PRIM PHYSICS MATERIAL

The integer constant PRIM_PHYSICS_MATERIAL has the value 31

PRIM_PHYSICS_MATERIAL is used to get or set the prim's physics material properties.

llSetPrimitiveParams([ PRIM_PHYSICS_MATERIAL, integer material_bits, float gravity_multiplier, float restitution, float friction, float density ]);

• integer	material_bits	–	bitwise combination of DENSITY, FRICTION, RESTITUTION, and GRAVITY_MULTIPLIER and specifies which floats to actually apply
• float	gravity_multiplier	–	range [-1.0, +28.0]
• float	restitution	–	range [0.0, 1.0]
• float	friction	–	range [0.0, 255.0]
• float	density	–	range [1.0, 22587.0] kg/m^3

Returns the list [ integer material_bits, float gravity_multiplier, float restitution, float friction, float density ]

material_bits Flags	V	Description
DENSITY		Indicates that density parameter is enabled
FRICTION		Indicates that friction parameter is enabled
RESTITUTION		Indicates that restitution parameter is enabled
GRAVITY_MULTIPLIER		Indicates that gravity_multiplier parameter is enabled

Caveats

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