我正在尝试学习JavaScript以及如何使用Discord提供的开发人员API。
我确实相信到目前为止我想要的一切都可以正常工作，除了我想创建一个像数据库的工作原理一样。桌上的每个播放器都有一个唯一的ID密钥。我不确定如果不使用DB。
是否可以使用。[index.js]

[我的问题]
这两个文件中唯一真正重要的部分是在index.js中，在谈到玩家何时离开的行中。所以！离开。
我遇到了一个玩家打字的问题！离开，两个人都会离开。那是我用来修复它的解决方案。
我无法让它仅用于键入该命令的人。
示例：
人一种类型！加入
玩家在线= [Playera]
Person B类型！加入
玩家在线= [Playera，PlayerB]
玩家A类型！离开
玩家在线= [[]，playerb]
它始终将一个空数组插入现场。所以我所做的就是将用户上一个名称及其数组ID填充。
我想要的是，以便它完全删除了该人的数组并删除了空地。
我也想知道是否有可能每次有人类型！加入！我都可以将它们插入一个具有多维的新数组中，并为每个播放器具有ID，以便当我输入时！在线，它将显示
[[[0，playera]，[1，playerb]]。就像一个数据库一样，如果需要，我总是可以看到他们的索引。
到目前为止我拥有的东西：https://i.stack.imgur.com/c1ggn.png
它仅在离开后跟踪最后一个索引。如何使其显示在线玩家的当前索引？
使用FindIndex（）在数组中找到名称的位置。然后使用splice（）方法从数组中删除值。您无需将其用于循环，因为FindIndex会运行类似的循环。
var playerIndex = playersName.findIndex(function(index) {
return index === tempLeave
})
playersName.splice(playerIndex, 1)
阅读了问题的第二部分后，我认为您应该在数组中创建对象。一个例子是：
[
{
playerName: "Foo",
id: indexNumber,
isOnline: true
},
{
playerName: "Bar",
id: indexNumber,
isOnline: true
}
]
当某人加入时，您检查他们的名称是否已分配给对象（您可以在此处再次使用FindIndex）。如果不是，您创建了一个新播放器，否则您将更改iSONLINE属性为true。我确定这是存储用户信息的最佳方法，但它可能对您有用。
