修改Unity的FPS
FPS是游戏运行的帧数，本文讲解如何修改Unity引擎的FPS。
步骤
1、在 Edit/Project Settings/Quality 质量设置里把帧数设定关闭，关闭之后才能在代码中修改游戏运行的帧数。
UpdateFrame.cs
2、在Unity中创建新脚本UpdateFrame.cs ，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
尝试修改
4、运行游戏，即可以Game视图中看到当前的FPS修改targetFrameRate变量，查看FPS的变化
ShowFPS.js
@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
}
