# contactEvents

> Controls whether this shape produces contact events which can be retrieved after the simulation has completed. Any contact events can be used to call the assigned _callbackTarget. A contact event is produced if either shapes involved have contactEvents enabled. A contact event will produce a PhysicsCallbacks.IContactCallback to the _callbackTarget for both shapes involved.
