Issues with tweens

Help and Feedback Scripting Support
#1

Hi there! I made a script and I would like to know how to only change Y position with a Tween to avoid tweens conflicts. Can you help me please?

#2

Hello. In the properties table of your tween, try doing Position.Y instead of Position.

#3 
local pos = Part.Position --assuming you aren't using CFrame
local offset = 5 --5 studs per tween
--tween goal-propertiesTable 
local goal = {
	Position = Vector3.new(pos.X, pos.Y+offset, pos.Z)
}

PS: The properties of constructors like CFrame, Vector3, Color3 etc. cannot be set directly(for example pos.Y += 5).

So, how to avoid tween conflicts between a tween which only modify position.X and a tween which only modify position.Y? Roblox should make this possible.

#5

Do not store the starting position in a variable: Vector3.new(Part.Position.X, Part.Position.Y+offset, Part.Position.Z)

Is this work to avoid conflicts between two tweens which modify value of two different axis on the same part?

You shouldnt have two tweens on a single part. Instead try doing it with one tween.

#8

This must also be applied to the tween which changes the X axis.

If I have a part which is spinning by using a Cylindrical Constraint and I want to change the CFrame of this part to modify his position, the part will stop spinning during a while and I don’t want it freeze each time it happen.
If I change the position of this part, parts attached to it by using welds will stay at the same place.

#10

I’m not sure what you are trying to say, but changing the CFrame while trying to keep the effect of the cylindrical constraint wouldnt work with a tween because CFrame unlike position also holds the orientation of the part

#11

That this the problem. I want to change the CFrame without change his orientation.

#12

Then you should change the position and not the CFrame

#13

Some parts are attached to the spinning part with weld constraints. If I use the position instead of CFrame, welded parts will stay at the same place.

#14

What do you mean exactly . . ?

#15

Here is how you would tween something’s CFrame without changing the orientation:

local partRotation = part.CFrame - part.Position

local yourTween = TweenService:Create(part, tweenInfo, {
CFrame = CFrame.new(x Position, y Position, z Position) * partRotation
})

So a practical example would be:

local part = workspace.PartToMove

local rotation = part.CFrame - part.Position

local tweenInfo = TweenInfo.new(3)

local movePartUp = TweenService:Create(part, tweenInfo, {
CFrame = CFrame.new(0, 20 , 0) * rotation
})

movePartUp:Play()

Hope this helps!

You can’t change one value of a Vector3 directly.
