Snake is a simple game build with help of Ncurses.
Ncurses is a programming library providing an API that allows us to write text-based user interfaces in a terminal-independent manner. The package libncurses5-dev needs to be installed in order to use ncurses.
Code is simple and easy to understand.
- game.hpp - contains the main logic, initializes the board, updates the state, processes the user-input, creation & destruction of 'apple', placing next snake piece.
- board.hpp - constructs centered board for snake, adding of chars and getting input from user.
- scoreboard.hpp - initialization, display and updation of scoreboard.
- drawable.hpp - implements class which can display anything on board having x, y & icon values.
- apple.hpp - inherits drawable class and represents apple on board.
- empty.hpp - inherits drawable class and represents an empty space on board.
- snake.hpp - implements snake, its direction and gives position of next head of snake.
Dockerfile is a single stage build, while Dockerfile.multistage is a multi-stage build.
Remember: to play the game we need to run the image interactively, i.e. docker run -it <image-name>
