Keeping un-anchored parts on tweening objects (Cabinet style)

[Korrow (Peter)]

I have made a cabinet (using @colbert2677’s concept)

Introduction to Tweening Models

Note (06/30/2021): Due to the release of the new pivot APIs and the thankful deprecation of SetPrimaryPartCFrame, the legacy method of CFraming is now also appropriate and you do not necessarily need to use this welding method. Do note that the pivot CFrame is different from the PrimaryPart CFrame though, so you will have to account for that when writing your proxy objects.

And I want to move the items that are inside the cabinet relatively to the movement.
Now, the cabinet is anchored but the key however, is not.
Here is a brief gif of my issue:

This is the key being un-anchored:

You can see my issue, I want to prevent myself from using body movers to open/close the cabinet and stuff because Colbert’s method works too well for me, and I can use different easing styles on it.

I know the issue might be because it’s CFraming the entire model instead of physically moving it, and that’s where I need some help.

local tw = ts:Create(script.Parent.Base,TweenInfo.new(.7,Enum.EasingStyle.Quad,Enum.EasingDirection.Out),{CFrame = script.Parent.Base.CFrame * CFrame.new(0,0,-2)})

As you can see the “Base” is the bottom part, which the entire cabinet is welded to.

You could just weld the key onto the cabinet drawer itself, I think this will solve the issue.

This is a work-around, which is good enough for my current issue!
(idk how i didnt think of that)
