Unity之Update与FixedUpdate区别

下面这段代码演示游戏暂停

using UnityEngine;
using System.Collections;

public class GamePauseTest : MonoBehaviour
{
    public float moveSpeed = 2.0f;

    void Update ()
    {
        //move
        transform.Translate (new Vector3 (0, 0, moveSpeed * Time.deltaTime));
    }
 
    void OnGUI ()
    {

        if (GUI.Button (new Rect (140, 0, 100, 50), "暂停")) {
            Time.timeScale = 0;
        }

        if (GUI.Button (new Rect (280, 0, 100, 50), "继续")) {
            Time.timeScale = 1;
        }
    }
}
