Spiderman 3D Swing

Swing through Manhattan, do cool tricks, and explore the city as Spider-Man in a fun 3D adventure.

Inspiration

I wanted to recreate the feeling of being Spider-Man by swinging between skyscrapers, building momentum, and moving freely through a city.

What It Does

Spider-Man: 3D Swing is a browser-based 3D web-swinging game set in a Manhattan-inspired city.

Players can attach webs to buildings, swing through the skyline, steer in mid-air, use Web-Zip, perform air tricks, and activate the four-web Slingshot Catapult. The game also includes score combos, multiple suits, different environments, sound effects, and an interactive cinematic sequence.

Special Tip: There is a custom cinematic cutscene you can try out! Press the 'T' key during gameplay to give it a go.

How I Built It

I built the game using React, TypeScript, Vite, and Three.js.

I created a custom game engine from scratch to handle the physics of web swinging, player movement, dynamic camera controls, visual effects, audio, procedural city generation, and the React HUD interface.

Challenges I Ran Into

  • Responsive Physics: Making the web swinging feel fluid, responsive, and enjoyable instead of rigid.
  • Synchronization: Perfectly synchronizing the player, camera, web anchors, and physics calculation loop in real-time.
  • Cinematics: Creating and animating a multi-character cinematic sequence with three Spider-Man variants in a 3D space.
  • Web Optimization: Maintaining smooth, lag-free performance (60 FPS) inside a standard web browser.

Accomplishments That I'm Proud Of

  • Creating a fully playable 3D web-swinging system completely from scratch without external physics engines.
  • Implementing advanced movement mechanics: Web-Zip, air tricks, score combos, and the Slingshot Catapult.
  • Designing a cinematic sequence featuring three Spider-Man variants.
  • Building a real-time HUD that tracks speed, altitude, score, and movement status dynamically.
  • Successfully deploying the game online with zero friction for the players.

What I Learned

I learned how physics, camera movement, animation, sound, and visual effects work together to create a satisfying game feel (juice). I also mastered the integration of a real-time Three.js game loop with a React-based UI state management.

What's Next for Spider-Man 3D Swing

  • Add more famous city landmarks.
  • Add time-attack challenges and checkpoints.
  • Implement a global leaderboard support.
  • Improve controller and mobile touch support.
  • Add more web abilities and acrobatic tricks.
  • Further optimize performance and visual assets.
