Actionscript 3 如何在圆形轨道中对齐电影唇?

Actionscript 3 如何在圆形轨道中对齐电影唇?,actionscript-3,Actionscript 3,as3中电影唇的圆形对齐? 我在以圆形方式移动和对齐movieclips时遇到问题 for(var i:int;i<15;i++) { var obj:mc = new mc(); obj.scaleX = obj.scaleY = 0.5; this.addChild(obj); obj.gotoAndStop(i); obj.centerX = 372.3; obj.centerY = stage.stageHeight/2;

as3中电影唇的圆形对齐? 我在以圆形方式移动和对齐movieclips时遇到问题

for(var i:int;i<15;i++)
{
    var obj:mc = new mc();
    obj.scaleX = obj.scaleY = 0.5;
    this.addChild(obj);

    obj.gotoAndStop(i);

    obj.centerX = 372.3;
    obj.centerY = stage.stageHeight/2;

    //for tilt objects 
    //obj.angle = 200 - i*36;

    obj.angle = i*24; //for spaceing objects 36 for 10;
    obj.radius = 300;
    itemArray.push(obj);
}
allign();

for(var i:int;i使用三角方程相对于中心定位您的电影嘴唇

解决方案

          //Suppose the point center c={x:0, y:0}, and radius constant r=100;

          // define  pool of data type Vector for your Items(MovieClips)
          var objectPool:Vector.<Item>=new Vector.<Item>();

          //generate pool for your items and add them around the center

            var numItems:int=4;

            var angle:Number=360/numItems;

           //suppose you have a custom class ClipItem as a blue print for your clips
            var clipItem:ClipItem;

            var _x:Number, _y:Number;

             for(var i:int=0; i<numItems)
             {
                clipItem=new ClipItem;

                _x=c.x+Math.sin(angle)*r;
                _y=c.y+Math.cos(angle)*r;

                clipItem.x=_x; clipItem.y=_y;

                angle+=angle;
               //You might need reference to the clips for other interactions
               // such as moving them around. putting them in one place is ideal.
               objectPool.push(clipItem);
             }
//假设点中心c={x:0,y:0},半径常数r=100;
//为项目定义数据类型向量池(MovieClips)
变量对象池:向量。=新向量。();
//为您的项目生成池并围绕中心添加它们
变量numItems:int=4;
变量角度:数值=360/numItems;
//假设您有一个自定义类ClipItem作为剪辑的蓝图
var-clipItem:clipItem;
变量x:Number,变量y:Number;

for(var i:int=0;ifunction allign(){for(var i:int;i可能是相关的:请记住,
sin
cos
需要弧度而不是度作为参数。因此,
angle
应该实例化为
var angle:Number=(360/numItems)*Math.PI/180
