Photon2 Unity2D How to send float with RPC

Question

I have big problem in my code .. I want to spawn obstacle exactly on the same position as on the server is spawned so I made rpc Method and tried to pass random variable of float , but when i run the game obstacles are spawned on the diffrent position. I am loosing a lot of time to get it done but I still can not find solution.

Here is the code

   [PunRPC]
    void RPC_SpawnColumn(Vector3 position)
    {
        // Instantiate(prefab, position, Quaternion.identity);
        Debug.Log("THIS IS SPAWNYPOSITION" + spawnYPosition);

        Instantiate(prefab, new Vector2(9, spawnYPosition), Quaternion.identity);

    }

    private void OnTriggerEnter2D(Collider2D collision)
    {
        //print("Are we here");
        if (collision.GetComponent<ColumnsMultiplayer>() != null)
        {
            
            print("Or are we here");
            if (SpawnOnce)
            {
                spawnYPosition = Random.Range(-3.36f, 2.98f);
                
               
               
                photonView.RPC("RPC_SpawnColumn", RpcTarget.Others,new Vector3(9, spawnYPosition));  // this is 
              
            }
                //SpawnColumn();
                
            SpawnOnce = false;


        }
    }

Thank you so much for reading post.

Edit: I need to send spawnYPosition from method two to method one and spawn it with same position of spawnYPosition in the second method.

It looks like you might need a refresher on function arguments.

When you define a function like this:

void RPC_SpawnColumn(Vector3 position)

You're saying "I will accept as input a Vector3 value, and I will call that value position inside the body of this method" - this position variable is called an argument to the function, and you can use it like other variables inside its body.

Now, when you call the function (remotely) like this:

photonView.RPC("RPC_SpawnColumn", RpcTarget.Others, new Vector3(9, spawnYPosition)); 

You're saying "Call the function, and pass it the value (9, spawnYPosition, 0) to use as the position argument"

So, inside the body of RPC_SpawnColumn, if you want the value of spawnYPosition which you passed as the y coordinate of the position argument, you can get it by reading position.y.

So it looks like you want to change this line, which makes up a new vector with whatever value we have in spawnYPosition locally:

Instantiate(prefab, new Vector2(9, spawnYPosition), Quaternion.identity);

to this line, which uses the position that was sent to us via the RPC call (including spawnYPosition in the y component):

Instantiate(prefab, position, Quaternion.identity);
