Struct TimestepLength

pub struct TimestepLength<Comp>(pub Duration, _);

Resource used for fixed timestep without repeats in the same frame (builtin timestep may run the system multiple times per frame).

To modify the timestep at runtime, a system like this can be used:

fn update_timestep(
    mut step: ResMut<TimestepElapsed<NearestNeighbourMarker>>,
) {
    if some_condition {
        step.set_duration(Duration::from_millis(15)); // only update spatial datastructure every 15ms.
    }
}

NearestNeighbourMarker in this case refers to the (marker) component you also passed to the Plugin.
