raylib-jai bindings

Raylib is a minimal gamedev library for C and this repository has a script for automatically generating Jai bindings from raylib.h, raymath.h, rcamera.h, rlgl.h and raygui.h.

Tested with Jai version: beta 0.2.025

Raylib version: 5.5

Raygui version: 4.5-dev

Features

• Windows, linux and macos support

• Raygui support

• Some functions which take enum arguments (like SetConfigFlags for example) have their argument types changed from C's int (or Jai's s32) to the actual enum type. Consequently, you can call them like SetConfigFlags(.FLAG_FULLSCREEN_MODE);

• An additional set of macros lets you change any of the Begin/End function call pairs (like BeginMode3D(camera) and EndMode3D()) into an equivalent PushMode3D(camera) which will insert an automatic defer EndXXX() call into the scope for you.

Examples

Direct Jai ports for the following:

• raylib examples
• raylib games

There are more than shown here ported in the examples/ and games/ folders.

Minimal example

Copy raylib directory into your libs directory. For example:

my_game/

.... libs/

.... .... raylib

.... main.jai

// main.jai
#import "raylib";

main :: () {
    InitWindow(800, 450, "raylib example");
    defer CloseWindow();

    while !WindowShouldClose() {
        BeginDrawing();
        defer EndDrawing();

        ClearBackground(RAYWHITE);
        DrawText("raylib + jai", 190, 200, 20, LIGHTGRAY);
    }
}

Compile using (on Windows): jai -import_dir .\libs .\main.jai

Building the examples

jai compile_examples_and_games.jai

Regenerating the bindings

(Optional) Regenerate raygui lib files
