Steps to Making the Game

Making a complex or unusual game is not easy. But if we want to try for sure there is a way out of her ..I would share what I get from Google. For the steps to make the game it self can be briefly described as follows :

•     Making game idea : Before you start making games , we need to think about what kind of games that we  will create , how to play , what would make people happy to play the game we , and others

•     The process of pre-production : at this stage we need to prepare for various technical issues related to the game that we will create , for example, what technology will be used ( eg, platform or programming language ) , visual art direction or the direction of the game to be made , and finalization game design that we will in the implementation of the game

•     Production process : at this stage we just created art and programming to the game , the game should be developed as much as possible made ​​version that can be played , so it can be tested at the same time we can spread into the community of game developers to ask for input .

•     Release process , at this stage we consider the game finished and we release to the market . But we need to be sure to keep an eye on the comments of people who play our games , if any reports or complaints about bugs or errors should we fix it quickly .

Approximately that the game development process , to flowchart you can seen in the page of BlitzGames .

What the Programing Language to Create Games

The programming language used to make the game very dependent on the platform or technology used . For computer games , there are a few commonly used languages ​​, among which are :

•     C + + , even though they had been there long enough , C + + is still used to make a lot of gaming desktops , ranging from indie games like Crayon Physics Deluxe , even big games like Crysis 2 .

•     C # , can be used in the manufacture of desktop games using XNA , DirectX , or Unity3D . Can also be used to create web games using Silverlight or Unity3D . Examples of web game created using C # and Unity3D is LiloCity from Agate Studio .

•     Java can be used to create desktop games , web games ( with format Java Applet ) , even for mobile games . Examples of desktop games created using the Java example Spiral Knights .

•     Action script 3 , commonly used in making web games Flash Games format , eg : flash games on Facebook such as Shopping Paradise made ​​by Agate Studio or flash games on game portals , such as Earl Grey and Rupert Guy that is also made ​​by Agate Studio .

•     PHP , HTML , Javascript ; The programming languages ​​used to create web games , for example in Facebook like Football Saga .

•     Objective- C , is the specific language used to create computer games that use the Apple Mac OS .

Our advice , learned only one , try to create a game to completion . Experience makes the game was very important , because you will be able to train the basic programming skills and algorithms . Because between programming languages ​​are not too different from the algorithm , so if will need to learn another programming language would be easier if one has mastered a programming language .

What games are most popular in Indonesia?

So far there has been no survey that examines the most popular game genres in Indonesia , but in general there are some genres of games are popular in Indonesia :

•  FPS or First Person Shooter , for example Counter Strike or Point Blank . Counter Strike is one of the most widely played games when the new game center trends emerge around the 2000s .

•  RPG or Role Playing Game : This genre is quite popular among Indonesian games , ranging from the classic RPG games like Final Fantasy , until MMORPG such as Ragnarok Online

• Real Time Strategy : Warcraft or DotA for example , type of game is also popular in Indonesia , with a number of community and competition type game

But there are several factors of a game that we feel preferred by Indonesian people :

• Free-to -play , the majority of gamers in Indonesia prefer F2P models such as subscription models like this than WoW

• An active community , gamers who love the game in Indonesia active community , so they can interact with other players and compete in games

•  Competition , Indonesian gamers excited to compete , and like a game that could facilitate them to compete with their friends , though not necessarily in the form of a formal competition

That data on the game genre that gamers like Indonesia could be more complete , Agate Studio create a survey for Indonesian gamers . Come browse for the progress of the Game Industry Indonesia : D
