State Graphs

Like State Charts but meh.

FSM-Like Concepts

State Node

• Has Unique String Id
• Exposes .enter and .exit events

Transition HyperEdge

• Sources: Ids (Exited in order)
• Events: Names and args
• Guards: Boolean Condition Expression
• Actions:
  • Send Messages to Queue
  • Set Data Values
  • Invoke Game Actions?
  • Scripted Logic?
• Targets: Ids (Entered in order)

Data

• Bools, Ints, Strings
• Trigger changing($data) event on data change attempt
  • also _in( for internal changes
  • also _ex( for external changes
• Trigger changed($data) event on data changed

Events

• Have Name snake_case
• Can use Args ($var1,$bloop)
  • Args are extracted from message or defaults
