Who Asked?

A small terminal simulation with event-driven programming

“I moved!”
“Who…?!”
“Me!”
“…Who asked?!”

Welcome to Who Asked?, a small terminal-based simulation designed to demonstrate event-driven programming in Python. The project is a study tool created to help understand how an event-driven architecture could be implemented in a simple game-like environment.

This program simulates a game world where players and enemies move around a grid, interacting through events triggered by actions like movement or collisions. The system is built around the principles of event-driven programming, which means that the game reacts to events, with each event triggering a response from listeners.

About the Code

This code was originally written in 2019 as a learning project. I recently translated it from Portuguese to English and refactored it to improve readability and security. The goal of this project was to understand how an event-driven architecture could work in Python, using a basic game as an example. While refactoring, I tried to preserve the original structure and logic of the program to maintain its educational purpose.

How it works

In Who Asked?, events like player movement or enemy actions trigger certain changes in the simulation. The event-driven nature of the game allows for dynamic behavior where actions are only taken when specific conditions are met.

Key Parameters

The game includes several parameters to adjust the game’s settings and difficulty:

• Enemies count: Defines the number of enemies in the game.
• Map width: The width of the playing field.
• Map height: The height of the playing field.
• Survival Factor: This parameter affects the overall difficulty of the game. A higher value makes the game easier, while a lower value increases the difficulty. It's not a direct “chance to win” but rather a factor that influences the player’s chances of surviving or succeeding.
• Sleep time: The time between game updates, controlling the speed of the game.

How to Run

To run the simulation, execute the following command in your terminal:

python game.py <enemies_count> <map_width> <map_height> <survival_factor> <sleep_time>

For example:

python game.py 10 10 10 50 250

This will start the game with 10 enemies, a 10x10 map, a survival factor of 50, and a game speed controlled by a 250 millisecond interval.

Feel free to fork, modify, or experiment with the project as you like. This project is meant for learning purposes and to demonstrate how event-driven programming can be applied in a simple, game-like scenario.
