package 
{
       import flash.display.Sprite;
       import flash.events.Event;
       import flash.utils.Timer;
       import flash.events.TimerEvent;
       import flash.text.TextField;
       
       public class Main extends Sprite 
       {
              public var dongTimer:Timer= new Timer(30);     
              public var first:TextField=new TextField();
              public function Main():void 
              {
                     dongTimer.addEventListener(TimerEvent.TIMER, yidong);
                     first.text = "FL部落";
                     first.textColor = 0x000000;
                     addChild(first);
                     first.x = 50;
                     first.y = 250;
                     dongTimer.start();  ;                    
              }            
              private function yidong(e:TimerEvent):void {
                     first.x += 10;
              }
       }
       
}
2、  到指定点的减速运动：位移=（终点-当前点）* 缓动比
package 
{
       import flash.display.Sprite;
       import flash.events.Event;
       import flash.utils.Timer;
       import flash.events.TimerEvent;
       import flash.text.TextField;
       
       public class Main extends Sprite 
       {
              public var dongTimer:Timer= new Timer(30);
              public var huanDu:Number = 0.1;
              public var stopPoint:Number = 500;
              public var first:TextField=new TextField();
              public function Main():void 
              {
                     dongTimer.addEventListener(TimerEvent.TIMER, yidong);
                     first.text = "FL部落";
                     first.textColor = 0x000000;
                     addChild(first);
                     first.x = 50;
                     first.y = 250;
                     dongTimer.start();
              }            
              private function yidong(e:TimerEvent):void {
                     first.x += (stopPoint - first.x) * huanDu;
              }
       }
       
}
3、鼠标跟随：位移=（鼠标位置-当前坐标）*缓动系数
package 
{
       import flash.display.Sprite;
       import flash.events.Event;
       import flash.utils.Timer;
       import flash.events.TimerEvent;
       import flash.text.TextField;
       
       public class Main extends Sprite 
       {
              public var dongTimer:Timer= new Timer(30);
              public var huanDu:Number = 0.1; 
              public var first:TextField=new TextField();
              public function Main():void 
              {
                     dongTimer.addEventListener(TimerEvent.TIMER, yidong);
                     first.text = "FL部落";
                     first.textColor = 0xFF0000;
                     addChild(first);
                     first.x = 50;
                     first.y = 250;                
                     dongTimer.start();                
              }            
              
              private function yidong(e:TimerEvent):void {
                     first.x += (mouseX-first.x) * huanDu;
                     first.y += (mouseY-first.y) * huanDu;                 
              }
       }
       
}

4、根据鼠标位置围绕一个点移动：
鼠标方向：位移=（（鼠标位置-中心点坐标）*范围系数-(当前坐标-中心点坐标) )*缓动系数
鼠标反方向：位移=（(当前坐标-中心点坐标)-（鼠标位置-中心点坐标）*范围系数)*缓动系数

package 
{
       import flash.display.Sprite;
       import flash.events.Event;
       import flash.utils.Timer;
       import flash.events.TimerEvent;
       import flash.text.TextField;
       
       public class Main extends Sprite 
       {
              public var dongTimer:Timer= new Timer(30);
              public var huanDu:Number = 0.1;
              public var fanWei:Number = 0.4;
              public var fanWei2:Number = 0.2;
              public var stopPoint_x:Number = 350;
              public var stopPoint_y:Number = 300;
              public var first:TextField=new TextField();
              public var last:TextField=new TextField();
              public function Main():void 
              {
                     dongTimer.addEventListener(TimerEvent.TIMER, yidong);
                     first.text = "FL部落";
                     first.textColor = 0xFF0000;
                     addChild(first);
                     first.x = 50;
                     first.y = 250;
                     last.text = "FL部落";
                     last.textColor = 0x999999;
                     addChild(last);
                     last.x = 800;
                     last.y = 100;
                     
                     dongTimer.start();
                     
              }            
              
              private function yidong(e:TimerEvent):void {
                     first.x += ((mouseX - stopPoint_x) * fanWei -(first.x - stopPoint_x)) * huanDu;
                     first.y += ((mouseY - stopPoint_y) * fanWei - (first.y - stopPoint_y)) * huanDu;
                     last.x -= ((mouseX - stopPoint_x) * fanWei2 + (last.x - stopPoint_x)) * huanDu;
                     last.y -= ((mouseY -  stopPoint_y) * fanWei2 + (last.y -  stopPoint_y)) * huanDu;
              }
       }
       
}
