Question

项目：增强游戏（vuforia）

我有一个飞机可以住球。

飞机上有刚体和网状对撞机。球上有一个球体碰撞器和刚体，并打开了重力。

在我玩游戏时，球从飞机上掉下来并不断掉下。

我希望球保持在飞机上，以便我可以通过触摸输入来控制它。

我遇到了这个问题，我使用I TrackableEventHandler解决了。

查看以下脚本：

using System.Collections;
using UnityEngine;
using Vuforia; 

public class MarkerController: MonoBehaviour, ITrackableEventHandler
{
    private TrackableBehaviour mTrackableBehavior;

    // Start is called before the first frame update
    void Start()
    {
        mTrackableBehavior = GetComponent<TrackableBehaviour>(); 
        if (mTrackableBehavior)
        {
            mTrackableBehavior.RegisterTrackableEventHandler(this); 
        }

    }

    public void OnTrackableStateChanged(TrackableBehaviour.Status previousStatus, TrackableBehaviour.Status newStatus)
    {
        if(newStatus == TrackableBehaviour.Status.DETECTED || newStatus == TrackableBehaviour.Status.TRACKED || newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED)
        {
            OnTrackingFound(); 
        } else
        {
            OnTrackingLost(); 
        }
    }

    private void OnTrackingFound()
    {
        Renderer[] rendererComponents = GetComponentsInChildren<Renderer>();

        Collider[] colliderComponents = GetComponentsInChildren<Collider>(); 


        for (int i = 0; i < this.transform.GetChildCount(); i++)
        {
            Debug.Log("Activating the children");
            this.transform.GetChild(i).gameObject.SetActive(true); 
        }

        foreach(Renderer component in rendererComponents)
        {
            component.enabled = true; 
        }

        foreach(Collider component in colliderComponents)
        {
            component.enabled = true; 
        }

        Debug.Log("Tracking of " + mTrackableBehavior.TrackableName + " found"); 
    }

    private void OnTrackingLost()
    {
        Renderer[] rendererComponents = GetComponentsInChildren<Renderer>();

        Collider[] colliderComponents = GetComponentsInChildren<Collider>();


        for (int i = 0; i < this.transform.GetChildCount(); i++)
        {
            Debug.Log("Deactivating children");
            this.transform.GetChild(i).gameObject.SetActive(false);
        }

        foreach (Renderer component in rendererComponents)
        {
            component.enabled = false;
        }

        foreach (Collider component in colliderComponents)
        {
            component.enabled = false;
        }

        Debug.Log("Tracking of " + mTrackableBehavior.TrackableName + " lost");

    }
}

在本课程中，我仅在找到标记的跟踪时才激活组件！否则，它将被停用，并且当再次找到跟踪时，它将以丢失跟踪之前的状态显示。

我已将此脚本添加到ARCamera组件。在这里工作正常！
