The Event System/Dev Console is a development tool that provides real-time debugging and system control capabilities. It features a command-line interface with basic commands for input handling (charinput, keypressed), system control (clear, quit), and debugging (echo, print, timescale). Built using the Subscribe and Observer pattern, it allows developers to monitor and manipulate the application's behavior during development and testing. 

The code snippet defines an EventSystem class and an EventSystemConfig struct, along with several related functions. Here's a brief explanation of the main functions: 

• SubscribeEventCallbackFunction: This function allows observers to subscribe to a specific event by providing an event name, a callback function, and optional arguments. It adds the subscription to a list. 

• UnsubscribeEventCallbackFunction: This function allows observers to unsubscribe from an event by removing the corresponding subscription from the list. 

• FireEvent: This function is used to trigger a specific event. It iterates through the list of subscriptions, finds the observers subscribed to the given event, and invokes their callback functions with the provided arguments. 

• GetAllRegisteredEvent: This function returns a list of all the registered events in the system.

The Dev Console is a powerful tool that uses the event system to enable communication between various parts of the game engine. It allows developers to monitor, control, and debug the game in real-time.

The event system acts as a central hub, allowing the Dev Console to subscribe to events from different engine systems. When an event occurs, the Dev Console can take appropriate actions, such as displaying information or modifying game parameters.

Developers can easily extend the Dev Console's functionality by subscribing to additional events and implementing custom callbacks. The Dev Console provides a user-friendly interface for interacting with the game engine during development and testing.
