If you're looking for a roblox among us vent script, you've probably noticed that recreating that classic "sus" mechanic is a bit more involved than just teleporting a player from point A to point B. It's one of those features that looks simple on the surface, but once you get into Roblox Studio, you realize there's a whole lot of camera work, animation logic, and UI triggers that need to play nice together.
Creating a functional vent system is basically the rite of passage for anyone trying to build a social deduction game on Roblox. It's the difference between a game that feels like a clunky fan project and one that actually has that polished, tense atmosphere we all love. Let's break down how to get this working without pulling your hair out.
Why the Vent Script is the Soul of the Game
In any Among Us clone, the vents aren't just for decoration. They are the Imposter's lifeline. From a developer's perspective, a roblox among us vent script needs to handle three main things: mobility, stealth, and restriction. You can't just have everyone jumping in and out of the floor—that would ruin the game loop.
When you're coding this, you're essentially building a mini-teleportation system, but with "flavor." You need the player's character to disappear, the camera to follow the vent path, and the player to be "locked" into a state where they aren't technically walking on the map anymore. It's a fun challenge because it touches on several different parts of the Roblox API, like TweenService, ProximityPrompts, and RemoteEvents.
Setting the Foundation in Roblox Studio
Before you even touch a line of code, you need the physical assets. I usually suggest creating a Folder in the Workspace called "Vents." Inside that folder, you'll want your vent models. Each vent should probably have a "CenterPart" or a "TeleportPart" that acts as the exact coordinate where the player will land.
Don't forget the ProximityPrompt. This is the easiest way to handle the interaction. Back in the day, we had to do weird math with Magnitude to see if a player was close enough to a part, but now Roblox gives us prompts that handle the UI and the input for us. Just slap a ProximityPrompt into your vent model, set the "ObjectText" to "Vent," and you're halfway there.
The Logic Behind the Script
So, how does the actual roblox among us vent script function? At its core, it's a client-server relationship. You don't want the teleportation to happen strictly on the client side because other players won't see you move correctly, and it makes it way too easy for exploiters to mess with your game.
Typically, the flow looks like this: 1. The player interacts with the ProximityPrompt. 2. A LocalScript checks if the player is actually an Imposter (don't trust the client for this, but use it for UI feedback). 3. The client fires a RemoteEvent to the server. 4. The server verifies the player's role. 5. The server moves the player's HumanoidRootPart to the vent's location. 6. The server (or client) triggers an animation or a "tween" to make the transition look smooth.
It's that "verification" step that most people skip. If you don't check the player's role on the server, a savvy exploiter could just fire that RemoteEvent whenever they want, even if they're a Crewmate. That's a quick way to get your game rated one star.
Making it Look "Smooth" with TweenService
Nobody likes a jarring "pop" where you're suddenly in a different room. To make your roblox among us vent script feel professional, you should use TweenService.
When a player enters a vent, instead of just setting their CFrame, you can "tween" the camera to a top-down view or move the character slightly downward before they vanish. You can also use a tween to show the vent lid opening. It's these small details that make players feel like they're playing a "real" game.
I personally like to make the character's transparency go to 1 (totally invisible) and disable their controls while they're "inside" the vent system. This prevents them from walking through walls while they're supposed to be underground.
Handling the "Vent Navigation"
In the original Among Us, when you're in a vent, you see arrows pointing to where you can go. This is where the UI comes in. Your roblox among us vent script needs to trigger a ScreenGui for the player.
This GUI should have buttons that, when clicked, tell the server "Hey, move me to Vent B." It's best to keep a table in your script that defines which vents are connected. For example, Vent 1 might connect to Vent 2 and Vent 3. If the player clicks the arrow for Vent 2, you fire another event, and the server does its magic.
Preventing Common Bugs and Glitches
One thing you'll run into—and it's super annoying—is the "player stuck in the floor" bug. This happens if your teleport destination is too low or if the player's character collision messes with the vent model.
To fix this, make sure your teleport destination part is slightly above the floor level, or set the character to Massless temporarily. Also, make sure to disable the CanCollide property on the vent lid while the player is moving through it, or you might find your character being launched into space by the Roblox physics engine.
Another thing to watch out for is the "double vent." Sometimes players will spam the interact key. You should add a "debounce" (a simple cooldown) to your script so that the event can't be triggered more than once every second. This saves your server from unnecessary stress and prevents the player's camera from getting glitched between two locations.
The Security Aspect: Keeping it Fair
Let's talk about the "Imposter" check again because it's so important. When you're writing your roblox among us vent script, you should probably have a Folder in ReplicatedStorage or a Tag via CollectionService that identifies who the Imposters are.
When the RemoteEvent is received by the server, do a simple check: if Player:GetAttribute("IsImposter") == true then -- Proceed with venting else -- Kick them or just ignore the request end
Using Attributes is a really clean way to handle this in modern Roblox development. It's faster than searching for Value objects inside the player and it's easier to manage.
Adding the Final Polish: Sound and Visuals
To really sell the effect, you need sound. A quick "clank" sound when the vent opens and a "whoosh" when moving makes a world of difference. You can trigger these sounds directly from the server so everyone nearby hears the vent opening—giving the Crewmates a chance to catch the Imposter in the act.
You might also want to add a "cooldown" UI on the vent itself. If an Imposter just hopped out, maybe the vent stays slightly ajar or makes a puff of smoke. These are the things that make the gameplay deep and rewarding.
Wrapping it Up
Building a roblox among us vent script is basically a crash course in game flow. You're handling inputs, server-side security, UI, and physical movement all in one go. While it might seem a bit daunting if you're just starting out with Luau, it's a great project to practice your skills.
The biggest takeaway is to keep it modular. Don't write one giant 500-line script. Keep your teleport logic in one place, your UI logic in another, and your security checks on the server. This makes it way easier to fix things when (not if!) something breaks.
Anyway, get into Studio, start playing around with those ProximityPrompts, and see what you can come up with. The best part of Roblox is that you can iterate fast. Test it with a friend, see if they can break it, and then make it even better. Good luck with your game—just don't be too sus while you're coding it!
