Particles : colour reference
by Mr Meikel · in Torque Game Engine · 02/26/2006 (11:53 am) · 8 replies
Hi,
I'm attempting to make all of my guns have different particle effects, but cannot find any reference for the 4-digit numbers used in the datablocks.
eg:
colors[0] = "0.8 0.2 0 1.0";
colors[1] = "0.8 0.2 0 1.0";
colors[2] = "0 0 0 0.0";
My guess is a 3-digit RGB and then an alpha, but I could be very wrong! And of course RGB would be up to 255, not 0<=x<=1 !
So, anyone got a reference table/image they can share?
edit: also, can anyone recomend a particle tutorial? I've got ideas in my head, but no idea how to recreate them!

What would then be the scale for mixing colors then? 0-1 dosn't leave alot of room for color combos.

Sure it does, you use decimals. Percentages. May be a little tedious in figuring out the right amount of each, but eventually it comes pretty easily.

127 = 0.5? ..use photoshop as reference?

Just take your normal 0-255 color value and divide by 255 to convert it to your floating point.

correct. The value IS (R, G, B, Alpha) as a 0-1 value. Just think of the color values as percentages from 0% to 100% except their reprecented as a decimal instead.
With a little basic math or a color converter (there's several online or you can make one) you should be able to represent just as many, if not more, color-combinations as with 0-255 values or Hex (00-FF) values.
For those who are art-deficent, like me, a trip to easyrgb.com can be helpfull too.
