In Manual u can read:
[quote:2vabfrve]As synced objects are created, moved and destroyed on the host, they are correspondingly created, moved and destroyed on all connected peers. It is important to disable any behaviors and deactivate any events on the peers that may attempt to move the objects themselves; this will conflict with what Sync object is trying to do, and will not have any effect on the host.
How can i give peer ability to move their own object and sync only with host and other peers (but not them self)?
I enable local input prediction.
Every peer sent positionX and positionY to host, and host set X and Y to sync object but then host send back position of this object back to peer so object dont move smooth.
