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 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]....
View 2 RepliesI 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;

View 5 RepliesIm 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");}

Is there a way to write an "ANY" conditional statement? For example, I want to write an IF statement that if the user presses ANY of 10 specified keys, I want to execute the same bit of code.However, the only ways I know to accomplish this is by

I was wondering if it's possible to show a notification for new updates in a swf file.
Like what if I upload a .txt file somewhere and inside it there's a variable, something like;
Code:
newupdate="Version 2.0 is ready for download at domainname.com."
And this will show up in a text field somewhere in my swf file. Is this possible? Are there any pros and cons about using this method of notification?
(Using Flash CS5, AS2)
I'm converting an old AS2 file into AS3 (and trying to learn AS3 at the same time).A movie clip contains a number of different animated sequences and buttons within the application trigger these different sequences.The buttons are functional only when an animation has completed playing.
In AS2, I achieved this with a var called _root.animating which was initially set to "false" and switched to true when the animation played and switched back to false at the end of the anim sequence. The buttons checked this var when clicked. Here is some of the AS2.[code]...
