# Tic-Tac-Toe

Let's consider an example of a robot that runs a game of tic-tac-toe implemented on Sherpa Robot.

The robot project consists of six diagrams. To describe it step by step, this robot works as follows:

1. It starts the game by offering to choose a symbol that the user will play with.

2. It opens the game board, after which the user and the computer take turns selecting a cell to make a move.

1. **Block "Start"** (any diagram starts from this block).
2. **Block "Get Path"** allows you to find out the full path to the file. The following properties are specified for this block:

* File name (file name);
* Generate name (if the flag is set, a random file name will be generated, including the extension).

<figure><img src="https://lh7-rt.googleusercontent.com/docsz/AD_4nXeqoscEXVmxeWC6UsE9SAx1q8utQ-aFgqmAHMte70_NtN8rONyIpaT-BgSZTmfjzwX2j4I9Iu-vouw4J2TitNFbz3ZzsmPXLOD-dtWFpqq8FJG-7ILnEZQ1FGDnFW35QXde1_-9?key=8OqHXqKR2hFCRM0MvJDUmXXN" alt=""><figcaption></figcaption></figure>

4. **Block "Show Window"** allows you to create your own windows (forms) and display them in modal and non-modal mode, including asynchronously relative to the flow of the script. If a selector is specified, the coordinates of the created window will be bound to a control element in another application. The following properties are specified for this block:

* Configuration (configuration string);

5. **Block "Switch/Case"**. The switch operator compares the expression with the specified values and exits through the specified connector. If no matches are found, it exits through the "Default" connector. The following properties are specified for this block:

* Expression (the expression to compare);
* Condition 1 (if matched, it will exit through connector 1, and expression 1 will also be executed if specified. If the connector is not specified, the exit will be made by default);

* Condition 2 (if matched, it will exit through connector 2, and expression 2 will also be executed if specified. If the connector is not specified, the exit will be made by default);
* Execute expression 2 (if condition 2 is met, this expression will be executed and exit through the corresponding connector. If the connector is not connected, the exit will be made by default);

8. **Block "Condition"** checks the specified condition for truth, after which the execution of the scenario continues towards the "Yes" exit (if the condition is met) or towards the "No" exit (if the condition is not met).

The condition is written in the format: “variable” equals (==)/ greater than (>)/ less than (<) “value”.

For example: $a == “Hello”, that is, if the value of the variable $a is equal to “Hello”, then the exit is “Yes”, otherwise – the exit is “No”.

$Result > 5, that is, if the value of the variable $Result is less than 5, then the exit is “Yes”, otherwise – the exit is “No”.

In this case, the condition is set as: $IsFinal. That is, it checks for the final.

3. **Block "Condition"** checks the specified condition for truth, after which the execution of the scenario continues towards the "Yes" exit (if the condition is met) or towards the "No" exit (if the condition is not met).

The condition is written in the format: “variable” equals (==)/ greater than (>)/ less than (<) “value”.

For example: $a == “Hello”, that is, if the value of the variable $a is equal to “Hello”, then the exit is “Yes”, otherwise – the exit is “No”.

$Result > 5, that is, if the value of the variable $Result is less than 5, then the exit is “Yes”, otherwise – the exit is “No”. In this case, the condition is specified as: $UserWon. That is, it checks whether the player has won.

4. **Block "Message Window"** shows the user a modal dialog window with a specified title, text, and set of buttons. If a window with multiple buttons is used, the block allows you to write to a variable the text constant corresponding to the button pressed by the user. The following properties are specified for this block:

* Message (the text that will be displayed inside the dialog window);
* Buttons (the buttons that will be available for the user to press).
