我有一个有效的滑动检测器脚本，但我不知道如何将它连接到我的角色控制器

Question

我的游戏是一个无尽的跑步者，角色只需要沿着 y 轴移动。 我想要发生的是玩家根据滑动向上或向下移动，我认为我可以通过说明如果玩家触发 onSwipeUp 或向下然后他们会朝那个方向移动来做到这一点，但我不能让它工作。

这是我尝试在其中实施滑动控件之前的播放器控制器脚本：

public class Player : MonoBehaviour
{

private Vector2 targetPos;

public float yIncrement;
public float maxHeight;
public float minHeight; 

private void Update()
    {

    transform.position = Vector2.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);

    if (Input.GetKeyDown(KeyCode.W) && transform.position.y < maxHeight)
    {
        Instantiate(effect, transform.position, Quaternion.identity);
        targetPos = new Vector2(transform.position.x, transform.position.y + yIncrement);
    }
    else if (Input.GetKeyDown(KeyCode.S) && transform.position.y > minHeight)
    {
        Instantiate(effect, transform.position, Quaternion.identity);
        targetPos = new Vector2(transform.position.x, transform.position.y - yIncrement);
    }
}

这是刷卡检测脚本：

 using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SwipeTest : MonoBehaviour
{
    private Vector2 fingerDown;
    private Vector2 fingerUp;
    public bool detectSwipeOnlyAfterRelease = false;
public float SWIPE_THRESHOLD = 20f;

// Update is called once per frame
void Update()
{

    foreach (Touch touch in Input.touches)
    {
        if (touch.phase == TouchPhase.Began)
        {
            fingerUp = touch.position;
            fingerDown = touch.position;
        }

        //Detects Swipe while finger is still moving
        if (touch.phase == TouchPhase.Moved)
        {
            if (!detectSwipeOnlyAfterRelease)
            {
                fingerDown = touch.position;
                checkSwipe();
            }
        }

        //Detects swipe after finger is released
        if (touch.phase == TouchPhase.Ended)
        {
            fingerDown = touch.position;
            checkSwipe();
        }
    }
}

void checkSwipe()
{
    //Check if Vertical swipe
    if (verticalMove() > SWIPE_THRESHOLD && verticalMove() > horizontalValMove())
    {
        //Debug.Log("Vertical");
        if (fingerDown.y - fingerUp.y > 0)//up swipe
        {
            OnSwipeUp();
        }
        else if (fingerDown.y - fingerUp.y < 0)//Down swipe
        {
            OnSwipeDown();
        }
        fingerUp = fingerDown;
    }

    //Check if Horizontal swipe
    else if (horizontalValMove() > SWIPE_THRESHOLD && horizontalValMove() > verticalMove())
    {
        //Debug.Log("Horizontal");
        if (fingerDown.x - fingerUp.x > 0)//Right swipe
        {
            OnSwipeRight();
        }
        else if (fingerDown.x - fingerUp.x < 0)//Left swipe
        {
            OnSwipeLeft();
        }
        fingerUp = fingerDown;
    }

    //No Movement at-all
    else
    {
        //Debug.Log("No Swipe!");
    }
}

float verticalMove()
{
    return Mathf.Abs(fingerDown.y - fingerUp.y);
}

float horizontalValMove()
{
    return Mathf.Abs(fingerDown.x - fingerUp.x);
}

Answer 1

您可以为每个滑动方向设置一个公共布尔值。 在更新的第一行将这些布尔值设置为 false，在 onswipe 函数中将相应的布尔值设置为 true。 然后从播放器脚本中引用 swipetest 脚本并检查所需的 swipe 布尔值是否设置为 true。

代码看起来像这样：

球员：

public class Player : MonoBehaviour
{

private Vector2 targetPos;

public float yIncrement;
public float maxHeight;
public float minHeight; 

public SwipeTest swipetest;

private void OnEnable()
{
  swipetest = (SwipeTest)FindObjectOfType(typeof(SwipeTest));
}

private void Update()
    {

    transform.position = Vector2.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);

    if (swipetest.swipeUp && transform.position.y < maxHeight)
    {
        Instantiate(effect, transform.position, Quaternion.identity);
        targetPos = new Vector2(transform.position.x, transform.position.y + yIncrement);
    }
    else if (swipetest.swipeDown && transform.position.y > minHeight)
    {
        Instantiate(effect, transform.position, Quaternion.identity);
        targetPos = new Vector2(transform.position.x, transform.position.y - yIncrement);
    }
}
