Summary

Function: llSetPhysicsMaterial( integer material_bits, float gravity_multiplier, float restitution, float friction, float density );

Used to set the physical characteristics of an object.

• 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

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

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.

Signature

function void llSetPhysicsMaterial( integer material_bits, float gravity_multiplier, float restitution, float friction, float density );
integer DENSITY = 1;//range 1.0 to 22587.0 (in kg/m^3), default: 1000.0
integer FRICTION = 2;//range 0.0 to 255.0, default values are in the range 0.2 to 0.9
integer RESTITUTION = 4;//range 0.0 to 1.0, default values are in the range 0.3 to 0.9 (note, a collision between two objects with restitution 1.0 will still not be perfectly elastic due to damping in the physics engine)
integer GRAVITY_MULTIPLIER = 8;//range -1.0 to +28.0, default: 1.0
