[V-Man]

I've take a look at the video, and it's AMAZING. Where can I download the scripts ? =D

I spent little time on this, that's why it has so many glitches and lack of proper Tetris-oid functioning. The $bottomlimit was my way of sneaking out of having to actually code bottom limits for shapes. My brain burnt out as I started trying to think of how to get each shape to rotate, let alone give the script the ability to dissolve lines (or treat textures like solid objects). I'm sure this'll all be easier with idents that test what texture a given square is.
So, here it is. Don't laugh. XD

[SELECT ALL] Code:

newshape (at [T L1 L2 Z1 Z2 I O] (rnd 7))

Just realized, you'll need a couple non-script things to get this to work:
1) store a texture (floor) by scrolling to your favorite one, then select a different square. (Like floppyspam, this is due to the dynamic nature of edittex.)
2) ac_tetris.cgz
