Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Jonny Backflip: Mobile Remake". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: A "2.5D" side-scrolling aesthetic using an **OrthographicCamera** to mimic the original cartoon look but with 3D depth. Use **Low-Poly models** with a **Toon Shader (Cel-shading)** to replicate the flat vector art style of the screenshot while ensuring high performance on mobile devices. * **Key Assets**: * **The Rider**: A stylized motocross rider with a slightly oversized helmet (chibi proportions) to make orientation visible on small screens. The rider must be a separate mesh from the bike to allow for "ragdoll" effects upon crashing. * **The Bike**: A red dirtbike with distinct wheels that have independent suspension animations. * **The Track**: Procedurally generated terrain chunks (hills, ramps, flat landings) using a Catmull-Rom spline or simple heightmap. The ground should be grey/brown, distinct from the background. * **Background**: Parallax scrolling layers. Layer 1: Green rolling hills (closest). Layer 2: Silhouette of trees/mountains (distant). Layer 3: Gradient skybox (Yellow to Blue). * **Performance**: Use a single directional light with soft shadows. Bake static lighting where possible. Limit distinct draw calls by merging terrain geometries. ### 2. Audio Requirements * **BGM**: High-energy **Pop-Punk or Skate Rock** track (fast tempo, distorted guitars) to match the "extreme sports" vibe. * **Sound Effects (SFX)**: * **Engine**: A looped engine rev sound that modifies its pitch based on the bike's velocity. * **Suspension**: A "squeak/crunch" sound when landing hard. * **Stunts**: A "Whoosh" sound when rotating in the air. * **Crowd**: Cheering sound effect when a backflip is successfully landed. * **Crash**: A comedic "bonk" or bone-crunch sound when the player hits their head. ### 3. Gameplay Loop * **Core Mechanics**: Physics-based side-scrolling motorcycle riding. The player accelerates right, launches off hills, and must balance the bike in mid-air. * **Objective**: Travel as far as possible without crashing. Performing backflips and frontflips replenishes "Nitro" or gives score multipliers. * **Physics Logic**: * **Ground**: `Up` arrow accelerates, `Down` arrow brakes/reverses. * **Air**: The bike rotates around its center of mass. Holding `Left` leans back (Backflip), holding `Right` leans forward (Frontflip). * **Landing**: Landing parallel to the ground maintains speed. Landing perpendicular or upside-down triggers a "Wasted" fail state. * **Upgrade System (Simplified)**: Collect coins scattered on the track to upgrade Max Speed, Rotation Speed, and Shock Absorption between runs. ### 4. Mobile Controls & Interaction * **Screen Orientation**: **Landscape** mode locked. * **Touch Controls (Split Screen)**: * **Right Screen Half**: Hold to **Accelerate** (Gas). * **Left Screen Half**: Hold to **Brake/Reverse**. * **Air Controls**: When the bike is not touching the ground: * Tap Left side of screen: Rotate Counter-Clockwise (Backflip). * Tap Right side of screen: Rotate Clockwise (Frontflip). * **UI Layout**: * Large, semi-transparent virtual buttons (min 60x60px) in the bottom corners for visual feedback of inputs. * **HUD**: Speedometer and Score anchored to the top-left. "Nitro/Boost" bar anchored to the top-right. * **Feedback**: Trigger `navigator.vibrate(50)` on successful landings and `navigator.vibrate(200)` on crashes. Add a "Camera Shake" effect on impact. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Operation Guide

Movement Controls: - Use arrow keys or WASD to control bike acceleration, braking, and balance - Manage your rider's weight distribution during jumps for optimal landing - Time your tricks carefully - too much rotation can lead to crashes

Stunt Execution: - Build speed approaching ramps for maximum air time - Initiate tricks during flight phase for maximum point scoring - Focus on clean landings to maintain momentum and avoid crashes

Strategy Tips: - Start with simpler tricks and gradually progress to more complex combinations - Observe track layouts to identify optimal stunt opportunities - Balance speed with control - excessive speed can make landings more difficult
