2.VRtk 插件

按键输入：

注册事件到对应手柄的VRTK_ControlEvent 上

using UnityEngine;
using System.Collections;
using VRTK;

public class Test: Monobehavior

{

VRTK_ControlEvent event_vrtk ;

void Start() {

event_vrtk = GetComponent< VRTK_ControlEvent>();

// 事件加入方法指针，不是调用，不用“（）”

event_vrtk .triggerPressed += OnTriggerPressesdMethd;

}

// Trigger 键按下 -----加入的方法种类，和定义的委托时种类一致，都是含有俩个参数的方法

public void OnTriggerPressesdMethd(Objectsender obj, MESA a ){

Debug.Log("TriggerPresses");

}

物体交互：

using UnityEngine;
using System.Collections;
using VRTK;
using PlayMaker;

public class Whirlygig : VRTK_InteractableObject
{

public PlayMakerFSM fsm;

// 射线进入
public override void StartUsing(GameObject usingObject)
{

base.StartUsing(usingObject);

// 发送事件----事件可以执行一大堆这个事件下的方法；

fsm.SendEvent("Clickkk");

Debug.Log("-------------------------------------------------");
}

//射线出来时调用
public override void StopUsing(GameObject usingObject)
{
base.StopUsing(usingObject);

}

// 开始方法

protected override void Start()
{
base.Start();

}

protected override void Update()
{

}
}
