local Room = {}
Room.random = Random.new()
function Room.generate(prevRoom)
local possibleRooms = workspace.Rooms:GetChildren()
local randomRoom = possibleRooms[Room.random:NextInteger(1, #possibleRooms)]
local newRoom = randomRoom:Clone()
newRoom.PrimaryPart = newRoom.Entrance
newRoom:PivotTo(prevRoom.Exit.CFrame)
newRoom.Entrance.Transparency = 1
newRoom.Exit.Transparency = 1
newRoom.Parent = workspace.GeneratedRooms
return newRoom
end
return Room
This is my code for the ModuleScript, and here is the ServerScript:
local room = require(script.Room)
local prevRoom = workspace.StartRoom
for i = 1, 10 do
prevRoom = room.generate(prevRoom)
end
So I'm running my program and it says my model (LongRoomRoof) has not got a valid part of my other model (Entrance) and then it points me to line 9 of the above script (Module for localRoom.) Please does anyone know how to fix this issue. I'll paste the error here:
Entrance is not a valid member of Model "LongRoomRoof" - Server - Room:9
If you can please tell me how fixing this is possible Thanks!

I need to make a trolleybus number, which won't repeat for game. For example, there is a number "101" and there musn't be more "101". How to do that? I have a code, but I know, he won't work and I won't test it lol
function giveNumber()
local number = math.random(100, 199)
local takedNumbers = {}
local i = 0
local massiv = i+1
script.Parent.pered.SurfaceGui.TextLabel.Text = number
script.Parent.zad.SurfaceGui.TextLabel.Text = number
script.Parent.levo.SurfaceGui.TextLabel.Text = number
script.Parent.pravo.SurfaceGui.TextLabel.Text = number
takedNumbers[massiv] = {number}
end
script.Parent.Script:giveNumber() // what I wrote here? idk...
if number == takedNumbers[massiv] then
giveNumber()
end
i didn't test it, because I think it won't work because this code is something bad
I think this will serve your needs.
In the function generateUniqueNumber, the script loops until it found a number that is not yet in the array. (in other words, that it hasn't given out yet)
Once it found that number, it will insert it into the table to remember that it has given it out, and then it will return the number.
Then on the bottom of the script we just give the numbers to the buses :-)
--[[
Goal: Give all buses a unique number
]]
-- Variables
local takenNumbers = {};
-- This function returns a random number in the range [100, 199] that has not been taken yet
function generateUniqueNumber()
local foundNumber = false;
while not foundNumber do
randomNumber = math.random(100, 199);
if not table.find(takenNumbers, randomNumber) then
table.insert(takenNumbers, randomNumber);
return randomNumber;
end
end
end
-- This function sets the number of the bus
script.Parent.pered.SurfaceGui.TextLabel.Text = tostring(generateUniqueNumber());
script.Parent.zad.SurfaceGui.TextLabel.Text = tostring(generateUniqueNumber());
script.Parent.levo.SurfaceGui.TextLabel.Text = tostring(generateUniqueNumber());
script.Parent.pravo.SurfaceGui.TextLabel.Text = tostring(generateUniqueNumber());

I didn't test this code as Roblox is not installed on the pc I'm currently on.
Please try formatting your code nicely next time. It greatly improves the readability! For example, you can use this website:

Fill a table with free numbers...
local freenumbers = {}
for i = 1, 99 do freenumbers[i] = i + 100 end
...for every new takennumbers use table.remove() on freenumbers
local takennumbers = {}
if #freenumbers > 0 then
takennumbers[#takennumbers + 1] = table.remove(freenumbers, math.random(1, #freenumbers))
end
i have this scripts error below:
attempt to call a boolean value
attempt to call a number value
Here is the script :
--Game Info
local SystemName = "TestSystemname"
local WhitelistedServ = false
local OwnerId = game.CreatorId
local GameId = game.GameId
local MaxPlayers = game.Players.MaxPlayers
local GameUrl = "https://www.roblox.com/games/"..GameId
--Webhook sender and message creator in JS
local WebhookUrlServ = ""
local MessageDataServ = {["content"] = "New game started with the whitelist system !"..SystemName
"The Owner Id= "..OwnerId
"Is Game whitelisted ? "..WhitelistedServ
"How Many Players Max? "..MaxPlayers
"The Game Url= "..GameUrl}
MessageDataServ = HttpServ:JSONEncode(MessageDataServ)
Thanks,
I found the problem, i tryed to send a value i just need replace this
local WhitelistedServ = false
by this
local WhitelistedServ = "false"
and it will be work, value cant be in this script for some reason and make with embed is better.
I’m trying to create a table that is dynamically populated with the on/off status of set of switches I have. The following is where I I’ve got stuck as it always returns nothing/nil? ..
-- retrieved http.request status of 4 binary switches
local P61v = 1
local P62v = 0
local P63v = 1
local P64v = 0
— following table should allow us to look up the status of all associated light by their plug names P61, P62, P63 etc.
local LookupTable = {
P61 = P61v,
P62 = P62v,
P63 = P63v,
P64 = P64v
}
local x = LookupTable[P62]
print(x)
In LookupTable[P62] the expression P62 is evaluated to nil, resulting in LookupTable[nil] which resolves to nil.
What you are looking for is either
LookupTable.P62
-- or --
LookupTable['P62']
which are equivalent ways of expressing the same thing.
I created a script that defines both values, and this is what I ended up with..
local PowerResponse = "P61=0,P62=1,P63=0,P64=0"
local P61, _, P61v, P62, _, P62v, P63, _, P63v, P64, _, P64v = PowerResponse:match("(%w*)(=)(%d),(%w*)(=)(%d),(%w*)(=)(%d),(%w*)(=)(%d)")
local PowerStatusTable = {
P61 = P61v,
P62 = P62v,
P63 = P63v,
P64 = P64v
}
--local x = PowerStatusTable[P62]
for k, v in pairs(PowerStatusTable) do
luup.variable_set("urn:upnp-net:serviceId:IPPower1", k, v,deviceID)
end
I get an error that says in line 3, '=' expected near 'local'.
I'm trying this : local = fireball = game.ServerStorage.Fireball.
I typed the equal sign where I thought it needs to go, but it doesn't work...
This is the code :
local cannon = script.Parent
local barrel = script Workspace.cannontrap.TrapBarrel
local = fireball = game.ServerStorage.Fireball
while true do
local fireballCopy = fireball:Clone()
fireballCopy.Parent = game.Workspace
fireballCopy.Position = barrel.Position
fireballCopy.Velocity = Vector3.new(-80,0,0)
wait(8)
end
(Line 3 is incorrect for this error).
The error message is clear. This line
local = fireball = game.ServerStorage.Fireball
should be
local fireball = game.ServerStorage.Fireball
There shouldn't be a "=" after the local it should be
local fireball = game.ServerStorage.Fireball
Hope this helps!
Right now I'm trying to use Lua to receive variables from barcodes sent out from an outside source. When I run this, there is a variable rotation from the local function rot(input) that appears to be "buggy". If I run this code exactly as it is with the print statements below, the rotation will appear and disappear. Please help me understand why this may happen?
Please note: There are two aspects of this code that I'm currently working on. A) Code128 is not properly retrieving the variables. B)My code can definitely be shortened. But I'm new and learning as I go. The main purpose for this thread is to help me understand why code will sometimes display the desired result, then won't the next minute?
Thank you.
Edited: I've updated the code a bit to make it cleaner. Condensed all of my string.match statements into tables with other barcode related fields. Still learning and looking to make it even more cleaner. I love learning this, but am still having the same problem with my local function rot(input) and getting intermittent results. Any help is greatly appreciated!
local function rot(input)
rotTable = {["R"] = "cw", ["I"] = "180", ["B"] = "ccw"}
for k,v in pairs (rotTable) do
if input == k then
rotation = v
else
rotation = ""
end
end
return rotation
end
local function barCode(input)
local bcID = string.match(input,"%^(B%w)")
if bcID == "BY" then
bcID = string.match(input,"%^BY.*%^(B%w)")
end
local bcTable = {
["BC"] = {"code128", 10, string.match(input,"%^BY.*%^BC(%u),(%d*),(%u),%u,%u%^FD(.*)%^FS")},
["B2"] = {"bc2of5i", 20, string.match(input,"%^B2(%u),(%d*),(%u),%u,%u%^FD(.*)%^FS")},
["BE"] = {"ean13", 10, string.match(input,"%^BE(%u),(%d*),(%u),%u%^FD(.*)%^FS")},
["B8"] = {"ean8", 10, string.match(input,"%^B8(%u),(%d*),(%u),%u%^FD(.*)%^FS")},
["B3"] = {"code39", 10, string.match(input,"%^B3(%u),%u,(%d*),(%u),%u%^FD(.*)%^FS")},
["BU"] = {"upc_a", -1, string.match(input,"%^BU(%u),(%d*),(%u),%u%,%u^FD(.*)%^FS")}
}
for k,v in pairs (bcTable) do
if bcID == k then
bcFields = v
bcType, qzone, bcR, bcH, bcHr, bcData = unpack(bcFields)
end
end
hPos = 0
vPos = 0
bcOutput = '<'..bcType..' qzone=\"'..qzone..'\" hbb=\"0\" vbb=\"0\" bbwidth=\"1\" hpos=\"'..hPos..'\" vpos=\"'..vPos..'\" rotation = \"'..rot(bcR)..'\" bgcolor=\"0\" barcolor=\"255\" textcolor=\"255\" barwidth=\"1\" height=\"8\">'..bcData..'</'..bcType..'>'
return bcOutput
end
print(barCode("^BY3^BCN,102,N,N^FDCHF05000042^FS"))
print(barCode("^B2B,110,N,N,N^FD45681382^FS"))
print(barCode("^BUN,183,N,N,N^FD61414199999^FS"))
print(barCode("^B8I,146,N,N^FD212345645121^FS"))
print(barCode("^BEB,183,N,N^FD211234567891^FS"))
I'm not sure what is wrong with your code, if anything, but rot can be written more simply as
local rotTable = {["R"] = "cw", ["I"] = "180", ["B"] = "ccw"}
local function rot(input)
return rotTable[input] or ""
end
In general, you shouldn't need to search Lua tables. For instance, the loop for k,v in pairs (bcTable) do can be replace by indexing as in the code above.
