Extraction is the first part of the new global Bolt workflow. It is the step where Bolt analyzes your existing C#/.NET codebase, including Unity, custom scripts and third-party plugins, and converts those into a set of documented unit options that can be used in flow graphs.

First, this is a terminology change:

• Unit Options Database → Extracted Database
• Unit Options Wizard → Extractor
• Build Unit Options → Full Extraction
• Update Unit Options → Incremental Extraction

The new Extractor window will:

• Combine the previous “Assemblies Options” and “Type Options” pages
• Allow extraction of an entire Namespace at once
• Allow extraction of an entire Assembly at once
• Allow extraction of an entire Type Hierarchy at once
• Run much faster thanks to multithreading and improved data formats

Improved Incremental Extraction

The current incremental extraction (“Update Units Database”) is faster than a full rebuild because it tries to preserve data that is still valid, but it has some caveats:

• The type names have to match the file name
• There cannot be multiple types in the same script file
