hello, If I have a background using a group of tiles that have their own texture for each, I could obviously use a display list to display the background quickly. However, if the texture data changes (a pixel becomes transparent), will the display list still show this change?? The tile still has the same texture, but the data of the texture has changed ... so it would be displayed appropriately even if the display list was built BEFORE the data(pixel) change right? I'm sorry if I didn't explain too well. If there's anything I can explain a bit better lemme know!!

haha, cause I like to ask questions a lot (if you couldn't tell!!)
I'm writing a big ol' program right now and am not quite at my collision detection experimentation yet, so I figured I'd ask beforehand.

yea that's very true, but when I ask here I often get MORE than what I need to know. That is something I LOVE about this place. =)
