Hi all. New user here who new in game hacking as well like to know if there a way to change any in game setting an easy way ??

Example I like to alter the max amount of consumables item that I can carry in any mission from 3 (default value) to say 10 in "Alien Fireteam Elite" so what's the best way to do that ??

Many thanks first for the helps and stay well stay safe.

Any normal way you search for a value to see if it can be changed via memory. If not then you will have to reverse engineer the function responsible for dealing with inventory limitations and then edit the files manually via a hex editor, again that's not foolproof in the sense that there may be CRC checks on the files and such.

Understood. I had attached a screenshot for the setting that I talking about.

The default is 3 (max amount of a item player is allow to carry) but I prefer bigger value and I pretty sure the "change the value and next scan" method won't work to find value like this.

Any ideas are much appreciated. Thanks for your time.

Use "see what accesses this address" and then set the value higher and wait for it to be overwritten. Then start at the read before it writes, or you'll have to start at the write and backtrace it to see where it checks for the max. value.

But how to find the corresponding address ?? There are so many results by searching for '3'.

I totally have no idea how to find value like this .. this is a fix value set by the game which control the "max equippable" item that player can carry.

If I key in "3" it come out so many results and I can't change this value to 1 or 2 or other and do the next scan ..

change your CONSUMABLES to find the pointer that point to 1st(or 2nd) item,dissect the struct,you may get the 0xNN offset that it's MaxEquippable field

Thanks for the tips but it sounds deep to me, looks like it's time to youtube some pointer tutorial video but what key word I should use to search for related tutorial video beside pointer ?? Cheat engine pointer ??

Thanks again.

It's not that complicated, same as you would scan for anything else to start.. just find a way to identify your CURRENT consumables, instead of the MAX, which is your end goal... if you can find your Current count, you can likely look around it in memory to find the relative Max amount.

Find out what's accessing it.. when it's consumed (starting a mission? idk) then follow where that subtraction came from, using the steps I laid out for you previously.

Guess this is a little too complicated for my beginner skill ..
I find out the "what access to this address" for this item and then consume one in the mission but then that's it .. I don't know what to look at to find the number.

If it's possible to gain them in-game that'd make it easier. Basically though, just look at any instruction and walk backwards through it. If you can't sift through Assembly, this may not be the best place to start unfortunately. It's possible, but tedious.
Find out what is changing the value specifically (nop/restore instructions if you can), then see where it's getting the new value from. Just
Keep. Going. Backwards.

There's some useful resources out there that can help you break down how the game works, like Cake-san's UE4 engine table, but still requires you to know a little more than the basics of scanning here lol.
