What？

You need to add net body and net identity components to the moving object, otherwise only the host is able to interact with it properly.

thx, but i have a new one question, do you know how to add music in a level?

Import the music in mp3 or ogg format and add Audio Source component to the game object you want, then in audio source select or drag the imported file in AudioClip, select Effects or Music in Output. After that you edit what you want, things like play on awake, loop, volume, distance and spatial blend (change this to 3d if you want the music to be in a specific area).
