5.2.1p3 SpawnWithClientAuthority and ReplacePlayerForConnection Crash Unity (windows 7)

on a player object spawned by the networkmanager or from the derived networkmanager (I tried doing it from both classes), I call a CmdSpawnPlayer that I want to spawn a different, new object for the player.

I've tried SpawnWithClientAuthority (wanting the player to control the two objects) --didn't work and tried ReplacePlayerForConnection thinking maybe there was some issue with the client only being able to control 1 object (though I thought it should be able to have authority over more than 1.

Both crash unity to the desktop using the only minor tweaks from the sample in the docs...

Am I missing something or is this a bug with patch (Access Violation)? Obviously Unity shouldn't crash to the desktop even if I made a mistake, but am I approaching the problem correctly? What else can I try?

Thanks....

public class Player:NetworkBehaviour{
...

void SpawnPlayerObject()
{
if(isLocalPlayer)
{
CmdSpawnPlayerObject(playerObjectPrefab)
}
}

[Command]
void CmdSpawnPlayerObject(GameObject playerObject)
{
//playerObject is a prefab with a NetworkIdentity with "localAuthority" and the item is registered with the NetworkManger in the editor

GameObject go =Instantiate (playerObject);

NetworkServer.SpawnWithClientAuthority(go, connectionToClient);//debuggin shows this line always crashes Unity.. connectionToClient="hostId: -1 connectionId: -1 isReady: True channel count: 0"...go is a non-null valid object
}

}

 

Thanks for the response. This is driving me nuts, so I am appreciative of any help.


I was following the code in VS debugger, so seems like a misunderstanding somewhere (not sure why you are saying the playerObject will be null)
VS debugger:The GameObject "playerObject" is not null in the Cmd function. The GameObject "go" is also not null after the Instantiate, when I call the SpawnWIthClientAuthority. I thought it would have to do with the hostId=-1 and/or connectionId=-1...seems like those should be non -1 integers for a valid value.


I've been trying this in a hosted network...so maybe on a remote->server cmd you can't pass a gameObjectPrefab? However, see below....

Think player pet. What I want is the player to tell the server to spawn a 'pet' that the player will also have control of. I've also tried using a GameObject property directly in the player class instead of passing it in through the Cmd function. It again creates a valid GameObject in the Instantiate function, but then continues to crash Unity with the SpawnWithClientAuthority.

 

If I simply NetworkServer.Spawn(go); Unity locks up (doesn't crash, locks up. unresponsive). I've tried submitting a bug through FogBugz system, but it never showed up. 5.2.1f had a lot of issues with the HL networking that I was running into, but not like this. I am sure this has to be a Unity bug and will get fixed as long as someone there knows about it.

 

Ok, so I stripped down the object I was trying to instantiate to nothing but an empty gameobject and it spawned without crashing. I added one component back at a time to rebuild the prefab into exactly what I had before and it will spawn without crashing or locking up now...so I would guess the prefab data was corrupt or something.

It doesn't seem to be spawned with clientauthority however. But that is likely in need of a new thread.
