import * as Gejmko from 'gejmko/src';

const viewport = new Gejmko.Viewport('game-id-element');
viewport.init();
viewport.changeSize(300, 300);
viewport.changeBorder(new Gejmko.Border(1, 'black', 'solid'));

const game = new Gejmko.Game(viewport);
game.start();

class Circle extends Gejmko.AbstractEntity {
  x = 100;
  y = 75;

  render(): void {
    this.context.beginPath();
    this.context.arc(this.x, this.y, 50, 0, 2 * Math.PI);
    this.context.stroke();
  }

  update(): void {
    if (this.x - 50 >= 305) {
      this.x = -55;
      return;
    }

    this.x += 1;
  }
}

class MarioSprite extends Gejmko.Sprite {
  constructor() {
    super('assets/mario-sprite.png', 2, 16, 18, 3, 0, 0, 1);
  }

  update(): void {
    if (this.currentFrameNumber % 20 !== 0) {
      return;
    }

    super.update();
  }
}

game.addEntity(new MarioSprite());
game.addEntity(new Circle());
