Expand description

A fixture definition is used to create a fixture. This class defines an abstract fixture definition. You can reuse fixture definitions safely.

Fields§

§shape: Option<ShapeDefPtr>

The shape, this must be set. The shape will be cloned, so you can create the shape on the stack.

§user_data: Option<D::Fixture>

Use this to store application specific fixture data.

§friction: f32

The friction coefficient, usually in the range [0,1].

§restitution: f32

The restitution (elasticity) usually in the range [0,1].

§restitution_threshold: f32

Restitution velocity threshold, usually in m/s. Collisions above this speed have restitution applied (will bounce).

§density: f32

The density, usually in kg/m^2.

§is_sensor: bool

A sensor shape collects contact information but never generates a collision response.

§filter: B2filter

Contact filtering data.
