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
|
||||
```
|
||||
|
||||
- 用godot你能感觉我能把控底层,我能把控每一行代码的底层细节,这个是程序员的浪漫,godot在国外比较火是有原因的

# 为使用godot我应该选择什么语言,C# or GDScript
|
||||
|
||||
- gds更加简单,支持的更加完整,而且是脚本可以热更新
|
||||
- C#很多库用不了,有限制,如果是为了性能可以在godot中使用C++
|
||||
- C#对于godot来说比较重,推荐gds
|
||||
- unity在很久之前也同时支持过js和C#,最后放弃了js,主要是因为unity是mono和C#非常友好
|
||||
- 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
