Photon Functions

PhotonNetwork.Instantiate

photon instantiate1 is similar to unity initialisation except

  1. It takes a string (e.g., “MyPrefabName”). Place the prefab in Assets > Resources and pass the prefab’s name as the string.
  2. The prefab must have a photon view attached to it.

syntax2: PhotonNetwork.Instantiate(string, location, rotation, custom properties);

PhotonNetwork.Instantiate("MyPrefabName", new Vector3(0, 0, 0), Quaternion.identity, 0);

PunRPC

Some specifications of using RPC:

  1. The function name is passed as a string (e.g., “RPC function”) and the function parameters are passed as variables.
  2. RPC function variables have to be PUN serialisable 3.
  3. The GameObject that the script is attached to must also have a photon view.

syntax4: photonView.RPC("RPC function", RpcTarget.All, [variable1], [variable2]...)

//RPC Fn Call
_photonView.RPC("CreateLineOnAllClients", RpcTarget.All, PhotonNetwork.LocalPlayer.ActorNumber, _currentLineID, localStartPosition);

//Function
private void CreateLineOnAllClients(int actorNumber, int lineID, Vector3 localStartPosition)  
{  
    GameObject newLine = Instantiate(linePrefab, Vector3.zero, Quaternion.identity)
}

The function call can be defined using rpcTarget to specify who will receive the information. RpcTarget.All, RpcTarget.OthersBuffered are used frequently.
