教你用FLASH制作漂亮的图形旋转动画效果

本教程是向大家介绍利用FLASH制作漂亮的图形旋转动画效果，采用代码实现特效，对于编程人员非常适合学习，转发过来，希望大家喜欢！

效果：

代码如下：

复制代码var pMaxSize:Number = 150;
var pCenterX:Number = 275;
var pCenterY:Number = 200;
var pNumTraces:Number = 20;
var pNumLayers:Number = 30;
var pCurrentLayer:Number = 0;
var pLineColour:Number;
var pPointDegree:Array = new Array();
var pPointDegreeChange:Array = new Array();
var pPointScale:Array = new Array();
var pPointScaleChange:Array = new Array();
var pPointX:Array = new Array();
var pPointY:Array = new Array();
var pBaseTimeline:MovieClip;
var pIntervalId:Number;
function init(baseTimeline:MovieClip):Void {
pBaseTimeline = baseTimeline;
pBaseTimeline.createEmptyMovieClip("holder", 0);
for (var j:Number = 0; j<pNumLayers; j++) {
pBaseTimeline.createEmptyMovieClip("layer"+j, j+1);
pBaseTimeline["layer"+j]._x = pCenterX;
pBaseTimeline["layer"+j]._y = pCenterY;
}
initTraces();
pBaseTimeline.holder.onEnterFrame = function() {
moveSpheres();
};
pIntervalId = setInterval(this, "updateSeeds", 2000);
}
function initTraces() {
for (var i:Number = 0; i<pNumTraces; i++) {
pPointX = 0;
pPointY = 0;
pPointDegree = (6.28318530718/pNumTraces)*i;
pPointScale = 50;
}
updateSeeds();
for (i=0; i<pNumTraces; i++) {
plotLine(i);
}
}
function moveSpheres() {
for (var i:Number = 0; i<pNumTraces; i++) {
pPointDegree += pPointDegreeChange;
pPointScale += pPointScaleChange;
