How can I test a undefined variablewith an if statement.
all a this did not work and I don't want to define a value for this variable.
name of the variable x.
if ((x == "") || (x == " ") (x == Nan))
{
trace("here");
}
Someone could find me the correct if statemtn to check an undefined variable on action script 1, mx 6..develloped with MX2004Pro.
we have this variable from the internet, val(0), in a dynamic text field we can see a digit from this variable. but when we use this variable in actionscript and test it with trace, the variable shows as undefined.how can we make this work without it coming up as undefined??

Is it possible to do a statement such as if(string == undefined) { }?I'm pulling the strings from XML. I'm just trying to not have to go through and put x=" " for each empty childNodes in the XML where this variable isn't necessary.

I want to declare a variable on the main timeline that can be called from anywhere in my movie. So, _global var should be the right approach. I want to declare a movie clip 'MC1' "open", or "closed" so that when it is revisited, my flash file knows the user has been there before and performs a different task from the one it does when 'MC1' was first encountered. So, i need a 'if' statement to run from the variable, when the playhead encounters the movieClip.

I have installed Flash CS4 upgrade successfully with Flash CS3 full. I have also installed Flash CS3 full and then CS4 upgrade, but it made no difference. I cannot test an example that uses sound.extract() method. When I test the movie, I get an error message stating "Call to a possibly undefined method extract through a reference with static type flash.media.Sound".

I'm trying to test the _root._currentframe value in an "if" statement, but I want to test it using the frame LABEL, not the frame NUMBER.
For example:
on(release) {
if(_root._currentframe != "homePage") {
gotoAndPlay("home");
}
}
I know this works if I put the frame NUMBER instead of the label. But is there a way that I can get it to work with the LABEL?

What I'm trying to do is simply this:
<variable> = mvcShip
var ship1 = _root.attachMovie( <variable>, shipName + _root.getNextHighestDepth(), _root.getNextHighestDepth() );
What i am trying to attempt here is to make the variable equal to the name of an item in my library. (Im using this to use different ships in an old arcade-style vertical shooter). This is meant to make a ship appear on stage.
When <variable> is replaced with a library item (eg. mvcShip), it works fine, but if the variable is in place, i get a trace value of ship1 as "undefined", and the ship doesnt show up on the stage.
I have a movie clip on the main timeline that includes a button.When pressed, I want this button to conduct an if statement to check the contents of a textbox on the main timeline and if equal execute the statement.So far I have this but the text does not seem to 'read'. Do I need to pass the textbox contents into a string variable rather than read directly from what is in teh text?[code]

if I use in statement xml-child distinct of nameWin (summa, e. g.), it works good. But with nameWin, e4x compares local variable nameWin (which not interested for me at all at this time) with "necessary name" instead of compare item's nameWin with "necessary name".
i am trying to find out if it is possible to check on more than one variable in an if statement at a time as i am usure how, so is it possible in as2 to check on more than one varialble if answer is equal to the number 1 and answer is to the number two and also the number three perform a function
var answer1:Number =1;
var answer2:Number =2;
var answer3:Number =3;
if(answer == 1 ) and answer == 2 and answer ==3);
if(answer == 1 and answer == 2)
I'm trying to set up a test that will tell me whether a variable exists in memory or not.

I have three randomly moving movie clips and one keyboard controlled movie clip which is meant to avoid the tree random flying clips.
I want to do a hit test that basically will do something if anyone of the 3 random clips hit the keyboard controlled clip.
in the hit test i want to be able to have this work for any of the three random clips (flying pumpkins with different instance names, pumpkin1 pumpkin2 pumpkin3). This is all done on an external document class.
I thought about an array but I have no idea really

A break point on the "Okay" line shows that x1 is null but x2 is equal to "<entity id="DRONE" points="100"/>".
If I take the whole block out of the switch statement, both x1 and x2 are equal to the expected xml.
Given this: if(myVar){}, what will pass as true or false?In JavaScript for example, false are values like null, undefined, 0, '' (empty string), false.

I want to have the whole of the argument in an if statement represented by a variable string. Is this possible? I am yet to get the code to work:
Code:

//if statement contained in a for loop which gathers the featureType variables
if(featureLimit){
//Do something

I have a for statement, using an incrementing variable "a." A dynamic amount of herbs are generated, so here is the for statement.
Code:
for(a=1; a<_global.herbAmount+1; a++) {
var herbMC = _root["herb"+a];
trace(herbMC);
}
When I trace "a," it traces 1, 2, 3 or however many numbers there are up to the global herbAmount number. When I trace _root["herb"], _level0.herb pops out. When I add "a" onto _root["herb"], undefined is traced....why?
I am trying to get a high score table set up and I have it all working except for an if statement which decides whether to put a zero in the time or not.
ActionScript Code:
variable declared at the top
var gap:String;
This is getting data that is stored - it works fine except for the underlined "gap" - The "gap" is meant to be calling the variable which has the below if statement
ScoreInputScore.text=String(SpotTheDifferenceGame._minute)+gap+String(SpotTheDifferenceGame._second);
if (SpotTheDifferenceGame._second<10) {
gap=(":0");
} else {
gap=(":");
}
I thought by have the variable called in in the function and having the if statement with gap= it would do the specified text in the dynamic text box. When I put a trace on "gap" it traces with the correct text depending on what the number is but in my dynamic text box it displays as number null number.
// displays like this when trace put on it
:0
// displays like this in dynamic text box

I want to display variable myblock down 10 times and then test it for collison, I am using the variable I to store the blocks, If I manally set the variable i to lets say 1 and 2 and then test for collison it works, but when I use I from the for loop it only detects one object from the array, I think that there is something probably simple missing such as an extra variable, as you can see from the code I am trying to use the' i' to replace for instance addChild(blockarray[1]);
