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.
