Q:Making a trainer for GTA IV

Postby Sn1p3r » Fri Dec 19, 2008 5:06 pm

hey could some1 help me...

i tried making godmode with MHS 4 GTA IV

i used the search for unknown, then increase and decrease subsearch
found the godmode address, locked it, but i still get hit (the health that goes away shows red)

by that "shows red" i mean, that when u get hit, it normally shows a red part (the hp u lost)for a second next 2 the minimap, but if i lock the godmode address it will show it, but it wont go away

so ye... how teh heck do u make the godmode?!

you could've found the following things:
fake adress
screen only adress
wrong adress.

you could try, watching what accesses the adress, and then NOP - ing that code.
if this doesn't work u found the wrong addy.
u might even do it the other way around( i mean 0 is full life, 100 is dead for example)

Sorry if it's a little late but if you guys want to make a trainer or ANYTHING for GTAIV then there is only 1 answer that is the solution to all, scripthook.

This is something that I found to be very very useful rather than memory searching, because this already hooks the game and uses it's own internal functions to make things happen. You can do anything from give yourself infinite health, and ammo to spawning peds, vehicles and more! :!:

They have available the C++ Scripthook and the .NET Scripthook (which is the one I use, but is based off the C++ one). I have already created 3 scripts using it and have another one in production (but kinda lost interest in it for now). :/

Either way it's a great way to make trainers or anything for GTAIV, with one of these you could even create your own side missions. :D

The last statement couldn't be more untrue! It's an 'easy' way, but not the only way. Let me make that clear. I have created several fully featuredmemory-based gamehacks over the last few versions of this title. The reason people have so much trouble is because of the encrypted nature of all the key variables, and xlive which has anti-debugging crap and memory checks. However, it is possible. You just need to do a little bit of backtracing from where the encrypted values get set and manipulate the real values before they get pushed to the stack. Sorry for reviving an old(er) topic, but it would have been very misleading if someone read this.

Important informations should not be bound by whether one post is old(er) or not, i believe...

Anyway, what is this “fully featured memory-based gamehacks” ? I’m curious.
Would you please elaborate more ? Thank you very much in advance...

I simply mean a trainer full of options, not just a 1-2 option deal. It just needs a little bit more time and effort, but it's certainly not un-hackable via normal means. That is the impression I get when I read these statements on the web. God mode, armour, one-hit kills, ammo, vehicle health, stamima, cash, wanted level, time of day, and pretty much everything you can normally think of doing can be done (and has been).

I never said that memory hacking GTAIV was impossible, just not the best route to take with the given tools available for this game.

Sure you can make a standard trainer with the normal memory hack way, health, armor, ammo, etc. But what I want to see is someone make a minigame, create a flame thrower/object spawner, a ragdoll mod, or a teleporter with the normal memory hack method. And I don't mean just a normal teleporter where you can save 3 locations, change your coords, and it's done; I mean one that also allows you to set a blip on the in-game map and teleport to that location. Did I mention that my Handheld Teleport Device also has all flying rat and stunt jump locations available? My Super Spawner Script allows you to spawn ANYTHING, place/rotate it anywhere, and then save the spawned objects to a file for use later. You can even create your own little stunt ground in the middle of the water, check out some of the vids on youtube!

The only point I was trying to make was that it can ALL be done via scripthook!

Certainly didn't sound like that initially, and that's the only reason I posted. When the game 'first came out' for example, there were no tools of this sort. It wasn't just 1-2-3 from the get-go on this. Anyway no worries. I'm not here for drama, which I sense is all i'll get in return. It's a nice scripthook; I don't doubt that. Laters..

Nope, nope... no drama; I just had to clearify myself. ;)

I only said there was 1 solution for simplicity sake. Seeing as how Sn1p3r already tried searching for values directly, I simply gave another ultimate solution for this specific game. I see now how my statement could've been misconstrued. :oops:

Anyway since you do have most of the hacks available, why not make a new topic so others can learn from what you have? I also attempted direct memory hacking for GTAIV but to no avail, I couldn't find correct complex addresses and xlive is a pain. The scripthook provided the means to make my own trainer and then some.. just a suggestion.. :D

Also, just a little FYI.. when the game was first released Alice was not far behind it (< 1 month). So even though there was no scripthook, there was still LUA scripting. :P
