我有一个如下所示的条目:
{
"__v": 10,
"_id": "50f8050ed714645500000002",
"sid": "DI7gZ0sprJ",
"lines": [
{
"text": "Well that's what some people say anyway",
"_id": "50f80526d714645500000003",
"user": "Player456"
},
{
"text": "They're people just like the rest of us",
"_id": "50f805925543712caf000005",
"user": "Player123"
},
],
"title": "Test",
"maxlines": 0
}
并有一个如下所示的 socket.io 脚本:
socket.on('sendchat', function (data) {
Story.findOne({ sid: socket.room }, function(err, story){
if (err) {
console.log(err);
}
else if(story == null) {
console.log(err);
}
else {
io.sockets.in(socket.room).emit('updatechat', socket.username, data);
story.maxlines = story.maxlines - 1;
if (story.maxlines == 0) {
// End Game Script - Redirect to view page
io.sockets.in(socket.room).emit('gameover', slugs(story.title), socket.room);
}
//Save Story to DB
story.lines.push({
user: socket.username,
text: data
});
story.save(function(err, story){
if (err) {
console.log(err);
}
else {
console.log("Story Updated");
}
});
};
});
});
有没有办法可以检查 socket.username 是否等于已输入的最新行上的用户?
例如上面的 Player123 是最后一个进入一行,所以如果 Player123 再次尝试它只会发出一个错误,但是如果 Player456 进入一行,那么 Player123 可以再次
我正在尝试创建一个简单的回合制游戏,该游戏会检查以确保一个人在轮不到他们时不能进入
