推薦：Flash問(wèn)答：一個(gè)簡(jiǎn)單的字母順序變化效果
問(wèn)：我設(shè)定一個(gè)動(dòng)態(tài)文本框var=zimu，我想讓它不停的按順序顯示A-Z26個(gè)字母，然后當(dāng)顯示到指定T時(shí)，則停止下來(lái)。這個(gè)效果用AS怎么寫��？（終極討厭）答：

　　前幾天的一篇文章，用Flash輕松制作電子發(fā)散視覺(jué)效果動(dòng)畫好多人都問(wèn)有什么用？今天就再繼續(xù)一下！看看紅外線引導(dǎo)導(dǎo)彈爆炸效果。

　　爆炸的代碼我們還使用前面那個(gè)教程中用到的代碼，在這個(gè)效果里，我們首先把光標(biāo)的外形變換一下，然后點(diǎn)鼠標(biāo)就有一個(gè)導(dǎo)彈出現(xiàn)，然后發(fā)生爆炸。

　　先看效果：（點(diǎn)擊鼠標(biāo)可以看到效果）

　　新建立一個(gè)文件，按Ctrl J調(diào)整大小和背景色(#999999)和幀頻。

　　然后制作一個(gè)紅色的小圓影片剪輯作為鼠標(biāo)的外形，制作一條有色的線條影片剪輯作為導(dǎo)彈，然后再制作一個(gè)白色小圓作為爆炸的影片剪輯。

　　然后在第一幀加入如下代碼。
