RandomTextを作ってみた。
RandomTextを作ってみた。
* こういうのをRandomText,RandomTypo,TextSlotなどと呼ぶらしい。
* twitterで教えてくれた方々、ありがとう。
*
* いろいろ設定できるように作ったつもりだけど、
* align = 'right'/'center'と、
* tween対応をしていない。
* 日本語の時に2byteとして、とかもやってない。
* まあ、そのうち。
*
*
* private var obj:Object = { cursor:"" , random:true, randomNum: -1, defoltText:"" , targetText:"", delay:0, speed:1 };
*
* 【参考】
