SWFDisplayItem->rotateTo

Description

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(); ?>
