What do you suppose is the building block of all 2D and even some 3D games? If you guessed sprites, you’re completely right! The sprite is a magical tool that game developers have been using to simplify the game development process. In the case of XNA, the sprite makes up the building block of all graphical content.

What Sprites Accomplish in XNA Game Studio Express

Game sprites are more common that you might think. Every character, weapon, bullet, tree, and virtually everything else is usually assigned as a sprite. Very few 2D games can do without sprites (although it’s possible but also impractical). 3D games also use these 2D sprites for heads up displays, particle effects, and other trivial graphical matters.

Since these sprites are so important to games in general, XNA Game Express has a lot of built-in support for them. Developers, programmers, and designers can all add a sprite via the Content Pipeline. This is just a fancy phrase to describe the simple upload-and-use method that Microsoft XNA developers graciously created for us.

But just as it is easy enough to upload the sprite and reference within our code, it is just as easy to manipulate the sprite in question. There are built-in functions that allow game programmers to modify attributes such as opacity, tint, size, scale, rotation points, and even use what is called sprite sheet animation.

Most of the built-in effects are major time saving functions- which has led to some very interesting games produced via XNA as a result. If you want a character to turn invisible at the drop of a hat, just set the opacity value accordingly. If you want to show off a smooth 30-frame animation for a roundhouse kick, then sprite sheet animation is just as easy to accomplish.

Using Sprites in 3D XNA Game Studio Express Games

Sprites are also used in 3D games, albeit less on average than 2D games. As we mentioned before, they are generally for particle systems, heads up displays, menus, and other trivial functions.

Particle systems in particular are very important. When the smoke of a barrel rises after a shot, you can bet that 2D sprites are being used in most cases. When an earth-shattering explosion knocks dust and rocks into the air, 2D sprites are again most likely at work. Although advanced 3D games don’t even need to make use of 2D sprites as particle effects, most homebrew games do.

But what many (even advanced!) games can’t avoid is getting information to the player- which, coincidentally, requires 2D sprites. Menu effects, information to show things such as health or ammunition levels, pause menus, profile screens, and much more will still make use of sprites.

Final Thoughts on XNA Game Studio Express and Sprites

XNA Game Studio Express is a true blessing, what with its vast support for sprites. The on the go functionality of XNA Studio Express allows better games to be made in less time- and as we can see, much of the time is cut at the sprite level.

Game developers will tell you that a game without sprites is improbable. As a result of this fact, and the fact that XNA makes it so easy, we are seeing many developers shifting to XNA game development- and rightly so.

Every time you use your computer, install and uninstall programs, move around files etc you are building up a list of registry issues and problems which can be easily fixed.

However, if you ignore these and continue to use your computer on a regular basis, the errors will mount up and it will become more difficult to fix the inevitable problems and errors.

In order to fix your windows registry and restore it, please follow the instructions below:

1. Isolate The Registry As The Problem

In order to isolate the problem, let’s eliminate the problem of spyware and viruses.

I therefore recommend that you run your antivirus and anti-spyware software programs first, make sure they are full system scans and not a ‘quick scan’ which clearly does not scan all files and folders.

If nothing shows up, then you can be pretty certain that your PC problems lie in the registry.

2. Backup Your Windows Registry

Please note: If you use a recommended registry repair program, they will backup your registry for you automatically, saving you the hassle.

In order to manually backup your registry, go to Google and type in “backup your registry” – you will find plenty of information on this.

3. Fix Your Registry Problems

Warning: Only edit, modify and ‘fix’ your windows registry manually if you are an IT professional. This is because the smallest change to your registry can cause severe problems – to the point of your PC not operating. Be careful!

If it’s a simple problem, you’ll hopefully be able to perform a system restore from a date prior to the error(s).

If not, either hire a computer repair company to come to you and fix your PC, or…

Save yourself a lot of money and hassle and use a highly recommended registry cleaner to automatically backup your registry for you, and then isolate each and every problem within it.

Obviously the choice is completely up to you as it depends on how much time and money you have to spare.

New registry cleaner products are coming out on the market all of the time. Make sure that you read reviews on the products as much as you can if you are wanting to purchase some software.

The more reviews that you read, the more you can guage the quality of the product.

Also, even though there are free registry cleaner solutions out there, just be aware that because they are free, no money is being invested in these programs to keep them up-to-date and their databases expanding.

Those products which you pay a small fee for are continually improving and expanding are therefore more likely to find a wider range of errors and problems than a free one.

Clearly though free is great! Just be aware of the issue that lies behind it though.

One of the grandest inventions of all time after the personal home computer has got to be the laptop computer. So many people today own them and many find it very difficult to function throughout their day without them. Business people treasure them, but so does everyone else that owns one.

There is so many of us everywhere that use this item on a daily basis. School students and mamas that work from home appreciate the easy maneuverability of the laptop. A stressed to the max mom can move them from home to other places when she is on the go and students are able to have them at school as well as the house. You can find need for them if you are riding in a vehicle, anywhere you might go off to. Wireless internet connections have grown and the amount of spots that they might be used is continually increasing. Individuals can even take it on vacation.

Due to all the portable options that you can get that comes from a laptop, also comes all of the threat for losing it, someone stealing it, or it being damaged. Just like cell phones, theft, loss, or damage due your own actions sometimes will not be replaced under your warranty. Water mishaps are a serious thing that can happen to a laptop more often than some of the other incidents. Liquids being splashed into the laptops keyboard and soaking the circuit board can destroy it easily.

If this should occur and the laptop gets exposed to water or some other wet substance, do not do not freak out just yet. When only water has wet your laptop, there might be more hope than you thought. Even your files might be saved if you are very lucky. First flip it upside down to let out all the liquid you can. Get the battery out and dry it good with a cloth.

What you want to do next is remove any screws that keep the case together. With an absorbent, lint free cloth, gently dab at the moisture. Then just leave it be for a full 24 hours. Be positive it is thoroughly dry before you put it back together and test it. If it still will not come on or is not working properly, do not mess with it further.

Be advised, this procedure is just if your laptop was saturated by water. If it was cola or another sticky or acidic thing, you can still unplug it and take out the battery pack. Even though it is possible to clean the circuitry with alcohol, you may possibly do more damage to a laptop that could be repaired by a skilled computer specialist.

There is arguably nothing more mentally draining and mind bogglingly boring that completing your staff payroll. Especially if you have to do it manually. Further still it is one of those odious tasks that has to be completed with real attention to detail. This is not a job you want to make a mistake on – it could lead to some extremely disgruntled workers or worse still some small mistakes could leave you out of pocket.

So there is no doubt that there is a need for making this whole process easier. Of course modern technology has jumped in to fill the void and computers have made the process much easier. For those of you that want and for those of you that need to make the whole process easier it is possible to use payroll software. This type of software will probably make your life easier. So what can payroll software do for you and how can you make the most of it?

Payroll software can be a great tool for speeding up the process of calculating pay accurately. It can help you make payments on time and it can make it less necessary for you to completely understand the complex laws that govern pay and instead provide you with a semi-automated system that means you will complete your pay roll within the legislative guidelines. This can mean that an added bonus of this type of software is that can, as a result of ease of use, reduce the costs of administration.

It is vital that everyone in your organisation is paid accurately and on time. If this does not happen it can cause disastrous motivation problems that could have far reaching ramifications on the success of your business. It is an extremely important aspect of your business and therefore it is vital that the staff that are responsible for completing the payroll are well trained. This can be quite time consuming and it could cost a lot f money and time to keep your staff members trained to perform this important task.

Payroll software can make the process easier by making calculations quick and easy. A piece of software will typically be able to complete calculations that might take hours, if done manually, instantly. It will also automate end of year reports and all of the pay slips and reports will be saved in the system so that if you need a copy in the future you will be able to print one off quickly and easily without having to scour through a filing cabinet to find it.

The software can also calculate deductions in pay such as tax and national insurance so that you don’t have to. Better still it is able to keep a list of the running totals so that you can keep up to date with the amounts of tax that gave been paid. This can make life a whole lot easier. It is also possible that the system can be incorporated with the timesheet of your employee so that it can be calculated to coincide with the exact number of hours that your employee works. It can also keep useful information like the start and end dates of an employees contract so that the staff costs can be analysed quickly and easily.

VoIP which stands for Voice over Internet Protocol is changing the way people think about making long distance phone calls.

VoIP uses technology that can translate analog audio signal, the signal traditionally used for telephone calls, into digital data that can be transmitted over the Internet and translated back to analog at the other end, if necessary. This technology can also be used without traditional phones, bypassing the phone company (and the outrageous fees) altogether. This technology has the potential to completely revolutionize the telephone industry offering a whole range of new choices for the consumer.

It is highly possible that this technology will eventually completely replace the traditional phone system.

There are several ways to take advantage of this new technology including both pay and free services available through the Internet. Some require purchasing new equipment to make and receive phone calls with a traditional telephone and others make and receive calls through your computer using the speakers and a microphone.

There are advantages and disadvantages to both methods with the computer method being available for free, but requiring your computer to be on and connected to the Internet in order to make or receive calls and the traditional phone method usually requiring the purchase of additional equipment and a monthly usage fee. Even with the fee, however, in most cases VoIP would prove to be a considerable savings over the standard telephone company’s bill.

Actually, there is a good chance you are already using VoIP technology without even knowing it. Many of the big-name long distance telephone service providers are already streamlining their networks using VoIP. This technology takes advantage of sending information electronically in the form of packets instead of the traditional method of circuit switching.

By using packets the information is sent only when it is created as opposed the circuit method which leaves a circuit open for the entire duration of the phone call so that there is a constant flow of information in both directions even when only one person is talking or when nobody is talking at all. Since the packet-switching method only sends actual data as it is created there is much less information “traffic” making the whole system much more efficient.

VoIP phone plans usually include all the premium services such as call waiting, caller ID, call forwarding and three-way calling in their one low (or free) fee rather than charging extra for each of these like the regular phone companies do. This provides yet another advantage for the VoIP customer.

There are even more premium features that go beyond what a standard phone company is capable of, such as filtering calls and routing specific phone numbers to either another number or a predetermined recorded message. Imagine sending all telemarketers to a “this phone is no longer in service message.”

The only potential drawback for some customers is not having access to a high-speed Internet connection. This can pose a problem for close to 50% of Americans who are still forced to use traditional dial-up connections. For the other 50%, however, VoIP is a viable alternative to the high phone bills and lackluster service they have been getting for years. The technology is still in its infancy and its popularity is likely to skyrocket in the coming years.

One of the greatest inventions of all time after the personal home computer has got to be the laptop computer. So many people today own them and many find it very difficult to function during the day without them. So many other people use them than just in the business sector.

People with all kinds of lifestyles use a laptop to enhance their lives. School students and mamas that work at home keep them at hand. An active mom can move them from spot to spot when she needs to and students like to have access to them at school as well as many other places. You are subject to need them anywhere you might venture to. Wireless internet services are so great and the number of spots that they might be used is continually getting bigger. Even going into the wilderness is not always out of the question.

Because of all the flexible options that you enjoy with a laptop, there is a fear of misplacement, someone stealing it, or damage getting done to it. Being similar to cell phones, loss, theft, and damage through your own fault are not likely to be replaced under your warranty. Water accidents are a major thing that gets done to a laptop quite frequently. The chances of all kinds of liquids getting splashed in the laptops keypad and getting inside to the circuit board, seems to be less avoidable than with the tower of a desk top system.

If this should occur and a laptop gets contacted by water or some other wet substance, do not panic. It is entirely expected that you might because you will not only be scared of losing the laptop, but all the files it kept for you that is impossible to put a price on and can be impossible to recover. The first thing that you do is unplug immediately. Flip it upside down to get out as much liquid as possible. Remove the battery and dry it completely with a cloth.

The next thing you do is carefully disengage the screws are holding it together. With an absorbent, lint free cloth, very gently dab away the liquid. Then simply leave it alone for an entire 24 hours and possibly longer. Make very sure it is thoroughly dry before you attempt reassembling it and turning it on.

Just remember, this procedure is just if a laptop was exposed to water. If it was soda or any other sticky or acidic liquid, you should still disengage and remove the battery. Even though you may clean the circuitry with alcohol, you might possibly do more damage to a laptop that might be fixed more easily by a skilled computer specialist.

It is practically inevitable that one day, at some time or place your computer will break down, this is when IT support services can come in useful. I have lived in London for many years and this truism has been part of my ethos for many years; having efficient IT support services on call is both a valuable and essential resource. Even experts are susceptible to faults that they cannot fix at some time or the other; hence IT support is a service that all computer users must employ at one time in their lives.

One problem when living in London is finding a support worker from the company that sold you the computer in the first place. They are out there but tracking one down and employing their services can be somewhat difficult. There is little doubt that one day your computer will have to go back to the manufacturers, there are certain problems that even the most experienced IT support services cannot remedy.

As the manufacturer has the best idea of the operations of the computer, it is them who will be able to fix it most easily; rather than sitting at your computer staring into nothingness for hours, it may be worth the trek across London to see the manufacturers IT support services.

When purchasing your computer, a major consideration should be the standard of IT support you may receive after your purchase. Without efficient support services, you may find yourself with a piece equipment that you cannot use and has no value in real terms. With so many suppliers in the London area the choices are limitless and your decision should include not only the initial price but the level of IT support you will be subjected to. Especially if your computer is for your business, downtime can mean lost profits, so the value of efficient IT support can be immense.

The chain of support is something that occurs regularly in the IT support industry, even when you call out the services to fix your computer, it is often the case that they will simply call the manufacturer support and charge you for the call and time spent dealing with the manufacturer. Often it is worth calling the manufacturer direct, there are some manufacturers in the London area who provide services that will have your computer up and running in no time.

A good IT support worker is worth their weight in gold; there are many in the industry, especially in London who will dumbfound customers with technical jargon that they have no hope of understanding. Making sure everything is explained clearly and concisely should be a major concern. If you manage to gain an understanding of what the IT worker is doing, chances are you may be able to fix the problem yourself if an when it happens again.

Your IT support worker should also be knowledgeable about the product you possess, if they are lacking in sufficient knowledge, it is doubtful that they will perform any worthwhile work and charge you for nothing. Your IT support services should ideally be in the same district of London as where your computer is, as time is money, the amount of time spent with a broken computer can be extremely expensive for your business. Unfortunately it is rare for manufacturers to have IT support services located throughout a city, the majority of the time they are a phone call or a considerable drive away.

IT support services are vital to those of us who rely on our computers daily. When your computer is your life having someone who can fix it close at hand is an essential element of successful computer use. Whether these support services come from the manufacturer or an independent source is irrelevant as long as their knowledge is adequate. Hopefully you will never have to use them but with so many things that can go wrong with a computer, it is doubtless that the IT support services at your disposal are a true lifeline.

Technical expert Thomas Pretty has used computers for many and considers the value of IT support services London in high regard. To find out more please visit http://www.scottadam.co.uk/
