I want to build a minimap for my HTML5 game, how do I start? : <p>Assume I have a big map which uses a background image as pattern. I want to place a minimap at the corner when I am moving the player around. All I need the minimap to do is to display where my player is in the big map and where are other sprites in the map, using a very coarse representation and keeping their relative location but shows everything in a much smaller map. So I think this is a very basic and simple minimap. My player will be in the middle of the screen (I have already done that) and the minimap will stay at the corner of the screen. If I want to build such a feature for my game, how do I start?</p>
