How do I change a Vector3 Value??

(only first 8 lines) c = game.Players:GetChildren() x,y,z = script.TargetPosition.Value.X ,script.TargetPosition.Value.Y, script.TargetPosition.Value.Z while wait() do for i = 1, #c do local points = ``game.ReplicatedStorage.RemoteFunction:InvokeServer(c[i].Character.Torso.Position) x,y,z = points.X, points.Y, points.Z

it doesn't change the value

To make a Vector3 from three coordinates, you use Vector3.new(x, y, z).

For example,

Brick.Position = Vector3.new( vec.X, vec.Y, vec.Z )

However this is redundant. There's no need to construct a value when you already have one:

Brick.Position = vec

Rarely is it that you will need to deconstruct a Vector3 into its coordinates; it's just unnecessary. Using it as a single Vector3 is less typing, faster, and easier.

I don't really understand what it is you are trying to do here, so I can't give any more specific advice.

I also see you are using a remote function you've just named RemoteFunction. That's a useless name -- it should describe what it does so that your code is more explanatory and descriptive.
