Quote: "how to add money"
And do what with it? Money is there for more than staring at. If you don't do anything with it, then there's no point in it being there.
If you're just wanting a money number to show up on screen, then here's how to do it:
:state=0:dimvar=money,setvar=money 10000
:state=0:hudreset,hudx=24,hudy=8,hudsizex=16,hudsizey=16,hudimage=gamecore\huds\numeric2.tga,hudname=moneyhud,hudtype=6,huduservar=money,hudmake=numeric,state=1
Save that as a script and slap it onto a dynamic light. A new number will show up next to your normal HUD showing you how much "money" you have.
What you do with money after that is up to you.
The one and only,
