Question

我正在使用Unity 3D开发Vuforia AR应用程序。我想基于UI操作更改使用其他模型进行扩充的模型。

以下代码正常运行。请参阅附带的屏幕截图在筹码目标牛和＆amp;大象模特正在展示。我将ModelSwapper脚本拖到ARCamera，在Inspector视图中我选择了cow。当我运行应用程序时，单击按钮，牛已经消失。它工作正常。第二个屏幕截图柏油碎石机显示牛和＆amp;大象模型。在检查员，我该怎么办？我需要在点击按钮的同时移除大象。我需要为tarmac创建另一个脚本吗？

 using UnityEngine;

    using System.Collections;


   public class ModelSwapper : MonoBehaviour {

   // public TrackableBehaviour theTrackable;

  private GameObject theTrackable;

  private GameObject cube;

     private bool mSwapModel = false;

     public Transform MyPrefab;



    // Use this for initialization

    void Start () {

   theTrackable=GameObject.Find("Cow");
    cube = GameObject.Find("Cow");

  if (theTrackable == null)

            {

                Debug.Log ("Warning: Trackable not set !!");

            }

    }



    // Update is called once per frame

    void Update () {


  if (mSwapModel && theTrackable != null) {

                SwapModel();

                mSwapModel = false;

            }



    }



    void OnGUI() {

            if (GUI.Button (new Rect(50,50,120,40), "Swap Model")) {

                mSwapModel = true;

            }

        }



        private void SwapModel() 

        {     

            GameObject trackableGameObject = theTrackable.gameObject;



            //disable any pre-existing augmentation

            for (int i = 0; i < trackableGameObject.transform.GetChildCount(); i++) 

            {

                Transform child = trackableGameObject.transform.GetChild(i);

                child.gameObject.active = false;            

            }



            // Create a simple cube object 

            //GameObject model = GameObject.CreatePrimitive(PrimitiveType.Cube);



            if (MyPrefab != null)

            {

                Transform model = GameObject.Instantiate(MyPrefab) as Transform;



                // Re-parent the model as child of the trackable gameObject

                model.parent = theTrackable.transform;



                // Adjust the position and scale 

                // so that it fits nicely on the target

                model.transform.localPosition = new Vector3(0,0.2f,0);

                model.transform.localRotation = Quaternion.identity;//you might need to adjust the rotation

                model.transform.localScale = new Vector3(0.01f, 0.01f, 0.01f);



                // Make sure it is active

                model.active = true;

            }

        }

    }

Answer 1

在删除“预扩充”时，您会移除目标儿童的所有内容，但大象不是 Cow 的子级。获取参考给大象，然后您可以使用SetActive停用它，或者使用Destroy完全删除。

使用Vuforia和Unity交换3D模型
