Do you
only want cheat
codes, or will "cheats" in general do?
Because there are some ways to make cheats through clever implemetation. One, for instance, might be a fake wall in a room, and behind it is a very powerful gun with a bucketload of ammunition.
Of course, if you're feeling a little more creative you can do much better. One of the simplest is "God Mode". Now, the way I'd go about it is use the fake wall technique and have a corridor behind it leading to an item--basically any item will do. Then, I would attach this script:
;Artificial Intelligence Script
;Header
desc = God Mode Item
;Triggers
:state=0:hudreset,hudx=50,hudy=90,hudimagefine=[image with info like 'God Mode Activated],hudname=godmodeprompt,hudhide=1,hudmake=display,state=10
:state=10,plrdistwithin=40:state=1,playertake,coloff,plrsound=audiobankmiscping.wav,hudshow=godmodeprompt,hudfadeout=godmodeprompt,state=11
:state=11,always:plraddhealth=9999
;End of Script
I'm not
certain that the above code works but it should. There isn't a way to turn it off, and it stops at the end of the level, but it's better than nothing if you ask me.
