Add 3D Assets Replace basic geometric shapes (BoxGeometry, SphereGeometry) with real 3D models. Characters get custom Meshy AI-generated models with rigging and animation. World objects get generated or sourced from free libraries. Instructions Analyze the game at $ARGUMENTS (or the current directory if no path given). First, load the game-3d-assets skill and the meshyai skill for the full model pipeline, AssetLoader pattern, Meshy generation, and integration patterns. Step 1: Get Meshy API Key Check if MESHY_API_KEY is set. If not, ask the user: I'll generate custom 3D models with Meshy AI for the best results. You can get a free API key in 30 seconds: Sign up at https://app.meshy.ai Go to Settings → API Keys Create a new API key What is your Meshy API key? (Or type "skip" to use free model libraries instead) Step 2: Audit Read package.json to confirm this is a Three.js game (not Phaser — use /add-assets for 2D games) Read src/core/Constants.js for entity types, sizes, colors Read entity files ( src/gameplay/.js , src/entities/.js ) — find BoxGeometry , SphereGeometry , etc. Read src/level/LevelBuilder.js for environment primitives List every entity using geometric shapes Identify which entity is the player character (needs animated model) Step 3: Plan Split entities into two categories: Animated characters (player, enemies with AI) — generate with Meshy AI: Entity Meshy Prompt Notes Player "a heroic knight, low poly game character, full body, t-pose" Generate → rig → animate Enemy "a goblin warrior with a club, low poly game character" Generate → rig → animate If Meshy unavailable, fall back to 3d-character-library/ : Soldier — realistic military (Idle, Walk, Run) — best default Xbot — stylized mannequin (idle, walk, run + additive poses) RobotExpressive — cartoon robot (Idle, Walking, Running, Dance, Jump + 8 more) Fox — low-poly animal (Survey, Walk, Run) — scale 0.02 World objects (buildings, props, scenery, collectibles) — generate with Meshy or search free libraries: Entity Meshy Prompt Fallback Source Tree "a low poly stylized tree, game asset" Poly Haven House "a medieval house, low poly game asset" Poly Haven Barrel "a wooden barrel, low poly game asset" Poly Haven Coin "a gold coin, game collectible item" Sketchfab Step 4: Generate / Download With Meshy (preferred):

Generate characters

MESHY_API_KEY

< key

node < plugin-root

/scripts/meshy-generate.mjs \ --mode text-to-3d \ --prompt "a heroic knight, low poly game character, full body" \ --polycount 15000 --pbr \ --output public/assets/models/ --slug player

Rig characters for animation

MESHY_API_KEY

< key

/scripts/meshy-generate.mjs \ --mode rig --task-id < refine-task-id

--height 1.7 \ --output public/assets/models/ --slug player-rigged

Generate static props

MESHY_API_KEY

< key

node < plugin-root

/scripts/meshy-generate.mjs \ --mode text-to-3d \ --prompt "a wooden barrel, low poly game asset" \ --polycount 5000 \ --output public/assets/models/ --slug barrel Without Meshy (fallback):

Characters — copy from library

cp < plugin-root

/3d-character-library/models/Soldier.glb public/assets/models/

World objects — search and download

node < plugin-root

/scripts/find-3d-asset.mjs --query "barrel" --source polyhaven \ --output public/assets/models/ --slug barrel Step 5: Integrate Create src/level/AssetLoader.js — use SkeletonUtils.clone() for animated models (import from three/addons/utils/SkeletonUtils.js ). Regular .clone() breaks skeleton → T-pose. Add CHARACTER to Constants.js with path , scale , facingOffset , clipMap Add ASSET_PATHS and MODEL_CONFIG for static models Update Player.js : THREE.Group as position anchor loadAnimatedModel() + AnimationMixer fadeToAction() for idle/walk/run crossfade Camera-relative WASD via applyAxisAngle(_up, cameraAzimuth) Model facing: atan2(v.x, v.z) + CHARACTER.facingOffset model.quaternion.rotateTowards(targetQuat, turnSpeed * delta) Update Game.js : Add OrbitControls — third-person camera orbiting player Camera follows: move orbitControls.target + camera.position by player delta Pass orbitControls.getAzimuthalAngle() to Player for camera-relative movement Replace environment primitives with loadModel() calls + .catch() fallback Add THREE.GridHelper for visible movement reference Preload all models on startup with preloadAll() for instant loading Step 6: Tune & Verify Run npm run dev — walk around with WASD, orbit camera with mouse Confirm character animates (Idle when stopped, Walk when moving, Run with Shift) Adjust MODEL_CONFIG values (scale, rotationY, offsetY) per model Run npm run build to confirm no errors Generate ATTRIBUTION.md from .meta.json files Next Step Tell the user: Your 3D game now has custom models! Characters were generated with Meshy AI (or sourced from the model library), rigged, and animated. World objects are loaded from GLB files. Files created: src/level/AssetLoader.js — model loader with SkeletonUtils public/assets/models/ — generated and downloaded GLB models OrbitControls third-person camera Controls: WASD to move, Shift to run, mouse drag to orbit camera, scroll to zoom. Run the game to see everything in action. Adjust MODEL_CONFIG in Constants.js to fine-tune scale and orientation.
