However, whether an interval runs more or less often than the frame rate of a movie,

interval times are by no means guaranteed. In an actual test movie, the intervals in

Table R-16 may execute at frames 5 and 9, or even at frames 4 and 9. Code execution,

Player rendering, and available system resources can all affect the actual timing of inter-

vals. Where time is an important factor in an application (for example, in a game),

functions should be written to account for variance in interval times.

Usage

There is no JavaScript-style setTimeout() function in ActionScript. To emulate setTimeout(),

create an interval function that clears itself the first time it runs, as shown in the following

Example.

Example

The following code shows a simple timer that executes after 5 seconds and never executes

again:

function timesUp () {

trace("Time's up!");

// Stop the timer

clearInterval(timerInterval);

}

timerInterval = setInterval(timesUp, 5000);
