Hey folks ! im trying to hack a building game I tried a lot until I found a function which handles my building progress (at least it seems to be) but there is a problem here let me explain you guys 
So first of all when we create new building we have hammer in hand and showing resources needed to build it like (2 stone 1 wood)
each of those resources are saved in some memory address which is find able via cheat engine pointer scans I made was useless on these addresses totally
so I tried to check what writes and what access to these addresses in building
(those addresses totally functional means if we need 8 stone and we change 8 to 1 it effects the game too and we need only 1 stone now)
So after checking all of addresses I found all of them are controller by this function
| Code: |
1- mov ecx,[rdx]
2- mov [rax],ecx
3- ret
|
and let me explain you some information I found too
the Code line *1* is constantly reading data from the address(which stores needed resources) *WHEN* our mouse is pointing to that object.
so basically its duty is to read the resource amount of needed resource of pointed object with hammer but the second code line which is *2* is only called when we hit the object with hammer in this function
rdx and rax is the same address as we found in cheat engine
and ecx is the resource amount for example 5 is 0000000000000005
the problem here is this function is being called like 199000 times and I can't manuplate this when I make changes to this function anyhow it crashes the game! do you have any idea how I can change this function to work ? or any idea how can I find other things from this function which maybe useful for me ?
i have idea to check if ecx is value between 1 - 6 (which is range of resources needed in this game) and if they are in between that then edit code otherwise skip but I failed what ever I tried it crashs the game can you also help me to achieve that idea I think my lack of knowledge is causing this

with a shared function like that, you need to place a filter that only edits your values or apply special effect when the caller address is XXX
and to check that, easiest way is to use the "find out what writes to this address" on your target value, and in the new address box that opens, press the "More information" button, there should be a button labeled as "S" , this will show you the stack address where parameters that was given to this function, as well as the return address, and in case its only one function that is used to call this one for every other thing there in the game, then you need to keep back-tracking untill you reach something unique
