Bring this guy to most of your conf. He just sparked kotlin to be taken seriously

This is one of the best presentations in KotlinConf, I laughed a lot and learned a lot 🤣👏

It's the best 😁

I like how he started with hacking and ended it with how to fix bugs and patch libraries. Hacking is bad, we don't do that, unless we have to fix issues. 🤣

Here's something that would be really cool and make this much better (and I've done this in languages like Julia): hosting a REPL in the game When you're hacking a game internally, the majority of development time is spent on the very long feedback loop of having to do the following whenever you make a change. - recompile the dll - restart the game, then load the map/state (which sometimes takes more than 1-2 minutes) - reinject the dll And you will be making a lot of changes very frequently, so you end up wasting a lot of time like this. You could streamline the experience more by having a proper hooking system, so that you only have to recompile the dll, uninject the dll from the game, and reinject, all without restarting the game. But having a REPL is even better. Though since Kotlin/Native uses LLVM, and I presume is AoT compiled, I am not sure if there's any good REPL for it. With a REPL, you could also do exploration, which is quite necessary, e.g. to test your patterns and poke at data.

Small correction: The windows API is NOT written in C++, it's written in C, their examples say "C++" but it's 100% C code. In C++ an equivalent API would look nothing alike.

I don't really need to hack any processes, but I sure do want to right now!

hahaha, I definitely wouldn't have thought of any of this but it was fun. Patching a bug, or writing a plugin? That sounds really cool, and useful!

So how did he work around the WINAPI thing in his injector if not with a c++ wrapper?

@asm0di0 Жыл бұрын

Probably makes sense to read the code of injector4k

Hey! Feel free to create an issue in the repo, I'd be happy to walk you through Not sure what you mean by solving the winapi thing though

@thanosfisherman Жыл бұрын

@@cargeh thank you. I mean since Kotlin native does not yet support this WINAPI stdcall what was your workaround? How did you do it in other words if not with a c++ wrapper.

@balen7555 Жыл бұрын

@@thanosfisherman Normally, all you do is LoadLibrary your dll in the process memory, and that will call the standard DllMain entrypoint. What Injector4k is doing is besides LoadLibraryA it'll also use another CreateRemoteThread that will execute a function from the loaded dll, that doesn't have to be the standard DllMain with stdcall calling convention. In short, his workaround is in the dll injector.
