How would one go about making palettes for characters?

The_Duskitty

Basically, i need to make a system similar to street fighter and games like that where when you select a character you can change the character's colour, BUT i dont want to have 50000 of the same sprites, so is there a way maybe through shaders to Make it so one a specific area turns one colour, or somehow godot looks for a certain colour on the character and changes it when i ask it to? Thanks for the Help~

make the bits of the sprites that you want to colour  white and then use the modulate function on the sprite to set it's colour(they'll all be the same colour though)

I'm not sure what you mean but I think Elf_ears idea is good. Just make one image where the parts that can change color are transparent and than create a new white textures wich fit into the transparent areas. Than you have a sprite with multiple children and every children is one part that can be colored. Use the modulate function to make the right children the right color. (based on values from your running game)

You could look into godot's support for shaders - they're not the easiest thing to learn, but they'd give you more versatility than just modulating. There's an example of 2d sprite shading in the godot source demos folder.

I'm brand new at GoDot but have a lot of graphics knowledge.  I'd be heading for shaders although as I say, I haven't tried them here yet.  Good luck, be interested to see what you come up with.

Here's a shader to do that:[code]uniform color Color1;uniform texture Color1Map;// Mix Color1 (rgb only) into the output color according to Color1Map's alpha: COLOR.rgb = mix(COLOR.rgb, Color1.rgb, tex(Color1Map, UV).a);[/code]You just need to give it an opacity map for where the color applies, then set Color1 to whatever color you want, either in the editor or in a script. You could duplicate the code as many times as you want to have multiple different adjustable colors. This will blend to a solid color. If you want the underlying texture to show through, (i.e. use Color1 as a modulate/multiply) just mix in [tt]COLOR.rgb * Color1.rgb[/tt] instead of just [tt]Color1.rgb[/tt].
