If you're tired of seeing players zip across your map in seconds, you definitely need a solid roblox anti teleport script to keep things fair. It is honestly one of the most frustrating things as a developer. You spend weeks, maybe months, balancing your game's economy or designing a perfect obstacle course, only for someone to join and use a cheap exploit to teleport straight to the finish line. It ruins the vibe for everyone else and can totally tank your player retention.
The reality is that Roblox is a physics-based engine, and because of how the client-server relationship works, players have a certain amount of "authority" over their own character's position. This is great for smooth movement, but it's a massive loophole for exploiters. Fortunately, we can close that loop with some relatively straightforward scripting logic.
Why You Can't Trust the Client
Before we even look at a single line of code, we have to talk about the most important rule in Roblox development: Never trust the client. If you put your anti-cheat script inside a LocalScript, an exploiter is just going to find it and delete it. It's like putting a "Do Not Enter" sign on a door but giving the key to the person you're trying to keep out.
For a roblox anti teleport script to actually do its job, it has to run on the server (a regular Script in ServerScriptService). The server needs to be the "source of truth." It should constantly check where the player is versus where they were a second ago. If the distance between those two points is physically impossible for a normal character to walk, you know something fishy is going on.
The Basic Logic: Distance over Time
At its heart, teleport detection is just a bit of math. We know how fast a standard Roblox character moves (usually a WalkSpeed of 16). If a player moves 300 studs in half a second, they're clearly not walking.
To detect this, we use the Magnitude property of vectors. In Luau, (PositionA - PositionB).Magnitude gives us the exact distance between two points in 3D space. By tracking a player's position at regular intervals, we can see if they've "jumped" too far.
Setting Up the Detection Loop
You don't want to check every single frame because that's a bit hard on the server's performance, especially if you have 50 players in a server. A check every 0.5 or 1 second is usually plenty.
Here's the general flow: 1. Store the player's current position. 2. Wait a brief moment. 3. Get the player's new position. 4. Calculate the distance between the two. 5. If the distance is greater than the (WalkSpeed * Time) + a small buffer, trigger an action.
Handling False Positives (The Real Challenge)
This is where most beginner developers run into trouble. If you're too strict with your roblox anti teleport script, you'll end up kicking players who are just lagging. We've all been there—your internet hiccups, your character freezes for a second, and then suddenly you "teleport" forward when the data finally catches up.
If your script kicks someone for that, they're probably going to leave a dislike on your game and never come back. To avoid this, you need to build in a "buffer" or a "grace" system.
Account for Lag and Physics
Instead of instantly kicking a player the first time they move too fast, give them a "violation" point. If they reach 3 or 5 violations in a short period, then you take action. Also, make sure your script ignores players who are sitting in vehicles or players who have just respawned, as those involve legitimate, massive shifts in position.
The Buffer Zone
If a player's WalkSpeed is 16 and you check every second, don't set your limit exactly at 16. Gravity, jumping, and slight network jitter can easily push that distance to 20 or 25. Setting a threshold of 40 or 50 studs usually catches the exploiters while leaving the regular players alone.
What Should the Script Do?
When you catch someone teleporting, you have a few options.
1. The Kick: This is the nuclear option. The player gets a "You have been kicked" screen. It's effective, but if your script has a bug, you're losing players for no reason.
2. The Rubber-Band: This is my personal favorite for most games. Instead of kicking them, you just teleport them back to their "Last Known Good Position." It makes the exploiter's life miserable because they can't go anywhere, but if a player just had a lag spike, they just feel a little "tug" back to where they were.
3. The Log: If you're worried about false positives, just have the script send a message to a Discord webhook or a hidden admin panel. This lets you see who is potentially cheating without ruining the experience for everyone immediately.
Dealing with Seats and Map Changes
One thing that often breaks a roblox anti teleport script is when the game itself moves the player. For example, if you have a "Teleport to Lobby" button or a car system, your script will think the player is cheating.
To fix this, you should create a global table or a set of attributes on the player. When your game needs to teleport a player legally, set an attribute like Player:SetAttribute("IgnoreAntiCheat", true). Your script can then check this attribute and skip the distance check for a second or two. Just remember to set it back to false once the teleport is finished!
Also, check if the player is in a Seat or VehicleSeat. When a player enters a seat, they become part of that assembly, and physics can get weird. It's usually safer to just disable the check while they're sitting down.
Why Total Prevention is Impossible
I hate to be the bearer of bad news, but you'll never stop 100% of exploiters. It's a game of cat and mouse. You build a better wall, they build a taller ladder. Some exploiters use "tweening" to move just slowly enough that they don't trigger simple scripts. Others might find ways to spoof their state.
The goal of a good roblox anti teleport script isn't to be an impenetrable fortress. It's to make cheating so annoying and difficult that 95% of people don't bother doing it. You want to stop the "script kiddies" who just downloaded a free executor and want to ruin someone's day. The high-level hackers will always find a way, but they are a tiny minority.
Testing Your Script
Once you've written your script, you need to stress test it. Go into Studio, start a local server with two players, and try to break it. * Try lagging yourself: Use a network limiter if you have one. * Try jumping off high places: Does falling at high speeds trigger the kick? (It shouldn't if you're only checking horizontal distance, or if you account for gravity). * Try using legitimate teleports: Does your "Map Vote" system trigger the anti-cheat?
If you can play your game normally for 30 minutes without a single false positive, you're in a good spot.
Final Thoughts
Implementing a roblox anti teleport script is a rite of passage for any serious Roblox dev. It's the moment you stop thinking like a player and start thinking like a system administrator. It takes a bit of fine-tuning to get the balance right between "security" and "player experience," but the result is a much cleaner, more competitive game.
Don't be afraid to tweak your numbers. Every game is different—a high-speed racing game will need a much more relaxed script than a slow-paced horror game. Keep an eye on your server logs, listen to player feedback, and keep refining. Your community will definitely thank you for keeping the teleporting trolls at bay.
