Riot.jsでゲームを作る

Posted at

この記事は Riot.js Advent Calendar 2016 の最終日の記事です。ギリギリの更新ですみません;

ゲームにも使えるRiot.js

Riot.js、いいですよね。
実用的なアプリで利用されている印象ですが、ゲーム開発にも便利に使えそうだと感じたので、試しに使ってみました。

とりあえず3Dっぽい迷路をうろうろするゲームを作ってみましたが、1フレーム単位でシビアなタイミングが要求されるゲームでなければ非常に実用的だと思います。

デモは↓こちら。
Plunkerでのデモ
壁にぶつかったときのOUCHは譲れないポイント

簡単な解説

  • 迷路データ(0:通路、1:壁、など)を配列に格納
  • 移動用のボタンを用意し、押下時に現在地データ(座標と方角)を書き換え
  • 現在地データと迷路データをもとに、迷路画像などの表示を切り替え
  • Plunker便利(Riot.js関係ない)

ソース

やっつけ感漂うソースですみません。特にsetToViewファンクションのベタベタ感が……。
