廢話少說，直接上程式碼。

using UnityEngine;
using System.Collections;

public class shoubingzhendong : MonoBehaviour {

    SteamVR_TrackedObject tracked;
    

	// Use this for initialization
	void Start () {

        tracked = GetComponent<SteamVR_TrackedObject>();
	}
	
	// Update is called once per frame
	void Update () {

        var device = SteamVR_Controller.Input((int)tracked.index);

        //手柄扳機鍵按下
        if (device.GetPressDown(SteamVR_Controller.ButtonMask.Trigger)) { 
        
            //震動
            device.TriggerHapticPulse(500);
        }
	
	}
}
