Git and Game Development

     A subject that has always been near and dear to my heart is video games. Throughout my life I have always been deeply enamored with games and the process of their creation, from the intricacies of 3d modeling to the various game engines in use. Despite that, I would not say I am an expert in modern game development by any means. As my classes have progressed however, I have begun to understand more about the inner workings of software development and how teams are managed. This led me to investigate how game developers use these tools to manage projects and keep everything orderly. After doing some research, I found that many game engines are compatible with git and have no issue being stored on GitHub. Not only that but prominent game engines like Unreal Engine even have their source code up on GitHub, available for anyone to fork and clone. This was done to allow developers to modify the game engine itself, for whatever purposes they need. Godot is a free open-source engine that uses the MIT license and is also entirely up on GitHub. Of course, even if an engine does not have their code on GitHub or Gitlab that does not mean you cannot just host your code in an online repository. Thanks to what I have learned this semester, I can now make use of GitHub in the creation of repositories for any game projects I have. 

  It is not enough to learn about how game developers make use of git, project management is also a vital tool for game development. In terms of project frameworks, agile methodologies have seen widespread use within various industries, including the video game industry. Scrum is the most prominent of these methodologies and has been adopted by various companies. Due to the nature of video game development, there is a greater need for cross-disciplined teams comprised of developers versed in various skills. Game development can be effectively chopped up into tasks that fit nicely into each increment, for the medium itself necessitates a functioning step by step pipeline. Level designers cannot do anything without the assets created by artists and so on and so forth. The first couple sprints would work on creating functional assets like 3D models, textures, and game mechanics. The goal of each subsequent sprint would be to create a functional game section by section. I hope to one day make use of scrum and help create a game of my own.

CS-343 Week 10

GRASP (General Responsibility Assignment Software Patterns) assigns responsibilities for different modules of code in object-oriented software development. There are seven types of roles assigned to classes and objects to easily organize the responsibilities. These roles include Controller, Information Expert, Creator, High Cohesion, Low Coupling, Polymorphism, and Protected Classes. It is important to note that GRASP is occasionally paired with SOLID principles, making for the combination SOLID GRASP. Design patterns like this help keep code clean and more organized, making it more comprehensible and reusable.

Controller suggests that the entity responsible for handling a system operation should be its own class to act as an intermediary between the user interface and the logic of the program. This helps separate concerns as well as improve flexibility of the whole system. Information Expert focuses on assigning responsibilities to classes that include the most information required to fulfill them. By following this principle, we can design systems where responsibilities are distributed efficiently amongst classes which in turn reduces dependencies. Creator guides the allocation of responsibility for creating objects. A class should be responsible for creating objects of other classes if the first class aggregates or has a composition relationship with the second class. By following this, there will be less coupling between classes and ensures better maintainability. High cohesion advocates designing classes with a clear and focused purpose. Each class should have a single responsibility and capture related behaviors and data. This provides easier comprehension of the code and simpler test cases to write. Low Coupling relies on designing classes with minimal dependencies on other classes. The less interconnections between classes allows to create a more modular system and improves maintainability since changes to one class are less likely to affect other classes. Polymorphism enables objects of different classes to be treated the same throughout a common interface in object-oriented design. Leveraging this principle allows for the design of systems to be extensible and adaptable to new requirements and promotes loosely coupled systems.

Applying GRASP principles ensures a clear distribution of responsibilities and promotes low coupling and high cohesion among classes. These principles help create an understandable design architecture while also providing the ability to adapt to future changes. This also helps team members collaborate due to better facilitation for communication among developers and it establishes a common understanding of each component’s role and interactions.

Should we still use SOLID Principles?

While I was perusing for an article to write about this week I found this interesting blog post posing the question, “Why SOLID principles are still the foundation for modern software architecture”. The post is written by Daniel Orner, a Software engineer from the likes of Flipp and formerly IBM.

Daniel starts by explaining what exactly is “SOLID”, he attributes the meaning of SOLID to “the writings of Robert C. Martin in the early 2000s” which provided a framework for creating quality object-oriented programs.

Daniel then covers what has changed since the 2000s but also what hasn’t. Things that have changed are the popularity of scripting or dynamic languages has risen greatly, some facets of object-oriented programming have become meshed with functional programming, open source software has become extremely popular, and microservices have seen massive growth in use since the 2000s.

However, things that haven’t changed are that programs are still written and modified by people, there is still a form of organization/separation of code regardless of the language used, and code can be used for either internal or external purposes. I believe that all of these facets of programming may never change no matter how much time passes. Even with the advancement of AI, I still believe that the human factor in programming will always be important. When faced with potential moral or ethical problems, a human element would always result in a better outcome than an AI could/would.

Daniel then goes through each of the five principles and alters them to become more general and applicable to modern programming trends. He starts by altering the single responsibility principle to “Each module should do one thing and do it well.”, the open-closed principle to “You should be able to use and add to a module without rewriting it.”, the Liskov substitution principle to “You should be able to substitute one thing for another if those things are declared to behave the same way.”, the interface segregation principle to “Don’t show your clients more than they need to see.”, and finally he left the dependency inversion principle as is!

Daniel then wraps up his post concluding that modern SOLID is ensuring that your code is not surprising or confusing to anyone who will use or work with it, keeping things reasonable, and properly organizing said code. Reiterating that SOLID is still key to creating and maintaining well-written code.

Overall, after reading Daniel’s post it allowed me to widen my view and understanding of the solid principles. After comparing his new definitions to the ones crafted by Robert Martin, it showed how well thought out SOLID principles were to be able to last 20+ years already and remain relevant for plenty more to come. The SOLID principles offer a framework not only for object-oriented programming but programming in general and Daniel showed this impeccably just by changing a couple of words in the definitions while keeping the same meanings given to the principles back in the 2000s.

11/18 – Keeping the ball rolling.

So, since the end of the semester is coming up, I should be posting weekly for the near future, so stay tuned for a lot from me! With this week of work, I have two topics I wanted to discuss, both related to each class I’m taking with Professor Wurst.

Firstly, on the Software Process Management side, I wanted to discuss how we’re using Scrum, and the way it’s set up. We’re using GitLab’s issue boards, dividing them amongst where they currently are in The Sprint, with stuff like the Issue Backlog, In Process, Needs Review, Finished, and so on so forth.

This setup reminded me a hell of a lot of Trello, a website/service I’ve been using for years now! And what’s funny is that I even mentioned this in class once, and the Professor said he used to as well for Scrum. My setup is quite different compared to the setup we have on GitLab, however, it still uses a similar Scrum/Kanban-esque setup.

Here’s the two boards I mainly use, one for School, and one for Commission work, as I freelance in art. With my Comm board, it is a bit more simpler, having using tags within lists as opposed to using a list per tag. As for my schoolwork board, it’s simply just listed with each course I’m taking and items of work I need to finish. It’s a very good tool, and I highly suggest it to anyone looking to utilize Scrum or even need a good tool to organize things.

Check it out here! https://trello.com/

As for the Software Design, I was curious what kind of file the .json’s we were using were. We have been using them to store data about students and members of the modified version of LibreFoodPantry’s backend. I’ve seen them used before many times in my times modding games before, usually they store data for configuration files.

So, to learn more, I found this blog from HubSpot: https://blog.hubspot.com/website/json-files, and honestly I think I get it a bit more now. They’re simply data storage files, able to store comma seperated values, objects, and arrays. They also support multiple data types, like integer, boolean, and strings.

So putting that into the context of configuration files, like for settings in games, it makes sense why they are used, due to integer and boolean values. If an option for a game has an on/off choice, a boolean data value to hold that information would make sense, as “true” would be on, and “false” would be off. As for how integers would be used, say you want to store the value of the volume the user wants while playing the game, that can be stored as an integer from 0-100.

All in all, it’s really interesting to learn more about filetypes I don’t know too much about, and I should look into more and how they are written, like .obj, .html, and .ini.

Navigating Code with the Principle of Least Knowledge

I recently delved into the fascinating world of software design principles. Among these, the Principle of Least Knowledge, also known as the Law of Demeter, caught my attention and proved to be a valuable guide in crafting efficient and maintainable code. In this blog post, I’ll share my insights into this principle, drawing from various resources to shed light on its significance.

The Principle of Least Knowledge

The Principle of Least Knowledge advocates for limiting the interactions between classes or components in a system, promoting a low coupling and high cohesion design. In simpler terms, it encourages a module to only communicate with its immediate neighbors, reducing dependencies and enhancing the system’s flexibility.

Selected Resource

I stumbled upon an insightful article titled “Law of Demeter in Java”, which provided a comprehensive exploration of the Law of Demeter and its practical applications in Java programming. This resource not only clarified the concept but also demonstrated real-world scenarios where adhering to the principle can significantly improve code quality.

Why This Resource?

Choosing this resource was a no-brainer for me. The Law of Demeter seemed like an abstract concept at first, and I needed a practical guide to bridge the gap between theory and implementation. The Baeldung article not only provided a clear explanation but also offered concrete examples, making it an invaluable tool for someone eager to enhance their coding practices.

Insights and Reflections

After absorbing the content, I realized that applying the Principle of Least Knowledge fosters modular and maintainable code. By minimizing direct dependencies between classes, code becomes more resilient to changes and easier to comprehend. This is especially crucial in larger projects where codebases can quickly become unwieldy.

The real strength of the Law of Demeter lies in its ability to enhance collaboration within a development team. When each module interacts only with its immediate neighbors, team members can work on different parts of the system without constantly interfering with each other’s code. This not only boosts productivity but also minimizes the chances of unintended side effects during the development process.

Future Application

As I move forward in my studies and eventually into the professional realm, I anticipate applying the Law of Demeter as a guiding principle in my coding practices. I foresee it becoming a cornerstone in my approach to software design, ensuring that the systems I contribute to are not only functional but also maintainable in the long run.

In conclusion, my exploration of the Principle of Least Knowledge has been enlightening, thanks to the practical insights provided by the Baeldung article. Understanding and implementing this principle is undoubtedly a step towards becoming a more proficient and conscientious developer.

Using Programming Languages in VSCode

Overview

This week in class, my group and I installed Java in VSCode and created a unique file to write code in. It was the first time that I created a file that wasn’t in BlueJ or ZyBooks in order to write runnable code inside of. Being it was my first time experimenting with it, it took a while for me to understand. But once it became clear to me I found it very interesting. A tutorial on getting started with Java in VSCode I read went further into detail on how to use Java in it, covering tools, testing, project management, what needs to be installed and many other helpful things.

Installing Java

To first get started a coding pack needs to be installed. There’s a link leading to the files that need to be downloaded. However, the Development Environment activity we did in class only required that the Java devcontainer extension packs in VSCode were installed. Installing that same extension pack is actually the second step for the article’s “Hello World” example. A JDK (Java Development Kit) is vital for running Java in VSCode. With the coding packs and the JDK, Java has been successfully installed onto VSCode.

Creating Source Code Files

The part that fascinated me was creating a source code file. Since the Java coding packs and development kits have now been installed, you can create a file specifically for Java code. This is achieved by choosing a name for your file and adding “.java” to the end of it. VSCode now knows that it is a java file and will recognize any terms and symbols specific to Java that it wouldn’t if it was just a regular text file. Write down code and it won’t take you long to notice that terms like “int”, “for”, “public”, “class”, etc. are colored differently. When you are done writing your code, there should be either a play symbol or a link that says “Run|Debug”. If your code is compilable, the output of your code will be returned in the terminal. 

Interesting Features

VSCode offers many interesting tools that make it easy to search for, test, and edit code among other things. If you have a project in Java or any programming language, it is easy to sort through. On top of that, there are so many extensions such as code spell checkers, debuggers, test runners, and many other tools that make creating code that much easier. Compared to BlueJ and other IDEs I’ve used, this has been the most useful. It took a while to get the hang of, but once I did, I realized how good of a tool VSCode is and can potentially be.

Copyright Licenses

From the previous week’s we have been covering the different types of software copyright licenses and their differing purposes in the field. The blog post I chose to cover is “Understanding Software Licensing” by Fernando Galano. The goal of the blog post was to help simplify the legalities of differing software copyright licenses as well as expressing the importance of understanding copyright licenses and why you should know when to use the different kinds. From what we learned in class, from the videos as well as our in class activities, the blog post worked hand in hand in reinforcing the pros and cons of the different copyright licenses to give a better grasp on the topic.

The blog post started with what a software copyright license exactly is. Galano described the concept of a software license is the establishment of a contract between the creators of the software and the individuals who would be using it. The contract would lay out the terms and conditions that the user must follow when it comes to use of the code as well as the rights and liabilities of the user and creator. As explained in the post, the license will protect both parties and make sure that the use of the software is as intended from both the creator and user. After Galano described the preemptive information about what a license is he explained the different types and their pros and cons. He described Public Domain Licenses, Copyleft Licenses, Lesser General Public Licenses, Permissive Licenses and Proprietary Software Licenses. Each license had a almost like tldr description that allowed the reader to easily understand what each license is meant for. He ended the blog post stating that every license has a purpose and it is up to you as the creator to decide what your purpose is for the software and what you want it to be used for.

The reason I chose this blog post was due to the fact that while we have been covering copyright licenses I feel like I still didn’t fully grasp the differences and when you should use each kind of license. This blog post was perfect in using simple terms to allow me to easily understand the different kinds of software licenses and their differing uses. From this I will now be able to one hundred percent understand why I am choosing a certain license when it comes to protecting my work. I feel like reinforcing my knowledge on items like this is very important as copyright licenses are a huge part of developing software.

Designing in Git?

When it comes to software, and working on it as a team, or sharing it with others, Git appears to be the bread and butter of it. That is what class is kind of centralized around, learning how to use Git, and how it benefits you and others. At first glance, it appears very hard. However, after understanding its role in the greater scheme of things and putting it into practice, it’s not all that hard. Originally, I thought Git was another coding language, like Java or C++. I was severely wrong, as it is more similarly to Bash in a way, but unique in its own way. It allows for people to create code, share it with others online, where it can be used, changed, and reshared with the original creator or other people, where the same thing can happen, making branches of versions of code different from the last.

To use Git, you need a code hosting platform, like GitHub or GitLab, and a code editor, like VS Code. You don’t need to use these specific sites or editors, as each is similar and unique in their own way. Once you have these, you can start writing your code, stage it, commit it and push it into your code hosting platform on the internet for others to see, use and change. Or you could fork some code you see and change it up however you want, stage, commit and push it back and see what others think. Git allows not only teams to work on code together, but strangers to work on it, from all over the world. 

But who says Git can only be used for coding purposes? In this blog post, by Bruno Brito, they describe how Git can be used for designers, as in those creating graphic design and photo editing. In the post, they describe what Git is, how it is used, how to use it, and other things needed to know as a beginner to Git. However, instead of editing code, they use photo editing software. In the specific post, they are using Tower, which is similar to our VS Code. They describe how to create repos, how to stage and commit, and then how to use code hosting platforms, or for designers, cloud-based hosting platforms, to maintain synchronization. Then they go on to describe forking, cloning, pushing, pulling and branches. 

At quick glance, this could be interpreted as a tutorial for Git, which it is. But it is in a setting different from coding, specifically for design. I like this post because it shows that Git can be used for other fields, similar to my last post. I find that these ways of organizing code, among teams and many people, efficiently, and it allows many people to chip in, and upload their work. Although the post to me is essentially useless, as I have already learned how to do Git, it can be helpful to others who are looking for ways to create an efficient work environment. I can relate to this in a way, as a communications student as well, I am somewhat fond of art, and graphic design. I may not use Git if I am creating work on my own. But in a team, keeping track of who is doing what, and what changes have been made to this piece and what not, it can be helpful.

Cs-348, Cs @ Worcester Week 10

https://www.revelo.com/blog/integrated-development-environments

The in-class activity this week, we focus on VS code and other types of Integrated development environment (IDE) . I found an article explain about the definition, purpose of IDE and a list of 10 common IDEs that developers should know.

IDE is a software application that simplifies code development, testing, and debugging, aiding in organizing project artifacts. It includes tools for Java, Microsoft Visual Studio, Android Studio, RStudio, and PyCharm, and compiles and interprets programs.

IDEs aid developers in real-time code parsing, detecting human mistakes, and allowing activities without switching between programs. Most enterprise development teams choose a pre-configured IDE suited to their specific use case.

IDE simplifies the setup process for developers by integrating different tools into the same workbench, saving time and effort. This is especially beneficial for onboarding new engineers, who can learn about standard tools and workflows. IDE capabilities save time by eliminating character sequence writing.

There are 10 common IDEs which are derived from a study of how frequently IDEs’ download pages are Googled.

Visual Studio: is suitable for web, mobile, and video game development. It offers compatibility testing tools for over 300 devices and browsers, making it suitable for both students and professionals.

Eclipse: is a free, open-source editor suitable for beginners and experts, initially a Java environment. It offers Java and Plugin Development Tooling, debugging tools, and Git/CVS compatibility.

Atom: is a Linux-based hackable text editor developed by GitHub. It offers various features, including the ability to activate extensions for significant changes or make minor tweaks. It can be used for writing fiction books, Python code, technical documentation, and more.

NetBeans: is a free, open-source development environment for Java apps, offering a simple interface, project templates, and bundles for other languages.

PyCharm: JetBrains’ PyCharm is a comprehensive IDE for Python programmers, offering a free Community Edition, a 30-day trial, and an annual membership ranging from $213 to $690.

Intellij IDEA: JetBrains offers the IntelliJ IDEA IDE, which includes a free Community Edition and a 30-day trial for the Ultimate Edition, which costs between $533 and $693 a year, offering a wide range of capabilities.

Code :: Blocks: is popular free and open-source which is a versatile tool that can be customized to suit specific needs, ensuring reliable functionality across all platforms.

Aptana Studio 3: a powerful open source IDE, offers a significant upgrade over its predecessors, allowing users to design, test, and deploy web apps from a single IDE.

Komodo IDE: a popular IDE for online and mobile development, offering a simplified UI, advanced editing, and features like the Syntax Checker and single-step debugging, with a free 21-day trial.

Ruby Mine: JetBrains’ RubyMine is a popular IDE for Ruby programmers, offering simple navigation, logical workflow organization, and interoperability with most platforms.

I chose this article because it provides the information that I need to deeply understand the IDEs and pick out the most appropriate preference for my future work.
