Pygame Primer, Mark 2 - Movement

A long time ago, in a tutorial far away... Ok, so maybe it hasn't been that long since our last foray into the world of programming, but it sure seems like it sometimes. On a more serious note, however, a while back we did go over some very basic things involving Python and a library known as Pygame. Today my friends, we will be continuing on this path, and adding to what we build that fateful December day.

2,000,000 Visits and Growing

Another year has come and gone here at Switch On The Code and that means it's time to look back at 2009 and how we did. First I have say it was a great year and we really did a lot of new things here. We started podcasting, doing video tutorials, and much more. A new version of the site was launched built completely in Drupal just about 1 year ago exactly. Now I really hope that this year will bring just as many goodies.

Flex Datagrid Percentage Width Columns

I have a multitude of tutorials on the Flex Datagrid here at Switch On The Code and none of them show you how to use percentage widths in your Datagrid. Now at the surface this seems really easy, but the way they implemented it in Flex is very unintuitive. So, today I am going to show you how to quickly get percentage based columns in your datagrid.

C# Tutorial - Using the BackgroundWorker Class

It's a rule that should never be forgotten - don't ever perform work that takes a non-trivial amount of time on the UI thread. Of course you're now wondering, "Where do I perform tasks that take a non-trivial amount of time?". The answer is simple - on a different thread. There are lots of ways to get your work onto another thread, which can include directly creating a Thread or using the ThreadPool.

Using Shark to Performance Tune Your iPhone App

Here was the problem: we were working on an OpenGL iPhone game and for some reason the frame rates were unusually low - especially for what little action was happening on the screen at the time. My first plan of attack was to begin commenting out chunks of the system in an attempt to see what module was causing the problem. I removed the physics, the logic updates, and some of the things being rendered. Nothing I did, however, seemed to create a noticeable improvement in performance.

C++ & Lua - Function Arguments

As we have been realizing here at SOTC, using Lua with C++ is really the only way to make Lua work for you. Lua itself is really not that useful, but used in conjunction with other languages, it can be quite powerful. It past tutorials, we have gone over how to use Lua with C++. However, we have yet to go over how to pass arguments back and forth between the two. This is what we will cover today.

C++ & Lua - Functions

So in our last Lua tutorial, we went over a basic way to get information from lua and use it inside C++ code. This time, we are going to use the same principals to run a lua function from C++ and a C++ function from lua. This opens up endless possibilities for communication between the two. So, how about we get started then.

AppKiDo - Making Cocoa Touch Documentation More Accessible

I enjoy writing applications for the iPhone, not because I like Objective-C or Xcode but I really like seeing the application on my phone. This means I have to endure the other two. Being fairly new to the Cocoa and Objective-C world I spend a fair amount of time in documentation. This is always a mundane task but Xcode just makes it a completely bad experience. Recently I ran across an application that improves the task. The application is called AppKiDo.

Lua & C++ - The Basics

With Lua, almost anything is possible. It is akin to JS, but in some ways it is so much more powerful. With World of Warcraft incorporating Lua right into its core, you have to wonder how powerful you can actually make it. One of the things that make Lua so powerful is its easy integration into C++ and C. With this integration, you can accomplish just about anything. Today, we are going to go through the steps to get some basic interaction between C++ and Lua.

Creating a REST Client using WCF

A couple of weeks ago we received an email about consuming a REST service in WCF. Well, this tutorial should answer that email. Today we're going to build a simple client for Twitter's REST API using WCF. Since it doesn't look like WCF natively support OAuth authentication, the client we're going to write will do one simple thing - request the latest status updates for a specific user. I'm going to write a command line application that asks for a username and then prints a bunch of status updates along with information about the user. Below is some example output.

Lua - Simple Tables

Anyone who plays World of Warcraft and does even the slightest of development knows that Lua is an integral part of its core. It is so important in fact, that Lua can be interpreted from right inside the game itself. Now, besides WoW, Lua is used throughout the gaming world in a host of ways, typically for the UI. This makes Lua something some of us would like to learn about. Today, we are going to take the first step in Lua development and going over the powerful table.

jQuery Snippet - The e.preventDefault() Function

Using the mouse in jQuery is really easy, and opens up a whole new world for those who use javascript. But, just about everything already has a mouse event attached to it. Images are especially tricky, usually allowing click-and-dragging by default. Today we will go over a useful function that will help you take control over just what the mouse button does on certain elements.
