Unity如何深入使用Vuforia

之前写过一篇unity使用vuforia做开发的一个案例，今天只不过在上一次的基础上，再深挖一下

本文要重点突出实现如下功能：

普通游戏 —–> AR

---

具体如下：

---

点击按钮后，调用的方法

    public  void kaiShiShiBie01(){  
        arcam.SetActive (true);   //开启AR相机  
        maincam.SetActive (false);   //关掉主相机
        btn.gameObject.SetActive (false);   //按钮也关掉
    }

DefaultTrackableEventHandler.cs

        private void OnTrackingFound()  //发现目标就调用，注意发现后只会执行一次
        {
            Renderer[] rendererComponents = GetComponentsInChildren<Renderer>(true);
            Collider[] colliderComponents = GetComponentsInChildren<Collider>(true);

            // Enable rendering:
            foreach (Renderer component in rendererComponents)
            {
                component.enabled = true;
            }

            // Enable colliders:
            foreach (Collider component in colliderComponents)
            {
                component.enabled = true;
            }
            //
            Debug.Log("Trackable " + mTrackableBehaviour.TrackableName + " found");  //注意这里，参考下面截图

            //haitao.instance.found1 ();
        }


        private void OnTrackingLost() //目标跟踪丢失，就调用一次
        {
            Renderer[] rendererComponents = GetComponentsInChildren<Renderer>(true);
            Collider[] colliderComponents = GetComponentsInChildren<Collider>(true);

            // Disable rendering:
            foreach (Renderer component in rendererComponents)
            {
                component.enabled = false;
            }

            // Disable colliders:
            foreach (Collider component in colliderComponents)
            {
                component.enabled = false;
            }

            Debug.Log("Trackable " + mTrackableBehaviour.TrackableName + " lost");
        }
