Turtle Pong

This repository hosts the source code for the ROS turtle_pong package, which implements the Pong arcade video game for the Robot Operating System (ROS 1 Noetic) using turtlesim.

To learn how the package was created, please read the documentation.

Usage

To use the turtle_pong package, clone this repository into the src folder of your catkin workspace:

fjp@ubuntu:/home/fjp/catkin_ws/src$ git clone https://github.com/fjp/ros-turtle-pong.git

Then build the workspace with catking-tools or catkin_make and source the new package:

# catkin-tools:
fjp@ubuntu:/home/fjp/catkin_ws$ catkin build
# or use
fjp@ubuntu:/home/fjp/catkin_ws$ catkin_make
# source your workspace using the setup.bash or setup.zsh depending on your shell
fjp@ubuntu:/home/fjp/catkin_ws$ source devel/setup.bash
fjp@ubuntu:/home/fjp/catkin_ws$ source devel/setup.zsh

Finally, start roscore, run turtlesim and pong.launch:

roscore
rosrun turtlesim turtlesim_node
roslaunch turtle_pong pong.launch

Note that each of the three commands above should be executed from another terminal so that it will run in its own process.

The game can be played with the w/s keys and the up/down arrow keys to control the left and right player (turtle), respectively.
