如何在Unity中制作暂停菜单以在Unity 4.6中停止计时器

Question

How can i make a pause menu in unity which stops a timer in unity 4.6 ? Here is the script :

using UnityEngine;
using System.Collections;

public class pauseMenu : MonoBehaviour 
{
    public GUISkin myskin;

private Rect windowRect;
private bool paused = false , waited = true;

private void Start()
{
    windowRect = new Rect(Screen.width / 2 - 100, Screen.height / 2 - 100, 200, 200);
}

private void waiting()
{
    waited = true;
}

private void Update()
{
    if (waited)
        if (Input.GetKey(KeyCode.Escape) || Input.GetKey(KeyCode.P))
        {
            if (paused)
                paused = false;
            else
                paused = true;

            waited = false;
            Invoke("waiting",0.3f);
        }
}

private void OnGUI()
{
    if (paused)
        windowRect = GUI.Window(0, windowRect, windowFunc, "Pause Menu");
}

private void windowFunc(int id)
{
    if (GUILayout.Button("Resume"))
    {
        paused = false;
    }
    if (GUILayout.Button ("Restart")) 
    {
        Application.LoadLevel("LEVEL 1");
    }
    if (GUILayout.Button("Quit"))
    {
        Application.LoadLevel("Main Menu");
    }
}
}

Edit : After checking your actual project

Problem

You are using two different classes for creating timer, one is "pauseMenu" which you have mentioned in your question and other one is "Timer" which is this one

#pragma strict

var timer : float = 10.0;

function Update()
{
    timer -= Time.deltaTime;

    if(timer <= 0)
    {
        timer = 0;
        //DO SOMETHING EPIC!
    }
}


function OnGUI()
{
    GUI.Box(new Rect(1, 2, 70, 30), "Time: " + timer.ToString("0"));
}

Now please note first class is written in C# and the other class is in javascript.

There are two solution to achieve you goal

1.

Using both script together is very tricky, you need to keep your first script in plugin folder, because of unity's execution order and access "time" variable from javascript. or

2.

You can delete your javascript "timer" and update your C# class "pauseMenu" with following code.

*************************** New Code ***********************

using UnityEngine;
using System.Collections;

public class pauseMenu : MonoBehaviour 
{
    public GUISkin myskin;

    private Rect windowRect;
    private bool paused = false , waited = true;
    private float time = 60f;

    private void Start()
    {
        windowRect = new Rect(Screen.width / 2 - 100, Screen.height / 2 - 100, 200, 200);
    }

    private void waiting()
    {
        waited = true;
    }

    private void Update()
    {
        if (waited)
            if (Input.GetKey(KeyCode.Escape) || Input.GetKey(KeyCode.P))
        {
            if (paused)
                paused = false;
            else
                paused = true;

            waited = false;
            Invoke("waiting",0.3f);
        }
        if(!paused)
            if(time>0)
                time -= Time.deltaTime;
    }

    private void OnGUI()
    {
        if (paused)
            windowRect = GUI.Window(0, windowRect, windowFunc, "Pause Menu");
        GUI.Box(new Rect(1, 2, 70, 30), "Time: " + time.ToString("0"));
    }

    private void windowFunc(int id)
    {
        if (GUILayout.Button("Resume"))
        {
            paused = false;
        }
        if (GUILayout.Button ("Restart")) 
        {
            Application.LoadLevel("LEVEL 1");
        }
        if (GUILayout.Button("Quit"))
        {
            Application.LoadLevel("Main Menu");
        }
    }
}

Like this

using UnityEngine;
using System.Collections;

public class pauseMenu : MonoBehaviour 
{
    public GUISkin myskin;

    private Rect windowRect;
    private bool paused = true , waited = true;
    private float time = 0;

    private void Start()
    {
        windowRect = new Rect(Screen.width / 2 - 100, Screen.height / 2 - 100, 200, 200);
    }

    private void waiting()
    {
        waited = true;
    }

    private void Update()
    {
        if (waited)
            if (Input.GetKey(KeyCode.Escape) || Input.GetKey(KeyCode.P))
        {
            if (paused)
                paused = false;
            else
                paused = true;

            waited = false;
            Invoke("waiting",0.3f);
        }
        if(paused)time += Time.deltaTime;
        Debug.Log (time);
    }

    private void OnGUI()
    {
        if (paused)
            windowRect = GUI.Window(0, windowRect, windowFunc, "Pause Menu");
    }

    private void windowFunc(int id)
    {
        if (GUILayout.Button("Resume"))
        {
            paused = false;
        }
        if (GUILayout.Button ("Restart")) 
        {
            Application.LoadLevel("LEVEL 1");
        }
        if (GUILayout.Button("Quit"))
        {
            Application.LoadLevel("Main Menu");
        }
    }
}
