问题描述
我正在尝试制作一个有趣的宾果游戏.我在很多地方寻找了一个独特的生成器,但似乎找不到一个.我已经尝试过制作自己的游戏,但是一旦它实际上命中了一个相同的数字,就会执行无限循环.我尝试了一个简单的代码,该代码理论上应该可以工作,但是由于某些原因,事情还是会通过.我该怎么办!?
I'm trying to make a bingo game for fun. I've looked in a lot of places for a unique generator but I can't seem to find one. I've tried to make my own,but once it actually hits a number that's the same it does an infinite loop. I've tried a simple code that in theory should work but for some reason things pass through. What can I do!?
var bc = [];
for (var i = 0; i < 5; i++) {
var r = Math.floor(Math.random()*20+1) + 0;
if(!(r in bc)){
bc.push(r);
}
else
{
i--;
}
}

推荐答案
它永远都不会.这样的算法运行时间越长,花费的时间就越长.您应该采用其他方法:
It never should. Such algorithms take longer the longer they run. You should take a different approach:
将所有可能的数字放入池中.绘制数字后,将其从池中删除.就像在现实生活中一样.
Put all possible numbers into a pool. Once you draw a number, remove it from the pool. Just like it's done in real life.
var pool = [1, 2, 3, 4, 5];
var getNumber = function () {
if (pool.length == 0) {
throw "No numbers left";
}
var index = Math.floor(pool.length * Math.random());
var drawn = pool.splice(index, 1);
return drawn[0];
};
