ARGH I CANT TAKE THIS, Game Maker 8 BETTER have this Feature

What I want the most (besides better compression and speed) is better memory management. Besides add and delete, sounds also have discard and restore functions. I would like those for sprites/backgrounds and other stuff if necessary. Also, for non-persistent objects to automatically delete themselves and their properties from non-persistent rooms at 'Room End'. Though I now just put 'destroy instance' in the Room End event... meh.

I love that palette idea. And the object/room importing/exporting would be handy. Room importing might be difficult in cases where objects are not present or altered-and-incompatible.

But I can be impressed by whatever new comes in GM8. :P

If it's not completely rectangular, then the mask also needs to have transparency, therefore it would still be one pixel bigger than normal.
However, a mask isn't actually needed as transparent pixels don't trigger a precise collision.
