SWFDisplayItem->rotateTo (no version information, might be only in CVS) SWFDisplayItem->rotateTo -- Rotates the object in global coordinates Descriptionvoid swfdisplayitem->rotateto ( float degrees ) | Warning | This function is
EXPERIMENTAL. The behaviour of this function, the
name of this function, and anything else documented about this
function may change without notice in a future release of PHP.
Use this function at your own risk. |
swfdisplayitem->rotateto() set the current object
rotation to degrees degrees in global coordinates.
The object may be a swfshape(), a
swfbutton(), a swftext() or a
swfsprite() object. It must have been added using
the swfmovie->add().
This example bring three rotating string from the background to the
foreground. Pretty nice.
Example 1. swfdisplayitem->rotateto() example
<?php
$thetext = "ming!";
$f = new SWFFont("Bauhaus 93.fdb");
$m = new SWFMovie();
$m->setRate(24.0);
$m->setDimension(2400, 1600);
$m->setBackground(0xff, 0xff, 0xff);
// functions with huge numbers of arbitrary
// arguments are always a good idea! Really!
function text($r, $g, $b, $a, $rot, $x, $y, $scale, $string)
{
global $f, $m;
$t = new SWFText();
$t->setFont($f);
$t->setColor($r, $g, $b, $a);
$t->setHeight(960);
$t->moveTo(-($f->getWidth($string))/2, $f->getAscent()/2);
$t->addString($string);
// we can add properties just like a normal PHP var,
// as long as the names aren't already used.
// e.g., we can't set $i->scale, because that's a function
$i = $m->add($t);
$i->x = $x;
$i->y = $y;
$i->rot = $rot;
$i->s = $scale;
$i->rotateTo($rot);
$i->scale($scale, $scale);
// but the changes are local to the function, so we have to
// return the changed object. kinda weird..
return $i;
}
function step($i)
{
$oldrot = $i->rot;
$i->rot = 19*$i->rot/20;
$i->x = (19*$i->x + 1200)/20;
$i->y = (19*$i->y + 800)/20;
$i->s = (19*$i->s + 1.0)/20;
$i->rotateTo($i->rot);
$i->scaleTo($i->s, $i->s);
$i->moveTo($i->x, $i->y);
return $i;
}
// see? it sure paid off in legibility:
$i1 = text(0xff, 0x33, 0x33, 0xff, 900, 1200, 800, 0.03, $thetext);
$i2 = text(0x00, 0x33, 0xff, 0x7f, -560, 1200, 800, 0.04, $thetext);
$i3 = text(0xff, 0xff, 0xff, 0x9f, 180, 1200, 800, 0.001, $thetext);
for ($i=1; $i<=100; ++$i) {
$i1 = step($i1);
$i2 = step($i2);
$i3 = step($i3);
$m->nextFrame();
}
header('Content-type: application/x-shockwave-flash');
$m->output();
?>
