Block Reference

About This Reference

This page is a first-pass reference for the current block surface of the Flow Graph Editor. It is organized by the same broad families used by the editor palette.

The descriptions here are intentionally short. Their purpose is to help you identify the right block quickly, not to replace the runtime Flow Graph documentation.

For deeper write-ups on the largest authoring families, continue with Event Blocks, Control Flow Blocks, Animation Blocks, Physics Blocks, Audio Blocks, Data Access Blocks, and Utility Blocks.

Keeping This Reference Fresh

This page should evolve together with the palette.

• Add new blocks as they land in the editor.
• Keep descriptions short and behavior-oriented.
• Split very large families into dedicated pages if a family outgrows a single section.
