Changing the size a movie clip with action script

1.
'myMovieClip' is the instancename of movieClip which you want to resize. you may replace it with your  movieClip instancename.

2.
'myTargetWidth' is a variable which should be set the the number of pixels you want that movieClip should resize.
for example:
myTargetWidth = 400;

alternatively, you can simply use 400 in place of 'myTargetWidth'


3.
clearInterval(myIntervalIDThatISetEarlier);

above line of code is actually, stopping an setInterval function which is being called repeatedly.

see following link for more details on 'setInterval' and 'clearInterval'

Thanks.  I tried the link, but unfortunately I can't figure out anything from a tutorial until I have an example of exactly what the finished product looks like! so the next part of my question is:
What is "myIntervalIDThatISetEarlier"?  Is that something that has to be defined? If so, where and how is it defined? (I'm sure trhe answer is at the link, but I can't figure it out because I don't understand the meaning of terms like: scope, methodName etc., and although i've read a lot of Flash Help items, it never explains the meaning of these terms in a way that this beginner can understand).

Anyway, I have a movie clip of a rotating suare with the instance name "myMovieClip". And my code  inFrame 1 is:
if (myMovieClip._width < 400px){
  myMovieClip._width++;  // this increments it by one
} else {
 clearInterval(myIntervalIDThatISetEarlier);
}

I get an error message saying that in Frame 1, Line 1: ')' expected, but of course as is typical of Flash errors, it doesn't explain where the ")' goes.
Please let me know exactly what my code should be>

Thanks!

yes, 'myIntervalIDThatISetEarlier' is a normal variable which stores the pointer to a 'setInterval()' object
which is being used as a reference to the running setInterval()

clearInterval() function needs a reference to the setInterval() method to stop it.

hence,
in following line of code 'clearInterval()' method is stopping a setInterval() execution by using its pointer/reference stored in the variable "myIntervalIDThatISetEarlier"

clearInterval(myIntervalIDThatISetEarlier);

I hope it would be clear

Hi Aneesh,
I wish it were clear to me, but it still isn't.
I got rid of the error message by eliminating the px after 400, so now the code has no errors, but it doesn't increase the size of myMovieClip (104px square).

Also, the code doesn't contain the phrase setInterval ... I only see clearInterval() ...... and what do you mean by" it's pointer/reference is stored in the variable "myIntervalIDThatISetEarlier"?  Where is that variable defined?
And are you saying that there is something in the variable "myIntervalIDThatISetEarlier" that is pointin/refering to the clearInterval() method?

Please give me the Action Script exactly as it should appear in my frame action, and tell me everything else I need to do in order for my rotating suare (104 x 104) to increase in size to 400 x 400.

And please forgive my denseness. I started out 2 years ago asking similarly dumb questions about VBA in Excel, and I have actually become quite proficent in that area.

Thanks!
John

CURRENT CODE:
if (myMovieClip._width < 400){
  myMovieClip._width++;  // this increments it by one
} else {
 clearInterval(myIntervalIDThatISetEarlier);
}

I suggest you to upload your sample FLA,
I will review whole existing code and update it according to your requirement

and finally, I will upload the udpated version for your review.

Awesome, thanks aneesh! And thanks for the education.  I'm sure I will have more similar questions today.

Thanks again,
John
