我们在开发中,往往会觉得unity自带的日志系统不是那么好用,比如,不能筛选日志,不能打印在屏幕上,想生成自己的日志文件,等等等等的需求,这时候就需要自己来扩展编辑器的相关功能了。
我这里实现的需求比较简单,就是给日志加了个key,可以根据这个key来对暂时不需要显示的日志进行过滤,还有就是将我们的日志打印到屏幕上去。
打印屏幕的类参考了由 Jeremy Hollingsworth 和 Simon Waite 这2人写的一个 DebugConsole.cs 类,不过他们2个的版本实在是太早了,而且还有错误和啰嗦的地方,有兴趣的话你可以去搜来看看。外加老外真的很喜欢用while循环呀,好多能用for的地方也是while,是因为这样写字比较少吗?看来大家都是懒癌晚期患者,(:зゝ∠)
一直犯懒,终于把它给写了。。。有时间我也给它扔到 github 上去。。。
外加如果想要输出日志文件,或者其它什么功能的,你就自己加就好了,我当前的需求还是挺简单的~
效果如图:

using GameFramework;
public class Test : MonoBehaviour
{
public bool screenDisplay = false;
// Use this for initialization
void Start()
{
DebugMgr.Log("开始了");
}

void OnGUI()
{

{

DebugMgr.Log(log);
DebugMgr.LogWarning(log);
DebugMgr.LogError(log);
++m_count;
}
}
}
友情提示一下,你可能发现了,现在你左键点一下 Console 窗口下的日志,系统会给你跳转到 DebugMgr 类里,而不是真正打日志的地方,想要解决这个问题也很简单。你就把这2个类编译封装成一个单独的c#类库项目,生成dll后,再导入项目中就可以了,这样 unity 在追踪程序的堆栈调用时,跳转的位置就会指向你真正打日志的地方了,轻松又愉快~
