  1. Learning coherence

First Steps tutorial

Last updated 1 year ago

The contains a series of small sample scenes, each one demonstrating one or more features of coherence.

If you're a first time user, we suggest to go through the scenes in the established order. They will guide you through some key coherence and networking concepts.

Remember that playing the scenes on your own only shows part of the picture. To fully experience the networked aspects, you have to play in one or more built instances alongside the Unity Editor, and even better - with other people.

Download the Unity project

The Unity project can be downloaded from .

Try a pre-made build

To quickly try a pre-built version of the game, head to and either play the WebGL build directly in the browser, or download one of the available desktop versions.

Share the link with friends and colleagues, and have them join you!

Make your own build

Once you open the project in the Unity Editor, you can build scenes via File > Build Settings, as per usual.

If you want to try all the scenes in one go, keep them all in the build and place SceneSelector as the first one in the list.

If you're working on an individual scene instead, bring that one to the top and deselect the others. The build will be faster.

To be able to connect, you need to also run a local Replication Server, that can be started via coherence > Local Replication Server > Run for Worlds.

You can try running multiple Clients rather than just two, and see how replication works for each of them. You can also have one Client just be the Unity Editor. This allows you to inspect GameObjects while the game runs.

Since you might be building frequently, we recommend making native builds (macOS or Windows) as they are created much faster than WebGL.

You can also upload a build to the cloud and share a link with friends. To do that, or to learn how to host builds on the coherence Cloud.

Don't forget to bring the scene you're interested in to the top, so it is launched automatically.
