raylib-go

Golang bindings for raylib, a simple and easy-to-use library to enjoy videogames programming.

raylib C source code is included and compiled together with bindings. Note that the first build can take a few minutes.

It is also possible to use raylib-go without cgo (Windows only; see requirements below).

Requirements

Ubuntu

apt-get install libgl1-mesa-dev libxi-dev libxcursor-dev libxrandr-dev libxinerama-dev libwayland-dev libxkbcommon-dev

Fedora

dnf install mesa-libGL-devel libXi-devel libXcursor-devel libXrandr-devel libXinerama-devel wayland-devel libxkbcommon-devel

macOS

On macOS you need Xcode or Command Line Tools for Xcode.

Windows

cgo

On Windows you need C compiler, like Mingw-w64 or TDM-GCC. You can also build binary in MSYS2 shell.

To remove console window, build with -ldflags "-H=windowsgui".

purego (without cgo, i.e. CGO_ENABLED=0)

Download the raylib.dll from the assets on the releases page. It is contained in the raylib-*_win64_msvc*.zip. Put the raylib.dll into the root folder of your project or copy it into C:\Windows\System32 for a system-wide installation.

As of November 15, 2023, raylib 5.0 is the required version.

It is also possible build the dll yourself. You can find more infos at raylib's wiki.

Android

Android example.

Installation

go get -v -u github.com/gen2brain/raylib-go/raylib

Build tags

• drm - build for Linux native DRM mode, including Raspberry Pi 4 and other devices (PLATFORM_DRM)
• sdl - build for SDL backend instead of internal GLFW (PLATFORM_DESKTOP_SDL)
• noaudio - disables audio functions
• opengl43 - uses OpenGL 4.3 backend
• opengl21 - uses OpenGL 2.1 backend (default is 3.3 on desktop)
• opengl11 - uses OpenGL 1.1 backend (pseudo OpenGL 1.1 style)
• es2 - uses OpenGL ES 2.0 backend (can be used to link against Google's ANGLE)

Example

package main

import rl "github.com/gen2brain/raylib-go/raylib"

func main() {
	rl.InitWindow(800, 450, "raylib [core] example - basic window")
	defer rl.CloseWindow()

	rl.SetTargetFPS(60)

	for !rl.WindowShouldClose() {
		rl.BeginDrawing()

		rl.ClearBackground(rl.RayWhite)
		rl.DrawText("Congrats! You created your first window!", 190, 200, 20, rl.LightGray)

		rl.EndDrawing()
	}
}

Cross-compile (Linux)

To cross-compile for Windows install MinGW toolchain.
