raylib

GoDoc GitHub release LLGo LLGo bindings XGo

LLGo bindings for raylib 6.0.0. The generated package exposes the public raylib.h API, camera helpers from rcamera.h, and raylib value types and constants. Functions that take a raylib struct as their first argument are available as methods where LLGo can represent that form.

Installation

Install LLGo, raylib, and pkg-config:

brew install raylib pkg-config

The binding links with pkg-config --libs raylib and therefore uses the raylib installation selected by your PKG_CONFIG_PATH.

Usage

package main

import (
	"github.com/goplus/lib/c"
	"github.com/llarhub/raylib"
)

func main() {
	raylib.InitWindow(800, 450, c.Str("raylib + LLGo"))
	defer raylib.CloseWindow()
	for !raylib.WindowShouldClose() {
		raylib.BeginDrawing()
		raylib.ClearBackground(raylib.RAYWHITE)
		raylib.EndDrawing()
	}
}

The package also supports headless data operations such as raylib.GenImageColor; call the generated Image.Unload method when an image is no longer needed.

Verification

Run the standard Go check and the LLGo tests from the repository root:

go test ./...
llgo test ./...

The LLGo test exercises image generation, resource release, generated constants, and value type layout. The binding is generated from the raylib headers installed on the build machine, so keep the raylib API version aligned with the headers and library used at link time.
