How do you use the SetAttibute function on a tween object to change the tween time?

  1. What do you want to achieve?
    I want to be able to change the time attribute for an already instantiated tween object.

  2. What is the issue?
    I’m calling the SetAttribute function on a tween object as such:

local tweenTime = 3.5
local newTweenTime = 2.5

local tweenInfo =, Enum.EasingStyle.Linear, Enum.EasingDirection.Out)
local tweenProperties = {}
tweenProperties.Position =, 0, 0, 0)
tweenProperties.Size =, 0, 1, 0)

local tween = TweenService:Create(guiObject, tweenInfo, tweenProperties)


tween:SetAttribute("Time", newTweenTime)

After I try setting the time attribute, I get the following error:
Attributes are not currently enabled

  1. What solutions have you tried so far?
    I’ve searched the Dev Forums and couldn’t find anything.

Attributes are not released yet. And don’t tweens already have a Time property?


They do but I think it’s read only. Is there any way of changing the time of a tween without having to recreate it?

Why do you want to do this? Why not just :Play() the tween?

Sometimes the tween will need to play slow and other times I want it to animate faster.

In that case just use a lower time for

I know you said you didn’t want this but it looks like it’s the only way.

Attributes are separate from properties. Setting the Time attribute of a tween will not influence its Time property.

It is impossible to change the time progress of a tween.

Alright, no worries. I’ll just recreate the tween using new TweenInfo.
