| 3 | This document outlines the Finite State Machine infrastructure inherent to the Player Character. It contains and defines: | ||
| 4 | |||
| 5 | * Player States & Overarching Architecture | ||
| 6 | * State Transitions | ||
| 7 | * State Actions | ||
| 8 | |||
| 9 | The player's Finite State machine defines the states and capabilities of the Player Character within the game. Each state is self-contained, and can be transitioned to when certain conditions are met. The state capabilities, transition requirements, and relations to one another are defined within this document. | ||
