Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Bloons Tower Defense 4 Remake**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Recreate the classic Flash game aesthetic using a 2.5D approach (flat sprites or low-poly 3D models facing the camera). Use bright, high-saturation colors characteristic of the "Bloons" series (vibrant greens for grass, bright blues for sky, and distinct colors for different balloon tiers). * **Camera:** Fixed top-down orthographic camera to simulate the classic 2D view while utilizing Three.js rendering capabilities. * **Map Design:** A winding path made of light dirt texture cutting through a green grassy field. The path should have clear entry and exit points. * **Characters (Towers):** * **Dart Monkey:** A simple brown monkey model (or sprite billboard) holding a dart. * **Cannon:** A black cylinder on a wooden base. * **Tack Shooter:** A pink/metallic ring structure. * **Enemies (Bloons):** Spherical geometries with simple shading representing balloons. Different colors indicate health/speed (Red = 1 hit, Blue = 2 hits/faster, Green = 3 hits). When popped, they should spawn a simple particle burst effect matching their color. * **Performance Optimization:** Use InstancedMesh for the balloons (as there will be many on screen) to maintain 60FPS on mobile devices. Use simple geometries for projectiles. ### 2. Audio Requirements * **BGM:** Upbeat, looping marimba or synth-flute track that feels "tropical" and "playful," reminiscent of early 2010s Flash games. * **Sound Effects (SFX):** * **Pop:** A distinct, high-pitched rubber snapping sound (essential for feedback). * **Shoot:** A "whoosh" for darts and a "thud" for cannons. * **Placement:** A satisfying "clump" sound when a tower is successfully placed on the map. * **Error:** A buzzer sound if the player tries to place a tower on the path or without enough money. ### 3. Gameplay Loop * **Core Logic:** Waves of balloons travel along a predefined path from Start to End. If a balloon reaches the End, the player loses lives. * **Economy:** Player starts with a set amount of cash. Popping balloons grants cash ($1 per layer popped). * **Building:** Players spend cash to place towers on non-path areas. * **Combat:** Towers automatically detect enemies within a circular radius. * *Dart Monkey:* Shoots single projectiles. * *Cannon:* Shoots explosive projectiles (Area of Effect damage). * **Progression:** Waves get progressively harder (more balloons, faster types, higher health). Game Over if lives reach 0. ### 4. Mobile Controls & Interaction * **Orientation:** Landscape mode is mandatory to maximize the view of the map. * **Tower Selection (UI):** A sidebar or bottom bar on the right/bottom containing tower icons. Icons must be large (minimum 60x60px) for easy tapping. * **Drag-and-Drop Construction:** * **Action:** Player touches a tower icon -> drags finger onto the map -> a "ghost" tower follows the finger showing range (white circle) and validity (Green = Valid, Red = Invalid). * **Release:** Lifting the finger places the tower if the position is valid and player has funds. * **Tower Inspection:** Tapping an existing tower selects it, showing its range circle and an upgrade/sell menu (large buttons) in the UI area. * **Feedback:** Small screen shake effect when a "MOAB" or large boss balloon is popped. Haptic feedback (vibration) when a tower is placed or lives are lost. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
