How does this cause a NullReferenceException???

Code (CSharp):

1.  [Command]
2.     public void CmdSwap(string net)
3.     {
4.         if(!isServer)
5.         {
6.             return;
7.         }
8.         Player _player;
9.         _player = man.getplayer(net)
10.         Swap swap;
11.         swap = _player.GetComponentInChildren<Swap>();
12.        Debug.log(_player.GetComponentInChildren<Swap>()) //Logs the correct gameobject
13.         if(swap != null) {
14.             swap.RpcSwap();
15.             }
16.     }

Causes "NullReferenceException: Object reference not set to an instance of an object" at swap.RpcSwap().
Also i can call other functions in "swap" just fine.

 

This would happen if .RpcSwap is actually a delegate (function pointer, System.Action, etc.) of some kind and it is still null. Do a:

Code (csharp):

1. Debug.Log( swap.RpcSwap.ToString());

and see what that prints. If it prints something like "method group" then it's valid.

 

Didn't try this but how i fixed it was i created a rpc function in the original script and then transferred everything from the cmd to the rpc and that fixed it.
