local find = script.Parent
find.Touched:Connect(function(touched)
local de = find:FindFirstChild("Humanoid")
if de == true then
print("we found a human!")
end
end)
is not working?? I'm new to this but i just don't understand!
The reason why your script is not functioning as intended is because :FindFirstChild() will return an object. (not a boolean)
So your statement is practically stating
local part = Instance.new("Part")
if part == true then -- Part does not equal true
The solution is quite simple. When :FindFirstChild() doesn't find anything it will return nil. So just make sure that it `~=~ nil
local find = script.Parent
find.Touched:Connect(function(touched)
local de = touched.Parent:FindFirstChild("Humanoid")
if de ~= nil then -- checking if a humanoid was found
print("we found a human!")
end
end)
If you are trying to detect if a player was joined then Try use this code:
local find = game:GetService("Players")
find.PlayerAdded:Connect(function ()
print("we found a human")
end)
Copy it into your LocalScript and place your LocalScript in StarterGui library

I wrote a door save system.
That is, if the user previously bought them, then when re-entering the game, they must be open.
My code works, but the door doesn't save at all.
-- DoorsDataStore
-- Save Stats Doors
local opend = false
local datastorage = game:GetService("DataStoreService")
local isitopen_1 = datastorage:GetDataStore("Door")
game.Players.PlayerAdded:Connect(function(player)
local boolValueDoors = Instance.new("Folder")
boolValueDoors.Name = "BoolValueDoors"
boolValueDoors.Parent = player
local door_1 = Instance.new("BoolValue")
door_1.Parent = boolValueDoors
door_1.Name = "BoolValueDoor_1"
door_1.Value = isitopen_1:GetAsync(player.UserId)
print("True or False")
print(player.BoolValueDoor_1.Value)
end)
game.Players.PlayerRemoving:Connect(function(player)
local success, erromsg = pcall(function()
isitopen_1:SetAsync(player.UserId, player.BoolValueDoor_1.Value)
end)
if erromsg then
warn("Error")
end
end)
-- TouchDoor
script.Parent.Touched:Connect(function(hit)
local humanoid = hit.Parent:FindFirstChild("Humanoid")
if (humanoid ~= nil) then
local player = game.Players:GetPlayerFromCharacter(hit.Parent)
if player.leaderstats.Coins.Value >= script.Parent.Price.Value then
player.leaderstats.Coins.Value -= script.Parent.Price.Value
player.leaderstats.Level.Value += 1
script.Parent:Destroy()
player.BoolValueDoors.BoolValueDoor_1.Value = true
print("Save Door")
end
end
end)
I tried writing this code in different ways, in different versions, tried through validation. My code still doesn't do what I want.
There are multiple possible problems I see:
1.
SetAsync takes a string as the first argument, you are giving it a number value. To fix this use tostring(player.UserId)
2.
When the player first joins, the value will be set to nil, because there is no data in the datastore under the UserId, and nil is not a boolean.
I’m not sure if these are actual issues and I currently cannot check if these are real problems because I’m not on my computer but they may be something you want to change.
Also it would be nice to know if you encountered any errors when executing the code.
You should also make trigger a remote event that opens the door on the clientside in the PlayerAdded function if the value is true.
So I decided to make a jump boost gamepass in roblox but when I test and I have my gamepass it doesn't work.
here is my code
local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
local PlayerUserID = Players.LocalPlayer.UserId
print(PlayerUserID)
Players.LocalPlayer.CharacterAdded:Connect(function(char)
print(MarketplaceService:UserOwnsGamePassAsync(PlayerUserID, 21723718))
if MarketplaceService:UserOwnsGamePassAsync(PlayerUserID, 21723718) then
char.Humanoid.UseJumpPower = true
char.Humanoid.JumpPower = 100
end
end)
it is a server script on ServerScriptService
I cant see any output that comes from the script.
You cannot use LocalPlayer in a Server Script. You will have to get the player via other methods.
Check out the Roblox gamepass guide.
Your server script is targeting an object that doesn't exist. game.Players.LocalPlayer is only defined in localscripts.
To get around this, use Players.PlayerAdded
Use this code instead
local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
Players.PlayerAdded:Connect(function(plr)
plr.CharacterAdded:Connect(function(char)
if MarketplaceService:UserOwnsGamePassAsync(PlayerUserID, 21723718) then
char.Humanoid.UseJumpPower = true
char.Humanoid.JumpPower = 100
end
end)
end)
I am having problems with the functionality of a script and I don't know how to solve it.
In the images below attach photos of the in-game problem, this means that the whole script works and in-game the property of the visible "bframe" is false but in-game this is not shown and I want to know how I can solve it ..
in-game mode the visibility of the "Bframe" it becomes false in the property (that's fine) but in-game this is not seen..
Does anyone know how to solve it?
Button script
-- Events
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Evento = ReplicatedStorage.RemoteEvent
-- end of Events
local button = script.Parent
local frame = script.Parent.Parent.Parent.Frame
Evento.OnClientEvent:Connect(function(argumento1)
button.MouseButton1Click:Connect(function()
if frame.Visible == false then
frame.Visible = true
button.Visible = false
else
frame.Visible = false
end
end)
end)
Server script
-- Events
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Evento = ReplicatedStorage.RemoteEvent
-- end of Events
game.Players.PlayerAdded:Connect(function(player)
Evento:FireClient(player,"argumento1")
print("testing probado")
end)
Redteam / touch part script called script
local wll = script.Parent.Part
local fr = game.StarterGui.TeamChangerGui.BFrame
local function Toch()
fr.Visible = false
fr.button.Visible = false
print("visible desactivado")
end
wll.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild("Humanoid") then
Toch()
end
end)

Is the button script a localscript? if it is then it may be to do with the fireclient although I am not good at it and I usually use fireallclients passing through the player name then checking if its the correct name on the clients side script.
Otherwise I am not sure as it is an interesting issue i have never encountered. Hope it works!
I made a cash for kill script in Roblox, but wanted to go further than that and implement a script where when a player has a gamepass, then that player would recieve more cash than another normal player would.
This is for a battle royale styled game in Roblox, and when I playtested it, there were no errors, but the script didn't work.
game.Players.PlayerAdded:connect(function(player)
local folder = Instance.new("Folder",player)
folder.Name = "leaderstats"
local currency1 = Instance.new("IntValue",folder)
currency1.Name = "Cash"
local increment = 50
if game:GetService("MarketplaceService"):PlayerOwnsAsset(player,7382818)then
increment = increment + 50
end
player:WaitForChild("Humanoid").Died:connect(function()
local tag = player.Humanoid:FindFirstChild("creator")
if tag ~= nil then
local killer = tag.Value
if killer ~= nil then
-- Find the killer's leaderstats folder
local killerStats = killer:FindFirstChild("leaderstats")
if killerStats ~= nil then
-- Find the killer's Cash IntValue
local killerCash = killerStats:FindFirstChild("Cash")
-- Increase cash as before
killerCash.Value = killerCash.Value + increment
end
end
end
end)
I expected a VIP player, who has the gamepass, to receive more cash, but when I tested it, no player received any cash for killing another player at all.
How to fix an end expected error near eof
If the Lua interpreter complains about a missing end you`re missing it somewhere.
Read through your code and make sure everything that is supposed to be closed with an end has one. Read through the Lua Reference Manual to find out which keywords need an end.
In your code it's if statements and function definitions. Checking each pair from inside out you'll end up one end) short to close this game.Players.PlayerAdded:connect(function(player) as mentioned in the comments.
I am making a Roblox game, and I need to detect a player's team somehow.
My code currently looks like this:
script.Parent.Touched:Connect(function(part)
local plr = part.Parent.Name
if (game.Players:FindFirstChild(plr).Team == "Police") then
....
end
end)
And when I touch that part (it's an invisible wall), it gives me an error: Workspace.Part.Script:3: attempt to index a nil value
What am I doing wrong?
Edit: I found out it can't find my name in game.Players, because now I tried:
script.Parent.Touched:Connect(function(hit)
local plr = game.Players:FindFirstChild(hit.Parent.Name)
if (plr.Team == "Police") then
...
And now I get Workspace.Part.Script:3: attempt to index local 'plr' (a nil value)
Edit2: Now I tried printing plr (game.Player:FindFirstChild(hit.Parent.Name)) and it was ' Miniller', not 'Miniller', and now I didn't get any errors, but the code below also did nothing..
I solved it by not using variables AND not "Police", it's game.Teams.Police, so code:
if (game.Players:FindFirstChild(hit.Parent.Name).Team = game.Teams.Police
...
