raylib-zig

Manually tweaked, auto-generated raylib bindings for zig.

Bindings tested on raylib version 5.1-dev and Zig 0.13.0

Thanks to all the contributors for their help with this binding.

Example

const rl = @import("raylib");

pub fn main() anyerror!void {
    // Initialization
    //--------------------------------------------------------------------------------------
    const screenWidth = 800;
    const screenHeight = 450;

    rl.initWindow(screenWidth, screenHeight, "raylib-zig [core] example - basic window");
    defer rl.closeWindow(); // Close window and OpenGL context

    rl.setTargetFPS(60); // Set our game to run at 60 frames-per-second
    //--------------------------------------------------------------------------------------

    // Main game loop
    while (!rl.windowShouldClose()) { // Detect window close button or ESC key
        // Update
        //----------------------------------------------------------------------------------
        // TODO: Update your variables here
        //----------------------------------------------------------------------------------

        // Draw
        //----------------------------------------------------------------------------------
        rl.beginDrawing();
        defer rl.endDrawing();

        rl.clearBackground(rl.Color.white);

        rl.drawText("Congrats! You created your first window!", 190, 200, 20, rl.Color.light_gray);
        //----------------------------------------------------------------------------------
    }
}

Building the examples

To build all available examples simply zig build examples. To list available examples run zig build --help. If you want to run an example, say basic_window run zig build basic_window

Building and using

Using raylib-zig's template

In an existing project (e.g. created with zig init)

Download and add raylib-zig as a dependency by running the following command in your project root:

zig fetch --save https://github.com/Not-Nik/raylib-zig/archive/devel.tar.gz

Then add raylib-zig as a dependency and import its modules and artifact in your build.zig:

const raylib_dep = b.dependency("raylib-zig", .{
    .target = target,
    .optimize = optimize,
});

const raylib = raylib_dep.module("raylib"); // main raylib module
const raygui = raylib_dep.module("raygui"); // raygui module
const raylib_artifact = raylib_dep.artifact("raylib"); // raylib C library

Now add the modules and artifact to your target as you would normally:

exe.linkLibrary(raylib_artifact);
exe.root_module.addImport("raylib", raylib);
exe.root_module.addImport("raygui", raygui);

If you additionally want to support Web as a platform with emscripten, you will need to use emcc.zig by importing raylib-zig's build script with const rlz = @import("raylib-zig"); and then accessing its functions with rlz.emcc. Refer to raylib-zig's project template on how to use them.

Exporting for web

To export your project for the web, first install emsdk. Once emsdk is installed, set it up by running

emsdk install latest

Find the folder where it's installed and run

zig build -Dtarget=wasm32-emscripten --sysroot [path to emsdk]/upstream/emscripten

once that is finished, the exported project should be located at zig-out/htmlout

When is the binding updated?

I plan on updating it every mayor release (2.5, 3.0, etc.). Keep in mind these are technically header files, so any implementation stuff should be updatable with some hacks on your side.

What needs to be done?
