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");

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) { $i->setRatio($n/20); $box->nextFrame(); }
/* this container sprite allows us to use the same action code many times */

$cell->add(new SWFAction("
setTarget('box');

"));
$cell->nextFrame(); $cell->add(new SWFAction("
gotoFrame(0); play();
"));
$cell->nextFrame();
/* finally, add a bunch of the cells to the movie */

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