Move a door relative to its starting pose

Mini-mission

Vector3 holds three components and can represent a position or offset. CFrame holds position and orientation. Part.CFrame therefore describes the whole pose.

Capture the closed pose once, then derive the open pose by a local CFrame offset. This preserves the builder’s original orientation.

Your task

Create SlidingDoor and raise it four studs relative to its closed pose after two seconds. Restore its closed pose after two more seconds.

Interface: Complete the documented Studio hierarchy and self-check the behavior outside the browser.

Input	Expected

See another example

local original = marker.CFrame
local raised = original * CFrame.new(0, 2, 0)
marker.CFrame = raised

Multiplication applies the offset in the original local coordinate frame. The orientation remains part of the result.

Your explanation

Self-check rubric

The door stays at its original X/Z location rather than teleporting to the origin.
The closed pose after the return matches the starting pose.

Your explanation is a self-check. Exact wording is not automatically graded.

Self-checked Studio exercise. A saved checklist records your own review; no uploaded place file or screenshot is executed here.

Build this hierarchy

Workspace/SlidingDoor (Part, Anchored=true)
ServerScriptService/DoorPose (Script, RunContext=Server)

Create SlidingDoor with Size 4,6,1 and Position 6,3,0.
Rotate it around Y if you want to observe local versus world offsets.

ServerScriptService/DoorPose.server.luau

Main guided reference implementation; use the hierarchy’s stated Script or ModuleScript type.

local door = game:GetService("Workspace"):WaitForChild("SlidingDoor")
local closed = door.CFrame
local open = closed * CFrame.new(0, 4, 0)
task.wait(2)
door.CFrame = open
task.wait(2)
door.CFrame = closed

Expected output

The door raises four local Y studs, then returns exactly to its starting pose.

Studio assessment checklist

The door stays at its original X/Z location rather than teleporting to the origin.The closed pose after the return matches the starting pose.

Multiplayer tests

Run a local server and at least one client; compare server and client context where the activity uses both.

Troubleshooting and production considerations

Check Anchored and the exact SlidingDoor name.

Repeatedly adding to the current pose can accumulate drift; capture the base pose once.

Explain more

Vector3 holds three components and can represent a position or offset. CFrame holds position and orientation. Part.CFrame therefore describes the whole pose.

Capture the closed pose once, then derive the open pose by a local CFrame offset. This preserves the builder’s original orientation.

Moving an anchored Part by CFrame is a direct pose change in this lab. It is not a physical hinge or a complete door controller.
