Texture Packs - coloursofnoise/Resources GitHub Wiki

If you want to replace some textures in the game to make a "texture pack", all you have to do is:

• Get the graphics dump from Useful Links: that will tell you which textures exist in the game, what are their dimensions, how they are called, etc.
• Place the replacement texture(s) in Mods/yourmodname/Graphics/[...], with the exact same path as the one in the graphics dump.

For example, to replace the Forsaken City level logo, you would place the replacement texture in Mods/yourmodname/Graphics/Atlases/Gui/areas/city.png.

If you want an example of a "texture pack" of sorts, take a look at Simpleste. It basically replaces every single texture in the game. With squares and rectangles, but still.

Please note that this will affect vanilla levels as well. This is not what you want if you need custom graphics specifically for your map.

(By the way, if you want to replace Madeline with some other character, you will need 817 sprites. If you do decide to attempt this, you can use the SkinMod Checklist to track your progress.)
