Pygame module must be installed prior to running airHockey.py
Read the instructions below to install pygame.

Windows Installation :

py -m pip install pygame --user

Mac & Debian/Ubuntu/Mint Installation:

sudo apt-get update && sudo apt-get install python3-pygame

Mac Compiling from Source:

brew install mercurial

*Note : If running into errors installing pygame on Mac with the first method, please refer to the buliding from source code method

**Note : Some installations of Linux may require running pygame code with Python2 instead of Python3

Intro Air Hockey

Description:

This project is a simulation of the Air Hockey game. We have used the
pygame module for the implementing this game. It has a striker for the
player, a computer that runs on its own and a puck that is pursued by
both the striker throughout the game. The objective of the game is to
make as many goals as you can in three minutes. The one who scores the
most wins!

Design:
Classes:

1. Class Background:
   This class instantiates a background for the display. Here the back
   ground is the image of an air hockey table.
   It has no methods
2. Class Scores:
   This class is designed to display scores on the hockey table
   during a game.
   Methods:
   def scoreUpdate:
   this method updates the scores during the game
3. Class Timer:
   this class keeps track of the time during the game. Eacj game
   lasts for three minutes. It has an update method.
4. Class Puck:
   This is class that deals with puck of the game. It has all its
   relevant variables like angles, speeds, scores instantiated in the
   init function.
   Methods:
   def calcNewPos:

    Caluclates the new position of the puck for every frame 

   def update:

    this updates the position of the puck using the calcNewPos 
    method
    It also handles the odd movements of the puck when it 
    collides with the edges of the display. 

   def courtHalf:

    This keeps track of which half of the court the puck is on

5. Class Player:
   This class deals with the interaction of the player in the game. It
   allows the player to move his striker with the aid of the mouse
   controller. It also handles the collisions with puck.
   Methods:
   def start:

    places the player in the correct half of the court 

   def moveMouse:

    helps the player to use the mouse as a controller in the 
    game 

   def update:

    updates the position of the player. It also handles the 
    odd parts like interaction with the walls and obstructing 
    movement into the computers half 

6. Class Comp:
   This class deals with the interaction of the computer striker in the
   game. The computer follows the movement of the puck and tries to
   score in the on the player’s half
   Methods:
   def start:

    places the computer in the correct half of the court

   def calculateNewPos:

    this method is the logic behind the computer method to 
    follow the puck. It uses basic trigometry. 

   def update:

    this updates the position of the computer. It also handles the 
    odd interaction of the computer with the edges of the 
    screen 

Testing and Modfications needed:

We have tried our code numerous times are there still are a lot of issues with the
collision between sprites. The collisions could be made more realistic using
physics momemtum laws. For now we have used basic trigonometry and vector math to
define the movement of the puck after collisions.
