CMU 15-110: Principles of Computing
2d Board Games

---

In class today, we will review board-game-starter-code.py and then board-game-basic-example.py.

Some vocabulary:

• This is an example of the MVC (Model-View-Controller) design pattern
• Model: the values in data and the code to manipulate that data
• View: the code to present or view the model to the user (in our code, in drawAll)
• Controller: the code to respond to events by updating the model (in our code, in keyPressed, mousePressed, timerFired, and init)

In the starter code, you should understand and use (but not necessarily write from scratch):

• These classes:
  • Cell
  • Bounds
  • BoardGame
• This function:
  • make2dList

And you should be able to understand and write (from scratch):

• These functions:
  • getCellBounds (and why it is aka modelToView)
  • getCell (and why it is aka viewToModel)

In addition, in the basic example, you should be able to understand and write from scratch:

• The Model:
  • data.boardGame -- why it is a BoardGame instance and how it is used.
  • data.boardGame.board -- why it is a 2d List and how it is used to store the cells, and the counts inside each cell.
  • data.selection -- why it is a Cell instance and how it is used.
• The View:
  • drawAll
• The Controller:
  • init
  • keyPressed
  • mousePressed
