Unity Editor -Cubemap

一、创建我们的Editor脚本

using UnityEngine;
using UnityEditor;
public class ResizablePanels : EditorWindow
{
}

二、初始化窗口并且给标题起名

编辑器窗口需要初始化静态方法。 在这个方法中，我们将构建窗口并（可选）给它一个标题。 GetWindow（）是一个EditorWindow方法，它创建窗口（如果它不存在），或者查找并关注它（如果存在）。

using UnityEngine;
using UnityEditor;
public class ResizablePanels : EditorWindow
{
[ MenuItem( "Window/Resizable Panels")]
private static void OpenWindow()
{
ResizablePanels window = GetWindow< ResizablePanels>();
window. titleContent = new GUIContent( "Resizable Panels");
}
}

三、采用OnGUI（）创建两个矩形

为了在这个窗口中绘图，我们将使用OnGUI（）方法（是的，Unity自己的编辑器系统仍然使用旧的GUI系统，它可能不会长时间改变）。但首先，我们需要两个矩形来定义我们的面板。我还将在他们自己的方法中绘制这些面板，所以当我们处理它时，我们也应该添加这些方法。

using UnityEngine;
using UnityEditor;
public class ResizablePanels : EditorWindow
{
private Rect upperPanel;
private Rect lowerPanel;
[ MenuItem( "Window/Resizable Panels")]
private static void OpenWindow()
{
ResizablePanels window = GetWindow< ResizablePanels>();
window. titleContent = new GUIContent( "Resizable Panels");
}
private void OnGUI()
{
DrawUpperPanel();
DrawLowerPanel();
}
private void DrawUpperPanel()
{
}
private void DrawLowerPanel()
{
}
}

我们的编辑窗口开始形成。我们现在需要做的就是绘制面板并检查它们是否正常工作。GUILayout.BeginArea（Rect rect）将创建一个要绘制的矩形区域，GUILayout.EndArea（）标记结束。这些区域将定义我们的面板。我还要在这两个区域添加标签，以便我们可以看到它们的外观。

using UnityEngine;
using UnityEditor;
public class ResizablePanels : EditorWindow
{
private Rect upperPanel;
private Rect lowerPanel;
[ MenuItem( "Window/Resizable Panels")]
private static void OpenWindow()
{
ResizablePanels window = GetWindow< ResizablePanels>();
window. titleContent = new GUIContent( "Resizable Panels");
}
private void OnGUI()
{
DrawUpperPanel();
DrawLowerPanel();
}
private void DrawUpperPanel()
{
upperPanel = new Rect( 0, 0, position. width, position. height * 0.5f);
GUILayout. BeginArea( upperPanel);
GUILayout. Label( "Upper Panel");
GUILayout. EndArea();
}
private void DrawLowerPanel()
{
lowerPanel = new Rect( 0, position. height * 0.5f, position. width, position. height * 0.5f);
GUILayout. BeginArea( lowerPanel);
GUILayout. Label( "Lower Panel");
GUILayout. EndArea();
}
}

四、调节两个矩形的大小

using UnityEngine;
using UnityEditor;
public class ResizablePanels : EditorWindow
{
private Rect upperPanel;
private Rect lowerPanel;
private Rect resizer;
private float sizeRatio = 0.5f;
private bool isResizing;
private GUIStyle resizerStyle;
[ MenuItem( "Window/Resizable Panels")]
private static void OpenWindow()
{
ResizablePanels window = GetWindow< ResizablePanels>();
window. titleContent = new GUIContent( "Resizable Panels");
}
private void OnEnable()
{
resizerStyle = new GUIStyle();
resizerStyle. normal. background = EditorGUIUtility. Load( "icons/d_AvatarBlendBackground.png") as Texture2D;
}
private void OnGUI()
{
DrawUpperPanel();
DrawLowerPanel();
DrawResizer();
ProcessEvents( Event. current);
if ( GUI. changed) Repaint();
}
private void DrawUpperPanel()
{
upperPanel = new Rect( 0, 0, position. width, position. height * sizeRatio);
GUILayout. BeginArea( upperPanel);
GUILayout. Label( "Upper Panel");
GUILayout. EndArea();
}
private void DrawLowerPanel()
{
lowerPanel = new Rect( 0, ( position. height * sizeRatio) + 5, position. width, position. height * ( 1 - sizeRatio) - 5);
GUILayout. BeginArea( lowerPanel);
GUILayout. Label( "Lower Panel");
GUILayout. EndArea();
}
private void DrawResizer()
{
resizer = new Rect( 0, ( position. height * sizeRatio) - 5f, position. width, 10f);
GUILayout. BeginArea( new Rect( resizer. position + ( Vector2. up * 5f), new Vector2( position. width, 2)), resizerStyle);
GUILayout. EndArea();
EditorGUIUtility. AddCursorRect( resizer, MouseCursor. ResizeVertical);
}
private void ProcessEvents( Event e)
{
switch ( e. type)
{
case EventType. MouseDown:
if ( e. button == 0 && resizer. Contains( e. mousePosition))
{
isResizing = true;
}
break;
case EventType. MouseUp:
isResizing = false;
break;
}
Resize( e);
}
private void Resize( Event e)
{
if ( isResizing)
{
sizeRatio = e. mousePosition. y / position. height;
Repaint();
}
}
}
