[游戏开发]Unity HTC ViveInputUtility总结

HandRole包括

public enum HandRole
    {
        Invalid = -1,
        RightHand,
        LeftHand,
        ExternalCamera,
        Controller3 = ExternalCamera,
        Controller4,
        Controller5,
        Controller6,
        Controller7,
        Controller8,
        Controller9,
        Controller10,
        Controller11,
        Controller12,
        Controller13,
        Controller14,
        Controller15,
    }

按钮包括

• 开关、系统菜单按钮：只有这个按钮不可以编程（默认），用来打开手柄，其实没用关的功能。在游戏中按下该按钮是调出系统默认的菜单，用来关闭，切换游戏用的。
• menu按钮：默认用来打开游戏菜单。
• grip按钮：用的最少的按钮，每个手柄上虽然有两个，但是是相同的。
• trigger按钮：扳机按钮，用的最多，可以有力度。
• pad：触摸屏+鼠标的功能，可触摸，可点击。

1、静态类Vive Input

public class GetPressDown_ViveInput : MonoBehaviour
{
    private void Update()
    {
        if (ViveInput.GetPressDown(HandRole.RightHand,ControllerButton.Trigger))
        {
            //TODO
        }
    }
}

2、?监听按钮事件：?
?

public class GetPressDown_ViveInputHandler : MonoBehaviour
{
    private void Awake()
    {
        ViveInput.AddPressDown(HandRole.LeftHand, ControllerButton.Trigger, Ontrigger);
    }
    private void OnDestroy()
    {
        ViveInput.RemovePressDown(HandRole.LeftHand,ControllerButton.Trigger, Ontrigger);
    }

    private void Ontrigger()
    {
        throw new NotImplementedException();
    }
}

3、获得追踪pose：?
? ? ? ?? ?? ?? ?静态类VivePose提供了获得设备pose的API；?
?

public class GetPoseExample : MonoBehaviour
{
    //使go跟随右手
    public GameObject deviceOrigin;
    public Transform goTrans;
    private void Start()
    {
        deviceOrigin = GameObject.Find("VROrigin");
    }
    private void Update()
    {
        VivePose.SetPose(goTrans, HandRole.RightHand, deviceOrigin.transform);
    }
}

事件响应

vive支持以下事件?

• IColliderEventHoverEnterHandler
• IColliderEventHoverExitHandler
• IColliderEventPressDownHandler
• IColliderEventPressUpHandler
• IColliderEventPressEnterHandler
• IColliderEventPressExitHandler
• IColliderEventClickHandler
• IColliderEventDragStartHandler
• IColliderEventDragUpdateHandler
• IColliderEventDragEndHandler
• IColliderEventDropHandler
• IColliderEventAxisChangedHandler

使用方法，新建脚本如下，并把脚本添加到游戏对象，即可。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using HTC.UnityPlugin.ColliderEvent;
 
public class viveLearn : MonoBehaviour,IColliderEventHoverEnterHandler 
{
 
    public void OnColliderEventHoverEnter(ColliderHoverEventData eventData){

        Debug.Log ("hover");

    }
}
