Another question about colors

    sorry if I am still a bit confused here, let me just explain exactly what I am trying to do. I have a sulfur element, I want that element to produce a flame that is blue when it burns. What would be the best way to do this? Please provide a detailed description.

    You would probably have to change the fire code a little then. You could add this in pyro.c after line 56:
    if (rt == PT_SULF)
    parts[r>>8].ctype = PT_SULF; (fire uses ctype already, but I don't think it does anything with it, so it's okay to use)
    Then in fire.c, at line 9 do:
    if (cpart->ctype == PT_SULF)
    {
    *colr = xxx;
    *colg = xxx;
    *colb= xxx;
    }
    This will make the fire it produces turn blue, and you don't even need to create a new graphics/update function this way

    since I don't have the most recent version of the code is it after the two brackets because that would be line 58? Either way I am going to give it a shot

    You would put that before the two brackets. I tested this code a while ago, and so i'm sure that it works now.

    still doesn't seem to be working for me here are my pyro.c and fire.c pastebins



    Maybe it has to do with my powder.h code or I need to put something in the sulfur code because right now its only burning when I ignite it with fire.

    You should put '= rt' in line 59
    Also, in line 58, it just says || PT_SLFS, you should change that to || rt == PT_SLFS
