This Repo contains samples that demonstrates how to enable Local Multiplayer in Mixed Reailty using Unity
If you are using Meta XR Core SDK v65+ and (Netcode for GameObjects or Photon Fusion 2) the majority of this code has been ported over to Multiplayer Building Blocks which provides a simpler version of this repo that demonstrates how to enable Mixed Reality Local Multiplayer
The sample contains 3 different Unity Projects. Where each project contains one of the following Networking Layers
- Netcode for GameObjects
- Photon Fusion 1
- Photon Unity Networking 2
In each Unity Project, the Multiplayer Sample contains the following
- Matchmaking - Finding Players to play with
- Player Connection - Players joining the same game to play in
- Colocation - Players can see the same object in the same position
colocation-package - Contains network agnostic interfaces that can be used to implement colocation
colocation-sample-fusion - Contains a Local Multiplayer Sample using Photon Fusion 1 as the networking layer
colocation-sample-ngo - Contains a Local Multiplayer Sample using Netcode for GameObjcts as the networking layer
colocation-sample-pun2 - Contains a Local Multiplayer Sample using Photon Unity Networking 2 as the networking layer
This codebase is available as both a sample and a template for mixed reality projects. The majority of the project is licensed under MIT LICENSE, however files from Text Mesh Pro, and Photon SDK[1] [2], are licensed under their respective licensing terms.
