I have been thinking about this for a while and I decided to post it.
You know when you are making a Sonic wad, you make the blue part of the sprite be able to change color,and you put this in the S_SKIN:
So, when you put your wad on SRB2, only the blue parts of the sprite can change color.
Nothing more, nothing less.
What if there was an additional thing that you can put in the S_SKIN, such as this:
startcolor = 225
startcolor2 = 128
Which would make the red of the shoes be able to change color separately.
Like the Blue parts could be grey, and the red parts could be green, for example.
I think this all might be possible by the use of a console command, such as:
This would appeal to people new to the game being able to use a command to change parts of the body's colors, and put there Fan Characters in the game without the use of a character wad.
