Hey, i saw some cool things that can be done be hacking halo's timers. One of those was rapid fire, I saw this on halo and many other games but for some reason i can't get it to work on any unreal version.

I tried scanning for a 'Can_Fire' or a 'Reloading' but obviously that didn't work at all. I tried looking for timers, reloading sequences and triggers.
All with no result, I currently have a code list longer than my entire screens diameter and I tried nopping and editing ALL of them.

I noticed that my weapon moves and behaves exactly the way I want it to behave but it still just starts the reload sequence and finishes it without reading from the timers (I know, either not possible or i suck at hacking UT)

If anyone has any ideas, suggestions, or already know how to get rapid fire then please help me out.

assuming you're talking single player since online it's handled by the server:
UT2004 uses a tickcount mechanism
This means that it either saves the ticktime of the last show, or the ticktime of the next time you can shoot. Meaning that the value will always increase each time you shoot and stay the same if you don't shoot.

So, to find it the timer for your gun:
do a unknown initial value scan
fire
changed value scan
walk arround but don't fire
unchanged value scan
fire
changes value scan
walk around and jump a bit
unchanged value
etc...

eventually you'll find a bunch of addresses related to firing (e.g used for handling sound), so just try them all out, freeze them and shoot

and again, don't bother with it online, your next shot time is stored on the server, not on your client (thats why speedhack also won't let you shoot faster)

Well, i'll give it a try but does the timer count for all guns or just for that one gun (because you say the timer increases as you shoot)

most likely for each specific gun, but not sure, the weapon swich generally takes longer than the time you are allowed to fire

Well, i tried what you said but i got to 500 addresses and over, i tried with other weapons as well and the best result was 43 so i started using code finder on every single one of them.

Eventually i got some REALLY cool codes so thanks for that but i didn't manage to get rapid fire... but I still found some handy codes that would let me freeze bullets in mid-air or make stuff go instant-kill but from all those codes there was only one wich affected firing speed, it prevented the weapon from firing at all. Thanks for the help anyway, i posted the table on the tables section of the site in case you want to have a look at the codes i found.
