こんにちは。きんくまです。
この間のF-siteの用にflixelでつくった弾幕ゲームのデモを少し修正できたのでアップします。
デモのときは、iPadで使えるようにキーボード操作でなく、タッチ操作にしてました。
■あそびかた
キーボードの上下左右で操作。３回やられたらゲームオーバー。
クリアしてもループするだけです。すみません、、。
あれ？ ブラウザでみると、けっこうカクつきますね。
swfそのまま見ると、もうちっとなめらかなんだけど。
ソースコードも書いておきます。
flixelが面倒なことをやってくれてるので、わりと短め？なのかな。
自機爆発のビットマップデータはflixelについてたflixelのロゴデータですw
