[Autotiles] Waterfalls, Swift Water, and Lava!

First, there's the "swift water". This is what is used in Fr/Lg to stop the player from surfing with a message along the lines of "The current is far to swift to surf here." (paraphrasing).

I tried to find an autotile for this and failed, so I extracted the tiles from the ROM myself and repackaged them into a RPG Maker XP/Pokemon Essentials friendly format:

An example of where these were used in-game is Two Island:

I love caves behind waterfalls, and wanted to make a neat doorway entrance for em lol.



*Autotile is in 2 parts: top, and bottom.

I improvised a bit with this one, since I wanted a slightly more violent lava than what was using in-game for R/S/E. The result is a fully animated lava autotile, vs. the "spotty bubbling" that the original game used:

I also created some custom sprites for use in "lava surfing":

Several people expressed a desire for a sideways waterfall autotile, and so I tried my best to draw one:

[IMPORTANT! READ BEFORE USING!]
*There were several logistical issues with creating this that I could not find a decent solution for:

1) The largest issue is with the tile alignment. Since the only way to have the player move up and down the waterfall without it looked bad requires and "up and to the right" move route, I had to try to displace the waterfall alignment, and align it to two different areas simultaneously.

The result means that the waterfall does not like up perfectly with the tiles at the top:



...My solution was to draw custom transitional tiles, as seen in the above example:


*Put these on the tilesheet you plan to use the waterfall with.

--------------------
2) The second issue with the the terrain tagging and the way waterfalls are set up in Essentials. The waterfall "crest" (top) needs a different terrain tag than the rest of the waterfall does. Since you can only assign one terrain tag to an autotile, regardless of size, the best solution I can think of would be to put a "dummy" invisible tile on your tilesheet, and assign it the waterfall crest terrain tag (default: 9).

The other (much better) solution would be to use Klein's Unlimited Autotiles system for the sideways waterfalls. It's a bit tedious to set up, but it works very well.

[NOTE]: This resource does NOT include the code edits required to make sideways waterfall climbing work! I am not a great coder, and do not feel capable of writing such a thing myself. If anyone wants to help me out by writing the edits required to the waterfall hidden move code to make it work with sideways waterfalls, please go right ahead!
