"Names" (class names, function names, variable names, etc.) do not make it to the final binary: you loose the ability to see class names and their locations. It takes a lot of time, is difficult, and you never have the same 'names' that the original programmers intended. If the game is closed source, you have to reverse engineer it to understand the ins and outs of the game to be able to say this.
rince and repeat until you find something. somewhere else in the data section or in the heap) try to find any code location which points to this new location. If it happens to be in a code section, you have a match. Memory scanning: the engine search directly in the process address space for anything that points (or not very far) to the interesting location. Basically, when the code is accessing the value you are searching for, it does it through some instructions which have a memory operand pointing directly (or not very far) to the interesting location. Statically: by disassembling the code and searching for any cross reference which point to the location of interest. I'm not familiar with Cheat Engine but this can be done in various ways: To answer your question, yes, it points somewhere in the module named ac_client.exe. Once an executable is mapped into the memory (though what is called the OS loader) it has a different "shape" than on the disk, so an offset is not the same thing as a RVA. Technically this is called a RVA ( Relative Virtual Address it's relative to the base address of the module): there a difference between an offset (which applies to the flat file on the disk) and a RVA (which applies to the file once mapped in memory). So at the address base you have the PE header and then a lot of structures, then the sections of the executable, etc.Ģ) Next is the Image Base + Offset (ac_client.exe + 0x10F4F4) - does the offset mean it is taking you to a location or function inside the process from the starting point? Yes, but more specifically, it's the base address of the PE (Portable Executable) once mapped into memory. Still kind of confused could someone explain how it all works visually. Also ac_client.exe + 0x10F4F4 -> 0x50F4F4 - people say that 0x50F4F4 is the local player base class but how do I know this if I was not told this? Does this also mean all game variables are all in classes?
Now I will need to find the static address, since there is no direct pointer to health, I click on “find what accesses this address” option - does this mean I am trying to find a function that is using or passing in my dynamic health variable?Ĥ) After finding the static address for health value. I found the dynamic address of the health. I am new.ġ) Lets say the Image Base address of ac_client.exe is at 0x4000000 - does this simply means that the beginning of the process is allocated at that memory address?Ģ) Next is the Image Base + Offset ( &ac_client.exe + 0x10F4F4) - does the offset mean it is taking you to a location or function inside the process from the starting point?ģ) In Cheat Engine I loaded Assault Cube. Please help me and explain anything in simple form.
If (Aimbot.currentTarget = "0" || Aimbot.I am trying to start learning how to code game cheats in C++.īut at the moment I want to understand the layout of memory and etc - I have a few questions to ask and will use the game Assault Cube as reference. yup.Īnyway I hope this helps someone and kudos to AHK community for some of the functions, especially the memory functions (of which I wrote only one, sadly -_-) and google for being awesome source of information for uneducated fools like me.
Also was my first test with AHK_L classes so. Was planning to finish it but completely lost interest in it so figured I'd post it here for educational purposes.Ĭurrently, it lacks "refinding" the enemies when a round ends so needs to be restarted but, I don't imagine that to be much trouble to add and some other things. I've been working on a memory aimbot using ahk for assault cube (v1.1.0.4), which seems like one of the easiest games for this purpose.
