unity3d中的帧数使用的时候是怎样修改的呢?现在我们就来学习学习。

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
}
