Unity - 动作被调用两次 - OnTriggerEnter、OnClick，一切？

Question

所以我正在创建一个绵羊计数器游戏，昨天，当我上床睡觉时，一切都运行良好。今天，当我打开 Unity 做一些收尾工作时，我所做的一切都被调用了两次...

因此，当我单击开始按钮时，它会调用两次开始游戏，然后当我的羊撞到障碍物时，它会调用两次 OnTriggerEnter。我知道我做错了什么或发生了什么，我宁愿不必重新启动整个项目...

        savedCount = 0;
        deadCount = 0;

    public void AddSavedSheep()
    {
        savedCount++;
        savedText.text = "Saved: " + savedCount;

public class SheepControls : MonoBehaviour
{
    private Rigidbody rb;

    [Header("Movement")]
    [Tooltip("How fast to move GameObject Forward.")]
    public float forwardSpeed = 4.0f;
    [Tooltip("Apply this much force to Rigidbody.")]
    public float jumpForce = 5.0f;
    private float groundY;
    [Space]
    [SerializeField] private bool jumping;
    [SerializeField] private bool isDestroyed;
    [SerializeField] private bool isSaved;

    public ParticleSystem explosionParticles;
    private Counter counter;
    void Start()
    {
        rb = GetComponent<Rigidbody>();
        groundY = (transform.position.y)+0.02f;
        counter = FindObjectOfType<Counter>();
        
    }
    void Update()
    {
        transform.Translate(forwardSpeed * Time.deltaTime * Vector3.forward);
        
        if (Input.GetKeyDown(KeyCode.Space) && !jumping)
        {
            if(transform.position.y < groundY)
            {
                Jump();
            }
        }

        jumping = false;
    }

    private void Jump()
    {
        jumping = true;
        rb.AddForce(Vector3.up * jumpForce);
    }

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("ExplosiveWire"))
        {
            if (isDestroyed) return;
            else
            {
                Debug.Log("Hit Wire");
                isDestroyed = true;
                Destroy(gameObject);             
                Instantiate(explosionParticles, transform.position,
                    explosionParticles.transform.rotation);    
            }
            counter.AddDeadSheep();
        }

        if (other.CompareTag("Goal"))
        {
            if (isSaved) return;
            else
            {
                Debug.Log("Reached Goal");
                isSaved = true;
                Destroy(gameObject);
            }
            counter.AddSavedSheep();
        }
    }

    private void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.CompareTag("Sheep"))
        {
            Physics.IgnoreCollision(this.GetComponent<Collider>(),
                collision.gameObject.GetComponent<Collider>());
        }
    }
}

GameManager 脚本

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

public class GameManager : MonoBehaviour
{
    public bool isGameActive;
    public GameObject titleScreen;
    public GameObject sheepControllerPrefab;

    public void StartGame(int difficulty)
    {
        titleScreen.SetActive(false);
        isGameActive = true;
        InvokeRepeating(nameof(SpawnSheepWave), 2.0f, 2.0f);
    }

    public void Restart()
    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().name);
    }

    public void SpawnSheepWave()
    {
                Instantiate(sheepControllerPrefab, transform.position, 
                    transform.rotation);
    }
}

启动按钮脚本

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

public class DifficultyButton : MonoBehaviour
{
    private Button button;
    private GameManager gameManager;

    [Header("Difficulty Level")]
    [Tooltip("The spawn rate will be divided by this number.")]
    public int difficulty;
    void Start()
    {
        gameManager = GameObject.Find("GameManager").GetComponent<GameManager>();
        button = GetComponent<Button>();
        button.onClick.AddListener(SetDifficulty);
    }

    public void SetDifficulty()
    {
        Debug.Log(gameObject.name + " was clicked.");
        gameManager.StartGame(difficulty);
    }
}

所以，它实际上是将分数加了两次，所以最初我想也许我需要做一个 isDestroyed 或 isSaved 检查并将其添加到脚本中，但似乎没有什么可以阻止它加分两次，或者我认为我点击了开始按钮两次。

Double increment of the score

我觉得我的代码很好，我只是不知道它发生了什么以及为什么它要调用两次。您认为有解决方案吗，或者我可能只需要在新项目中重新创建游戏？

当盒子碰撞器进入触发器时尝试禁用它是否可以解决问题？

羊身上只有一个BoxCollider，围栏上只有一个BoxCollider，球门上只有一个BoxCollider。它们都有刚体并且调用正确，它们一次只发生两次。

感谢你们提供的任何帮助！

我还尝试在 if 语句之前或之后移动增量步骤，看看它是否会做任何不同的事情，但我得到了相同的结果。

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("ExplosiveWire"))
        {
            if (isDestroyed) return;
            else
            {
                Debug.Log("Hit Wire");
                isDestroyed = true;
                Destroy(gameObject);             
                Instantiate(explosionParticles, transform.position,
                    explosionParticles.transform.rotation);
                counter.AddDeadSheep();
            } 
        }

        if (other.CompareTag("Goal"))
        {
            if (isSaved) return;
            else
            {
                Debug.Log("Reached Goal");
                isSaved = true;
                Destroy(gameObject);
                counter.AddSavedSheep();
            }
        }
    }

Answer 1

每次点击您的难度按钮时都会调用开始。其中已经运行。所以你会得到 2。在开始按钮检查器中查看选项
