I'm going through the darkGDK library and can't seem to figure this out....my goal is to follow the sprite around (sprite will be at center of screen the whole time).

EDIT: I think I understand now. So I store the level as an array, and depending on where my characters x and y position is, I would draw the level around that location. And if there is more than one player, its like saying player 1 is at 2dArray[x,y] and player 2 is at 2dArrya[x+20][y-35]. That way you can see each other in game because their sprite is kinda like a pointer to that location in an array.

Well, i will not have time to do this for about a month then....finals are coming up

One way you could do it is simply create a std::list of every sprite currently active in your game. Then whenever you want to render while tracking the sprite, iterate through your list and subtract the position of your sprite your tracking and add the dimensions of the screen divided by 2 to each sprites position, then it will centre on the sprite you're tracking. Make sure you reset the position of each sprite by doing the inverse after rendering otherwise it will screw up after 1 frame.
