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");

1180 Call to a possibly undefined method navigateToURL

1180 Call to a possibly undefined method navigateToURL

If you get the above error when trying to run your flash actionscript 3 file, you are obviously trying to use the navigateToURL() function but have not imported the flash.net library code.

The following code before everything will correct the problem.

import flash.net.*;

..or a more of a direct unbloated method is as follows:

import flash.net.navigateToURL;

How to use a Timer in Actionscript 3

Admin — Thu, 10 Jun 2010 09:16:47 +0000

It is really easy to create a Timer in Actionscript 3.

Instantiate the Timer Class and pass a time in millions of 1000 to it to work in seconds.

var myTimer:Timer = new Timer(1000);

Setup an event listener to call a function.

myTimer.addEventListener("timer", myTimerEventHandler);

Start the Timer.

myTimer.start();

Start the Timer.

function myTimerEventHandler(event:TimerEvent):void {

        trace(myTimer.currentCount+" seconds have passed.");

}

So altogether we have this.

var myTimer:Timer = new Timer(1000);

myTimer.addEventListener("timer", myTimerEventHandler);

myTimer.start();

function myTimerEventHandler(event:TimerEvent):void {

        trace(myTimer.currentCount+" seconds have passed.");

}

Now you know how to use a Timer in Actionscript 3.

Actionscript 2 & PHP Data Transfer

Admin — Mon, 17 May 2010 11:09:32 +0000

In the below example we will use Actionscript 2 to call a remote PHP file that will return data to it.
It is a simple way of transferring data between the server and client.

Actionscript 2 Code:

callRemoteFile = function(ourVariable:String) {

        var result_lv:LoadVars = new LoadVars();

    result_lv.onLoad = function(success:Boolean) {

                if (success) {

                        if (result_lv.message=="success")

                                trace("done! "+result_lv.returnValue);

                        else

                                trace(result_lv.message);

                } else {

                        trace("Error connecting to server");

                        return false;

                }

    };

    var send_lv:LoadVars = new LoadVars();

    send_lv.ourVariable = ourVariable;

    send_lv.sendAndLoad("http://www.andrewodendaal.com/example/file.php", result_lv, "POST");

}

callRemoteFile("some text here");

PHP Code:

        if (isset($_POST)) echo "a=1&message=success&returnValue=".$_POST["ourVariable"]."&b=2";

        else echo "a=0&message=failed&returnValue=nothing&b=1";

?>

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.

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 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

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.

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.

Error 1046: Type was not found or was not a compile-time constant: Event.

Admin — Mon, 29 Mar 2010 20:10:48 +0000

Error 1046: Type was not found or was not a compile-time constant: Event.

You need to import the Event class!

import flash.events.Event

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)}

if (mc.hitTest(_root._xmouse, _root._ymouse, true))) {

        trace("hitTest Run");
