Star Wars書いてみた

えーセルオートマトンがそもそも分かってないですがStar Wars書いてみた。

ルールはこちらの説明オンリーで作らせていただきましたありがとうございます。

動きはこちらを見て確認させていただきましたありがとうございます。
セルオートマトンを用いたシューティングゲーム - Tosikの雑記

動いているのを見てて楽しいですね。デフラグずっと見ちゃう的ですね。

実装はIronPython+XNAでやろうと思ったんだけどTexture2Dでのべた矩形がなぜが出なくて。
なので普通にC#+XNAになってます。しかしC#でも同意のコード書いてんのになんで出ないんだ。
