Expand Input Field for Pointer?

I’m trying to have the player move towards the mouse when clicked and the camera follow around the map, but when I move down the sprite acts like it hit a boundary. Pretty sure it has to do with the input area not extending beyond the canvas. I would rather not change the canvas size, as there are mini games that depend on the canvas being that size. Is there a way to extend the boundaries of the input field like there is for physics?
