こんにちは。
CreateJS 開発スピードが一向に上がらない ひろゆき です。
今回は、ひよこちゃんの背景で雲を流すことに挑戦してみます。
それっぽくできるかな？

Piyo + Clouds [class] | CreateJS
背景との前後関係から、ひよこちゃんの配置タイミングを少し後にずらしてみた。
[追記] (2013.05.29.)
SoundJS の 0.4.1 へのバージョンアップに伴い、スクリプトを一部修正しました。
[追記] (2013.06.30.)
Ticker.addListener() は非推奨になっているようなので、書き換えました。
[追記] (2013.10.30.)
CreateJS を 0.7.0 にバージョンアップ。
Ticker.useRAF は非推奨になっているようなので、書き換えました。
