You can find spring training locations here…

(For the next series of articles, I would assume that programming would be a fundamental part of one’s body, if not, then go practice! Also ,you need to brush up on some Object Oriented concept. Happy Reading)

Today, we would be tackling about Object Oriented Paradigm, in relation with Game Programming. For now, think inside the box.

First picture a room, say for example picture a computer room.

What should be inside this kind of room? More or less we can see a number of  CPU’s, keyboards,mouses,monitors,cables and maybe one or two printers.Is the room airconditioned? Then you can probably feel a little cold inside this room. Hear some music or probably some noise? Is a sound system probably present too?Also, you should not forget about the tables and the seats where the computers are, or the AVR’s where the computers are hooked too! Have you gotten a feel of the room yet?

Planning is almost always done first instead of just rushing in and just coding whatever pops out of the mind. Coding without planning is only done for those things that need to be crammed. Game programming shouldn’t be one of them.

Now proceed to the next step. Ask yourself these questions:
a)Where are you again?
b)How many objects are in the room?
c)Why are these objects here in the first place?
d)What is the purpose of a specific object?
e)How does an object work?
f)What are the functions of these objects? Read more…

Have you ever played a game that you have been so immersed with ? You probably were too addicted that you skipped meals trying to finish a goal or a mission.Have you ever wondered how games as simple as Bejeweled, or as huge as World of Warcraft captivated the hearts and mind of both the young and the old? Well, blame it to game design.These 2 games are very well-designed that once you start playing it, it’s hard to let go.

So how can you say that a game is well-designed. There is at least 3 prerequisites(properties) to well-designed games ,namely:

a) Planned- well-thought-of; plans are usually drafted a number of times before finalization

b) Functional- it works the way it should be ; it should achieve its purpose

c) Tested -ensure everything is going according to plans before implementation Read more…

Transaction: Transaction simply means a unit of work, which is atomic. If only one step fails, then the whole unit of work fails.  When we consider database, Transaction groups a set of statements/commands which gets committed together. If a single statement fails, whole work will be rolled back.   Transactions can be described using ACID criteria. Read more…

       Recently for a  training I started learning struts2.  As I had worked on struts one few years back I started comparing both struts-2 and 1. I found struts2 very easier than struts1.  

Though struts 1 was very popular, comparing it with the newer frameworks, which has come into market in last 2 years, struts 1 has some problems.

•  ActionForms / Action classes etc – one action needed lots of coding and they were a pain
• Also the action class unit testing was difficult.
• Type conversions were not automatic.
• There was no special feature for AJAX in the framework.. etc

Hibernate mapping: the <Class> element: Some useful options

In hibernate mapping file the <class> element maps the domain object with corresponding entity in the database. It will be defined under <hibernate-mapping> tag. <Hibernate-mapping> tag also allows multiple <class> tags inside it. (i.e we can save multiple class mapping information in a single file).

A sample class element looks like below:

<hibernate-mapping>

<class table=”user_tasks” >

<id column=”user_task_id”>

<generator>

</generator>

</id>

.

.

.

</class>

</hibernate-mapping>

Here we don’t discuss all the class element attributes, but some which I found very useful: Read more…
