Unity3D 帧数修改

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
}
