llGetPhysicsMaterial

Summary

Function: list llGetPhysicsMaterial( );

	Forced Delay
	Energy

Used to get the physical characteristics of an object.
Returns a list in the form [ float gravity_multiplier, float restitution, float friction, float density ]

• float	gravity_multiplier	–	range [-1.0, +28.0], default: 1.0
• float	restitution	–	range [0.0, 1.0], default: [0.3, 0.9] [1]
• float	friction	–	range [0.0, 255.0], default: [0.2, 0.9][1]
• float	density	–	range [1.0, 22587.0] kg/m^3, default: 1000.0

The default values for friction and restitution depend upon the material type.

Caveats

• A collision between two objects with restitution 1.0 will still not be perfectly elastic due to damping in the physics engine.
