package main

// import the package
import (
    "github.com/franeklubi/tie"
)

func main() {
    // initialize engine in main
    tie.Init(500, 500, "window_name", false)
    //   width, height, window_name, is_resizable

    // pass all the functions you want used by the engine
    tie.PassFunctions(
        preload,
        setup,
        draw,
    )

    // launch the engine
    tie.Launch()
}

var (
    img tie.Image
)

// called only once, before setup, nothing can be drawn here
func preload() {
    img = tie.LoadImage("/path/to/image.png")
}

// called only once, before draw, you can draw here
func setup() {
    tie.Background(255, 255, 255, 255)
}

// called once every frame
func draw() {
    // drawing loaded image
    tie.Fill(255, 255, 255, 255)
    tie.PastePixels(img, 0, 0, tie.Width, tie.Height)

    // drawing ellipse
    tie.Fill(0, 255, 0, 255)
    tie.Ellipse(tie.Width/2, tie.Height/2, 200, 200)

    // drawing rectangle
    tie.Fill(0, 255, 255, 255)
    tie.Rect(tie.Width/2-50, tie.Height/2-50, 100, 100)
}
