I'm trying to test out a game that gives coins to the player(via leaderstats) when you touch this block. When I touch the block though, my leaderstats don't change and I don't get any errors. Heres my Script
enter image description here
game.Players is a service and is not the Player who owns the Character that touched TestPart. The Players service provides a method to get the Player from a Character called GetPlayerFromCharacter(character).
TestPart.Touched:Connect(function(hit)
local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
if plr then
plr.leaderstats.Coins.Value += 1
end
end)
Luau supports increments (+=) but not lua.

I am on Roblox again, and I wanna make a script where when a part is touched, if the player name is lorenzoomh, set the brickcolor to green. But if not, set it to red. my current code:
script.Parent.Touched:Connect(function(igottouched)
if game.Players.LocalPlayer.Name == "lorenzoomh" then
script.Parent.BrickColor = BrickColor.Green()
else
script.Parent.BrickColor = BrickColor.Red()
end
end)
which doesnt work btw
The answer to your question, "can I use a player's name in an if-statement" is yes. Your problem is that the LocalPlayer doesn't exist where you're trying to use it from.
See the docs for Players.LocalPlayer :
This property is only defined for LocalScripts ... as they run on the client. For the server (on which Script objects run their code), this property is nil.
You need to access the Player object a different way. The Touched event on a Part gives you access to the other object that touched it. You can use that to check if the other part belongs to a player's character model.
local target = game.Workspace.Part
-- listen for a player touching a block
target.Touched:Connect( function(otherPart)
-- check that the thing that touched is a character model
local character = otherPart.Parent
local isCharacter = character:FindFirstChild("Humanoid") ~= null
if isCharacter then
-- the character model name is usually the name of the player so use that
if character.Name == "lorenzoomh" then
target.BrickColor = BrickColor.Green()
else
target.BrickColor = BrickColor.Red()
end
end
end)
The Players service has a method for correlating a character model with a Player object specifically if a simple name check is not sufficient for your use case.
I want to make a Roblox game with multiple scenes that you can load your character into.
The problem with this is that I cannot find any way to do this. I’ve done a reasonable amount of research online, but all I get are guides on how to load a character once using a plugin, rather than getting the person who joined’s character and loading it into a certain position.
How to get the person who joined’s character and load it into a certain position?
To create somebody's character, call Players:CreateHumanoidModelFromUserId with the Player's UserId. Then you can move it by calling PivotTo on their HumanoidRootPart.
Note: do not use Model.PrimaryPart to grab the HumanoidRootPart. On R6 characters, this is actually the character's Head. You're better off calling FindFirstChild("HumanoidRootPart") (or WaitForChild).
You'll notice that this positions the character from their torso's center, and not from their feet. So you'll need to offset that vertically by 3 studs if the character is not Rthro (is of fixed size, like R6). If the character is Rthro (is R15, and your game has scaling enabled), then you'll need to call GetExtentsSize on the character Model.
So, something like:
local Workspace = game:GetService("Workspace")
local Players = game:GetService("Players")
local function loadStage(player: Player)
-- ...
local character = Players:CreateHumanoidModelFromUserId(player.UserId)
local rootPart = character:FindFirstChild("HumanoidRootPart")
-- assuming R6 this will be fine
rootPart:PivotTo(CFrame.new(myDesiredPosition + Vector3.yAxis * 3))
rootPart.Parent = Workspace
-- ...
end
Players.PlayerAdded:Connect(function(player)
loadStage(player)
end)
I use MoveTo for following the position and change the CFrame for rotation but it looks supper jaggy. I think the problem is that the code is on the server-side and not on the client-side since I want other players to be able to see the object following the player
Try using weldConstrain. You can create it by code and connect 2 parts to it. The parts are going to stay at the same relative position from each other. Here is a link for the API reference about the subject: https://developer.roblox.com/en-us/api-reference/class/WeldConstraint
Here is an example code that adds a part at the top of a player's head when it joins the game:
local Players = game:GetService('Players') -- get's the players service
local function OnPlayerAdded(player)
local PlayerCharacter = player.Character
-- waits until the player's character loads
while PlayerCharacter == nil do
wait(1)
PlayerCharacter = player.Character
end
-- Get's the player's model in workspace
local PlayerModel = workspace:WaitForChild(PlayerCharacter.Name)
-- Get's the player's head inside it's model
local PlayerHead = PlayerModel:WaitForChild('Head')
-- Write the path to the part you want to follow the player, bellow
local FollowPartOriginal = workspace:WaitForChild('Part')
-- If you want to clone the part, so more players can be followed by it,
-- don't delete the line below, if you want only 1 part, delete the line below.
local FollowPart = FollowPartOriginal:Clone()
-- set's the part position on top of the player's head, with an offset
FollowPart.Position = PlayerHead.CFrame.p + Vector3.new(0,2,0)
FollowPart.Parent = workspace
-- creates a weldconstrain
local WeldConstraint = Instance.new('WeldConstraint')
-- connect's the weld to the player's head and the other part
WeldConstraint.Part0 = PlayerHead
WeldConstraint.Part1 = FollowPart
WeldConstraint.Parent = PlayerHead
end
Players.PlayerAdded:Connect(OnPlayerAdded)
Place this code in a script(not a local script).
If you use the function separately, don't forget to put the player parameter. The parameter needs to contain the player Instance(ex: game.Players.PlayerName)
To change the part position, use the offset in this line of the code:
FollowPart.Position = PlayerHead.CFrame.p + Vector3.new(write offset here)
If you want the part the stop following the player, make a script to delete the part, or the weld constrain(child of the player's head)
When trying to create a code, that on FireServer with Specific Player chosen a GUI would've been cloned into their PlayerGui, But instead I get a nil value.
Code:
local Blinder = game.ReplicatedStorage.RCD.Blind
Blinder.OnServerEvent:Connect(function(player, PlayerToBlind)
if not player:IsInGroup(7465879) then return false end;
script.BL:Clone().Parent = PlayerToBlind:WaitForChild("PlayerGui")
print("Done")
end)
Basically what I try to reach is if my Admin Panel Remoteevent is fired, and a Target has been chosen, the Targeted Player will become a Cloned GUI into their PlayerGui
Any fix on this error?
The error message itself is telling you that you are calling a function that doesn't exist. This issue is caused by an object not being the type you expect.
Unfortunately, the message is pointing at a line that has a few function calls, so it's difficult to say what is causing the exact error. Either script.BL isn't an object with a Clone() function, or PlayerToBlind isn't an object with a WaitForChild() function.
If you can break the operations into a few different lines and add safety checks along the way, you can guarantee that your code is safe and being called properly.
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local Blinder = ReplicatedStorage.RCD.Blind
local BL = script.BL
Blinder.OnServerEvent:Connect(function(player, PlayerToBlind)
-- check that the person calling Blinder:FireServer actually provided a PlayerToBlind
assert(type(PlayerToBind) == "string", "Blinder expects PlayerToBind to be the name of a player")
-- escape if the player is not in the appropriate group
if not player:IsInGroup(7465879) then
return
end
-- find the Player object based on the name provided from PlayerToBlind
local blindedPlayer = Players:FindFirstChild(PlayerToBlind)
if not blindedPlayer then
warn("Could not find player named : ", PlayerToBlind)
return
end
-- create a blinding UI on the other player
local targetGui = blindedPlayer:WaitForChild("PlayerGui")
local newBL = BL:Clone()
newBL.Parent = targetGui
print("Done")
end)
By adding asserts into your code, it won't stop your code from breaking, in fact it will force your code to break faster and in expected ways.
The issue has been fixed,
I have been setting up the LocalScript wrong.
(I grabbed the Text from a TextButton, Instead of the TextBox)
How do I make a script if somebody touched a brick and then maybe a GUI then shows subtitles for like a few seconds and goes the downside of your screen? (like credits after a movie)
I know the first part of creating this but I do not know the GUI part. For the first part, I think you should do something like this...
local Part = script.Parent -- This would define the part that is to be touched.
function onTouch(Brick) -- Starts the onTouch function which sends us "Brick", the triggering object.
local Player = Brick.Parent:findFirstChild("Humanoid") -- Finds Humanoid in Brick.
if (Player ~= nil) then -- Checks if the player is a real Player.
print("Hello World"")
end
end
Replace the print("Hello World!") line with the code from the GUI if you know it.
