MC连线缓动(AS2.0)
[color=#000000][font=宋体]前一阵子看闪吧教材，[/font][font=宋体, MS Song]farewell[/font][font=宋体]老师做了一个名为“[/font][font=宋体, MS Song]MC[/font][font=宋体]连线缓动演示[/font][font=宋体, MS Song](AS2.0)[/font][font=宋体]”的教材，特受启发，自己也做了一个，跟老师唯一不一样的地方是缓动效果用的是内置类，效果见下：[/font][/color]

[font=宋体][color=#000000]其实做这个缓动跟老师的方法很一样，核心就在缓动的形成。下面一步一步的教大家制作：[/color][/font]
[color=#000000][font=Calibri][font=宋体, MS Song]1.[/font]
[/font][font=宋体]制作一个[/font][font=宋体, MS Song]MC[/font][font=宋体]，在[/font][font=宋体, MS Song]MC[/font][font=宋体]里画一个背景，新建图层，加入一个动态文本，命名为”[/font][font=宋体, MS Song]my_txt[/font][font=宋体]”，将[/font][font=宋体, MS Song]MC[/font][font=宋体]保存，命名为”[/font][font=宋体, MS Song]mc[/font][font=宋体]”，下面是制作时的截图：[/font][/color]

[color=#000000][font=Calibri][font=宋体, MS Song]2.[/font]
[/font][font=宋体]在库面板中右击鼠标，选择“链接”，将”[/font][font=宋体, MS Song]mc[/font][font=宋体]”链接为共享导出，截图如下：[/font][/color]
