刚刚入坑Unity时，还没什么感觉，用久了Unity自带的日志系统，有时候全屏化后看日志是真的麻烦，于是就产生了自己写一个Pro版的想法，可能有些不完善，勤劳的小伙伴可以再去升级。下面开始动手。
因为Unity的一些机制，我们需要把我们的工具以DLL的形式调用。具体原因是因为不封装成DLL的话，进行打印追踪时会直接追踪到我们的工具内部，而不是调用工具打印的那个位置。
新建一个C#类库工程 我用的是vs2017 其他版本差不多 .net框架版本选择3.5的试了好几次
然后你会得到这样的一个工程
然后去引用UnityEngine.dll 具体目录为xxxx\Unity\Editor\Data\Managed\UnityEngine.dll
然后代码复制过去

}修改项目属性项目为
生成解决方案即可
新建Unity工程测试一下
在Unity工程下创建Plugins文件夹，然后将刚刚生成的DLL放进去
然后编写辅助脚本（实例化Log对象）自己看着弄哈
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Blm;
public class BlmLog : MonoBehaviour {
public Texture p1, p2, p3;
private void Awake () {
if(Log.User == null){
GameObject log = new GameObject ("MyLog");
log.AddComponent<Log> ();
DontDestroyOnLoad (log);
}
Log.IsStop = false;//是否暂停
Log.IsShowWindow = true;//是否直接显示窗口
Log.IsBackgroundOutput = false;//是否后台输出
Log.Logimage = this.p1;//常规Log图标
Log.Errorimage = this.p2;//错误Log图标
Log.rect = new Rect(Screen.width/2 - (Screen.width/2)/2,10,Screen.width/2,Screen.height - Screen.height / 3);//窗口位置与大小
//。。。
}
}
把脚本挂到随便一个对象上运行
Test测试脚本
using System.Collections;
using System.Collections.Generic;
using Blm;
using UnityEngine;
public class Test : MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetMouseButtonUp(0))//鼠标左击触发
{
Log.Show("日志1");
}
if (Input.GetMouseButtonUp(1))
{
Log.ShowError("日志2");
}
if (Input.GetMouseButtonUp(2))
{
Log.ShowImportant("日志3");
}
}
}
