/**
* Manages and handles all input controls for the game, including keyboard and gamepad interactions.
*
* @remarks
* This class is designed to centralize input management across the game. It facilitates the setup,
* configuration, and handling of all game inputs, making it easier to manage various input devices
* such as keyboards and gamepads. The class provides methods for setting up input devices, handling
* their events, and responding to changes in input state (e.g., button presses, releases).
*
* The `InputsController` class also includes mechanisms to handle game focus events to ensure input
* states are correctly reset and managed when the game loses or regains focus, maintaining robust
* and responsive control handling throughout the game's lifecycle.
*
* Key responsibilities include:
* - Initializing and configuring gamepad and keyboard controls.
* - Emitting events related to specific input actions.
* - Responding to external changes such as gamepad connection/disconnection.
* - Managing game state transitions in response to input events, particularly focus loss and recovery.
*
* Usage of this class is intended to simplify input management across various parts of the game,
* providing a unified interface for all input-related interactions.
