Question

我正在尝试使用Unity3d创建类似jig-saw拼图的游戏我有两个gameObj，每个都有空的父gameObj，当我把它们（childObj）拖到彼此时它们互相粘在一起。我将两个ParentObj合并为一个，它有两个孩子（piece1 piece2）。如何将PolygonCollider2D从piece1和piece2添加到ParentObj？

void CombinePieces(Transform piece1, Transform piece2) {

        if (piece1.parent != null) {
            //Debug.Log (piece1.parent.name);
                if (piece2.parent != null) {

                //Destroy(piece2.parent, 3.0f);
                }

                piece2.parent = piece1.parent;


                //here should be created new PolygonCollider2D which should have PolygonCollider2D  
                //from piece1 and piece2

                piece2.collider2D.enabled = false;
                piece1.collider2D.enabled = false;

            }

            else {

                if (piece2.parent != null) {
                    piece1.parent = piece2.parent;
                }

                else {

                    Transform trans = new GameObject().transform;

                    piece1.parent = trans;
                    piece2.parent = trans;
                Debug.Log("6");

                }
            }
        }
}

您可以使用GameObject.AddComponent将组件添加到GameObject。

你可以做到 piece1.parent.gameObject.AddComponent<PolygonCollider2D>();

此函数还返回组件本身，如Unity文档中所述： http://docs.unity3d.com/ScriptReference/GameObject.AddComponent.html
