Downturn

Chanik Bryan Lee

Downturn is a variation on Connect 4 such that board rotations are allowed and gravity is assumed on the pieces (they fall to the bottom-most available row). The idea of the game is by Professor Wachs at UChicago.

• Uses ASCII characters for board display in the shell

- `make clean` to remove all executables

Files:

• board.c/board.h: Board data structures, layout
• logic.c/logic.h: Moves logic
• pos.c/pos.h: Piece position logic/implemntation
• play.c: Gameplay logic for command-line interface
• evidence.c: Unit tests
• Makefile: To compile the executable
• README.md: This file

Set-up:

• make downturn to create the executable, called downturn
• ./downturn to run the executable with additional flags:
  • -w <width> -h <height> -r <run> where <width>, <height>, and <run> should be replaced with integer values
    • <width> specifies board width, <height> specifies board height, and <run> specifies the number of pieces in a straight line needed to win (as in Connect 4)
  • Additionally, you must add -m (matrix) or -b (bits) flags to specify whether you want to run downturn in the matrix or bits implementation
• Black starts first. At the prompt, specify a column number to drop a piece into that column.
  • In ASCII, black is represented by character * and white is represented by character o
• Or, you can rotate the board counterclockwise with <, clockwise with >

Tests:

• make tests to make an executable with unit tests, called tests
• Run it with ./tests

Other:

• make or make all to compile both downturn and tests executables
