htc vive 控制器3 圓盤 touchpad

htc vive 控制器 圓盤 touchpad
 vive手把圓盤控制

vive圓盤偵測是手指放上去就會偵測，由二為座標組成 Axis(右圖)


vive 回偵測到座標送回,用Controller.GetAxis().x
Controller.GetAxis().y








通常遊戲會用圓盤換武器，或是當按鈕使用通常照座標象限分4等分比較準確


using System.Collections;

using System.Collections.Generic;
using UnityEngine;

public class ControlTest : MonoBehaviour {
  
    private SteamVR_TrackedObject trackedObj;

    public Vector3 controllerTransform;
    private float touchpad_Recordy;
    private SteamVR_Controller.Device Controller
    {
        get { return SteamVR_Controller.Input((int)trackedObj.index); }
    }

    void Awake()
    {
        trackedObj = GetComponent<SteamVR_TrackedObject>();
    }
    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        // 1
     
        if (Controller.GetAxis().x > 0 && Controller.GetAxis().y > 0 && Controller.GetPressDown(SteamVR_Controller.ButtonMask.Touchpad))
        {
            Debug.Log("按圓盤右上");
        }
        if (Controller.GetAxis().x > 0 && Controller.GetAxis().y > 0 && Controller.GetPressUp(SteamVR_Controller.ButtonMask.Touchpad))
        {
            Debug.Log("放開圓盤右上");
        }
        if (Controller.GetAxis().x > 0 && Controller.GetAxis().y > 0 && Controller.GetTouch(SteamVR_Controller.ButtonMask.Touchpad))
        {
            Debug.Log("手位置圓盤右上");//
        }

        if (Controller.GetAxis().x < 0 && Controller.GetAxis().y > 0 && Controller.GetPressDown(SteamVR_Controller.ButtonMask.Touchpad))
        {
            Debug.Log("圓盤左上");
        }
        if (Controller.GetAxis().x > 0 && Controller.GetAxis().y < 0 && Controller.GetPressDown(SteamVR_Controller.ButtonMask.Touchpad))
        {
            Debug.Log("圓盤右下");
        }
        if (Controller.GetAxis().x < 0 && Controller.GetAxis().y < 0 && Controller.GetPressDown(SteamVR_Controller.ButtonMask.Touchpad))
        {
            Debug.Log("圓盤左下");
        }

       
    }
}

Controller.GetPressDown( 裡放的是一個參數對應控制按鈕) 例如:圓盤(tochpad)或是板機(trigger)

steamvr 定義好了buttonMask 來對應參數


//Controller.GetPressDown("控制器對應的Mask參數")

//Controller.GetPressDown(SteamVR_Controller.ButtonMask.Touchpad)) //








public class SteamVR_Controller
{
    public class ButtonMask
    {
        public const ulong System            = (1ul << (int)EVRButtonId.k_EButton_System); // reserved
        public const ulong ApplicationMenu    = (1ul << (int)EVRButtonId.k_EButton_ApplicationMenu);
        public const ulong Grip                = (1ul << (int)EVRButtonId.k_EButton_Grip);
        public const ulong Axis0            = (1ul << (int)EVRButtonId.k_EButton_Axis0);
        public const ulong Axis1            = (1ul << (int)EVRButtonId.k_EButton_Axis1);
        public const ulong Axis2            = (1ul << (int)EVRButtonId.k_EButton_Axis2);
        public const ulong Axis3            = (1ul << (int)EVRButtonId.k_EButton_Axis3);
        public const ulong Axis4            = (1ul << (int)EVRButtonId.k_EButton_Axis4);
        public const ulong Touchpad            = (1ul << (int)EVRButtonId.k_EButton_SteamVR_Touchpad);
        public const ulong Trigger            = (1ul << (int)EVRButtonId.k_EButton_SteamVR_Trigger);
    }

steamvr 定義好的Mask


參照上圖 名子

Axis0   是圓盤觸碰

Axis1~4 還沒用處
