[游戏开发]Unity 自动化1.0(代码预制体生成到指定模块)

代码生成参考的 知乎【Unity】工具类系列教程—— 代码自动化生成！ - 知乎 (zhihu.com)https://zhuanlan.zhihu.com/p/30716595

操作流程:

一,创建模块

这里只写了创建UI预制体(模板UI)和对应脚本,而且放在一个文件夹下的.

正式项目一般一个模块会有多个脚本与之对应(数据,逻辑,UI),而且预制体和脚本也是分开存放;

具体看项目框架结构,这里只是一个模拟;

完成后会在对应目录生成一个.cs脚本和预制体

?预制体是通过模板预制体拷贝过去修改名字实现的，所以需要先有一个 模板UI，我的模板很简单，就一个canvas+mask+root

? ? ? ?

二，完成基本的脚本和预制体生成后，就可以去修改预制体（就是拼界面）；

这里要注意的是，需要用脚本访问的组件，名字需要根据组件类型特殊处理：

?界面弄好后，选中这个预制体，然后点击? ?[更新UI脚本]?

?这里的主逻辑就是参考的上面知乎帖子,里面写的很详细了,有疑问的可以跳过去看看;

三,实现你自己的界面逻辑... 是的,没有了

具体代码贴出来,写得有点凌乱, 后续有时间再优化吧...

加入了模块Data脚本的创建， 主要是CreateScript方法里的功能;?
