Endless runner architecture — procedural chunk spawning, lane-based or free movement, obstacle patterns, speed ramping, coin/collectible systems, distance scoring.

Hyper-casual mobile game architecture — one-tap/swipe controls, instant onboarding, short sessions, ad monetization, minimalist visuals, level progression, score systems.

Idle/clicker game architecture — big number math, offline progress, prestige/rebirth, upgrade trees, automation, currency systems, time-based rewards.

Match-3 puzzle game architecture — grid system, tile matching, cascade/gravity, special tiles, combo chains, level objectives, lives/energy system.

2D platformer architecture — tight controls (coyote time, input buffer, variable jump), level design patterns, collectibles, checkpoints, hazards, boss patterns.

Mobile puzzle game architecture — grid/board logic, undo system, hint system, level packs, star ratings, touch drag-and-drop, tutorial overlays.

RPG game architecture — stat system (base + modifiers), level/XP, skill trees, quest system, NPC interaction, turn-based and real-time combat patterns.

Top-down mobile game architecture — virtual joystick/tap-to-move/twin-stick touch movement, room transitions, fog of war, spawner patterns, wave systems, minimap.

Unity animation system — Animator controllers, layers, blend trees, state machine behaviors, root motion, animation events, Timeline.

Unity audio system — AudioMixer groups, snapshots, spatial audio, audio source pooling, compression per platform.

Cinemachine camera system — virtual cameras, FreeLook, blending, noise profiles, state-driven cameras, confiner, follow/aim behaviors.

Unity navigation — NavMeshAgent configuration, NavMeshSurface, off-mesh links, dynamic obstacles, pathfinding patterns.

Unity physics — non-allocating queries, collision layers, FixedUpdate discipline, continuous collision detection, character controllers, joints.

ShaderGraph — custom function nodes, sub-graphs, keyword-driven variants, master stack outputs, common patterns for URP effects.

UI Toolkit — UXML document structure, USS styling (CSS-like), UQuery, data binding, ListView virtualization, custom visual elements.

Event system patterns — C# events, UnityEvent, SO event channels, static EventBus. When to use each, zero-allocation patterns, memory leak prevention.

Object pooling patterns — Unity ObjectPool<T>, custom ComponentPool, warm-up strategies, return-to-pool lifecycle. Eliminates runtime Instantiate/Destroy overhead.

ScriptableObject architecture patterns — event channels, variable references, runtime sets, factory pattern, data containers. The backbone of data-driven Unity architecture.

Unity serialization rules — FormerlySerializedAs on renames, SerializeField vs public, SerializeReference for polymorphism, Unity null check (== null not ?.). CRITICAL: prevents silent data loss.

Dialogue tree patterns — ScriptableObject graph, node types (text, choice, condition, event), typewriter effect, localization-ready. Load when implementing NPC conversations.

Generic state machine patterns — IState interface, StateMachine<T>, game state management (menu/gameplay/pause), enemy AI states, hierarchical FSM. Load when implementing state-driven behavior.

Mobile optimization — tile-based GPU, ASTC textures, draw call budget (<100), thermal throttling, battery, touch input, safe areas, App Store guidelines.

DOTween animation library — sequence composition, tween lifecycle, easing, kill strategies. CRITICAL: Always kill tweens in OnDestroy to prevent leaks and errors.

Odin Inspector & Serializer — SerializedMonoBehaviour, validation attributes, custom drawers, editor windows. Enhances Unity inspector with powerful serialization and UI.

TextMeshPro text rendering — font asset creation, material presets, rich text tags, dynamic font fallback, sprite assets in text. Use for all text rendering in Unity.

UniTask async/await for Unity — zero-alloc async, cancellation tokens, PlayerLoop integration, async LINQ. Use instead of coroutines for cancellation support and cleaner async code.

VContainer dependency injection for Unity — LifetimeScope hierarchy, registration patterns, constructor injection for plain C#, [Inject] for MonoBehaviours. Lightweight alternative to Zenject.
