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],该网站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();
?>
