pymel.core.effects.rigidBody

rigidBody(*args, **kwargs)

This command creates a rigid body from a polygonal or nurbs surface.

Flags:

Long name (short name)		Argument Types	Properties
active (act)		bool
	Creates a rigid body that is active. An active rigid body accepts and causes collisions and is effected by dynamic fields. This is the default.
angularVelocity (av)		bool
	Current angular velocity of rigid body.
applyForceAt (afa)		unicode
	Determines how forces are applied to the rigid body. The choices are centerOfMass | boundingBox | verticesOrCVs. Default: boundingBox
bounciness (b)		float
	Sets the restitution (or bounciness) of the rigid body. Range: 0.0 - 2.0 Default: 0.6
cache (c)		bool
	Turns caching on (1) or off (0) for the rigid body. Default: off
centerOfMass (com)		float, float, float
	Sets the center of mass (x,y,z) of the rigid body. Default: actual center of mass.
collisions (cl)		bool
	Truns collisions on/off for the rigid body. If the collisions are turned of the rigid body will not collide with any other rigid body. Default: on.
contactCount (cc)		bool
	returns the current contact count for the rigid body.
contactName (cn)		bool
	returns all the rigid body names which are in contact with this shape. One name for each contact will be returned.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
contactPosition (cp)		bool
	returns all the contact position. One position for each contact will be returned.
damping (dp)		float
	Sets the damping value of the rigid body. Range: -2.0 - 2.0 Default: 0.0
deleteCache (dc)		bool
	Deletes the cache (if one exists) of the rigid body.
dynamicFriction (df)		float
	Sets the dynamic friction for the rigid body. Range: 0.0 - 1.0 Default: 0.2
force (f)		bool
	Current force on the rigid body.
ignore (ig)		bool
	Causes the rigid body to be ignored in the rigid solver. Default: off
impulse (i)		float, float, float
	Applies an impulse (instantaneous) force on a rigid body. Default: 0.0 0.0 0.0
impulsePosition (imp)		float, float, float
	The position at which the impulse is applied. Default: the bodies center of mass.
initialAngularVelocity (iav)		float, float, float
	Sets the initial angular velocity of the rigid body. Default: 0.0 0.0 0.0
initialVelocity (iv)		float, float, float
	Sets the initial velocity of the rigid body. Default: 0.0 0.0 0.0
layer (l)		int
	Sets the collision layer of the rigid body. Only rigid bodies in the same collision layer can collide with each other. Range: = 0 Default: 0.
lockCenterOfMass (lcm)		bool
	Locks the center of mass for the rigid body. Default: off
mass (m)		float
	Sets the mass of the rigid body. Range: 0 Default: 1.0
name (n)		unicode
	Assigns the rigid body the given name.
orientation (o)		float, float, float
	Sets the initial orientation (x,y,z) of the rigid body. Default: current orientation.
particleCollision (pc)		bool
	Turns the ability for a rigid body to collide with particles on and off. The particles will exert a force on the rigid body. Default: off
passive (pas)		bool
	Creates a rigid body that is passive. A passive rigid body does not react to collisions but active rigid bodies can collide with it. Dynamic Fields will not effect a passive rigid body. Only passive rigid bodies can be keyframed.
position (p)		float, float, float
	Sets the initial position (x,y,z) of the rigid body. Default: current position.
removeShape (rs)		unicode
solver (slv)		unicode
	The name of the solver which this rigid node is to resided. If the solver does not exists then the rigid body will not be created. If the edit flag is thrown add the solver exists, the rigid body will be moved to that solver.
spinImpulse (si)		float, float, float
	Applies an spin impulse (instantaneous rotational) force on a rigid body. Default: 0.0 0.0 0.0
standInObject (sio)		unicode
	Causes the simulator to use a stand in object for the simulation. The choices are none | cube | sphere. The default is none. Default: none
staticFriction (sf)		float
	Sets the static friction for the rigid body. Range: 0.0 - 1.0 Default: 0.2
tesselationFactor (tf)		int
	Sets the tesselation factor for a rigid body surface. Range: = 10 Default: 200.
velocity (vel)		bool
	Current velocity of rigid body.

Example:

import pymel.core as pm

# Creates a rigid body with a initial velocity of 10 in the x
# direction, a bounciness of 0.5 and a static friction coefficent
# of 0.4.
#
pm.rigidBody( n='myRigidBody', active=True, iv=(10, 0, 0), b=0.5, sf=0.4 )
