Emblem-important-yellow.png LSL Feature Request
The described constant does not exist. This article is a feature request.

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
• 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

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
• 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
mask Flags V Description
DENSITY 1 Indicates that density parameter is enabled and will override the previous value.
FRICTION 2 Indicates that friction parameter is enabled and will override the previous value.
RESTITUTION 4 Indicates that restitution parameter is enabled and will override the previous value.
GRAVITY_MULTIPLIER 8 Indicates that gravity_multiplier parameter is enabled and will override the previous value.

Caveats

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