Building high-performance Unity games with Entity Component System and DOTS. Building games with thousands of similar entities (bullets, particles, NPCs) When MonoBehaviour performance is not enough Need for data-oriented design and cache-friendly code Large-scale simulations or strategy games Keep components small and focused: Systems operate on entities with specific component combinations: Keep components small — single responsibility Avoid managed references in components (use Entity references) Use Burst for math-heavy jobs Batch entities by shared components for rendering Profile with Unity Profiler — measure before optimizing Forgetting to mark jobs with [BurstCompile] Using foreach instead of IJobEntity for large datasets Creating too many systems — group related logic Not disposing NativeArrays and other native containers
