一覽
ECS is an architectural pattern organizing game code by data (entities, components) instead of objects (inheritance hierarchies). Enables: data-driven design, parallel processing, cache efficiency, 10-50x performance gains. Used in: Unity DOTS, Unreal, custom engines. Salary: junior ECS engineers $80-120k USD; senior architects $160-250k. Learning curve: 3-6 months to proficiency, 2+ years for mastery. Adjacent to game engine architecture, systems programming, and high-performance computing.
什麼是 ECS Architecture Game
Entity Component System (ECS) is an architectural pattern organizing game code by data rather than inheritance. Core concepts: - Entity: unique ID representing an object (player, enemy, particle)

❓ 常見問題
What's the difference between ECS and traditional OOP game architecture?
OOP: Player class inherits from Character, which has Update(). Hard to parallelize. Cache-unfriendly (scattered memory). ECS: entities are IDs, components are data (position, velocity, health), systems process components in batch. Cache-friendly, parallelizable, 10-50x faster.
Why is ECS faster?
CPUs run faster when data is contiguous in memory (cache hits). ECS stores all positions together, all velocities together, all health values together. SIMDprocessors loop through contiguous data 4-8x faster than scattered objects. Example: 10,000 enemies updated 5x faster in ECS vs OOP.
How do I design entities and components?
Entity = unique ID (64-bit). Component = data (struct with position, velocity, etc.). System = loop over entities with specific components (UPDATE position based on velocity). Keep components small and focused.
Is ECS only for games?
No. ECS works for any system with many independent entities: physics simulations, particle effects, AI, VFX. Game development popularized ECS; now used in VFX, simulations, other domains.
When shouldn't I use ECS?
Simple games (<1000 entities) may not benefit. Strongly hierarchical data (UI, narrative) is awkward in ECS. Use ECS for: complex logic, many entities, performance-critical code.
