Pong Game

This is a simple pong game built using C++. There will be two players in the game "Player 1" and "Player 2". They have to hit the ball, if ball touches left wall then Player 2 won. If ball touches right wall then Player 1 won. Their score will be increased by 1 points.

How to play

You can press these keys to change the direction of the paddle.

To move Player 1 paddle :

w	UP
s	DOWN

To move Player 2 paddle :

Key	Direction
i	UP
k	DOWN

To exit the Pong Game :

Key	Direction
q	QUIT

Libraries we'll need

• conio.h : For console input and output. For windows systems you can download the file. For linux systems that file is in the repository.

  For Linux

  • uninst.h : usleep() function in linux systems, to slow down the game. usleep() function suspends execution for microsecond intervals.

  For Windows

  • Windows.h : Sleep() function in windows systems, to slow down the game. Sleep() function suspends execution for second intervals.

Other libraries are included in cpp files

To run the game

cmake .does the compiler detection, evaluates the CMakeLists.txt in the given . director and generates the build environment in the current working directory.
The cmake --build . command is an abstraction for the necessary build/make call.

To keep source code clean from any build artifacts you should do "out-of-source" builds.

run cmake :

  mkdir build
  cd build
  cmake ..
  cmake --build .

and finally run make :

  make

To run the game :

  ./game
