Private Schema variable? inside Player instead of State Schema?

export class Player extends Schema {
@type("number")
x = Math.floor(Math.random() * 400);
@type("number")
y = Math.floor(Math.random() * 400);
@type("number")
cx = 0;
@type("number")
cy = 0;
}

export class State extends Schema {
@type({
map: Player
})
players = new MapSchema < Player > ();

}

i want some of my variables not sent over client inisde player schema

it seams remove @type("number") to some variable makes it private over the network
