Please use Three.js to generate a **mobile-first game** with the theme "Zombie Defence 2 - Mobile Remake". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: 3D Stylized Stickman (Low-poly). Use `THREE.CapsuleGeometry` or cylinders to construct characters to mimic the classic "Stick Figure" aesthetic but with depth. * **Player Character**: A bright Green Stickman stationed behind a defensive barricade (sandbags or a brick wall) on the left side of the screen. Weapon should be a low-poly Assault Rifle. * **Enemies (Zombies)**: Grey and Red Stick figures with varying walking animations (shambling, running). * **Environment**: A gritty urban setting. A grey asphalt road stretching from the right (spawn point) to the left (player base). Background should be a simple grey brick wall or concrete texture with distance fog (`THREE.Fog`) to mask enemy spawning. * **VFX**: * **Blood**: heavily emphasized based on the "Bloody" tag. Use `THREE.Points` or a particle system to generate red square bursts when enemies are hit. * **Muzzle Flash**: Yellow point light/mesh flashing at the gun barrel. * **Airstrike**: A shadow growing on the ground followed by a large explosion particle effect. * **Mobile Optimization**: Use instanced mesh rendering (`THREE.InstancedMesh`) for the zombie horde to maintain 60 FPS on mobile devices. Limit dynamic lights to 1-2 (sunlight and muzzle flash). ### 2. Audio Requirements * **BGM**: Fast-paced, industrial rock or dark electronic track with a heavy bassline to induce tension. * **Sound Effects (SFX)**: * **Gunfire**: Realistic, punchy assault rifle sounds (varied pitch to avoid repetition). * **Impact**: "Squish" or wet thud sounds when bullets hit zombies. * **Zombies**: Groans and growls that increase in volume as they get closer. * **Airstrike**: A jet flyover sound followed by a booming explosion. * **UI**: Mechanical clicks for buttons; alarm sound when base health is low. ### 3. Gameplay Loop * **Core Mechanic**: Static Tower Defense / Shooter. The player cannot move, only aim and shoot. * **Objective**: Defend the barricade from waves of zombies coming from the right side of the screen. * **Win/Loss**: * **Loss**: Zombies reach the barricade and deplete the "Base HP" to 0. * **Win**: Survive all waves (or infinite high-score mode). * **Weaponry**: Automatic rifle. Infinite ammo but requires a "Reload" time (2 seconds) after a certain number of shots (simulated magazine). * **Special Ability (Airstrike)**: A powerful AOE attack that kills all visible zombies. Limited to 1 use per wave or has a very long cooldown (30s). Triggered by a specific UI button. ### 4. Mobile Controls & Interaction * **Orientation**: **Landscape** mode (essential for horizontal defense view). * **Shooting Control**: * **Touch-to-Aim/Fire**: The gun automatically tracks the user's finger on the screen. Holding down on the screen fires the weapon continuously (Raycasting from camera to world plane). * Implement an "Auto-fire" toggle for accessibility, or stick to "Hold to Shoot". * **UI Layout**: * **Top Left**: Health Bar (Green to Red gradient) and Wave Counter. * **Top Right**: Score / Kill Count. * **Bottom Right**: "Airstrike" Button (Large, distinct icon, turns grey when on cooldown). Recommended size: 64x64px minimum for touch targets. * **Reload Indicator**: A circular progress bar appearing near the crosshair/player when reloading. * **Feedback**: * **Haptic Feedback**: Trigger a short vibration (`navigator.vibrate`) on every shot fired and a heavy vibration when the base takes damage. * **Camera Shake**: Subtle camera shake (`Math.sin` on camera position) when shooting or when explosions occur.
