VRTK3.3.0-003发出一条简单射线和监听

Posted 2021-12-02 myunity

1丶在Right下继续添加脚本VRTK_Pointer和VRTK_StraightPointerRenderer

运行后默认是按住圆盘键出现射线，松开消失，大家可以自定义

2丶射线的监听事件

（1）在场景中创建一个Cube用来触发射线检测用，位于相机前方([VRTK_SDKManager]的Z轴方向)

（2）在Right上新建脚本SimplePointerEvents，通过得到VRTK_DestinationMarker组件注册方法，就可以监听射线的触发了

　　注意：VRTK_Pointer组件是继承于VRTK_DestinationMarker组件

using UnityEngine;
using VRTK;//   引用VRTK命名空间

    public class SimplePointerEvents : MonoBehaviour
    {
    private VRTK_DestinationMarker destinationMarker;
    private void Awake()
    {
        destinationMarker = GetComponent<VRTK_DestinationMarker>();
        destinationMarker.DestinationMarkerEnter += DestinationMarker_DestinationMarkerEnter;
        destinationMarker.DestinationMarkerExit += DestinationMarker_DestinationMarkerExit;
        destinationMarker.DestinationMarkerHover += DestinationMarker_DestinationMarkerHover;
        destinationMarker.DestinationMarkerSet += DestinationMarker_DestinationMarkerSet;
    }

    private void DestinationMarker_DestinationMarkerSet(object sender, DestinationMarkerEventArgs e)
    {
        Debug.Log("与物体交互");
    }
    private void DestinationMarker_DestinationMarkerHover(object sender, DestinationMarkerEventArgs e)
    {
        Debug.Log("射线悬停物体");
    }
    private void DestinationMarker_DestinationMarkerExit(object sender, DestinationMarkerEventArgs e)
    {
        Debug.Log("射线退出物体");
    }

    private void DestinationMarker_DestinationMarkerEnter(object sender, DestinationMarkerEventArgs e)
    {
        Debug.Log("射线进入物体");
    }
}
