为毛要实现这个工具?

1. 在我小时候,每当游戏在真机运行时,我们看到的日志是这样的。

   没高亮啊,还有乱七八糟的堆栈信息,好干扰日志查看,好影响心情。

2. 还有就是必须始终连着usb线啊，我想要想躺着测试。。。 以上种种原因,QConsole诞生了。

如何使用?

使用方式和QLog一样,在初始化出调用,简单的一句。

QConsole.Instance();
复制代码

就好了,使用之后效果是这样的。

在Editor模式下,F1控制开关。

在真机上需要在屏幕上同时按下五个手指就可以控制开关了。(本来考虑11个手指萌一下的)。

实现思路:

1.首先要想办法获取Log,这个和上一篇介绍的QLog一样,需要使用Application.logMessageReceived这个api。

2.获取到的Log信息要存在一个Queue或者List中,然后把Log输出到屏幕上就ok了。

3.输出到屏幕上使用的是OnGUI回调和 GUILayout.Window这个api, 总共三步。

贴上代码:

QFPSCounter

using UnityEngine;
using System.Collections;namespace QFramework {/// <summary>/// 帧率计算器/// </summary>public class QFPSCounter{// 帧率计算频率private const float calcRate = 0.5f;// 本次计算频率下帧数private int frameCount = 0;// 频率时长private float rateDuration = 0f;// 显示帧率private int fps = 0;public QFPSCounter(QConsole console){console.onUpdateCallback += Update;console.onGUICallback += OnGUI;}void Start(){this.frameCount = 0;this.rateDuration = 0f;this.fps = 0;}void Update(){++this.frameCount;this.rateDuration += Time.deltaTime;if (this.rateDuration > calcRate){// 计算帧率this.fps = (int)(this.frameCount / this.rateDuration);this.frameCount = 0;this.rateDuration = 0f;}}void OnGUI(){GUI.color = Color.black;GUI.Label(new Rect(80, 20, 120, 20),"fps:" + this.fps.ToString());        }}}

QMemoryDetector

using UnityEngine;
using System.Collections;namespace QFramework {/// <summary>/// 内存检测器，目前只是输出Profiler信息/// </summary>public class QMemoryDetector {private readonly static string TotalAllocMemroyFormation = "Alloc Memory : {0}M";private readonly static string TotalReservedMemoryFormation = "Reserved Memory : {0}M";private readonly static string TotalUnusedReservedMemoryFormation = "Unused Reserved: {0}M";private readonly static string MonoHeapFormation = "Mono Heap : {0}M";private readonly static string MonoUsedFormation = "Mono Used : {0}M";// 字节到兆private float ByteToM = 0.000001f;private Rect allocMemoryRect;private Rect reservedMemoryRect;private Rect unusedReservedMemoryRect;private Rect monoHeapRect;private Rect monoUsedRect;private int x = 0;private int y = 0;private int w = 0;private int h = 0;public QMemoryDetector(QConsole console){this.x = 60;this.y = 60;this.w = 200;this.h = 20;this.allocMemoryRect = new Rect(x, y, w, h);this.reservedMemoryRect = new Rect(x, y + h, w, h);this.unusedReservedMemoryRect = new Rect(x, y + 2 * h, w, h);this.monoHeapRect = new Rect(x, y + 3 * h, w, h);this.monoUsedRect = new Rect(x, y + 4 * h, w, h);console.onGUICallback += OnGUI;}void OnGUI(){GUI.Label(this.allocMemoryRect, string.Format(TotalAllocMemroyFormation, Profiler.GetTotalAllocatedMemory() * ByteToM));GUI.Label(this.reservedMemoryRect, string.Format(TotalReservedMemoryFormation, Profiler.GetTotalReservedMemory() * ByteToM));GUI.Label(this.unusedReservedMemoryRect, string.Format(TotalUnusedReservedMemoryFormation, Profiler.GetTotalUnusedReservedMemory() * ByteToM));GUI.Label(this.monoHeapRect,string.Format(MonoHeapFormation, Profiler.GetMonoHeapSize() * ByteToM));GUI.Label(this.monoUsedRect,string.Format(MonoUsedFormation, Profiler.GetMonoUsedSize() * ByteToM));}}}
复制代码

注意事项:

1. 和上一篇介绍的QLog一样,需要依赖上上篇文章介绍的QApp。

2. QConsole初步实现来自于开源Unity插件Unity-WWW-Wrapper中的Console.cs.在此基础上添加了ScrollToBottom选项。因为这个插件的控制台不支持滚动显示Log,需要拖拽右边的scrollBar,很不方便。

3. Unity-WWW-wrapper非常不稳定,建议大家不要使用。倒是感兴趣的同学可以研究下实现,贴上地址:https://www.assetstore.unity3d.com/en/#!/content/19116。
