Hey i've heard you are working on a star coin selection screen, but you were having some issues with the tile creator/destroyer sprite. Perhaps i could assist.
Yeah, I'm trying to make Mario control the Starcoin select screen by moving into different zones and make a block appear under the right Starcoin. It does work, but only 1 time. The blocks doesnt reappear or disappear after selecting the 3 starcoins...:\
In case you didn't know i've created a star coin selection screen mechanic in the past so i could help you out with that, http://nsmbhd.net/post/45289/
Your mechanic look a lot like the one I made, and probably work like mine. There's a lot of chance that you already know how to make my mechanic work...
