本文的主要目的是在将Unity项目发布成APK后，在APK的操作界面方便查看应用中的LOG信息，以方便调试
实现的方式主要是利用Unity自带的Debug.Log()方法再次封装，使用GUI的API将自己的LOG信息显示在上层界面
闲话不多说，直接上代码：
这个脚本主要是用来接收项目中打印的LOG信息
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Text;
public class GameDebugLog : System.Object
{
/// <summary>
/// Log level .定义LOG的类型：正常、警告、错误、异常
/// </summary>
public enum LogLevel : byte
{
/// <summary>
/// The normal.
/// </summary>
Normal = 0,
/// <summary>
/// The warning.
/// </summary>
Warning,
/// <summary>
/// The error.
/// </summary>
Error,
/// <summary>
/// The exception.
/// </summary>

}
/// <summary>

{
OutputLog(LogLevel.Normal, msg, objs);
}

public static void LogWarning(string msg, params object[] objs)
{
OutputLog(LogLevel.Warning, msg, objs);
}
/// <summary>
/// Logs the error.
/// </summary>
/// <param name="msg">Message.</param>
/// <param name="objs">Objects.</param>
public static void LogError(string msg, params object[] objs)
{
OutputLog(LogLevel.Error, msg, objs);
}
/// <summary>

public static void LogException(System.Exception e)
{
OutputExceptionLog(e);
}
/// <summary>

/// </summary>
public class LogContent
{

public LogLevel Level { get; set; }
}

public static void AddLogCentent(LogLevel level, string msg)
{
if (logs == null) logs = new List<LogContent>();
if (logs != null)
{
if (logs.Count > 20) logs.RemoveAt(0);
LogContent log = new LogContent();
log.Msg = msg;
log.Level = level;
logs.Add(log);
}
}
public static bool isEditor = Application.isEditor;
/// <summary>
/// Outputs the log.
/// </summary>
/// <param name="level">Level.</param>
/// <param name="msg">Message.</param>
/// <param name="objs">Objects.</param>
public static void OutputLog(LogLevel level, string msg, params object[] objs)
{
StringBuilder sb = new StringBuilder();
sb.AppendFormat(msg, objs);
#if DEBUG_LOG_EDITOR
if (Application.isPlaying && !isEditor)
#else
if (Application.isPlaying)
#endif
{
AddLogCentent(level, sb.ToString());
}
else
{
if (level == LogLevel.Normal)
Debug.Log(sb.ToString());
else if (level == LogLevel.Warning)
Debug.LogWarning(sb.ToString());
else if (level == LogLevel.Error)
Debug.LogError(sb.ToString());
}
}
/// <summary>

public static void OutputExceptionLog(System.Exception e)
{
#if DEBUG_LOG_EDITOR
if (Application.isPlaying && !isEditor)
#else
if (Application.isPlaying)
#endif
{
StringBuilder sb = new StringBuilder();
sb.AppendFormat("{0} \n{1}", e.Message, e.StackTrace);
AddLogCentent(LogLevel.Exception, sb.ToString());
}
else
{
Debug.LogError(e);
}
Debug.LogError(e);
}
/// <summary>
/// The log position.
/// </summary>
public static Vector2 logPos;
/// <summary>
/// The log rect.
/// </summary>
public static Rect logRect;
/// <summary>

/// </summary>
public class LevelSetting
{
/// <summary>
/// Gets or sets the title.
/// </summary>

public string Title { get; set; }
/// <summary>

}
这个方法主要是在你的主类中进行调用，使用的是Unity的生命周期方法
public void OnGUI()
{
if (!Application.isPlaying) return;
if (levelSettings == null)
{
levelSettings = new Dictionary<GameDebugLog.LogLevel, GameDebugLog.LevelSetting>();
levelSettings[GameDebugLog.LogLevel.Normal] = new GameDebugLog.LevelSetting();
levelSettings[GameDebugLog.LogLevel.Normal].Title = "Normal: ";
levelSettings[GameDebugLog.LogLevel.Normal].TitleColor = Color.blue;
levelSettings[GameDebugLog.LogLevel.Warning] = new GameDebugLog.LevelSetting();
levelSettings[GameDebugLog.LogLevel.Warning].Title = "Warning: ";
levelSettings[GameDebugLog.LogLevel.Warning].TitleColor = new Color(1f, 0.5f, 0f, 1f);
levelSettings[GameDebugLog.LogLevel.Error] = new GameDebugLog.LevelSetting();
levelSettings[GameDebugLog.LogLevel.Error].Title = "Error: ";
levelSettings[GameDebugLog.LogLevel.Error].TitleColor = new Color(1f, 0f, 0f, 1f);
levelSettings[GameDebugLog.LogLevel.Exception] = new GameDebugLog.LevelSetting();
levelSettings[GameDebugLog.LogLevel.Exception].Title = "Exception: ";
levelSettings[GameDebugLog.LogLevel.Exception].TitleColor = new Color(1f, 0f, 0.5f, 1f);
GameDebugLog.logPos = Vector2.zero;
GameDebugLog.logRect = new Rect(Screen.width - 402, Screen.height - 268, 400, 266);
}
Color backgroundColor = GUI.backgroundColor;
Color oldContentColor = GUI.contentColor;
GUI.backgroundColor = new Color(0.5f, 0.0f, 0.0f, 0.5f);
GUI.Box(GameDebugLog.logRect, "");
GUILayout.BeginArea(GameDebugLog.logRect);
GameDebugLog.logPos = GUILayout.BeginScrollView(GameDebugLog.logPos, GUILayout.Width(400), GUILayout.Height(266));
if (GameDebugLog.logs != null)
{
for (int i = 0, imax = GameDebugLog.logs.Count; i < imax; ++i)
{
GUI.contentColor = levelSettings[GameDebugLog.logs[i].Level].TitleColor;
//GUILayout.BeginHorizontal();
GUILayout.Label(levelSettings[GameDebugLog.logs[i].Level].Title, GUILayout.Width(80));
GUI.contentColor = Color.green;
GUILayout.Label(GameDebugLog.logs[i].Msg);
//GUILayout.EndHorizontal();
}
}
GUILayout.EndScrollView();
GUILayout.EndArea();
GUI.contentColor = oldContentColor;
GUI.backgroundColor = backgroundColor;
}
显示效果如下图：
在项目中可以通过这样的方式方便定位问题所在，希望也能方便各位开发大大哦！
