阻止不了Coroutine

Question

伙计们，当我先给它贴上披萨标签的食物时，我怎么能阻止它呢？

请帮帮我，我找不到路。我该怎么办？顺便说一句，我是新来的，很抱歉发帖不好:/

我在做比萨饼店的游戏。所以顾客会坐着等披萨，如果我们给披萨贴标签，服务员就应该开始，然后开始吃比萨饼，但我的服务生比萨饼并没有停止。

IEnumerator EAT, PAY, WAIT;

private void Start()
{
    EAT = EatPizza();
    WAIT = WaitForPizza();
    PAY = WaitForTheCase();
}

private void OnTriggerEnter(Collider other)
{
    if (other.gameObject.CompareTag("Pizza"))
    {
        canEat = true;
    }

    if (other.gameObject.CompareTag("Out"))
    {
        Destroy(this.gameObject);
    }
}

void Update()
{
    if (isEating)
    {
        if (Vector3.Distance(transform.position, agent.destination) <= 1f)
        {
            anim.SetTrigger("sit");
            isEating = false;
        }
    }

    if (!isEating && !isPaying && !isOut && !canEat)
    {
        StartCoroutine(WaitForPizza());
    }

    if (!isEating && !isPaying && !isOut && canEat)
    {
        StopCoroutine(WAIT);
        StartCoroutine(EatPizza());
    }

    if (isPaying)
    {
        isEating = false;
        anim.SetTrigger("walk");
        
        agent.destination = checkoutTarget.position;
        if (Vector3.Distance(transform.position, agent.destination) <= 1f)
        {
            anim.SetTrigger("wait");
            if (ifCashier)
            {
                //throw money 
                isPaying = false;

                isOut = true;
            }

            if (!ifCashier)
            {
                StartCoroutine(WaitForTheCase());
            }
        }
    }

    if (isOut)
    {
        anim.SetTrigger("walk");
        isEating = false;
        isPaying = false;
        
        agent.destination = outTarget.position;
    }

    if (canEat)
    {
        StopCoroutine(WAIT);
    }
}

IEnumerator WaitForTheCase()
{
    anim.SetTrigger("wait");
    yield return new WaitForSeconds(randomFloatWait);
    angry.SetActive(true);
    
    isEating = false;
    isPaying = false;
    isOut = true;
}

IEnumerator EatPizza()
{
    angry.SetActive(false);
    StopCoroutine(WaitForPizza());
    happy.SetActive(true);
    yield return new WaitForSeconds(randomFloatWait);
    
    happy.SetActive(false);
    isEating = false;
    isPaying = true;
    isOut = false;
}

IEnumerator WaitForPizza()
{
    while (!canEat)
    {
        yield return new WaitForSeconds(randomFloatWait);
        angry.SetActive(true);
    
        isEating = false;
        isPaying = false;
        isOut = true;
    }
}

首先，将WAIT定义为Coroutine，然后当您想要开始等待时使用WAIT = StartCoroutine(WaitForPizza());，当您想要完成它时使用StopCoroutine(WAIT);。
