Use this skill when working with Unity game engine - C# scripting, Entity Component System (ECS/DOTS), physics simulation, shader programming (ShaderLab, HLSL, Shader Graph), and UI Toolkit. Triggers on gameplay programming, MonoBehaviour lifecycle, component architecture, rigidbody physics, raycasting, collision handling, custom shader authoring, material configuration, USS styling, UXML layout, and performance optimization for real-time applications. Acts as a senior Unity engineer advisor for game developers building production-quality games and interactive apps.
Build augmented reality experiences with RealityKit and ARKit on iOS. Use when adding 3D content with RealityView, loading entities and models, placing objects via raycasting, configuring AR camera sessions, handling world tracking, scene understanding, or implementing entity interactions and gestures.

Meta XR Mixed Reality Utility Kit (MRUK) (com.meta.xr.mrutilitykit) for Unity XR development. Use when working with Scene API data (rooms, walls, floors, furniture), spawning prefabs on scene anchors, placing virtual objects in the real world, world locking to prevent anchor drift, raycasting against room geometry, generating NavMesh from scene data, environment depth raycasting for instant placement without scanning, Passthrough Camera Access (PCA), trackable detection (keyboards, QR codes), destructible scene meshes, space maps, room sharing for multiplayer, or any MR scene-aware feature.
Event-driven interactivity for Decentraland entities. Covers pointerEventsSystem, proximity events, trigger areas (enter/exit zones), raycasting, and one-shot key presses on entities. Use when the user wants clickable objects, hover highlights, proximity-based interactions, detecting when a player enters a zone, E/F key actions on an entity, or ray-hit detection. For system-level polling (held keys, WASD movement, cursor lock, InputModifier, action bar) see advanced-input. For screen-space UI buttons see build-ui.
Camera object, CameraType enum, CFrame math, custom controllers, first/third person, cutscenes, screen shake.
Use Godot 4.x physics bodies and detection in 2D and 3D: RigidBody, StaticBody, Area, and CharacterBody; collision layers vs masks; contact/overlap signals; and raycasts (RayCast nodes and direct space-state queries). Use when configuring collision layers/masks, detecting overlaps with Area2D/Area3D, applying forces to a RigidBody, or casting rays in a Godot project (.tscn with physics bodies).
Set up 3D physics in Unity 6: Rigidbody movement and forces, colliders, triggers vs collisions, layer-based collision, raycasts, and joints. Use when adding a Rigidbody, handling OnCollisionEnter/OnTriggerEnter, tuning collision layers, casting rays, or when the user mentions Unity physics, AddForce, isKinematic, or linearVelocity.
Implement Roblox physical simulation and queries with assemblies, anchoring, constraints, collision groups, CanCollide/CanTouch/CanQuery, raycasts and overlap queries, mass, impulses, forces, velocity, moving assemblies, cleanup, and network ownership. Use for Roblox collisions, hit detection, RaycastParams, PhysicsService, projectiles, vehicles, knockback, constraints, deprecated BodyMovers, unstable motion, or client-owned physics exploits.
