在StopCoroutine之后重置倒计时时间

using UnityEngine;
using System.Collections;

public class CountdownTimer : MonoBehaviour
{
    public float totalTime = 60f; // 倒计时的总时间

    private Coroutine countdownCoroutine; // 协程的引用

    void Start()
    {
        StartCountdown();
    }

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            StopCountdown();
            ResetCountdown();
            StartCountdown();
        }
    }

    void StartCountdown()
    {
        countdownCoroutine = StartCoroutine(Countdown());
    }

    void StopCountdown()
    {
        if (countdownCoroutine != null)
        {
            StopCoroutine(countdownCoroutine);
        }
    }

    void ResetCountdown()
    {
        totalTime = 60f;
    }

    IEnumerator Countdown()
    {
        while (totalTime > 0)
        {
            yield return null;
            totalTime -= Time.deltaTime;
        }

        Debug.Log("Countdown finished!");
    }
}
