Getting your first roblox door script up and running is basically a rite of passage for any aspiring developer on the platform. Think about it—almost every single game you play, from the most complex horror experiences like Doors (ironically) to a simple "Adopt and Raise" roleplay, relies on players being able to move from one room to another. But if you've ever tried to just slap a hinge on a part and hope for the best, you've probably realized that Roblox physics can be a bit temperamental.
The truth is, making a door that actually feels good to use requires a little bit of Luau magic. You don't want a door that just teleports out of the way, and you definitely don't want one that flings the player across the map because of a collision glitch. We're going to look at how to build a door that's smooth, reliable, and easy to customize.
Why You Should Avoid Physics-Based Doors
When you're starting out, your first instinct might be to use constraints or HingeConstraints. While those are cool for vehicles or pendulums, they can be a nightmare for doors. If a player stands in the way, the physics engine might freak out. If two players try to push it at once, it might get stuck.
That's why most seasoned devs prefer a roblox door script that utilizes TweenService. Tweening allows you to animate properties—like position or rotation—over a set period of time. It's predictable, it's smooth, and it doesn't care if a stray "noob" character is clipping through the frame.
Setting Up Your Door Model
Before we even touch the script, we need to build the door correctly. This is where most people mess up. If you just rotate a part in the middle, it spins like a propeller. Doors need to swing from an edge.
- The Door Frame: Create a simple frame using three parts. Anchor these. They aren't going anywhere.
- The Door Slab: Create the actual door part. Call it "Door." Do not anchor it yet (actually, we will anchor it in the script, but let's keep it simple for now).
- The Hinge: This is the secret sauce. Create a tiny, invisible part (transparency = 1) and place it exactly where the door's hinges would be. Call this "Hinge."
- Welding: You'll want to weld the "Door" part to the "Hinge" part. This way, when the Hinge rotates via our script, the Door follows it perfectly.
Once you have your Hinge and Door welded together, make sure the Hinge is Anchored and the Door is Not Anchored. This allows the script to move the Hinge, which in turn moves the door.
Writing the Basic Script
Let's get into the actual code. We're going to use a ProximityPrompt because clicking on doors is a bit old-school, and prompts work way better for mobile and console players.
Inside your Hinge part, add a ProximityPrompt and then a Script. Here's a simple version of what that roblox door script should look like:
```lua local TweenService = game:GetService("TweenService") local hinge = script.Parent local prompt = hinge:WaitForChild("ProximityPrompt")
local isOpen = false local debounce = false
-- This defines how the movement looks local tweenInfo = TweenInfo.new( 0.5, -- Speed (seconds) Enum.EasingStyle.Quart, Enum.EasingDirection.Out )
-- Goal positions local openGoal = {CFrame = hinge.CFrame * CFrame.Angles(0, math.rad(90), 0)} local closedGoal = {CFrame = hinge.CFrame}
local openTween = TweenService:Create(hinge, tweenInfo, openGoal) local closedTween = TweenService:Create(hinge, tweenInfo, closedGoal)
prompt.Triggered:Connect(function() if debounce then return end debounce = true
if not isOpen then openTween:Play() prompt.Acti isOpen = true else closedTween:Play() prompt.Acti isOpen = false end wait(0.6) -- Matches the tween time plus a little extra debounce = false end) ```
Breaking Down the Logic
Notice how we used math.rad(90)? Roblox uses radians for rotation, not degrees. If you just put "90" in there, your door is going to spin around like it's possessed. Converting degrees to radians keeps things human-readable for us.
The debounce variable is also super important. Without it, a player could spam the "E" key and start fifty different animations at once. That's a one-way ticket to a broken door and a very confused script. By using a debounce, we tell the script to "ignore all inputs until the current movement is finished."
Adding Some "Juice" to Your Door
A door that moves silently is kind of creepy. To make your game feel more professional, you should add sound effects. Grab a "Door Open" and "Door Close" sound from the Roblox audio library.
Put them inside the Door part and call them "OpenSound" and "CloseSound." Now, inside your script, just call hinge.OpenSound:Play() right before the tween starts. It's a tiny change, but it makes the world of difference for immersion.
You can also change the EasingStyle. If you want a heavy vault door, use Enum.EasingStyle.Bounce. If you want a high-tech sliding door, use Enum.EasingStyle.Linear. Experimenting with these styles is how you find the "vibe" of your game.
Making a Sliding Door
Not every door swings. If you're building a sci-fi lab, you probably want those cool sliding panels. The good news? The roblox door script logic is almost identical. Instead of changing the CFrame.Angles (rotation), you just change the Position.
Instead of a Hinge, you can just tween the Door part itself. Your "openGoal" would look something like this: local openGoal = {Position = door.Position + Vector3.new(0, 8, 0)} (This would make the door slide upward).
Handling Security and Latency
If you're making a multiplayer game, you might notice that sometimes doors look a bit "stuttery" for players with bad internet. This happens because the server is handling the animation.
A pro tip for later in your dev journey is to handle the logic on the server (like checking if the player has a keycard) but handle the animation on the client using a RemoteEvent. This makes the door move instantly for the player who touched it, while everyone else sees it move smoothly a split second later. Don't worry about this too much for your first few builds, but it's good to keep in mind once your game starts getting popular.
Common Pitfalls to Watch Out For
Even with a solid roblox door script, things can go sideways. Here are the most common reasons your door isn't working:
- The "Flying Away" Glitch: If your door is welded but not properly anchored (or vice versa), it might fly off into the void the moment the game starts. Always double-check your Anchored properties.
- CanCollide Issues: If your door is part of a wall, make sure the door slab itself has
CanCollideturned on, but the frame doesn't block it from moving. - The Wrong Script Type: Make sure you're using a
Script(Server-side) and not aLocalScript. If you use a LocalScript, only you will see the door open; other players will see you walking through a solid wall like a ghost.
Wrapping It Up
At the end of the day, a roblox door script is a building block. Once you master the basic open/close logic, you can start adding requirements—like needing a specific "Key" tool in your backpack or checking if a player is on a certain team before the ProximityPrompt even shows up.
The best way to learn is to take the script above, throw it into a project, and start breaking things. Change the numbers, swap the sounds, and see what happens. Before you know it, you'll be designing complex airlocks and hidden revolving bookshelves. Happy building!
