Hey everyone, I am currently making a 2D game (again), but currently my guy can only jump around in the empty 640X480 screen. I don't want to hard-code a map into the game (which would really suck), but I don't want just a few rectangles for obstacles or something. So for a map format, I was thinking of how I might be able to easily edit a map and add miniscule details, and I thought of creating a 640X480 monochrome bitmap and using the "colors" to define which areas (pixels) are obstacles, i.e. you can't go through them. That way I could edit a map using Paint, and I wouldn't have to make a level editor or anything.
Is this a good idea, or should I think of something else?
