制作3D旋轉(zhuǎn)動(dòng)畫(huà)效果Flash教程本教程著重于代碼的編寫(xiě)，版本AS3.0。只要制作一個(gè)旋轉(zhuǎn)的3D球，圖形元件的制作不作講解，請(qǐng)參看有關(guān)教程。?includeMath2.as?//圖片容器?varmenu:Sprite=newSprite();?//使圖標(biāo)移動(dòng)?menu.x=300;?menu.y=200;?//注冊(cè)事件偵聽(tīng)器?menu.addEventListener(Event.ENTER_FRAME,moveMenu);?this.addChild(menu);?//橢圓在x和y軸上的截距?vardisx:Number=200;?vardisy:Number=10;?//旋轉(zhuǎn)速度?varspeed:Number=0;?initMenu(5);?functioninitMenu(n:int){?for(vari:int;i?varmc:MovieClip=newIconMenu();?//縮小圖標(biāo)?mc.scaleX=mc.scaleY=.5;?menu.addChild(mc);?}?}?//事件偵聽(tīng)器函數(shù)?functionmoveMenu(e:Event):void{?//獲取圖標(biāo)數(shù)?variconCount:int=menu.numChildren;?//定義數(shù)組?vardepthArray:Array=newArray();?//把360度平分?varangle:Number=360/iconCount;?for(varz:int;z?//根據(jù)深度獲取圖標(biāo)?varmc:MovieClip=menu.getChildAt(z);?//跳轉(zhuǎn)到不同幀，來(lái)顯示不同的圖標(biāo)?mc.gotoAndStop(z+1);?//設(shè)置圖標(biāo)的位置?mc.x=cosD(speed+angle*z)*disx;?mc.y=sinD(speed+angle*z)*disy;?setProp(mc,alpha);?setProp(mc,scaleX,.2,.7);?setProp(mc,scaleY,.2,.7);?//保存圖標(biāo)到數(shù)組?depthArray[z]=mc;?}?//重新設(shè)置圖標(biāo)的深度?arrange(depthArray);?speed+=2;?}?functionarrange(depthArray:Array):void{?//按照y坐標(biāo)排序?depthArray.sortOn(y,Array.NUMERIC);?vari:int=depthArray.length;?while(i--){?menu.setChildIndex(depthArray[i],i);?}?}?functionsetProp(mc:MovieClip,prop:String,n1:Number=.5,n2:Number=1):void{?mc[prop]=((mc.y+2*disy)/disy-1)/2*(n2-n1)+n1;?}?5、新建.as文檔，保存名為：Math2.as(這個(gè)文檔是進(jìn)行三角函數(shù)的計(jì)算)?//角度轉(zhuǎn)弧度?functionangleToRadian(angle:Number):Number?{?returnangle*(Math.PI/180);?}?//弧度轉(zhuǎn)角度?functionradianToAngle(radian:Number):Number?{?returnradian*(180/Math.PI);?}?//計(jì)算正弦值?functionsinD(angle:Number):Number?{?returnMath.sin(angleToRadian(angle));?}?//計(jì)算余弦值?functioncosD(angle:Number):Number?{?returnMath.cos(angleToRadian(angle));?}?//計(jì)算反正切?functionatan2D(y:Number,x:Number):Number?{?returnr
