Making a rotated brick grow only one one side?

Hello, I'm trying to make some kind of trapdoor,

The way it works is like this:

When you close it, it kind of slides and grows so that you have the impression it is closing. A little like a garage door but on the ground.

I'm trying to find the exact formula to make it look good.

So far I have :

h1.Size=Vector3.new(h1.Size.X+.482,h1.Size.Y,h1.Size.Z) h1.CFrame=CFrame.new(q1.X-.241,q1.Y,q1.Z+.0241)*CFrame.Angles(math.rad(0),math.rad(15),math.rad(-0))

But that wont work.

h1 being the door part and q1 being its position

I googled some stuff I think it has to do with logarithms, anyone help? I have no idea what it is KoreanBBQ 301 — 9y

Why not just translating it to the side? Or use a block mesh and have the Scale & Offset properties manipulated quickly? Redbullusa 1580 — 9y

I can't translate it to the side because then you would see it through the other side. And Offsets with Meshes work just like Scale, it wouldn't help because it resizes on bot sides KoreanBBQ 301 — 9y

Offset's different from Scale. Offset translate it while Scale resizes it. If you use both of them at the same time, it'll simulate a "grow" or "shrink" effect. Redbullusa 1580 — 9y

Oh yeah you're right I could use Offset but I'd rather have the actual object to move, because it could mess up with some Touched events or stuff like that KoreanBBQ 301 — 9y

Are you talking about turning a square into a trapezoid? JasonTheOwner 391 — 9y

Free model is here

Here's some code that should work.

Note - use the Front Surface as the edge of the door that closes, and increment must be greater than one. I used 1.01

Put this in a server script...

No I've made better doors that that in the past, and I dont want them to only slide, I also want them to resize KoreanBBQ 301 — 9y

Alrighty - I'll put a free model together of one that resizes. I was going to go with a resizing idea, when I did this one, but decided to go with a slider. Keep in mind, that door is all about the scripting - you can design it however you want LOL JasonTheOwner 391 — 9y

What if it rotated open like a garage door? You really want it to resize right? JasonTheOwner 391 — 9y

Nevermind I put a new set of code together that I tested and it seems to work. JasonTheOwner 391 — 9y
