To shut a door in Roblox , the usual fix is to script it so it opens, waits a moment, then closes again. A simple pattern from Roblox scripting discussions is to trigger the open action, use a short delay like wait(2) or task.wait(2), then run the close action and add a debounce so it does not fire twice at once.

Simple idea

Use this flow:

  1. Player activates the door.
  2. Door opens.
  3. Script waits 2 seconds.
  4. Door closes.
  5. Debounce resets.

That is the same approach recommended in Roblox developer forum examples for auto-closing doors.

Example logic

lua

local debounce = false

script.Parent.ClickDetector.MouseClick:Connect(function()
	if debounce then return end
	debounce = true

	openDoor()
	task.wait(2)
	closeDoor()

	debounce = false
end)

If your door uses a ProximityPrompt, the same idea still works: open it, wait, then tween or move it back to the closed position.

If your door is tricky

If the door keeps reopening or snapping back, the usual fixes are:

  • Add a debounce.
  • Make sure the close code uses the exact original closed position.
  • Disable extra touch events while the door is moving.
  • Use task.wait() instead of lots of tiny position changes when possible.

No Big Deal note

Your query includes “No Big Deal Roblox,” but the search results mostly point to general Roblox door scripting, not a specific in-game mechanic or official guide for that game. The most reliable answer is still the standard Roblox door-close script pattern above.

TL;DR

Open the door, wait 2 seconds, then close it again, and protect the script with a debounce so it only runs once per interaction.
