Space Invaders in Python

Overview

This project implements a version of the classic Space Invaders video game using Python, with a graphical interface built on Tkinter and additional libraries for image processing, sound, and keyboard input.

The game includes both a single-player mode and a local multiplayer mode, following the traditional mechanics of horizontal movement, projectile shooting, enemy elimination, defensive barricades, and level progression.

The code combines object-oriented programming, real-time animation, event handling, and graphical rendering, making it a complete example of a 2D arcade-style game developed in Python.

Project Structure

The program is organized around several classes that represent the main elements of the game.

Figura

Abstract base class used as a template for all graphical game objects.
It defines common attributes such as:

• canvas
• position
• velocity
• width and height
• image path

It also provides basic methods for loading images, moving objects, and deleting them from the canvas.

Nau

Represents the player spaceship.

Main responsibilities:

• horizontal movement
• life management
• collision detection with enemy bullets

Bala

Represents a projectile fired either by the player or by an enemy.

Main responsibilities:
