Hello everyone-

I'm making a level picker screen for my game, where I want to have a scrollable list of levels inside a "frame" graphic. I know how to do everything I need except how to perform clipping so that the level names (pasted sprites) don't go through this frame.

I know of a clunky solution to use a frame which is the thickness of the bitmap font and draw it last so it will draw over the bottom/topmost lines. But I'd like to have a thinner frame with a nice clean clip of the text above it.

Any ideas?

You could size the sprite to whatever you need, then adjust the UV coordinates of the sprite to suit the area of texture you need.

If these are your only sprites, then you can set the sprite draw area by using the SET SPRITE VIEW command from my plug-ins.
