我一般不使用addchild。我发现代码和我试图在鼠标按下时创建一个圆圈，我尝试碰撞其他球。 所以我可以用鼠标创造球，但我没有碰到其他球。

答案 0 :(得分：2)
使用addChild，您只是将新创建的圆圈添加到舞台中，以便绘制它。您还需要将其耦合到处理球碰撞的逻辑。
需要更新变量NUMBER_OF_CIRCLES以表示新的圈数。您还需要将新圆圈（及其circle_update函数中所需的所有值）添加到circle_array数组，以便每帧更新圆圈的位置。此更新在circle_update函数中执行。因此，请使用以下代码替换您创建mcKall的代码部分：
if(drag==false && mouseuo==true){
var i:Number = NUMBER_OF_CIRCLES;
NUMBER_OF_CIRCLES+=1;
circle_array[i] = new circle();
circle_array[i].width = the_kall.width;
circle_array[i].height = circle_array[i].width;
circle_array[i].x = the_kall.x;
circle_array[i].y = the_kall.y;
var myColor:ColorTransform = this.transform.colorTransform;
myColor.color = 0x000077 * Math.random() + 0x000088;
circle_array[i].inner.transform.colorTransform = myColor;
addChild(circle_array[i]);
circle_array[i].id = i;
vector_array[i] = new Array(0,0);
mass_array[i] = circle_array[i].width * 0.10;
removeChild(the_kall)
}
为了将来参考，请务必发布可读的代码。这包括格式化代码和命名变量，以便它有意义。像zamzam这样的变量名让其他人更难帮助你，因为他们更难理解你的代码。
