Notes to Lesson 13

The example for this Lesson can be reversed with the words fading and the background static. This example uses the square function and the font function mentioned in previous notes. I have also added a fade out and fade in feature for the letters, with extra empty frames added in between to slow down the animation.

<?php 
function font($font,$r,$g,$b,$a,$pointsize,$label){
$Font=new SWFFont("$font");
$Text=new SWFText();
$Text->setFont($Font);
$Text->setColor($r,$g,$b,$a);
$Text->setHeight($pointsize);
$Text->addString("$label");
return $Text;
}

function square($r, $g, $b, $a, $W, $H){
$s = new SWFShape();
$s->setLine(1,$r,$g,$b,$a); 
$s->setRIGHTFill($s->addFill($r, $g, $b, $a));
$s->drawLine($W,0);
$s->drawLine(0,$H);
$s->drawLine(-$W,0);
$s->drawLine(0,-$H);
return $s;
}

$myMovie=new SWFMovie(); 
$myMovie->setDimension(300,200); 
$myMovie->setBackground(255,255,255);

$Square=$myMovie->add(square(0,0,255,255,150,60)); 
$Square->moveTo(40,0);

//(font('font',red,green,blue,alpha,pointsize,'text')
$Text1=$myMovie->add(font('Arioso.fdb',255,255,0,255,40,'Hiding')); 
$Text1->moveTo(60,40);

for($i=0; $i<30; $i++){ 
$myMovie->nextFrame(); 
$Text1->multColor(1.0, 1.0, 1.0,1.0-$i/30); 
} 
for($i=0; $i<20; $i++){ 
$myMovie->nextFrame(); 
}
for($i=0; $i<30; $i++){ 
$myMovie->nextFrame(); 
$Text1->multColor(1.0, 1.0, 1.0,$i/30); 
} 
for($i=0; $i<20; $i++){ 
$myMovie->nextFrame(); 
}

header('Content-type: application/x-shockwave-flash');
$myMovie->output();

$myMovie->save("Note13.swf");
