Super Easy Email Validation AS2

Admin — Fri, 20 Aug 2010 09:45:21 +0000

I needed a quick and easy way to check for the basics of an email address.

Does it contain “@” and “.” symbols.

This is by no meals a foolproof method, so don’t use it for anything big, but if you want to just do a quick test then here you go:

var email:String = "name@server.com";
if (email.indexOf("@")!=-1 && email.indexOf(".")!=-1) trace("false");

else trace ("true");

Random Number In ASP for no Flash Caching

Admin — Fri, 04 Jun 2010 08:12:37 +0000

This is an example of how to create a random number in Classic ASP in order to append to a swf file so that the browser does not cache the swf file.

<%

Dim SwfRndNum

Randomize

SwfRndNum = Rnd

%>

You can then add it to your swf embed code as follow, bear in mind that I am only showing the snippet around the swf file name and not the entire embed code.

mySwfFile.swf?a=<% Response.Write SwfRndNum %>

Actionscript2: Split string by line length with & without word-wrap

Admin — Wed, 05 May 2010 10:04:25 +0000

Split string into sentences by max line length.
This uses a character array but doesn’t use word-wrapping.

var personalMessage:String = "You got this far so we reckon that you could be curious enough to learn a little more, we’ll contact you shortly to answer any questions you may have.";
_root.myArray = newArray();
_root.myArray = personalMessage.split("");
_root.mySentences = newArray();
var currentCharCount:Number = 0;
var currentCharItem:Number = 0;
var currentCharString:String = "";
var maxLength:Number = 65;
for (var i=0; i<_root.myArray.length; i++ ) {

        if (currentCharCount<maxLength) currentCharString += _root.myArray[i];

        if (currentCharCount==maxLength || currentCharItem==(_root.myArray.length-1)) {

                _root.mySentences.push(currentCharString);

                currentCharCount = 0;

                currentCharString = "";

        }

        currentCharCount++;

        currentCharItem++;

}
trace(_root.mySentences.length);

trace(_root.mySentences[0]);

trace(_root.mySentences[1]);

trace(_root.mySentences[2]);

This outputs the following:

3

You got this far so we reckon that you could be curious enough to

learn a little more, we’ll contact you shortly to answer any que

tions you may have.

Split string into sentences by max line length and use word-wrapping.

_root.myArray = newArray();
_root.myArray = personalMessage.split(" ");
_root.mySentences = newArray();
var currentCharString:String = "";
var maxLength:Number = 60;
for (var i=0; i<_root.myArray.length; i++ ) {

        if (currentCharString.length<maxLength) currentCharString += _root.myArray[i] + " ";
        if ((currentCharString.length >= (maxLength-1)) || (i==(_root.myArray.length-1))) {

                _root.mySentences.push(currentCharString);

                currentCharString = "";

        } else currentCharCount++;

}
trace(_root.mySentences.length);

trace(_root.mySentences[0]);

trace(_root.mySentences[1]);

trace(_root.mySentences[2]);

This outputs the following:

3

Set line leading / line spacing in flash actionscript 2

Admin — Fri, 16 Apr 2010 15:14:40 +0000

This is how to add text leading using Actionscript 2 for Flash.

var txtFormat:TextFormat = new TextFormat();

txtFormat.leading = 5; // change this to whatever you need it to be

ttt.setTextFormat(txtFormat);

ttt2.setTextFormat(txtFormat);span>

There is also a GUI way of doing this:

Select your textfield and and under the paragraph section, set the top/right hand icon (Line Spacing) to whatever you like.

Add a date to a date in Actionscript 2

Admin — Fri, 26 Mar 2010 20:19:42 +0000

I needed to work out a date range according to the date 3weeks away from the current date.
After a bit of thinking, I found that it’s actually quite easy to achieve.

var theDate:Date = newDate();

dateDay = theDate.getDate();

dateMonth = theDate.getMonth();

dateYear = theDate.getFullYear();
var theDate2:Date = new Date(dateYear,dateMonth,dateDay);

theDate2.setDate(theDate2.getDate() + 21);

dateDay2 = theDate2.getDate();

dateMonth2 = theDate2.getMonth();

dateYear2 = theDate2.getFullYear();span>

The above code gets the current date and adds 21days/3weeks to it.
Remember that if you use getMonth to output the final month number, you will want to add 1 to it as it starts at 0;
Example:

dateMonth2 = theDate2.getMonth()+1;

So you would do it like this:

theDate2.getDate() +"/"+ (theDate2.getMonth()+1) +"/"+ theDate2.getFullYear();

Add a month to selectable date range – Date Chooser – Actionscript 2

Admin — Mon, 22 Mar 2010 12:40:20 +0000

I have been working on a project where I need to select a date range starting today and ending a month from now, so the user cannot select anything in the past or over a month from now.

This is how I did it:

There is an instance of DateChooser on the stage with Instance Name “calDate”.

var todayDate:Date = newDate();

dateBeginDay = todayDate.getDate();

dateBeginMonth = todayDate.getMonth();

dateBeginYear = todayDate.getFullYear();
if ((todayDate.getMonth()+1)==12) {

        dateEndDay = todayDate.getDate();

        dateEndMonth = 1;

        dateEndYear = todayDate.getFullYear()+1;

} else {

        dateEndDay = todayDate.getDate();

        dateEndMonth = todayDate.getMonth()+1;

        dateEndYear = todayDate.getFullYear();

}

calDate.selectableRange = {rangeStart: new Date(dateBeginYear, dateBeginMonth, dateBeginDay), rangeEnd: new Date(dateEndYear, dateEndMonth, dateEndDay)}

Animator vs Animation

The Flash plugin is required to view this object.

An animation done showing the battle between animator and the animation in a Flash environment.

Thanks to Alan Becker for this one.

Embed pound symbol (£) in flash textfield

Admin — Wed, 10 Mar 2010 13:55:36 +0000

If you use a dynamic textbox in Flash and you want to embed the British Pound symbol (£) then you will want to also embed the “Latin I” glyphs with your textfield.

Enable / Disable Cursor Hand in Actioncsript 2

Admin — Mon, 01 Mar 2010 14:40:40 +0000

If you have a movieclip that by default has the hand cursor showing on RollOver and you don’t really want this, you can disable it by doing the following:

myMC.onRollOver = function() {

        this.useHandCursor=false;

}

So the main code here is: this.useHandCursor=false;
False disables it and true shows it.

Calling event functions from movieclips in actionscript 2

Admin — Wed, 24 Feb 2010 17:41:03 +0000

In a flash movie I usually have a frame of actionscript that controls all elements in the file to keep everything in one place.

Sometimes I have an onPress(etc) function that refers to something happening in the scene when something is pressed, but what happens if we want another element to refer to that event for some reason?

Here’s an example of that code without anything “flashy”:

_root.myMC.onPress = function() {

        //code goes here

}

..and here’s our slightly more intersting flashy version:

_root.myMC.onPress = _root.funcOnPress = function() {

        //code goes here

}

So now we can call the following from another place in the code to call the same event’s function:

//somewhere else in our flash file

_root.funcOnPress()

That’s about it folks!
Now you can call things from other places.
Just remember to not use “_root” if you are including your final swf inside another swf.
