Cheat Engine

Hi. Im modding a rts to make units attack in a different way depending on the situation.

I found the function and then the address in the stack with the value with OllyDbg and Ida Pro.

The function address is 4174A0. The attack stance type is in the stack at 12D5D4.

So far this is great. I learned how to call functions with Guided Hacking tutorials. But i still dont know how am i going to change that value in the stack. Or if that is even possible? What should i do?

Changing that value in the stack will change the Attack stance. But also it seems that the value in the stack corresponds to the argument in the function.

Should i call the function and somehow change the argument? Should i call the function and change the function inside to change the argument inside? Or is there a way to change that value in the stack when the function is called?

Pls help. Thank you

You can make a code injection at the start of the function if you want.
e.g. basic example:

Thank you ParkourPenguin.

So you are basically overwritting CL? Or you are just adding in code to the function?

Your example seems simple and effective i will test with it first. But i have little experience with injection in cheat engine.

I want it to make a c++ injection, which i more familiarized with. But thats too much for now.

>Alternatively, find calls to the function and change the argument(s) there. In CE you'd use Tools -> Dissect Code on the exe, then look at Empires2.exe+174A0 and see what calls it.
You could also set a breakpoint and look at the return address the call left on the stack.

I have that already. I have all the functions that lead to this function. But i dont understand how can i get the arguments out of it:

That address in the image below is what calls our function 4174A0.

How do i check the argument that is being passed? I feel like a monkey looking at it.
