[MCBE] 红包/抽奖系统 (微信红包算法)
///提醒: 此指令系统不是随随便便粘贴复制就能做成的，您需要拥有一定的指令与数学基础。
///使用之前，先确保你有一个名为Redpacket的记分板或着其他名字的记分板(需要把指令中大写的"Redpacket"改成记分板名)。

2链: times=1取int余数
/scoreboard players test times Redpacket 1 1

///int为输入值，times为次数，random值为输出值
///算法讲解
--/如果random=0，times≥2，在2^31-1整数极限中取random值，计算(int/times)*2值作为operation范围，random/operation取余数，若余数大于0则输出。
--/如果random=0，times=1，将int与random对调并将times重置至0。

4链: 启动红包分发
///该指令链设定int=1000 times=10。可自定义分发数量，次数，如何分发。仅供参考。
///注: int值要大于(times+1)值。否则可能会random计算出一个超级大数(random/0取余，没有数学意义，不能正常触发)
