Creating Games

VULK generates fully playable browser games — from 2D dungeon crawlers to 3D open-world driving games.

Game Types

VULK automatically detects which type to generate based on your prompt.

2D Canvas Games

Tile-based games rendered on HTML5 Canvas with procedural generation.

"Create a dungeon crawler RPG with multiple floors, enemies, and loot"

This generates:

• Procedural maps — different layout every playthrough
• Turn-based combat — bump into enemies to attack
• Player progression — HP, XP, attack, defense stats
• Multiple floors — descend deeper for harder enemies
• HUD — health, score, and floor displayed on canvas

Controls

• Desktop — WASD or arrow keys to move
• Mobile — Swipe gestures for direction

Prompt Examples

"Create a roguelike dungeon crawler with potions, traps, and a boss on floor 5"

"Create a pixel-art top-down RPG with an overworld, towns, and random encounters"

"Create a Zelda-style adventure game with keys, locked doors, and treasure"

3D Physics Games

3D games using Three.js for rendering and Cannon.js for realistic physics.

"Create a 3D racing game with a track, jumps, and boost pads"

This generates:

• Physics engine — realistic collisions, gravity, and friction
• Vehicle controls — acceleration, steering, braking
• Camera system — third-person follow camera
• HUD overlay — speed, score, lap counter

Prompt Examples

"Create a 3D platformer with jumping, moving platforms, and collectible coins"

"Create an arcade space shooter with asteroids, power-ups, and a boss fight"

"Create a bowling game with realistic pin physics"

Advanced 3D Games

Large-scale 3D games with procedural worlds, traffic systems, and day/night cycles.

"Create a GTA-style driving game with a procedural city, traffic, and day/night cycle"

This generates:

• Procedural city — buildings, roads, and intersections
• Traffic AI — cars driving on roads with collision avoidance
• Day/night cycle — dynamic lighting and sky color changes
• Vehicle physics — suspension, steering, acceleration
• Third-person camera — smooth follow with rotation

Prompt Examples

"Create an open-world driving game with a city, highway, and countryside"

"Create a flight simulator with terrain, buildings, and cockpit instruments"

"Create a 3D survival game with crafting, enemies, and a day/night cycle"

Game Architecture

All VULK games use a state machine pattern instead of page routing:

Menu → Playing → Game Over
              → Victory

The game loop runs inside a single requestAnimationFrame cycle — React handles only the menu screens and HUD overlay, while the game engine handles all gameplay rendering and logic.

Tips

• Be specific about mechanics — "bump combat with XP system" produces better results than just "RPG"
• Mention the genre — keywords like "roguelike", "platformer", or "racing" activate specialized generation
• Describe the win condition — "defeat the boss on floor 10" or "complete 3 laps"
• Request specific features — "power-ups", "inventory", "minimap", "leaderboard"
• Keep scope realistic — a focused game with polished mechanics beats an ambitious one that breaks

Limitations

• Games run in the browser — performance depends on device hardware
• 3D games require WebGL support (most modern browsers)
• Multiplayer is not supported (single-player only)
• No asset imports — games use procedural graphics, shapes, and emoji sprites
• Complex games may need follow-up edits to fine-tune mechanics
