 [Flash][讨论] 求助]请问有关翻页按钮的问题
小弟学习翻书的flash特效遇到了瓶颈希望哪位大大能赐教一下感激万分
以下是程式码
小弟想要在翻书的页面上增加点选页面数字的按钮 然后即可自动翻到那一页的功能
但是最下面的描述看不懂 他说加入
-------------------
gotoPage( destinationPageNo ); //quick jump to the page number: destinationPageNo;
values = 0-maxpages;
autoflip(); //start autoflip (direction is calculated from _xmouse)
canflip //it's a variable. setting its value to false disables flipping
other functions of page turning is automatic;
-----------------------
我有复制过gotoPage autoflip(); canflip values = 0-maxpages;
但是各种方式贴在按钮上 执行出来 点到页数都无法自动翻页 苦恼了很久
希望哪位大大能帮小弟一下
