Question

我有问题。我正在Unity 3D（c＃）做一个项目，这是一个3D世界编辑器。我的问题是我想通过选择它们来移动多个对象。我设法用我的鼠标光标移动一个，但是对于多个我失败了：D 这是我移动一个的代码：

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;是单 GameObject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)执行此操作：

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它变得非常简单。您现在可以调用objects.Add(newObject);添加对象，objects.Remove(oldObject);删除对象。
