rigidBody is undoable, queryable, and editable.

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

Return value

Long name (short name) Argument types Properties
-name(-n) string createqueryedit
Assigns the rigid body the given name.
-position(-p) float float float createqueryedit
Sets the initial position (x,y,z) of the rigid body. Default: current position.
-orientation(-o) float float float createqueryedit
Sets the initial orientation (x,y,z) of the rigid body. Default: current orientation.
-active(-act) createqueryedit
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.
-passive(-pas) createqueryedit
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.
-layer(-l) int createqueryedit
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.
-collisions(-cl) boolean createqueryedit
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.
-tesselationFactor(-tf) int createquery
Sets the tesselation factor for a rigid body surface. Range: >= 10 Default: 200.
-mass(-m) float createqueryedit
Sets the mass of the rigid body. Range: > 0 Default: 1.0
-staticFriction(-sf) float createqueryedit
Sets the static friction for the rigid body. Range: 0.0 - 1.0 Default: 0.2
-dynamicFriction(-df) float createqueryedit
Sets the dynamic friction for the rigid body. Range: 0.0 - 1.0 Default: 0.2
-bounciness(-b) float createqueryedit
Sets the restitution (or bounciness) of the rigid body. Range: 0.0 - 2.0 Default: 0.6
-damping(-dp) float createqueryedit
Sets the damping value of the rigid body. Range: -2.0 - 2.0 Default: 0.0
-initialVelocity(-iv) float float float createqueryedit
Sets the initial velocity of the rigid body. Default: 0.0 0.0 0.0
-initialAngularVelocity(-iav) float float float createqueryedit
Sets the initial angular velocity of the rigid body. Default: 0.0 0.0 0.0
-centerOfMass(-com) float float float createqueryedit
Sets the center of mass (x,y,z) of the rigid body. Default: actual center of mass.
-lockCenterOfMass(-lcm) boolean createqueryedit
Locks the center of mass for the rigid body. Default: off
-cache(-c) boolean createqueryedit
Turns caching on (1) or off (0) for the rigid body. Default: off
-deleteCache(-dc) edit
Deletes the cache (if one exists) of the rigid body.
-particleCollision(-pc) boolean createqueryedit
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
-standInObject(-sio) string createqueryedit
Causes the simulator to use a stand in object for the simulation. The choices are none | cube | sphere. The default is none. Default: none
-impulse(-i) float float float createedit
Applies an impulse (instantaneous) force on a rigid body. Default: 0.0 0.0 0.0
-impulsePosition(-imp) float float float createedit
The position at which the impulse is applied. Default: the bodies center of mass.
-spinImpulse(-si) float float float createedit
Applies an spin impulse (instantaneous rotational) force on a rigid body. Default: 0.0 0.0 0.0
-solver(-slv) string createqueryedit
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.
-ignore(-ig) boolean createqueryedit
Causes the rigid body to be ignored in the rigid solver. Default: off
-applyForceAt(-afa) string createqueryedit
Determines how forces are applied to the rigid body. The choices are centerOfMass | boundingBox | verticesOrCVs. Default: boundingBox
-velocity(-vel) query
Current velocity of rigid body.
-angularVelocity(-av) query
Current angular velocity of rigid body.
-force(-f) query
Current force on the rigid body.
-contactCount(-cc) query
returns the current contact count for the rigid body.
-contactPosition(-cp) query
returns all the contact position. One position for each contact will be returned.
-contactName(-cn) query
returns all the rigid body names which are in contact with this shape. One name for each contact will be returned.
