onDisconnectDone - Can only be called from the main thread...

Question

I can not call methods (for example SendMessage) from onDisconnectDone. I always get an exception like this: Can only be called from the main thread ... There is no such problem on onConnectDone. A small sample code (Unity 2017.4.0f1):

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using com.shephertz.app42.gaming.multiplayer.client;
using com.shephertz.app42.gaming.multiplayer.client.events;
using com.shephertz.app42.gaming.multiplayer.client.command;
using com.shephertz.app42.gaming.multiplayer.client.listener;

public class WarpTest : MonoBehaviour, ConnectionRequestListener
{

	public string apiKey = "<apiKey>";
	public string pvtKey = "<pvtKey>";

	void OnWarpConnect ()
	{
		print ("Warp Connect!");
	}

	void OnWarpDisconnect ()
	{
		print ("Warp Disconnect!");
	}
	
	public void onConnectDone (ConnectEvent eventObj) 
	{
		this.SendMessage ("OnWarpConnect", null, SendMessageOptions.DontRequireReceiver);
	}

	public void onDisconnectDone (ConnectEvent eventObj)
	{
		this.SendMessage ("OnWarpDisconnect", null, SendMessageOptions.DontRequireReceiver);
		// ERROR!
	}

	public void onInitUDPDone (byte resultCode) { }

	// Use this for initialization
	void Awake () {
		WarpClient.initialize (this.apiKey, this.pvtKey);
		WarpClient.GetInstance ().AddConnectionRequestListener (this);
	}
	
	// Update is called once per frame
	void Update () {
		if (Input.GetKeyDown (KeyCode.C)) WarpClient.GetInstance ().Connect ("Player");
		if (Input.GetKeyDown (KeyCode.D)) WarpClient.GetInstance ().Disconnect ();
	}
}

I have forwarded this to my development team to look into it. I will update you as soon as possible.

Good. Thank you! I will wait.

Hi,

You need to call sendMessage on main thread as onDisconnectDone is not fired on main thread.

Let me know if you have any further query, I will be happy to help.

Thanks.

Thank you. I decided to use the events. Now there are no exceptions.
