Unity3D FPS幀數修改

修改Unity的FPS

FPS是游戲運行的幀數，本文講解如何修改Unity引擎的FPS。

步驟

1、在 Edit/Project Settings/Quality  質量設置里把幀數設定關閉，關閉之后才能在代碼中修改游戲運行的幀數。

UpdateFrame.cs

2、在Unity中創建新腳本UpdateFrame.cs ，代碼

using UnityEngine;
using System.Collections;

/// <summary>
/// 功能：修改游戲FPS
/// </summary>
public class UpdateFrame : MonoBehaviour
{
    //游戲的FPS，可在屬性窗口中修改
    public int targetFrameRate = 300;
    
    //當程序喚醒時
    void Awake ()
    {
        //修改當前的FPS
        Application.targetFrameRate = targetFrameRate;
    }
    
}

3、把該代碼及ShowFPS.js綁定在層次視圖的任一GameObject上

嘗試修改

4、運行游戲，即可以Game視圖中看到當前的FPS修改targetFrameRate變量，查看FPS的變化

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
}
