Insantiation problem

Question

Working on trying to get a character model i exported from 3ds max instaniated when a game starts. I been following the PhotonCloud tutorial "Marco Polo", and I can't seem to get it to quite work. Every time this code is called or used (once the game/scene practically starts:

 void OnJoinedRoom(){
         GameObject monster = PhotonNetwork.Instantiate("lawlzy",Vector3.zero, Quaternion.identity,0);
     }

I get this error "Cannot cast from source type to destination type"

Please help.

Doesn't your instantiate have a lot of parameters?

anyways try adding a cast

(GameObject)PhotonNetwork.Instantiate("lawlzy",Vector3.zero, Quaternion.identity,0);

or more info on this:

So I tried the casting method like this:

  void OnJoinedRoom()
     {
         GameObject monster = (GameObject) PhotonNetwork.Instantiate("lawlzy",Vector3.zero, Quaternion.identity,0);
         }

and for a split second, it said "PeerCreated" in the debug area, but nothing spawned and the same error showed up...

I should ask, is the error message actually referring to the line of code you provided? Perhaps something happens when "lawlzy" is instantiated that is throwing an error?

Yes, the error is linked directly to the line of code provided.

To create a prefab, you right click the asset, select prefab, and then move said lawlzy.prefab to a folder called "Resources" in the root project folder, correct?

Code error or seems more likely parameter error?

When you call instantiate, you have to pass the actual object you want to load to the script. Instead of the object, you're passing the name of it.

You need to use Resources.Load("lawlzy") to load the actual object from the resources directory:

   GameObject monster = (GameObject) PhotonNetwork.Instantiate(Resources.Load("lawlzy"), Vector3.zero, Quaternion.identity,0);

Ok so after testing my old code, with your added code:

 GameObject monster = (GameObject) PhotonNetwork.Instantiate(Resources.Load ("lawlzy"), Vector3.zero,Quaternion.identity,0);

I get these errors:

InvalidCastException: Cannot cast from source type to destination type.
Assets/Scripts/Network.cs(24,65): error CS1502: The best overloaded method match for PhotonNetwork.Instantiate(string, UnityEngine.Vector3, UnityEngine.Quaternion, int)' has some invalid arguments 3. Assets/Scripts/Network.cs(24,65): error CS1503: Argument #1' cannot convert UnityEngine.Object' expression to type string'
