SWFAction Examples

This simple example will move the red square across the window.

Example #1 swfaction() example


<?php

  $s = new SWFShape();

  $f = $s->addFill(0xff, 0, 0);

  $s->setRightFill($f);



  $s->movePenTo(-500, -500);

  $s->drawLineTo(500, -500);

  $s->drawLineTo(500, 500);

  $s->drawLineTo(-500, 500);

  $s->drawLineTo(-500, -500);



  $p = new SWFSprite();

  $i = $p->add($s);

  $i->setDepth(1);

  $p->nextFrame();



  for ($n=0; $n<5; ++$n) {

    $i->rotate(-15);

    $p->nextFrame();

  }



  $m = new SWFMovie();

  $m->setBackground(0xff, 0xff, 0xff);

  $m->setDimension(6000, 4000);



  $i = $m->add($p);

  $i->setDepth(1);

  $i->moveTo(-500,2000);

  $i->setName("box");



  $m->add(new SWFAction("/box.x += 3;"));

  $m->nextFrame();

  $m->add(new SWFAction("gotoFrame(0); play();"));

  $m->nextFrame();

This simple example tracks down your mouse on the screen.

Example #2 swfaction() example


<?php



  $m = new SWFMovie();

  $m->setRate(36.0);

  $m->setDimension(1200, 800);

  $m->setBackground(0, 0, 0);



  /* mouse tracking sprite - empty, but follows mouse so we can

     get its x and y coordinates */



  $i = $m->add(new SWFSprite());

  $i->setName('mouse');



  $m->add(new SWFAction("

    startDrag('/mouse', 1); /* '1' means lock sprite to the mouse */

  "));



  /* might as well turn off antialiasing, since these are just squares. */



  $m->add(new SWFAction("

    this.quality = 0;

  "));



  /* morphing box */

  $r = new SWFMorph();

  $s = $r->getShape1();



  /* Note this is backwards from normal shapes.  No idea why. */

  $s->setLeftFill($s->addFill(0xff, 0xff, 0xff));

  $s->movePenTo(-40, -40);

  $s->drawLine(80, 0);

  $s->drawLine(0, 80);

  $s->drawLine(-80, 0);

  $s->drawLine(0, -80);



  $s = $r->getShape2();



  $s->setLeftFill($s->addFill(0x00, 0x00, 0x00));

  $s->movePenTo(-1, -1);

  $s->drawLine(2, 0);

  $s->drawLine(0, 2);

  $s->drawLine(-2, 0);

  $s->drawLine(0, -2);



  /* sprite container for morphing box -

     this is just a timeline w/ the box morphing */



  $box = new SWFSprite();

  $box->add(new SWFAction("

    stop();

  "));

  $i = $box->add($r);



  for ($n=0; $n<=20; ++$n) {

    $i->setRatio($n/20);

    $box->nextFrame();

  }



  /* this container sprite allows us to use the same action code many times */



  $cell = new SWFSprite();

  $i = $cell->add($box);

  $i->setName('box');



  $cell->add(new SWFAction("



    setTarget('box');



    /* ...x means the x coordinate of the parent, i.e. (..).x */

    dx = (/mouse.x + random(6)-3 - ...x)/5;

    dy = (/mouse.y + random(6)-3 - ...y)/5;

    gotoFrame(int(dx*dx + dy*dy));



  "));



  $cell->nextFrame();

  $cell->add(new SWFAction("



    gotoFrame(0);

    play();



  "));



  $cell->nextFrame();



  /* finally, add a bunch of the cells to the movie */



  for ($x=0; $x<12; ++$x) {

    for ($y=0; $y<8; ++$y) {

      $i = $m->add($cell);

      $i->moveTo(100*$x+50, 100*$y+50);

    }

  }



  $m->nextFrame();



  $m->add(new SWFAction("



    gotoFrame(1);

    play();



  "));



  header('Content-type: application/x-shockwave-flash');

  $m->output();

Same as above, but with nice colored balls...
