MenuItem(string itemName, bool isValidateFunction, int priority)

  • “itemName：菜单名称路径
  • “isValidateFunction：默认为false，如果为true则是一个验证函数,方法返回值必须是bool类型 表示是否可以执行这个命令
  • “priority：菜单项显示排序 如果相差间隔大于=11 就会有一个下划线
  • “快捷键 %（ctrl）、# (shift)、& (alt) _w(按下w, 单一字母)

Unity SerializedProperty和Target 区别

优点 缺点
SerializedProperty 1.可以多选
2.自动Undo
3.预制体重写
4.可以修改私有对象		 比较麻烦
Target 简单好用,跟调用对象一样 不能修改私有变量 不能多选 不能undo 修改对象后，要使用EditorUtility.SetDirty(target) 将target标记为脏状态，否则修改状态不会被记
