We’re doing it with Final Drop, 100-player open-world battle royale, no install, running in the browser. Still early, but this is absolutely achievable on web: final-drop.com Want easy duos with invite links? Jump in on CrazyGames, game published there too.

1000 bots. One BIG @threejs world. Still 60 FPS. In this test I’m flying over the current world while 1000 bots move around below — with chunk streaming, instanced models, and terrain LOD blending keeping everything smooth in the browser. This is starting to feel real 👀 #threejsJourney #webgl #gamedev #minecraft #threejs

founder of zynga made a browser game engine for 3D today called "Stem Studio" Overview 🔍 • frontend: three.js react typescript • backend: @colyseus to setup multiplayer. Handles server<->client syncing and lobbies/rooms. Written in Typescript/Node.js • Gives you a scene editor right in the browser (like traditional game engines like Unity)! I think this is a first for 3D browser games • No database backend by default, bring your own to persist your game's state Looks like crazy tech tbh, I'll have to give it a try. These opinionated starter repos from the professionals are often much better to start with than prompting base models plain. So if you want to build a 3d browser game with multiplayer, use this: github.com/Stem-Studio/Engin…

RELEASED: Gaussian Splat multiplayer demo is live. Drop into a scanned scene with our Final Drop controller: combat, weapons, bots, friend-vs-friend networking, realtime shadows, and light occlusion. Built with PlayCanvas, link in 🧵

Exploring the all-time classic #prophunt game with @KenneyNL's assets and @colyseus for the multiplayer side. Trying to make an open-source browser version of it with a map editor (see 🧵) #threejs #javascript #indiedev #ScreenshotsSaturday

My latest game project at the moment... using @phaser_ @colyseus and @Zai_org GLM 5.1 here

vibe theft auto is now open source for the #ossvibejam! - complete missions around town for $ - level up your skills - trade stocks - get drunk at the bar - play minigames to make money - win big at the casino - multiplayer pvp - and much more coming soon built with using @colyseus multiplayer server, @threejs, and @codex! shout out to @nicoletteduclar and @wavedash for sponsoring the #vibejam encore!

version 0.18 of @colyseus is probably going to be the last before 1.0 doing so many experiments for 0.18: built-in database tool (@DrizzleORM), admin panel, and built-in prediction tools hopefully after feedback and iteration of what's new in 0.18 we can call it 1.0

Adding multiplayer to Doctrine.shinythings.space took literally 2 minutes. 90 seconds of that was testing it worked between my two rigs once it was pushed to prod. Wild times, and thank you @colyseus

Submitted my game for the #vibejam 🎉 come blast your fellow vibe jammer: Play at vibetheftauto.xyz Your object is simple: go get a pump in the gym. Featuring: - real AI NPCs (go chat with them!) - multiplayer pvp gun fights - missions / tasks It was fun to see what could be built in a couple weeks with AI. And fun seeing what everyone else has built. Built with @threejs @colyseus @ElevenLabs @cursor_ai, codex. Thanks for hosting the vibe jam @levelsio @s13k_ @NicolaManzini !
