Do you do this from a separate process at runtime or is it all modifying the executable before you run it? All is done at runtime. By nature of how Windows DLL work, they have a DllMain that's executed every time you load a dynamic library into a running process. From there you spawn a thread and you can do pretty much whatever you want within the same memory space of the games. There are multiple ways of injecting a DLL into a running process, and since I only care about offline games, I don't have to fight against any anticheat and stuff so it is pretty straightforward, it is a very interesting topic to read about to be honest! > I can imagine getting the memory offsets for things like camera transforms being reasonably straight forward with cheat engine Cheat Engine is an amazing tool, for real. I remember using it when I was a kid to do very rudimentary cheating -- just scanning and changing values; years have passed and one day I opened Cheat Engine again to... skip over an annoying mechanic of a game and I noticed it can do so much more! it has a very good debugger, disassembler, memory view, you can even inject your own assembly code. It was the gateway drug that I needed to get started on everything I do. > but mutating the values feels a like converting a train from diesel to electric while it's carrying a load Well, compilers are pretty straightforward (at least, most of the time), it's all about memory layout. If you have something like struct vec { float x; float y; float z; }; Once you find the pointer to the objects you need, most certainly they're going to be each one after the other. This looks like obvious knowledge, but at least on my brain I had to build an extra bridge to realize how simple it is :) (of course things can always get complicated but this is the basic gist of it). And as long as you know your programming language has a stable memory layout, you can map it from your code. I even was able to map some very basic virtual class from C++ within Rust by mapping the virtual tables. What I enjoy the most, is that I learned a lot about low-level programming, assembly, how OS and compilers work together, while having fun playing games, and developing tools that people can use to create pretty images -- it felt like the outcome was extremely positive and it brings me a lot of joy.
