如何使倒數計時器復位或 go 備份幾秒鍾？

Question

我試圖讓這個時間 go 及時上升 5 秒，或者在我輸入觸發器時重置。

using System.Collections;
using UnityEngine.UI;
using UnityEngine;
using UnityEngine.SceneManagement;

public class Timer2 : MonoBehaviour
{

    public float timeLeft = 3.0f;
    public Text startText; // used for showing countdown from 3, 2, 1 


    void Update()
    {
        timeLeft -= Time.deltaTime;
        startText.text = (timeLeft).ToString("0");
        if (timeLeft < 0)
        {
            if (timeLeft < 0)
            {
                SceneManager.LoadScene("GameOver");
            }
        }

Answer 1

您是否嘗試過簡單地添加到timeLeft變量？

using System.Collections;
using UnityEngine.UI;
using UnityEngine;
using UnityEngine.SceneManagement;

public class Timer2 : MonoBehaviour
{

public float timeLeft = 3.0f;
public Text startText; // used for showing countdown from 3, 2, 1 


void Update()
{
    timeLeft -= Time.deltaTime;
    startText.text = (timeLeft).ToString("0");
    if (timeLeft < 0)
    {
        if (timeLeft < 0)
        {
            SceneManager.LoadScene("GameOver");
        }
    }
}

void OnTriggerEnter2D(Collider2D col)
{
    //check to see if the collision is correct
    timeLeft += 5; //parameterize this number if needed
}
}

如果您想重置timeLeft ，只需替換timeLeft += 5; 使用timeLeft = 3.0f （如果要這樣做，您可能希望將初始值移動到變量中）
