I would like to develop my own UI for GTA V just like there is already a NativeUI.dll which you can build menus etc. I would like to build a UI my own.
I don't want to create something like NativeUI, I want something more unique like a form or window which you can open in-game (with buttons, a closing X and labels, switches etc.).
Is it possible to create something like this? And how to do this? I know it is possible to draw rectangles and shapes but I don't know if it is the best practice to build a window with that elements.. Also if I want buttons and on/off switches I would like to do this myself.
Is there any documentation to use elements which I can build my own in-game window or does someone know how to build it?
Thanks in advance
