go-raylib

go-raylib

go-raylib is a simple and easy-to-use library to enjoy videogames programming.

Bindings

Platforms

Version

go-raylib binding raylib C 3.5 release version

Performance

High performance, same with the raylib C version.

Development Tools

I use sublime text and customize tools.

c-for-go automatic C-Go bindings generator for raylib C version.

LSP use mistune instead mdpopups.

language-formatter general code format tool.

gopls fix go-raylib code autocomplete slow.

Theme-Mariana general color scheme.

Memory

For example

multext := rl.NewMultiText([]string{"Hello World!"})

The method will check if memory is requested through cgo.

If it detects, panic Cgo memory alloced, please use func AllocMultiText.

Rewrite.

multext, men := rl.AllocMultiText([]string{"Hello World!"})
multext.GC(mem)

Don't forget, call GC() for register, it can be automated management.

Difference

There are some differences between the processing in Go and C.

In C

char multiTextBoxText[256] = "Multi text box";

In Go

multiTextBoxText := rg.NewBytes("Multi text box", 256)

In C

const char *listViewExList[8] = { "This", "is", "a", "list view", "with", "disable", "elements", "amazing!" };

In Go

listViewExList, mem := rg.AllocMultiText([]string{"This", "is", "a", "list view", "with", "disable", "elements", "amazing!"})
listViewExList.GC(mem)

In C

int dropsCount = 0;
char **droppedFiles = GetDroppedFiles(&dropsCount);
const char *droppedFilePath = droppedFiles[0];

In Go

dropsCount := int32(0)
droppedFiles := rl.GetDroppedFiles(&dropsCount)
droppedFilePath := rl.ToString(droppedFiles, 0)

In C

Texture2D texture = LoadTexture("resources/cubicmap_atlas.png");
model.materials[0].maps[MAP_DIFFUSE].texture = texture;

In Go

texture := rl.LoadTexture("../models/resources/cubicmap_atlas.png")
model.Materialser(0).Mapser(rl.MAP_DIFFUSE).Texture = texture

Usage

Step 1: Get the go-raylib code

go get -u github.com/chunqian/go-raylib

Step 2: Write the code

package main

import (
    rl "github.com/chunqian/go-raylib/raylib"

    "runtime"
)

func init() {
    runtime.LockOSThread()
}

func main() {
    screenWidth := int32(800)
    screenHeight := int32(450)

    rl.InitWindow(screenWidth, screenHeight, "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()
    }
}

Step 3: Build the code

Macos Linux

export GO111MODULE="on"
export CGO_ENABLED=1
go mod init github.com/chunqian/go-raylib-example
go build

Windows

set GO111MODULE=on
set CGO_ENABLED=1
set GOARCH=386
go mod init github.com/chunqian/go-raylib-example
go build

Require

MacOS

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

Windows

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

Ubuntu

sudo apt-get install libasound2-dev mesa-common-dev libx11-dev libxrandr-dev libxi-dev xorg-dev libgl1-mesa-dev libglu1-mesa-dev
