MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Slingshot Fortress". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Cartoon aesthetic (vibrant, saturated colors). Use Three.js **OrthographicCamera** to maintain a strict 2D gameplay plane while allowing for 3D depth in background layers. * **Core Models (Low Poly / Primitives):** * **Slingshot:** A stylized Y-shaped wooden model anchored on the left side of the screen. * **Projectiles:** Sphere geometries with distinct textures/colors representing Stones (Grey), Bombs (Black with fuse), and Shurikens (Silver). * **Fortress Blocks:** Rectangular prisms and cubes representing Wood (brown, light mass), Stone (grey, heavy mass), and Glass/Ice (blue, fragile). * **Enemies:** "Sneaky hidden creatures" represented as simple, bright green or red round blobs/meshes with face textures. * **Environment:** Parallax background layers (close foreground grass, mid-ground trees, far background mountains/sky). * **Mobile Optimization:** Use **InstancedMesh** for repetitive building blocks to reduce draw calls. Limit real-time shadows; use baked lighting or ambient occlusion textures. ### 2. Audio Requirements * **BGM:** Upbeat, mischievous, orchestral-cartoon style loop (pizzicato strings, light percussion) similar to "sneaking" music. * **Sound Effects (SFX):** * **UI:** Soft "pop" sounds for button presses. * **Slingshot:** A stretching rubber band sound (pitch increases with tension) and a "thwack" upon release. * **Impact:** Distinct sounds for Wood (clack), Stone (thud), and Glass (shatter). * **Explosion:** muffled "boom" for TNT/Bombs. * **Enemy Defeat:** A comical "poof" or squeak sound. * **Score:** High-pitched "ding" when collecting diamonds. ### 3. Gameplay Loop * **Objective:** Eliminate all Enemy entities in the level by collapsing the structure or hitting them directly. * **Physics Engine:** Integrate a 2D physics engine (like **Matter.js** or Cannon.js locked to the Z-axis) to handle gravity, collision, mass, and structural stability. * **Turn Logic:** 1. **Aim Phase:** Player drags the active projectile in the slingshot. 2. **Launch Phase:** Player releases; projectile follows a physics arc. 3. **Ability Phase (Optional):** If the player taps the screen while the projectile is airborne, trigger a special effect (e.g., Bomb explodes immediately, Shuriken splits into three). 4. **Destruction Phase:** Physics simulation runs until movement settles. Points are awarded for damage caused and enemies popped. 5. **Check:** If enemies = 0, Level Win. If ammo = 0 and enemies > 0, Level Lose. * **Scoring:** Points for destruction magnitude + Bonus for unused projectiles. ### 4. Mobile Controls & Interaction * **Orientation:** Force **Landscape Mode** to allow viewing the slingshot and the target fortress simultaneously. * **Touch Controls:** * **Drag-to-Shoot:** Detect touch anywhere on the left 1/3 of the screen (or specifically on the slingshot). `TouchStart` anchors the band, `TouchMove` calculates tension/angle (clamped to a max distance), `TouchEnd` fires. * **Trajectory Guide:** Render a dotted line (using `THREE.Line` or sprites) showing the predicted path based on current drag tension. * **Ability Activation:** A full-screen invisible button overlays the game view during the projectile's flight; a tap triggers the special ability. * **Camera Pan:** Allow the user to swipe left/right with two fingers to pan the camera to view the fortress before shooting. * **Feedback:** * **Haptic:** Trigger `navigator.vibrate(50)` on impact or explosion. * **Visual:** "Screen Shake" effect (camera jitter) when heavy structures collapse or TNT explodes. * **UI:** Large, thumb-friendly Pause/Restart buttons (min 44x44px) placed in the top corners, away from the aiming zone. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
