0 - Introduction
This document outlines the Finite State Machine infrastructure inherent to the Player Character. It contains and defines:
- Player States & Overarching Architecture
- State Transitions
- State Actions
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.

1 - Core Concepts
There are 4 key concepts inherent to the FSM
| Concept | Definition |
|---|---|
| State | The different, distinct, and self-contained conditions the PC can be in. The PC can only be in one state at any given moment. |
| Action | Describes the different actions, mechanics, and elements the player can engage with.Multiple States can have access to the same Actions. Some Actions will Transition from the current State to a new one. Actions can induce Statuses on the player. |
| Status | Describes an external effect (e.g. buff/debuff) that affects the player (e.g. Blindness, Crippled) Statuses can affect the capabilities of the player (e.g. reduce speed), and prevent or allow certain Actions taking place (e.g. no sprinting when Crippled). Statuses can prevent or allow the player's Transitions to another State. |
| Transition | A Transition refers to the act of moving from one State to another, usually as a result of an Action or Status. |
2 - Player States
| State | Description |
|---|---|
| Idle | Default player State. Allows for most of the movement and combat actions the player can partake in. |
| Controlled Fall | The player is mid-air, but maintains control over the PC. |
| Freefall | The player is mid-air, but has lost control over the PC. |
| Skating | The player is skating on top of a rail. |
| Rock Climbing | The player is clung onto a climbable rock surface. |
| Rope Climbing | The player is currently on a climbable rope. |
| Grappling | The player is currently utilizing a Grapple Hook tool. |
| Mounted | The player is mounting a vehicle/ridable mob. |
