Skipping Frames in a SWF ("swiff")

In some of your applications you may need to use Flash Audio and JavaScript directly, without any prepackaged APIs such as FlashSound JavaScript API. You will enjoy more features, methods, and properties, but you'll have to take care of all the tiny details that are taken for granted when using FlashSound API.

One of the "tiny" details is embedding the sound object. The JavaScript file included in this tip, flashsoundcheck.js, does exactly this, and other stuff. It also checks for Flash plug-ins, and minimum player version.

The following link demonstrates the GotoFrame() Flash method. The syntax is GotoFrame(frameNumber). It activates the frame number specified by frameNumber in the current track. If the data for a requested frame is not yet available, the player goes to the last frame available and stops, yielding unexpected results during playback. The argument frameNumber is zero-based.

Go To Frame 10

Here is the source code:

<SCRIPT LANGUAGE="JavaScript" SRC="flashsoundcheck.js"></SCRIPT>
<A href="javascript://" onclick="javascript:mySwf.GotoFrame(10); return false">Play</a></FONT><P>
<SCRIPT LANGUAGE="JavaScript">
  Flash_embedSWF("animalsounds.swf");
  var mySwf = window.document.sonify;
</SCRIPT>
