Arduino game controller Answered

I wanted to make a general purpose VR gamepad using Arduino and I thought that if I made a Bluetooth mouse using an HID module then I could get it to press a specific coordinate when a button was pressed. I run into the problem, though, of multiple button presses. The best solution I could come up with was to have it quickly switch between the coordinates but then I can't have it hold down the buttons. How do commercial Bluetooth gamepads work and how could I replicate this using Arduino?
