Roblox Lua - attempt to index nil with 'stats' (leaderstats) - lua

i want to make this, when the baseFinal is touched by a block (Bloque) it gives you money and the block is destroyed. it gives me an error: attempt to index nil with 'stats'
local base = script.Parent.Base
local baseFinal = script.Parent.Final
local plr = game.Players.LocalPlayer
baseFinal.Touched:Connect(function(hit)
if hit.Name == "Bloque" then
wait(0.6)
plr.stats.Value = plr.stats.Value + 5 // here is the error
hit:Destroy()
end
end)

The error is telling you that the plr variable is undefined or nil.
Since this code is running in a Script, the issue is how you are accessing the Player object. See the documentation for Players.LocalPlayer :
This property is only defined for LocalScripts (and ModuleScripts required by them), as they run on the client. For the server (on which Script objects run their code), this property is nil.
The way to fix this is to access the Player object another way. One way is to connect to the Players.PlayerAdded signal.
local base = script.Parent.Base
local baseFinal = script.Parent.Final
local connections = {}
game.Players.PlayerAdded:Connect( function(plr)
-- listen for Players to touch the block
local connection = baseFinal.Touched:Connect( function(hit)
if hit.Name == "Bloque" then
wait(0.6)
plr.stats.Money.Value = plr.stats.Money.Value + 5
hit:Destroy()
end
end)
-- hold onto the connection to clean it up later
connections[plr] = connection
end)
-- clean up when the Player leaves
game.Players.PlayerRemoving:Connect( function(plr)
connections[plr]:Disconnect()
end)

This is most likely because when you are trying to reference a value, you must put .Value after it in order to change the value itself. Assuming you have a stats folder, you should use plr.stats.Value.Value instead.
Next time, please show us your object structure so we have a better understanding of what the error is. Thanks.

attempt to index nil with 'Character' Error Roblox Studio

Hello i am trying to get the position of the HumanoidRootPart but it says attempt to index nil with 'Character' also the FollowPlrbox has the players name.(This not a local script)
Script:
script.Parent.MouseButton1Click:Connect(function()
local fwbox = script.Parent.Parent.FollowPlrbox.Text
local player = game.Workspace:FindFirstChild(fwbox)
local plrpart = player.Character:FindFirstChild("HumanoidRootPart")
local plrposx = plrpart.Position.X
print(plrposx)
end)
Error:
attempt to index nil with 'Character'
Your error is telling you that player doesn't exist. This could mean that whatever you have typed for the player's name is misspelled, incorrect capitalization, or there's simply no player with that name.
Anyways, you need to account for the fact that the player might not exist before trying to access properties on it. Also, since you are searching the Workspace, you are not looking for a Player, you are looking for that player's character model.
So to fix your issue, you simply need to add safety checks.
script.Parent.MouseButton1Click:Connect(function()
local fwbox = script.Parent.Parent.FollowPlrbox.Text
local character = game.Workspace:FindFirstChild(fwbox)
if character then
local rootPart = character:FindFirstChild("HumanoidRootPart")
if rootPart then
local rootPartPosX = rootPart.Position
print(rootPartPosX)
end
end
end)
The reason we add if character then and if rootPart then is because it's possible that the FindFirstChild() function won't find anything. So we say, only do the rest of this code if character exists.

Roblox Lua: Issue defining a value in a player's leaderstats folder (no error message)

I have a system in my game where when a player steps on a checkpoint, a Stage value in the leaderboard will go up, and then that value is saved to that player's userId.
I want there to be a button that resets that value back to 0, and this is the code I tried for it.
local textButton = script.Parent
local Players = game:GetService("Players")
textButton.MouseButton1Up:Connect(function()
local player = game.Players.LocalPlayer
local stage = Players:WaitForChild(player):WaitForChild("leaderstats").Stage
if stage.Value > 1 then
stage.Value = 1
end
end)
I've tried debugging it by putting print commands in different places to see where the code gets, and when I try to run print(stage) it does not show anything.
LocalScripts cannot change the value on the server. To change a value once a button is clicked, RemoteEvents should be used.
There is a page documenting about them here: https://create.roblox.com/docs/scripting/networking/remote-events-and-functions
To use a RemoteEvent, first you need to put it in a place that is replicated across the server and the client. A good example of this would be to put it in ReplicatedStorage. After that, you need to set up a script that listens for the .OnServerEvent event of the RemoteEvent. To do this, you need to connect a function. As seen in your script, you already know how to do this. So I will get straight to the point.
On the server, set up a script that listens for .OnServerEvent. Next, on the client, edit your script to fire the client instead of trying to set the value. Go back to the server script, and set the value there. The event also passes the Player object, so you can utilize that to actually reset the value.
TLDR;
LocalScript inside of your TextButton:
local textButton = script.Parent
local Players = game:GetService("Players")
local RemoteEvent = 'RemoteEvent location'
textButton.MouseButton1Up:Connect(function()
RemoteEvent:FireServer()
end)
Server Script in anywhere, preferably ServerScriptService:
RemoteEvent.OnServerEvent:Connect(function(player)
local Players = game:GetService("Players")
local stage = Players:WaitForChild(player):WaitForChild("leaderstats").Stage
if stage.Value > 1 then
stage.Value = 1
end
end)
Good luck!

What does "attempt to index function with 'Connect'" mean in Roblox?

local Player = game.Players.LocalPlayer
local PlayerCash = Player:WaitForChild("leaderstats"):WaitForChild("Strength")
local Mouse = Player:GetMouse()
local amount = 50
script.Parent.Activate:Connect(function()
game.Players.LocalPlayer.leaderstats.money.Value = game.Players.LocalPlayer.leaderstats.money.Value + amount
end)
I am trying to make a code to give Strength when you click. When I press 'Play' it doesn't work. All it says in the output is
'attempt to index function with 'Connect'.'
The error "attempt to index [type] with [field name]" means that you are incorrectly using something like an object, and you are trying to access some field on it.
In your case, this error is pointing at the line : script.Parent.Activate:Connect.This says that script.Parent.Activate is a function and not a table, and you cannot call Connect on a function. This is just to help us figure out what is wrong with our code.
Since you working with Tools, there is a simple fix. Instead of using the Activate function, you are looking for the Activated event. So just change update that line like this :
script.Parent.Activated:Connect(function()
It connects a function to an event that happened, like this:
local tool = script.Parent
-- It connects the event (the tool being equipped) to a function.
tool.Equipped:Connect(function()
-- CODE
end)
Also, the answer above is how you can fix your problem and here's a shortcut: You have defined "Player" and you could've used it inside the function. Have a great day and God bless everyone here.

attempt to index nil with 'leaderstats' in roblox studio

local garbage = game.Teams["Glizzy Garbage"]
local player = game.Players.LocalPlayer
if player.leaderstats.Pounds.Value <= 1000 then --this is the line that the output is detecting the error
player.Team = garbage
end
I am trying to make it where when the player reaches a certain amount of 'pounds' then they will automatically receive a roll. I've searched through many youtube videos and haven't found a fix or an alternative way to do this, and I'm not sure why this isn't working. This script is located in the workspace. All help is appreciated.
The LocalPlayer object is only exposed in LocalScripts. Because you're using a Script in the Workspace, you'll have to access the player object another way. It's also a good idea to handle this kind of logic inside a function that is fired any time the Pounds value changes.
Try using the game.Players.PlayerAdded signal :
local garbage = game.Teams["Glizzy Garbage"]
game.Players.PlayerAdded:Connect(function(player)
local Pounds = player.leaderstats.Pounds
Pounds.Changed:Connect(function(value)
if value <= 1000 then
player.Team = garbage
end
end)
end)
Mine is just
local plrStage = plr.leaderstats.Stage.Value
try instead of putting team name put team colour
also use
player.Team.Service = garbage
end)

Bailing people out of prison in roblox using Remote Events doesn't seem to work properly

Here's the deal. When you get arrested in my game, you get sent to jail. To get out you must be bailed out.
The client sends a request to the server to bail them. Every other part seems to work except this part I believe, however it could be the client side script. Is there anything incorrect about this script? I have checked it for any errors that are obvious to me.
local replicatedStorage = game:GetService('ReplicatedStorage')
local createSystemMessage = replicatedStorage:WaitForChild('CreateSystemMessage')
game.ReplicatedStorage.Bail.OnServerEvent:Connect(function(Player,PlayerToBail)
Player = game.Players:FindFirstChild(Player)
local tab = nil
for i,v in pairs(_G.GlobalData) do
if v.Name == Player.Name then
tab = v
end
end
if PlayerToBail.Team == game.Teams:FindFirstChild("Criminal") then
local Bounty = PlayerToBail.leaderstats.Bounty.Value * 2
if tab.Bank <= Bounty then
tab.Bank -= Bounty
PlayerToBail.leaderstats.Bounty.Value = 0
PlayerToBail.Prisoner.Value = false
PlayerToBail.Team = game.Teams:FindFirstChild("Civilian")
createSystemMessage:FireAllClients((Player.Name .. ' has Bailed ' .. PlayerToBail.Name), Color3.fromRGB(0, 250, 0))
end
end
end)
And the local script which works:
script.Parent.AcceptButton.MouseButton1Click:Connect(function()
local PlayerName = script.Parent.TargetName.Text
game.ReplicatedStorage.Bail:FireServer(PlayerName)
print ("Bail Requested")
end)
I believe the problem occurs with the argument you're passing to the remote event.
In your client script you pass PlayerName as an argument. I'm assuming this is a string of the player's name:
game.ReplicatedStorage.Bail:FireServer(PlayerName)
PlayerName will actually be sent to the parameter "PlayerToBail", which I'm assuming is supposed to be a player object. Keep in mind that Roblox's RemoteEvents automatically pass in the player who fired the remote event as the first argument. So the "Player" parameter of the function connected to your remote event is the actual player object that has the local script that fired the remote event.
Instead, I would fire the remote event like this:
game.ReplicatedStorage.Bail:FireServer()
Since the player you want to bail is automatically passed as an argument, you don't need to add any additional arguments to FireServer. In addition, you would get rid of the "PlayerToBail" parameter in your server script.
Also note, it is unnecessary to have this line of code in your server script:
Player = game.Players:FindFirstChild(Player)
Player is already referring to an object in game.Players. In addition, Player is an object, not a string. So this would not work. You can simply use Player as is for your purposes.
More info on Remote Events: https://developer.roblox.com/en-us/articles/Remote-Functions-and-Events
Please feel free to follow up if you still have issues.
When firing the server it automatically gives a parameter which is the player who sent it. So, you don't have to have the playerName part because after the player parameter is already there and you can get the name from that.
