While loop tween problem

[04robot48 (Robotstics)]

I’m trying to create an obstacle in my obby that sweeps across the floor and back using tweens. The tween repeats by wrapping the function in a while loop. However, as you can see in the clip, when the reverse tween plays it’s abruptly stopped and the first tween plays, creating a loop where the reverse tween keeps on getting interrupted.

Here’s my code:

local sweepIntervalAndStyle = TweenInfo.new(5, Enum.EasingStyle.Linear)

local sweepingKillbrickGoal = {
	Position = Vector3.new(9.423, 9.718, -98.921)
}

local reverseSweepingKillbrickGoal = {
	Position = Vector3.new(9.423, 9.718, -162.497)
}

local sweepTween = TweenService:Create(sweepingKillbrick, sweepIntervalAndStyle, sweepingKillbrickGoal)

local reverseSweepTween = TweenService:Create(sweepingKillbrick, sweepIntervalAndStyle, reverseSweepingKillbrickGoal)

function SweepAndReverse()
	sweepTween:Play()
	sweepTween.Completed:Connect(function()
		reverseSweepTween:Play()
	end)
end

while true do
	task.wait(0.5)
	SweepAndReverse()
end

For some reason, the problem fixes itself if I call SweepAndReverse() normally without using a while loop. However, I want the sweeping to repeat. Help would be majorly appreciated.

Try waiting for each tween to prevent them from getting interrupted.

function SweepAndReverse()
	sweepTween:Play()
	sweepTween.Completed:Wait()
	reverseSweepTween:Play()
	reverseSweepTween.Completed:Wait()
end

while true do
	SweepAndReverse()
end

You can condense this further by using the tween itself as a loop by using -1 on repeat count and reverses to true making the while true do and reverse tweens unnecessary
