Colour & Alpha tutorial Difficulty: Beginner
Category: CS:S > Scripting	Author(s): J2K
//================================== //Colour and alpha tutorial by J2K! //================================== NOTE: The following commands only work in 1.6, this tutorial is to teach you what RGBA is, NOT a script for crosshair colors. I just feel everyone from both versions of the game should learn how to use RGBA properly. Ok, so basically a lot of people at this site are breaking my head by typing commands like cl_crosshairalpha 9999999999999. This is messy, incorrect & unnecessary. So it is time for a tutorial! //Counter-Strike Source colour commands For this example i will use the crosshair color command. cl_crosshaircolor 255 255 255 The three numbers represent the three primary colours, red, green & blue in respective order. The different strengths of each primary colour are added together to form a final mixed colour. This is known as RGB code. The minimum for each value is 0. The maximum for each value is 255. If all three values are 0, you make black. If all three values are 255, you make white. Remember pre-school? Blue + yellow = green. This is still true in RGB code. Now when choosing your crosshair colour, try to keep this in mind, and don't use numbers higher than 255 because it is unnecessary. //Counter-Strike Source alpha commands For this example i will use the crosshair alpha command. Be sure to turn on cl_crosshairusealpha 1 before trying to adjust the crosshair alpha. Basically, alpha refers to the opacity (solid) or transparency (see through) of an object. For uniformity's sake, they have made this work similar to RGB code. The minimum for the alpha value is 0 (fully transparent). The maximum for the alpha value is 255 (fully opaque). Hopefully this guide will put an end to this mindless 999999999999999999 settings i see in far too many config files / tutorials! Jay.

I know it's a tut, but it says "Counter-Strike Source colour commands", then there is a command which isn't a CSS command. You also say "when choosing your crosshair colour", by this you probably wanted people to use this command for changing the crosshair color, not just learn RGB. Still, it's good for players to know the 255 is the highest value, I too have seen people use values like 300 and 999.

The tutorial isn't about crosshair color. It's about teaching people what RGBA is. It belongs in CS:S and CS sections so everyone can learn how to use RGBA properly. The code is just EXAMPLE code. It's a tutorial, not a script. So i won't move or change it.

You cannot mix colors like that in Source, altough it would be nice. cl_crosshaircolor 0 => Green cl_crosshaircolor 1 => Red cl_crosshaircolor 2 => Blue cl_crosshaircolor 3 => Yellow cl_crosshaircolor 4 => Light blue Any value different than that just gives you the default, which is green color. Alpha commands are the same in Source, to get the most visible cross, you would have to use these 2 commands: cl_crosshairusealpha 1 cl_crosshairalpha 255 So, what to do with assessment, you can move this tutorial in CS1.6 section, or you can correct it so it would fit in CSS section. As for now, wrong section.
