推薦：Flash Action實(shí)現(xiàn)小球沿不規(guī)則的路徑上移動(dòng)
用了BitmapData.getPixel();來做的.原理:路徑為一像素的純色的不規(guī)則的曲線(如紅色),用getPixel();記錄曲線上的所有坐標(biāo).importflash.display.BitmapData;im

先發(fā)效果，效果有參考一下國外的餅圖，不過他的代碼，注釋等我也看不懂，英文不懂，所以我就寫個(gè)中文的好了。大家完全可以根據(jù)我的代碼改出更多的效果來。
編程水平有限，大家諒解一下，不過能正常運(yùn)行。

數(shù)據(jù)來源于xml配置文件，可以直接修改xml文件以達(dá)到直接使用的目的。默認(rèn)數(shù)據(jù)來源為piedata.xml但是可以在頁面中修改這個(gè)數(shù)據(jù)來源。如下：
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="600" height="600">
<param name="movie" value="ok.swf?piedata=piedata.asp" />
<param name="quality" value="high" />
<embed src="ok.swf?piedata=piedata.asp" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="600" height="600"></embed>
</object>

在代碼中swf文件名后加上參數(shù)?piedata=piedata.asp則可以修改數(shù)據(jù)來源為piedata.asp。

其實(shí)原理也不難，先畫個(gè)圓（扇形）做上表面，然后分別畫出兩個(gè)側(cè)面和一個(gè)曲面，最后畫底下的圓（扇形）。一個(gè)立體的小扇形就出來了。讓他們一起拼在一起就成了餅圖嘛。只有一點(diǎn)比較煩就是確定每一個(gè)扇形的深度，好讓他們?cè)谝晫W(xué)上看起來處于正常的前后關(guān)系位置。在這兒，我想了一個(gè)法子。
先算出當(dāng)前扇形的中間度數(shù)，看這個(gè)度數(shù)是否在水平線以下，是的話就看這個(gè)度數(shù)與垂直方向的角度，角度最小的在最前面，最大的在最后面，假如中間度數(shù)在水平線以上，那么則與中間度數(shù)在水平線以下的相反。這兒要注重的是必須要從正上方作為0度，開始計(jì)算。

下面是源文件，所有代碼放到影片的時(shí)間軸上的一幀中就可以了。
