Regression in Table Autotiles (RMVX)

[sorlok]

Issue 107 fixed a problem with table autotiles appearing below grass tiles. Now, however, table legs appear above some tiles they shouldn't.

How it should actually look (RMVX):

The actual tiles used here are circled below:

That's terrifying.

The tiles that are implicitly placed above the table legs even though they're on the same layer are of A4 (Walls) type. Of course that interaction is not documented in the reference.. would you mind testing if there are any other tile types that occlude table legs when placed below? I have already written a fix for the corner case you outlined, but it would be nice to fix them all at once.

Sure, I'll try all the default tiles and get back to you.

Here's all of Tile Set A, in the same order as in the palette.

Thanks. Can you send me the map.rvdata for this?

[sorlok]

Sure! Here you go:

There's another problem with table legs that is probably easier to fix at the same time:

Note that the table legs on the very first row are not shown at all, because the tile they are connected to is not in the Viewport.

It's been fixed already: 4d97a17

[sorlok]

Ah, fantastic! I'll merge it and check it the next time I reboot to Linux.

Thanks!

@Ancurio Just checked, and 4d97a17 indeed fixes the second problem. Any update on the first problem?

I was able to dig into this a bit more, and I have a provisional fix:
29b7588

There are a few things that could be improved upon in this solution:

1. I think that the inner check (line 640) is actually not needed; we just need to process "special" tiles in reverse order.
2. I'm certainly missing something in the isSpecial() function, since I am not so familiar with RPG Maker tileset numbering.

Regardless, this hack fixes my table leg problems.
