Notes to Lesson 11

Below is an example of using a red button to rotate a blue square, obtained from techrepublic.com.

<?php
$square = new SWFShape();
 
$sqfill = $square->addFill(0, 0, 0xff);
$square->setRightFill($sqfill);
 
$square->movePenTo(-25,-25);
$square->drawLineTo(25,-25);
$square->drawLineTo(25,25);
$square->drawLineTo(-25,25);
$square->drawLineTo(-25,-25);

//Now we can use that shape in a movie clip and define some actions:
$sqclip = new SWFSprite();
$i = $sqclip->add($square);
$i->setDepth(1);
$sqclip->setframes(25);
$sqclip->add(new SWFAction("stop();"));
 
$sqclip->nextFrame();
$sqclip->add(new SWFAction("play();"));
 
for($n=0; $n<24; $n++) {
$i->rotate(-15);
      $sqclip->nextFrame();
}
/*
Next we'll create another shape and use it for a button. Rather than create a separate shape for each button action (over, down, up, and release), I've created a function to automate drawing the shapes:
*/
function rect($r, $g, $b)  {
$s = new SWFShape();
$s->setRightFill($s->addFill($r, $g, $b));
$s->drawLine(50,0);
$s->drawLine(0,50);
$s->drawLine(-50,0);
$s->drawLine(0,-50);
return $s;
}
 
$b = new SWFButton();
$b->addShape(rect(0xff, 0, 0), SWFBUTTON_UP | SWFBUTTON_HIT);
$b->addShape(rect(0, 0xff, 0), SWFBUTTON_OVER);
$b->addShape(rect(0, 0, 0xff), SWFBUTTON_DOWN);
 
$b->addAction(new SWFAction("setTarget('/box'); gotoandplay(2);"), SWFBUTTON_MOUSEDOWN);
/*
Next, we define the movie and place the movie clip (sprite) and the button in the movie itself:
*/
$m = new SWFMovie();
$m->setDimension(400,300);
 
$i = $m->add($sqclip);
$i->setDepth(3);
$i->moveTo(165, 40);
$i->setName("box");
 
$i = $m->add($b);
$i->setDepth(2);
$i->moveTo(140,90);
/*
Finally, we send the output to the browser:
*/
header('Content-type: application/x-shockwave-flash');
$m->output();
$m->save("Note11.swf");
?>
