	// Description: Manages in game controls for both touch and keyboard/mouse devices.

	// This script will be inserted into PlayerScripts under each player by default. If you want to
	// create your own custom controls or modify these controls, you must place a script with this
	// name, ControlScript, under StarterPlayer -> PlayerScripts.

	// Required Modules:
		ClickToMove
		DPad
		KeyboardMovement
		Thumbpad
		Thumbstick
		TouchJump
		MasterControl
		VehicleController
