Tween stops inside a loop

[Selddy]

I’m trying to make a part spin without stopping using a tween. But when I run it, it looks like the tween plays once and then stops even though it’s inside a loop. What’s the issue here?

local tweenService = game:GetService("TweenService")

local spinPart = script.Parent.SpinPart

local goal = {}
goal.CFrame = spinPart.CFrame * CFrame.Angles(3, 0, 0)

local tweenInfo = TweenInfo.new(1)
local tween = tweenService:Create(spinPart, tweenInfo, goal)

while true do
	tween:Play()
	tween.Completed:Wait()
end

When the Tween finishes, its at its ‘finish’ position. When you start the tweet again, since the part is already at its ‘finish’ position, it won’t move because it’s done already. In your loop you have to define new tween settings.

Not the best with Tweens but pretty sure you gotta write it like this:

local spinPart = script.Parent.SpinPart

while true do

        local goal = {}
goal.CFrame = spinPart.CFrame * CFrame.Angles(3, 0, 0)

        local tweenInfo = TweenInfo.new(1)
        local tween = tweenService:Create(spinPart, tweenInfo, goal)

        tween:Play()
	tween.Completed:Wait()
end

When tween:Play() is done a second time, spinPart has already reached its target. that is why the spinning stops.
the target must be updated on each iteration.

local tweenService = game:GetService("TweenService")

local spinPart = script.Parent.SpinPart

local goal = {}

local tweenInfo = TweenInfo.new(1)

while true do
    goal.CFrame = spinPart.CFrame * CFrame.Angles(3, 0, 0)
    local tween = tweenService:Create(spinPart, tweenInfo, goal)
    tween:Play()
    tween.Completed:Wait()
end
