Having trouble getting UpVector while tweening to make a rocket, is there any solution to this?

Hello,

Im currently trying to figure out how to make a spaceship with the roblox TweenService and its all going good so far until i started 'tweening', there is nothing 'wrong' with my code. I want to get the UpVector of a part and tween it from there but the parts instead of going straight up they go a little to the side.

01local tweenService = game:GetService("TweenService")
02 
03-- These three parts are wielded together with stage 2 as 'center' part
04local Stage1 = script.Parent:WaitForChild("Stage1")
05local Stage2 = script.Parent:WaitForChild("Stage2")
06local finalStage = script.Parent:WaitForChild("FinalStage") --
07 
08local studs = script.Parent:WaitForChild("Studs").Value -- how high up it should go (set to 50)
09 
10local stage1Fire = Stage1:WaitForChild("Fire"):WaitForChild("ParticleEmitter") -- ignore this
11 
12local luanchButton = script.Parent:WaitForChild("Luanch"):WaitForChild("Detector")
13 
14local tweenInfo = TweenInfo.new(
15    script.Parent.MaxVel.Value / 60, -- just so i could set studs per minute
16    Enum.EasingStyle.Quad,
17    Enum.EasingDirection.In,
18    0,
19    false,
20    0
21)
22 
23local function luanch()
24    local properties = {
25        CFrame = CFrame.new(Stage2.CFrame.UpVector * Vector3.new(1, studs, 1)) -- I think its somwhere here the problem is.
26    }
27 
28    local tween = tweenService:Create(Stage2, tweenInfo, properties)
29 
30    tween:Play()
31end
32 
33luanchButton.Triggered:Connect(luanch) -- Im using a ProximityPrompt 
 View all 33 lines...

I have created a video here if i have been bad at explaning

Thanks for taking your time!

Yes the problem is indeed on line 25.

Instead of this.

`1`	`CFrame` `=` `CFrame.new(Stage2.CFrame.UpVector * Vector3.new(1, studs,` `1))`

It should be this.

`1`	`CFrame` `=` `Stage2.CFrame + Stage2.CFrame.UpVector * studs`

This is because UpVector returns a Vector3 value that is 1 stud above the Intance, so then you can multiply it with an number to make it higher. Then you add the CFrame of the Instance so it combines the rotation and position together.

I hope you understand and that this helps!

Thanks, it really helped! Love_LoL01 7 — 4y
