How Shaders work...

Subject: How Shaders work... Tue Jan 31, 2012 2:27 pm

Shaders are living in your SCRIPTS Folder.
You just need one Shader for your Map with all Informations in it…
For Example i post the Shader of my Deathrun Map.
If you want to put some Informations in your Shader….you have to put 2 // before it!!!
Same if you want to disable a line…like this….

Code:: textures/Deathrun_kas/13:q3map
{
surfaceparm slick
// surfaceparm nodamage
}

Now just the slick line is working…nodamage is disabled!!!

Here my Deathrun Map Shader:

Code:: ////////////////////////////////////////

If you making a new Shader its IMPORTANT to edit your Shaderlist.txt file.
So if your Shader calls test.shader… you write test in your Shaderlist…

EXAMPLE: there are 3 shaders active…test, ladder and water!!!

Code:: //********************
//*****Shaderlist*****
//********************

test
ladder
water
