Actionscript - 在我執行removeChild（）並重新添加addChild（）後，MC繼續移動

我有一個MC，鼠標可以拖動和滑動，當它從舞臺上移開時，它碰到超出邊界的對象。我將它添加到最初開始的x，y位置的舞臺上，但是當我重新添加它時，它會繼續沿着它在去除之前的方向滑動。Actionscript - 在我執行removeChild（）並重新添加addChild（）後，MC繼續移動

功能__checkHit（$ EVT：事件）：無效{

if (this.test_object.hitTestObject(bounds1)) 
{ 
    // do our in-circle check 
     stopDrag(); 
     removeChild(test_object); 
test_object.x = 437.25; 
test_object.y = 808.3; 
addChild(test_object);
