Chapter 3 - Video 3 - Mini Game (Mind Reader)

Summary

In this tutorial, the process of creating a simple game using Python is explained, focusing on building a game where an AI predicts the user's choice of '0' or '1'. The game employs basic machine learning concepts, where the AI makes guesses based on previous user inputs. The tutorial covers key aspects like using Python libraries for the game interface, creating buttons, updating the game state, and adding progress bars for scoring. The final goal is to implement an engaging game with a simple AI and a user-friendly interface.

Takeaways

• 😀 The game being developed is a binary-based Minesweeper game, where players choose between 0 and 1, and the computer (AI) tries to predict the choice.
• 😀 The goal of the game is for the computer to guess the player's choice (1 or 0) correctly. If it does, the computer earns a point; if it doesn't, the player earns a point.
• 😀 Python is used to develop the game, with libraries like `Hivi`, `Widgets`, and machine learning tools like `pkcsm` integrated into the process.
• 😀 The game’s interface involves creating two buttons for the player to select either 0 or 1, and a scoreboard displayed using progress bars for both the player and the computer.
• 😀 Two key functions are created: one to handle the player's button selections (0 or 1) and another to update the game based on these inputs.
• 😀 A system is built to calculate probabilities based on the history of the player's choices, which is then used by the AI to predict the player's next move.
• 😀 The player's choice history is stored in a list, which is used to calculate the probability of the next number (either 0 or 1).
• 😀 The game stops when either the player or the computer reaches a score of 10. Once the game ends, a message (win or lose) is displayed, and the buttons are disabled.
• 😀 The program includes a section where the game’s visual layout is structured in boxes (`vbox`, `hbox`) to neatly arrange the buttons and scoreboard.
• 😀 For added clarity, an additional file is created to provide a more polished user interface, which can be run separately to start the game.
• 😀 The AI component of the game uses basic probability to predict the player's next choice based on their previous selections, mimicking a simple form of machine learning.

Q & A

What is the main focus of the script?

The script describes a tutorial on how to create a simple game, inspired by Minesweeper, using Python. It incorporates basic machine learning for an AI-based game opponent that guesses the player's choices.

Which Python packages are required to build the game?

The script mentions the need for two main Python packages: 'Hivi Widgets' for the graphical user interface and 'mimpi' for implementing machine learning functionalities.

What is the goal of the game being created in the tutorial?

The goal of the game is for the player to choose either a 0 or 1. The computer (bot) then guesses the player's choice using artificial intelligence. Points are awarded based on whether the computer guesses correctly or not, with the first to reach 10 points winning.

How does the AI (bot) make its guesses in the game?

The AI uses basic probability based on the player's history of choices (1 or 0). The bot calculates the likelihood of the player choosing a particular number and makes its prediction accordingly.

What happens when the user clicks one of the buttons in the game?

When the user clicks either the '0' or '1' button, the game updates by storing the player's choice and triggering the AI to guess the choice. The game's score is updated based on whether the bot's guess was correct.

How is the score displayed in the game?

The score is displayed using two progress bars: one for the user and one for the computer. These progress bars are updated whenever the player or the bot scores a point based on the correctness of their choices.

What happens if either the player or the computer reaches a score of 10?

When either the player or the computer reaches a score of 10, the game ends. A message indicating whether the player won or lost is displayed, and the buttons become disabled to prevent further interaction.

What method is used to disable user input after the game ends?

Once the game ends, the input buttons (0 and 1) are disabled so that no further selections can be made, ensuring the game cannot continue until the program is restarted.

Why is the game being implemented in Python with machine learning?

The game is implemented in Python to demonstrate the simplicity and power of creating games using Python's capabilities, particularly for implementing machine learning to enhance the game's interaction through AI-based predictions.

What kind of error occurs during the development, and how is it fixed?

An error occurs when the update game function is not yet defined. This results in the game not properly updating the score or logic when the user selects an option. The error is fixed by defining the update game function and ensuring that the game logic runs smoothly.
