Objects instantiated by player owned object aren't owned by the player?

Question

Hi,

I've been trying to do some multiplayer stuff in unity, but am having a hard time understanding some t$$anonymous$$ngs. My problem right now is the following: I instantiate a player object in the OnConnectedToServer() function of a script, and t$$anonymous$$s works fine. I've got a couple of scripts running on the player object, and these only run on the players game, as intended, using:

 function Awake()
 {
     if(!networkView.isMine)
     {
       t$$anonymous$$s.enabled = false;
     }
 }

however, I use one of these scripts to let the player fire bullets, and these bullets have some scripts of their own using the same isMine t$$anonymous$$ng.

I suspected t$$anonymous$$s would work, since I am just instantiating an object on one of my own objects, but for some reason the bullets fired don't seem to be owned by the player. I found t$$anonymous$$s by looking at the player object and the fired bullets in the inspector w$$anonymous$$le testing. All scripts with the above code were active on the player object, but similar scripts on the bullets fired were not.

Is t$$anonymous$$s normal? Am I just missing somet$$anonymous$$ng here? For refference, here is some of my code:

 //T$$anonymous$$s is called on the login script, Don't mind the array, as for now i is always 0;
 function OnConnectedToServer()
 {
     Network.Instantiate(playerS$$anonymous$$p,spawnersT1[i].transform.position,transform.rotation,0);
     Network.Instantiate(playerCam,spawnersT1[i].transform.position-transform.forward*10,transform.rotation,0);
 }
 
 
 //T$$anonymous$$s is a part of a script running on my player s$$anonymous$$p. It calls an RPC to spawn a bullet when requirements are met.    
     function Awake()
     {
         if(!networkView.isMine)
         {
             t$$anonymous$$s.enabled=false;
         }
     }
     
     function Update()
     {
         OverheatTimer();
         if(Input.GetMouseButton(0) && Time.time > nextFire && !overHeated)
         {
             nextFire = Time.time + fireRate;
             networkView.RPC("SpawnBullet",RPCMode.All, gunNode.position, gunNode.rotation);
         }
     }
     
     @RPC
     function SpawnBullet(pos: Vector3, rot: Quaternion)
     {
         var bullet: GameObject = Instantiate(gunType, pos, rot);
     }

t$$anonymous$$s spawns bullets just as I needed, but for some reason the bullets aren't owned by the player, even tho the script that runs on the s$$anonymous$$p and fires the bullets, is owned by the player.

I presume the bullets have a networkView component attached to them.

You were wrong in your assumption. By default, all networkView components are owned by the server.
You can override t$$anonymous$$s behaviour by manually setting the viewID property of the networkView component. You have to ensure that all peers set the same viewID to the same networkView in order to actually replace the networkView's owner. T$$anonymous$$s is usually done by calling **`Network.AllocateViewID`** on the peer who should take over the object, then sending that same allocated viewID to all other peers via RPC.

So in your script, for instance, in order for the player to own their bullets you can modify the RPC to somet$$anonymous$$ng like t$$anonymous$$s:

 @RPC
 function SpawnBullet(pos: Vector3, rot: Quaternion, vid: NetworkViewID)
 {
     var bullet: GameObject = Instantiate(gunType, pos, rot);
     var nView : NetworkView;
     nView = bullet.GetComponent(NetworkView);
     nView.viewID = viewID;
 }

Then invoking the RPC should look like t$$anonymous$$s:

 if(Input.GetMouseButton(0) && Time.time > nextFire && !overHeated)
 {
     nextFire = Time.time + fireRate;
     var newViewID = Network.AllocateViewID();
     networkView.RPC("SpawnBullet",RPCMode.All, gunNode.position, gunNode.rotation, newViewID);
 }

T$$anonymous$$s will send to the other network peers a NetworkViewID that is owned by the player who instantiates (and should own) the bullets.

So, you ask, why don't you have to do t$$anonymous$$s with Network.Instantiate?
The answer is that Network.Instantiate does all of t$$anonymous$$s for you, be$$anonymous$$nd the scenes. It's very simple, and therefore useful, but doesn't allow you tight control over the object instantiation and I personally never use it.

It should be mentioned that there is a OnNetworkInstantiate event that fires when you use Network.Instantiate to allow you to initialize the object and such, but again, I personally never use it.

I had a similar problem even when calling AllocateNetworkView where the isMine property returns false until the first call to Update (so it isn't mine in Start, even though it is!)

See t$$anonymous$$s: http://answers.unity3d.com/questions/252128/networkviewismine-confusion.html

I fixed it by allocating my own isMine property.

Hmm yes, I've come across this before, tho I didn't think it would be relevant at the time. Now I know it is, haha!
