Macromedia Flash is everywhere. No seriously, it is everywhere. Not only is Flash used for online and offline movies, websites, games, and applications but it's also used for DVDs and broadcast television.

In fact, my first few years working with Flash (versions 3 and 4) were dedicated to authoring content for several broadcast animated series. Exporting from Flash to video formats so I could import and edit them on an Avid workstation was my only authoring requirement of Flash. I didn't need to know about Flash for the web, ActionScript, optimization, preloaders, or even buttons. It was analog Flash at its purest and that was the world of Flash that I lived in.

Eventually my Flash world expanded into the online realm of dynamic content when Shockwave.com asked me to develop an online animated series. I quickly learned how Flash was truly the Swiss army knife of design and development tools.

Today some of my clients request that their online content be repurposed for video, so the line between Flash for online and offline content occasionally becomes blurred.

You can do the same for your clients—or for yourself. What you need to do is learn how to set up the Stage so that your Flash project outputs optimally to video, use broadcast-safe colors in your project, and export your project to video.

Well Flash ActionScript loops are tools used to execute a segment of code repeatedly for a number of times or while a certain condition is satisfied. This can save time and effort by not having to type the same code multiple times to repeat a process.

For example, if we wanted to duplicate a movie ten times, without a loop, we would have to type the same code ten times.

Using a loop to do this would reduce the amount of code significantly while generating the same identical result. Below is an example of the same command to duplicate a movie ten times using a loop.
for (i=1;i<11;i++){
duplicateMovieClip ("movie_mc", "new_"+i, i);
}
loop Types

There are three main types of ActionScript loops, the for loop (which we used in the example above), the while loop, and the do-while loop. The for and while loops do exactly the same thing but with different syntax, the do-while loop differs in one small aspect. We will go through all of these types in turn.
The For loop

I think that the For loop is the most commonly used because it is the most compact and the easiest to understand and use. You can use this loop to execute a number of code statements multiple times using this format:
for (counter; condition; action){
statements;
}

The example above shows the syntax used, the counter (i) sets the starting point for your counter, the condition will determine the point at which the loop will have to stop, and the action operate counter to eventually make it make the condition untrue to stop the loop. The code to be repeated is placed with in the curly brackets.

For example, if we want to output some text ten times, we can do it this way.
for (i=1; i<11; i++){
trace ("This code is repeated ten times");
}

In regular words the code above says, start counting i from 1, repeat the code below as long as i is less than 11, and add 1 to i each time the loop is repeated. We start with i as 1, when the code is repeated the first time then the value of i increases by 1 making it equal 2, when the code is repeated again it becomes 3, then 4, 5, 6, 7, 8, 9, and 10. After that it becomes 11, and at that moment the condition is no longer satisfied because i is not less than 11 (i>11), and so the loop ends at that point.
The While loop

The while loop repeats a set of code as long as the condition specified is true.
while (condition) {
statements
}

This looks very similar to a conditional, which execute a code once if the condition is satisfied, but here the code is executed repeatedly instead of just once. If the condition remained true forever, this means the loop will be repeated over and over again forever as well, and that should be avoided at all costs, because an infinite loop will crash the Flash player. So there is usually something within the statements that eventually makes the condition untrue.
var i = 1;
while (i < 5){
trace ("This code is repeated");
i++;
}

In the example above, the code will get repeated as long as i is less than 5, we made sure that i increases by 1 each time the loop is cycled through.

Guru In reality this could be written with only one printf and one scanf
(and no getchar()) - place the prompting string and the input function
inside a while loop that will iterate the loop when a flag variable is
true (or false) depending upon whether you prefer testing positive or
negative conditions... the trick is to initialize the flag to force the
loop to be entered the first time... the input value should be tested
after the scanf with an if statement this if statement should change
the flag to a value that will cause the loop to exit when a valid value
is entered or in the else condition print an error message and leave
the flag alone (so that the LOOP WILL REPEAT and a new value may be
entered).
