Functions

func DebugPrint

func DebugPrint(image *ebiten.Image, str string) error

DebugPrint draws the string str on the image.

DebugPrint always returns nil as of 1.5.0-alpha.

func NewImageFromFile

func NewImageFromFile(path string, filter ebiten.Filter) (*ebiten.Image, image.Image, error)

NewImageFromFile loads the file path and returns ebiten.Image and image.Image.

The current directory for path depends on your environment. This will vary on your desktop or web browser. Note that this doesn't work on mobiles. It'll be safer to embed your resource, e.g., with github.com/jteeuwen/go-bindata instead of using this function.

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)
    }
}
