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.

The file

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 1 is distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Animation loop: when enableDamping, call controls.update() each frame.

    line 31
  2. Distinctive:

    When answering under this skill, prefer responses that:

    line 64
  3. Very specific:

    Call dispose() on controls when unmounting canvas.

    line 70

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

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

ContextSkill
Desktop/browser camera navthreejs-controls
XR controller posesthreejs-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.

See examples/workflow-orbit-damping.md.

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 (Addons) in three.js 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.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
