Node.js聊天机器人生成相同的随机数？

Question

This is for Twitch.tv. If someone types !random in the chat, the bot will reply with a random number from 1-100. But it's currently only returning the same number (eg 58) over and over again. Any help with this? Cheers.

var rand = Math.floor(Math.random() * 100);

var canSendMessage = true;
client.on('chat', function(channel, user, message, self) {
if(message === "!random" && canSendMessage ) {
canSendMessage = false;

client.say("shred", rand.toString());

setTimeout(function(){ canSendMessage = true }, 2000);
}});

I haven't used the Twitch API before, but I'd imagine you need to do something like this:

var canSendMessage = true;
client.on('chat', function(channel, user, message, self) {
    if (message === "!random" && canSendMessage) {
        canSendMessage = false;
        var rand = Math.floor(Math.random() * 100);
        client.say("shred", rand.toString());
        setTimeout(function() { canSendMessage = true }, 2000);
    }
});

Notice how Math.random() is called for each chat message received, to generate a new random number each time.
