Prompt

MODEL: Seele01-Flash
Based on the visual analysis of the screenshot and the provided game description, here is the detailed prompt designed to guide an AI in generating the Three.js code for a mobile-first version of "Mope.io". *** Please use Three.js to generate a **mobile-first game** with the theme "**Mope.io Clone: Evolutionary Survival**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Use a **2D flat vector aesthetic rendered in a 3D engine**. All characters (animals) should be represented as simple **CircleGeometries** with flat-colored textures or composed of primitive shapes (circles for bodies, smaller circles for eyes/ears). The art style must remain "cute" and clean, similar to the original screenshot (bright colors, bold outlines). * **The Map**: Create a large, flat plane (`PlaneGeometry`) with a tiling grid texture (light green background with slightly darker green grid lines) to represent the "Land" biome. Add scattered static elements like "Water Holes" (blue circles), "Berry Bushes" (green circles with small red dots), and "Rocks" (grey circles). * **Player & Enemy Models**: * **Mouse (Starter)**: Grey circle body, small black eyes, pink nose. * **Fox (Mid-tier)**: Orange circle body, triangular white patches, black eyes. * **Lion/Predator (High-tier)**: Yellow circle body with a jagged mane outline. * **Performance**: Since this is mobile-first, avoid complex lighting. Use `MeshBasicMaterial` for all objects to ensure high FPS on mobile devices. Use object pooling for food items (berries/water) to avoid garbage collection stuttering. ### 2. Audio Requirements * **BGM**: A lighthearted, looping, bouncy orchestral track (pizzicato strings, marimba) that feels playful but slightly tense to encourage survival. * **Sound Effects (SFX)**: * **Eating**: A crisp "pop" or "crunch" sound when consuming food/berries. * **Drinking**: A soft "slurp" liquid sound when near water spots. * **Level Up/Evolve**: A rising magical chime or positive fanfare. * **Damage/Death**: A quick "squeak" or "thud" sound. * **Boost**: A "whoosh" wind sound when the player runs. ### 3. Gameplay Loop * **Core Mechanic**: The player starts as a "Mouse". They must move around the map to eat red "Berries" (XP) and blue "Water Drops" (Hydration). * **Evolution System**: Upon reaching a specific XP threshold, the player's circle grows larger, and the model texture swaps to the next tier (Mouse -> Fox -> Lion). * **Predator/Prey Logic**: * **Edible**: Animals smaller than the player (Green outline indicator). * **Threat**: Animals larger than the player (Red outline indicator). * **Neutral**: Animals of the same species/size (No collision damage). * **Water Mechanic**: A "Water Bar" slowly depletes over time (and depletes faster when boosting). Players must stand on blue "Water Spots" to refill. If water hits 0, health drains. * **Victory/Loss**: The game is endless. "Game Over" occurs if eaten by a larger predator or thirst kills the player. Display a "You Died" overlay with a "Respawn" button. ### 4. Mobile Controls & Interaction * **Movement (Virtual Joystick)**: Implement an invisible or semi-transparent **Virtual Joystick** on the left side of the screen. The player moves relative to the joystick angle. * **Boost (Action Button)**: Add a large, circular "Sprint/Boost" button on the bottom-right of the screen. Holding this depletes water rapidy but increases movement speed by 50%. * **Camera**: Use an Orthographic Camera (`OrthographicCamera`) locked to the player's X/Z position (top-down view). The camera zoom should slightly pull back as the player grows larger to maintain field of view. * **UI/HUD**: * **XP Bar**: A green progress bar at the bottom center. * **Water Bar**: A blue bar just below the XP bar. * **Leaderboard**: A small, semi-transparent list in the top-right showing the "Top 5 Animals". * **Feedback**: Trigger a mild screen shake (camera jitter) when the player gets hit or evolves. Use mobile vibration API (`navigator.vibrate`) when taking damage. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
