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.
_root.vars.variablename1 = 1
_root.vars.variablename2 = 1
_root.vars.variablename2 = 0
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?

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:
on (release) {
_root.var2 = number(_root.var2) + 1;
_root.var3 = number(_root.var3) - 1;

After some further testing, I found out that under Actionscript 3 XML (E4X) I'm unable to use dynamicaly created variable names...
The famous:
Code:
var i:number = 111
this["someVarName" + i] = "actual_value"
trace(someVarName111) // = actual_value
does not work for me with E4X lingo...
Code:
var myXML:XML
myXML = "...." //asume valid XML content here
trace(myXML.XMLData.@Memo_EN)

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.
