Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Eggy Car 3D**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Side-Scroller using **Orthographic Camera**. The aesthetic should be "Low-poly Cartoon," utilizing flat shading and vibrant, saturated colors (Cyan sky, Bright Green grass, Brown dirt). * **The Car:** A low-poly, physics-based vehicle (chassis + 2 independent wheels). It must feature a concave "bed" or "cradle" on top specifically designed to hold a sphere. * **The Egg:** A simple white sphere (or ovoid mesh) with a drawn face texture. It acts as a separate physical RigidBody that rests loosely in the car's cradle. * **Terrain Generation:** Infinite procedural terrain generation (using Perlin noise or combined sine waves) to create increasingly steep hills and dips. The ground mesh must update dynamically as the player moves right. * **Background:** Parallax scrolling layers with stylized mountains, clouds, and palm trees to simulate depth. * **Mobile Optimization:** Use simple geometries (BoxGeometry, CylinderGeometry, SphereGeometry) to keep draw calls low. No complex shadows; use baked ambient lighting or a simple directional light. ### 2. Audio Requirements * **BGM:** A looping, upbeat, whimsical track (whistling or ukulele style) to match the casual tone. * **Sound Effects (SFX):** * **Engine:** Pitch-shifted synth hum that rises with vehicle speed. * **Egg:** A "wobbly" sound when the egg hits the car edges; a "crunch/splat" sound on Game Over. * **Environment:** "Chime" sound for collecting coins. * **UI:** Soft "pop" sounds for button clicks. ### 3. Gameplay Loop * **Physics Engine:** Integrate **Cannon.js** or a similar lightweight physics engine. This is critical. The car needs suspension springs, and the egg must be a free-moving object affected by inertia, gravity, and the car's movement. * **Core Mechanics:** 1. Player accelerates the car to move right. 2. The egg reacts physically to acceleration (rolling back) and braking (rolling forward). 3. **Objective:** Drive as far as possible (Distance = Score). 4. **Fail State:** If the egg falls out of the car and touches the ground, the game ends immediately. * **Collectibles:** Gold coins placed on the terrain (often on hills). Collecting them adds to a currency counter. * **Progression:** The terrain becomes more jagged and slopes become steeper the further the player travels. ### 4. Mobile Controls & Interaction * **Screen Orientation:** Forced **Landscape**. * **Touch Controls (Split Screen):** * **Right Half Screen:** Press and hold to Accelerate (Gas). * **Left Half Screen:** Press and hold to Brake/Reverse. * *Reasoning:* This offers better blind usability than small on-screen buttons. * **UI Layout:** * **Score/Distance:** Large, bold text centered at the top (keep away from notch/corners). * **Game Over Screen:** Large "Restart" button (minimum 60x60px hit area) centered for easy thumb access. * **Feedback:** * **Visual:** The camera should smoothly follow the car with a slight "look ahead" offset. * **Haptic:** Trigger a short vibration (using `navigator.vibrate`) when the egg hits the ground (Game Over) or when collecting a coin. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About Eggy Car

Eggy Car is a uniquely entertaining physics-based casual driving game that combines simple controls with surprisingly challenging gameplay. Your objective is straightforward yet demanding: transport a fragile egg as far as possible without letting it fall from your car and crack. This deceptively simple concept creates an addictive gaming experience that tests your patience, timing, and driving finesse.

The game features bright, colorful cartoon graphics with a cheerful atmosphere that makes even the most frustrating egg-drops feel lighthearted. With its endless gameplay mode, you'll always be chasing your personal best distance while unlocking new vehicles along the way.

Core Features

Physics-Based Challenge

The heart of Eggy Car lies in its realistic physics engine. The egg bounces, wobbles, and reacts naturally to every movement of your car. This creates an authentic challenge where every acceleration, brake, and turn matters. The physics feel genuine without being overly complex, making the game accessible yet rewarding to master.

Endless Progression System

Unlike traditional level-based games, Eggy Car offers an endless driving experience. There are no checkpoints or time limits - just you, your car, and the open road ahead. This design keeps the gameplay fresh as the terrain becomes increasingly challenging the further you travel, with steeper hills and more unpredictable bumps testing your skills.

Vehicle Upgrade System

Collect coins scattered along the road to unlock new vehicles, each offering different handling characteristics. Lighter cars provide speed but require more precise control, while heavier vehicles offer stability at the cost of agility. This variety ensures that players can find a driving style that suits their preferences and skill level.

Strategic Power-ups

The game includes helpful power-ups like the Freeze ability, which locks your egg in place during particularly challenging sections, and Magnets that automatically collect coins so you can focus entirely on driving. These additions add strategic depth without overwhelming the core gameplay.

Gameplay Mechanics

The fundamental challenge of Eggy Car revolves around finding the perfect balance between speed and caution. You'll start at the base of a hill with your egg precariously positioned in the car, ready to tumble at the slightest misstep.

Mastering the Hills

Climbing hills requires gentle acceleration - too aggressive, and your egg will bounce right out. As you crest each peak, you must ease off the accelerator and prepare for the descent, where careful braking prevents the egg from sliding forward while avoiding excessive bouncing.

Coin Collection Strategy

Gold coins are strategically placed throughout the course, often in tempting but dangerous positions. Smart players learn to evaluate risk versus reward, collecting coins only when safe to do so. The automatic coin collection from Magnet power-ups eliminates this dilemma during crucial driving moments.

Operation Guide

Eggy Car uses minimal controls that anyone can learn in seconds:

  • A Key or Left Arrow : Move backward/brake
  • D Key or Right Arrow : Move forward/accelerate
  • Mouse : Navigate menus and select upgrades

The key to success lies not in memorizing complex controls, but in developing a feel for the physics. Smooth, gentle inputs work better than aggressive movements. Many players find success in developing a rhythm: accelerate on climbs, ease off at peaks, and brake gently on descents.

Pro Tips for Success

  • Practice Patience : Rushing leads to cracked eggs. Steady, controlled driving wins the distance race
  • Use Gravity : Let hills help you maintain speed rather than fighting them with excessive acceleration
  • Master the Reverse Tap : Quick backward taps can save a sliding egg and stabilize your car
  • Focus on the Road : Don't get distracted by coins if they require risky maneuvers

Why Play Eggy Car

Eggy Car offers a perfect blend of accessibility and challenge that appeals to both casual players and gaming enthusiasts. The game's charm lies in its ability to be immediately understandable yet continuously engaging. Each attempt teaches you something new about the physics and optimal driving techniques.

The cheerful visual style and upbeat soundtrack create a positive gaming atmosphere that makes even failures enjoyable. The egg character's expressive face adds personality to the experience, making you genuinely care about keeping it safe.

For players seeking a quick gaming session, Eggy Car delivers immediate fun without requiring long-term commitment. For those wanting to master the challenge, the endless gameplay and upgrade system provide substantial replay value. The game perfectly balances frustration and reward, ensuring that each successful run feels genuinely earned.
