Ok, I see what your saying.
I have all the anchor points set up for my tiles and sprites. I should place my sprites approximately where I want them to go, and then during run time, I should check which tile the is sprite is standing over, and snap it to the center of that tile.
I thought about it doing it this way, but I actually wanted to change the way the editor worked so my sprites would snap to the center of the tile when I place them, before run time. That way, I can see exactly how they would look. Would it possible if I subclassed the TK 2d sprite object?
