SWFDisplayItem->rotateTo -- Rotates the object in global coordinates


void swfdisplayitem->rotateto ( float degrees )


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

=  "ming!";

$f = new SWFFont("Bauhaus 93.fdb");

$m = new SWFMovie();
$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)
$f, $m;

$t = new SWFText();
$t->setColor($r, $g, $b, $a);
$t->moveTo(-($f->getWidth($string))/2, $f->getAscent()/2);

// 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;
$i->scale($scale, $scale);

// but the changes are local to the function, so we have to
    // return the changed object.  kinda weird..

return $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;

$i->scaleTo($i->s, $i->s);
$i->moveTo($i->x, $i->y);


// 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);
