会跳舞的骨骼小人[1]

既然这个小人可以画出来，那么可否让他动呢，我想这个很显然是没有问题的，只要把的身体的各个组成部分分解开就可以了。
组成这个小人的只有两种组件成分，一个是圆形，一个是线条.
代码分别如下:
class skelectonCircle
{
       private var x:Number=0;
       private var y:Number=0;
       private var r:Number=0;
       private var lineStyleNum:Number=0x3399FF;
       
       static private var mId:Number=0;
       private var mMcHolder:MovieClip;
              
       public function skelectonCircle(inX:Number,inY:Number,inR:Number,inStyle:Number)
       {
              init(inX,inY,inR,inStyle);
       }
       
       public function init(inX:Number,inY:Number,inR:Number,inStyle:Number):Void
       {
              reset(inX,inY,inR,inStyle);
              
              mMcHolder=_root.createEmptyMovieClip("__SKELETONC__"+mId,_root.getNextHighestDepth());
              mId++;
       }
       
       public function reset(inX:Number,inY:Number,inR:Number,inStyle:Number):Void
       {
              x=inX;
              y=inY;
              r=inR;
              
              if(inStyle!=null||inStyle!=undefined)lineStyleNum=0x3399FF;
              else lineStyleNum=inStyle;
       }
       
       public function draw():Void
       {
              //draw a cicle:        
                     mMcHolder.lineStyle(1,lineStyleNum,100);
                     //beginFill(0x6666FF);
                     //move to the circle’s center.
                     mMcHolder.moveTo(x+r,y);
                     
                     var fi:Number=0;
                     var cX:Number=0;
                     var cY:Number=0;
                     var detaFi:Number=0.1;
                     
                     while(fi<=2*Math.PI+0.2)
                     {
                            cX=x+r*Math.cos(fi);
                            cY=y+r*Math.sin(fi);
                            mMcHolder.lineTo(cX,cY);
                            fi+=detaFi;
                     }
                     //endFill();
       }
       
       public function clean():Void
       {
              mMcHolder.clear();
       }
       
       public function toString():String
       {
              var reString:String=new String();
              
              reString=String("x:"+String(x)+"y:"+String(y)+"r:"+String(r)+"\n");
              
              return reString;
       }
       
       public function finallize():Void
       {
              mMcHolder.removeMovieClip();
              mMcHolder=null;
              delete this;
       }
}

class skelectonLine
{
       private var x1:Number=0;
       private var y1:Number=0;
       
       private var x2:Number=0;
       private var y2:Number=0;
       
       private var lineStyleNum:Number=0x3399FF;
       
       static private var mId:Number=0;
       private var mMcHolder:MovieClip;
       
       //static private var thisP:Object;
       
       public function skelectonCircle(inX1:Number,inY1:Number,inX2:Number,inY2:Number,inStyle:Number)
       {
              init(inX1,inY1,inX2,inY2,inStyle);
       }
       
       public function init(inX1:Number,inY1:Number,inX2:Number,inY2:Number,inStyle:Number):Void
       {
              reset(inX1,inY1,inX2,inY2,inStyle);
              
              mMcHolder=_root.createEmptyMovieClip("__SKELETONL__"+mId,_root.getNextHighestDepth());
              mId++;
              
              //thisP=this;
       }
       
       public function reset(inX1:Number,inY1:Number,inX2:Number,inY2:Number,inStyle:Number):Void
       {
              x1=inX1;
              y1=inY1;
              
              x2=inX2;
              y2=inY2;
              
              if(inStyle!=null||inStyle!=undefined)lineStyleNum=0x3399FF;
              else lineStyleNum=inStyle;
       }
       
       public function draw():Void
       {
              //draw a line:
              mMcHolder.lineStyle(1,lineStyleNum,100);
              mMcHolder.moveTo(x1,y1);
              mMcHolder.lineTo(x2,y2);
              
       }
       
       public function clean():Void
       {
              mMcHolder.clear();
       }
       
       public function toString():String
       {
              var reString:String=new String();
reString=String("x1:"+String(x1)+"y1:"+String(y1)+"x2:"+String(x2)+"y2:"+String(y2)+"\n");
              return reString;
       }
       
       public function finallize():Void
       {
              mMcHolder.removeMovieClip();
              mMcHolder=null;
              delete this;
       }
}

接着，我们定义一个小人类,一共有11个部分组成，具体是什么你一看便知:

class skelectonPerson
{
       public var mHead:skelectonCircle;
       
       public var mLeftShoulder:skelectonLine;
       public var mRightShoulder:skelectonLine;
       
       public var mUpBody:skelectonLine;
       public var mDownBody:skelectonLine;
       
       public var mLeftHand:skelectonLine;
       public var mRightHand:skelectonLine;
       
       public var mLeftThigh:skelectonLine;
       public var mRightThigh:skelectonLine;
       
       public var mLeftLeg:skelectonLine;
       public var mRightLeg:skelectonLine;
       
       public function skelectonPerson()
       {
              mHead=new skelectonCircle();
              mLeftShoulder=new skelectonLine();
              mRightShoulder=new skelectonLine();
              mUpBody=new skelectonLine();
              mDownBody=new skelectonLine();
              mLeftHand=new skelectonLine();
              mRightHand=new skelectonLine();
              mLeftThigh=new skelectonLine();
              mRightThigh=new skelectonLine();
              mLeftLeg=new skelectonLine();
              mRightLeg=new skelectonLine();
       }
       
       public function draw():Void
       {
              mHead.draw();
              mLeftShoulder.draw();
              mRightShoulder.draw();
              mUpBody.draw();
              mDownBody.draw();
              mLeftHand.draw();
              mRightHand.draw();
              mLeftThigh.draw();
              mRightThigh.draw();
              mLeftLeg.draw();
              mRightLeg.draw();
       }
       
       public function clean():Void
       {
              mHead.clean();
              mLeftShoulder.clean();
              mRightShoulder.clean();
              mUpBody.clean();
              mDownBody.clean();
              mLeftHand.clean();
              mRightHand.clean();
              mLeftThigh.clean();
              mRightThigh.clean();
              mLeftLeg.clean();
              mRightLeg.clean();
       }
}

然后就是将这个小人的各个部分组装起来了:

var testPerson:skelectonPerson=new skelectonPerson();
testPerson.mHead.init(180,30,20);
testPerson.mLeftShoulder.init(140,80,180,80);
testPerson.mRightShoulder.init(180,80,220,80);
testPerson.mLeftHand.init(110,40,140,80);
testPerson.mRightHand.init(250,40,220,80);
testPerson.mUpBody.init(180,50,180,80);
testPerson.mDownBody.init(180,80,180,120);
testPerson.mLeftThigh.init(180,120,150,150);
testPerson.mRightThigh.init(180,120,210,150);
testPerson.mLeftLeg.init(150,150,150,200);
testPerson.mRightLeg.init(210,150,210,200);

最后，让我们以一个小人的手在挥动的动作来结束实验1:
感觉这个实验里最让我头痛的就是Flash正切角的计算方式了，搞了半天才算ok,呵呵~~: )
