INTRODUCTION

Nowadays the number of online web games increases day by day. With easier and faster internet access globally such online web games are gathering greater attention from the community at large. With social networking sites like Facebook, supporting games as applications has seamlessly grown, 62% of all gamers have been reported playing games online, breaking away from the traditional standalone PC or console systems. There were 217 million online gamers worldwide in 2007, and their number has been escalated ever since.

Flash games have taken a slight hit in recent years since the advent of mobile gaming. iOS devices such as the iPad and iPhone, among the most popular devices, do not support Flash games. While Android doesn't support it, the entire gaming experience is sub-optimal. Adobe has also renounced its support for Flash on mobile devices, choosing to focus on PC or Mac web plugins. It is perhaps their strategy to transit over for Flash-to-Apps development, or HTML5 altogether.

But still, Flash games remain one of the more approachable gaming platforms online. In recent years again, we have seen Flash being able to handle 3D gaming, and advanced physics modules such as Box2D. However, Flash is still much more suitable for casual 2D gaming.

Flash games come with a low game size footprint, hence making it very accessible even for people with low bandwidth.

Do not learn how to create a World of Warcraft in Flash, because that would definitely go beyond the scope of any online tutorials. Instead, focus on casual games where the overall casual games industry is estimated at $2.25 billion a year. According to the CGA 2007 market report, it is growing by about 20% annually [1].

1 TECHNOLOGIES OF DIPLOMA AREA

The chapter begins with the general characteristics of the enterprise. We give a small work history of the enterprise. The company's mission. Purpose, objectives and types (forms) of activity. Our Business. The international cooperation. Analysis of models of business organization - online / offline. The presence of offices in the Internet. Analysis of the main sources of income and expenses of the enterprise over time. Main partners and customers. The organizational structure of the enterprise. Principles of production, organizational and economic structures of the enterprise. Information support of the enterprise management functions. Consideration of hierarchical relationships.

The main issues at the market study are the following:

- Condition industry

- Target Market Characteristics

- A study of consumers

- Competitive situation

At the very least the online browser game industry for all types of games is smaller than it was two years ago in 2013 and appears to be at best stagnant and still vulnerable to further decline. The most popular games websites are shown in figure 1.1 and figure 1.2.

Figure 1.1 - The most popular games websites

Figure 1.2 - The most popular games websites

To survive in such a market both developers and publishers have economized and moved significant amounts of their resources to mobile game development, often using online games for cross-promotional purposes [2].

1.1 Technical and economic description of subject area

Economics is a social science that studies how individuals, governments, firms and nations make choices on allocating scarce resources to satisfy their unlimited wants [3].

Technical descriptions are used before products and processes are developed (as part of proposals and planning documents), during development (in progress reports, for instance), and afterwards (as part of marketing and promotional literature and technical support documents) [4].

The quality of the product is determined by:

- The viewpoint of the user of expert software product;

- The point of resource use and evaluation;

- The software product should be designed so that it performs its functions without the expense of resources (RAM, CPU time, and others - on the stage of the operation, development time and financial resources - at the stage of use of the software product) [5].

The content of the feasibility of development of the program is as follows:

- Determination of the cost and complexity of software;

- Calculation of the cost of staff salaries;

- Calculation of capital and operating costs for the development. Economic efficiency - is to get the maximum possible benefits from the available resources.

An important part of the efficiency of the economic system is the efficiency of capital investments. It is expressed as the ratio of the obtained effect to the capital investments that caused this effect.

A rather large role in the economic process (whether economical software or not) depends on the programmers creating this software. Then play the role of the creation, debugging, and operation of the program.

For the economic analysis of the effectiveness of the investment project is traditionally used indicators such as the payback period (Payback Period, PP).

Payback period (Payback Period, PP) - the time during which investment returns are equal to the initial investment (the period necessary to ensure that the funds invested in the project is fully returned.)

Together with the net present value (NPV) and internal rate of return (IRR) is used as a tool for evaluating investments.

Payback period - it is an excellent indicator that provides you a simple way to know how long it takes the customer to recover the initial cost. This is particularly important for businesses located in countries with fragile financial system, or business associated with advanced technology, where rapid product obsolescence is the norm, which makes a quick refund of investment costs in an important problem. Just these figures tell us about how to effectively apply the software product taken by us and the savings from its use.

1.3 Rationale for using computer and telecommunication means for problem solution

For the work, necessary to install the software package. To save the software for the design stage can be set in the workplace programmer. Thus, we need a PC laptop with an exact Intel Core i5, and with the input device and a manipulator "mouse" type - 2000 tg.

Plan of creating flash game:

- Develop the idea

- Create the storyboard

- Write the design document

- Create the preloader, the menu, and the other window screens first.

- Writing the ActionScript classes.

- Creating introduction gameplay.

- Creating history buttons.

- Creating design.

- Create xml database.

- Create animation.

- Access levels (see figure 1.3).

Figure 1.3 - Access levels

The game industry has grown steadily for decades, and it has a very brighter future. But with so many gaming technologies, you may be wondering if Flash technologies are the right choice.

Games are a serious business.

Online gaming became popular in the 1990s. As computers have become more powerful and Internet access speeds have increased, the industry has grown significantly (see figure 1.4).

Figure 1.4 - Online gaming

Annual online game revenue in billions of U.S. dollars from 2006–2011. DFC Intelligence.

The online gaming market research:

- 2011 online gaming revenue is projected to be $10–12 billion worldwide

- 70% of revenue will be PC-based (as opposed to video game consoles)

- 30% of revenue will be casual games (as opposed to so-called hard-core games)

Approximately $3–5 billion of 2011 revenue will target online computer games, such as projects created with Flash technologies. Americans spent more than $3 billion in video game subscription fees last year. A report by market research firm Pike & Fischer estimates that Americans will spend $5 billion annually by 2015 [6].

1.4 Problem statement

A problem statement is a brief description of the issues that need to be addressed by a problem solving team and should be presented to them (or created by them) before they try to solve the problem. The primary purpose of a problem statement is to focus the attention of the problem solving team. However, if the focus of the problem is too narrow or the scope of the solution is too limited, the creativity and innovativeness of the solution can be stifled [7].

1.4.1 Aim and purpose of creation or modernization of IS modules or services

The purpose of my diploma project is to develop the game, "Kazakh kaganate" using object oriented programming, which will promote our country abroad and be helpful to those who will study the history of Kazakhstan and Kazakh language. To develop flash game which consists strategy or tactic logic.

1.4.2 General characteristics of the problem solution process by means of information technologies

In order to solve the problem, it is necessary to install such programs as: Adobe Flash, Adobe Photoshop and Corel Draw.

Adobe Flash uses a movie-making metaphor. The basic terms used to describe animation or Flash applications are movie, stage, and motion terms. A Flash animation is called a Movie. A movie contains all the scenes, objects, effects and actions that make up the final animation. In a real movie, you have a stage where the action takes place and a camera that takes the film. A movie is a collection of Scenes. Just as in a TV show or real movie, each scene may have a different background or camera angle. The plot of the movie flows from one scene to another. A simple animation would have a single scene. A scene is a collection of Objects that animate over a number of Frames. When a scene is complete, all the objects are removed from the display and the movie automatically moves to the next scene. Typical objects are text and image objects, such as a picture of a car or a person. Following the movie-making metaphor, the work area for your Flash animations is called the Stage. Objects, such as drawings, buttons or animations are placed on the stage in Layers. This allows objects to be in front of other objects. It is also useful for breaking up effects into simple parts. The very first layer (and the furthest back) is the Background. This layer is usually visible through a whole scene. The Timeline is the part of the interface where you can see the flow of a movie, as you would in examining the film of a movie. The Timeline consists of frames, events, actions, and effects.

The Timeline is an animated strip of film. It is into individual frames that show events and actions. Just as you could lay one strip of film on another, you can have layers in the timeline, such that both are seen in the movie. A Frame is a single time-slice of the Flash movie. It is a similar concept to a frame of a motion picture. Frames are seen in the timeline. An Event is when something happens at a given time in the movie or as a result of a user action. A frame event occurs when the movie reaches the specified frame. Mouse events occur when the mouse interacts with an object in a scene. The event will then trigger an Action, which can be used to control the flow of a movie or issue instructions to the browser. Typical actions include stop the movie at the current frame, go to the specified frame (and scene) in the movie, and tell the browser to load a Web address into the specified target HTML frame. Effects are animations that change the appearance of an object over time. A Simple Effect is where all components of an object move in unison. An example is when all images slide into view at one time. Another simple effect is a Transformation of size, rotation and/or color. Complex Effects are several objects in a movie (typically letters of a text object). Complex effects are usually done in layers. Some Flash rapid application development tools, such as Swish, have complex text effects preprogrammed into one layer. The basic metaphors used for Flash animations are classified as movies, stages and motion [8].

Adobe Flash, commonly referred to simply as Flash, is a multimedia system for computers that is generally used for standalone development and as a method of creating user interfaces and menus on some older cell phones. Flash was also the technology used to power many major video websites (YouTube among them) in their early guises. However, the use of Flash has declined and in 2015 it is rarely used aside from for some mobile games, with even most video providers now turning against the software because of its security vulnerabilities. Flash can be used to create entire “Flash sites” or to add interactive elements to standard HTML sites. Some Flash-only sites are accompanied by non-Flash sites in an effort to cater to a wider audience. Flash technology can also be used in interactive banner & button advertisements. The use of large-format rich media ads has attracted much attention, plus a little controversy, and may signal a trend towards large, rich ads by publishers looking to add premium placements [9].

1.4.3 Formalization of the problem solution algorithms

The precursor to ActionScript was introduced in Flash Player 4. It enabled a wide variety of interactivity in Flash, but it was not a very sophisticated or familiar language. Its syntax and semantics were very different from ECMAScript, although in later versions it was possible to apply ECMAScript-like syntax to it.

ActionScript 1.0 was introduced in Flash Player 5. It had ECMAScript-based syntax and semantics. With the release of Flash Player 6 and Flash Player 7, the language received some semantic tweaks but remained essentially the same.

ActionScript 2.0 was introduced in Flash MX 2004 and Flex 1.0. This new version of the language also worked in both Flash Player 6 and Flash Player 7 because ActionScript 2.0 is actually a layer on top of the ActionScript 1.0 runtime. As a result, ActionScript 2.0 isn't as high-performance as it could be, because under the hood it's still using the same object model as ActionScript 1.0.

During the planning stages for Flash Player 9, it became clear that we could not continue building upon the current ActionScript engine that was powering both ActionScript 1.0 and ActionScript 2.0. Adobe began working to completely rewrite the ActionScript Virtual Machine (AVM). The result was a highly optimized virtual machine known as AVM2, along with a new version of the ActionScript language to target it. Although AVM2 will be the primary virtual machine for ActionScript code execution going forward, Flash Player will continue to support the older AVM1 to ensure backwards compatibility with existing and legacy Flash content.

Reasons to use ActionScript 3.0

The following are the primary benefits of learning to use ActionScript.

a. Your skills will be to high demand

In my opinion, is the main reason why anyone who currently works or would like to work as a Flash developer should switch to the new language. All major Flash work is now exclusively being built in ActionScript 3.0. You just don't see many jobs looking for ActionScript 2.0 skills. So if you plan work with Flash, learning ActionScript 3.0 is essential.

b. Everything you build will be faster

Developers who have been working with Flash for a while have often been frustrated that our new, super-cool idea just couldn't run smoothly because of the limitations of Flash Player. ActionScript 3.0 offers up to a 10-fold increase in performance over previous versions of the language. In some cases, the performance has increased even more. This means you can control more objects on the Stage at the same time. If you want your project to look and perform at its best, moving to ActionScript 3.0 is the ultimate way to achieve this goal.

c. There's an abundance of new APIs

As Flash developers, we love nothing more than getting new toys to integrate into our projects. ActionScript 3.0 includes hundreds of new APIs for working with things like XML, regular expressions, and binary sockets. Even better, the whole language has been reorganized into packages and namespaces that make it much easier to find specific language features. When you use ActionScript 3.0, your Flash toolbox is better organized.

d. The display list rocks

One of the biggest changes in ActionScript 3.0 is the way Flash handles visual objects in a movie. In previous versions of the language, it was practically a black art to manipulate the display order (depth) of the items in a Flash movie. A large number of hacks and workarounds existed that didn't make any sense to use the language. For instance, it was common practice to place visual assets at an extremely high depth in order to keep them on top of everything else in a movie. This led to a lot of problems in larger projects and required a lot of manual depth management work. The new display list in ActionScript 3.0 is a straightforward mechanism that handles how visual assets are rendered in your movie. Once you start using it, you'll wonder how you ever developed a project without it.

e. The object-oriented structure is better

Developers particularly desire the improved object-oriented structure of ActionScript 3.0. It includes things like runtime typing, sealed classes, packages, namespaces, and an overhauled event model. Programming in ActionScript 3.0 is on the same level as writing in other high-level languages like Java and C#. The new features in ActionScript 3.0 also make your code more modular, readable and extendable. Some of these features may not be used much, if at all, by interactive designers—but it is good to know that if you want to get into more advanced programming someday, the language structure is there to support you [10].

1.5 Analysis of existing solutions and rationale for the proposed module/service technology

Alternative technologies of adobe flash (see figure 1.5, figure 1.6, figure 1.7):

Figure 1.5 – HTML5

Figure 1.6 – openfl

Figure 1.7 – Jangaroo

Jangaroo can be a solution for Flash developers who wish to keep using this language and enjoying the advantages of OOP, while also utilizing the benefits of JS. The weak points of this technology are the necessity of testing bugs in JS through a different language. Also, a potential problem is the missing documentation and unstable support.

Openfl can become a useful assistant to Flash developers looking at alternative technologies and trying this and that. Also, is can help with porting a Flash product into Haxe. But you have to be prepared for difficulties with cross-browser bug-fixing and lack of documentation, as the technology is new.

HTML5 is a cross-platform kit of well-established and globally known technologies with a lot of individual and corporate contributors. Also, many programmers are interested in working with it, as such projects are good for portfolio. On the other hand, HTML5 application development requires really high professionalism, and its capabilities are limited when you need to create a more complex interface or a 3D game. Also, you will have to keep an eye on every step of testing and bug-fixing, especially if you are targeting a lot of mobile devices [11].
