Open ScriptFunctionList.cs
Find the following
public enum tilecolors : uint
{
// A,R,G,B
Mud = 0xFF5E250C,
StoneLight = 0xFFC0C0C0,
Lava = 0xFFEE0012,
WaterDeep = 0xFF053E65
};
insert a new color by adding its name, then its color value in hex.
Color =: Alpha,Red,Green,Blue
ex: Mud = 0xFF5E250C (you have the , if its not the last member)
You can get color codes from paintshop and photoshop if ur lazy.
The map editor compiles this automactically on run, your fucked up comp might palce the new dll in the same directory though so you might have to manually move it to your noxtools directory.
