Unity-3D 倒数计时器

脚本运行中是不断的将void OnGUI()循环运行
所以用到了bool变量来判断倒数计时器的是否运行

using UnityEngine;
using System.Collections;

public class Label : MonoBehaviour {

    private int frametime;
    public Texture img;
    private bool isclick = false;
    private bool tmp;

    void OnGUI()
    {
        GUIStyle sty = new GUIStyle();
        sty.normal.textColor = Color.green;
        sty.fontSize = 30;
        GUIStyle sty1 = new GUIStyle();
        sty1.normal.textColor = Color.yellow;
        sty1.fontSize = 20;
        sty1.normal.background = null;
        //sty.fontStyle = ;
        if (!isclick)
        {
            isclick = GUI.Button(new Rect(10, 10, 80, 80), "开始倒计时!",sty1);       
        }
        GUI.Label(new Rect(160, 50, 100, 20), frametime.ToString(),sty);
        if(isclick && frametime > 0)
        {
            frametime--;
        }
        if (frametime == 0)
        {
            GUI.Label(new Rect(10, 50, 380, 255), img);
            tmp = GUI.Button(new Rect(300, 10, 80, 50), "重新开始",sty1);
            if (tmp)
            {
                frametime = 1000;
                isclick = false;
            }
        }
        if(frametime > 0)
        {
            if( GUI.Button(new Rect(160, 10, 80, 30), "暂停",sty1))
            {
                isclick = false;
            }
           
                
        }
    }


    // Use this for initialization
    void Start () {
        frametime = 1000;      
    }
    
    // Update is called once per frame
    void Update () {
    
    }
}
