1. Tell us do Playfish And Zynga Use Flash Game Engines?
Briefly, yes. Zynga's Café World and PlayFish's Restaurant City uses Away3D.
I think developers might use more of 3d engines because 3d is not everyone's cup of tea - they can just focus on implementing game logic and mechanics instead of meddling with math. However they would shy away from game engines like Flixel, for reasons that Nick Wiggill has mentioned. (eg. risk of middleware)
2. Tell me what Are The Problems You Might Face While Developing Game With Java?
☛ a) Garbage Collector : Non-deterministic memory management could be a problem
☛ b) Lack of third party libraries: Most of the available libraries do not support Java. Java has huge class library built in but they are not game related
☛ c) Not supported by game Console: Java is not supported by popular game consoles.
☛ d) Smaller Community: Most game programmers use C++ , so if you are developing games on Java, you can expect least help from others as very few programmers can give you the solution for your query.
3. Tell us why Is It Important To Have More Than One Person Creating A Game?
Every game design needs play testing by many different players. Usually each player tries a different strategy, and so the designer can see which strategies pay off best. A good game design permits many different strategies, balanced so they offer equal chances of success.
4. Tell us what Are The Android Tools Used For Developing Games?
Various tools required for developing games are
☛ a) Eclispse: Integrated Development Environment (IDE)
☛ b) ADT- Android's Eclipse Plugin
☛ c) Android SDK-includes ADB
☛ d) Hudson- Automatic build tool
5. Explain me how creative are you?
I would say that I am very creative in areas that I am good at producing materials for, and would be more than happy to learn about areas I am not so good at and be more creative in them.
6. Tell us how Can You Reduce Game Lag?
To reduce game lag you can either lower the performance setting for the game or by upgrading certain parts on your computer.
7. Tell us what's the best game of all time and why?
In my opinion, the best game of all time is Minecraft, because of the endless possibilities. You can build, fight, survive, socialize. Minecraft, from building a little hut to building a giant castle.
8. Explain me what Is Vertex Buffer Object?
Vertex Buffer Object is a method for uploading vertex data to the video device for non-immediate mode rendering. Vertex Buffer Object is an OpenGL feature.
9. Tell me some Of The Html5 Framework Game Engines?
Some of the HTML 5 framework game engines are
☛ a) Construct 2
☛ b) Turbulence
☛ c) CAAT
☛ d) Phaser etc.
10. Tell us what Popular/famous Games Are Written In C?
Doom, Quake, pretty much all id games up until id Tech 4.
11. Tell me an example of the most challenging algorithm you've created?
It would be an open world video game and it has to be mmorpgs. I live actions fantacy and others.
12. Tell us what Is The Basic Structure For Developing A Game?
The basic structure for developing game is
☛ a) The game interface
☛ b) The implementation of the interface
☛ c) The game source code
13. Tell us different Methods Used For Storage In Android?
The storage methods used in android are
☛ a) Shared Preferences: Store private primitive data in key value pairs Internal Storage: Storage of private data on device memory
☛ b) External Storage: Storage of public data on shared external storage
☛ c) Network Connection: With your own network server you store data on the web
☛ d) SQLite Databases: In private database it stores structured data
14. Do you know what Is Cloud Gaming?
In Cloud gaming, the game is hosted on a game server in a data center, and the user is only running a client locally which forwards game controller actions upstream to the game server.
15. Explain is There A Centralized Database Of Game Names And Ids?
Alien Shooter II - Vengeance
Alien Shooter: Vengeance
Is there some place that I can go to get an ID or the 'canonical' name for these games? I suspect that they are the same game, but it's very hard to say for certain.
16. What is the concept of object cloning and how is this used in java?
There are times when one needs to use the exact copy of an object for a specific purpose, without changing the actual object in any way. The option, in this case, is to create another similar object, which will require a greater amount of memory to be expensed, and this is where the construct of object cloning provided by java comes to prove beneficial.
The clone() methods of the object class implement the concept of object cloning but require the implementation of the java.lang.A cloneable interface of the object class whose clone you are trying to create. Devoid of this, a CloneNotSupportedException is generated by the clone() method of the class.
17. Explain me the Advantages And Disadvantages Of Using Packed Buffers?
The advantage of using packed buffers is that it is more efficient for the GPU to render, since all of the information needed to render is located within the same block of memory. The drawback of packed buffer is that it would be difficult and slower to update if you are using dynamic data.
18. Explain me how Good Bitbucket/github Is For Game Development?
Bitbucket is a code hosting service and not a file sharing service. It is compatible for small size game development, but if you are handling extremely large files or frequently changing binary files Github would not be useful. Bitbucket can't display differences on binaries
19. Please explain any Good Web Frameworks For Asynchronous Multiplayer Games?
Service Stack for services and serves up XML, JSON etc. Amazing in general for setting up the services. Also cross platform.
As far as 'DB communication', if you are able to use Windows Server for hosting, Entity Framework works well, however is code gen but very easy to use and code against. There might be alternatives like DbLinq (Linq To SQL for Mono), but haven't tried it so not sure on how easy it is to use.
Obviously, this is only really an option if you don't mind coding all this in C# and doesn't take care of all the database design you'll have to do, but that kinda goes with game logic.
20. Please explain how To Program To Make Video Games?
There are software applications that will allow you to make fully functional video games without any programming. But, keep in mind if you want to be really good you need to learn how to program.
21. What is the use of ‘this' keyword in java?
The ‘this' keyword is widely observed in all java codes and scripts, and it, in fact, is a reference variable which is used by programmers to refer to the current object in use. The method of the current class can be suitable invoked using the ‘this' keyword. The java compiler implicitly adds the keyword to the method, if you do not specify the same.
FPS means frames per second, which tells about how much information is used to store and display motion video. Each frame is a still image, and the illusion of motion is created by displaying these frames in quick succession.
23. Tell us in Android, How You Can Use Load Texture Method To Load The Image?
The load texture method will take in an image pointer and then load the image into a stream. The stream will then be loaded as a texture into OpenGL.
24. Tell me what Do You Mean By “lag”?
In online gaming, the delay between the action of players and the response time of the server is known as ‘Lag'.
25. Tell me how To Be An Artist To Design Video Games?
There is plenty of prepackaged images and art that you can use either for free or by purchasing that you can use in your video games. But if you want to get really good then you have to put in the time to develop your artistic skills.
26. What are pointers are and elaborate if they can be used in java?
Pointers are a special class of variables which are available in a lot of programming constructs such as C++. These are used to reference a particular position in the memory and this is coming off as a very powerful way of explicit memory allocation, management, and traversing amounts memory units.
Pointers are however not supported or available within Java, as they can get quite complex with the segregation of the stack and the heap memory in java.
27. Professional Java Game Developer Job Interview Questions:
☛ How do you know if a linked list has a cycle in it? As in, one of the nodes in the linked list points to a previous node in the list.
☛ Describe the characteristics of an ACID database system.
☛ Is Java a statically or dynamically typed language?
☛ What do we mean by polymorphism, inheritance and encapsulation?
☛ Do arguments in Java get passed by reference or by value?
☛ What is the difference between an abstract class and an interface and when would you use one over the other?
☛ Why use an object Factory and how would you implement the Singleton pattern?
☛ What is the difference between “==” and equals(…) method? What is the difference between shallow comparison and deep comparison of objects?
☛ How is Java EE related to Java SE?
☛ How are Runtime exceptions different from Checked exceptions?
☛ What is the difference between HashMap, ConcurrentHashMap and a Map returned by Collections.synchronizedMap?
☛ Servlets 3.0 introduced async support. Describe a use case for it.
☛ Why do you think lambda expressions are considered such a big thing in Java 8?
28. Explain me what Is The Average Job Length In The Game Industry?
Since the industry is project based job length tends to be directly associated with product cycles.
The is often the result of the post ship layoff. Companies tend to dump staff once a project ships since they don't need a full production team for pre-production on the next project. Now the nicer companies tend to use temporary contract hires for short term production staffing needs. This lets the employee know that they likely don't have a paycheck when the project ends. However the big publishers regularly cut even full time staff once the xmas games are sent to manufacturing.
The other piece is that when finishing up a title employees are more likely to look around at other options. If you've just shipped your third football title and are burned out on the genre you tend to wait until the game is done and then find another job somewhere else.
While there are some devices that have spent an entire career at a single company, what is far more common is finishing 1-2 games at a developer and then moving off to another one.
I am a 2D Game Programmer.Some programming languages which I am good at are C,Java ,C#. I also know Actionscript 2.0,3.0 and some javascript. I'm interested in learning 3D Game programming. So far from the research I have accumulated by googling and reading different game development forums and articles. I've noticed that most programmers tend to prefer C++.Also in an online game programming teaching course I noticed they prefer to teach C++ and Visual C++ as the starting course. The reason I am asking this question since I would like to know the "strength" difference of C++, C# and Java for 3d game programming.
29. Tell us when An “onsurfacechange” Can Occur?
When the screen size changes the “onsurfacechange” occurs, and this can happen when the device orientation changes.
30. Tell me how Can I Measure The "creative/entertainment Value" Of Video-game Requirements?
The only real way we have to test such things is with, well, testing. Professional game developers will tell you all the time that the single most effective way to know if certain gameplay is working and fun is to give it to players and observe.
Indeed, one of the reasons that achievements are everywhere these days in games is because they give invaluable information to the developer. If you want to know where players stopped playing your game, make an achievement for completing each level. If you want to know how many players aren't playing a certain race in Civilization, look at how many people got the achievement for playing that race. And so on.
31. Explain me is Java Viable For Serious Game Development?
Yes it is, check this list for a proof. Those are some games made with Java using The Lightweight Java Game Library (LWJGL). It is a low-level framework, which provides OpenGL for high quality graphics and OpenAL for sounds. It also provides input API. With these you can quite easily get started to serious game development in Java.
I am currently writing my second 3D game as a hobby project in Java, and I just love it. In the past I used to write my games with C++, but after switching to Java there is no going back. Supporting multiple operating systems with Java can be very easy, for example my previous Java game, which I developed in Windows for a year, worked in Linux right away and in OS X with only one bug without any need to compile anything on those platforms.
On the other hand, with Java you have couple of problems.
☛ Garbage collector. As others have stated, non-deterministic memory management is a problem, and you need to code that in mind.
☛ Lack of 3rd party libraries. Most of the available libraries do not support Java. On the other hand you always have the option to call these native libraries from Java also, but it's more work to do so. There are also Java ports or ready-made wrappers available for popular libraries, for example I'm using JBullet - Java port of Bullet Physics Library. On the other hand Java has a huge class library built-in, which reduces the need for third party libraries that are not game related. The lack of libraries has not been a problem for me, but I can imagine that it can be for others.
☛ Java is not supported by popular game consoles and there is no easy switch to those from Java as far as I know. On the other hand Android, which is a popular mobile platform, uses some form of Java. This is an option also, but don't except the same Java code to work both on a PC and Android device.
☛ Smaller community. Most game programmers use C++ and in my experience often dislike Java. Don't expect to get as much help from others. Don't expect to get a job in game development without C++ skills.
I like to think that I am a sort of quality assurance assistant. Know that I am helping to make the game better for everyone would keep me motivated.
33. What is the meaning and the use of the static keyword in java?
Static is a commonly used keyword, which is associated with variables, methods and nested classes in java. The real use of the keyword is for memory management of these constructs, as detailed next.
1)Static variables in java
When a variable is created as static in Java, it gets memory allocated to it only once, and that too when the class in which it is declared gets loaded. This is the reason why these variables are used to declare properties of other variables which are shared amongst them and do not change.
2)Static methods in java
Methods in java can also be declared as static, and as such, these are then connected to the entire class, without being limited to any single object of the class. Invocation of such a method declared as static does not require the instance of the class and these methods can work on the static data of the class and can even make updates to the value of static constants and variables.
This is also the reason why the main function in java is by default static and hence no object is required to invoke it and this leads to a better memory management.
34. Tell us what Are The Gaming Engines You Can Use For Developing Games?
The different gaming engines you can use for developing games are:
☛ 1) AndEngine
☛ 2) Rokon
☛ 3) Libgdx
☛ 4) Android-2D-Engine
☛ 5) jMonkey Engine
☛ 6) Cocos2D-Android
35. Explain me what Is A Game Loop?
For any game development game loop acts as a central component. To make necessary updates and to check the changes in the game, loop is useful. Graphics, movement, controls etc. all rely on the game loop.
