sending commands from multiple clients

Questions & Answers
1

I’m experimenting with HLAPI and I’m facing a simple problem that doesn’t seem to be handled by any of the functionality provided by the netwoking system.
Let’s say I have a simple cube in the scene that starts moving when any client press a button. It seems that I can send a command to the server from a client if the client has the authority over that object, however this page sates:
http://docs.unity3d.com/ScriptReference/Networking.NetworkIdentity.AssignClientAuthority.html

Only one client can own an object at
any time

Let’s say the players have simply to cooperate based on client inputs of a central copy of the object on the server (the case of the cube), how can one make remote objects receive commands from multiple clients?

code example:

	[Command]
	void CmdToggleMoving(){
		moving = !moving;
		logger.ShowMsg("Moving: " + moving);
	}

	void checkObjectClick(){
		if(Input.GetMouseButtonDown(0)){
			RaycastHit hit;
			Ray ray;
			if(settings.usingVufuia)
				ray = Camera.main.ScreenPointToRay(Input.mousePosition);
			else
				ray = settings.selectedDebugCamera.ScreenPointToRay(Input.mousePosition);
			if(Physics.Raycast(ray, out hit)){
//				Debug.Log("hit something " + hit.transform.name);
				if(hit.transform.name == this.transform.name){
					CmdToggleMoving();
					logger.ShowMsg("Moving: " + moving);
				}
			}

		}

Make several separate invisible objects for each player which they own; make a command on them that moves a cube; now each client sends command to his(her) own object causing cube(same for both) to move.

Add NetworkBehaviour script to player object. This script will contain the command method.
On server it will find the cube (which can be also passed as command argument) and control it.
This way multiple players can move it at the same time.

This will work, because each client is invoking command on the player-owned object (the player).
