Pac-Man Game Review

Pac-Man, a game loved by many, has caught the Attention of the code reviewer in this installment of the code review series. The objective of this review is to assess the object orientation and proper usage of objects within the game, identify areas where optimization can be implemented, and provide insights into code organization and GitHub practices. The reviewer also points out some common mistakes made in header file usage and class declarations, offering suggestions for improvement.

Object Orientation and Usage

One of the first aspects the reviewer addresses is the issue of putting all the source code into header files. While acknowledging that this approach may come from a background in languages like C# or Java, where the concept of header files is not present, the reviewer emphasizes the importance of separating the declaration and implementation of classes. They suggest creating separate implementation files and including the corresponding header files for proper code structure and organization.

The reviewer also highlights the inconsistent naming conventions observed in the code, urging the developer to maintain consistency throughout the project. Additionally, they encourage the use of enum class instead of plain enum for improved Type safety and readability.

Optimal Performance and Optimization

Another topic tackled by the reviewer is the architecture of the game and its effect on performance. The code reviewer draws attention to the fact that the entire source code has been included in a single file, resembling a Unity build. While acknowledging that this approach might speed up build times, they advise against it and recommend breaking the code into smaller, modular files organized in a Meaningful directory structure. This not only facilitates code maintenance but also ensures better separation of concerns and easier collaboration.

Code Organization and GitHub Usage

The reviewer expresses concern over the lack of header guards in the code, as they are essential for preventing issues related to multiple inclusion of header files in a translation unit. They suggest adopting the use of #pragma once for header protection and incorporating proper include directives throughout the project.

Regarding code organization on GitHub, the reviewer highlights the importance of not storing compiled code or ZIP archives in the repository. They recommend using a version control system such as Git, along with visual tools like GitHub Desktop or Fork, to manage project files more effectively.

Header Files and Class Declarations

The reviewer delves into the structure of the header files and offers guidance on the best practices for header file usage. They explain the purpose of header files in containing class declarations instead of definitions and suggest separating the class implementation into separate source files.

The reviewer also suggests using proper encapsulation techniques, such as making member variables private and declaring functions as inline or static as needed. They highlight the significance of including the necessary header files to ensure the correct compilation of the code and avoid undefined references.

Game Loop and Main Function

The game loop, an essential part of any game, receives attention from the reviewer. They recognize the need for simplifying the main loop to make it more readable and understandable. The review proposes moving the main loop functionality into a separate function called "run" within a game class. This allows for better separation of concerns and easier extension of functionality in the future.

Furthermore, the reviewer advises adding a check for the "quit" event and breaking out of the loop immediately if it is detected. They point out that the Current implementation processes unnecessary code even when the application is about to quit.

Rendering and Game Logic

Rendering and game logic are crucial components of any game, and the reviewer makes several observations in this area. They question the reasoning behind clearing the screen every frame, as it may result in unnecessary repainting of the same game board. The review suggests changing the logic to retain the game board when rendering is not required.

The reviewer also comments on the presence of deep nested if statements, which can lead to spaghetti code. To address this, they propose utilizing a state machine to encapsulate the different game states and transitions, simplifying the code structure and improving readability.

Conclusion

In conclusion, this code review has touched upon various aspects of the Pac-Man game's code, identifying areas for improvement and suggesting techniques for optimization and code organization. By implementing the review's recommendations, the developer can enhance the game's performance, maintainability, and overall quality.


Pac-Man Game Review: Optimizing Code Structure and Performance

Pac-Man, a classic retro game, has inspired developers to Create their own versions. In this code review, we'll analyze a particular Pac-Man clone and provide recommendations for optimizing the code structure and enhancing performance.

Object Orientation and Usage

It's crucial to ensure proper object-oriented design and usage in any project. In this Pac-Man clone, we'll evaluate the utilization of objects and their adherence to object-oriented principles. We'll focus on class declarations and implementations, Cohesive naming conventions, and the appropriate use of enums and enum classes.

Code Organization and GitHub Usage

Maintaining a well-organized codebase is essential for collaboration and long-term project maintenance. We'll inspect the code organization in the Pac-Man clone and suggest improvements, such as separating header and source files, utilizing header guards, and adopting effective directory structures. Additionally, we'll address GitHub practices, emphasizing the need to avoid storing compiled code and ZIP archives in repositories.

Game Loop and Main Function

The game loop is the heart of any game, responsible for its continuous operation. In this review, we'll assess the game loop's implementation, proposing ways to simplify and improve its structure. The goal is to enhance readability and maintainability, as well as handle events and quitting the game efficiently.

Rendering and Game Logic

Rendering and game logic play a crucial role in creating an immersive gaming experience. We'll analyze the rendering process in the Pac-Man clone, evaluating the decision to clear the screen every frame and suggesting more efficient alternatives. We'll also examine the game logic, including the handling of animations and the presence of deep nested if statements, which can be refactored for better code maintainability and readability.

By addressing these aspects of the Pac-Man clone, we aim to optimize the code structure and improve its overall performance. With careful implementation and adherence to best practices, developers can create a more efficient and enjoyable gaming experience.
