Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Hypper Sandbox Mobile". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: A "Garry's Mod" inspired aesthetic adapted for mobile. Use a bright, vibrant color palette. The environment should be a large, open "Grid Map" (infinite floor with a checkerboard texture for scale reference) or a flat grassy plain. * **Character & Objects**: * The player is a First-Person Controller (FPS camera). * **Spawnable Assets**: Include basic geometric primitives (cubes, spheres, ramps) representing building blocks, plus low-poly "props" like wooden crates, explosive barrels, and a simple vehicle model (car placeholder). * **Ragdolls**: If possible, include simple capsule-based humanoid dummies that react to physics (falling over when shot or hit). * **Mobile Optimization**: * Use `MeshLambertMaterial` or `MeshToonMaterial` for performance. * Limit real-time shadows to the main character/vehicle only. * Implement a simple fog effect to mask distant LOD limits. ### 2. Audio Requirements * **BGM**: A loop of calm, creative "building mode" music (lo-fi or soft electronic) that switches to a faster-paced rock/beat loop when the player equips a weapon or enters a vehicle. * **Sound Effects**: * **Physics**: Distinct sounds for wood impact, metal clanging, and explosion rumbles. * **Weapons**: "Pew" sounds for pistols, deep booms for RPGs, and a mechanical "click" for reloading. * **UI**: A satisfying "pop" sound when an object is spawned from the menu. ### 3. Gameplay Loop * **Core Mechanic**: Total freedom. The player spawns into the world with a "Tool Gun" (for moving/deleting objects) and a "Weapon" (for destruction). * **The "Tool Gun" Logic**: A raycaster mechanic that allows the player to pick up physics objects, freeze them in mid-air (kinematic toggle), or throw them. * **Construction**: Open the "Spawn Menu" -> Tap an item -> Item appears in front of the player. * **Destruction**: Switch to weapons to knock over stacks of crates or ragdoll dummies. * **Vehicle System**: Walk up to a vehicle object -> Context button appears -> Enter vehicle -> Camera switches to Third-Person -> Drive physics-based car. ### 4. Mobile Controls & Interaction * **Movement**: * **Left Thumb**: Virtual Joystick for WASD movement (Walking/Strafing). * **Right Thumb**: Invisible touch area for camera rotation (Look). * **Action Buttons (Right Side Overlay)**: * **Jump Button**: Bottom right corner. * **Shoot/Interact Button**: Large circular button above Jump. * **Crouch/Slide**: Smaller button near the bottom. * **UI & Menus**: * **Spawn Menu (Tab equivalent)**: A hamburger menu icon in the top-left. Tapping it pauses physics and opens a grid of spawnable icons. * **Weapon Wheel**: A swipe gesture on the weapon icon (top right) to cycle between Tool Gun, Pistol, and RPG. * **Context Action**: A "Hand" icon appears centrally when looking at an interactable object (like a vehicle or door) to replace the "E" key. * **Feedback**: Screen shake effect (camera jitter) on explosions or heavy impacts. Slight UI scale bounce when buttons are pressed. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Hypper Sandbox is the ultimate 3D physics playground where imagination meets action. This dynamic sandbox simulator empowers you to create entire worlds from scratch while engaging in thrilling combat scenarios. Whether you're building peaceful towns or orchestrating massive battles, Hypper Sandbox provides the tools and freedom to bring your wildest creations to life.

The game features realistic physics simulation that makes every interaction feel authentic. Buildings collapse realistically, vehicles respond naturally to terrain, and weapons behave with true-to-life ballistics. This attention to physics detail creates an immersive experience where your creations feel tangible and responsive.

Core Features

Unlimited Creative Building

Construct anything your imagination can conceive - from simple houses to sprawling metropolises. The intuitive building system lets you shape terrain, place structures, and design complex architectural projects. Every element responds to realistic physics, making your creations feel alive and interactive.

Dynamic Combat System

Equip yourself with a vast arsenal of weapons and vehicles for epic battles. The FPS combat mechanics are smooth and responsive, while the physics engine ensures that every explosion, collision, and destruction sequence feels impactful and realistic.

Multiple Game Modes

  • Free Mode : Unlimited resources and complete creative freedom
  • Private Mode : Create password-protected sessions for friends
  • Adventure Mode : Explore pre-built challenges and scenarios
  • Offline Mode : Play without internet connection

Multiplayer Experience

Team up with friends or players worldwide to collaborate on massive projects or engage in competitive battles. The multiplayer system supports various player counts and includes built-in chat functionality for seamless communication.

Advanced Physics Engine

Experience realistic object interactions, destructible environments, and natural movement mechanics. The sophisticated physics system makes every action feel consequential and every creation behave authentically.

Gameplay Mechanics

The game seamlessly blends construction and combat elements. Start by exploring the vast open world, then use the spawn menu to access building materials, weapons, and vehicles. Create fortifications and then test them against various weapons, or build race tracks for vehicle challenges.

The weapon selection system allows quick switching between different tools - from construction implements to combat gear. Vehicle mechanics include realistic driving physics for cars, tanks, helicopters, and more specialized transport options.

Operation Guide

Basic Controls

  • WASD Keys : Move your character in all directions
  • Space Bar : Jump and climb obstacles
  • Tab Key : Open spawn menu to access all items
  • Left Mouse : Primary action (shoot, use tools, interact)
  • Mouse Scroll : Quick weapon and tool selection
  • R Key : Reload weapons and reset tools
  • E Key : Enter vehicles and interact with objects
  • F Key : Exit vehicles and mounted weapons
  • T Key : Open chat for multiplayer communication
  • P Key : Pause game and access settings

Building Tips

Start with simple structures to familiarize yourself with the physics system. Use the spawn menu to access building materials, then experiment with different combinations. Remember that all structures must obey physics laws - build stable foundations for larger constructions.

Combat Strategies

Utilize the environment to your advantage in battles. Destructible terrain allows for dynamic combat scenarios where cover can be destroyed and new tactical positions created. Experiment with different weapons to understand their physics properties and optimal use cases.
