How to use SDL.RenderGeometry()

[CiBri0]

Hi,

I tried many times to run the SDL.RenderGeometry() function but I can’t.

In the third argument (vertices), I cannot convert my array containing my SDL::Vertex to FFI::Pointer or FFI::MemoryPointer.

I’m sorry for the inconvenience, plus I think the problem comes from me x)

I regret to say that I can't get what is your problem because there's no actual codes provided to reproduce your problem.

But once I used SDL.RenderGeometry without any problem in my game.

You can see a red circle near the mouse cursor, which is drawn by RenderGeometry.

So this code might help to understand the usage:
