Summary
Function: list llGetPhysicsMaterial( );
Used to get the physical characteristics of an object.
Returns a list in the form [ float gravity_multiplier, float restitution, float friction, float density ]
| • 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.
Caveats
- A collision between two objects with restitution 1.0 will still not be perfectly elastic due to damping in the physics engine.
