Cheat Engine

[bet man]

Hi there, I am playing a single player unity game like shown in this tutorial: youtube(dot)com/watch?v=ofYR1tQU2UY

The same instruction shown in the video that writes his value is also writing my ammo value, probably because the game engine is the same.

mov ecx,[rdx]
mov [rax],ecx
ret

I break trace on the mov [rax],ecx instruction, and make the break trigger when my display ammo address is [rax], it brings me to the results page and I add the address value of [rdx] in the break trace results to the cheat engine address list, and it is not the same value as my ammo value. It is a randomly changing value, where it goes to like 0, then 279018, then back to 0, etc...

My question is, how is he having so much success with this while I am not? Is there some encryption or other variable going on in my game?

To be precise, I get stuck right at the part shown in the tutorial video at 10:36. I tried checking other backtracing videos, but none of them make much sense or match the value types I'm after. I want to become a backtracing pro but info seems limited and I can't find any good resources about it and all the crazy if's and but's surrounding backtracing.

Thanks!
