Convention Guide

When designing a State Machine, you need to know the purpose. Each State Machine has a slightly different convention.

State Machine for...

Manage users workflow

• When the element name of the State Machine similar to each other:
  • Rename the state as past tense when it has the same name as event
• For the event name, the name must answer this question:
  1. What is the event? (Answer: pay)
  2. How to trigger it? (Answer: by clicking the button or hit the enter key)

Manage system processes

• Always think about how the system can recover from failure
• Usually, they use self (loop) and backward transition to recover from failure

Creating deterministic A.I

• use Behaviour Tree (HSFM & Behaviour Tree) or
• shape it as acyclic graph (no self or backward transition)

Manage resources or data

• utilize State Management library or
• rely heavily on invoking/spawning services and calling actions
