Hello all,
I, along with a handful of other classmates, was recently interviewed by Pat Peckham from The City Pages. The interview focused on aspects of our WDMD major at school with respect to our Flash and interactive portion of the program. I was very happy and appreciative of the interview and the time Pat took to hear us talk. Following that, I put together some screenshots of the Molotov iScream (iPhone, Android), and a game I worked on over a year ago with Jeff Nehlsen and Joe Motacek called Nanobot Extreme.
As always, it’s a privilege and honor to be part of an awesome program at UWSP, and even better that our local community is curious about the things we do.
I felt like it would be a good opportunity to share the screenshots with you. Enjoy and leave some comments!
ActionScript 3.0, like many other programming languages, contains a number of basic data types commonly known as primitives. ActionScript 3.0 contains five primitive data types, which is far less than other languages like .NET or Java.
|
Data Type |
Function |
|
String |
A character or series of characters |
|
Boolean |
A value that is either true or false |
|
int |
Positive or negative whole numbers |
|
uint |
Positive whole numbers |
|
Number |
Positive and negative whole and real numbers |
Strings
Strings are a very important data type in programming languages that support them. For instance, string value can represent a sentence, a phrase, a word, a letter, or a directory location in an application, all of which are vital to many applications developed.
In the above example, when the value of String str is traced, the output will read This is a string.
Booleans
Booleans are a great way to evaluate whether a statement in code is true or not. A developer can program an application to do something whether or not a statement is true. For example:
The above code will set the Boolean value to false because the value of five is not greater than 6. After that, the second if statement checks to see whether or not the Boolean’s value is set to true or false. Seeing that the Boolean is false, it will return the trace statement in the else statement.
Integers, Unsigned Integers, and Numbers
Flash comes equipped with a small set of numeric data types that allow the flexibility for almost any developer. If a variable needs to store positive whole numbers, then one would use an unsigned integer to store the values. For whole numbers that are positive and negative, using an integer or Number would be ideal. The difference between integers and Numbers is that Numbers can also store real number values whereas integers only store whole numbers. Also, Number data types can store a headache inducing amount of data compared to integers and unsigned integers. Here’s a breakdown of numeric data type values in Flash

Data Type |
Minimum Value |
Maximum Value |

Number |

As you can see, Numbers are great for not only storing real numbers, but also for REALLY HUGE values. Remember, when programming, choose the numeric data type that’s the most ideal for the situation. For example, if you plan on storing numeric whole number values (positive or negative) that aren’t going to contain decimals, then you’re probably best off using integers. Any time decimals or real numbers in general are involved, use Numbers. When you are developing any type of application or animation, you have to keep system resources in mind to the best of your ability. By doing so, this ensures optimal performance on most computers.
As always, source code is available here.
When creating Adobe AIR applications, one of the more important (and easily overlooked) things that people like is System Tray Icons (Windows) or Dock Icons (Mac) for simple user commands such as changing preferences in the application or exiting entirely.
One of the many advantages of using Adobe AIR is the cross platform support, but how does an application know if it’s running on a Windows or Mac platform in order to accommodate a System Tray or Dock icon for each respective environment? The development team behind Adobe AIR have conquered this problem for developers. Within the NativeApplication Class there’s two boolean properties to resolve this problem. The boolean property supportsDockIcon is used to detect whether or not the native operating system supports Dock Icons (Mac) while the other, supportsSystemTrayIcon, is used for Windows based systems.
What can be done, is that an if-else if statement can be written to compensate for both environments. In most cases, you’d want the logic in both parts of the statement to be similar, with the exception of the size of the icon. This way, continuity and consistency is maintained between both platforms.
As you can see, the idea is pretty simple. If the boolean returns true, then the respective statement will execute. If you would like this code expanded on, please let me know. I’d be more than happy to either update the post or write a follow up post on this topic.
Happy coding! 
This video demonstrates how to use the library of code snippets in the latest generation of Flash (CS5). The video showcases how simple it is to code an application without actually having to write the code.
The person narrating the tutorial has a somewhat strong accent, which may be slightly overbearing to some, but the information in this video is well worth the watch!
New posts will be up starting Monday. I’ve been very busy. Really, I have. Monday’s post will highlight some of what I’ve been up to. Catch you on the flipside.
To keep you occupied, check out some of these videos about the upcoming Creative Suite (CS5) from Adobe:
Enjoy, kids. See you soon.
