Hi,

I am looking for a little game prototypes / code snippets in SWI-Prolog.

The requirement is just:

1. A game loop, which calls a `update` every 0.016ms.

2. A `get_keyboard_state` like interface, which can get keyboard state (i.e. check a key state up/down).,

3. A graphics interface, which allow me to draw some squares in the canvas.

Since I have no prior experience for developing graphical interactive applications in Prolog, can anyone give me some guidance ? (code snippets / prototypes would be nice)

Very Thanks.

P.S. Performance is not necessary.

Thanks. I have not dig into these remarkable projects. It seems that they use web technology which is a bit difficult for me.

* * *

I am using [plOpenGL](https://www.swi-prolog.org/pack/list?p=plOpenGL).

 ![opengl](https://global.discourse-cdn.com/free1/uploads/swiprolog/original/2X/2/2d3498a4bbd7608bb5570bcb6600fdca56767699.jpeg)

Although it’s a bit weak compared to other mature game engines or multimedia libraries, I believe it’s a good starting point. It would be nice if SWI-Prolog can provide [SDL](https://www.libsdl.org/) bindings.

Other possible directions:

1. [gnuprolog-libsdl2](https://github.com/emacstheviking/gnuprolog-libsdl2)

2. [xpce](https://www.swi-prolog.org/packages/xpce/)

but I haven’t explored them yet.

P.s. Still waiting for better solutions.
