Delegates Tutorial (C#) This tutorial demonstrates the delegate types. It shows how to map delegates to static and instance methods, and how to combine them (multicast). Sample Files Further Reading Tutorial A delegate in C# is similar to a function pointer in C or C++. A delegate declaration defines a type that encapsulates a method with a particular set of arguments and return type. An interesting and useful property of a delegate is that it does not know or care about the class of the object that it references. Note Delegates run under the caller's security permissions, not the declarer's permissions. This tutorial includes two examples: Example 1 shows how to declare, instantiate, and call a delegate. In addition, it discusses the following topics: Delegates and Events Delegates vs. Example 1 The following example illustrates declaring, instantiating, and using a delegate. The use of delegates promotes good separation of functionality between the bookstore database and the client code. Output Code Discussion
Apprenez à développer en C# Vous avez entendu parler du langage C, du C++, et voilà qu'on vous présente maintenant le C# ! Encore un langage me direz-vous ? Oui, mais pas n'importe lequel ! Il existe beaucoup de langages de programmation, comme le C, le C++, Python, Java... Le C# (Prononcez "Cé charpe" ou "ci charpe" à l'anglaise), vous en avez peut-être entendu parler autour d’un café, ou bien rencontré un développeur qui en vantait les mérites ou peut-être vu une offre d’emploi intéressante sur le sujet… qui sait ? Bref, vous avez envie de découvrir et d'apprendre le C#. C’est justement l’objectif que se donne ce tutoriel. En lisant les chapitres les uns après les autres, vous : commencerez à découvrir ce qu'est vraiment le C#verrez les applications informatiques que nous pouvons réaliser avec et comment ce langage s'intègre dans un ensemble plus importantapprendrez réellement la syntaxe du C#découvrirez comment travailler avec des données afin de manipuler des fichiers ou de lire et écrire dans une base de données
Design Pattern A design pattern in architecture and computer science is a formal way of documenting a solution to a design problem in a particular field of expertise. The idea was introduced by the architect Christopher Alexander in the field of architecture[1] and has been adapted for various other disciplines, including computer science.[2] An organized collection of design patterns that relate to a particular field is called a pattern language. The elements of this language are entities called patterns. Each pattern describes a problem that occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice. — Christopher Alexander[1] The usefulness of speaking of patterns is to have a common terminology for discussing the situations designers already see over and over. Overview[edit] A pattern must also explain when it is applicable. See also[edit]
tiny code / minimalistic programming / yagni / kiss / dry How to make an Adventure Game This article will cover what goes into the programming of an adventure game. The ideas will mostly be implementation agnostic but where code is provided or implementation specifics are discussed they use the Engine project from my book C# Game Programming as a base. All the code is available online under the MIT license. The ideas covered here are widely applicable, navigation meshes very much like the one described are used in games such as Baulder's Gate, Planescape Torment etc. and with very little tweaking such navigation meshes can be used for 3D games, inventory and dialogue systems are also common in games with RPG elements. What are Point and Click adventure games? Point and click adventure games were a popular genre of games in the early 1990s and have recently started to make a bit of a come back. Moving the mouse across items in the scene will highlight their names. Next to the commands panel there's an inventory panel which shows what Guybrush is currently carrying. 1.
Top 10 Truly Bizarre Programming Languages Technology This is a list of some of the most bizarre programming languages you will ever see. These types of languages are usually called “Esoteric Programming Languages”. An esoteric programming language (sometimes shortened to esolang) is a computer programming language designed either as a test of the boundaries of programming language design, to experiment with weird ideas or simply as a joke, rather than for practical reasons. There is usually no intention of the language being adopted for real-world programming. Such languages are often popular among hackers and hobbyists. Usability is rarely a high priority for such languages; often quite the opposite. Many fascinating and unlikely languages have been developed, and there is a small but active Internet community of people creating, programming in and debating them. A “Hello World” program has traditionally been the first program most people learn in a language that is new to them. Pictured above is “Hello World” in Whitespace.
C# Tutorial: Dot Net Perls How to market your app yourself and take it front page 30 May 2013 Last updated at 20:31 ET By Fiona Graham Technology of business reporter, BBC News Do it yourself: Having a PR firm on retainer can set you back upwards of £3,000 a month - unthinkable for the smallest start-ups. Don't panic. There's a lot you can do for yourself You've had an idea. During those long cold days spent at the allotment, tending your prize turnips, you considered how lonely the life of a turnip fancier can be. If only there was a way to meet like-minded souls, perhaps when you were out and about? And so is born your marvellous app idea. Fast forward several months and having found a root vegetable loving developer and designer at the annual TurnipCon, it's ready to ship. Well, almost. Shameless self-promotion The days when a nifty idea, a few good reviews and a pretty icon for the app store were all you needed to take your app to Angry Birds status are long gone. It's estimated that 56bn smartphone apps will be downloaded in 2013 . Don't panic. The perfect pitch
Sonic Physics Guide - Sonic Retro ROM Hacks make the process of developing a functional Sonic game with unique art, enemies, and modifications much easier, since the game engine and basic mechanics are already functional. However, if the game requires a different game engine, modifying existing low-level assembly may be inappropriate, and some game designers might choose to program their own unique game engine. The physics of a game engine are rules that describe how to transform the player's input (either in the form of buttons, keyboard, or even a mouse if the designer feels inclined) into appropriate changes in the position of the sprites in the game (such as the Sonic sprite, or alternatively, how enemy sprites will respond). These physics guides will hopefully make the process of simulating the rules used in Sonic games easier. Since the rules themselves are independent of how they are implemented, many people choose programming languages such as Java, C, C++, Python, or a Lisp dialect to implement game physics.
