我怎样才能检查球员是否已经在另一张桌子/房间里了？- Lua

Question

我有一个名为：Rooms的表/字典，当客户想要加入一个房间时，我检查房间UID是否匹配：Rooms[i]["UID"] == Data，如果UID匹配，我检查播放机是否已经在房间中，如果没有，我会将播放机添加到他们想要加入的特定房间，但我有一些问题。

local Rooms = {
    [1] = {
        ["Name"] = "test1",
        ["Players"] = {},
        ["UID"] = game:GetService("HttpService"):GenerateGUID(true)
    },
    [2] = {
        ["Name"] = "test2",
        ["Players"] = {},
        ["UID"] = game:GetService("HttpService"):GenerateGUID(true)
    }
}

RemoteEvent.OnServerEvent:Connect(function(Player, Key, Data)
    if Key == "Join" then
        for i = 1, #Rooms do
            if Rooms[i]["UID"] == Data then
                if #Rooms[i]["Players"] > 0 then
                    for a = 1, #Rooms[i]["Players"] do
                        if Rooms[a]["Players"][a] == Player then
                            print("You are already in the room")
                        else
                            RemoteEvent:FireClient(Player, "Success")
                            table.insert(Rooms[a]["Players"], Player)
                        end
                    end
                else
                    RemoteEvent:FireClient(Player, "Success")
                    table.insert(Rooms[i]["Players"], Player)
                end             
            end
        end
    end
end)

现在的问题是，我的代码允许播放器加入两个房间。例如:播放器加入房间[1]，并再次尝试加入房间[1]，它打印：You are already in the room；这是完美的工作！，但问题是，当玩家想要移动到房间时，它不会检查播放器是否已经在另一个房间了。

TL;DR:

• Player加入房间1.
• Output:播放器加入房间1.
• Player加入房间1 again.
• Output:你已经在room.
• Player加入房间2.
• Output (错误)：播放器加入了2.

房间

播放机不应该加入2号房间，因为他们还没有离开1号房间，但是我怎样才能检查玩家是不是在另一个房间呢？

试试这个：

RemoteEvent.OnServerEvent:Connect(function(Player, Key, Data)
    if Key == "Join" then
        local targetRoomNum = nil
        for i, room in pairs(Rooms) do
            if room["UID"] == Data then
                targetRoomNum = i
            end

            for _, playerInRoom in pairs(room["Players"]) do
                if playerInRoom == Player then
                    print("You are already in a room")
                    return
                end
            end
        end
        
        if targetRoomNum then
            RemoteEvent:FireClient(Player, "Success")
            table.insert(Rooms[targetRoomNum]["Players"], Player)
        else
            print("No room found")
        end  
    end
end)
