SWFAction Examples
This simple example will move the red square across the window.
Example #1 swfaction() example
<?php
$s = new SWFShape();
$f = $s->addFill(0xff, 0, 0);
$s->setRightFill($f);
$s->movePenTo(-500, -500);
$s->drawLineTo(500, -500);
$s->drawLineTo(500, 500);
$s->drawLineTo(-500, 500);
$s->drawLineTo(-500, -500);
$p = new SWFSprite();
$i = $p->add($s);
$i->setDepth(1);
$p->nextFrame();
for ($n=0; $n<5; ++$n) {
$i->rotate(-15);
$p->nextFrame();
}
$m = new SWFMovie();
$m->setBackground(0xff, 0xff, 0xff);
$m->setDimension(6000, 4000);
$i = $m->add($p);
$i->setDepth(1);
$i->moveTo(-500,2000);
$i->setName("box");
$m->add(new SWFAction("/box.x += 3;"));
$m->nextFrame();
$m->add(new SWFAction("gotoFrame(0); play();"));

This simple example tracks down your mouse on the screen.
Example #2 swfaction() example
<?php
$m = new SWFMovie();
$m->setRate(36.0);
$m->setDimension(1200, 800);
$m->setBackground(0, 0, 0);
/* mouse tracking sprite - empty, but follows mouse so we can
get its x and y coordinates */
$i = $m->add(new SWFSprite());
$i->setName('mouse');
$m->add(new SWFAction("
startDrag('/mouse', 1); /* '1' means lock sprite to the mouse */
"));
/* might as well turn off antialiasing, since these are just squares. */
$m->add(new SWFAction("
this.quality = 0;
"));
/* morphing box */
$r = new SWFMorph();
$s = $r->getShape1();
/* Note this is backwards from normal shapes. No idea why. */
$s->setLeftFill($s->addFill(0xff, 0xff, 0xff));
$s->movePenTo(-40, -40);
$s->drawLine(80, 0);
$s->drawLine(0, 80);
$s->drawLine(-80, 0);
$s->drawLine(0, -80);
$s = $r->getShape2();
$s->setLeftFill($s->addFill(0x00, 0x00, 0x00));
$s->movePenTo(-1, -1);
$s->drawLine(2, 0);
$s->drawLine(0, 2);
$s->drawLine(-2, 0);
$s->drawLine(0, -2);
/* sprite container for morphing box -
this is just a timeline w/ the box morphing */
$box = new SWFSprite();
$box->add(new SWFAction("
stop();
"));
$i = $box->add($r);
for ($n=0; $n<=20; ++$n) {

/* this container sprite allows us to use the same action code many times */
$cell = new SWFSprite();
$i = $cell->add($box);
$i->setName('box');
$cell->add(new SWFAction("
setTarget('box');
/* ...x means the x coordinate of the parent, i.e. (..).x */

/* finally, add a bunch of the cells to the movie */

Same as above, but with nice colored balls...
