一个健壮的工程里面少不了各种拓展工具，好的拓展工具不仅可以方便开发，还能够赏心悦目，以前也写过许多的拓展工具，主要偏实用对工具的美术要求比较低（应该说是很难看），为了美化工具提高工具的可读性，接下来准备在拓展工具美化这一块用用力，并记载一下学习记录。

练习重点
- 基本组件的使用
- GUI布局
- 界面美化
- 内置Icon使用
- 内置GUIStyle使用
MEditorWindow
EditorWindow的派生类，准备做自定义窗口的基类，目前功能很少，后期持续补充
代码如下：
using UnityEditor;
using UnityEngine;
namespace S.Editor
{
public class MEditorWindow : EditorWindow
{
protected virtual void OnGUI()
{
EditorGUILayout.BeginHorizontal(EditorStyles.toolbar);
OnTitleGUI();
EditorGUILayout.EndHorizontal();
OnBodyGUI();
}
/// <summary>
/// 绘制标题区域
/// </summary>
protected virtual void OnTitleGUI()
{
}
/// <summary>
/// 绘制主体区域
/// </summary>
protected virtual void OnBodyGUI()
{
}
/// <summary>
/// 拷贝字符串到剪贴板
/// </summary>
protected void CopyString(string value)
{
TextEditor textEditor = new TextEditor();
textEditor.text = value;
textEditor.OnFocus();
textEditor.Copy();
}
}
}
EditorDemo0
