Using Sprites to store transformations

As we saw from our last step, writing out the different transformations of an image can get pretty clunky pretty fast. The solution is to use Sprites, which combine a Texture and some transformations.

import dgt;

void main()
{
    Window window = Window("Your First Window", 800, 600, WindowConfig());
    Texture ball = Texture("ball.png");
    Sprite sprite = Sprite(ball);
    sprite.x = 400;
    sprite.y = 300;
    sprite.originX = ball.size.width / 2;
    sprite.originY = ball.size.height / 2;
    while(window.isOpen)
    {
        window.begin(Color.white);
        window.draw(sprite);
        sprite.rotation++;
        window.end();
    }
}

The new window should be identical to the last, with a spinning ball in the middle.

Sprite sprite = Sprite(ball); constructs a sprite using the ball texture.

Sprites have properties for each transform, so you can set the transformations without having to specify each one.
