SIECS Documentation

SIECS is an archetype ECS for C17 and C++20. It combines a compact C runtime with a typed C++ wrapper, contiguous component storage, cached queries, systems, relations, reflection, and optional tooling.

Getting started

• Quickstart — learn the model through one compact tour.
• Building and integrating — choose the standalone distribution or Bake.
• Cookbook — short, focused patterns for common ECS tasks.

Manuals

Read the manuals in this order if you are new to ECS:

1. ECS theory explains entities, components, tables and queries.
2. Entities and components explain data and lifetime.
3. Queries explain matching and iteration.
4. Systems explain scheduling and frame logic.

Then continue with the advanced manuals:

• Archetype storage
• Resources
• Observers
• Relations
• Inheritance
• Modules
• Designing with SIECS
• REST explorer

API reference

• C and C++ API
• API stability

All examples use the public <siecs.h> facade. The C runtime uses C17 and the typed wrapper uses C++20.
