Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Cry Islands: Mobile Ops**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Realistic but optimized "Low-Poly" aesthetic similar to early 2000s PC shooters. The atmosphere should be slightly gritty and desaturated. * **Terrain Generation**: Create a procedural island terrain using a heightmap. The center should be hilly with green grassy textures, flattening out towards the coast into sandy beaches. Surround the island with a shader-based ocean (moving vertex waves). * **Key Structures**: Based on the reference, generate a military outpost including: * Rusty Quonset huts (semi-cylindrical hangars) with corrugated metal textures. * A tall wooden/metal watchtower for verticality. * Shipping containers (Red/Green) scattered to provide tactical cover. * An asphalt airstrip or road cutting through the grass. * **Atmosphere**: Implement `THREE.FogExp2` (color: #C0C0C0, density: 0.015) to simulate the overcast/foggy weather seen in the screenshot and to hide the render distance for mobile performance optimization. * **Performance**: Use `InstancedMesh` for vegetation (pine trees, grass clumps) to maintain high frame rates on mobile devices. Limit texture sizes to 512x512. ### 2. Audio Requirements * **BGM**: A suspenseful, ambient track featuring low-frequency synth drones and distant tribal percussion to evoke a sense of isolation and danger (reminiscent of *Far Cry* exploration music). * **Sound Effects (SFX)**: * **Weaponry**: Loud, punchy gunfire with slight echo; mechanical reloading sounds. * **Environment**: Constant wind noise, ocean waves lapping at the shore. * **Movement**: Different footstep sounds based on surface (grass = soft crunch, metal = clank, asphalt = hard tap). * **UI**: Metallic "clicks" for button presses. ### 3. Gameplay Loop * **Objective**: The player spawns on the beach and must infiltrate the airfield outpost shown in the screenshot. The goal is to eliminate all patrolling AI guards or locate a specific "Intel Laptop" inside the main hangar. * **Mechanics**: * **FPS Combat**: Hitscan shooting mechanics. * **Exploration**: Open movement around the island. * **Vehicle System**: (Optional complexity) A simple drivable jeep (cube physics) available near the spawn point to traverse the map faster. * **Enemies**: Simple state-machine AI (Patrol -> Alert -> Attack). They should have a detection radius and fire projectiles at the player. * **Win/Loss**: * **Win**: All enemies cleared or Intel collected (show "Mission Accomplished" overlay). * **Loss**: Player health reaches 0 (show "Killed in Action" overlay with a 'Retry' button). ### 4. Mobile Controls & Interaction * **Screen Orientation**: Locked to **Landscape Mode**. * **Touch Controls**: * **Left Half of Screen**: Static or dynamic Virtual Joystick for movement (WASD equivalent). * **Right Half of Screen**: Touch-drag area for camera rotation (aiming). * **Action Buttons**: Large, thumb-friendly buttons (min 60px diameter) on the right side for: * **Shoot** (largest button). * **Jump**. * **Reload**. * **Interact** (Contextual button: appears only when near a vehicle or health kit). * **UI/HUD**: * **Health & Armor**: Visual bars at the top-left or bottom-center. * **Mini-map**: Top-right circular radar showing enemy blips (red) and player (green). * **Crosshair**: A static white dot or cross in the center of the screen that expands slightly when firing. * **Feedback**: * **Haptic**: Trigger `navigator.vibrate(50)` on shooting and `navigator.vibrate([100, 50, 100])` on taking damage. * **Visual**: Camera shake effect when shooting; Red vignette overlay when health is low. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
