How to fast-forward a Tween?

Hello
How can I fast forward / immediately complete a Tween which is being played?

Thanks

I think Tween:Cancel() may immediately fast forward it to its end state but may also just actually reset, have a try

Just play another faster tween and cancel the old one:

local TweenService = game:GetService("TweenService")

local Part = game.Workspace.Part
local tinfo1 = TweenInfo.new(10)

local t1 = TweenService:Create(Part, tinfo1 , { Transparency = 1 })
t1:Play()

--To immidiatly finnish the tween in 0.5 sec for exemple:

if t1 and t1.PlaybackState ~= Enum.PlaybackState.Completed then
	t1:Cancel()
end

local tinfo2 = TweenInfo.new(0.5)
local t2 = TweenService:Create(Part, tinfo2 , { Transparency = 1 })
t2:Play()
