Good question, . The answer depends on where your SWF runs.

  • Projector app (.exe/.app): If by "fs command" you mean FSCommand, that is only for standalone projectors. You can toggle fullscreen like this:
// Projector only (not in a browser)
fscommand("fullscreen", "true");   // enter
fscommand("fullscreen", "false");  // exit
  • In a browser: FSCommand will not make the plugin go fullscreen. is right to point you to the Stage API. Two gotchas often missed:
    1. Your HTML embed must allow it:
<!-- OBJECT tag -->
<param name="allowFullScreen" value="true" />

<!-- EMBED tag (if used) -->
<embed ... allowFullScreen="true" />
  1. Entering fullscreen must be triggered by a user action (click, key press). You cannot auto-enter on load, and Esc always exits. If it seems to do nothing, check the permission at runtime:
if (!stage.allowsFullScreen) {
    // Inform the user or adjust your UI (the HTML embed likely lacks allowFullScreen="true")
}

UX tips so it looks right in fullscreen:

  • Control scaling yourself and realign on resize:
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;
stage.addEventListener(FullScreenEvent.FULL_SCREEN, onFullScreenToggle);
stage.addEventListener(Event.RESIZE, onResize);

function onFullScreenToggle(e:FullScreenEvent):void { onResize(); }
function onResize(e:Event = null):void {
    // Reposition/scale your content to maintain aspect ratio, center, etc.
}

Hope that adds the missing context around ’s snippet. And thanks for the nudge to expand on it.

How to get full screen in flash.(fs command)

Have you got any more info??
What exactly are you trying to do?
What version of flash/actionscript are you using?

To make a .swf fullscreen in AS3 you can do this:

stage.displayState = StageDisplayState.FULL_SCREEN;

and to go back to the normal windowed mode you can use:

stage.displayState = StageDisplayState.NORMAL;

NOTE: In order to use StageDisplayState in your AS3, you'll need to make sure you import flash.display.StageDisplayState.

Not sure if that's any help to you, but you haven't exactly given us a lot to go on!

Cheers for now,
Jas.
