--- name: threejs-controls description: "Addon camera and object manipulation controls: OrbitControls, MapControls, FlyControls, FirstPersonControls, TrackballControls, ArcballControls, DragControls, PointerLockControls, TransformControls; damping, target focal point, and integration with the animation loop. Use for editor-style navigation and gizmos—not a full game character controller stack; pair with Raycaster selection patterns in threejs-objects when transforming selections." --- ## When to use this skill **ALWAYS use this skill when the user mentions:** - Orbiting/panning/dolly around a target, inertia/damping, min/max distance/polar angles - Map-like pan (MapControls) or flying (FlyControls) - Transform gizmo translate/rotate/scale with `TransformControls` - Dragging objects in plane (DragControls), pointer lock FPS (PointerLockControls) **IMPORTANT: controls vs webxr** | Context | Skill | |---------|--------| | Desktop/browser camera nav | **threejs-controls** | | XR controller poses | **threejs-webxr** | **Trigger phrases include:** - "OrbitControls", "TransformControls", "MapControls", "PointerLockControls" - "轨道", "变换控制器", "漫游" ## How to use this skill 1. **Import** from addons path (**threejs-dev-setup**). 2. **Construct** with `(camera, domElement)`; for `TransformControls` also attach to renderer events. 3. **Animation loop**: when `enableDamping`, call `controls.update()` each frame. 4. **TransformControls**: wire `dragging-changed` to disable Orbit temporarily; sync with selection from **threejs-objects**. 5. **Constraints**: set min/max distance/angles to avoid flipping or underground views. 6. **Dispose**: `controls.dispose()` when tearing down. ### Example: OrbitControls with damping ```javascript import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; const controls = new OrbitControls(camera, renderer.domElement); controls.enableDamping = true; controls.dampingFactor = 0.05; controls.minDistance = 2; controls.maxDistance = 50; // Must call update() each frame when damping is enabled function animate() { controls.update(); renderer.render(scene, camera); } renderer.setAnimationLoop(animate); ``` See [examples/workflow-orbit-damping.md](examples/workflow-orbit-damping.md). ## Doc map (official) | Docs section | Representative links | |--------------|----------------------| | Controls | https://threejs.org/docs/OrbitControls.html | | Controls | https://threejs.org/docs/TransformControls.html | | Controls | https://threejs.org/docs/MapControls.html | | Controls (index) | https://threejs.org/docs/#Controls | ## Scope - **In scope:** Official addons controls usage patterns. - **Out of scope:** Full physics character motor; mobile gesture frameworks. ## Common pitfalls and best practices - Forgetting `update()` with damping enabled causes drift never settling. - TransformControls fighting with Orbit—pause one while using the other. - Pointer lock requires user gesture and exit handling. ## Documentation and version Controls are under [Controls](https://threejs.org/docs/#Controls) (Addons) in [three.js docs](https://threejs.org/docs/). API details (`enableDamping`, events) evolve—link `OrbitControls` / `TransformControls` pages for the user’s three.js version. ## Agent response checklist When answering under this skill, prefer responses that: 1. Link the specific controls class from the docs. 2. State `controls.update()` when damping is on, every frame. 3. Coordinate `TransformControls` with selection / **threejs-objects** raycasting. 4. Separate desktop navigation from **threejs-webxr** locomotion. 5. Call `dispose()` on controls when unmounting canvas. ## References - https://threejs.org/docs/#Controls - https://threejs.org/docs/OrbitControls.html - https://threejs.org/docs/TransformControls.html ## Keywords **English:** orbitcontrols, transformcontrols, mapcontrols, damping, camera controls, three.js **中文:** OrbitControls、轨道、TransformControls、变换控制器、阻尼、three.js
