}

Expand description

Contact events are buffered in the Box2D world and are available as event arrays after the time step is complete. Note: these may become invalid if bodies and/or shapes are destroyed

Array of hit events

§beginCount: c_int

Number of begin touch events

§endCount: c_int

Number of end touch events

§hitCount: c_int
