Description
Constant: integer PRIM_MATERIAL = 2;<videoflash>6OXYO61kQCA</videoflash>
The integer constant PRIM_MATERIAL has the value 2
Sets the prim material. Material does not affect mass, but does affect friction, bounce (elasticity), and collision sound. On a wood incline of 33 degrees, the example script below gave the following results:
| Type | Velocity (m/s) | Distance (m) |
|---|---|---|
| Stone | 0.453181 | 0.361655 |
| Metal | 5.475444 | 10.211180 |
| Glass | 6.483150 | 11.678304 |
| Wood | 2.154549 | 9.433724 |
| Flesh | 0.351543 | 0.188043 |
| Plastic | 4.502428 | 9.590952 |
| Rubber | 0.374964 | 0.187106 |
