#javascript coroutines

[piratesexmachine420]

Expanding and cleaning up on a conversion I had with @suntreehq in the comments of this post:

Ruby is fine, I'm just being dramatic. It's not nearly as incomprehensible as I find JavaScript, Perl, or Python. I think it makes some clumsy missteps, and it wouldn't be my first (or even fifth) choice if I were starting a new project, but insofar as I need to use it in my Software Engineering class I can adapt.

There are even things I like about it -- it's just that all of them are better implemented in the languages Ruby borrows them from. I don't want Lisp with Eiffel's semantics, I want Lisp with Lisp's semantics. I don't want Ada with Perl's type system, I want Ada with Ada's type system.

One of these missteps to me is how it (apparently) refuses to adopt popular convention when it comes to the names and purposes of its keywords.

Take yield. In every language I've ever used, yield has been used for one purpose: suspending the current execution frame and returning to something else. In POSIX C, this is done with pthread_yield(), which signals the thread implementation that the current thread isn't doing anything and something else should be scheduled instead. In languages with coroutines, like unstable Rust, the yield keyword is used to pause execution of the current coroutine and optionally return a value (e.g. yield 7; or yield foo.bar;), execution can then be resumed by calling x.resume(), where x is some coroutine. In languages with generators, like Python, the behavior is very similar.

In Ruby, this is backwards. It doesn't behave like a return, it behaves like a call. It's literally just syntax sugar for using the call method of blocks/procs/lambdas. We're not temporarily returning to another execution frame, we're entering a new one! Those are very similar actions, but they're not the same. Why not call it "run" or "enter" or "call" or something else less likely to confuse?

Another annoyance comes in the form of the throw and catch keywords. These are almost universally (in my experience) associated with exception handling, as popularized by Java. Not so in Ruby! For some unfathomable reason, throw is used to mean the same thing as Rust or C2Y's break-label -- i.e. to quickly get out of tightly nested control flow when no more work needs to be done. Ruby does have keywords that behave identically to e.g. Java or C++'s throw and catch, but they're called raise and rescue, respectively.

That's not to say raise and rescue aren't precedented (e.g. Eiffel and Python) but they're less common, and it doesn't change the fact that it's goofy to have both them and throw/catch with such similar but different purposes. It's just going to trip people up! Matsumoto could have picked any keywords he could have possibly wanted, and yet he picked the ones (in my opinion) most likely to confuse.

I have plenty more and deeper grievances with Ruby too (sigils, throws being able to unwind the call stack, object member variables being determined at runtime, OOP in general being IMO a clumsy paradigm, the confusing and non-orthogonal ways it handles object references and allocation, the attr_ pseudo-methods feeling hacky, initialization implying declaration, the existence of "instance_variable_get" totally undermining scope visibility, etc., etc.) but these are I think particularly glaring (if inconsequential).

Find the Top 5 Latest Mobile App Development Software in 2025 — Expert Picks by TimD — Tim Digital

Choosing the right mobile app development software in 2025 is more than just a technical decision — it’s a strategic advantage. With the growing pressure to deliver faster, reduce bugs, and maintain UI consistency across devices, developers and companies alike are re-evaluating their tech stacks.

Why the Right Mobile Development Stack Makes All the Difference

Many development teams struggle not because of a lack of skill but due to poor tooling and platform fragmentation. Common issues include:

Too much time spent on duplicate codebases

Difficulty managing bugs across platforms

Low design consistency between iOS and Android versions

A better stack can lead to faster time-to-market, fewer bugs, and improved collaboration across teams.

Snapshot: 5 Game-Changing Mobile Development Frameworks

In 2025, five standout mobile development frameworks are leading the way.

Flutter, backed by Google, offers hot reload, expressive visuals, and UI consistency — making it ideal for cross-platform UI precision. React Native, developed by Meta, is JS/TS-based and features fast refresh and a robust plugin ecosystem, best suited for teams transitioning from web to mobile. .NET MAUI, Microsoft’s enterprise-grade solution, combines native speed with C# and deep integration into the Microsoft ecosystem, perfect for unified experiences across mobile and desktop. For Apple-centric development, Swift stands out with hardware-level API access and deep iOS integration, delivering high-performance, iOS-only applications. Lastly, Kotlin, Google’s preferred language for Android, is known for its concise syntax and Jetpack Compose support, making it the go-to choice for scalable, Android-first projects.

1. Flutter — Deliver Visually Consistent Cross-Platform Apps

Backed by Google, Flutter continues to lead the way for teams needing high-performance mobile apps from a single Dart codebase. With its built-in Skia rendering engine, it doesn’t rely on native UI components — giving you full control over visuals on both Android and iOS.

Why It’s a Top Pick:

Rapid UI iteration with Hot Reload

Mature ecosystem on pub.dev

Excellent for MVPs, startups, and custom-designed apps

2. React Native — A Natural Fit for Web Development Teams

Created by Meta, React Native allows JavaScript developers to build native mobile apps without switching tech stacks. It’s ideal for web teams transitioning into mobile, especially with tools like Expo simplifying builds.

Best Use Cases:

Fast deployment using React-based components

Shared codebase between web and mobile

Lightweight apps needing high iteration cycles

3. .NET MAUI — Microsoft’s Unified Solution for Desktop and Mobile

.NET MAUI enables enterprise-grade cross-platform development using C# and XAML. It compiles to native code, ensuring performance, while simplifying development for organizations already using Microsoft tools and Azure.

Why Enterprises Prefer It:

Strong support for desktop/mobile hybrid builds

Full access to native APIs

Streamlined with Visual Studio and Azure DevOps

4. Swift — The Gold Standard for Native iOS App Development

Developed by Apple, Swift is the go-to for building fluid, fast, and fully integrated iOS apps. Combined with SwiftUI or UIKit, it’s the most reliable way to deliver App Store-ready applications with deep device capabilities.

5. Kotlin — For Next-Level Native Android Performance

Endorsed by Google and developed by JetBrains, Kotlin is a modern language designed for Android. It brings null safety, concise syntax, and coroutine-based async capabilities, making it a favorite among Android developers in 2025.

Where It Shines:

Clean migration path from Java

Jetpack Compose support for UI innovation

Great for complex, scalable Android apps

Native vs. Cross-Platform vs. Hybrid — What Should You Choose?

When it comes to choosing the right development approach, your decision should align with your product roadmap, team capabilities, and performance expectations. Native development offers the best UX quality and strong scalability, making it ideal for performance-intensive apps — but it comes with higher maintenance needs and moderate development speed. Cross-platform frameworks like Flutter and React Native strike a balance by allowing faster development, lower maintenance, and good scalability, although UX quality may slightly lag behind native builds. On the other hand, hybrid frameworks such as Ionic are fast to develop and easy to maintain but offer limited user experience and only moderate scalability — making them suitable for basic MVPs or internal tools where performance is not critical.

Expert Tip: If your app relies on camera, AR, or sensors — go native. For time-to-market and design parity, cross-platform tools like Flutter or React Native offer the best ROI.

What to Look for in Mobile App Development Platforms

When selecting mobile development tools in 2025, top agencies and development teams recommend looking for:

Real-time debugging and emulation support

Comprehensive UI libraries

CI/CD compatibility (e.g., App Center, GitHub Actions)

Easy deployment to Play Store and App Store

Third-party plugin support for maps, payments, authentication, etc.

Top 5 Programming Languages & Frameworks for Mobile App Development

Mobile app development has become an integral part of our lives, with nearly every aspect of daily living influenced by the apps on our smartphones and tablets. As the demand for mobile apps continues to rise, developers are constantly seeking the best tools and technologies to create robust and user-friendly applications. Choosing the right programming language and framework is crucial in this endeavor, as it can significantly impact the development process and the ultimate success of the app. In this article, we will explore the top five programming languages and frameworks for mobile app development in 2023.

Swift (iOS)

When it comes to developing mobile applications for Apple's iOS platform, Swift is undoubtedly the go-to programming language. Introduced by Apple in 2014, Swift has quickly gained popularity among iOS developers for several reasons.

Advantages of Swift

Performance Swift is known for its high performance and speed. It was designed with a focus on optimizing app performance, which makes it an excellent choice for resource-intensive applications. Its performance is often superior to Objective-C, the language it was designed to replace.

Safety Swift comes with built-in safety features that help developers write more reliable and bug-free code. Features like optionals and type inference reduce common programming errors and make debugging easier.

Ease of Learning Swift's syntax is concise and user-friendly, which makes it easier for developers to learn and work with. This can lead to faster development times and fewer coding errors.

Interoperability Swift is designed to work seamlessly with Objective-C, which means that developers can use Swift in projects that involve legacy Objective-C code.

Active Community Swift has a growing and active developer community, which means that developers have access to a wealth of resources, libraries, and third-party tools.

Frameworks for Swift

To complement Swift, there are several frameworks available for iOS app development:

UIKit The traditional UI framework for iOS app development. SwiftUI A newer and more declarative framework for building user interfaces in Swift. SpriteKit A framework for building 2D games. ARKit For augmented reality app development.

Kotlin (Android)

For Android app development, Kotlin has emerged as the preferred programming language. It was officially endorsed by Google in 2017 as a first-class language for Android development, and since then, it has gained widespread adoption in the Android development community.

Advantages of Kotlin

Conciseness Kotlin's syntax is concise and expressive, which leads to less boilerplate code and a more enjoyable coding experience.

Interoperability Kotlin is fully interoperable with Java, allowing developers to leverage existing Java libraries and gradually migrate their projects to Kotlin.

Safety Similar to Swift, Kotlin also focuses on safety. It provides features like null safety and type inference to reduce runtime errors.

Extensions Kotlin allows developers to add new functions to existing classes without modifying their source code. This feature, known as extension functions, simplifies code maintenance and enhances readability.

Coroutines Kotlin provides built-in support for coroutines, making it easier to write asynchronous and concurrent code.

Frameworks for Kotlin:

In addition to Kotlin, Android developers can utilize the following frameworks:

Android Jetpack A set of libraries, tools, and architectural guidance for building Android apps. Retrofit A popular library for making network requests. Room An ORM (Object-Relational Mapping) library for working with databases Firebase A suite of tools for building mobile and web applications, including authentication, real-time database, and cloud functions.

JavaScript (React Native)

React Native, developed by Facebook, has become a game-changer in the world of cross-platform mobile app development. It allows developers to use JavaScript to build mobile apps that run on both iOS and Android with a single codebase.

Advantages of React Native:

Cross-Platform Development: With React Native, developers can write code once and run it on both iOS and Android platforms. This significantly reduces development time and costs.

Native Performance: React Native apps are not web apps; they compile to native code, which means they offer near-native performance.

Large Community: React Native has a large and active community, which means developers have access to a vast ecosystem of libraries and components.

Hot Reloading: React Native features hot reloading, allowing developers to see the results of code changes instantly without rebuilding the entire app.

React Integration: If your team is already familiar with React for web development, transitioning to React Native can be relatively smooth.

Frameworks for React Native:

While React Native itself is a framework, there are several libraries and tools that can enhance the development experience:

Expo

A set of tools and services built around React Native that simplifies development, especially for beginners.

Redux A popular state management library for managing the app's state.

React Navigation

A library for handling navigation in React Native apps.

Dart (Flutter)

Flutter, developed by Google, has gained considerable attention in recent years as a powerful framework for building natively compiled applications for mobile, web, and desktop from a single codebase. Flutter uses the Dart programming language.

Advantages of Flutter:

Single Codebase Like React Native, Flutter allows developers to write a single codebase that works on multiple platforms, including iOS, Android, and web.

Fast Development Flutter's "hot reload" feature allows developers to instantly see the results of code changes, speeding up the development process.

Rich Set of Widgets Flutter provides a wide range of customizable widgets for building complex user interfaces.

Performance Flutter apps compile to native ARM code, delivering high performance and smooth animations.

Strong Community The Flutter community is growing rapidly, with developers creating and sharing a wealth of packages and plugins.

Frameworks for Dart (Flutter)

Flutter itself comes with a comprehensive set of libraries and widgets, but developers can also use the following libraries to enhance their Flutter apps:

Provider A popular state management solution for Flutter.

Firebase for Flutter Firebase provides a set of Flutter plugins for various features like authentication, real-time database, and cloud functions.

Java (Android)

Java has been the traditional programming language for Android app development for many years. While Kotlin has gained popularity, Java still remains a relevant choice for building Android apps.

Advantages of Java

Legacy Codebases Many existing Android apps are written in Java. For maintaining and extending these apps, Java remains a valuable skill.

Stability Java is a mature and stable language with a long history in the Android ecosystem.

Robust Ecosystem Java has a well-established ecosystem of libraries and frameworks that can be leveraged in Android development.

Resources There is a wealth of Java resources, tutorials, and documentation available for Android development.

Compatibility Java is compatible with a wide range of Android devices, making it a reliable choice for reaching a broad user base.

Frameworks for Java (Android)

While Java itself is a language rather than a framework, developers can use the Android framework and libraries to build Android apps:

Android Studio The official IDE for Android app development. Gradle The build automation tool used in Android development. Android Jetpack A set of libraries and tools that enhance Android app development.

Conclusion

In the ever-evolving landscape of mobile app development, choosing the right programming language and framework is crucial. The choice should be based on factors like project requirements, team expertise, and target platforms. Here's a quick recap of the top five programming languages and frameworks for mobile app development:

Swift (iOS): Ideal for iOS app development, known for its performance and safety features.

Kotlin (Android): The preferred choice for Android app development, offering conciseness and compatibility with Java.

JavaScript (React Native): Enables cross-platform development with a strong community and native performance.

Dart (Flutter): Known for its single codebase for multiple platforms, rich widget library, and fast development.

Java (Android): A stable and reliable choice for Android app development, especially for maintaining legacy codebases.

Ultimately, the success of your mobile app development project depends not only on the programming language and framework you choose but also on your team's skills and the specific needs of your project.

Kotlin Multiplatform

Kotlin Multiplatform is in Beta. It is almost stable, but migration steps may be required in the future. We’ll do our best to minimize any changes you have to make.

Android and iOS applications

Sharing code between mobile platforms is one of the major Kotlin Multiplatform use cases. With Kotlin Multiplatform Mobile, you can build cross-platform mobile applications and share common code between Android and iOS, such as business logic, connectivity, and more.

Check out the Get started with Kotlin Multiplatform Mobile and Create a multiplatform app using Ktor and SQLDelight tutorials, where you will create applications for Android and iOS that include a module with shared code for both platforms.

How Kotlin Multiplatform works

Code sharing between platforms

Share code among all platforms used in your project. Use it for sharing the common business logic that applies to all platforms.

Share code among some platforms included in your project but not all. Do this when you can reuse much of the code in similar platforms:

Few Things Make Easy to Use Kotlin/Native.

Jetpack Componse

Kotlin Coroutines

Asynchronous Flow

App Architecture

Material Design

Android KTX

Safer code

Support for Xcode 14.1

The Kotlin/Native compiler now supports the latest stable Xcode version, 14.1. The compatibility improvements include the following changes:

There’s a new watchosDeviceArm64 preset for the watchOS target that supports Apple watchOS on ARM64 platforms.

The Kotlin CocoaPods Gradle plugin no longer has bitcode embedding for Apple frameworks by default.

Platform libraries were updated to reflect the changes to Objective-C frameworks for Apple targets.

Kotlin/JS

Kotlin 1.8.0 stabilizes the JS IR compiler backend and brings new features to JavaScript-related Gradle build scripts:

Stable JS IR compiler backend

New settings for reporting that yarn.lock has been updated

Add test targets for browsers via Gradle properties

New approach to adding CSS support to your project

Compatibility guide for Kotlin 1.8.0

Kotlin 1.8.0 is a feature release and can, therefore, bring changes that are incompatible with your code written for earlier versions of the language. Find the detailed list of these changes in the Compatibility guide for Kotlin 1.8.0.

Kotlin for beginners you’ll learn

The Final Words

As a business owner, you must be knowing that one of the key factors that determine the success of an app is a programming language. As such, we have laid down solid cases for Kotlin to choose the one that best suits your requirements and helps you build powerful Mobile apps faster. You can also hire Mobile app developers from 9series to build future-ready native Mobile applications and accelerate your development journey like never before.

Kotlin vs Java: Which One Is Best For 2022

Through today’s blog title you must have got a hint. We will see the basic differences between Kotlin vs Java in today’s blog.

We will do all the comparisons on Java vs Kotlin.

Android app development has become a constant trend to advance any business; small or large. But the main element in Android app development that can influence your business is the programming language used to build the application.

For many, Java is their favorite choice, mainly because it is easily available. But the presence of Kotlin in the frame can weaken the confidence that a programmer has in Java.

After the introduction of Kotlin, there has been quite a lot of debate on Java vs Kotlin; which one is better, and there have been many search queries on Google like Kotlin vs Java android development, Kotlin vs Java performance, which language is good for app development in Java vs Kotlin, and so on.

Taking this into account let’s look at some of the important points on Kotlin vs Java.

All About Java

Java is the most accepted and common programming language that is defined as class-based, object-oriented, and developed with the motive to have as minimum execution dependencies as possible.

We can say that Java is a robust language and it guides the build-up of various software application OS along with new programming languages. And one of the reasons behind its brilliant performance is its features.

Java was created by Sun Microsystems. And it was named after a Java island.

Perks Of Using Java

It is multiplatform and works on every device, server, and OS.

Java has a tight security measure which reduces the chance of getting corrupt memory. It comes with a good coding base, making it robust.

Designing extensible applications in java can be done easily because of its features like reusability which makes the code even stronger.

Java has the skill of using third-party code to make programming easier.

Java is user-friendly and eliminating bugs from it is more effortless as compared to Kotlin.

The safety standard in Java is of high quality compared to Kotlin.

Its Drawbacks

The syntax in Java is a bit tough to understand in contrast to languages like Python and C++.

Some of the content can not be accessible in Java as it can be inappropriate for the device.

The openness to advancement in mobile app development is difficult.

Java shows some issues with the API designs in Android.

Programming in Java is mostly test-driven and the user has to write more codes as there is a higher chance of bugs and errors.

Java is a little more sluggish than other programming languages and demands good device memory.

All About Kotlin

Kotlin was introduced in February 2016 by JetBrains. Analytically, Kotlin is an open-source programming language and runs on the JVM. It is the official language for developing mobile Android applications.

Kotlin splits into Java byte code for additional compilation. There are many features in Kotlin that make it different from Java.

Perks Of Using Kotlin

Kotlin app development takes very little time for code compilation and prevents the application from taking extra space.

The codes in Kotlin are smaller in size, so it has fewer bugs and errors, which makes debugging simpler.

A bytecode, which is assembled by Kotlin can be carried out with JVM. Thus, the Java libraries can be made to run in Kotlin oriented projects.

Kotlin framework is generally used for composing projects in the Android studio for auto-completion and also minimizes the error detection time during assembling.

The Kotlin is stable against Null Pointer Exception.

Kotlin embodies coroutines along with Javascript for web designing.

Its Drawbacks

Kotlin is still not well established. Thus, its developer's community is very small compared to other programming languages.

Koltin tests weak patterns, making it very complicated to read the code.

Kotlin's lofty learning curve and changing teams are due to language strict syntax.

The developer community of Koltin users is very less in the market. Therefore, it is very hard to find an experienced Koltin developer.

The Koltin mobile app development company is still growing. In 2017, Google approved Koltin and made it the second most formal programming language for android app development.

And according to a survey done by Stack Overflow reveals that 61.55% of programmers are using Kotlin for mobile app development and love using it whereas, for Java, the percentage is only 47.15%.

Kotlin Vs Java

Let’s see the difference between these two languages based on their features.

Features 

            Java

        Kotlin

1. Extension Functions

In Java, we have to create a class

It is already there in Kotlin

2. Null Safety

It is not accessible in Java

It is possible in Kotlin

3.  Static Members 

It is present in Java

Kotlin does not contain a static member for a class.

4. Wildcard Types 

Accessible in Java

Not accessible in Kotlin

5. Smart casts

Not present in Java

Present in Kotlin

6. String Templates

Present in Java but does not support expressions like Kotlin

There are two kinds of string templates in Kotlin

7. Operator Overloading

Operators are fixed to a particular Java type.

Kotlin permits users to provide a way to invoke outcomes.

8. Constructors

In Java constructors can be utilized to take parameters

Kotlin includes a primary constructor and a secondary constructor.

9. No Checked Exceptions

It is a bit problematic in Java

Koltin removes exception entirely

10. System Type

There are different kinds of references related to the basic concept of class.

It offers nullability support, universal guards, and type inference.

 So Who Is The Winner In The Battle Of Kotlin vs Java

Well, it is definitely Kotlin. It is because Kotlin compiles with Java and offers a gradual change of codes and a higher-level system to Java.  with elements like declarative, less code, the mixed language database Kotlin is more demonstrative than Java.

In Java vs Kotlin; Koltin is seen as the future language for business application and mobile app development.

Is This The Ending Of Java?

There are very mixed opinions among programmers for this question.

Java is no doubt a reputable language with broad open-source tools and libraries to help programmers.

However, no language is perfect, there are some kinds of faults in every language. With that being said, Java also has some problems that make the work of developers dull. And Kotlin will provide solutions to common programming troubles and will improve the Java ecosystem.

In other words, Kotlin addresses many Java weaknesses.

Summing Up

In 2022, the competition between Java vs Kotlin will get more firm. Both Java and Kotlin have their fair share of benefits and drawbacks.

In Kotlin vs Java,  Koltin is almost similar to Java, and yes so you can go with Kotlin without being anxious about compilation time.

Agree, Kotlin is more android engrossed but, It is still too early to make a decision on Kotlin vs Java. It is because the developer community of Java is very strong and they are not going to replace it any time soon.

I “LIKE” programming

Well just like this blog, when it came to the like system, I wasn’t entirely sure where to start. I had started working on this before we had decided to go with AR built in Unity so I figured I would get the mechanics working and then be able to transfer them into Unity. Initially when we were thinking of building a physical model or projection mapping, I was going to have the like button on a webpage so that anyone could access it, an inherently thats where I started. I had the thought of using a python script to build the whole back end mechanic of the system and that data would be passed from the user via the webpage, and after quickly running this by Liam (who has done something similar before) he agreed that it would be the easiest way and we could have multiple users at once which is what we wanted. I built the most basic version of the “front end” part so that someone could input their name and then like it so the likes would be attributed to them, just like it is on social media.

Liam recommended using the flask module for Python to host the server (and webpage for testing). Once I had installed that I managed to get a connection between the two and even by complete fluke was getting it to receive data from multiple devices and be able to register that it was from different devices. I personally was stoked about this because it was 90% of the like system working but then Liam pointed out, as we don’t know why it worked, if it stopped working we also wouldn’t be able to pick out why. I figured it was in my best interests to learn the best practice for this rather than get the minimum working version as it would be great reference material for the future. In these early stages, Liam helped me a lot by explaining why one way was better than another and generally guiding me through which was super helpful as I was almost coming from no coding background. The main think I am super grateful for is him introducing me to JSON, which I’ll be honest was an absolute pain at first but I now realise it was definitely the best way to go as it was far more reliable and actually made sense. So essentially what was happening is that the HTML page was passing the name that was submitted by the user, to the python script every time the like button was clicked. The script would then add a new value to its own defined variable “like” and count them like that. The bonus of doing it like this is that if someone played once and then after a while came back too have another go, their “score” would compound and keep increasing. On that note though the downside is that if two users input the same name they will have a super score rather than two separate scores. While this would be a downside for an actual game where the score would need to be counted from just one game at a time and not an overall total, for our project it sort of just adds to it. The idea is that the more people “like” the disaster that happens, the more it proves our point that social media is building a screen which separates people from reality and that they can simply click a button to show their support, and the more they do that, the more they are helping? Or at least thats the theory.

In the past when it has come to doing small code projects I have looked up how to do something, found code that suited my need, copied it and then tweaked it to properly fit my programme. However, this doesn’t mean I necessarily understood it which is something I wanted to do differently this time. As this was basically my main role in the team, I wanted to make sure I would be able to explain to other people how it worked rather than have a piece that worked but just because it did. Which I guess relates to this whole degree itself, nothing is really taught to us (especially in studio) and its all self directed so we need to learn the skills ourselves and in this day in age when you don’t need a computer science degree to become a developer but simply be able to copy code from different places to suit your programme, I believe it is quite important to know what you are doing because I the future it will make me far more efficient. And its the learning by doing thing that works really well for me that I like. For example when it came to having to deal with GET requests from both the server and user side, I had done something similar before with the instagram location finder programme that I had had a play with earlier in the semester, and because I had used it before I sort of knew how it worked but then I had the code itself I could look through again and figure out why it worked and what parts I could omit for this different programme. I have to say, I think this semester I have learned more about programming from simply trial and error, Liam and online tutorials than I did in all of last year where I did both programming papers. It was also great to learn this in a group setting where the other team members also are not super coding savvy as trying to explain what I was doing or why I couldn’t do something that we wanted to do due to the nature of the system that I was writing in non technical terms helped clarify what I was doing for myself. I would certainly like to keep doing more programming projects in the future to further develop my skills and learn new things.

Transferring the user side to Unity was a whole different box of frogs though. First of all Unity is all scripted in C# which I have never used before (but luckily is similar to java which I had dabbled in with processing last year) but the whole mechanic of connecting to a server is made a lot more difficult as all requests need to be sent through a Coroutine. Which I’ll be honest, I had never heard of until I stumbled across a million Stack Overflow forums that explained that that is what you have to use. I think I have got my head around them mostly but there are still some things about them that elude me, for example everywhere (including the Unity manual) it says that they end when they hit a “return”, but I have coroutines that have functions or call new functions still enclosed in the coroutine but after the return type and it still calls them (see below).

They also supposedly run for their specified length (of time) regardless where they are called, i.e will run for 6 seconds if told to after being called from the Update( ) function. However, I have found that in some of my code this works, in other parts it just sort of ignores that rule and sometimes it waits for a wee while longer than the instructed time. So its not totally something that I fully understand but I know it enough to be able to use it in the right places and the majority of the function of the Unity scene is run by coroutines so I am clearly doing something right. I like to think of it as a poorly trained animal, I know the commands and the animal knows what they mean but sometimes chooses to do its own thing.

Another major challenge I had was dealing with JSON, for starters sending the exact same data as I was from the webpage but through unity, it was as if it was parson the data into JSON and then parsing the JSON into more JSON even though the commands where almost the same, so on the python side I had to update it so that it decoded the incoming JSON properly so it was then actually processed logically. This brought in a whole world of problems in itself as then the data that was being sent back to the user was all jumbled and messed up which was less than ideal as it felt I had actually gone backwards rather than made progress. But as I have learned from this project, every new error you get means that you are making progress as you have made it past the previous error. After all of that though, I did get it working.

Once I had done all of that, I realised that it was a perfectly functioning Like system that recorded multiple user’s scores and could compound them and it was perfect, but only once. There was no way to restart it without stopping the whole application and going again. So there was the next challenge which proved a lot more difficult that initially suspected mainly due to how referencing different Game Objects is from a script and even harder, referencing the scripts of those Game Objects which is what caused me many hours of strife. To make matters more difficult as well, Unity doesn’t appreciate all the things you could normally do in a C# script so you have to find ways around its very stubborn walls which in my case lead to many, many scripts. Doesn’t sound like such a terrible thing but to make sure each was working correctly I was logging things to the debug console from almost every script so then when I wanted to look for a specific message I was sending to try and get something working, it became a whole lot harder because there were 20+ scripts that were all printing to the console. But once again, I am a champion and figured it out.

As I write this I realise that it doesn’t sound that difficult and didn’t take that long but the code for the like system has been haunting me at night and has been an ongoing saga for weeks . I certainly have learned heaps and am happy with my process that I undertook. However, if I was to do it again knowing what I know now, I would skip out the HTML part and just go straight for the C# scrips because I think that transition was the hardest part of this whole process. In HTML (with javascript) it is easy to do everything all in on document but with C#, you can’t send data and also receive it in the same script, you need to separate them into multiple scripts which is where confusion starts manifesting as you try and think across multiple scripts and have to remember what each one is referencing and how it will then affect the other one. The issue with backend systems as well is you don’t overtly see your mistake as you would with front end because either something happens or it doesn’t and if it doesn’t you then have to comb through your code to find the broken section and find out what is messing you up. Overall I think this is what I found the most frustrating as I have only really done mainly front end development rather than back end, but this project was certainly a great insight into it. Now as for this whole project once we got on a roll, I obviously stopped blogging as I got so engrossed in the work which I do understand is not the best practice but as we were pushed for time (having left it so late to start doing something) I focused solely on getting the work done and from an outsider’s perspective the final product doesn’t really show how much work went into the programming of it, so I have uploaded all my scripts to GitHub so you can have a look at them, and also see how things work if you are interested: https://github.com/JabronusMaximus/ARcde-Scripts
