Question

我目前已将此代码附加到玩家身上，以启动计时器，该计时器在输入触发器时结束，但是我想使其在输入触发器而不是在开始游戏时启动。

public class Timer : MonoBehaviour
{
    public Text timerText;
    private float startTime;
    private bool finished = false;
    private bool started = false;


    void Update()
    {
        if (finished)
            return;

        if (started)
        { 
            float t = Time.time - startTime;

            string minutes = ((int)t / 60).ToString();
            string seconds = (t % 60).ToString("f2");

            timerText.text = minutes + ":" + seconds;
        }
    }

    public void Finish()
    {
        finished = true;
        timerText.color = Color.yellow;
    }

    void Start()
    {
        started = true;
    }
}

您可以执行与bool finished相同的操作，但是它将类似于bool started，当玩家进入启动触发器时，它将返回true。将其包装在Update()语句中随时间变化的代码中。

确保Timer中的布尔对象是公开的：

public Text timerText;
public bool finished = false;
public bool started = false;

private float t = 0f;

void Update()
{
   if (finished)
      return;

   if (started) 
      t += Time.deltaTime;

   string minutes = ((int)t / 60).ToString();
   string seconds = (t % 60).ToString("f2");

   timerText.text = minutes + ":" + seconds;
}

void Started() 
{
    started = true;
}

然后在触发脚本中，引用连接到Player的Timer。

public class StartTrigger : MonoBehaviour 
{

    private GameObject player;
    private Timer timer;

    void Start() 
    {
        player = GameObject.FindWithTag("Ellen");
        if (player)
            timer = player.GetComponent<Timer>();
    }

    void OnTriggerEnter(Collider other) 
    {
        if (other.tag == "Ellen") 
        {
            timer.Started();
        }
    }
}

玩家进入物体后触发一个计时器，当物体进入另一个物体时停止
