Multiplayer Demo

Get a demo of the Multiplayer feature.

Instructions

Note:
This document aims to provide developers a zero-coding approach to host a multiplayer server with simple management. This document is evolving, and we will strive to keep it consistent with all the eagle specific features we are releasing. We appreciate your patience!

The demo provided is meant to be a starting point. There will be some use cases, however, where the requirements of the UE application will extend beyond the demo Eagle 3D Streaming provides. 

In these cases, Eagle 3D is happy to work under a professional services agreement where we define a scope of work and complete it as per your specifications. We are unable, however, to provide dedicated support for the multiplayer demo to develop additional capabilities.

If our free servers are not online then this demo's multiplayer part might not work. If it does not work then ask support@eagle3dstreaming.com about it or you can request a paid server.

If you would like to demo our multiplayer, follow these steps :

1. First launch this demo in two separate devices (mobile/desktop/….) with an internet connection and browser: https://iframe.eagle3dstreaming.com/

2. Second, walk the character to booth 12 and step on the cylinder protruding from the center of the booth:

If you step into the yellow cylinder you will portal into the multiplayer system demo.

This specific map inspires developers on what can be achieved with Unreal Engine and the Eagle 3d Streaming platform.

1. STARTUP SCREEN

User is presented with a Player Selection screen where the User can select different Avatars and add a Name Tag which is visible above the Player in the multiplayer environment.

2. MULTIPLAYER ENVIRONMENT

Repeat the same process (of going to booth 12 and stepping on the yellow cylinder) from a second device or browser tab and you will see another avatar in the same space.

3. SETUP

Now that you have seen the demo, you can also use Eagle’s Multiplayer Template as a starting point to add Multiplayer into your project using a Dedicated server. In order to do this, you will first need:

Client Build is uploaded to the Eagle Streaming Platform. Client is hardcoded to connect to our machine. This code can be found in Maps/Main map level blueprint of the Eagle 3D Streaming Features Template UE Project (https://bitbucket.org/Eagle3DStreaming/e3dsfeaturestemplate/ )

4. CODE ANALYSIS

First, grab the full source code of the UE4 project from this repository:

Once you host the server, pass the IP address to the Parameters To Pass to App filed(CmdLineParameter field) of your streaming config ( see Image 5 below ) like this:
-dsipaddress=yourIP:Port

(Image 5) below is a screenshot from the Control Panel to show the feature : Parameters To Pass to App where you can pass the IP address .

To get to this feature, you should go to your Control Panel → STEP 2: CONFIG SELECTION → Edit → Developer Options. (Hit Save and Broadcast to apply the instructions to your app).

Here are more information about setting up and creating configs.

The code that will process this value can be found here:

This value (1) is used to generate this (2):

Which produces this window when you step into the yellow portal in map1:

This IP address getting used to connect to the dedicated server pointing by the IP address :

When the stream starts this code the Client will run and connect to STATIC IP ADDRESS mentioned “Server IP”.

Warning 🔧

Cause of the issue :

The Build is not able to connect to the server.

The reasons could be :

1. The dedicated build is not running (follow this document to see how to start a server App)

2. The machine where the dedicated build is running may have some connectivity issues (e.g. firewall permissions, IP address issues, etc.).
   

Issue 2 : ❌ 🚫

After connecting to server, the Camera or pawn get stuck into somewhere (below).

Cause of the issue :

Your game version and Dedicated server version are NOT THE SAME.

Eagle 3D Streaming recommends :

When you Package your game → Package the dedicated server as well and Deploy them and connect them together. (check this document to see how to upload a dedicated server App and start it).
