2D小游戏--猜对应卡牌(unity)

项目名称 guess_card_game

参考源码链接：
https://www.manning.com/books/unity-in-action

效果图预览

step1: 创建一个3D项目

step2: 修改2D相关设置

点击Edit/Project Settings 再选择Editor选项修改Default Behaviour Mode的Mode为2D

修改选项卡为2D模式

step3: 准备工作

创建需要的文件夹

记住场景名字

在Sprites文件夹下准备相应的图片

卡牌图案： 150*200px

卡背：能盖住卡牌即可

重置按钮：无要求

背景：无要求

step4: 相关代码
