I what to make my career in game developing so what i have to do?

Hey Ashutosh ,
Greetings!

Because coding is by definition the creation of a mathematical equation that directs the computer to perform in certain ways, game programmers need high level math skills in order to be successful. Northeastern University recommends that incoming freshman seeking a degree in video game programming have had high school coursework in trigonometry, physics, and calculus. It is also important for game programmers to understand linear algebra and basic algorithms. If you are lacking in some of these courses, be prepared to take them early in your college years.

Gaming programmers may have a general background in computer science or they may have completed a formal education program to become a video game designer. The U.S. Bureau of Labor Statistics notes computer programmers most often have bachelor's degrees. These degrees are often in computer science or computer engineering. A bachelor's program in video game programming will typically include classes in C++, calculus, object-oriented design, game algorithms, computer graphics, and network fundamentals. Degrees in computer game programming can be earned on campus or online.

The most effective way to get noticed by gaming studios is to create games and put them in a portfolio. According to senior technical staff from Blitz Games Studios, a successful portfolio should include several small games that can be played to completion. The portfolio should offer the viewer links to all the installation software needed for each game to work. As a backup, there should be screenshots of crucial game scenes so the games can be evaluated even if the support software products required are not readily available at the time of the portfolio review. The portfolio should have source code for all the games. The notes should give credit to any collaborators who might have helped with elements of the game's design, programming or presentation.

Entry level programmers often have difficulty breaking into the video game industry because most major studios require experience. Some new programmers find their first professional positions at smaller studios, making short, simple games for mobile devices and social media sites. One way to gain an advantage in the competitive job market is by networking on the blogs, forums, and websites most often visited by game developers. Sometimes the professional contacts gained through these sites will ask for portfolios or advertise available positions not found on traditional job boards.
