hi I want to write a piece of code that allows me to control the dpad or left joystick with panning or dragging the screen left right up and down so that it works anywhere on the screen without a joystick picture on the screen with just touching your finger and it moves the player left right up or down like a first person shooter or action game or dpad or joystick but mostly dpad and joystick like a video game controller. can you help me?
