How do you update an input field text component that can be edited by two players?

dwalch

I am trying to use OnPhotonSerializeView() or RPCs to update the text that is entered into a UI Input field. These input fields will be instantiated into the game as scene objects and will be able to be edited by either player. I am having difficulty finding resources on how to do this well. All input would be really appreciated! Thanks!

Hi @dwalch,

since you are instantiating this UI element as a scene object, it already has a PhotonView component, which means that you can use RPCs on this object. To use a RPC, you need a reference to the PhotonView component which you can get by using GetComponent<PhotonView>(). On this component you can use the RPC function and add the text from the UI element as parameter, e.g.: photonView.RPC("UpdateText", PhotonTargets.All, text);. Next you'll need a receiving function which is tagged with the [PunRPC] attribute, e.g.:

[PunRPC]
public void UpdateText(string text) { }

Inside this function you have to update the text of the UI element, e.g.: uiElementReference.text = text;.

You know when to fire a RPC by using the EndEdit event. Don't use the OnValueChanged event in this case. Please check the Unity Scripting API for more information about the Input Field.

Hi @Christian_Simon

Thank you so much for your response! You have been really helpful. I apologize if this is an easy question, but I am confused on where you are getting the "uiElementReference"?

This is the script that I currently have. Would you mind taking .a look at it and seeing what I can change to it? Thanks, man!

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class UpdateInput : Photon.PunBehaviour
{
    public InputField text;

    private void Update()
    {
        GetComponent<PhotonView>();
        photonView.RPC("UpdateText", PhotonTargets.All, text);
    }


    [PunRPC]
    public void UpdateText(string text)
    {
        uiElementReference.text = text;
    }
}

Hi @dwalch

@Christian_Simon just meant that as an example in your case it'd be text.text since you named your input field variable text.
