Available on crate features GCDirectionPadElement and GCPhysicalInputElement only.

An object conforming to GCDirectionPadElementrepresents a four-way directional control element.

A direction pad element contains a common grouping of 2 axis inputs, which can also be interpreted as 2 sets of mutually exclusive button pairs. Only one button in each pair, {up, down} and {left, right}, can be pressed at any given time.
