 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
+游戏行业到最后都是C++，如果想把游戏当作自己的事业，那绝对不要满足在脚本上，游戏最后的优化都是基于硬件显卡之上的，只能用C++

 - godot使用C++去解释执行gds，这个时候对于godot来说比较重，推荐gds
 - 通过学习gds也可以学到一些编译原理的知识
 - godot不仅仅是一个游戏引擎，而且还是一个优质的学习资源

+因为刚开始的时候有点疑惑，godot的坐标系，原点既然在左上角。unity，cocos的2d原点都在左下角，左下角的2d坐标系感觉很复合习惯。
+unity的坐标系就很符合数学里面的象限，刚开始有点不适应。
+
+后来了解到，计算机屏幕是从左上角开始刷新的，2d坐标系左上角为原点可以屏幕坐标系吻合可以提升一点效率。  
+
+unity的2d坐标系虽然在左下角，但是unity的屏幕坐标系依然在左上角，不统一。
+虽然godot的2d坐标系在左上角的坐标系刚开始看不舒服，但是和屏幕坐标系吻合了，也算一种统一，就不需要untiy2d的那么多概念了，为godot点赞。
+
+因为单论平面内容制作，左上原点更符合视觉习惯，也更符合设计常识，比如ps。

+- 一个游戏可以包含多个场景，但是一个场景中必须有一个根节点，一个根节点可以包含多个不重名的子节点（unity的子节点可以同名），不同名更加符合习惯，为godot点赞。
