Okay, I'm making a top-down 2d game. It has a car. I used rotate sprite with move sprite to make the car move, and it worked like a charm. But then I wanted the "camera" to follow the car, so I used the same thing but substituting the car for the background (i.e. making background move to give the illusion of a camera). I used the exact same code, just replacing the sprite number with the background number when reffering to movement. I did it, but if you turn the car left and want to then go forward by pressing up, for example, the car looks like it's strafing right. How can i make the way the car moves always relevant to the direction of the car?

If the only thing you changed in your code was the sprite number, that would be the problem. You need to also reverse all the movement - for example, if you press the upkey, you want the sprite to move backwards.

Yeah, but that would make so when I facing another direction it would be messed up. I honestly don't think there's a way to solve this besides putting the sprite on a 3d plane and using a camera. Question: How would I do collisions for a sprite on a 3d background?

Ah, I think I get it now. I can see how one might do this, but 3D has always been a better option - DarkBASIC's 2d sprite system is always said to be pretty slow compared to its 3D commands. I'd try that and see how it goes, it will be much easier.
