This is the first laboratory work using ROS.

• I have the third variant, so I made a Squid Game prototype.
• The game receives the following symbols as input: 'l' and 'r'.
• If the symbol is similar to a certain symbol of the path, the game returns "Good choice... Let's go to the next one!" and the path that you have made.
• If the symbol is not similar to a certain symbol of the path, the game returns "You are dead" and shuts down the server node.
• All right messages are saved in "game_topic" topic.
• If the path that you have made is similar to the game path, you will receive the message: "You won, little piece of shit!..".

1. Clone this project.
2. Go to your project directory.
3. Build the project using

   catkin_make

4. You must have a roscore running in order for ROS nodes to communicate. It is launched using the following command

   roscore

1. Go to your project directory.
2. You need to run setup.bash file to add environment variables to your path to allow ROS to function. Run in with the next command

   source devel/setup.bash

3. Run the server that will process your requests. Use this command

   rosrun first_laboratory_work subscriber

1. Use this command to see messages in the topic

   rostopic echo /game_topic

1. Use this command to call the service to play the game

   rosservice call /path_to_win "turn: ''"

   You have to input your variant of the turn variable in single quotes that are underlined. You have to use 'l' / 'left' or 'r' / 'right'.
