u'gravityField') #
pm.connectDynamic('activeRigidBody', f='gravityField')
# Result: [u'activeRigidBody'] #
# Play
