Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Pixel Physics Playground**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Pixel Art/Voxel Hybrid style. Characters and objects should be constructed from flat 2D sprites or slightly extruded geometries (like cardboard cutouts) to mimic the "Playground" ragdoll aesthetic seen in the reference. * **Camera:** Fixed side-view orthographic camera to simulate a 2D plane, but with depth for layering objects. * **Characters:** * *Humans/Soldiers:* Blocky heads, separate limb segments (ragdoll ready), pixelated textures (skin tone, military green vests, helmets). * *Zombies:* Green-skinned variants, slightly disheveled textures. * **Weapons & Items:** Pixelated Assault Rifles (AK-47 style), Grenades, Crates, and Bricks. * **Environment:** A simple grid-like background or a flat "laboratory" gray background to emphasize the foreground action. * **Mobile Optimization:** Use instanced rendering for particles (blood, debris) and low-polygon count for physics bodies. Ensure textures are low-res (nearest-neighbor filter) to maintain the retro pixel look without blurring. ### 2. Audio Requirements * **BGM:** A quirky, low-fidelity 8-bit or chiptune track. It should be repetitive but catchy, sounding slightly "mischievous" rather than intense, matching the chaotic sandbox vibe. * **SFX:** * *Gunshots:* Crunchy, bit-crushed firing sounds. * *Impacts:* "Thud" sounds for ragdolls hitting the ground; squishing sounds for gore/zombie hits. * *Explosions:* Loud, distorted white noise bursts for grenades. * *UI:* High-pitched "blips" for selecting items from the menu. ### 3. Gameplay Loop * **Core Mechanic:** Physics-based Sandbox. The player is effectively a "god" interacting with a simulated world. There is no strict "win" state, but rather a playground for experimentation. * **Spawn System:** A prominent toolbar allows the player to drag and drop entities into the world: Humans, Zombies, Weapons (Guns, Grenades), and Obstacles (Walls, Crates). * **Physics Interaction:** * *Ragdoll Physics:* Characters must have active ragdoll physics (limbs connected by joints). They should flop, fall, and react realistically to explosions or bullets. * *Infection Logic:* If a Zombie collides with a Human, the Human sprite tints green and behavior changes to "hostile" after a short delay. * *Destruction:* Crates and basic walls should break into smaller particles upon high-impact collisions (explosions). * **Combat:** Weapons can be equipped by dragging them onto a character's hand slot. Once equipped, the character automatically aims at the nearest hostile entity or fires when the player taps a "Fire" button associated with that character. ### 4. Mobile Controls & Interaction * **Touch Input:** * *Drag & Drop:* The primary interaction. Users drag items from a scrollable bottom menu bar into the main scene. * *Physics Drag:* Users can tap and drag any character's limb to pick them up and throw them around (like a ragdoll toy). * **UI Layout (Landscape Mode):** * *Sidebar/Bottom Bar:* A scrollable container holding icons (Heart for entities, Gun for weapons, Brick for walls). Icons must be at least 48x48px for touch targets. * *Action Buttons:* Small floating context buttons appear when a character is selected (e.g., "Activate" to fire a gun, "Delete" to remove). * *Clear Button:* A "Trash" icon in the top corner to reset the scene. * **Haptic Feedback:** Trigger a heavy vibration on explosions and a light tick vibration when placing objects. * **Performance:** Cap physics iterations to ensure 60fps on mobile browsers. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Playground is an innovative action sandbox game that puts unlimited creative power in your hands. This 2D cubic sandbox environment offers the perfect blend of construction and destruction, where you can build magnificent cities one moment and orchestrate epic zombie battles the next. Whether you're a creative builder or destruction enthusiast, Playground provides endless entertainment possibilities.

The game features a unique physics-based system that makes every interaction feel realistic and satisfying. From placing characters and weapons to constructing elaborate defenses, every element responds naturally to your commands, creating an immersive sandbox experience unlike any other.

Core Features

Unlimited Creative Freedom

Playground offers complete creative control over your gaming experience. Build towering structures, design complex battle scenarios, or simply experiment with different combinations of characters and weapons. The open-ended nature means there's no single "correct" way to play.

Diverse Character System

Choose from an extensive roster of characters including humans, zombies, pigs, and unique hybrid creatures like zombie-pigs. Each character type brings different dynamics to your sandbox, with special characters available as unlock rewards for dedicated players.

Extensive Weapon Arsenal

Equip your characters with an impressive variety of weapons ranging from basic handguns and rifles to powerful chainsaws and machine guns. The weapon system adds tactical depth to battles and creative destruction scenarios.

Explosive Mayhem

Access high-impact explosives including dynamite, grenades, and rockets for maximum destruction potential. These powerful tools are perfect for clearing large areas or creating spectacular chain reactions.

Building Materials

Construct protective barriers and structures using various materials like bricks, wood, grass, and asphalt. The building system allows for both functional defensive structures and creative architectural projects.

Equipment & Props

Customize your playground with protective gear like helmets and vests, plus environmental props including furniture, emergency cones, and decorative items to create the perfect setting for your scenarios.

Gameplay Mechanics

Zombie Transformation System

One of Playground's most engaging features is the zombie transformation mechanic. When zombies come into contact with human characters, they convert them into zombies, creating dynamic scenarios where careful positioning and strategy become crucial for survival.

Physics-Based Interactions

Every object in Playground responds to realistic physics, making interactions feel natural and satisfying. Watch as structures collapse realistically, explosions send debris flying, and characters react authentically to their environment.
