Is there a way to tween a CFrame's orientation without changing the position?

[Edicelsuper (dug)]

Just to make it clear what I mean: I do NOT mean CFrame = part.CFrame * CFrame.Angles

Imagine a part is already moving/being tweened, is there a way to make a 2nd tween that changes purely the part’s orientation through cframes without changing the position or am I forced to tween purely the orientation without cframes? Because if you try to tween with CFrame =part.CFrame * CFrame.Angles while the part is moving then it’ll constantly try to stick to one position and it starts glitching out

maybe?

local position = part.Position
local targetRotation = CFrame.Angles(math.rad(x), math.rad(y), math.rad(z))
local goalCFrame = CFrame.new(position) * targetRotation

Already tried that solution from a different forum, doesnt work (basically for the same reason as ive said in the message)

what about this:

local part = workspace.Part
part.CFrame *= CFrame.Angles(math.rad(90), 0, 0)

That’s literally what I wrote in my post

ok sorry i didn’t read past the title. but you can’t really do what you’re describing with tweens. you’re going to have to use a heartbeat loop or a while loop to update the cframe

Just combine your goal CFrame with your orientation CFrame.

local TweenService = game:GetService("TweenService")
local part = [yourPart]
local goalPart = [yourGoalPart]

local goalPosition = goalPart.Position
local xRot, yRot, zRot = part.CFrame:ToOrientation()

local moveAndRotate = TweenService:Create(
part,
TweenInfo.new(5),
{CFrame = CFrame.new(goalPosition) * CFrame.Angles(xRot, math.rad(90), zRot)}
)

moveAndRotate:Play()

The point is that the part is already moving by the time you’re doing the second tween, that’s why Im asking the question in the first place

[DarstrialB]

So you don’t want to rotate the part in the initial moving tween, you want to rotate the part during the moving tween?

[Edicelsuper (dug)]

Yup

Sorry for the long wait!! I had to do some testing with this. Here’s how you can pull it off:

local TweenService = game:GetService("TweenService")
local RunService = game:GetService("RunService")

local part = [yourPart]
local tweenConnection : RBXScriptConnection = nil

-- create the values --
local rotationValue = Instance.new("CFrameValue"); rotationValue.Parent = script
local x, y, z = part.CFrame:ToOrientation(); rotationValue.Value = CFrame.Angles(x, y, z)
-- pretty self explanatory, set the value to the current orientation

local positionValue = Instance.new("Vector3Value"); positionValue.Parent = script
positionValue.Value = part.Position
-- also pretty self explanatory, set the value to the current position

-- our goals --
local goalPosition = [yourGoalPosition]
local goalRotation = CFrame.Angles(0, math.rad(90), 0)

-- tweens --
local positionTween = TweenService:Create(
	positionValue,
	TweenInfo.new(10),
	{Value = goalPosition}
)

local rotationTween = TweenService:Create(
	rotationValue,
	TweenInfo.new(5),
	{Value = goalRotation}
)

positionTween:Play()

tweenConnection = RunService.Heartbeat:Connect(function()
	part.CFrame = CFrame.new(positionValue.Value) * rotationValue.Value
end)
-- here we set up a connection that will constantly calculate our orientation & position 
-- each heartbeat, preventing tween overlap which was your issue.
-- because [rotationValue.Value] is the part's current rotation at the time
-- of setting this up there's no jarring changes to the part's orientation.

task.wait(5)

rotationTween:Play()

positionTween.Completed:Once(function()
	if tweenConnection.Connected then
		tweenConnection:Disconnect()
	end
	tweenConnection = nil
end)
-- we stop listening for RunService.HeartBeat because the tween has ended.

This method supports EasingStyle and EasingDirection as well! Hope this works for you.
