Overview

EcoSim is an object-oriented Python project simulating a dynamic predator-prey ecosystem with graphical visualization. It demonstrates core OOP principles including inheritance, encapsulation, polymorphism, and exception handling, all built on a custom game engine using Python and Tkinter.

In this simulation, wombats and snakes interact within a 12x10 grid of land tiles (dirt and sand). Wombats graze on grass, while snakes hunt wombats. Grass spreads over dirt tiles, creating a balanced and evolving ecosystem.

Features

• Object-Oriented Design
  Implements abstraction, inheritance, polymorphism, and encapsulation across animals, plants, and tiles.

• Graphical Interface
  Uses a custom game engine built with Tkinter to render real-time simulation graphics.

• Dynamic Ecosystem
  Animals move autonomously, seek food, reproduce, and interact realistically.

• Exception Handling
  Custom OutOfBoundsException ensures animals remain within simulation bounds.

• Extensible Architecture
  Easily add new animals, plants, or terrain types following established OOP patterns.
