Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Diep.io Clone (3D Top-Down Tank Shooter)". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Minimalist geometric aesthetic ("2.5D" style). The game should look like the classic 2D .io game but rendered with 3D primitives. * **Player Tank**: A `CylinderGeometry` (the body, Blue color) with a horizontal `BoxGeometry` attached as the cannon barrel. The tank should rotate to face the aiming direction. * **Fodder/Shapes (XP sources)**: * Yellow Squares (Low XP): `BoxGeometry`. * Red Triangles (Medium XP): `TetrahedronGeometry` or `ConeGeometry`. * Purple Pentagons (High XP): `CylinderGeometry` (5 segments). * *Note*: These shapes should slowly rotate on their local axes to add visual interest. * **Background**: A large, light grey plane with a darker grid pattern texture (`GridHelper` logic) to emphasize movement. * **Performance Optimization**: Use `InstancedMesh` for rendering projectiles (bullets) and background shapes to ensure 60FPS on mobile devices. Low polygon counts for all models. Shadows should be disabled or baked to save battery. ### 2. Audio Requirements * **BGM**: An upbeat, repetitive chiptune or minimal techno loop. It should be low-volume and focus on concentration. * **Sound Effects (SFX)**: * **Shooting**: A sharp, short "pew" or "thud" sound (varied slightly in pitch to avoid fatigue). * **Impact**: A metallic "tink" when bullets hit shapes/enemies. * **Destruction**: A crunching or shattering sound when a shape or tank is destroyed. * **Level Up**: A rising, positive chime sound. ### 3. Gameplay Loop * **Core Mechanic**: The player controls a tank in an open arena. The goal is to survive and grow. * **Progression**: Destroying shapes drops "XP". As XP fills a bar, the player levels up. * **Upgrade System**: Upon leveling up, the player receives a skill point to upgrade one of 8 stats (Regen, Max Health, Body Damage, Bullet Speed, Penetration, Bullet Damage, Reload, Move Speed). * **Combat**: Bullets must have travel time (not hitscan). Shooting creates a small recoil force on the tank's movement. * **Win/Loss**: * **Loss**: HP reaches 0 (Game Over screen with final score). * **Win**: Technically endless, but high score is the goal. * **Enemy AI**: Simple AI bots that wander, aim at the player if in range, and shoot. ### 4. Mobile Controls & Interaction * **Control Scheme**: Dual Virtual Joysticks (Twin-stick shooter style). * **Left Stick**: Controls movement (WASD logic equivalent). * **Right Stick**: Controls aiming rotation and firing. Holding the stick in a direction fires continuously; releasing stops firing. * **Screen Orientation**: **Landscape Mode** only. * **UI Layout**: * **Upgrade Menu**: A collapsible or semi-transparent panel on the **bottom-left** containing large buttons (min 44x44px) for the 8 stats. Buttons must handle multi-touch (tapping upgrade while moving). * **Health/XP**: Floating bars above the tank model for immediate feedback. * **Feedback**: * **Haptic**: Trigger a short vibration (using `navigator.vibrate`) when the player takes damage or destroys a large pentagon. * **Visual**: The tank should flash white briefly when taking damage. Floating text numbers pop up when damage is dealt. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Diep.io is one of the most popular .io games that combines strategy, skill, and fast-paced action in a massive multiplayer arena. Starting as a simple level 1 tank, players must survive, evolve, and dominate in an endless battlefield filled with geometric shapes, power-ups, and rival tanks from around the world.

The game features a clean, minimalist 2D design that focuses purely on gameplay mechanics. With its simple yet deep upgrade system, Diep.io offers countless hours of strategic tank warfare that appeals to both casual players and competitive gamers.

Core Features

Progressive Tank Evolution System

Diep.io's most compelling feature is its tank evolution system. Starting at level 1, players can advance up to level 45, with major upgrades available every 15 levels. Each evolution unlocks new tank classes with unique abilities:

  • Basic Tank : Your starting point with standard cannon
  • Twin : Dual cannons for increased firepower
  • Sniper : Long-range precision shooting
  • Machine Gun : Rapid-fire capability
  • Flank Guard : Multi-directional shooting
  • Destroyer : Massive damage output
  • Overlord : Command drone armies

Eight Customizable Stats

Every level gained provides upgrade points to enhance your tank across eight critical areas:

  • Health Regeneration : Recover from damage faster
  • Maximum Health : Increase your survivability
  • Body Damage : Deal damage through direct contact
  • Bullet Speed : Faster projectile velocity
  • Bullet Penetration : Pierce through multiple targets
  • Bullet Damage : Increased projectile damage
  • Reload Speed : Fire more frequently
  • Movement Speed : Navigate the battlefield quicker

Multiple Game Modes

Diep.io offers diverse gameplay experiences through various game modes:

  • Free-for-All : Classic survival mode where everyone fights everyone
  • Team Modes : 2-team or 4-team battles with colored bases
  • Tag : Dynamic team switching upon death
  • Maze : Navigate narrow corridors and ambush points
  • Domination : Control special turret points
  • Sandbox : Private mode for testing builds with friends

Gameplay Strategy

Early Game Survival

New players should focus on destroying geometric shapes scattered across the map to gain experience safely. Avoid confronting other players until you've reached at least level 15 and chosen your first tank evolution.

Mid-Game Development

Once you've selected your tank class, develop a focused upgrade strategy. Defensive builds prioritize health and regeneration, while offensive builds emphasize bullet damage and speed. Balanced builds offer versatility but may lack specialization.

Late Game Domination

High-level gameplay revolves around map control, strategic positioning, and team coordination in team modes. Master your chosen tank class's strengths and learn to exploit opponent weaknesses.
