When making a simple tower defense game I've come across this seemingly simple issue. I want to make it so when the mouse is hovering over a tower, an object will popup over the tower that is suppose to represent the towers range. This sounds very simple to do, just make the range sprite the same size as the range. But that isn't a proper calculation for the range as I've learned. What would be a simple way to make a proper range sprite for a turret?
