1、效果展示
功能简述：点击开始抽奖按钮，进行抽奖，（可以外部修改的内容：每个奖品中奖的中奖的概率，奖品内容，抽奖次数，规则内容）抽奖次数小于0时，不能继续抽奖，点击右侧幸运抽奖按钮才能刷新次数，再次抽奖。点击查看规则按钮可以查看规则。
2、UI布局
将整个界面分为左右两部分，左边是抽奖部分，右边是规则和标题部分，把全部的脚本都挂载在Canvas上，然后将对应的内容赋值即可。

</Info>4、外部修改内容
1、规则文本：放在StreamingAssets中的ContentTxt中，命名为0，格式为文本文档格式
2、奖品内容：放在StreamingAssets中的image中，名称为”n-name“,n是指数字，因为读取图片的时候是按顺序读取的，不加这个数字可能会让奖品顺序乱了，name是指奖品的名称，名称也会在程序中显示
3、抽奖概率和次数：放在StreamingAssets中的ConfigFile中，注意8个数的概率之和为100.
