Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Castle Defender Saga - Tactical Battle**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Create a vibrant, **Cel-Shaded / Toon-Style** aesthetic. Avoid realistic textures; instead, use flat colors with thick outlines (using `THREE.EdgesGeometry` or custom shaders) to mimic the vector art style of the reference image. * **Camera Angle:** Set up an **Orthographic Camera** positioned at a side-view or slight isometric angle (e.g., `position.set(20, 20, 20)` looking at center) to replicate the 2D "lane defense" feel in a 3D space. * **The Player's Base (Left Side):** A tall, blocky medieval stone tower. It should have a blue banner, crenelations on top, and spots where archers can be stationed. Use simple geometries (cubes, cylinders) with low polygon counts. * **The Enemy Base (Right Side):** A darker, perhaps jagged or spiked tower (Red or Black theme) to distinguish it from the player's. * **Environment:** A simple green plane for the ground with a striped grass texture. Scattered low-poly pine trees in the background (billboarded sprites or simple cones) to add depth without hurting mobile performance. A bright blue skybox with white "sun rays" or clouds. * **Units:** * **Player Units:** Simple blue low-poly knights (melee) and archers (ranged). * **Enemy Units:** Red goblins or knights. * **Projectiles:** Simple colored spheres or lines for arrows/magic. * **Performance:** Strictly limit geometry complexity. Use `InstancedMesh` for rendering multiple units (soldiers/enemies) to maintain 60 FPS on mobile browsers. ### 2. Audio Requirements * **BGM (Background Music):** An upbeat, orchestral "Marching to War" track. Think snares, trumpets, and flutes, but kept light and casual—heroic yet repetitive enough for a strategy loop. * **SFX (Sound Effects):** * **UI:** A satisfying "wood block" click sound for upgrading towers and a "coin chink" sound for purchasing units. * **Combat:** "Thwack" sounds for sword hits, "Whoosh" for arrows flying. * **Event:** A triumphant trumpet fanfare for Victory, and a descending "sad trombone" or crumbling stone sound for Defeat. ### 3. Gameplay Loop * **Core Mechanic:** A "Tug of War" lane defense system. * **Passive Income:** The player generates Gold and Mana automatically over time. * **Unit Spawning:** Player taps icons to spend Mana/Gold to spawn units (Swordsman, Archer, Cavalry) from the Left Tower. These units walk automatically to the Right in a straight line. * **Tower Defense:** Archers stationed *on* the tower fire automatically at incoming enemies within range. * **Enemy Logic:** The enemy base spawns waves of red units that march Left. * **Combat:** When opposing units meet, they stop and attack each other until HP reaches zero. * **Win/Loss Condition:** * **Win:** Destroy the Enemy Tower (Right side) HP to 0. * **Loss:** Player Tower (Left side) HP hits 0. * **Progression:** Between waves or during battle, the player can click an "Upgrade" button to increase Mana regeneration or Tower HP. ### 4. Mobile Controls & Interaction * **Orientation:** **Landscape Mode** is mandatory for this lane-based defense view. * **Main Interaction (Bottom Bar UI):** * Create a fixed HTML overlay at the bottom of the screen. * **Unit Cards:** Large, tappable square buttons (minimum 60x60px) representing units to spawn. These must visually "cooldown" (grey out) when Mana is insufficient. * **Upgrade Buttons:** Distinct buttons for "Upgrade Tower" and "Upgrade Income." * **Visual Feedback:** * When a button is tapped, it should scale down slightly (CSS active state). * Spawn floating text (e.g., "-50 Gold", "+10 EXP") over the tower when actions occur. * Shake the camera slightly using a simple sine wave function when a tower takes damage to provide impact feedback without heavy physics. * **Touch Optimization:** Ensure `pointer-events: none` on non-interactive UI layers so touches pass through to the game world if necessary (though most control is via the HUD). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
