How would I make an efficient typewriter effect?

[notseventysix (cookiemonster)]

Hi, I’m making a tutorial for my game and I’m using a simple typewriter effect. But I’ve been finding it tedious to copy and paste the function and then change the text in the text label, is there a more efficient way to do this?

Not sure what you mean by copy pasting, but you can use this typewriter:

Animating Text

-- You can edit the Text Variables if you want to.
local TextLine1 = "EDIT TEXT HERE 1"
local TextLine2 = "EDIT TEXT HERE 2"
local TextLine3 = "EDIT TEXT HERE 3"
local TextLine4 = "EDIT TEXT HERE 4"
local TextLine5 = "EDIT TEXT HERE 5"

local IntervalTime = 2

while wait(IntervalTime) do
	
	for T = 1, #TextLine1 do
		script.Parent.Text = string.sub(TextLine1, 1, T)
		wait(0.1)
	end		
	
	wait(IntervalTime)
	
	for T = 1, #TextLine2 do
		script.Parent.Text = string.sub(TextLine2, 1, T)
		wait(0.1)
	end		
	
	wait(IntervalTime)
	
	for T = 1, #TextLine3 do
		script.Parent.Text = string.sub(TextLine3, 1, T)
		wait(0.1)
	end		
	
	wait(IntervalTime)		
	
	for T = 1, #TextLine4 do
		script.Parent.Text = string.sub(TextLine4, 1, T)
		wait(0.1)
	end	
	
	wait(IntervalTime)
	
	for T = 1, #TextLine5 do
		script.Parent.Text = string.sub(TextLine5, 1, T)
		wait(0.1)
	end			
	
end

Yep, however for a more advanced version which takes into account lag and fps changes, the delta time version.

When the time it takes to resume wait() changes, text will appear slower. Under normal circumstances this will work fine, but if the frame rate drops or there are too many threads to be resumed in one frame the wait() will take longer to resume, making the text appear slower.

Choosing to wait for a RunService event ( Heartbeat:Wait() , Stepped:Wait() , RenderStepped:Wait() ), will still make it susceptible to a drop in frame rate.

Example: Typewriter effect using DeltaTime

local RunService = game:GetService"RunService"
local Heartbeat = RunService.Heartbeat
local Goal = "Some text that should appear after some time."
local GoalLength = #Goal
local TimeToTake = GoalLength/30
local Accumulated = 0
while TimeToTake > Accumulated do
	Accumulated += Heartbeat:Wait()
	TextElement.Text = string.sub(Goal,1,math.floor((Accumulated/TimeToTake)*GoalLength))
end

With this, whenever the frequency of Heartbeat firing changes, the rate at which the text appears won’t change.

Thanks, but the bug still shows up when you search anything.

It just endlessly loads then shows no results.

I don’t think this has any relation to the topic but try reloading roblox studio or reinstall it, that should fix your problem. Also check your wifi
