All the other sprites seem fine but 000 always places for me like its blank.
Here's a gif of the bug in action:
Haha, I did not know that. That explains it. Thanks.
There's a lot of half-documented stuff out there like this, I would pay handsomely for a richly designed beautiful full colour manual that detailed all of this while just oozing with pixel art and style.
I find it weird that it refers to it as "tile 0", yet Lua is 1-based for indexing. It always throws me off, since I can never seem to recall which is 0-based and which is 1-based, it's rather strange sometimes.
Another weird thing is trying to figure out when it displays the token count versus the character count in the code editor. I think it's supposed to show the char count whenever you're working with an unterminated string, but if I fill the first two or three lines of my code with comments (eg author/date comments) it'll "break" and default to char count for the entire code (unless the first 8-12 characters of the file are actual, usable tokens)
I can illustrate why it's good to have map tile 0 be forced transparent by the system.
To simplify, let's pretend that the system only provides 4 tiles, shared between map and sprites.
Given that, let's make a simple co-op platforming game with a simple background. We'll call it RGB Infinity.
RGB Infinity has simple solid white blocks for its ground and platforms. Maps need only the solid white tile and a transparent tile.
RGB Infinity has two simple players: a red open parenthesis and a blue close parenthesis.
RGB Infinity has one manic AI the two players have to cooperate to capture between them: a green X.
If we set up our tileset like this:
0 - green X 1 - solid white 2 - red ( 3 - blue )
We can then draw the map with this effective tileset:
0 - forced transparent 1 - solid white
And the sprites with this:
0 - green X 2 - red ( 3 - blue )
If we didn't have tile 0 forced transparent when used for the map, we'd need this tileset instead:
0 - transparent 1 - solid white 2 - red ( 3 - blue ) 4 - green X
And, oops, we couldn't fit the game in 4 tiles anymore.
So effectively we get one more usable sprite tile by having the system force map tile 0 to transparent.
