一:前言
对于面板赋值或Find绑定UI组件,我们可以使用一种工具化的方式去自动生成代码并绑定对象,增加效率
分为logic和view,view层是UI界面上的组件,每次都会自动生成并覆盖,logic层是逻辑
二:使用
例如一个UI界面,我们只需要做成预制体并在Project下右键预制体,选择AutoGen/Create View则会自动生成view和logic两个脚本,logic是我们要编写逻辑的脚本,view是每次都会自动生成并覆盖的脚本
三:说明
——以下几个路径都是可以自定义的(view和logic生成的路径、view和logic模版文件的路径)
——可以自定义忽略的组件类型列表文章来源:https://www.toymoban.com/news/detail-509736.html
——只会生成对象名带下划线的文章来源地址https://www.toymoban.com/news/detail-509736.html
