Tutorial 4: Make a Game in 60 Minutes This tutorial helps you learn about the process of game construction, while guiding you through writing a relatively complete game. The code in this tutorial illustrates the technique described in the text. A complete code sample for this tutorial is available for you to download, including full source code and any additional supporting files required by the sample. Understanding the basics of game coding is the single most-difficult step for a beginning game programmer. Think of the idea of your ship on the screen. If, for instance, you wanted to add a second ship that would also draw on the screen, and had the ability to move and turn, you would have to create a copy of each of the variables you were using for the first ship. For a game that will ultimately have more than a dozen objects all drawing and moving around, this is unworkable. Start by right-clicking on your project in Solution Explorer, and select Add, then Class. Start with drawing the ship's model. Figure 1. Figure 2.
Pete's QBASIC / QuickBasic Site The Shapes of CSS Learn Development at Frontend Masters CSS is capable of making all sorts of shapes. Squares and rectangles are easy, as they are the natural shapes of the web. Add a width and height and you have the exact size rectangle you need. Add border-radius and you can round that shape, and enough of it you can turn those rectangles into circles and ovals. We also get the ::before and ::after pseudo elements in CSS, which give us the potential of two more shapes we can add to the original element. Square Rectangle Circle Oval Triangle Up Triangle Down Triangle Left Triangle Right Triangle Top Left Triangle Top Right Triangle Bottom Left Triangle Bottom Right Curved Tail Arrow via Ando Razafimandimby Trapezoid Parallelogram Star (6-points) Star (5-points) via Kit MacAllister Pentagon Hexagon Octagon Heart via Nicolas Gallagher Infinity via Nicolas Gallagher Diamond Square via Joseph Silber Diamond Shield via Joseph Silber Diamond Narrow via Joseph Silber Cut Diamond via Alexander Futekov Egg Pac-Man Talk Bubble TV Screen Lock
Beginning Game Development: Part VIII - DirectSound | Coding4Fun Articles Welcome to the eighth article on beginning game development. We have spent a lot of time working with the graphics capabilities of DirectX. We also covered how the DirectX API allows us to control input devices. Now we are going to look at another facet of DirectX, the ability to control sound devices. This capability is found in the DirectSound and AudioVideoPlayback namespaces. Sound in Games Sound creates an ambiance in a game that provides for a more immersive game experience. Sound effects also provide the same audible cues we expect in real life, such as the direction and speed of a person approaching us based on the volume, direction, and frequency of the footsteps. In BattleTank2005 I want to integrate sound in the following way. Secondly, I want to be able to play background music during game play and I want to control what music plays when in the game. DirectSound The DirectSound namespace only supports playing 2 channel waveform audio data at fixed sampling rates (PCM). Device
Gestures and Tools for Kinect - Eternal Coding You have certainly not missed (as a regular reader of this blog ) that the Kinect for Windows SDK is out! For now, however, no gestures recognition services are available. So throughout this paper we will create our own library that will automatically detect simple movements such as swipe but also movements more complex such as drawing a circle with your hand. The detection of such gestures enable Powerpoint control the Jedi way ! (similar to the Kinect Keyboard Simulator demo). If you are not familiar with the Kinect for Windows SDK, you should read a previous post that addressed the topic: There is an infinite number of solutions for detecting a gesture. Algorithmic search Template based search Note that these two techniques have many variants and refinements. You can find the code used in this article just here: GestureDetector class Skeleton stability
Blogs I was looking over the .net award nominees this week and stumbled across the flipboard.com website. I loved the scrolling navigation so much I just had to open up visual studio and try and recreate it myself. DemoView Demo The main thing flipboard do differently is to have the logo and logo background elements move at different animation speeds from each other and the main content. This effect is is similar to Parallex scrolling and gives the website more interest, depth and flair. I’ve documented the main steps to recreate my demo below: Step 1 First we need to make reference to the jQuery Library as we are going to use it alot. Step 2 Next we will want to add our HTML to the page this HTML will hold all of the layers and links that we will need to get the example running. The background triangle moves at a slightly different speed to the logo and so needs it’s own <div>. I have added the nav layer and placed 4 links into it so that the user can navigate between the different contentItems.
How to write a 32bit screen saver © 1997-1999 Lucian Wischik. This article describes the fundamental nuts and bolts of writing a saver. I have also written a second article with a more useful higher-level overview, and full source code for several example savers. Overview Screen savers start when the mouse and keyboard have been left idle for some time. They have five main purposes: To avoid phosphor burn caused by static images left on the screen. What a saver is A saver is a straightforward executable that has been renamed with the extension .scr, and which responds to particular command-line arguments in particular ways as detailed in the rest of this document. Version differences between '95, Plus! Windows NT does all saver password management itself, and closes savers automatically in response to keyboard or mouse events. Creating a saver This chapter describes the behaviour expected of a saver. How and when saver is executed The following list gives all the situations in which a saver will be launched.

free tutorials Have you ever read through a chapter in one of those Learn Such and Such in 21 Seconds books and realized that somewhere along the way you had started daydreaming about how you would spend a trillion dollars if you were Bill Gates? Well, it happens to me all the time. Computer books are boring. In fact, most technical writing out there bites the big one and there's no sign that the situation is going to get any better in the near future. The really unfortunate thing about this predicament is that now, more than any other period in the history of computing, is when we really need good, clear writing out there. Whether the established priesthood of computer science likes it or not, the web has opened the flood gates and computer science is being secularized post haste. Well, the fact is that most people learning how to make a living on the web are not morons and if given the proper instructions can do just about everything they want to with their web sites, if not more.
