nutetris

Tetris game clone written in modern c++ and ported in Java, C# and BASIC (for nuBASIC interpreter).

Why nuTetris?

nuTetris is a good sample of not trivial application which can be used as example in a programming training course. It has been designed mainly for educational purposes for developers that can deal with a non-trivial example of object-oriented design, which relies on effective modern techniques for producing modular and reusable and multi-platform code.

The game components

• Game manager
  • Builds other game components
  • Gets any input event from Input Manager
  • Executes the game state machine
  • Calls the Renderer in order to draw the game scene
  • Canvas and Game Board are instance of Grid class, which manages the interactions of piece and board. It is also used to represent the piece canvas which shows a preview of next falling piece.
  • Game data object holds information passed to the Renderer which use them to draw the scene

• Renderer

  • Interface for the game scene renderer.
  • At compile time is selected one of the following renderer implementations:
  • Text Renderer (is a Renderer)
  • Renders the game scene using ASCII art graphics
  • GDI Renderer (is a Renderer) relies on GUI (tetris::gui_t) which provides an Adapter for Linux (X11) and Windows implementations

• Piece Factory

  • Creates each Tetris Piece instance needed by Game Manager

• Tetris Piece

  • Holds piece shape information

• Input Manager

  • Manages the input devices (Keyboard, Timers). Used by Game Manager to collect any user and timer events

• Input Device (c++ implementation only)

  • Interface implemented by the actual input devices

• Keyboard Input Device is an Input Device (c++ implementation only)

  • Read and process the keyboard events
