ActionScript 2.0 :: Check To See If A Variable Has Been Created?
May 23, 2008
Im creating an online survery and recording all the answers as a variable in _root.vars.variablename where each question creates a new variable in the vars clip.
When the user answers a question the variable is created and given a value e.g.
But I need a piece of code to check if the variable has actually been created. The reason for this is I have a next button the user has to click once they have answered, and I dont want them to advance if they havent answered. So I need to add something like if (_root.vars.variablename1 exists ) {gotoAndPlay("answered");} else{ gotoAndPlay("noAnswer");}
When an instance variable is constructed by a constructor method, why do you need to refer to the current instance variable being created when its the only one being created? I understand assigning an expression to it but why name it "this." when it is the only object that the constructor is building? Does it have some hing to do with being able to naming that object in the Local Variable? In other words am I creating a generic object that will be named in another class?
I urgently need to be able to check the authenticity of a Flash CS4 file. There is no information given about author etc in the properties using Windows but I was hoping that Flash embeds author information and history.
I am trying make a movieclip pan across the stage on a set path, I have 5 buttons, when button 2 is clicked, the movie clip is moved to position 2, its moved on a timeline so a function starts playing the movieclip, on the timeline inside this movieclip there are conditions on specific frames showing where the the timeline stops, so when button2 is clicked a variable is created which is "label2" and the timeline stops on this point, as seen the the condition below[code]....
the "for" loop below creates a grid from xml loaded content.. it first creates a row then populates that row with movieclips. the problem is "row1" creates fine but when it gets to "row2" the information that should be displayed is over written by what is in "row1".. this due to the second running of the inner "for" loop cant create over already set variables by the first running of it:
I searched this a number of times, but I haven't found the answer was.I am new to scripting, so I am still finding what works and doesn't. So far I have added a number of variables in the engine I am creating. I want the player to click the button. Once press it will affect many of variables. The thing is I want to make the button unpressable if one variable is <= a number, lets say 100, and another term is true: number(_root.var2)/number(_root.var1) > 2).Here is what I have so far:
Im looking for something similar to the php function isset where you can check to see if a variable has been set. Does anyone know how i would go about seeing if a value has been set for a Number variable?
I have created a variable that when defined as String can end up containing what I need. It just doesnt do what I need it to do.So I can trace out a1Tap=containa1_ mc.square_ mc. saysquare_btn.That is what I want a1Tap to contain but it isn;t the right kind of data.[code]How do I set up and use the a1Tap variable so that a) it contains containa1_ mc. square_ mc.saysquare_btn (as it currently does)in a way that it work as a path name for an event listener?
I am creating movie clips with a for loop using attachMovie, I would like to pass a variable into the clip itself at the time of it's creation. It seems simple enough, but my little brain is imploding...
So basically I got an MC: "clip"+i, which I would like to pass a variable (from an array), for it to use on it's own timeline. I want the next clip to be able to use the next variable in the array in it's own timeline.
if (XMLData.product[i].image[0].thumb) {thumbURL = XMLData.product[i].image[0].thumb;}Returns: TypeError: Error #1010: A term is undefined and has no properties.Same withif (XMLData.product[i].image[0].thumb!=undefined) {thumbURL = MLData.product[i].image[0].thumb;}
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)
This is the Script:[code]I want to change .cloud to .propName where I'll be able to insert the property I want to check when calling the function.something like this:[code]but it doesn't work, AS3 think the propName is a property.
I was wondering if there a way to check if a variable(x) exist.. Let me try to explain a bit more: Let's pretend i load 5 variables from a text file named myvariable1 , myvariable2, ... , myvariable5 How can i check if "myvariable(x)" = true where x = 1 or 2 or 3 ... as they were incremented..?
I have a frame where there a 5 input text fields that the user can fill in. THey may not fill them all in though. In the next frame I want to push the fields that they filled in into an array.how do I determine what they filled in and what they didn't.

I'm displaying a variable into a textbox, but sometimes it's value is unset (loading delay). I'm using loadVariables so the .onLoad won't work.. How can I check if a variable already has a value?
