You need a server to use Colyseus!

Construct has well-known existing features to “host” a multiplayer session from the frontend. This is not possible when using Colyseus. Colyseus is an authoritative server, written in Node.js. You can’t let your frontend host the game sessions directly.

Example project

Please explore this demonstration project to understand how to use Colyseus with Construct3.

Download .c3p and server files ( View source-code)
Open the RawUsage.c3p file on Construct3 Editor ↗.
Start the local server by running npm install and then npm start on the server folder.

The example project covers the core concepts of using Colyseus with Construct 3:

Joining a Room

Use the “Join Room” action to connect to a room on the server. Once connected, you can listen for incoming messages using “On Message” triggers, and handle disconnection with “On Leave”.

Listening for changes in the State

Use “On State Change” to react whenever the server updates the room state. Access individual state properties using the expression syntax to read synchronized values like scores, positions, or game phase.

Listening for add/remove events on Maps and Arrays within the State

Track when items are added to or removed from collections (Maps and Arrays) in the state. This is essential for handling dynamic lists like players joining/leaving or inventory changes.
