Question

我制造了＃34; Roll-a-ball＆＃34;来自Youtube上的Unity教程的游戏。但是，我尝试过编程计数器，这很好。问题是当游戏重新启动时，计时器不会，即使我已手动将其设置为00:00，它仍会继续。

void Start()
{
    rb = GetComponent<Rigidbody>();
    count = 0;
    countText.text = "Count: " + count.ToString ();
    winText.text = "";
    restartText.text = "";      
}

void FixedUpdate()
{
    float moveHorizontal = Input.GetAxis("Horizontal");
    float moveVertical = Input.GetAxis("Vertical");

    Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
    rb.AddForce(movement * speed);

    if (Input.GetKeyDown(KeyCode.Space))
    {
        Vector3 jump = new Vector3(0.0f, 250.0f, 0.0f);

        rb.AddForce(jump);
    }

        if (restart)
    {
        if (Input.GetKeyUp(KeyCode.R))
        {
            Application.LoadLevel(Application.loadedLevel);
            timerText.text = minutes.ToString("00") + ":" + seconds.ToString("00"); //HERE
        }
    }
}


void Update()
{
    if (count < 14)
    {
        minutes = (int)(Time.time / 60f);
        seconds = (int)(Time.time % 60f);
        timerText.text = minutes.ToString("00") + ":" + seconds.ToString("00");
    }
}
void OnTriggerEnter(Collider other){
    if (other.gameObject.CompareTag ("Pickup")) {
        other.gameObject.SetActive (false);
        count = count + 1;
        countText.text = "Count: " + count.ToString ();
        if (count >= 14){
            winText.text = "You win!";
            restartText.text = "Press 'R' for Restart";
            restart = true;

        }
    }

}

Answer 1

您只是更新显示输出的文本框，Time.time仍然是游戏首次启动时的时间。

你应该做的是当你创建你的PlayerController时获取当前值Time.time然后使用该值并在你试图弄清楚游戏运行的时间时减去它。

因为您正在重新加载该级别，所以它应该重新初始化脚本，这样您就不需要在级别重新启动时设置文本框的值。

private float _startTime;

void Start()
{
    rb = GetComponent<Rigidbody>();
    count = 0;
    countText.text = "Count: " + count.ToString ();
    winText.text = "";
    restartText.text = "";   
    _startTime = Time.time; //Save the time the game has been running.
}

void FixedUpdate()
{
    float moveHorizontal = Input.GetAxis("Horizontal");
    float moveVertical = Input.GetAxis("Vertical");

    Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
    rb.AddForce(movement * speed);

    if (Input.GetKeyDown(KeyCode.Space))
    {
        Vector3 jump = new Vector3(0.0f, 250.0f, 0.0f);

        rb.AddForce(jump);
    }

    if (restart)
    {
        if (Input.GetKeyUp(KeyCode.R))
        {
            Application.LoadLevel(Application.loadedLevel);
        }
    }
}


void Update()
{
    if (count < 14)
    {
        minutes = (int)((Time.time - _startTime) / 60f); //Subtract the time from the total time.
        seconds = (int)((Time.time - _startTime) % 60f);
        timerText.text = minutes.ToString("00") + ":" + seconds.ToString("00");
    }
}

您应该使用Time.timeSinceLevelLoad代替。

Somethig喜欢这样：

float time = Time.timeSinceLevelLoad;
TimeSpan t = TimeSpan.FromSeconds( secs );
timerText.text = t.ToString(@"mm\:ss");

重启游戏时停止计时计时器
