一、Unity 打印日志
Unity中，在其编辑器上有个专门的Console，快捷键：shift + Ctrl+ c 。
代码中的Debug.Log("this is a test");就会打印到这里。
但是在打包后，只有从Log中找到，能不能找到一个可以实时显示的工具呢？
很明显，必须有啊！！要不写这篇不就是瞎扯了么？！！
我辗转腾挪，到处寻觅，我肯定不是第一个有这个想法的人。
终于有一天，我来到了七环！！！找到了几种方法，与君共享！！
二、我想有个控制台
之前说的Debug.Log();此函数是打印Unity控制台的。
好办，有高人已经重新把控制台给换了地方，打印到界面的控制台上。
就是类似控制台的一个界面。
先放结果图样：
1.问题来了，怎么实现的呢？
我给改了名字叫TestConsole.cs了，因为之前名字为Console,这样想我这样都在一个工程中为大家测试，容易造成混乱。
//#define USE_TESTCONSOLE
using System.Collections.G
using UnityE

/// &summary&
/// A console to display Unity's debug logs in-game.
/// &/summary&

/// &summary&

/// Setting this can be helpful if memory usage is a concern.
/// &/summary&
public bool restrictLogCount =
/// &summary&
/// Number of logs to keep before removing old ones.
/// &/summary&
public int maxLogs = 1000;
#endregion
readonly List&Log& logs = new List&Log&();
Vector2 scrollP
// Visual elements:
static readonly Dictionary&LogType, Color& logTypeColors = new Dictionary&LogType, Color&
{ LogType.Assert, Color.white },
{ LogType.Error, Color.red },
{ LogType.Exception, Color.red },
{ LogType.Log, Color.white },
{ LogType.Warning, Color.yellow },
const string windowTitle = "Console";
const int margin = 20;
static readonly GUIContent clearLabel = new GUIContent("Clear", "Clear the contents of the console.");
static readonly GUIContent collapseLabel = new GUIContent("Collapse", "Hide repeated messages.");
readonly Rect titleBarRect = new Rect(0, 0, 10000, 20);
Rect windowRect = new Rect(margin, margin, Screen.width - (margin * 2), Screen.height - (margin * 2));
void OnEnable()
#if UNITY_5
Application.logMessageReceived += HandleL
Application.RegisterLogCallback(HandleLog);
void OnDisable()
#if UNITY_5
Application.logMessageReceived -= HandleL
Application.RegisterLogCallback(null);
void Update()
if (Input.GetKeyDown(toggleKey))
visible = !
if (shakeToOpen && Input.acceleration.sqrMagnitude & shakeAcceleration)
void OnGUI()
if (!visible)
windowRect = GUILayout.Window(123456, windowRect, DrawConsoleWindow, windowTitle);

// Allow the window to be dragged by its title bar.
GUI.DragWindow(titleBarRect);
/// &summary&
/// Displays a scrollable list of logs.
/// &/summary&
void DrawLogsList()
scrollPosition = GUILayout.BeginScrollView(scrollPosition);
// Iterate through the recorded logs.
for (var i = 0; i & logs.C i++)
var log = logs[i];
// Combine identical messages if collapse option is chosen.
if (collapse && i & 0)
var previousMessage = logs[i - 1].
if (log.message == previousMessage)
GUI.contentColor = logTypeColors[log.type];
GUILayout.Label(log.message);
GUILayout.EndScrollView();
// Ensure GUI colour is reset before drawing other components.
GUI.contentColor = Color.
/// &summary&
/// Displays options for filtering and changing the logs list.
/// &/summary&
void DrawToolbar()
GUILayout.BeginHorizontal();
if (GUILayout.Button(clearLabel))
logs.Clear();
collapse = GUILayout.Toggle(collapse, collapseLabel, GUILayout.ExpandWidth(false));
GUILayout.EndHorizontal();
/// &summary&
/// Records a log from the log callback.
/// &/summary&
/// &param name="message"&Message.&/param&
/// &param name="stackTrace"&Trace of where the message came from.&/param&
/// &param name="type"&Type of message (error, exception, warning, assert).&/param&
void HandleLog(string message, string stackTrace, LogType type)
logs.Add(new Log
message = message,
stackTrace = stackTrace,
type = type,
TrimExcessLogs();
/// &summary&
/// Removes old logs that exceed the maximum number allowed.
/// &/summary&
void TrimExcessLogs()
if (!restrictLogCount)
var amountToRemove = Mathf.Max(logs.Count - maxLogs, 0);
if (amountToRemove == 0)
logs.RemoveRange(0, amountToRemove);
我在代码最前面添加了宏定义，使用的时候屏蔽此宏定义即可。
2.怎么使用呢？
恩。我写的使用很简单。
随便写个C#代码，在Update中测试的。
// Update is called once per frame
void Update ()
//DebugConsole.Log(" test s");
Debug.Log("Debug log
Console.WriteLine("this is Console Write line test ");
//DebugConsole.instance.AddMessage("this is instance AddMessage test by cartzhang", "warning");
//DebugConsole.Log("this is debug console log test cartzhang");
3.结果上面已经说明了。
这里就不重复了。
4.这怎么实现的呢？
原理很简单。写一个面板，往上面写字啊！
说下啊，这个有个切换按键，就是可以控制是否显示这个面板的，按键为BackQuote，你也可以修改，BackQuote这个键呢，在ESC按键的下面就是这个“～”。
三、这不是我想要的，我要显示在屏幕上。
我想要显示在控制台上，就是CMD出来的那样。
1. 直接写在屏幕上的代码
不过，我先赠送一个显示在屏幕上的。
这样我觉得大部分的人就会满足了，最起码不用自己写GUI .Label()了啊。
说明这个是国外友人好早之前写的，我只改变了其中某些不符合现在Unity 5 的语句，其他没有动。
还是代码：
/*==== DebugConsole.cs ====================================================
* Class for handling multi-line, multi-color debugging messages.
* Original Author: Jeremy Hollingsworth
* Based On: Version 1.2.1 Mar 02, 2006
* Modified: Simon Waite
* Date: 22 Feb 2007
* Modification to original script to allow pixel-correct line spacing
* Setting the boolean pixelCorrect changes the units in lineSpacing property
* to pixels, so you have a pixel correct gui font in your console.
* It also checks every frame if the screen is resized to make sure the
* line spacing is correct (T drag and let go in the editor
* and the text spacing will snap back)
* ::Drop in your standard assets folder (if you want to change any of the
* default settings in the inspector, create an empty GameObject and attach
* this script to it from you standard assets folder.
That will provide
* access to the default settings in the inspector)
* ::To use, call DebugConsole.functionOrProperty() where
* functionOrProperty = one of the following:
* -Log(string message, string color)
Adds "message" to the list with the
* "color" color. Color is optional and can be any of the following: "error",
* "warning", or "normal".
Default is normal.
* Clear() Clears all messages
* isVisible (true,false)
Toggles the visibility of the output.
Does _not_
* clear the messages.
* isDraggable (true, false)
Toggles mouse drag functionality
* =========================================================================*/

//DebugConsole.Log("this is debug console log test cartzhang");
3.结果如图
四、这还不是我想要的，我要显示在控制台上，就是CMD出来的那样。
好吧，你赢了！！
你往下看吧！
