Generates a tilemap usable for autotiles from subtiles (e.g. in Godot)
We start with a small tileset including all required subtiles (inner and outer borders as well as center tile and variations)
We cut this tileset into according subtiles and save them with the given nomenclature as single files:
tyx.png -> t: Inner/Outer, y: Top/Center/Bottom, x: Left/Center/Right
I: Inner
T: Top
B: Bottom
C: Center
L: Left
R: Right
Special cases are OC0.png and OCi.png for variations of the center tiles. In the current script it's assumed that OC0.png, OC1.png and OC2.png exist. Additionally one tile NNN.png of full transparency with according size is required.
e.g.
 |
 |
| ITL.png | ITR.png |
 |
 |
| IBL.png | IBR.png |
 |
 |
 |
| OTL.png | OTC.png | OTR.png |
 |
 |
 |
| OCL.png | OC0.png | OCR.png |
 |
 |
 |
| OBL.png | OBC.png | OBR.png |
A png is created which can be used for autotiling:
The generated png can be e.g. used with Godot's Autotile:
