Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Roper - Voxel Swing Platformer". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: "Fancade" aesthetic. Use a purely **Voxel/3D Pixel Art style**. All objects (characters, ground, obstacles) should be constructed from combined `THREE.BoxGeometry` primitives to simulate a blocky, low-poly retro look. * **Camera**: Use a **`THREE.OrthographicCamera`** to create a flattened, 2.5D side-scrolling perspective that mimics the provided screenshot while maintaining 3D depth. The camera must smoothly follow the player's X-axis movement with a slight offset to show more of the path ahead. * **Color Palette**: High saturation and contrast. * **Sky**: Solid bright cyan (`#87CEEB`). * **Ground**: Checkerboard pattern of Lime Green and Forest Green cubes. * **Player**: A blocky character composed of pink (body), white (face/hands), and black (hair/shoes) voxels. * **Interactables**: "Swing Points" must be distinct Brown Circles/Spheres suspended in the air. * **Collectibles**: Spinning Gold Coins (yellow voxels). * **Performance (Mobile)**: Merge geometries where possible using `BufferGeometryUtils.mergeBufferGeometries` to reduce draw calls. Use simple Lambert or Phong materials; avoid expensive PBR textures. Shadows should be baked or limited to a single directional light source. ### 2. Audio Requirements * **BGM**: A fast-paced, upbeat **8-bit Chiptune** loop that encourages momentum. * **SFX**: * **Jump**: A short, rising square-wave "blip". * **Swing Attach**: A "zip" or "suction" sound when the rope connects. * **Coin Collect**: A high-pitched "ding" or arpeggio. * **Impact**: A dull thud when hitting a wall/obstacle. * **Fail**: A descending slide whistle or glitch noise when falling off the map. ### 3. Gameplay Loop * **Core Mechanic - Auto-Run**: The character moves automatically to the right (+X axis) at a constant speed. The character **only stops** if they collide with a vertical wall (at which point they turn around or wait for input). * **Action State Machine**: 1. **Running**: Default state on ground. 2. **Jumping**: Triggered by a quick tap. Standard parabolic arc. 3. **Swinging**: The unique mechanic. If the player is airborne and near a "Brown Circle" node, holding the input creates a rope constraint (visualized as a line) between the player and the node. The player then swings like a pendulum. Releasing the input breaks the rope, launching the player based on current momentum. * **Objective**: The player must navigate cliffs and obstacles to collect **100% of the coins** in the level to open the exit or trigger a "Level Complete" state. * **Failure**: Falling off the bottom of the screen (Y < -10) resets the level immediately. ### 4. Mobile Controls & Interaction * **Input Scheme (One-Touch)**: The entire screen functions as a single button to accommodate mobile play without looking at controls. * **Tap**: Jump (if on ground). * **Touch & Hold**: Shoot grappling hook/Swing (if in air and within radius of a Brown Circle). * **Release**: Let go of rope. * **Orientation**: Landscape mode preferred for better forward visibility, but the camera zoom needs to be responsive to screen width. * **Visual Feedback**: * Draw a white line using `THREE.Line` when the rope is active. * Spawn small cubic particle explosions when collecting coins or landing on the ground. * **Haptics**: Trigger `navigator.vibrate(20)` on coin collection and `navigator.vibrate(50)` on death/impact for tactile feedback. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Roper is a captivating retro-style platform game that combines classic pixel art aesthetics with modern physics-based gameplay mechanics. This skill-based arcade adventure challenges players to navigate through 100 unique levels filled with obstacles, cliffs, and coin-collecting challenges.

The game features a distinctive auto-running mechanic where your pixelated character continuously moves forward, only stopping when encountering solid objects or walls. This creates a unique gameplay dynamic that requires precise timing and quick reflexes to master.

Core Features

Retro Pixel Art Design

Roper embraces classic 8-bit aesthetics with charming pixel art graphics that evoke nostalgia for golden-age arcade games. The clean, colorful visuals make gameplay elements easily distinguishable while maintaining that beloved retro charm.

Physics-Based Rope Mechanics

The game's signature feature is its innovative rope swinging system. Players can attach to brown circular platforms and swing across gaps using realistic physics, adding depth and strategy to the traditional platform game formula.

Progressive Difficulty System

With 100 carefully designed levels, Roper offers a perfect difficulty curve. Early stages teach basic mechanics, while later levels introduce complex obstacle combinations that will test even experienced platform game veterans.

Coin Collection Challenge

Each level requires collecting every coin to achieve completion, encouraging thorough exploration and mastery of the game's mechanics. This adds replay value as players strive for perfect runs.

Game Mechanics

Auto-Running System

Your character runs automatically in one direction, creating constant forward momentum. This mechanic transforms traditional platform gaming by removing direct movement control, focusing instead on timing-based interactions.

Jumping and Timing

Success depends entirely on precise timing. Players must judge distances, anticipate obstacles, and execute perfectly timed jumps to maintain progress through increasingly complex level designs.

Rope Swinging Physics

When encountering brown circular platforms, hold the action key to grab and swing. The physics system responds realistically, requiring players to understand momentum and arc trajectories for successful navigation.

Operation Guide

Roper features intuitive one-button controls that are easy to learn but challenging to master:

  • Jump : Press WASD, Spacebar, or Arrow keys to make your character jump
  • Rope Swing : Hold the action key when near brown circular platforms to grab and swing
  • Timing : Release at the optimal moment to maintain forward momentum
  • Obstacle Navigation : Use precise timing to avoid spikes, gaps, and moving hazards

The simple control scheme makes the game accessible to players of all skill levels while allowing for deep mastery through practice and precision.

Why Play This Game

Perfect for Quick Sessions

Roper's level-based structure makes it ideal for both quick gaming sessions and extended play periods. Each level can be completed in under a minute, making it perfect for casual gaming breaks.

Skill Development

The game excellently develops hand-eye coordination, timing precision, and spatial awareness. Players will find their reflexes and judgment improving as they progress through the challenging level progression.

Nostalgic Appeal

Fans of classic arcade and platform games will appreciate Roper's authentic retro aesthetic combined with modern game design principles. It captures the essence of vintage gaming while feeling fresh and engaging.
