Please use Three.js to generate a **mobile-first game** with the theme "Stickman Challenge - Physics Puzzle". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D aesthetic using an Orthographic Camera to simulate a flat puzzle view but with 3D depth. The art style should be vibrant, cartoonish, and vector-like (High saturation colors). * **Background:** A dynamic background featuring a bright blue sky with a slowly rotating radial sunburst effect (lighter blue rays) to maintain energy without distraction. * **Grid System:** Render a subtle, dotted grid overlay on the Z=0 plane to guide the player's placement of objects. * **Characters (Stickmen):** Use simple 3D cylinder/sphere compositions to create "Ragdoll" stickmen. They should be dark blue with a glowing white "rim light" or outline shader to pop against the background. * **Interactables:** * **Trampolines:** Pill-shaped, glossy yellow geometry. They must look bouncy. * **Obstacles:** Rotating circular sawblades (metallic grey/silver) with jagged edges. * **Collectibles:** Floating, rotating golden stars with a particle emitter trail. * **Optimization:** Use low-poly geometries (CylinderGeometry, BoxGeometry) and share materials (InstancedMesh) where possible to maintain high FPS on mobile browsers. Use simple Lambert or Toon materials. ### 2. Audio Requirements * **BGM:** A funky, upbeat, and looping "casual puzzle" track (think marimba, light bass, and synth) to keep the mood lighthearted. * **Sound Effects (SFX):** * **Placement:** A satisfying "pop" or "click" sound when a trampoline snaps to the grid. * **Bounce:** A comical spring/boing sound triggered on collision with trampolines (pitch varied by velocity). * **Collect:** A high-pitched "ding" or chime when a star is gathered. * **Failure:** A "buzz" or cartoonish "splat" sound if a stickman hits a sawblade. * **Success:** A short victory fanfare when the level is cleared. ### 3. Gameplay Loop * **Phase 1: Planning (Paused Physics):** * The player is presented with a level layout containing a Stickman spawner, fixed obstacles (saws), and target stars. * The player has a limited inventory of **Trampolines**. * The player drags trampolines from a UI dock and places them onto the dotted grid. They can rotate the trampolines to adjust bounce angles. * **Phase 2: Simulation (Active Physics):** * Player taps a prominent "GO" button. * Physics (using a library like Cannon.js or Ammo.js integrated with Three.js) activates. Gravity pulls the stickmen down. * Stickmen fall, bounce off placed trampolines, and react to physics. * **Win Condition:** The stickmen physically collide with and "collect" all stars in the level. * **Lose Condition:** Stickmen fall off the screen bounds or collide with a Sawblade (triggering a ragdoll separation or reset). ### 4. Mobile Controls & Interaction * **Input System:** Use Three.js Raycaster mapped to Touch events for drag-and-drop functionality. * **Trampoline Manipulation:** * **Drag:** One-finger touch and drag to move the trampoline. * **Rotate:** While a trampoline is selected, show a UI ring or use a two-finger twist gesture to rotate it. Alternatively, a tap-to-rotate (45-degree increments) button appears near the selected object. * **UI Layout:** * **Portrait/Landscape Adaptive:** Ensure the camera zoom adjusts so the entire level fits within the screen width. * **HUD:** Large, thumb-friendly buttons (minimum 44px touch targets). Place the "GO" (Play) and "RESET" (Stop/Edit) buttons at the bottom right. * **Inventory:** A scrollable bar at the bottom center holding available trampolines. * **Feedback:** * **Haptics:** Trigger a short vibration (using `navigator.vibrate`) when a trampoline snaps to the grid or when a stickman bounces. * **Visuals:** Show a trajectory prediction line (dashed line) when dragging a trampoline to estimate the bounce angle. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
