游戏开发学习日志——捡苹果DEMO

emm有一个BUG：level>10后出现的第二棵树，苹果掉落间隔没整好……不管了 : P 反正也没人玩。

昨天提到为了测试，写了一个……我也不知道干什么的测试工程。

今天就补充了一下，稍微能玩一下的游戏DEMO。

好吧……虽然这似乎也没什么可以玩的。

本来想做一个网络排行榜……但涉及到Socket通信，就没去为了这个DEMO搞。

（其实后来发现好像也可以用php读取MQSQL数据，然后用Unity加载PHP的返回数据……不过懒得搞了……）

这个就是一个很无聊的捡苹果游戏吧……每掉落一个苹果（没接到），就会life-1。life归零时游戏结束。

会有一个最高分（仅本地存储）

游戏链接：捡苹果

食用方式：开袋即食。篮子会跟随光标移动。（移动端即触碰位置）

开发引擎：Unity3D

引擎版本：2019.2.17f1

编程语言：C#

该工程基于webGL，部分浏览器可能不支持。移动端可能会弹出性能警示窗口（选择继续即可。）

核心代码：

……先丢个包把……
