Sorry bout the misunderstanding, but yeah problem still stands. I can't help you without your original code. I think I fixed it. I was initializing SDL_Rects to nulls inside some of the arguments. It was a slight case of Spaghetti Code. Oh well, thank you for your time.

You need a pointer to renderTarget.

I actually have a pointer in the original project but I seem to

It works with no problem. I've DerelictSDL2.load and SDL_Init

So is this a bug or am I doing something wrong here?
