This is not going to work. OnDragBegin will need to check m_isMovingServer. If this has a client network object then it will need to change ownership on the object. Otherwise, you can use an [RPC(SendTo.Everyone)] in order to move the thing

i dont know how to work rpc things

@strange arrow this works but there is a delay on the client side

#

how can i fix it
