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 0.2.018

Raylib version: 5.5

Raygui version: 4.5-dev

There are also examples--direct Jai ports of the raylib examples.

There are more than shown here ported in the examples/ folder.

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

Run compile_examples.bat with jai on your PATH.

Run the example .exe files from the examples/ directory.

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.

Regenerating the bindings

jai .\generate.jai

(Optional) Regenerate raygui lib files

jai .\generate.jai - -g
