Kiero-Golang-DirectX11-Hook

This is a very dirty Golang implementation of Kiero Hook for Directx11.
For a QuickStart, you can check out the example folder.

Information

This works due to a little modification of the imgui-go wrapper by inkyblackness.
you can get it with go get github.com/RinLovesYou/imgui-go

!! THIS MAKES A LOT OF ASSUMPTIONS ABOUT YOUR ENVIRONMENT. IT EXPECTS DEPENDENCIES LIKE MINHOOK/DX11/ETC TO BE INJECTED/PRESENT !!

QuickStart

	"fmt"
	"unsafe"

	err := kiergo.Hook(OnPresent, WndProc)
	if err != nil {
		fmt.Println(err)
	}
}

var gInitialized bool
