scene3d-interactions

name	scene3d-interactions
description	Use when making a Scene3D brick interactive — spin/inspect product viewers, click-to-explore demos, kiosk attract loops, or simple 3D mini-games. Covers the per-frame script (a pure expression evaluated every frame with time, dt, objects, camera, variables, keys, pointer in scope, returning a mutation map; statement-form scripts run once at mount), eventScript for key and pointer handling, raycast picking wired to BRICKS events and actions, and the imperative scriptMember API (addObject, removeObject, updateObject, setCamera, lookAt, playAnimation, stopAnimation, setBackground, setControls, screenshot, getSceneState, raycast). Includes movement and kinematics patterns — there is no physics engine, so no collisions or rigid bodies — plus performance budgets and connecting scene events to app state in the Property Bank. Triggers on "make it interactive", "clickable 3D objects", "rotate on touch", "simple 3D game", "attract loop". For static scene setup use scene3d-authoring.

Scene3D Interactions

Make a composed scene behave: motion, input, picking, and game loops. Exact signatures live in references/script-api.md; ready-made patterns in references/patterns.md.
