Ian and Alexander cover a number of ways available in Unreal Engine 4 to trace/ray cast. Tracing is an integral part of gaining information about the level, state of Actors, or even gettinga reference to an Actor at a location. Beyond this, traces that return everything they hit can be leveraged to determine anything from the number of walls around an object to a target location to if a character can fit through a gap.
