You can write your topic however you want, but you need to answer these questions:
-
What do you want to achieve? Keep it simple and clear!
-
What is the issue? Include screenshots / videos if possible!
-
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!

Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.
I should preface this by stating that I have been away from ROBLOX developing for a good 3 years, and have left my one truly scripted-by-me game unfinished. With that said, I’m looking at it again and trying to untangle all of the spaghetti code that I put into it (I should also mention I have not been coding at all during this time). The game is a kind of turn-based game where everyone is on a grid of tiles and they all select a tile to jump to every few seconds, and different tiles have different power-ups, effects, attacks, etc. As you might already be able to tell there’s a lot of interconnectedness going on here and tracking down the source of bugs has become challenging fast. Long story short the very first tile effect I wanted to work on was a teleport tile where when you landed on it it would randomly teleport you to a different tile on the grid. Simple enough, right? Well, let me just paste the code and the output now and see if anybody can help me make heads or tails of this.
local bindable = game:GetService("ReplicatedStorage"):WaitForChild("bindable")
local Players = game:GetService("Players"):GetPlayers()
local playersPlayer
bindable.Event:Connect(function(player, tileToBeFired, Row)
print('Teleport function fired!')
if tileToBeFired == script.Parent.Name and tostring(Row) == script.Parent.Parent.Name then
print("Teleportation sequence has started...")
for i,v in pairs(Players) do
print("Searching through available teleportation subjects...")
if v.Name == player.Name then
print("Eligible subject found...")
playersPlayer = v
return playersPlayer
end
end
end
print(playersPlayer.Name)
playersPlayer.ClickRowString.Value = "ClickRow"..math.Random(1,5)
print(playersPlayer.ClickRowString.Value)
local rightHalf = (math.Random(1,2))
if rightHalf == 1 then
playersPlayer.ClickTileString.Value = "ClickTile00"..math.Random(1,9)
else
playersPlayer.ClickTileString.Value = "ClickTile0"..math.Random(10,15)
end
for i,v in pairs(game.Workspace.TileGrid.ClickRows:GetChildren()) do
if v.Name == playersPlayer.ClickRowString.value then
for x,z in pairs(v:GetChildren()) do
if z.Name == playersPlayer.ClickTileString.Value then
playersPlayer.Character.cPart.Position = z.Position + Vector3.new(0, 3.5, 0)
end
end
end
end
print("Player "..player.Name.." has telported!")
end)

OK a couple things about this output. It start’s with the print “Jumped!” which is a successful initiation of the script that carries the player from one tile to another. I land on the teleport tile, which you can see “Teleport function fired” then after a few prints because I was seeing if the issue was that it couldn’t find anybody to teleport, it once again says “Teleport function fired”. This is the first major issue I think may be going on, something is causing it to fire off multiple times and it’s possibly breaking as a result, maybe. Then after that, I get the error “Workspace.TileGrid.PeakRow2.Tile7.Script:22: attempt to index nil with ‘Name’ - Server - Script:22” referring to the line “print(playersPlayer.Name)”. This contradicts the print before it that said “Eligible subject found” which would mean that it successfully found my name and returned my player into the variable playersPlayer (pls don’t judge my variable naming from three years ago). Now, move past a bunch of prints and output and what-not and it gets to the second jump, with the print “Jumped!” immediately followed by “Orange!” (I think orange is referring to the color of tile? Not completely sure). After this, it prints my name, GuruNin, from the same script that called an error on it a moment ago. This is a problem for two reasons, one is that it should have successfully printed my name the FIRST time it ran, and second is that it shouldn’t have been fired at all this second time, because the teleport tile is supposed to run when you jump to it, not away from it. After this, I get the error “Workspace.TileGrid.PeakRow2.Tile7.Script:23: attempt to call a nil value - Server - Script:23”, referring to the line “playersPlayer.ClickRowString.Value = “ClickRow”…math.Random(1,5)”. The ClickRowString is a string that I automatically insert all of the players at the start of the game, and the scripts use it to determine which tile in the grid they’re going to jump to next. I have no idea why it calls this a nil value, unless playersPlayer is returning nil, which it isn’t, because it just printed my name when I put in print(playersPlayer.name) in the line above.
And you’ll notice that the teleport function fires AGAIN after this, and returns the same error. Firing 3 times for the price of one.
And also notice that it doesn’t print all of the “Teleportation subject found” stuff each time it fires, and it doesn’t attempt to print my name each time it fires, it’s like it’s selectively firing part of my script and not the other. I know that shouldn’t be possible, but here we are.
And since I haven’t mentioned it and it’s probably important, let me grab the script that actually calls this one to be fired…
local function fireTile()
for i,v in pairs(plrs) do
for x,z in pairs(rows) do
if v.ClickRowString.Value == "ClickRow"..x then
local Row = z
for y,w in pairs(z:GetChildren()) do
if v.ClickTileString.Value == "ClickTile00"..y then
tileToBeFired = "Tile"..y
player = v
bindableFire:Fire(player, tileToBeFired, Row)
elseif v.ClickTileString.Value == "ClickTile0"..y then
tileToBeFired = "Tile"..y
player = v
bindableFire:Fire(player, tileToBeFired, Row)
end
end
end
end
end
end
while true do
wait(1)
for i,v in pairs(plrs) do
fireClientCreateClickDetectors(v)
end
wait(3)
for i,v in pairs(plrs) do
fireClientDestroyClickDetectors(v)
end
movePlayers()
updateRows()
wait(1)
fireTile()
wait(3)
end
It’s a lot of hubbub I know but the jist of it is that it’s locating the row and column that the player is currently located at and I think it’s running the script inside of that tile only? Somehow it’s firing that tile and not any other tile I forget how that works exactly but yeah. Then after that I just showed the sequence of functions that causes the game to run, it has a lot of functions that I didn’t show but they shouldn’t be relevant to this particular problem and it just shows the flow of how the game runs hopefully, it’s a real simple game despite all of the pain-in-the-butt scripting that goes into it haha. If anybody is nice enough to read this far and actually try and help I ask that you kind of explain stuff to me in a real basic way, like I said I haven’t touched coding in 3 years, but this is a passion project of mine because it’s based on a game that I played when I was younger that’s no longer available on the internet, so I’m not ready to give up on it yet. Thanks in advance, peace.
