Disallowed movement

[NiLSPACE]

Hello and welcome to the forum

If you want to stop a player from moving you have to return true, not false.

Also, the NewPosition is a Vector3d variable. What you could do is use this:

if (NewPosition:Equals(Vector3d(-370, 219, 131))) then
   return true
end

Also notice the "end" to mark the end of the if block.
