Metaverse Overview

Overview

This sample demonstrates an approach on how to develop a simple Metaverse.

To do so, the application illustrates several use cases around music, art and games. The player can move from one scene to another at will by using portals. The player has the possibility to enjoy these different spaces with his friends only by setting up a personal group.

Here are the different scenes integrated to this sample:

Avatar selection : the first step is to select an avatar and a nickname.
Hub : this is the player's starting point. This scene is mainly used to navigate to the other spaces.
Picazoo : this scene is a little game consisting in finding and identifying the animals hidden in a park using paint guns.
Music : if you feel like a DJ, this scene is for you !
Art gallery : we illustrate here how to use an API to display artworks dynamically.

Technical Info

This sample uses the Shared Mode topology,
Builds are available for PC, Mac & Meta Quest,
The project has been developed with Unity 2021.3, Fusion 2, Photon Voice 2.53,
2 avatars solutions are supported (home made simple avatars & Ready Player Me avatars),

Before you start

To run the sample :

Create a Fusion AppId in the PhotonEngine Dashboard and paste it into the App Id Fusion field in Real Time Settings (reachable from the Fusion menu).
Create a Voice AppId in the PhotonEngine Dashboard and paste it into the App Id Voice field in Real Time Settings
Then load the AvatarSelection scene and press Play

Handling Input

Desktop

Keyboard

Move : WASD or ZQSD to walk
Rotate : QE or AE to rotate

Mouse

Move : left click with your mouse to display a pointer. You will teleport on any accepted target on release
Rotate : keep the right mouse button pressed and move the mouse to rotate the point of view
Move & rotate : keep both the left and right button pressed to move forward. You can still move the mouse to rotate
Grab : put the mouse over the object and grab it using the left mouse button.

Meta Quest

Teleport : press A, B, X, Y, or any stick to display a pointer. You will teleport on any accepted target on release
Touch (ie for chat bubbles lock buttons) : simply put your hand over a button to toggle it
Grab : first put your hand over the object and grab it using controller grab button

Folder Structure

The main folder /Metaverse contains all elements specific to this sample. There is a sub-folder dedicated to each use case.

The folder /IndustriesComponents contains component shared with the Fusion Stage sample or the Fusion Expo sample.

The /Photon folder contains the Fusion and Photon Voice SDK.

The /Photon/FusionXRShared folder contains the rig and grabbing logic coming from the VR shared sample, creating a FusionXRShared light SDK that can be shared with other projects.

The /Photon/FusionAddons folder contains the Industries Addons used in this sample.

The /XR folder contain configuration files for virtual reality.

Architecture overview

The Metaverse sample rely on the same code base than the one described in the VR Shared page, notably for the rig synchronization.

The grabbing system used here is the alternative "local rig grabbing" implementation described in the VR Shared - Local rig grabbing page.

Aside from this base, the sample uses some Industries addons.

Used Industries Addons

We provide to our Industries Circle members a list of reusable addons to speed up 3D/XR application prototyping. See Industries Addons for more details. Here are the addons we've used in this sample.

Spaces

Spaces addon is used to allow users to switch from a scene to another.

Also, users have the possibility to join the public group or a private group by specyfing a group number. This choice can be made in the avatar selection screen or later with the application menu.

See Space Industries addons for more details.

Dynamic Audio group

We use the dynamic audio group addon to enable users to chat together, while taking into account the distance between users to optimize comfort and bandwidth consumption. So, the networked user prefab (MetaverseNetworkRig) has the DynamicAudioGroupMember class.

See Dynamic Audio group Industries Addons for more details.

Note: if a lot of people gather to a single place, the traffic might reach high numbers anyway: for such need, additional limitations (dynamic proximity distance decreasing with the density, hard limit to the number of followed users, ...) would be relevant.
