《Crush》产品需求文档 (PRD)

1. 游戏概述 (Game Overview)

• 游戏名称: Crush
• 元描述: "Crush" is a sandbox game where players control a camera over a vast asphalt plane. The game focuses on exploration and interaction with the environment through dynamic camera movements.

• Explore a 1000x1000 pixelated asphalt ground plane with intuitive drag, scroll, and multi-touch camera controls. • Dynamic key lighting casts realistic shadows, enhancing the visual experience of the blocky, Minecraft-style world.

• 屏幕方向: 横屏 (Landscape)
• 适配平台: PC网页端 / H5移动端

2. 核心功能与系统设计 (Core Features & Design)

以下是根据 AI 对话创作历史整理的核心系统模块：

• 核心机制: Hey there! What kind of game do you want to create?
• 核心机制: I've created Crush - your pixelated asphalt sandbox! You've got a massive 1000x1000 blocky plane with dynamic shadows and full camera freedom. Drag to pan across the surface, scroll to zoom in and out, and use two fingers to rotate your view (or right-click drag on desktop).
• 核心机制: Done! I've stripped away all the UI clutter—no more mode indicator, help button, menu button, or controls drawer. Now you've got a pure, clean 3D viewport with just the canvas. Your camera controls are still fully functional, and you can still access settings in Edit mode. Perfect blank canvas for adding gameplay! 🎮
• 核心机制: No, there's no "unit" variable in the game currently. The game uses raw numeric values for distances (like cameraDistance), angles (like cameraAzimuth), and positions. Were you thinking of adding a unit system for scaling or measurements?
• 核心机制: Done! I've added a unit system where 1 unit = 2.5 pixels. You can now reference window.gameConfig.unit whenever you need consistent scaling for objects and measurements throughout the game.
• 核心机制: Your curb grid is ready! I've added a 4×4 array of flat concrete cuboids (36×36 units each, 0.6 units tall) spaced 24 units apart and perfectly centered on the ground plane. Each curb has a pixelated concrete texture tiled 4×4 for that authentic Minecraft look, and they all cast and receive shadows from your key light. Zoom in and pan around to see them! 🏗️
• 核心机制: Your curb grid now covers the entire 1000×1000 ground plane! The concrete pattern tiles seamlessly across the whole map, giving you a massive pixelated surface to explore. 🎮
• 核心机制: Your concrete texture is getting a makeover! I've started generating a new version with a more neutral grey tone and visible cracks running through it for that weathered, realistic look. The texture will tile perfectly across all your curbs. 🏗️
• 核心机制: Your concrete texture is getting that perfect 808080 grey tone with visible cracks! The new texture is generating now and will tile beautifully across all your curbs. 🏗️
• 核心机制: Your concrete texture is now getting a pavement makeover! I've started generating a new version with that weathered asphalt look while keeping the cracks and grey tone. Your curbs will look like a proper road surface once it's ready! 🛣️
