Hmm... I think my terrain ordering is a little off: (This is
One way or another)
I'm a bit confused as to the correct way to handle the special terrain nibble. As I understand it:
8 signifies that the piece should not overwrite existing terrain
4 signifies that the piece should be drawn upside down
2 signifies that the piece should subtract from the existing landscape (so far).
But if that's the case, something really weird is happening here.
Edit: Uh oh, I may have to upgrade the Lemmings DS rendering engine and editor to handle these subtractive shapes, I kinda screwed up when I wrote the system. Darn.
Edit 2: Yup. It was my fault. I was handling subtractive shapes incorrectly within the level renderer. I fear I may have broken compatibility with all of the custom Lemmings DS levels, though. *checks* Nope, it still works. Nobody used my 'Zero Overwrite' flag, because it didn't really make any sense in its previous state. Now everything is groovy and great, hooray!
