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 (if you have brew installed, you already have this).

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.

It is also possible to build the DLL yourself. You can find more info at raylib's wiki.

Android

Android example.

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()
	}
}
