Add 3D models (.glb/.gltf) to a Decentraland scene using GltfContainer. Covers loading models, positioning, scaling, colliders, and browsing the open-source 3D assets catalog for free CC0 models. Use when user wants to add models, import GLB files, or find free 3D assets.

Add click handlers, hover effects, pointer events, triggers, and raycasting to Decentraland scene entities. Use when user wants to make objects clickable, add interactions, detect player proximity, or handle user input.

Advanced input handling in Decentraland scenes. Use PointerLock to detect cursor capture state, InputModifier to freeze or restrict player movement, PrimaryPointerInfo for cursor position and world ray, inputSystem.getInputCommand for per-entity input polling, and keyboard patterns for WASD movement controls. Use when user wants custom input, cursor control, movement restriction, keyboard handling, FPS controls, or input polling.

Advanced rendering features in Decentraland scenes. Use Billboard to make entities face the camera, TextShape for 3D text, advanced PBR material properties like metallic/roughness/transparency, GltfNodeModifiers for per-node visibility and material overrides in GLTF models, and VisibilityComponent to show/hide entities. Use when user wants billboards, 3D text, text labels, material effects, transparency, glow, or model node control.

Animate objects in Decentraland scenes using Animator (GLTF animations), Tween (move/rotate/scale over time), and TweenSequence (chain animations). Use when user wants to animate, move, rotate, spin, slide, or create motion effects.

Build 2D user interfaces for Decentraland scenes using React-ECS. Create HUDs, menus, health bars, scoreboards, dialogs, buttons, and input forms. Use when user wants to add UI, HUD, buttons, text overlays, menus, or on-screen elements.

Control camera behavior in Decentraland scenes. Switch between first-person and third-person with CameraMode, force camera in regions with CameraModeArea, create cinematic scripted cameras with VirtualCamera, and read camera position/rotation via MainCamera. Use when user wants camera control, cinematic views, cutscenes, or camera mode switching.

Scaffold a new Decentraland SDK7 scene project from scratch. Creates scene.json, package.json, tsconfig.json, and src/index.ts with a basic scene setup. Use when user wants to start a new scene, initialize a project, or set up from an empty folder.

Deploy and publish a Decentraland scene to Genesis City (LAND-based). Use when user wants to deploy, publish, upload, go live, or make their scene accessible on parcels they own.

Deploy and publish a Decentraland scene to a World (personal 3D space). Use when user wants to deploy to a World, publish to a World, set up worldConfiguration, use a DCL NAME or ENS domain for deployment, or opt out of Places listing.

Add dynamic lighting and control environment settings in Decentraland scenes. Create point, spot, and directional lights with LightSource, configure shadows, control day/night cycle with SkyboxTime, detect realm info, and use emissive materials for glow effects. Use when user wants lights, shadows, skybox, day-night cycle, or glowing materials.

Synchronize state between players in Decentraland multiplayer scenes using CRDT-based networking. Use when user wants multiplayer, sync state, network entities, shared world state, or real-time collaboration.

Display NFT artwork and interact with blockchain from Decentraland scenes. Show NFTs using NftShape with frame styles, check player wallet with getPlayer, sign messages with signedFetch, interact with smart contracts using eth-connect and createEthereumProvider, and handle MANA transactions. Use when user wants NFTs, blockchain, wallet, smart contracts, Web3, or crypto.

Optimize Decentraland scene performance, reduce entity count, minimize triangle budgets, improve loading times, and stay within scene limits. Use when user wants to optimize, improve performance, fix lag, reduce load time, or check scene limits.

Work with player avatars in Decentraland scenes. Read player position and profile data, customize appearance with AvatarBase, trigger emotes with triggerEmote/triggerSceneEmote, read equipped wearables via AvatarEquippedData, attach objects to players with AvatarAttach, create NPC avatars with AvatarShape, and modify avatars in areas. Use when user wants player data, emotes, wearables, avatar attachments, or NPCs.
