Basic Anti-Speed Script

This is a simple serverside anti speed script which scales with walkspeed.

I recommend using CloneTrooper1019’s FastWait module for better accuracy.

How to make Anti-Teleport Hack?
#2

If the player starts falling then this script will break(false-positive).

Would you mind expanding on that? Because I don’t see it.

#4

The player falls at a higher speed than what the script expects, so the script will detect that the player is moving very fast, therefore giving a false-positive(false-positives are just things that were thought to be correct but wasn’t).

#5

I don’t see anything in the script which would pick up a change in height of the player.

My bad, didn’t notice that.

#7

The script does not take vertical position into account therefore it will not cause a false positive.

Sorry to revive this topic. Where should i place this script? I assume ServerScriptService? And would this affect a monster npc that walks around with an AI script? Thanks!

No it wouldn’t lol, it’s only checking real players and real humanoids, the game.Players.PlayerAdded event only fires for players, and I doubt the npc uses walk speed, most of them use cframe, vector movement.
