What problem does it solve? Decentraland SDK7 scene developers frequently hit silent failures when manipulating the player: mutating the player Transform does nothing, held items parented to the wrong entity lose camera pitch, and custom emotes fail in production due to file naming rules. This Skill provides verified patterns for every player and avatar interaction so these bugs are avoided. ## Core Features & Use Cases - Player Data & Position: Read the player Transform, profile (name, wallet, guest status), and fetch off-scene avatar appearances from the catalyst /lambdas/profile endpoint. - Attachments & Held Items: Attach cosmetics via AvatarAttach anchor points, or parent aim-sensitive items to engine.CameraEntity and body-fixed items to engine.PlayerEntity with clear guidance on which to choose. - Emotes, Teleport & Modifiers: Trigger built-in and custom _emote.glb emotes with lifecycle detection, teleport with movePlayerTo, adjust locomotion via AvatarLocomotionSettings, and hide avatars or nametags with AvatarModifierArea. - Use Case: Build a multiplayer game where players carry a first-person flashlight, trigger a wave emote on puzzle completion, and get teleported into a final room while nametags are hidden. ## Quick Start Ask the assistant to write Decentraland SDK7 code that teleports the player to a position and attaches a hat to their avatar using this skill.
