# Logic Reference

Every listener, gate, and executor in GDLink — what each one does, what it expects, and how it fits the larger graph. Pages are generated from the source specifications and stay in lockstep with each release.

The three categories mirror the addon's own taxonomy:

- **Listeners** detect — input, physics, state changes, signals.
- **Gates** combine — boolean logic, FSMs, custom expressions.
- **Executors** act — motion, animation, materials, UI, messages.
