Rigid Body Controller
The Rigid Body Controller is a type of controller that represents a rigid body in a physics simulation. The Rigid Body Controller is built into the core engine, and it's used for all solid objects that move under the control of the built-in physics system.
Settings
The following settings are available for Rigid Body Controllers.

Description |
|
Rigid Body Flags |
|
|
Initially asleep |
If checked, then the rigid body is initially in the sleeping state. It will not be moved under it is explicitly awakened or another object collides with it. |
|
Ignore force fields |
If checked, then force fields do not affect this rigid body. |
|
Physical Properties |
|
|
Gravity multiplier |
The factor by which the force of gravity is multiplied for this rigid body. |
|
Fluid drag multiplier |
The factor by which fluid drag forces are multiplied for this rigid body. |
|
Wind drag multiplier |
The factor by which wind drag forces are multiplied for this rigid body. |
|
Restitution coefficient |
The fraction of momentum that is retained when this rigid body bounces during a collision. |
|
Friction coefficient |
The coefficient used in friction force calculations. This value should usually be between 0.0 and 1.0. |
|
Spin friction multiplier |
Determines how much friction is applied in the special case that the rigid body is spinning on a single point like a top. This value should be between 0.0 and 1.0, and it multiplies the ordinary friction coefficient. |
|
Rolling resistance |
The internal force that is applied to counteract this rigid body's angular velocity. Good values for the rolling resistance usually lie between 0.0 and 0.1. |
|
Sleep Parameters |
|
|
Sleep box multiplier |
Multiplies the size of the sleep boxes used to determine when a rigid body should go to sleep. Larger values increase the tendency for a rigid body to sleep, and smaller values cause a rigid body to stay awake longer. |
|
Rotational multiplier |
An additional multiplier for the rotational sleep boxes that influences how quickly a rotating object falls asleep. |
|
Network Settings |
|
|
Snapshot period |
The time between network snapshots for this rigid body. Larger values mean that the motion of the rigid body is predicted on client machines for a longer time before being corrected, but network traffic is also lowered. |
