Question

我环顾四周，并尝试了不同的方法来实现这一目标，但是我没有得到正确的结果。我知道我要的很多，但是我碰到了这堵砖墙，如果可以的话，我将不胜感激。

当玩家挖掘资源时，如果他们从起始位置移动，我希望它停止挖掘。我已经发布了完整的课程，以便您可以看到我在做什么，并希望有人可以指出正确的方向。

您必须使用与启动协程完全相同的参数来停止协程。

来自StopCoroutine：

StopCoroutine采用以下三个参数之一，该参数指定停止哪个协程：


命名活动协程的字符串函数

之前用于创建协程的IEnumerator变量。

协程以停止手动创建的协程。


注意：请勿混合使用三个参数。如果在StartCoroutine中将字符串用作参数，请在StopCoroutine中使用该字符串。同样，在StartCoroutine和StopCoroutine中都使用IEnumerator。最后，将StopCoroutine与用于创建的协同程序一起使用。

因此，您应该预先分配gatherRoutine

gatherRoutine = Gather(timeToGather);
StartCoroutine(gatherRoutine);

及以后

StopCoroutine(gatherRoutine);

或者，您可以使用StopAllCoroutines()来停止协程而不必处理参数（仅在该类中只有一个协程的情况下才应使用）。

public void StopInteract()
{
    Player.MyInstance.MyIsGathering = false;
    Player.MyInstance.animator.SetBool("Mining", Player.MyInstance.MyIsGathering);

    if (gatherRoutine != null)
    {
        StopAllCoroutines();
    }
}

或者您可以使用bool来做

private interuptRoutine = false;

public void Interact()
{
    if (Vector3.Distance(Player.MyInstance.MyTransform.position, transform.position) < interactDistance && Player.MyInstance.MyHasPickaxe == true)
    {
        playerPosition = Player.MyInstance.MyTransform.position;
        // before starting the routine set the interupt flag to false
        interuptRoutine = false;
        StartCoroutine(Gather(timeToGather));
    }
    else
    {
        GameManager.MyInstance.SendMessageToChat("You need to equip a 'Pickaxe' to mine this resource.", Message.MessageType.warning);
    }
}

public void StopInteract()
{
    Player.MyInstance.MyIsGathering = false;
    Player.MyInstance.animator.SetBool("Mining", Player.MyInstance.MyIsGathering);

    if (gatherRoutine != null)
    {
        // only set the interupt flag
        interuptRoutine = true;
    }
}

private IEnumerator Gather(float time)
{
    Player.MyInstance.MyIsGathering = true;
    Player.MyInstance.animator.SetBool("Mining", Player.MyInstance.MyIsGathering);

    // does the same as WaitForSeconds but manually and interupts the routine
    // if interuptRoutine was set to true
    var timePast = 0;
    while(timePast <= time)
    {
        if(interuptRoutine) yield brake;
        timePast += Time.deltaTime;
    }


    Player.MyInstance.MyIsGathering = false;
    Player.MyInstance.animator.SetBool("Mining", Player.MyInstance.MyIsGathering);

    lootTable.ShowLoot();

    if (achievementName != null)
    {
        AchievementManager.MyInstance.EarnAchievement(achievementName);
    }

    Destroy(gameObject);
    Cursor.SetCursor(null, Vector2.zero, cursorMode);
}

播放器移动时需要帮助退出IEnumerator
