Tweening Part - Orientation bug

Help and Feedback Scripting Support
#1

Hello,
I’m trying to make ticket gates for my game, and for the most part, it works just fine. However on the ones that I have flipped 180 for people passing in the other direction, the right barrier’s tweening takes the “long way” to get to/from the “open” orientation, by spinning round rather then just moving the short way. I’ve probably explained this horribly, so I’ll attach a video:

Notice how its only the right side barrier that does this.

The movement of the barriers is done through Tweening:

local function openR()
	local TweenService = game:GetService("TweenService")
	local part = rclosed
	local goal = {}
	goal.Position = Vector3.new(ropen.Position.X, ropen.Position.Y, ropen.Position.Z)
	goal.Orientation = Vector3.new(ropen.Orientation.X, ropen.Orientation.Y, ropen.Orientation.Z)
	local tweenInfo = TweenInfo.new(1)
	local tween = TweenService:Create(part, tweenInfo, goal)
	tween:Play()
	wait(0.1)
	rclosed.CanCollide = false
	wait(2)

	--close
	lclosed.CanCollide = true
	local TweenService = game:GetService("TweenService")
	local part = rclosed
	local goal = {}
	goal.Position = Vector3.new(rorigin.Position.X, rorigin.Position.Y, rorigin.Position.Z)
	goal.Orientation = Vector3.new(rorigin.Orientation.X, rorigin.Orientation.Y, rorigin.Orientation.Z)
	local tweenInfo = TweenInfo.new(1)
	local tween = TweenService:Create(part, tweenInfo, goal)
	tween:Play()

end

^ The function for the right side barrier opening/closing. If you need to see the whole script I can provide that too.

I’m not sure how to get around this problem. One thing that I have noticed is that when the whole model is rotated 180 degrees, both barriers work fine, and without issue. I do not see how the model’s orientation itself would affect this though, as I use the invisible “open barriers” and use their positions/orientations to allow the script to always know where the correct open position is.

I know I’ve explained this horribly so I apologise in advance, but I hope you can at least understand what I mean. Any help would be greatly appreciated :slight_smile:

Tweening uses the most efficient path towards achieving your tween goal. The issue you are having here is most likely because you have somehow tweened the gate past 180* (from its original point) which means if you then try to close it, it’ll go “backwards” to get to your goal.

Perhaps try 179* instead.
