Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Era: Evolution - Time Travel Tower Defense**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** A 2.5D side-scrolling aesthetic using **Low-Poly 3D models** to ensure high performance on mobile devices. * **Camera:** Fixed Orthographic camera angled slightly from above-center, viewing the battlefield from the side (Left Base vs. Right Base). * **Dynamic Eras (Visual Evolution):** The environment and assets must support switching "themes" dynamically: * **Stone Age:** Bases are Caves. Ground is dirt/grass. Units are blocky cavemen with clubs. Font style mimics the "ERA" logo (cracked stone). * **Medieval Age:** Bases are Castles. Ground is cobblestone. Units are knights. * **Future Age:** Bases are Neon Bunkers. Ground is metal plating. Units are robots. * **Background:** A parallax scrolling background (Skybox or layered planes) that reflects the current era (e.g., volcanoes for Stone Age, flying cars for Future). * **Performance:** Use instanced mesh rendering for units if possible, or simple `BoxGeometry`/`CylinderGeometry` primitives with different colors to represent different unit types to keep the framerate high (60fps target). ### 2. Audio Requirements * **Adaptive BGM:** The Background Music must evolve with the gameplay. * *Era 1:* Rhythmic tribal drums and flutes. * *Era 2:* Orchestral brass and marching snares. * *Era 3:* Synth-wave/Techno beats. * **Sound Effects (SFX):** * **Summoning:** A distinct "pop" or "whoosh" when a unit is created. * **Combat:** "Thud" sounds for melee impacts, projectile sounds for ranged units. * **UI:** A heavy "stone sliding" sound for the main menu, and metallic "clicks" for upgrades (referencing the stone-to-metal transition in the logo). ### 3. Gameplay Loop * **Tug-of-War Mechanic:** * Player Base (Left) generates "Gold/Food" over time. * Player spends resources to summon units. * Units automatically move right and attack the first enemy they meet. * Enemy AI spawns waves from the Right Base. * **Evolution Mechanic:** A special "Evolve" button becomes available when enough XP/Gold is earned. Clicking it upgrades the entire visual theme and unit stats (Stone -> Iron -> Future). * **Win/Loss Condition:** Reduce the Enemy Base HP to 0 to win. If Player Base HP hits 0, Game Over. ### 4. Mobile Controls & Interaction * **Screen Orientation:** **Landscape Mode** is mandatory for the lane-defense layout. * **Touch Controls:** * **Unit Summoning Deck:** A horizontal bar at the **bottom of the screen** containing large, square icons (min 60x60px) for summoning units. This creates an easy "thumb zone." * **Camera Pan:** Allow single-finger drag on the battlefield area to pan the camera left/right. * **Feedback:** * Buttons must scale down slightly (`scale.set(0.9, 0.9, 0.9)`) on `touchstart` and bounce back on `touchend` to provide tactile feel. * Damage numbers should pop up and float upwards when units hit each other. * **UI Layout:** * Top Left: Player HP & Resources. * Top Right: Enemy HP. * Top Center: "Evolve" Button (prominent when ready). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
