我在Unity中使用了C＃秒表类，但它只返回00:00:00(I used the C# Stopwatch Class in Unity, but it returns only 00:00:00)

我想测量并返回用户按Tab键和空格键之间经过的时间。 不幸的是，我的代码只返回00:00:00。 到目前为止这是我的代码。

using System.Collections; using System.Collections.Generic; using UnityEngine; using System.Threading; using System; using System.Diagnostics; using Debug=UnityEngine.Debug; public class timer : MonoBehaviour { public Stopwatch zeit; void Update () { zeit = new Stopwatch(); if (Input.GetKeyDown ("tab")) { zeit.Start(); } if (Input.GetKeyDown ("space")){ TimeSpan ts = zeit.Elapsed; zeit.Stop (); print(ts); zeit.Reset (); } } }


I want to measure and return the time that passes between the time a user presses the Tab & the Space Button. Unfortunately my Code only returns 00:00:00. This is my code so far.

using System.Collections; using System.Collections.Generic; using UnityEngine; using System.Threading; using System; using System.Diagnostics; using Debug=UnityEngine.Debug; public class timer : MonoBehaviour { public Stopwatch zeit; void Update () { zeit = new Stopwatch(); if (Input.GetKeyDown ("tab")) { zeit.Start(); } if (Input.GetKeyDown ("space")){ TimeSpan ts = zeit.Elapsed; zeit.Stop (); print(ts); zeit.Reset (); } } }


最满意答案

您在调用更新时重新创建秒表。 您可以在“构造函数”中正手初始化秒表。

public Stopwatch zeit = new StopWatch(); void Update () { if (Input.GetKeyDown ("tab")) { zeit.Start(); } if (Input.GetKeyDown ("space")){ TimeSpan ts = zeit.Elapsed; zeit.Stop (); print(ts); zeit.Reset (); } }

You are re-creating the stopwatch when calling update. You can initialize the stopwatch on forehand in the "constructor".

public Stopwatch zeit = new StopWatch(); void Update () { if (Input.GetKeyDown ("tab")) { zeit.Start(); } if (Input.GetKeyDown ("space")){ TimeSpan ts = zeit.Elapsed; zeit.Stop (); print(ts); zeit.Reset (); } }
