    I have over 10 years of experience in Unity. I have developed 20 games so far ranging from turn based to online strategy with match making. I am experienced with Unity's event flow and have a firm grasp of the Structures and Idioms needed in Game Development. My expertise lies in multiplayer games with simple rules that yield complex interactions between users. It doesn't take me long to have a working prototype and my projects are mostly designed to work with mobile and various account systems like Steam, IOS and Google-Play. My recent project is a game called Chess Cubed which will be out on Steam and Android and IOS soon. The game was completed in 6 weeks and offers innovative game-play. This is blazing fast compared to other 3D chess variants that typically estimate 6-8 months of development time and leaves a lot more room for visual polish and Q&A. What more can I say? Apple Vision Pro developer. I also have experience in Pose recognition using Nuitrack and Azure Kinect.

    Hello, I'm a freelance game programmer with 10+ years of game programming experience, specializing in development of 2D, single-player, web browser games. I can help you build your game, starting from its inception, through the development cycles including an minimum viable product (MVP) or prototype, and finally to deploying a finished, polished product on your website. Having a game idea is easy, but being able to turn that idea into a game is the tougher challenge. You have the idea and design for your game ready, as well as your graphics and sounds effects, but the final missing piece of your game is to bring all of these together with coding. ** How I can Help You ** That missing piece is my specialty. With your design details and media, I write the code to combine it all into a fully-functioning game. I code 2D single-player, HTML5 games using the following technologies, and for the following genres: ⭐ Phaser 3 ⭐ Typescript ⭐ Platformers ⭐ Side / Top-down scrollers ⭐ Action / Arcade / Shooters / Adventure / Maze ⭐ Puzzles / Blocks / Music / Educational ⭐ Cards ⭐ Node + NPM ** Other services: ** ⭐ Converting an existing 2D single-player Flash game to HTML5 Canvas ⭐ Adobe Animate ** Also, I should point out services I don't offer: ** * Game design / UI / UX * Graphics / art * Native mobile app development (includes both Android and iOS) * Website design / development * Blockchain / Metaverse / NFT / Crypto * Gamification / Apps that are not games ** Why Hire Me? ** For starters, a game programmer/coder can be invaluable to you if: * Coding has always felt like rocket science to you; or * You can code, but don't have the time, due to addressing larger-scale challenges in your business Coders take on the burden of figuring out how your game should work under the hood. So you can focus on the bigger picture – delivering quality, engaging games to your players. ** If we were to work together, here's what we'd do: ** With your design details, graphics, and other assets, I work with you to help you build your game. The more details you can provide, the better, but I can help flesh out missing pieces from what elements your game may need, best practices, and the final deployment onto your website. 1. Press the invite button to invite me to your job. 2. We can use Upwork chat or a phone / video call to communicate further what you're looking for to determine if we're a good fit. 3. We'll discuss all the details, including how the game should function, what assets we'd need, and hosting the game on your website. Perhaps you have (or maybe are!) the designer, you have an artist, and you're looking for a programmer. If so, I'd be interested in learning more about the game you are building. If this sounds good, press the invite button, and let's find out if we're a good fit for working together to help you create your game. See you on the other side. - Cartrell.

What Is Object-Oriented Programming and Why Is It Important?

You’ve probably seen most back-end programming languages described as object-oriented programming (OOP)—so what is object-orientation in web development, and why is it important?

At its core, it’s a logic—one we use in daily life. We naturally think of things as objects with attributes and behaviors, and that determines how we interact with them. It’s interacting in the abstract, and it’s why OOP can boost speed and efficiency.

What is abstract interaction?

If you want to change the television channel from your seat, you use a remote control. That remote control is an object with a number of attributes and behaviors hidden inside of it. Without an understanding of those hidden attributes—the microchips, wiring, etc.—you still know and expect that pressing a button will perform that particular function. You’ve interacted with the remote control in the abstract, skipping the steps the remote was designed to carry out. That’s the beauty of OOP—the focus is on how the objects behave, not the code required to tell them how to behave.

So, what are objects?

A car is an example of a complex object, with many attributes. We don’t need to understand all of its internal mechanics, what kind of engine it has, how the gas makes it run, or even where the gas came from in order to know how to interact with it. The car’s behaviors have been made simple for us through object-oriented logic: put the key in the ignition, and the car turns on and gets us where we need to go. The attributes that make this possible—all of the car’s parts, electronics, and engineering—are a “package” we don’t need to break down in order to understand.

Apply this to software building, and it allows developers to break down big, complicated projects into compartmentalized objects, program them to have attributes and behaviors, then essentially set them aside and focus on programming how the objects interact—a higher level of thinking that makes writing code less linear and more efficient. Modern, high-level languages like Python and Ruby are perfect examples of OOP. The fact that they’re able to be so streamlined gets right to the heart of OOP logic.

Object-oriented programming & back-end development

What is object-oriented programming in terms of how a site is built? OOP defines most modern server-side scripting languages, which are the languages back-end developers use to write software and database technology. This behind-the-scenes, server-side technology tells a website or web application how to behave, and also builds the architecture for a site to interact with its database. That scaffolding is how data is delivered and processed, effectively making it the brain of a website. And that’s where object-oriented logic comes into play.

If a website’s brain uses object-oriented logic, it’s designed to think of data as objects. It affects how a site is built from the ground up, how data is organized, how later growth and maintenance of the site will occur, and more.

Benefits of object-oriented technology include:

  • Ease of software design
  • Productivity
  • Easy testing, debugging, and maintenance
  • It’s reusable
  • More thorough data analysis, less development time, and more accurate coding, thanks to OOP’s inheritance method
  • Data is safe and secure, with less data corruption, thanks to hiding and abstraction
  • It’s sharable (classes are reusable and can be distributed to other networks)

The building blocks of object-oriented programming

Objects are central to OOP, but they’re not the only moving part. Here’s a closer look at the other building blocks, and how they work in tandem to create back-end code that houses, moves, and manipulates data from a database into a usable web application.

  1. Objects: An object is the core unit of OOP. Objects are uniquely named and represent an instance of a class. Each object houses different states (attributes), and shared behaviors, called methods. For example, a Prius is an object in the class of “cars,” in a subclass of “hybrid cars.” Its attributes include anything from the number of doors it has to how its electric component is charged. It’s similar to other cars by its behavior—it drives—but its attributes are what set it apart.
  2. Classes: A class is a blueprint for how an object is built, as well as being a sort of “parent category” for objects. Using the previous example, a class dictates the concept of a car—four wheels, an engine, a body, brakes, etc. It allows certain set criteria to be passed down to all objects in the class. All varieties of cars behave relatively the same on a basic level, but its their attributes and methods that make them unique.
  3. Inheritance: This is an important aspect of OOP, hinted at above. By deriving classes from parent classes, behaviors can be passed down to objects, then more complicated attributes can be added the deeper you go. For example, breaking a car into subclasses (car → sports car → V8 sports car) makes it possible to layer in more features without starting from scratch.
  4. Abstraction & Encapsulation: This describes how attributes are housed and hidden within an object—including its data. Objects are designed to only reveal the necessary data, allowing software to interact with the object on a higher level. It’s equal parts security and simplicity. In the case of car parts, by safely stowing them within the body of an assembled car, things are less likely to get broken, and users can interact with the big picture: pressing the gas means go, no questions asked.

Procedural languages vs. object-oriented languages

Procedural programming (via languages like ColdFusion) is code that is broken into “procedures”—it’s a different way of thinking about how code interacts with data that’s more linear. Procedures are functional bits of code that interact with and change data, like little machines that gather input, process it, then deliver output. With OOP, however, data and functions (attributes and methods) are bundled together within the object. This prevents the need for any shared or global data with OOP, which is a core difference between the two approaches.

Traditional procedural languages like C and Pascal require you to think in terms of the computer rather than thinking in terms of the problem you’re trying to solve. For less complicated applications, procedural languages offer ease and transparency that bundled objects don’t always allow—something that can make it more difficult for programmers to analyze smaller bits of code on the tail-end of the development process.

When it comes to creating reusable components in software, OOP is the clear winner. Reusability leads to efficiency, simplifying programming and creating “shortcuts” to software design.
