+# godot界面介绍
+
+![Image text](image/godot-editor.PNG)
+
+### 侧面分栏（Dock）
+
+- 点击侧面分栏的右上角可以调整分栏的位置
+
+
+- 左侧面分栏具体包括：
+    1. 文件系统（FileSystem），显示了当前项目中所有的资源文件
+    2. 导入（Import），显示了文件系统分栏中所选资源文件的导入设置。
+    3. 场景（Scene），按照层级结构显示当前场景中的所有节点。
+
+
+- 右侧面分栏具体包括：
+    1. 属性（Inspector），显示了场景分栏中所选节点的属性。
+    2. 节点（Node），显示了与当前场景分栏中所选节点对应的一些“信息”。
+
+
+- 中间面板具体包括：
+    - 主工作区（Workspace）
+        - 2D，当在场景分栏中所选节点为2D类型时，会自动进入此工作区。
+        - 3D，当在场景分栏中所选节点为3D类型时，会自动进入此工作区。
+        - 脚本（Script），此工作区可以对当前项目中的脚本进行编辑。
+        - 资源库（AssetLib），可以搜索并浏览网站上的资源
+
+    - 底部面板（Bottom Panel）
+        - 隐藏
+
+
+- 与Unity和UE4不同的是：Godot这种布局关系当前是相对固定的，即它不能随意调整任意一个面板的位置或脱离成独立的窗口。虽然这看似是一个缺点，不过从某种程度上讲也让引擎变得更简单了。
+
+# godot的快捷键和界面基础操作
+
+- Q，选择，v移动锚点，shift + v 拖拽锚点
+- W，移动
+- R，旋转
+- S，缩放

 - godot和ue对比
     - 自主可控(避免被“卡脖子”)，从开源软件的角度分析，godot是游戏引擎界的Linux，ue和unity算是Windows
     - ue虽然开源源代码，但是代码量太大，历史包袱太重，不适合深入研究底层代码的人
-      ![Image text](engine-source.PNG)
+      ![Image text](image/engine-source.PNG)
 
 
 - godot的作者尽最大努力的减少第三方库的依赖，最终使其代码非常精简，适合学习
 - 源代码开源，不收费，unity和ue都是要收费的，ue超过100万美元触发5%的分成费用

 - 使用godot你既可以用GDScript去编写代码，也可以用C++去编写代码，还可以去改底层引擎代码
