Unity3D 帧数修改

1、在Quality(质量)设置里把帧数设定关闭之后才能在代码中修改游戏运行的帧数

 

2、在Unity中新建脚本UpdateFrame.cs ，编写如下代码

using UnityEngine;
using System.Collections;

/// <summary>
/// 功能：修改游戏FPS
/// </summary>
public class UpdateFrame : MonoBehaviour
{
    //游戏的FPS，可在属性窗口中修改
    public int targetFrameRate = 300;
    
    //当程序唤醒时
    void Awake ()
    {
        //修改当前的FPS
        Application.targetFrameRate = targetFrameRate;
    }
    
}

3、把该代码及ShowFPS.js绑定在层次视图的任一GameObject上，运行游戏，即可以Game视图中看到当前的FPS，同时可修改targetFrameRate变量来观看结果

ShowFPS.js代码

@script ExecuteInEditMode

 

private  var  gui : GUIText;

 

private  var  updateInterval = 1.0;

private  var  lastInterval : double ; // Last interval end time

private  var  frames = 0; // Frames over current interval

 

function Start()

{

     lastInterval = Time.realtimeSinceStartup;

     frames = 0;

}

 

function OnDisable ()

{

     if  (gui)

         DestroyImmediate (gui.gameObject);

}

 

function Update()

{

#if !UNITY_FLASH

     ++frames;

     var  timeNow = Time.realtimeSinceStartup;

     if  (timeNow > lastInterval + updateInterval)

     {

         if  (!gui)

         {

             var  go : GameObject = new  GameObject( "FPS Display" , GUIText);

             go.hideFlags = HideFlags.HideAndDontSave;

             go.transform.position = Vector3(0,0,0);

             gui = go.guiText;

             gui.pixelOffset = Vector2(5,55);

         }

         var  fps : float  = frames / (timeNow - lastInterval);

         var  ms : float  = 1000.0f / Mathf.Max (fps, 0.00001);

         gui.text = ms.ToString( "f1" ) + "ms "  + fps.ToString( "f2" ) + "FPS" ;

         frames = 0;

         lastInterval = timeNow;

     }

#endif

}
