Fields

friction: f32

The Coulomb (dry) friction coefficient, usually in the range [0,1].

restitution: f32

The coefficient of restitution (bounce) usually in the range [0,1].

rolling_resistance: f32

The rolling resistance usually in the range [0,1].

tangent_velocity: Vec3

The tangent velocity for conveyor belts.

user_material_id: u64

User material identifier.

custom_color: u32

Custom debug draw color. Ignored if 0.
