what would u want to happen without code? And you have to make sure you inject kinda early

what would u want to happen without code?

well ... You're right. I did a test with a simple white walls, but had no success.

And you have to make sure you inject kinda early

Are there any specific injector for this? I was injected after the game is loaded.
If it's not too much bother, could you provide me some references about this type of injection?

Thanks
