Autotile Tile IDs

Introduction

This was something I was bored enough to experiment with and learn a little more about. Okay, it was more like I had to since I'm writing a Tile Substitution / Placement script that -- as of this writing -- will be up very soon. Some of the information here is probably a no-brainer to those who worked with autotiles before.

Autotile Indexes

Normal Autotile Indexes

Each autotile contains 48 (ranges from 0..47) different tiles which appear in different directions. I have put together a list that explains all 48 of them should you ever want to use this information in some way. Here they are:

Tile A1 Block E Indexes

Behavior of autotiles for waterfalls. Indexes 4 through 47 are the same.

Tile A3 Roofs and Walls / Tile A4 Walls

Behavior of autotiles for Tile A3 Roofs, Tile A3 and A4 Walls. Indexes 16 through 47 are the same.

Autotiles & Tileset Tile IDs

Tile A1 Tile IDs

Please look into Tile A1 Block E Indexes for info on the Block E Autotiles

Tile A2 Tile IDs

Tile A3 Tile IDs

Please look into Tile A3 Roofs and Walls / Tile A4 Walls for info on the Roof and Wall Autotiles

Tile A4 Tile IDs

Please look into Tile A3 Roofs and Walls / Tile A4 Walls for info on the Wall Autotiles

Tile A5 Tile IDs

Tile B - E Tile IDs

• B Tile B Set (0..255)
  
• C Tile C Set (256..511)
  
• D Tile D Set (512..767)
  
• E Tile E Set (768..1023)
  

Formulas

Now you're probably wondering, "okay, now what?" So say you need to call them or change them through the $game_map.data[x, y, i] = value call and you need to use an autotile for some reason. See, autotiles can't shape themselves, so you need to find the tile ID that best suits where you're putting a particular autotile. Now if you can't be bothered to remember all of the tile IDs and such (and honestly, I can't say I blame you because I wouldn't either), then you can use a quick formula for each tileset.

Formula for Tile A1 - Tile A4

2048 + (48 * autotile) + index

Autotile: 0..127

Index: 0..47

Formula for Tile A5

1536 + (column + (row * 8))

Column: 0..7

Row: 0..15

Formula for Tile B - E

(256 * set) + (column + (8 * row))

Set: 0: B, 1: C, 2: D, 3: E

Column: 0..7

Row: 0..31
