Expand description

Context for a time step. Recreated each time step. (b2StepContext — step parameters only; see the module header for what the serial port drops)

Fields§

§dt: f32

time step

§inv_dt: f32

inverse time step (0 if dt == 0).

§h: f32

sub-step

§inv_h: f32§sub_step_count: i32§contact_softness: Softness§static_softness: Softness§restitution_threshold: f32§max_linear_velocity: f32§contact_speed: f32

Copied from World::contact_speed (the C reads it through context->world).

§enable_warm_starting: bool
