I want to be able to pop up some sort of input box (e.g. like the edit box) that the player has to fill in with a value before being able to do anything else. It's for an inventory function so time scale =0 won't work for this since it is already zero, but there is inventory functionality happening (e.g. dragging and dropping items around). I also want to have it limit the input to a number. I don't want to check whether the input is a number, but instead I just want to disallow typing letters entirely, such that trying to type letters will not work (e.g. hitting a letter while typing will not make the letter appear).
