🃏 New Colyseus demo: 𝗧𝘂𝗿𝗻-𝗕𝗮𝘀𝗲𝗱 𝗨𝗡𝗢 A multiplayer UNO card game running on a single authoritative server, with clients built in six different engines - Unity, Godot, Defold, GameMaker, Haxe + Heaps, and React + R3F - all sharing the same backend. A great reference if you're building turn-based or card games with Colyseus. It covers: → Room state & turn order → Deck shuffling and per-client hand sync → Server-authoritative action validation (no cheating your neighbor) → StateView - each player sees only their own hand; opponents expose nothing more than a card count Link to the full source in the comments 👇 #gamedev #multiplayer #Colyseus #Unity #Godot #Defold #GameMaker #indiedev

We built an open-source tank battle demo to show off Colyseus' SDKs and cross-platform capabilities. Unity, Godot, PlayCanvas, GameMaker, Defold, Haxe, Three.js, and Construct 3 — all connected to the same authoritative server, playing together in real time. The server handles physics, collision detection, and state synchronization. Clients just send input and render. Link in the comments.

Raw footage of a work in progress new Instant World using a KitBash3D pack (Elysium). This time we are building a high quality AAA scene running in a regular website 🌐🎯 Original scene is 7M polygons uncompressed with full PBR textures, but still loads fast (<10 sec) and runs in a regular WebGL/WebGPU enabled website even on older Android / Chromebook devices. Live demo link coming soon! Our game engine is running in PlayCanvas, networking powered by Colyseus Multiplayer Framework. Learn more about Instant Worlds and try the original Sandbox demo here: 🔗 http://instantworlds.io #webgl #webgpu #html5 #gamedev #immersiveworlds #metaverse

Multiplay shutting down is another reason to consider owning your servers and infrastructure with free and open-source software.
