I want to make proper Anti-cheat, so I made a script that checks the position of characters.
But I noticed its problem even if it has low pings, Character position lagging between Server and Client is too high before few days.
Like this:

The difference is almost 3~4 studs.
and i made this script to security my game:
![]()
The hitbox isn’t too precise.
(It’s same in the ROBLOX)
How to fix it safely against hacking?
