unity布局管理器
使用unity布局管理器轻松对关卡选择进行布局。
实现过程
- 准备普通按钮button设置字体和对应的sprite
- 设置父gameobject（levelbase） 再创建UI.image（selectbackground）布局背景和大小
- gameobject（gridcontent）添加 grid layout group（布局）组件和content size fitter组件（控制布局内按钮拉伸）
- 将准备的按钮置于gameobject的子类
- 给布局背景添加rectmask2D属性，可以遮盖多余的
-
给父类levelbase添加scroll rect组件，并将gridcontent放入其content属性下，将levelbackground设置在viewport属性下
-
levelbase设置脚本
用于读取关卡信息设置按钮的是否可以交互状态
