<-- Coding Conventions
ChangeLog -->

Converting to MVC Design Pattern.

Model Manages data and logic.

  • Defines what the app should contain.
  • Notifys view. View handles layout and display.
  • Defines how app data should be displayed. Controller routes commands to the model and view parts.
  • Contains logic that updates the model and or view in response to input from users.

Need to seperate out the different elements of the code. Implement some interfaces that layout the functions that I will need for each of the MVC elements.

What should go in:

Model

  • Initialise function to start the game?
  • hasFinished function to see if the game is over or not.
  • setFinished function to change if the game is finished.
  • restart function to restart the game.
  • getScore to get the score of the game.
  • setScore to set the score of the game.
  • getLength to get the length of the snake.
  • setLength to set the length of the snake.
  • incrementLength to add one to the length of the snake.
  • getHeight to get the dimension of the screen.
  • getWidth to get the dimension of the screen.
  • setHeight to set the dimension of the screen.
  • setWidth to set the dimension of the screen.

View

  • getMusic to get the currently playing song.
  • setMusic to set the currently playing song.
  • playMusic plays current song.
  • loadFrame function from MyFrame.
  • drawBody to draw the snake to the screen.
  • paint function to draw the screen.

Controller

  • move to move the snake.
  • isMoving to check if the snake is moving and in which direction. Could assign some constants EG LEFT = 0, RIGHT = 1... to make it easier to understand what is happening here.
  • eatBody (needs rename) to check if the snake eats itself.
  • outOfBounds (needs rename) to detect if the user has gone off of the screen.
  • KeyPressed functions...
