達到零后無法使計時器循環

Question

我正在使用一個從設定的數字開始倒數的計時器，當它達到零時，它應該休息一下並重新開始。

private int timer;
public int duration;

private bool timerRunning = true;

void Start()
{
    StartCoroutine("TimeDown");

    timer = duration;
}

void Update()
{

    if (timer <= 0f)
    {
        timer = duration;

        Debug.Log("Timer Reset");

        timerRunning = false;

    }

    if (timerRunning == false)
    {
        StartCoroutine("TimeDown");

        timerRunning = true;
    }


    Debug.Log("Timer: " +timer);
}

IEnumerator TimeDown()
{
    while (true)
    {
        yield return new WaitForSeconds(1);
        timer--;
    }
}

我遇到的問題是使計時器循環。 發送“計時器重置”消息后，它將不再運行計時器。

Answer 1

我建議將邏輯簡化為以下形式：

private int timer;
public int duration;

void Start()
{
    timer = duration;
    StartCoroutine(TimeDown());
}

void Update()
{
    // Nothing is needed each frame so Update() should be removed
}

IEnumerator TimeDown()
{
    while (true)
    {
        if (timer <= 0)
            timer = duration;

        yield return new WaitForSeconds(1);

        timer--;
        Debug.Log("Timer: " + timer);
    }
}

還要確保在檢查器中設置了duration 。
