Code only works in Studio

[TheRealMrSquirrel (MrSquirrel)]

When engaging with an NPC within the Roblox editor, the dialog consistently opens every time. However, upon publishing to Roblox and playing the game, the dialog functions only during the initial interaction. If the player exits and rejoins, the dialog fails to reopen.

In my initial attempt to address this issue, I modified the following line of code:

From:

local player = game.Players.LocalPlayer

To:

local player = Players.LocalPlayer

This adjustment enabled the dialog to function for the first encounter but did not resolve the issue of it failing to reopen upon subsequent player exits and rejoins.

Rest of Code

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local TweenService = game:GetService("TweenService")
local DialogModule = require(ReplicatedStorage.DialogModule)
local p = Players.LocalPlayer
local NPCs = workspace.NPCs
local DialogFrame = script.Parent.DialogFrame
local InputButton = DialogFrame.Input
local NPCName = DialogFrame.NPCName
local player = Players.LocalPlayer


local DIALOG_TWEENINFO = TweenInfo.new(0.25, Enum.EasingStyle.Exponential, Enum.EasingDirection.Out)

local dialogOpen = false
local dialogTween = nil
local dialogIndex = 0
local gradualTextInProgress = false


local function gradualText(text)
	if gradualTextInProgress then
		return
	end
	
	local length = string.len(text)
	
	for i = 1, length, 1 do
		gradualTextInProgress = true
		DialogFrame.DialogText.Text = string.sub(text, 1, i)
		wait()
	end
	
	gradualTextInProgress = false
end

local function onDialog(dialog, index, proximityPrompt)
	if dialog[index] then
		gradualText(dialog[index])
	else
		if dialogTween then
			dialogTween:Cancel()
			dialogTween = nil
		end
		local tween = TweenService:Create(DialogFrame, DIALOG_TWEENINFO, {
			Position = UDim2.new(0, 0, 2, 0)
		})
		dialogTween = tween
		dialogTween:Play()
		proximityPrompt.Enabled = true
		dialogOpen = false
		dialogIndex = 0  
		p.Character.HumanoidRootPart.Anchored = false
	end
end

InputButton.MouseButton1Click:Connect(function()
	if gradualTextInProgress then
		return
	end

	local dialog = DialogModule[NPCName.Value]
	dialogIndex = dialogIndex + 1  
	onDialog(dialog, dialogIndex, NPCs[NPCName.Value].HumanoidRootPart.ProximityPrompt)
end)


for _, NPC in pairs(NPCs:GetChildren()) do
	local humanoidRootPart = NPC:FindFirstChild("HumanoidRootPart")
	local proximityPrompt = humanoidRootPart:FindFirstChild("ProximityPrompt")
	
	if humanoidRootPart and proximityPrompt then
		proximityPrompt.ObjectText = NPC.Name
		proximityPrompt.ActionText = "Chat with " .. NPC.Name
		
		local dialog = DialogModule[NPC.Name]
		
		proximityPrompt.Triggered:Connect(function()
			if dialogOpen then
				return
			end
			
			dialogOpen = true
			proximityPrompt.Enabled = false
			NPCName.Value = NPC.Name
			p.Character.HumanoidRootPart.Anchored = true
			
			if dialogTween then
				dialogTween:Cancel()
				dialogTween = nil
			end
			local tween = TweenService:Create(DialogFrame, DIALOG_TWEENINFO, {
				Position = UDim2.new(0, 0, 1, 0)
			})
			dialogTween = tween
			dialogTween:Play()
			
			dialogIndex = 1
			onDialog(dialog, dialogIndex, proximityPrompt)

		end)
	end
end

Is this in a local script or server script?

[TheRealMrSquirrel (MrSquirrel)]

This is a Local Script

Word Count

[MikeartsRBLX (Brimstone)]

not sure if this is the main issue but you defined 2 players

local p = Players.LocalPlayer
– and
local player = Players.LocalPlayer

and where is the script located?
