Browser Fighting Game
A 2D HTML5 Canvas fighting game with sprite animation loops, hitboxes, collision detection, and 2-player local keyboard controls.
The Prompt
Create a 2D HTML5 Canvas Browser Fighting Game built in TypeScript with modern Canvas API. Build a smooth 60 FPS main game loop using requestAnimationFrame with delta-time calculation to ensure consistent gameplay speed. Implement a modular Fighter class handling sprite sheet animations for idle, forward movement, backward movement, light punch, heavy kick, block, and hit reaction states. Build input controllers supporting two-player local keyboard play (WASD + key strikes for Player 1; Arrow keys + key strikes for Player 2). Implement precise axis-aligned bounding box (AABB) collision detection to evaluate hitboxes intersecting hurtboxes during active attack frames, deducting health points and charging a special attack meter. Include a retro-styled UI overlay displaying dynamic health bars, round countdown timers, special meter gauges, and match outcome announcements with retro sound effects using Howler.js. Design a Character Select screen allowing players to pick between unique fighters with distinct speed, reach, and attack damage attributes.

What's Hard
FAQ
Can AI build Browser Fighting Game?
AI generates initial HTML Canvas boilerplate, UI overlays, and menu screens quickly. Fine-tuning physics loops, frame-data hitboxes, and animation timing requires manual engineering.
How hard is it to build Browser Fighting Game with AI?
It's rated advanced. Very high complexity involving custom requestAnimationFrame execution, delta-time game loops, sprite state machines, and precise collision detection.
What tools do I need to build Browser Fighting Game?
We recommend building it with Base44.
How long does it take to build Browser Fighting Game with AI?
Estimated build time: 8-12 hours.
