用 PHP 动态创建 Flash 动画 (Rate:) （转）
作者: unknow 发布时间: 2002-7-11 文章类型: 转载 阅读次数: 124次 来自: unknow


Macromedia 公司出品的 Flash 动画软件现已经成为Web页面上非常流行的表现工具，网站开发者利用它引起浏览者的兴趣。然而不幸的是，仅仅使用ActionScript创建动画受到很大的限制，Macromedia已经宣布，打算放弃Flash Generator产品，转而采用支持Flash MX的Cold Fusion，我们的网站将向何处去呢？现在，我们可以利用Ming PHP库来轻松地动态创建Flash动画，并且和我们的代码无缝集成。我们可以根据数据库里的数据创建出各种不同效果的动画。
Ming 动画库最初出现在PHP4.05版本里，替代了以前版本的LibSwf模块。Ming 库采用C编写，支持多种语言，下面先看一下如何利用PHP来制作动画。该库使用简单，和 PHP 紧密集成，但是，该库仍然处于实验阶段，目前的版本是0.2a，在线的教程、例子、和帮助手册可以让我们方便地学习，Ming里的函数组织的很有条理，方便PHP和Flash开发者查找。使用 PHP和Ming库，不但让我们的网站有华丽的装饰，而且可以减少开发Flash动画的费用和繁复的劳动。
使用Ming库有两种方式，我们可以内嵌到PHP里（对Unix平台而言），也可以把它作为一个PHP模块来运行，里面的函数支持所有的平台，使用时也无需实例化。如果我们把Ming库作为PHP模块来运行的话，我们必须明确地调用Ming库，和使用其他模块一样，然后使用该库里的函数。由于使用前必须先加载模块，与把Ming作为内部函数编译的方式相比，要有一点性能的下降。
Ming库是完全免费的，我们可以到创作者的网站下载，地址是：[url]http://www.opaque.net/ming/[/url]，该网站....php.net/ming。
一旦我们正确安装和配置了Ming库，我们可以创建一个PHP对象，从PHP里调用Ming的函数，通过调用函数和属性，就可以定义我们的动画了。在PHP模块里有13个对象，提供了Flash的一些功能，也有几个命令可以来控制发行时的参数设定。下面就看看如何利用它来创建动画。
使用Macromedia Flash创建SWF格式的动画，我们先创建一些符号，Flash有三种类型的符号：图形、动画剪辑、按钮。一旦我们创建了这些符号，我们就可以把它们复制到场景里，每一个拷贝称为一个实例，可以放任意多的实例到我们的场景里。接下来就可以定义这些对象的行为了，也就是定义动作和运动轨迹，也可以定义动画的参数，如尺寸大小和背景颜色，如果需要，可以保存成.SWF文件。
利用PHP的Ming库创建Flash动画，和Macromedia Flash一样，必须先创建一些符号，这些符号就是PHP对象的实例，然后定义这些对象在动画场景里的位置和相互关系，接着定义对象在每一帧里的动作，最后定义动画自己。我们可以直接把SWF直接输出到浏览器，也可以保存成SWF格式的文件，以备后用。Flash的优点就是图形化的用户接口，利用Ming库不但可以更加简单的控制对象，而且具有无限的扩展性和再用性。
下面我们就用一个完整的例子来看看如何使用Ming库：


/* 首先创建一个符号，并填充颜色 */
$square = new SWFShape();
$sqfill = $square->addFill(0, 0, 0xff);
$square->setRightFill($sqfill);
$square->movePenTo(-250,-250);
$square->drawLineTo(250,-250);
$square->drawLineTo(250,250);
$square->drawLineTo(-250,250);
$square->drawLineTo(-250,-250);

/* 在动画剪辑里使用上面的符号，并添加一些脚本 */
$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; $n$i->rotate(-15);
$sqclip->nextFrame();
}

/* 下面创建按钮 */

function rect($r, $g, $b) {
$s = new SWFShape();
$s->setRightFill($s->addFill($r, $g, $b));
$s->drawLine(500,0);
$s->drawLine(0,500);
$s->drawLine(-500,0);
$s->drawLine(0,-500);
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);

/* 下面创建动画，并添加上面的符号和按钮 */

$m = new SWFMovie();
$m->setDimension(4000,3000);

$i = $m->add($sqclip);
$i->setDepth(3);
$i->moveTo(1650, 400);
$i->setName("box");

$i = $m->add($b);
$i->setDepth(2);
$i->moveTo(1400,900);

/* 最后，我们把它输出到浏览器 */

header(’Content-type: application/x-shockwave-flash’);
$m->output();
?>
