Description

Constant: integer PRIM_PHYSICS_MATERIAL = 31;

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

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

When used with llSetPrimitiveParams & llSetLinkPrimitiveParams

llGetPrimitiveParams

llGetPrimitiveParams([ PRIM_PHYSICS_MATERIAL ]);

Returns the list [ 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
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.
