ClickSimComponent (Unreal Engine, C++)

This small class creates a component to attach to Player Controllers within Unreal Engine. Its purpose is to simulate a left mouse click at the current mouse cursor when pressing Gamepad A.
Prevents UMG from consuming the A-press by registering a Slate input preprocessor, then fires a real pointer click at the cursor. Includes widget-only mode, by setting bRequireHoveredWidget to true.

SetEnabled and SetDisabled functions that can be called from within engine to turn this simulate on and off.
