Unity实现简易日志输出功能

2020年03月09日  | 移动技术网IT编程  | 我要评论

在使用unity中的debug.log()进行日志输出时很不方便，在打包出来的可执行文件中没有办法看到输出，所有就想自己实现一个简易的日志输出功能，可以输出到日志文件，因为能力实在是不够，所以有错误和不合理的地方，还请各位老师指点一下，谢谢啦

1.日志记录器接口

public interface ilogger
{
 void log(string condition, string stacktrace, unityengine.logtype type);
}

2.日志文件记录器

using system;
using unityengine;
using system.io;
 
public class filelogger : ilogger
{
 private readonly string path;
 
 /// <summary>
 /// 构造方法
 /// </summary>
 /// <param name="isclear">是否清空原有的日志</param>
 public filelogger(bool isclear = false)
 {
  switch (application.platform)
  {
   case runtimeplatform.android:
    path = path.combine( application.persistentdatapath,"log.txt");
    break;
   case runtimeplatform.windowsplayer:
    path = path.combine(application.datapath, "log.txt");
    break;
   case runtimeplatform.windowseditor:
    path = path.combine(application.datapath, "log.txt");
    break;
   case runtimeplatform.iphoneplayer:
    path = path.combine(application.persistentdatapath, "log.txt");
    break;
   case runtimeplatform.osxeditor:
    break;
   default:
    break;
  }
 
  if (isclear)
  {
   if (file.exists(path))
   {
    file.delete(path);
   }
  }
 }
 
 public void log(string condition, string stacktrace, logtype type)
 {
  using (streamwriter sw = new streamwriter(path, true, system.text.encoding.utf8))
  {
   string msg = string.format("[{0}] {1}: {2}\n{3}", getnowtime(), type, condition, stacktrace);
   sw.writeline(msg);
  }
 }
 
 
 #region tool method
 private string getnowtime()
 {
  return datetime.now.tostring("yyyy/mm/dd hh:mm:ss");
 }
 #endregion
}

3.日志系统管理类 

using system;
using unityengine;
 
public class logsys
{
 private static ilogger logger;
 public static ilogger logger
 {
  get { return logger; }
 }
 
 public bool isopen
 {
  get { return debug.unitylogger.logenabled; }
 }
 
 private logsys() { }
 
 /// <summary>
 /// 初始化
 /// </summary>
 /// <param name="_logger">日志输出器</param>
 /// <param name="isopen">是否开启日志输出</param>
 public static void init(ilogger _logger, bool isopen = true)
 {
  init(isopen);
  logger = _logger;
  enable();
 }
 
 public static void init(bool isopen = true)
 {
  debug.unitylogger.logenabled = isopen;
 }
 
 /// <summary>
 /// 过滤器
 /// </summary>
 /// <param name="logtype">需要显示的日志类型</param>
 public static void filter(logtype logtype = logtype.log)
 {
  debug.unitylogger.filterlogtype = logtype;
 }
 
 public static void enable()
 {
  if (logger != null)
  {
   application.logmessagereceived += logger.log;
  }
 }
 
 public static void disable()
 {
  if (logger != null)
  {
   application.logmessagereceived -= logger.log;
  }
 
 }
}

4.测试 

using system;
using system.collections;
using system.collections.generic;
using system.io;
using unityengine;
using unityengine.ui;
 
public class test : monobehaviour
{
 public text logtext;
 
 void awake()
 {
  logsys.init(new filelogger());
 }
 
 void update()
 {
  if (input.getkeydown(keycode.q))
  {
   debug.log("my name is blinkedu.");
  }
 
  if (input.getkeydown(keycode.w))
  {
   debug.logwarning("my name is blinkedu.");
  }
 
  if (input.getkeydown(keycode.e))
  {
   debug.logerror("my name is blinkedu.");
  }
 }
 
 private void ondestroy()
 {
  logsys.disable();
 }
}
