Predatory Simulation of Animals

Demo

Description

This program simulates the predatory relationship of cats and snake with birds. Here, the birds are the prey.

• The animals move about on the window.
• Although visually it seems like a 2D space, in actuality, there are moving in a 3D space.
• Every animal has a speed with which they move.
• Every animal has a range in which the other animals may fall into.
• Birds and Snake have a smell and hear property with which they can store the animals they have smelt.
• Cats and Snakes move to the nearest bird in the plane.
• If the bird is within the range of the snake or the cat, the bird is eaten and it dissappears from the screen.
• This simulation keeps going until all the birds have been eaten.

Movement and Ranges

Cats (C)

• Range: 8
• Speed: 16

Snakes (S)

• Range: 3
• Speed: 14

Birds (B)

• Move in a random (-10, 10) along the X axis.
• Move in a random (-10, 10) along the Y axis.
• Move in a random (-2, 2) along the Z axis.

Classes

Animal class

• Its subclasses: Cat, Snake and Bird
• Superclass for other specific animal subclasses to inherit from.
• Contains shared animal attributes.
• Move method to move the birds indirectly by passing the dx, dy and dz to the Move() in Position.
• Other move methods to randomize the positions of the birds
• Methods to find the nearest bird and to check whether the otehr animal is in range
• ToString method to display their properties.
• Subclasses implement other methods to hear and smell.
• An animal hears if the other animal is travelling at a certain speed within a certain distance.
• An animal smells if the other animal is within a certain distance.
• Both hear and smell methods would store the animals in a double linked list.

Position class

• The class defines the positions of the animals in a 3D space.
• It has x, y and z attributes.
• Methods to manipulate the positions of the animals: MoveTo(), DistanceBetween(), RandomPosition(), etc.

DoublyLinkedList class

• Standard list with a few tweaks.
• A doubly linked list to store the names of the animals or the smelt/heard animals.
