Hello,
Editing these images was a pain in the ass for me, so I made a tool for that 😄
It is very simple and probably has a lot of bugs currently, but if any of you struggle with this issue feel free to check this out:
Click on the image to watch the video:
You have to clone these two repositories (backend & frontend):
git clone https://github.com/dominx99/pixi-animations
git clone https://github.com/dominx99/pixi-animations-backend
and then in both of them.
make init
make up
Next, you can go to browser: http://10.200.31.6/
and play with your tilesets.
There is also a demo: https://pixi-tilesets.chylo.pl/
