How to Make NPC Dialogue in Roblox

Step 1: Set Up the NPC Model and ProximityPrompt

In Roblox Studio, insert an R15 or R6 character rig from the Avatar tab. To prompt interaction when players approach:

1. 1 Locate the NPC model in the Explorer and find its `HumanoidRootPart`.
2. 2 Click the + icon beside `HumanoidRootPart` and insert a ProximityPrompt.
3. 3 In the Properties panel, set `ActionText` to “Talk”, `ObjectText` to the NPC’s name, and `HoldDuration` to 0.5 seconds.

Step 2: Generate the Dialogue Script

Writing dynamic branching conversations with variables and quest conditionals can quickly become complex. You can generate ready-to-run dialogue scripts and character lines using our NPC Dialogue Generator.

Step 3: Trigger the Dialogue UI (Client Script)

When the ProximityPrompt is triggered, open your dialogue ScreenGui and display the text. Add a LocalScript inside your dialogue frame:

local prompt = workspace.NPC.HumanoidRootPart:WaitForChild("ProximityPrompt")
local dialogueFrame = script.Parent
local textLabel = dialogueFrame:WaitForChild("DialogueText")

local message = "Greetings, traveler! Are you ready to embark on this quest?"

prompt.Triggered:Connect(function()
	dialogueFrame.Visible = true
	textLabel.Text = ""
	
	-- Typewriter effect
	for i = 1, #message do
		textLabel.Text = string.sub(message, 1, i)
		task.wait(0.03)
	end
end)
