unity-ecs-patterns

High-performance game development with Unity's data-oriented Entity Component System, Jobs, and Burst Compiler. Production patterns for Unity's Data-Oriented Technology Stack (DOTS) including Entity Component System, Job System, and Burst Compiler. - Covers core ECS patterns including components, systems, entities, and archetypes, with practical examples for movement, spawning, damage, and inventory management - Demonstrates both simple foreach queries and explicit job scheduling with IJobEntity and IJobChunk for fine-grained parallelization control - Includes baking workflows to convert GameObjects to entities, singleton management, aspects for component grouping, and entity command buffers for deferred structural changes - Provides spatial hashing, native collections, and performance optimization techniques including Burst compilation, chunk iteration, and enableable components as alternatives to add/remove operations - Building high-performance Unity games - Managing thousands of entities efficiently - Implementing data-oriented game systems - Optimizing CPU-bound game logic - Converting OOP game code to ECS - Using Jobs and Burst for parallelization - Use ISystem over SystemBase - Better performance - Burst compile everything - Massive speedup - Batch structural changes - Use ECB - Profile with Profiler - Identify bottlenecks - Use Aspects - Clean component grouping -...
