Looks awesome! But is it for swift or c++? This here seems like scenekit or spritekit

So in other words, glTF is supported by the metal api regardless?

OK cool so I use this shown here and the virtual joystick will pop-up on the screen without me having to add any more code?

So, metal is what you had in mind? I'm using C++ to do graphic programming
