You could also check by having the server and client cross calculate their movement, and if the server ends up desynched you can move the player to the correct location, however that’s more difficult to achieve without writing a custom humanoid. I’ve tested it out and it works really well and you may be able to take some ideas from this anticheat. Imagine, create, and play together with millions of people across an infinite variety of immersive, user-generated 3D worlds. Here’s a really good anticheat that I’ve seen that simply tries to stop what an exploiter is doing rather than kick or ban them from the game, although it’s experimental. Roblox is ushering in the next generation of entertainment.

Upon determining a player is cheating, it teleports that player back to where they were last time they were … It does this by using a set of “heatsinks”, which quickly gain heat while a player is displaying anomalous behavior, as well as a set of assumptions, such as players only being able to jump a certain height off the ground. I created an experimental anticheat system that heavily curtails common movement cheats like speeding, teleporting, noclipping, flying, and ludicrously-fast spinning. local noclip false game:GetService('RunService').RenderStepped:Connect(function() if noclip then .Humanoid:SetState(11) end end And just change the noclip variable.
