coherence / first-steps-tutorial

A tutorial to take your first steps with coherence, a Unity networking framework.

Welcome! This is a tutorial project to take your first steps in coherence, a framework for networking in Unity.

First Steps contains a collection of small scenes, each one demonstrating one or more features of coherence.
After downloading this Unity project, we suggest to open up the documentation as it's the perfect companion to explore the scenes included in the project.

Topics covered

• Basic syncing of variables
• Messaging with Network Commands (RPCs)
• Networking animation
• Networking complex hierarchies
• Spatial queries and optimisation
• Using persistent world data

Unity version

Currently the project is on Unity 2021.3.27f1. You can open it with newer 2021.3 LTS patches or with 2022.3 LTS.
Opening the project with Unity 2022.1 or 2022.2 is discouraged, due to a Unity bug. The bug was fixed in 2022.3 LTS.

Additional resources

Direct download

You can download the project using the Code button on this repo, as this project doesn't require LFS Support. Or fetch a release from the Releases page.

Documentation

Full documentation for this project is available as part of the coherence documentation.

Trying a pre-made build

Check out the game on the coherence Cloud and either play the WebGL version of the game directly in your browser, or download one of the available desktop versions.

(note: we recommend Chrome, other browsers can have problems with Unity’s WebGL)

Animation state mismatch in 2_Physics scene

In the 2_Physics scene, when a player steals the box from another, the original player with authority remains in the animation as if they are still carrying the box.
