Get Started in Game CreationWritten by Daniel Punch
I’ve always loved video games, ever since I first played them on a friend’s computer in afternoon after elementary school. There’s something almost magical about fact that we can move images around and interact with virtual worlds, a living fantasy presented for us to interact with however we please. I’ve also always wanted to make games myself but, until recently, didn’t have technical knowledge to do so. Now, I’m a second year software engineering student, so if I weren’t able to code a game without too many dramas there’d be something drastically wrong. But what about common person: person for whom term ‘memory leak’ conjures up images of their grandfather, ‘pipeline’ is where water flows, and ‘blitting’ is unheard of? Well, everyone can get in on game creation process, and you don’t even need to learn ‘real’ programming to do so.So where do games start? With an idea. Games, like all fiction, require an idea to be successful. Sure, in same way you can just sit down and write a story without foresight, you can jump on in and slap a game together. However, unless you get ridiculously lucky, best works are usually ones that have been well thought out beforehand. There are two methods of planning a project. You can start from a known technological standpoint and build your project on top of that or you can just go for design, add as many features and ideas as you like, and then remove ones that you can’t use when you’ve decided on technology you’re going to implement game with. In general, second type is probably best one to go with when designing games. When you’re first starting out however, first option will save you many headaches. So, for a first game you’re going to want a pretty simple idea. Don’t get me wrong, crazy-go-nuts game ideas are fantastic, and there should be more of them out there, but you’re not going to be able to create a real world simulator with fifty billion virtual people all interacting real time with your actions having a butterfly effect on future of virtual universe when it’s just your first game. Really. Many people try it; none that I know of have succeeded. Imitation is best way to start out. Simple games such as ‘Space Invaders’, ‘Tetris’, ‘Pacman’ or even ‘Pong’ are great places to start. All are largely simple to create but have some inherent challenges. ‘Pacman’ for example, requires path finding for ghosts. I recommend that you start even simpler than that for your very first attempt. ‘Space Invaders’ is a nice point to jump in. You can make a simple, complete game without much effort and it’s almost infinitely extensible. If you’re stuck for an idea, pick a genre that you enjoy. Do you love adventure games such as ‘Monkey Island’, ‘Grim Fandango’, ‘Space Quest’, ‘King’s Quest’ etc.? Design one of those. Are you into fighting games like ‘Street Fighter’, ‘Tekken’, ‘Soul Calibur’, ‘Mortal Kombat’ and so on? Come up with an idea for that. Do you like first person shooters such as ‘Quake’, ‘Half Life’ or ‘Doom’? I don’t recommend it as a first project, but you can always give it a go. Feel free to be as generic as you like, this is a learning experience after all. Now that you have your idea it’s time to flesh it out. Don’t worry about technology or fact that you may not know how to actually implement a game just yet, just grab yourself some paper and a pencil and go crazy with ideas. Describe main characters, game play, goals, interactions, story, and key mappings, anything you can think of. Make sure you have enough detail so that someone can read through notes and play through game in their head with relative accuracy. Changing game design during coding process is almost always a bad idea. Once it’s set, it should remain set until tweaking phase (I’ll go into this more later) or you’re likely to enter ‘development hell’, where project goes on and on; more and more work is done with less and less outcome. At end of this period of your game creation, you should have following: -A written outline of game’s characters and possibly a sketch or two (be they space ships, yellow circles, cars or prince of dark kingdom of Falgour, you need to know who or what player will be and who they will compete against) -A written outline of story (if there is one, this isn’t too vital for ‘Space Invaders’ or ‘Tetris’, but for ‘Uber Quest: An Adventure of Awesomeness’ it’s a really good idea) -A description of game play, written or storyboarded. Storyboards are visual representations of ideas. Draw your characters in actions, with arrows showing flow of action and short written descriptions detailing events occurring in your image (because some of us aren’t fantastic artists and our images can be a little… open to interpretation…)

High-speed Internet access via Cable Modem and DSL has made multi-media web browsing possible. I can remember when downloading simplest of games could take an hour or more via a dial-up connection, and putting photos on a web page was taboo because even small thumbnail images took too long to load. These days it’s not uncommon for folks to have hundreds of music files, movie clips, & games on their hard-drive. It’s easy to fill up a 30-gigabyte drive because a song file can take only a few seconds to retrieve from a remote server. There was a time when a mere 64kb was a lot of space! My new toaster probably has more than that! But, I digress… These advancements in computing speed and power do come at a cost, but no one has ever taken time to explain these caveats to us “regular” people. There are, at a minimum, a few things you should know regarding DSL or Cable Internet access. We’ll talk about two of biggies in this article, namely: Security and Housekeeping. The fact that your DSL or Cable connection is “always on” has really opened up a can of worms if you are not informed & prepared to take some basic protective measures. It used to be, that when we dialed into Net via a regular, analog modem our service provider (Earthlink, AOL, Prodigy, etc.) would assign an IP address to our PC each time. This address would change every time you hung up and called back in. That’s what they call a ‘Dynamic’ IP address: it changed when you reconnected. Think of your PI address as your PC’s phone number on Net. Once you connect, that's how your machine is identified and how your data or traffic gets routed to you. We entered era of high-speed access & with it came common use of ‘Static’ IP addresses. The address no longer changes because your machine is always connected to Net. There’s no reason to reassign a new IP address because you don’t hang up. You generally keep one you have for an extended period of time. Why should this matter to you? Well, just like after having same phone number for a while almost guarantees you’ll be getting interrupted during mealtime (marketing time), a Static IP address can leave your machine open to thorough probing from outside and ill-intentions of others on Net. The more time a hacker can spend trying to access your machine, better his chances of success. In other words, it’s harder to hit a moving target (a dynamic IP address), but you ain’t goin’ anywhere if you have a Cable Modem or DSL! And remember, while there are laws here in US, which aim to protect you & I from these rogue villains, Net is literally a no-mans-land. Our laws do not apply & are ignored & even scoffed at in some of places where hacking attempts originate. Don’t panic, though, there are things you can do to minimize chances that prying eyes will find their way into your machine. First and foremost, be sure you have some sort of Firewall installed. A firewall is designed to minimize chances of an outside attacker being successful. Notice I said minimize? No security on Net is foolproof. Period. Someone once remarked that only way to safeguard a PC is to turn it off, disconnect it, cut all of wires, and bury it in ground & then MAYBE, it would be safe from hacking attempts! A correctly configured firewall can help you beat odds. If hacker is having a tough time getting in to your PC thanks to a Firewall, they’d be better off trying another, less stubborn machine. There are a couple of different types of Firewalls for you to consider; first & most common being a Software Firewall. If you have Cable or DSL service, your provider probably gave you at very least an introductory or trial version of a Software Firewall like McAffee or Norton Internet Security. Spend some time getting to know these programs and their settings. It can save you a lot of heartache.
