How to compile it
Hi,
Writing cause there is zero information on what platform, language, compiler should be used or even how to use it after we compile it.
I was struggling with internet's mess by trying to find ANY solution to draw a simple crosshair on a fullscreen game and no ahk, easyhook, hooking, reading processes or hooking dlls was working. This project is next to test, but to be honest I don't even know where to start as readme explains nothing.
Get Visual Studio 2017, click the generate.bat in the folder. A build folder will be generated with a Visual Studio solution that you can use to build the project. Once you compiled the project the binaries are in build/runtime/(architecture)/(configuration)/ You can then inject the overlay.dll into any process and it will show the overlay.
