How to make games on iOS from scratch. Apps Globus service
The profession of a programmer is one of the most prestigious and in demand, that’s a fact. The software development industry has its niches. Of these, the fastest growing, and at the same time the most highly paid, is software development for mobile devices. As you know, it just so happened that, leaving their competitors far behind, three constant rivals took the lead. The trick is that one of these three is the undisputed leader, while someone always catches up.
In the segment mobile technologies, without a doubt, Apple leads with its iPhone smartphone. At a presentation held in September, the company from Cupertino demonstrated the 7th version mobile device. Along with it, Apple introduced new version mobile operating room iOS systems 10. Now it is the most significant operating system in the world, like its predecessors. It follows that learning iOS development is the best investment of time and money.
Apple ecosystem
Today we will develop a simple mobile application for iOS. Of course, a native Mac is best suited for this. But if you're a Windows supporter or you simply don't have a Mac, you can install the macOS operating system under virtual machine on Windows. On the Internet, it will not be difficult for you to find a version of macOS specially tailored for PC, popularly called Hackintosh. Feel free to install it on a VMware virtual machine, VirtualBox - your choice. Let me warn you right away that the PC keyboard does not have some of the keys that are on the Mac keyboard, and many of their combinations cannot be pressed in Hackintosh. This pretty much spoils the mood. Otherwise, all the operations described below can be successfully performed on Hackintosh.
Required knowledge
To program in general and for iOS in particular, you need to know quite a lot. Mathematics and logic may not be needed at first, but they will be in demand later. Modern technologies relieved the programmer of the need to thoroughly know the computer architecture, but it was necessary to understand basic mechanisms such as number systems, their conversion, the speed of subroutines or the efficiency of algorithms (big O).
At a higher level, an iOS developer needs to have a deep knowledge of the macOS operating system and iOS itself. You also need to master the Apple programming language. Knowledge of Delphi, C++, C# or VB.NET will not help you much. Apple has its own ecosystem with its own languages: Objective-C and Swift. Of course, knowledge of C++ has never harmed anyone; programs and inserts based on it are found everywhere, even at Apple. But the most used by definition is Objective-C, simply because it appeared much earlier (in the mid-eighties of the last century), while Swift only two years ago (in 2014). Apple has high hopes for new language and invests a lot in it. Objective-C is used to support the old software, and the new one is written in Swift. So it's good for you to know both.
In order not to waste time, all these programming languages can be learned under the strict supervision of teachers on the website.
Development Tools
As you know, the main developer tool for macOS and with it iOS is the programming environment Xcode. It includes tools for creating applications for Mac, iPhone, iPad, Apple TV, Apple Watch. All Apple platforms. Xcode contains Interface Builder, a code editor that supports everything modern means working with code. In addition, without leaving Xcode, you can test the application; if it is developed for external device, then you can run it in the emulator.
The system includes emulators of all devices, new versions of which can be downloaded. In addition, Xcode contains graphical tools for analyzing application performance, including tools for diagnosing CPU load, storage usage (HDD, SDD, etc.), load on graphics adapter(from the OpenGL side).
On September 13, a new, hotly anticipated version of the development environment 8.0 was released. Stable versions can be downloaded for free from the App Store. Alphas and betas are distributed by developer subscription. The eighth version includes: a new version of the Swift 3 language, the Swift Playground learning tool for iPad, a new version of Interface Builder, which has become faster and allows you to view the application layout on different platforms, without having to deploy the application itself to the simulator.
Xcode 8 can be used to develop applications for macOS Sierra, iOS 10, watchOS 3 and tvOS 10. All SDKs are available. New versions of operating systems began to appear consistently right after Apple’s presentation, which took place in early September.
Objective-C language
Let us briefly recall the basic information about the language. Objective-C - Object Compiled language oriented programming used to write applications for Apple systems. It is a superset or, in other words, an add-on to C, inheriting from the latter syntax, data types, methods of monitoring the progress of program execution and adding object-based capabilities to it oriented programming- description of classes and methods.
As in C++, in Objective-C the central role is played by objects, which are associated with four paradigms: abstraction, encapsulation, inheritance, polymorphism. C++ is a strongly typed language, while Objective-C is weakly typed or has a dynamic data type system. Like Smalltalk, Objective-C sends messages to objects. This is an exceptional opportunity dynamic languages, because the type of objects is checked at runtime, not at compile time.
The description of the Objective-C language takes up more than one voluminous volume. Therefore, in order to gain objective knowledge, it is convenient to take the “” course. An entire section of the course is dedicated to this language.
iOS application development
As a sample we will develop a very simple application. Let us not deviate from the sacred tradition, let us greet the world. However, taking into account the fact that we graphic application, we will diversify it a little: we will add a button, when clicked, we will display or hide the inscription “Hello, World”.
Launch Xcode, in the window that appears, select Create new project or in the main menu File -> New -> Project. The next window will ask you to select the target platform and application type.
IN in this case we are interested in iOS platform. There are seven types of applications to choose from. Six of them are templates for typical applications of the iOS operating system, containing a different set of components by default. The seventh type is play.
Application Types
- The Single View Application template is intended for simple application with one screen. The preset includes a View Controller component, which allows you to customize the appearance of the application using the Interface Builder form designer.
- Master Detail Application creates an application that displays a collection of objects in a table view. After selecting one of them, they are shown details about this object. The first view is the master, the second is the detailing.
- Page-Based Application creates applications that have multiple screens, like pages in a book. Consequently, e-readers are created from this blank.
- Tabbed application allows you to create applications where each screen can be switched to at any time, that is, each screen has its own button to activate it, on which the title is displayed. An example is iTunes.
- Game is used to create a game template. There are four frameworks to choose from for creating a game: SpriteKit, SceneKit, OpenGL ES, Metal. Let's look at them briefly.
SpriteKit is a system for 2D rendering and animation of textured rectangles - sprites. When displaying frames, a standard loop is used, the frame is displayed after all the contents of the scene have been processed.
SceneKit is a high-level framework for rendering 3D graphics without OpenGL. It supports loading, manipulating 3D objects. It includes: a physics engine, a particle generator and easy way scripting.
OpenGL ES is the industry standard computer graphics. Allows you to visualize 2D and 3D scenes. Allows you to describe the pipeline for a video card: vertices undergo transformation, are assembled into primitives, which are rasterized into a two-dimensional image and displayed on the screen. Programmable shaders can be included in the pipeline.
Metal is a low-level API that will allow you to get the most out of your video adapter. Debugged APIs along with precompiled shaders and multi-threading allow your game to rise to the top. new level productivity and quality. - Sticker Pack Application - the new kind applications introduced in iOS 10 and Xcode 8. It is a set of simple or animated images used in new iMessage. It does not require coding to create it.
- iMessage Application is a new type of application that appeared in iOS 10 and Xcode 8. Allows you to create add-ons for iMessage, for example to purchase and download your sticker pack. You can also use the iMessage API to create your own analogue of this application, including playing audio, video, using stickers, and more.
Creating the first project
As a template for our application, we will select Single View Application. Since we will not be developing a large program, the funds provided by this provision will be enough for us. Click Next. On the next page of the wizard, you need to enter a project name, for example ShowLab. In the Language drop-down list, leave the default language selected - Objective-C. Next, in the Devices drop-down list, leave the Universal selection. Here you determine for which device (iPhone or iPad) the application is being created. The Universal clause means for both. Let's uncheck the Include Unit Tests and Include UI Tests boxes; we don't need any tests. Next. Select a folder to save the project. Now click the Create button.
As a result, a window will open with a list of all parameters applied to the project. In this window, you can change the parameters previously set in the wizard: orientation, target device, etc.
First we need to create the application interface. To do this, select the Main.storyboard file in the list on the left with one click (if this file is not visible, expand the contents of the ShowLab folder). To the right of the list, the entire window will be occupied by Interface Builder. The device layout will be displayed in the center. In the lower right corner of the window there is a component panel. Drag the Label and Button components from there onto the layout. Above the component panel is a list of properties. If you don’t have it, click the Show the Attributes Inspector button, located under the window title on the right side of the interface.
Select the Label component in the layout and configure its Text property: leave the Plain selection in the drop-down list, enter the desired inscription in the line below, in our case “Hello, World”. If the text does not fit within the borders of the label, change them by dragging the handles on the edges of the component. To centralize it horizontally, go to the Size Inspector page by clicking on the Show the Size Inspector button (to the right of Show the Attributes Inspector). On this page, from the Arrange drop-down list, select Center Horizontally in Container.
Now select the Button component, change its Text property to the desired label - Switch. You can center it in the same way as described above.
Creating a connection between graphic elements and code
IN Visual Studio(or Delphi) object in the code is created automatically the moment you place a visual component on the form. This doesn't happen in Xcode, but it doesn't cause problems.
Open the contents of the ViewController.h header file in a separate window by double-clicking on it. This file contains a declaration of an extension of the UIViewController class, marked with the @interface keyword. This feature was added to the second version of Objective-C. Now do this trick: move the mouse cursor to a component - a text label, hold down Ctrl key And left button mice. Move the cursor to the window with the code (file ViewController.h), a blue line will follow the cursor. Release the mouse and key inside the ViewController interface description.
The Outlet creation window will appear.
This is a property of an object that refers to another object (in this case, a visual component). You need to enter the name of the Outlet object, by which you will access the visual component, let it be lab. Next, the object type is selected, it is selected correctly: UILabel.
Even lower in the Storage list, select the type of object reference: weak or strong. If you choose strong, then the object pointed to by the property will exist as long as the property points to it, in which case it will not be automatically deleted when it is no longer used. On the other hand, when a weak reference is in effect, the object can self-destruct. So, select the weak link type and click the Connect button. As a result, the following line will be added to the code:
@property (weak, nonatomic) IBOutlet UILabel *lab;
Let's make sure that Outlet is a property.
Now let's create an Outlet for the button. The algorithm remains the same. Only for the Name property you need to enter a different name, for example but. The line will be added to the code:
@property (weak, nonatomic) IBOutlet UIButton *but;
As a result, we have two pointers to visual components: lab and but - respectively, an inscription and a button. Now, using pointers, we can manipulate components in code.
Then you need to create a button click event handler. To do this, open the implementation file ViewController.m in a separate window. In exactly the same way as you dragged the line into the header file to create the outlet, from the button, drag the line into the implementation file and drop it to the closing command bracket - @end. A window for creating an event will appear, similar to the window for creating an outlet. You see the difference: a link to an object is created in the header file, a method is created in the implementation file.
Fill in the Name field, its value represents the name of the property - method. Let it be onClick. Leave the Type field value as default - id. In Objective-C this type is the ancestor of everyone else. In the Event drop-down list, the Touch Up Inside event is selected by default, which occurs when the pointer (mouse, finger...) is released over the button, that is, the final stage of pressing the button. That's what we need. In the Arguments list, leave the default value: Sender is the object that sent this signal, in our case it will always be a button. Click the Connect button. As a result, the following code will be added:
- (IBAction)onClick:(id)sender ( )
A minus at the beginning means a closed method (private). Keyword IBAction is marked with events (methods) visual components from Interface Builder.
Between the command brackets we will write the code that is executed when the button is pressed:
Lab.hidden = !_lab.hidden;
In this line of code we invert the value of the hidden property. It is of type BOOL, which has two values: YES - true and NO - false (somewhat unusual for Windows programmers, where true and false).
Pay attention to the underscore character before the name of the object - the label (_lab). Without it, compilation will fail. The underscore is added automatically for objects contained within other objects; that is, in this case, the lab object is contained in the ViewController object. Previously, this was a convention used to distinguish between objects declared as members of a class and local objects. And now this is a strict rule implemented in the language compiler.
Now you can compile the application and run it on the simulator. We chose the simulator for iPhone 7, included in Xcode 8. The compile and run button is a black rectangle and is located in the bar at the top of the interface.
After compiling the application, launching the simulator and loading our application, its interface will be displayed on the simulator screen: the inscription “Hello, World” and the Switch button. If you press the last one, the inscription will disappear; if you press it again, it will appear again.
We have made a very simple application to understand the essence of iOS development. You can learn more detailed information about creating iOS applications in Objective-C from the course by our friends from GeekBrains “”. The course devotes two months to learning this language. During the first month - introductory topics, and in the second - real coding of professional applications.
Swift language
In 2014, Apple introduced a new programming language - Swift. It quickly became the most talked about and fastest growing language in the world. It's reliable, safe, intuitive clear language for developing applications for operating systems macOS systems, iOS, tvOS and watchOS for the entire fleet of Apple devices. Swift is an efficient programming language. It's easier to learn than its predecessor, Objective-C, and Swift borrows some of its best ideas. At the same time, the developers have made the languages compatible, that is, one program can contain code in both Swift and Objective-C. There are billions of lines of code and hundreds of thousands of legacy programs written in Objective-C in the world, so its support will definitely not be abandoned.
When developing Swift, the goal was to create the most convenient system programming language - fast, safe and expressive.
The algorithm in Swift is 2.6 times faster than the same algorithm in Objective-C, and 8.4 times faster than in Python. Using Swift makes the program development process more flexible and convenient.
Due to its exponential development, the Swift language was released to the open source community on December 3, 2015. At the same time, Apple strictly monitors its development, organizing a committee for its development. Now Swift is available not only in Apple systems, but also on Linux. All additional tools for working with the language, including a debugger, standard library, package manager, are also free and open.
This language is the future. You can find out more detailed information about it from the mentioned course from GeekBrains “”, in which a whole month is devoted to studying of this language programming.
App Store
Simply put, the App Store is a content store for the entire range of Apple devices. Here you can buy games and applications from both large companies and independent developers. Every developer, no matter what country he lives in, can sell or distribute his programs for free on this digital distribution platform. To start doing this, you need to register as a developer and buy a license to sell your applications. This is a fee for the service provided and the development of the App Store.
Results
We have developed a simple application for the iOS mobile operating system using the Xcode programming system along with the Objective-C language. Tested ready application on an iPhone 7 simulator. We learned how to build a user interface using Interface Builder, how to link graphic elements with application code, how to create event handlers. We got acquainted with the basics of Objective-C. In addition, we drew attention to the promising Swift language, used to develop powerful and secure applications for the “apple” ecosystem.
However, the material studied is only the beginning. In order to intensively upgrade yourself in the direction of mobile coding and the development of actually selling applications, we recommend taking the “” course on our friends’ website.
This is a worthy course: if you take it, you definitely won’t waste your time. It starts with two detailed courses on Java language, followed by learning basic programming for a mobile operating system Android system. Further course on databases in general and SQL language in particular. Then an in-depth course on developing professional Android applications. After this, the vector of study will move towards Apple systems: two detailed courses on the Objective-C language and useful course by Swift.
The course lectures are taught by professional teachers with extensive experience in software development. If something is unclear, you can ask a question without delay. In general, learning on GeekBrains is a live process, you can communicate, ask questions, and help with answers. To test the acquired knowledge, teachers issue homework, which is then checked. After completing the training, you will have a guaranteed internship in an IT company. And then everything depends on you, if you show yourself as a competent specialist, you will be invited to work.
Special project with the company
So, the thought also occurred to you: “ How can I learn to write programs for iPhone?«, « How can I make my own mobile app? «, « How to make millions without doing anything?". I will try to answer these questions step by step (except for the last one).
What you need to know from the very beginning
To create programs for iOS You are officially required to have a computer Apple (iMac or Macbook). But to be completely honest, you need an operating system OS X, so many people are cunning at first and manage to use Hackintosh (Hackintosh), that is, they run OS X on regular computers- This is an economical option, illegal and quite troublesome in terms of setup. I recommend that, since you have firmly decided to become an iOS developer, buy a simple Macbook or Mac Mini, or even a used one (any one released since 2010).
Next - what to write on. Applications for iOS written in programming languages Swift or Objective-C, and all the magic happens in the program Xcode(free). Swift is a very new language that Apple introduced just recently (mid-2014) and is now actively conveying the idea that you only need to program in it, it is the future, it is more modern and faster. And they are right, learn Swift. Objective-C on the contrary, a language with a long past, so it is much more difficult for beginners to understand, which does not negate its power and the wealth of existing developments and books on it (which cannot be said about Swift at the moment). And yet, I repeat, teach Swift.
If you want to make cross-platform applications (simultaneously for iOS and Android) - learn C# and use the development environment Xamarin(paid). If you want to make cross-platform games, download the development environment Unity3D(shareware), learn the one already mentioned above C#.
Also, in order to launch your applications on iPhone/iPad (even at the development stage) and then upload them to the AppStore, you need to buy a status Apple Developer for $100 per year. After the purchase, this once again motivates you to at least recoup the money :)
When I asked myself this question, I thought that I just needed to take a good thick “bible” on Objective-C (let me remind you, Swift did not yet exist) and comprehend the secret knowledge of the programming language chapter by chapter. Everyone recommended Stephen Kochan's book " Objective-C Programming«. Wrong! Don't repeat my mistake. Yes, the basics of the language were understood, the book is good, but this is a reference book and is far from real application development from scratch. To learn to program you need to “get your hands dirty”, trying to write the first, albeit very simple, but working applications. You need lessons with examples. From simple to complex. It’s also important to set a real goal, the first application that you want to write and release in the AppStore. Each lesson or book should give you knowledge that you can apply to your project. Don’t make the mistake of the “eternal student” who only does what he studies, studies, studies, but postpones the moment of starting real work. For example, I set myself the goal of making a radio application and releasing it on the AppStore in a month - and I succeeded.
If you know English, consider yourself very lucky, now I will tell you where to get all the knowledge. Unfortunately, there is very little information in Russian and it is often late (and translated from English).
The iOS ApprenticeThe best English-language training site - RayWenderlich.com. It’s mega-cool for three reasons: 1) you can read a ton of lessons for free, from the basics to trying to repeat existing ones successful applications(including in Swift), while everything is written sincerely and with humor; 2) there are video lessons there (albeit paid); 3) The most important reason - they have books for beginners that will teach you from scratch using the example of creating applications, very clearly, with pictures (well, as we like). The books are paid (only the first part is given for free), but they are worth it. I bought them all and they have long since paid for themselves as they build a good foundation brick by brick. It can't be compared to just reading different lessons mixed on the same site. Start by purchasing The iOS-apprentice (the first part of which can be downloaded for free). It will teach you how to create your first applications in Swift. They also have books on game development on SpriteKit(Apple's framework for game development).
The second most useful resource is AppCoda. It is simpler than RayWenderlich, but the essence is the same - we read Swift lessons, learn from examples. They also have their own books (paid), in addition to free lessons.
What if you don’t know English - oops, there are simply no such Russian Internet resources. Books in Russian? Of course, you will find some books on Ozon, but they are all outdated and will not teach you Swift language(at the moment everything is only in Objective-C).
The best thing I can offer you is the “iOS development” hub on Habré, new articles are constantly appearing there, but it’s very chaotic.
Where to find the answer, something doesn’t work
While programming, you will constantly have questions: you don't know how to do something, or you do something, but the program responds with an error. You can find answers (or ask a question) on two sites:
StackOverflow- the largest storehouse of ready-made answers in English. I find 80% of the answers there.
Google- it’s trite, just by typing a question into the search, you can find the answer. If it doesn’t work out right away, play around with the wording of the question.
Toaster- similar to StackOverflow, but in Russian. It is still difficult to find answers here, since the database of questions is not very large yet. But you can ask - there are enough professionals on the resource who will answer you.
Or you can ask me. Free for now :)
Many people have probably thought about creating their own iOS application. However, if you are new to this business, the first step in mastering it will be to solve the question “where to start.”
The main goal of this article is to set guidelines for a novice iOS creator, with the help of which it will be easier to understand where to start their development in this area. You will learn about the necessary developer tools, get acquainted with the main programming language for iOS applications Objective-C, learn what Cocoa is, get a number of useful links etc.
iOS Developer Toolkit
Getting started, first install all the necessary tools: Xcode - created by Apple a program for creating applications for OS X, iOS and the iOS SDK.
Xcode is an amazing thing that provides everything you need to develop applications for iPhone and iPad. Xcode's user interface is a single working window ( workplace window), where all the magic happens: from writing code, checking it and debugging bugs to developing the software interface. The iOS SDK mentioned above, designed to extend the Xcode toolkit, requires no additional download and is installed automatically with Xcode.
Thus, as you already understand, all work begins with installing the latest version of Xcode, which can be found in the Mac App Store.
The second step will be to register a newly minted iOS programmer in the iOS Developer Program. Registration is necessary if you are serious about the development and promotion of your brainchild in the AppStore. Otherwise, you can stop worrying and limit yourself to the Simulator included in the iOS SDK.
You can learn about the next steps in mastering Xcode here:
Objective-C language
Objective-C is an object-oriented programming language used to create iOS applications. Objective-C is a superset of the C language, which means you can write code in both C and Objective-C.
Here is a small selection of various resources (books and websites) that can help in mastering Objective-C: For those who know English:
Frameworks
Any iOS application is created using Objective-C and Cocoa frameworks. Frameworks developed by Apple contain a library of functions that your application calls upon. At the same time, several applications can have access to the framework library at the same time.
Apple creates frameworks that already contain everything necessary functions, which saves time and is a kind of guarantor of the quality of the work done.
For those wishing to learn more about the topic here:
Templates
Necessary help when creating standard applications for iOS are project templates. However, this does not mean that templates solve all problems: after familiarizing yourself with the basic iOS Design Patterns, the developer will one way or another have to “hew” his creation in accordance with existing needs.
Attractive shell
The visual component of an iOS application is not given less than value than functional. Therefore, it is important to remember the importance of the interface when developing software. The main expectations of users from the application in visual terms can be described in a few words - attractiveness, interactivity and, most importantly, intuitiveness of the interface.
More about interface design:
And a couple more points
Now let's digress a little from the technical component and turn to ideas. When creating any application, it is important to understand what the purpose is and what functions it will perform. Decide whether the application will only work on iPhone, or maybe iPad, or whether it will be universal. Spend a little more time and decide on the type of data model, interface style, and study frameworks. All this will help you understand the software architecture more clearly.
This concludes our excursion into the world of iOS application development and it is assumed that you now have the answer to the question “where to start.” The rest is all in your hands.
If you haven’t found an answer to your question or something didn’t work out for you, and there is no suitable solution in the comments below, ask a question through ours. It's fast, simple, convenient and doesn't require registration. You will find answers to your and other questions in the section.
Mobile applications are what every smartphone owner uses today. At any time you can look up the way to the desired place, translate an unknown foreign word, read a new book, listen to your favorite music. That's what smartphones are all about: limitless possibilities right here and now. Now you can not only use popular apps, but also create your own. How to do this - we'll figure it out together in the article.
Writing a program on your own today is a prestigious and profitable business. A potential developer has a chance to make good money, provided that his application is in demand.
Therefore, it will be a shame if you waste your time creating a program that will not be used. To prevent this from happening, a novice developer needs to study this fascinating process in detail. The demand for an application depends not only on consumer needs, but also on the skill of its author.
There is another side to the coin: the average person simply wants to come up with a program that is more convenient than others already proposed today. A program that he will use himself. For example, an improved calculator, organizer or dictionary.
If you want to make money from your program, do not forget that it must be original. Banal photo editors or new mail client will not help you get rich. Think over the idea in advance and determine how your creation will compare favorably with other similar ones.
How to create an application for iOS and publish it on the App Store
If you already have an idea for an application, you should stock up on working tools. These will be: a computer and the Xcode development environment.
How to create an application in Xcode
Xcode can be found in the AppStore. Download it and install it on your device.
Download the Xcode development environment from the AppStore
To create your application in Xcode, follow these steps:

Loading iOS simulator will take some time
Test the application by launching it. If you did everything correctly, it will launch and display the content correctly.
Check that the application starts and works correctly
Video: how to create an application for iOS
How to test the created application
To check the functionality of your application, follow the instructions:
Enter your Apple ID
Connect your device to your computer to test the application
In the device management settings, allow the installation of the program
Open the application using the desktop icon that appears to check its operation
If the application opens and works correctly, you have done everything correctly and you can start using your program.
Testing of iOS applications will be available after registering in the App Store as a developer and paying the initial fee. A program for diagnosing new programs is called TestFlight.
How to publish the created application
The App Store Review Guidelines contain a list of rules that a new app must meet. To publish a program to App store Store, you need to log in to https://developer.apple.com/register/ using your AppleID or create a new one account. For individuals The pleasure of presenting your app to Apple developers costs $99.
Possible problems when creating applications
The development environment used to create applications is convenient and simple enough for a beginner. The main problem you may face is your lack of technical skills. Therefore, if you are serious about developing apps on the App Store, be prepared to practice a lot. Studying literature from various sources in this area will also help you.
When you decide to try your hand at creating iOS apps, don’t be afraid to make mistakes. Start with an original idea and develop it using the capabilities of the development environment. Practice, develop your skills, follow news and trends in the field of IT technologies. And, perhaps, your application will not only become popular and recognizable, but will also bring a decent profit.
Who hasn't dreamed of creating their own game for iPhone and iPad? The gaming industry is now developing at a rapid pace, and the desire to try oneself in this direction is quite natural. Many are afraid to become a professional because they believe that this is not an easy task, requiring extreme concentration and rich experience. However, you can start your journey towards your dream without programming skills.
One of the tools for developing two- and three-dimensional applications and games is the Unity game engine. With its help, applications are created for Windows and OS X, as well as for iOS, Android and . In addition, the engine is used on PlayStation 4, Xbox 360, Wii and others. Unity is very popular among developers such as Blizzard, EA, Ubisoft, since working with the engine is quite simple, the interface is convenient and there is free version. The editor is easy to customize and has several various windows, which makes it possible to debug the game directly in it.
The project itself in Unity is divided into levels, which are also called scenes - these are separate files with game worlds, containing their own sets of scripts, objects and settings. Scripts interact with objects that contain sets of specific components. And thanks to the support Level systems of Detail highly detailed models are replaced with less detailed ones if the player is at a long distance.
The Unity editor is truly multifunctional: an object inheritance system, scripts in the form individual components, support for rigid body and fabric physics. Getting to know the engine on two levels, including the interface, creating scripts, developing terrain and creating a multiplayer game - this and much more is offered by the GeekBrains service.
This profession has a difficulty rating of 2/5, while being most in demand at modern market, and you can master the development in just six months. To start this course, you do not need programming skills: the main thing is interest and desire.
