unity3d 代码修改帧数 quality需要改什么意思

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

}
