（Unity 2D手机）我需要区分按钮触摸和屏幕触摸

Question

我正在制作一款手机 2d 游戏。我在屏幕右下角有一个发射激光的按钮。我确实有一个喷气背包脚本，当触摸屏幕时，它会增加力量让玩家上升。但是当我触摸射击按钮时，它会发射激光并让玩家上升。我需要区分它们。

Jetpack 脚本：

public class Jetpack : MonoBehaviour
{

    public static Jetpack instance;

    public float speed, jumpForce;

    Rigidbody2D rb;

    ParticleSystem ps;

    public float health = 3f;

    public TMPro.TextMeshProUGUI HealthText;

    public TMPro.TextMeshProUGUI GoldText;

    public float Gold = 0f;

    public Transform laserSpawnPosition;

    public GameObject laser;

    public AudioClip[] audios;

    public string prefHighScore = "The High Score: ";

    public float score;

    public float highScore;

    public float scoreMultiplier = 1f;

    public TMPro.TextMeshProUGUI ScoreText;

    public TMPro.TextMeshProUGUI HighScoreText;

    public GameObject panelGameOver;

    //public bool isShooting = false;

    private void Awake()
    {

        rb = GetComponent<Rigidbody2D>();

        instance = GetComponent<Jetpack>();

        ps = GetComponentInChildren<ParticleSystem>();

        HealthText.text = health + "";

        GoldText.text = Gold + "";

        panelGameOver.SetActive(false);
    }

    // Start is called before the first frame update
    void Start()
    {

        score = 0;

        health = 3f;

        Gold = 0;

        highScore = PlayerPrefs.GetInt(prefHighScore, 0);

        Time.timeScale = 1;

        HighScoreText.text = "Your High Score: " + highScore;
    }

    // Update is called once per frame
    void Update()
    {
        
        ScoreText.text = (int)score + "";

        score += Time.deltaTime * 10 * scoreMultiplier;

        GoldText.text = (int)Gold + "";

        HealthText.text = (int)health + "";

        if (Input.GetKeyDown(KeyCode.Space))
        {
            ps.Play();
        }
       
        
        // new                      // new
        if (Input.GetKey(KeyCode.Space) || Input.GetMouseButton(0) || Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
        {
            rb.AddForce(Vector2.up * jumpForce);
        }

        if (Input.GetKeyUp(KeyCode.Space))
        {
            ps.Stop();
        }

        if (health <= 0)
        {
            Debug.Log("You are dead...");

            //HealthText.text = "0";

            panelGameOver.SetActive(true);

            Time.timeScale = 0;
        }

        //if (Input.GetButtonDown("Fire1"))
        //{
            //FireLaser();

            //Debug.Log("Shooting Laser");
        //}
    }

    public void AddHealth()
    {
        health += 1;
    }

    public void AddGold()
    {
        Gold += 1;
    }

    void FireLaser()
    {

        Instantiate(laser, laserSpawnPosition.position, Quaternion.identity);

        PlayLaserSound();

    }

    public void MobileFireLaser()
    {
        FireLaser();
    }

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.gameObject.tag == "Gold")
        {
            AddGold();

            PlayGoldSound();

            Debug.Log("Gold: " + Gold);

            Destroy(collision.gameObject);
        }
    }

    public void PlayHitSound()
    {
        AudioSource.PlayClipAtPoint(audios[0], new Vector3(transform.position.x, transform.position.y, transform.position.z));
    }

    public void PlayHealthSound()
    {
        AudioSource.PlayClipAtPoint(audios[1], new Vector3(transform.position.x, transform.position.y, transform.position.z));
    }

    public void PlayGoldSound()
    {
        AudioSource.PlayClipAtPoint(audios[2], new Vector3(transform.position.x, transform.position.y, transform.position.z));
    }

    public void PlayLaserSound()
    {
        AudioSource.PlayClipAtPoint(audios[3], new Vector3(transform.position.x, transform.position.y, transform.position.z));
    }

    private void OnDisable()
    {
        if (score > highScore)
        {
            PlayerPrefs.SetInt(prefHighScore, (int)score);
        }
    }
}

移动 UI 控制器脚本：

public class MobileUICtrl : MonoBehaviour
{


    public GameObject player;

    Jetpack playerCtrl;

    // Start is called before the first frame update
    void Start()
    {
        playerCtrl = player.GetComponent<Jetpack>();
    }

    public void MobileFireLaser()
    {
        playerCtrl.MobileFireLaser();
    }
}

请帮忙！先感谢您。

Answer 1

从根本上讲，您的问题是您有两项重叠的输入检查。您在右下角有一张检查，并进行覆盖整个屏幕的检查。但是由于整个屏幕都包含右下角，因此它们都同时发生。

有多种方法可以团结一致，我不会全部介绍它们。但是，我将概述我认为是最好的方法。

分层UI按钮

我不确定您是如何进行当前输入检查（代码似乎只处理键盘输入？），但这是使用帆布上使用按钮的理想用例。您只需在屏幕上放置两个按钮即可。一个占用整个屏幕，另一个在角落的顶部。您可以通过进入gameObject＆gt;可以轻松地放置按钮;创建＆gt; ui＆gt;按钮。 并根据需要进行配置。

然后，您禁用图像组件以防止它们覆盖整个屏幕，瞧！两个不矛盾的按钮。

在您的脚本中，我将检查我的触摸或指针是否位于 ui 上

if (Input.GetKey(KeyCode.Space) || Input.GetMouseButton(0) || Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
    {
        //Here I would check if my pointer or touch is over UI if not I will add force
        If(!IsOverUI()){
            rb.AddForce(Vector2.up * jumpForce);
        }
    }

，并且 IsOverUI() 如下所示

public bool IsOverUI()
{
    PointerEventData eventDataCurrentPosition = new PointerEventData(EventSystem.current);
    eventDataCurrentPosition.position = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
    List<RaycastResult> results = new List<RaycastResult>();
    EventSystem.current.RaycastAll(eventDataCurrentPosition, results);
    return results.Count > 0;
}
