Elysian Shadows

thanks for the help, I'll defiantly look into those things

I don't know what method to use, my first idea was bounding box, but it doesn't work well with rotated rectangles

I'm thinking of making a maze game, where you draw a line threw a maze and points are deducted when you go outside the line, I'm unsure of how the collision would work though any ideas?

here is a picture of my idea, black lines = walls, red line = mouse movement.

How would you use sdl to get mouse input in opengl? To be more specific how do you convert event.motion.x to opengls coordinate system or vice versa?
