VoxelCraft Online

Okay, let's outline the plan and start with the basic structure for your web-based voxel game. **Game Design and Implementation Plan** * **Game Title:** VoxelCraft Online * **Core Features:** * Infinite Voxel World: Procedurally generated terrain. * Block Building/Destruction: Place and remove various block types. * Crafting System: Combine resources to create tools and items. * Survival Mode: Manage health, hunger, and resources; face environmental challenges and mobs. * Creative Mode: Unlimited resources, flight, instant block breaking. * Inventory System: Manage collected items and equipped gear. * **Target Platform:** Web Browser (Desktop focus initially). No downloads or installations required. Runs directly via HTML5, JavaScript, and WebGL. * **Additional Features:** * Biomes: Diverse environments (forests, deserts, mountains, etc.) with unique resources and characteristics. * Mobs: Passive (animals) and Hostile (monsters) creatures with basic AI. * Tools and Armor: Different tiers affecting mining speed, damage, and protection. * Day/Night Cycle: Affects lighting and mob spawning. * Basic Physics: Gravity for specific blocks (sand, gravel) and player/mob movement. * Multiplayer Mode: (Future Goal) Allow multiple players to interact in the same world via WebSockets. * **Development Tools and Languages:** * HTML5: Structure of the game page. * CSS: Styling for UI elements (inventory, menus, HUD). * JavaScript (ES6+): Core game logic, interactions, state management. * WebGL (via Three.js): 3D rendering of the voxel world, player, and mobs. * Web Workers: Offload heavy tasks like chunk generation/meshing to prevent freezing the main thread. Let's begin by setting up the basic HTML structure, CSS for styling, and the main JavaScript file using Three.js for rendering. VoxelCraft Online

Click the screen to lock the pointer. The next steps would involve replacing the ground plane with actual voxel chunks and implementing block placement/destruction.
