將捏合縮放轉換為新的 InputSystem

Question

我正在嘗試使用 EnhancedTouch.Touch 將捏合縮放從舊輸入轉換為新輸入系統。 不幸的是，我對如何從這里前進一無所知？ 我收到錯誤消息，因為Operator '==' cannot be applied to operands of type 'TouchPhase' and 'TouchPhase' 。 我該如何解決？

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.InputSystem.EnhancedTouch;
using Touch = UnityEngine.InputSystem.EnhancedTouch.Touch;

public class ZoomTouch : MonoBehaviour {
public Camera camera;
float touchDist = 0;
float lastDist = 0;

public void Update () {

if (Input.touchCount == 2) {
            Touch touch1 = Touch.activeFingers[0].currentTouch;
            Touch touch2 = Touch.activeFingers[0].currentTouch;

            if (touch1.phase == TouchPhase.Began && touch2.phase == TouchPhase.Began) {
                lastDist = Vector2.Distance (touch1.position, touch2.position);
            }

            if (touch1.phase == TouchPhase.Moved && touch2.phase == TouchPhase.Moved) {
                float newDist = Vector2.Distance (touch1.position, touch2.position);
                touchDist = lastDist - newDist;
                lastDist = newDist;

                camera.fieldOfView += touchDist * 0.1f;

            }
        }

    }
}

我希望這段代碼有效。 但是，我沒有觸摸設備來測試它。 這個簡單的代碼可以工作，獲取現在和過去之間的距離，並放大它們的增量。

public float lastDistance;
public float distance;
void Update()
{
    if (Input.touchCount < 2) return;

    var touch1 = Input.GetTouch(0);
    var touch2 = Input.GetTouch(1);
    
    distance = Vector2.Distance(touch1.position, touch1.position);

    if (Mathf.Abs(lastDistance-distance) >= 10) lastDistance = distance; // for avoiding sharp zooms on first touch
    
    Camera.main.fieldOfView += distance-lastDistance * 0.1f;

    lastDistance = distance;
}
