Dynamically Add UIScrollbar to Textfield AS3
Posted by Jeff in ACTIONSCRIPT 3.0 on February 17, 2010
This is building off my previous post and adding a scrollbar to the textfield if there are too may tweets to fit in it. You don’t need to load data from a HTTPService but this is helpful for loading data when you don’t know its length ahead of time.
Drop Down Menu with AS3
Posted by Jeff in ACTIONSCRIPT 3.0 on January 26, 2010
Here is a code snippet that I have been using to create dropdown menus from movieclips in actionscript 3. I probably should try to wrap this up in a class as I bust out this snippet whenever I need this functionality. Usually when I have a ‘button’ that I need to have open up a larger movieclip with selectable/dynamic information in it. Would be nice to set a moviclip to be the ‘menu trigger’ (in the example: _sMouseOver) and another to be ‘the target’ (in the example: _sMenu) in a class… Maybe I will work on a class implementation later.

AS3 – Snow Effect
Posted by Jeff in ACTIONSCRIPT 3.0 on January 11, 2010
The best snow script that I have seen thus far. You get great performance even with 1500 different snowflakes in the movie and practically everything is customizable. I will definitely be using this in projects that require a snow affect.
What you can customize:

AS3 – Load XML Document Class Example
Posted by Jeff in ACTIONSCRIPT 3.0 on November 18, 2009
One thing that I do quite often in Flash is load XML. In order to save time, I separated a lot of that code out into external class files. I also created a snippet of code that calls those files in order to save time when I want to use them. (You will need Lee Brimlow’s snippets panel for this to work.)
The LoadXML and LoadURL classes are probably very similar to those found at Learning Actionscript 3 as that is where I learned a lot about this topic previously. Hope you find this helpful!

AS3 – Draw Circle Animation Based on Time
Posted by Jeff in ACTIONSCRIPT 3.0 on November 1, 2009
If you need to perform an animation and have it be standard when viewed across different machines, it is best to use an onEnterFrame event. I had a need in a project recently to draw a circle in a specified amount of time. I had been using the Timer class but found major time discrepancies between running the code locally and running the code in a browser. With some code that Jackson Dunstan provided, I was able to modify the animation so that you can start/stop drawing the circle based on user input. (In the sample provided it is by clicking the stage) I hope this helps someone in a similar situation. Code after the jump…
AS3 – Loading CSS and Fonts
Posted by Jeff in ACTIONSCRIPT 3.0 on October 30, 2009
Working with CSS and fonts in Flash (especially with dynamic text) can be a huge pain. I have come up with a way that makes it a lot easier. What I do is load them up, store a reference to the css file in a global class, and simply refer to that class when you need to use the fonts and css. The css styles dictate which fonts are used where within your application.
This method seems to work out well and saves on file size as you are referring to an instance of the font instead of instantiating it over and over again etc. (You will need the FontLoader class in order for this to work.)

AS3 – Search & Replace a Word
Posted by Jeff in ACTIONSCRIPT 3.0 on October 14, 2009
In a project I was working on recently there was some information coming back from the database that I was displaying in a textfield. I didnt have any control of the text stored in the database and it was saying to ‘click the button above…’ but in this new interface we were designing, the button was below this textfield. I wrote a little function that replaced the word ‘above’ with ‘below’. Code after the break.
AS3 – Uppercase an input textfield’s contents automatically
Posted by Jeff in ACTIONSCRIPT 3.0 on September 25, 2009
Here is a quick snippet on how to automatically set an input textfield’s text to uppercase. (If you do it on the KeyboardEvent.KEY_UP event, the text will initially show as lowercase than change to uppercase.)
1 2 3 4 5 | text_txt.addEventListener(Event.CHANGE, toUpperCase) private function toUpperCase(evt:Event):void { evt.target.text = evt.target.text.toUpperCase(); } |
AS3 – Remove Spaces from a String
Posted by Jeff in ACTIONSCRIPT 3.0 on September 21, 2009
I had a need to remove spaces from a string the other day so I came up with this helper utility and put it in a small Utility class. This could also be used to remove other characters.
1 2 3 4 5 6 7 8 9 10 | package { public class Utility { public static function removeSpaces(str:String):String{ var text_arr:Array=str.split(' '); return(text_arr.join('')); } } } |
Usage:
1 2 3 4 | import Utility; trace(Utility.removeSpaces('Remove All Spaces Please.')); //Output: RemoveAllSpacesPlease. |
Draw a Circle – AS3
Posted by Jeff in ACTIONSCRIPT 3.0 on September 18, 2009
In a project I was on, I had a need to draw a circle in a certain amount of time and it proved to be a bit of a pain. So here is my code (with some ugly comments) that I used to do it.
