Class: R3d.Body
Description
Sets the body angular damping. Damping is the effect of reducing the velocity of the rigid body during the simulation (like air friction for instance).
r3d.Body:setAngularDamping(damping)
By default, no damping is applied. However, you can choose to damp the linear or/and the angular velocity of a rigid body. For instance, without angular damping a pendulum will never come to rest.
The damping value has to be positive and a value of zero means no damping at all.
WARNINGS: setting damping a negative value will crash your app!
Parameters
damping: (number) the new body angular damping, default = 0 no damping
Example
player1.body = world:createBody(view:getMatrix())
player1.body:setAngularDamping(2)
