viewlib

A small library for Ebitengine for layered rendering and includes a basic camera implementation modified from ebiten-camera.

Layered rendering

var (
	cam *viewlib.Camera
)

func main() {
	ebiten.SetWindowSize(1366, 768)
	ebiten.SetWindowTitle("viewlib")

	if err := ebiten.RunGame(&Game{}); err != nil {
		log.Fatal(err)
	}
}

type Game struct {
}

func (g *Game) Layout(outsideWidth, outsideHeight int) (screenWidth, screenHeight int) {
	return outsideWidth, outsideHeight
}

func (g *Game) Update() error {

	return nil
}

func (g *Game) LayerRender(screen *ebiten.Image) {
	layer := 1
    viewlib.Draw(image.Image, viewlib.RenderModeWorld, layer).
        Position(100, 100).
        Rotation(float32(22.0)).
        Queue()
}

func (g *Game) Draw(screen *ebiten.Image) {
	viewlib.RenderTo(screen, cam)
}
