Tweening a door doesn't cause collision with other objects

I’m trying to make a door using tweens, but when I have other unanchored objects near it, they don’t collide with the door.


Here’s the code if it helps.

local ts = game:GetService("TweenService")

local hinge = script.Parent:WaitForChild("Hinge")
local openT = ts:Create(hinge, TweenInfo.new(.5, Enum.EasingStyle.Sine, Enum.EasingDirection.Out), {CFrame = hinge.CFrame * CFrame.Angles(0, math.rad(90), 0)})
local closeT = ts:Create(hinge, TweenInfo.new(.5, Enum.EasingStyle.Sine, Enum.EasingDirection.Out), {CFrame = hinge.CFrame})

local open = false
local opening = false

local remote = script.Parent:WaitForChild("Door"):WaitForChild("Interact")

remote.OnServerEvent:Connect(function(player)
	if opening then return end
	opening = true
	open = not open
	if open then
		openT:Play()
	else
		closeT:Play()
	end
	wait(.5)
	opening = false
end)

From my experience, TweenService and physics objects don’t blend well together.
Usually when I code doors that collide with physics objects, I use CFrame:Lerp() to create my own tween, if you will.

Here’s an example of an interpolating function that achieves your goal using CFrame:Lerp():

local rs = game:GetService("RunService")
local hinge = script.Parent.Hinge

local function dosomestuff(cf)
	for i = 1, 30 do
		hinge.CFrame = hinge.CFrame:Lerp(cf, math.sin(math.rad(i * 3)))
		rs.Stepped:Wait()
	end
end

Doesn’t seem to work either, might just be an issue with roblox’s physics generally.
Might look into using some kind of constraint of some sort instead

I’ve tested it for myself, and it does seem to work for me. Gonna sound strange, but did you check to make sure that CanCollide is true?

If that still doesn’t work, you can try modifying the function to use welds instead. Welds are usually a good choice for doors who are being stubborn. Changing the function to change a weld C0 / C1 instead of the hinge’s CFrame should do the trick.

Yeah i’ve figured it out - I think it’s based on part size.
CanCollide is on for every object there. That’s the first thing I checked.
Larger parts seem to collide fine, after some testing
