Unity 3D 脚本移动多个对象

Question

我有问题。我在 Unity 3D (c#) 中做一个项目，一个 3D 世界编辑器。我的问题是我想通过选择多个对象来移动它们。我设法用鼠标光标移动了一个，但是对于多个我失败了：D 这是我的移动代码：

public class ClickAndDrag : MonoBehaviour {
    private RaycastHit raycastHit;
    private GameObject Gobj;
    private float distance;
    private Vector3 ObjPosition;
    private bool Bobj;

    // Use this for initialization
    void Start() {
    }

    // Update is called once per frame
    void Update() {
        if (Input.GetMouseButton (0)) {
            var ray = GetComponent<Camera> ().ScreenPointToRay (Input.mousePosition);
            var hit = Physics.Raycast (ray.origin, ray.direction, out raycastHit);

            if (hit && !Bobj) {
                Gobj = raycastHit.collider.gameObject;
                distance = raycastHit.distance;
                Debug.Log (Gobj.name);
            }

            Bobj = true;
            ObjPosition = ray.origin + distance * ray.direction;
            Gobj.transform.position = new Vector3 (ObjPosition.x, ObjPosition.y, ObjPosition.z);
        } else {
            Bobj = false;
            Gobj = null;
        }       
    }
}

感谢您的帮助！

Answer 1

private GameObject Gobj; 是一个单个游戏对象的变量。将其重新格式化为 private List<GameObject> objects; 而不是 Gobj.transform.position = new Vector3 (ObjPosition.x, ObjPosition.y, ObjPosition.z) 这样做：

foreach (GameObject item in objects)
{
    item.transform.position = new Vector3 (ObjPosition.x, ObjPosition.y, ObjPosition.z)
}

编辑：如果您不确定如何操作列表，List<T> 有一组内置函数可以让操作变得非常简单。您现在只需调用objects.Add(newObject); 添加对象，调用objects.Remove(oldObject); 删除对象。
