问题描述
我如何做到..
- 80%的时间会说
sendMessage("hi");
- 5%的时间会说
sendMessage("bye");
- 以及15%的时间会说
sendMessage("Test");
- 80% of the time it will say
sendMessage("hi");
- 5 % of the time it will say
sendMessage("bye");
- and 15% of the time it will say
sendMessage("Test");
它必须与Math.random()做些事情吗? 像
Does it have to do something with Math.random()? like
if (Math.random() * 100 < 80) {
sendMessage("hi");
}
else if (Math.random() * 100 < 5) {
sendMessage("bye");
}
推荐答案
是的,Math.random()
是实现此目的的绝佳方法.您要做的是计算一个随机数,然后根据该数字做出决定:
Yes, Math.random()
is an excellent way to accomplish this. What you want to do is compute a single random number, and then make decisions based on that:
var d = Math.random();
if (d < 0.5)
// 50% chance of being here
else if (d < 0.7)
// 20% chance of being here
else
// 30% chance of being here
这样,您就不会错过任何可能性.
That way you don't miss any possibilities.
