Question

我已经研究了如何制作倒数计时器。我想制作一个计时器来计算我在检查器中指定的分钟和秒数。当我点击一个对象时，计时器会减少几分钟和/或几秒钟。我稍后会做出决定。下面是我的代码。谢谢！

using UnityEngine;
using System.Collections;

public class controllerScript : MonoBehaviour {

    public GUIText timerText;
    public float minutes;


    void Start(){
        timerText.text = "";
    }

    void Update(){
        if (Input.GetMouseButtonDown(0)){
            Debug.Log("pressed left click, casting ray");
            CastRay();
        }

        minutes -= Time.deltaTime;
        timerText.text = minutes.ToString("f0") + "";
    }

    void CastRay(){
        Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
        RaycastHit2D hit = Physics2D.Raycast (ray.origin, ray.direction, Mathf.Infinity);

        //start statements for what happens when Objects are clicked
        if (hit.collider.gameObject.name == "target01"){
            Debug.Log("you've click obj 1, good work.");

        }
        if (hit.collider.gameObject.name == "target02"){
            Debug.Log("well that's obj 2, even better!");
        }
    }

}

不知道，你的问题究竟是什么，但你应该意识到，Time.deltaTime是以秒为单位的时间，而不是几分钟。

所以你应该改变这一行

minutes -= Time.deltaTime;

到

minutes -= Time.deltaTime / 60.0;

统一c＃倒计时器用于动态时间
