Thanks
I solved the problem
I sync with none so when the host object create then same will be created in peer. but the position is not sync
instead, I sync the position with variable posX, posY
now i am able to create multiple instance for host. and also peer can track the position. similar, for peer, I am using the created object under host with peer.id so the game and and game objects are work under the host's hardware. peer only sent input to control his object.
otherwords, peer's data in value is more likewise host's out value is also more.
but the only problem is cheater can easy change the values of a variable when they were a host.
