Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Sierra 7 - Tactical Vector Shooter**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: "Minimalist Tactical Noir". The game must strictly use a high-contrast, vector-art aesthetic. * **Palette**: Predominantly Greyscale (Whites, Greys, Blacks) with a single accent color: **Red** (used strictly for blood effects and critical UI warnings). * **Models**: Low-poly geometry using `THREE.MeshBasicMaterial` (unlit) or Toon Shaders to simulate 2D vector art. * **Characters**: Enemies must be rendered as pure **Black Silhouettes** to contrast sharply against the Light Grey/White backgrounds (office walls, corridors). * **Environment**: Indoor tactical settings (corridors, rooms). Use simple box geometry for walls and crates. * **Effects**: Minimalist particle systems for blood splatters (red squares/triangles) and gun muzzle flashes (white starbursts). * **Mobile Optimization**: * Use object pooling for bullets and particle effects to maintain 60 FPS. * Limit draw calls by merging static environment geometry. * No expensive real-time shadows; bake lighting into textures or use vertex colors if needed. ### 2. Audio Requirements * **BGM**: A tense, low-frequency ambient drone or suspenseful industrial synth track. It should increase in tempo during firefights. * **SFX**: * **Gunshots**: Crisp, realistic, and loud (not arcade-style). Different sounds for Player (Silenced Pistol/Rifle) vs. Enemy (AK-47/SMG). * **Feedback**: A "thud" or "squelch" sound for bullet impacts on enemies. * **Voice**: Minimal tactical chatter (e.g., "Contact!", "Reloading") triggered randomly by enemy spawn. * **UI**: Sharp, metallic clicks for button presses. ### 3. Gameplay Loop * **Genre**: On-Rails First Person Shooter (Arcade Style). * **Core Mechanic**: The player character automatically moves between "Cover Points". When at a cover point, the camera locks, and enemies pop out from behind obstacles or doors. * **Combat**: * Enemies appear and have a "reaction timer" (visualized by a filling ring or bar). If the player doesn't kill them before the timer fills, the player takes damage. * **Headshots**: Instantly kill the enemy and grant extra score. * **Body shots**: Require 2-3 hits to kill. * **Progression**: Player clears a room -> Camera automatically pans/moves to the next room -> New wave of enemies. * **Win/Loss**: Level complete after clearing 3 rooms. Game Over if Health reaches 0. ### 4. Mobile Controls & Interaction * **Screen Orientation**: **Landscape** (Essential for FOV). * **Control Scheme (Two-Handed)**: * **Left Side of Screen**: Invisible "Touch & Drag" area to move the aiming reticle (Crosshair). The sensitivity should be tuned for precision. * **Right Side of Screen**: Large "Fire" button (bottom right) and a smaller "Reload" button (top right). * **Alternative (Easier Implementation)**: "Tap to Fire" where the gun shoots exactly where the player taps on the screen (Raycasting), but with weapon sway added for difficulty. * **UI Elements**: * **Crosshair**: A simple, high-contrast dot or circle in the center of the screen. * **Ammo Counter**: Simple numbers (e.g., "7 / 21") in the corner. * **Health**: Screen vignette turns red as health gets low. * **Haptic Feedback**: Trigger vibration (using `navigator.vibrate`) on shooting and a longer vibration when taking damage. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
