Cheat Engine

[whoarere]

Well, first of all, I'm trying to use Cheat Engine on Halo Trial because it seems more legal than online games with other people.

I wanted to make a trainer for Halo,
and I finally got the concept of Pointers.

When you find the values of the ammo adresses,
none of them are static, which doesn't work in this case.
I've tried finding the pointers as in the way from the cheat engine tutorial (6 and 8 I believe),
but when I type in the probably Hex value (yes I ticked the Hex box and pressed New Scan before I pressed First Scan...), no adresses show up.

I know it has been done before as there are millions of trainers available for Halo already, and I wanted to practice using the full features of Cheat Engine.

Can anyone please help me find the pointers for the adresses I've found?
(Someone who's done it in Halo Trial?)

The adress you first got, are you sure its not a static adress? try the adress of witch contains the value you first got, dont search for the pointers.
and see if that works.

I downloaded Halo trail and tried it out, your right it aint static, but the adress i found did lock the ammo, when i froze it in CE i had 60 rounds left after shoting all the time, but i notice the code shifts when next checkpoint loads just before where they drop the worthog, my infinite ammo was not infinite anymore, i had to find the second code and freeze that aswell.

Do you know how to NOP it.
example- Take the ammo address and right click it. Choose (find what writes to this address)
After you shoot the gun and it writes. You'l see it in the box that had popped up. That will control the decrease of ammo for those types of guns.
One set for human weapons.
Two sets for plasma weapons. (alot harder to find if you'r new to CE)

But by far the best way to do it is using map based addresses.
These values DO NOT change so normal scans wont help.
You'l need to use a modding tool to change these values so you can scan for them. Then make pointers.

Look at the tank for example. It has inf ammo, why because it has no magazine.
Normal weapons have 1 magazine. Just change that to 0 and you got inf ammo.
Plasma weapons need there heat recovery and heat loss set to 0. or something like that.

hope this helps some

I found it! i just did it i cant belive it,and i am a noob.yippy, if you want to know how i do to get it to work il tell you , but you will have more fun doing it yourself i think.

This is what happend before i did it, Ammo was unlimited with the none static code frozen until the next checkpoint loaded and i hade to find that code and freeze it.and so on...

but this makes the ammo stay at 60 all the time and even when next checkpoint loads it stays at 60 and magasins animates almost as ussual , but will stay at the same amount after animation, the magasins in the left upper corner.

I did my first simple Trainer thanks to you, and here it is, please try it out ,

Oh, I was talking about the multiplayer games, but I think what you did will work the same too. How did you do it?

Unfourtunatly the trainer only seems to work for singelplayer campaing,
so i missunderstod you at first, i never tried for the multiplayer,
but i gues it is just a smal change in the memory,since it seams it's caused by another adress and value for that.

anyway what i did whas to search for the adress and value of the bullets, and when i found it i searched values close to this adress and found the one adress that made the bullets decrease and changed its upcodes, this made the weapon stay at it's orginal value all the time.
so you should search for a possible value within close range of this bullet adress and maby you are lucky like i was, il give it a go and see if i can find it aswell, but when it comes to using this online it might be a little harder, if you are not the one that hosts the multiplayer game, if you are then it might work i think, but if you are not the one hosting the game, then i think you need to look into about sending pakages and stuff like that.


By the way what Pingo means is that you could use a Halo map editor and change the values of the maps yourself,and ones you found the values you need create your own pointers for these adresses and values.
and finding these values from the static adresses might be a little over the edge.you would have to search thrue many adresses and values and it would take forever to find exactly what you were looking for i think.

not that ive ever played the game before, but i read all your posts and id just like to point something out.

There is a posibility that once you enter multiplayer version, the game server may check details like amount of ammo etc, so you may only find it working as a client sided effect.

Thats even if the mulitplayer version client actually controls ammo, you may find the server controls it all which is why you can find it in single player mode but not multiplayer (would also account for no results being displayed i think)

However you may be lucky and it may work.

Another note to mention about addresses not being static, its likely the address is something like Process+jump bytes.

Since the process address space will change everytime you run the game, so will the addresses, however, if you notice the addresses only change the first 4 bytes for example, but the rest stay the same, then its game.exe+offset.

CE Trainer i think handles this way of adding addresses, so you could just do it like that. but like i say, providing thats the reason for dynamic address

Got it working for multiplayer aswell, I hosted a game for me and a friend and it worked perfect, il upload the trainer soon, but this is just unlimited ammo for the rifel, so it worked atleast when i hosted the game.

I dont know about the full game, but i just notice that my trainer i just created only works in slayer , just tried it on capture the flag and it seams it uses another adress, nasty programers:( a trainer for every mode, thats to much.
