GOGAME

This is a simple 2D game library for Go. It's incomplete and I'm writing it for my personal projects. Feel free to suggest features!!

Documentation

Once you have installed the package, just run:

go doc github.com/pnegre/gogame | less
go doc github.com/pnegre/gogame/sprite | less
go doc github.com/pnegre/gogame/cache | less

Usage

Simple example:

package main

import (
    "github.com/pnegre/gogame"
    "github.com/pnegre/gogame/cache"
    "github.com/pnegre/gogame/sprite"
    "log"
    "runtime"
)

const (
    WINTITLE = "test"
    WIN_W    = 800
    WIN_H    = 600
    IMAGE    = "sprite.png"
)

type Target struct {
    *sprite.Simple
}

func NewTarget() *Target {
    tex := cache.GetTexture(IMAGE)
    s := sprite.NewSimple(tex)
    s.Rect.SetCenter(WIN_W/2, WIN_H/2)
    return &Target{s}
}

func (self *Target) Update() {
    if gogame.IsKeyPressed(gogame.K_LEFT) {
        self.Rect.X -= 10
    }
    if gogame.IsKeyPressed(gogame.K_RIGHT) {
        self.Rect.X += 10
    }
    if gogame.IsKeyPressed(gogame.K_UP) {
        self.Rect.Y -= 10
    }
    if gogame.IsKeyPressed(gogame.K_DOWN) {
        self.Rect.Y += 10
    }
}

func main() {
    runtime.LockOSThread()
    if err := gogame.InitSDL(); err != nil {
        log.Fatal(err)
    }
    if err := gogame.Init(WINTITLE, WIN_W, WIN_H); err != nil {
        log.Fatal(err)
    }
    defer gogame.Quit()
    defer cache.DestroyAll()

    target := NewTarget()

    for {
        if quit := gogame.SlurpEvents(); quit == true {
            break
        }

        target.Update()

        gogame.RenderClear()
        target.Draw()
        gogame.RenderPresent()

        gogame.Delay(16)
    }

}
