OOP Evolution

This is a project for a university OOP course. The requirements are detailed (in Polish) here.

Instructions

To run this program you need the com.googlecode.json-simple library which you can get from maven.

The entry point agh.cs.evolution.Main accepts a single optional argument, the path to a JSON configuration file for the simulation.

The JSON file is structured as follows:

{
    "mapSize": [100, 30],
    "jungleSize": [10, 10],
    "startEnergy": 50,
    "plantEnergy": 25,
    "moveEnergy": 1,
    "startAnimals": 25,
    "grassTurns": 50
}

• mapSize: an array of integers [width, height] that describes the shape of the map.
• jungleSize: as above, but describes the shape of the "Jungle" area, which has separate grass generation.
• startEnergy / plantEnergy / moveEnergy: Integers that describe how much energy animals start with, how much they get when they eat, and how much they lose each turn they move, respectively.
• startAnimals: An integer that describes the number of animals initially placed on the map.
• grassTurns: An optional integer value that describes how many turns the simulation will run before placing any animals on the map, this can be used to allow a bit of grass to accumulate on the map so that new animals don't starve at the start of the simulation.
