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：
<?php
/* 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<24; $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();
?>
