Hello, I understand you can change a particle's color, like in PHOT's case. I know it uses ctype. I don't know what to put before that to say that
parts[i].ctype &= 0xRRGGBBAA
means
The current particles color is in hex, it is RED RED GREEN GREEN BLUE BLUE ALPHA ALPHA
I don't understand if there is a 'ctype = PIXPACK 0x*" or something of the like.

No, tmp is a temporary value that can be used for whatever the hell the dev wants to use it for.

I figured it out. I can just use tmp and graphics.c. Please lock this topic.

You can't.
