How do I count all the players inside a part?

How do I get a player from a zone?

If you are using an invisible/non-collide brick to define your region, here is a function that can determine if a given Vector3 position is inside of it: function isInsideBrick(position, brick) local v3 = brick.CFrame:PointToObjectSpace(position) return (math.abs(v3.X) <= brick.Size.X / 2) and (math.abs(v3.Y) <= brick.Size.Y / 2) and (math.abs(v3.Z) <= brick.Size.Z / 2) end This should work regardless of the hitbox’s rotation.
