High-Performance Browser FPS Multiplayer
A fast-paced, competitive first-person shooter (FPS) designed for browser environments. It features advanced movement mechanics, skill-based gunplay, real 3D models, and a robust real-time multiplayer backend.
- 3D Engine: Three.js (Optimized for 60+ FPS across devices).
- UI Framework: HTML5/CSS3 with Vanilla JS (Premium glassmorphic aesthetic).
- Physics: Cannon-es / lightweight custom AABB collision to ensure smooth, high-framerate performance on low-end devices.
- Asset Pipeline:
- Using strictly Real 3D Models (GLTF/GLB formats).
- High-quality models for weapons, characters, and maps sourced from reliable CDNs.
- Framework: Node.js with Express.
- Networking: Socket.io for low-latency, real-time multiplayer synchronization.
- Server Authority: The server validates movement and hit detection to prevent cheating, utilizing client-side prediction for lag-free gameplay.
To guarantee a steady 60 FPS and cross-device compatibility:
- Asset Optimization: Compressed textures, LOD (Level of Detail) models.
- Rendering: Frustum culling, InstancedMeshes for repeated objects (bullets, environmental props).
- Tick Rate: Server runs at a steady 20-30 ticks per second; the client interpolates positions to render smoothly at 60+ FPS.
- Set up Node.js server with Socket.io.
- Establish the client-server connection.
- Synchronize basic player positions and states across the network.
- Load a real
.glbcharacter model. - Load real
.glbweapon models. - Set up a visually stunning map (cyberpunk/neon arena style).
- Implement First-Person camera logic attached to the 3D model.
- Advanced Movement: Sprinting, sliding, jumping, and crouch mechanics.
- Shooting Logic: Raycasting from the camera center, server-validated hit detection.
- Recoil, bullet spread, and weapon firing animations.
- Connect the massive HTML/CSS UI to the game engine.
- Implement Health/Damage systems, Kill Feed, and Scoreboard.
- Create game modes (Deathmatch, Team Deathmatch).
- Build the client:
npm run build- Start the multiplayer server:
npm run server- Open your browser to:
http://localhost:3000
