2章スプライトの描画
アプリケーションを動かし画面に描画できるようになったので、ゲームのように見える「何か」を作れるようになった。次は「スプライトの描画」を行おう。スプライトを描画する、ということは要するに画面上に絵を表示するということだ。本章では、まず少しだけゲームのデザインを行ってから、描画する絵を定義して静止したスプライトとしてスクリーン上に表示する。動かない絵を表示するだけではあまりにも退屈なゲームになってしまうので、さらにスプライトのアニメーションも行う。
本章では以下のことを行う。
- ゲーム「Walk the Dog （犬の散歩）」のデザイン
- Canvasへのスプライトの描画
- スプライトシートを用いた複数スプライトのロード
- スプライトシートを用いたキャラクターアニメーション
本章を読み終える頃には、動かない三角形ではなくキャラクターを描画できるようになり、さらにキャラクターをスクリーン上で走らせることができるようになる。
