func RecordScreenAsGIF ¶

func RecordScreenAsGIF(update func(*ebiten.Image) error, out io.Writer, frameNum int) func(*ebiten.Image) error

RecordScreenAsGIF returns updating function with recording the screen as an animation GIF image.

This encodes each screen at each frame and may slows the application.

Here is the example to record initial 120 frames of your game:

func update(screen *ebiten.Image) error {
    // ...
}

func main() {
    out, err := os.Create("output.gif")
    if err != nil {
        log.Fatal(err)
    }
    defer out.Close()

    update := RecordScreenAsGIF(update, out, 120)
    if err := ebiten.Run(update, 320, 240, 2, "Your game's title"); err != nil {
        log.Fatal(err)
    }
}
