Re: FLASH: using "loop while"

[John Dowdell]

One thing to watch for with any type of repeat loop is that it's best only

for quick things... iterating through a set number of items, etc.


Where people get into trouble is where they use this to lock the

presentation for seconds at a time... waiting for a mouseclick, waiting for

a keystroke, waiting for a file to load, etc. These aren't good, because it

means that nothing else can happen while you're waiting.


Repeat loops are great for short actions that execute quickly. If you're

waiting for something to happen, though, it's generally better to set a

variable and periodically check whether the state has changed, instead.

   (For instance, you might "go to" to branch back and loop over a series

of frames, and one frame checks whether the timer is greater than the value

of a variable.)
