How would i go about creating scrolling containers, for example, a container containing a list of all levels to select from that can be scrolled up and down (or left and right) using touch controls.

I'm trying to think of a way to do this but keep coming up short since there isn't any way to contain sprites to a specific area so they would be visible outside the container when scrolling.

Actually, you can restrict sprites to a rendering rectangle, using SETSPRITESCISSOR - sorry I don't know the specifics, but look it up. For each sprite you could set the same rectangular area on the screen, and the sprites would only be displayed inside that.

I am the one who knocks...

Van is correct, using a scissor clips a rectangle so sprites will ONLY render in that rectangle. All you then have to do is code a routine to feed your text/sprites at the top or bottom whilst keeping track of whats clicked on (with sprites that is easy with the spritehit command)
