用 PHP 動態創建 Flash 動畫 (Rate:) （轉）
作者: unknow 發布時間: 2002-7-11 文章類型: 轉載 閱讀次數: 124次 來自: unknow
Macromedia 公司出品的 Flash 動畫軟件現已經成為Web頁面上非常流行的表現工具，網站開發者利用它引起浏覽者的興趣。然而不幸的是，僅僅使用ActionScript創建動畫受到很大的限制，Macromedia已經宣布，打算放棄Flash Generator產品，轉而采用支持Flash MX的Cold Fusion，我們的網站將向何處去呢？現在，我們可以利用Ming PHP庫來輕松地動態創建Flash動畫，並且和我們的代碼無縫集成。我們可以根據數據庫裡的數據創建出各種不同效果的動畫。
Ming 動畫庫最初出現在PHP4.05版本裡，替代了以前版本的LibSwf模塊。Ming 庫采用C編寫，支持多種語言，下面先看一下如何利用PHP來制作動畫。該庫使用簡單，和 PHP 緊密集成，但是，該庫仍然處於實驗階段，目前的版本是0.2a，在線的教程、例子、和幫助手冊可以讓我們方便地學習，Ming裡的函數組織的很有條理，方便PHP和Flash開發者查找。使用 PHP和Ming庫，不但讓我們的網站有華麗的裝飾，而且可以減少開發Flash動畫的費用和繁復的勞動。
使用Ming庫有兩種方式，我們可以內嵌到PHP裡（對Unix平台而言），也可以把它作為一個PHP模塊來運行，裡面的函數支持所有的平台，使用時也無需實例化。如果我們把Ming庫作為PHP模塊來運行的話，我們必須明確地調用Ming庫，和使用其他模塊一樣，然後使用該庫裡的函數。由於使用前必須先加載模塊，與把Ming作為內部函數編譯的方式相比，要有一點性能的下降。
Ming庫是完全免費的，我們可以到創作者的網站下載，地址是：[url]http://www.opaque.net/ming/[/url]，該網站....php.net/ming。
一旦我們正確安裝和配置了Ming庫，我們可以創建一個PHP對象，從PHP裡調用Ming的函數，通過調用函數和屬性，就可以定義我們的動畫了。在PHP模塊裡有13個對象，提供了Flash的一些功能，也有幾個命令可以來控制發行時的參數設定。下面就看看如何利用它來創建動畫。
使用Macromedia Flash創建SWF格式的動畫，我們先創建一些符號，Flash有三種類型的符號：圖形、動畫剪輯、按鈕。一旦我們創建了這些符號，我們就可以把它們復制到場景裡，每一個拷貝稱為一個實例，可以放任意多的實例到我們的場景裡。接下來就可以定義這些對象的行為了，也就是定義動作和運動軌跡，也可以定義動畫的參數，如尺寸大小和背景顏色，如果需要，可以保存成.SWF文件。
利用PHP的Ming庫創建Flash動畫，和Macromedia Flash一樣，必須先創建一些符號，這些符號就是PHP對象的實例，然後定義這些對象在動畫場景裡的位置和相互關系，接著定義對象在每一幀裡的動作，最後定義動畫自己。我們可以直接把SWF直接輸出到浏覽器，也可以保存成SWF格式的文件，以備後用。Flash的優點就是圖形化的用戶接口，利用Ming庫不但可以更加簡單的控制對象，而且具有無限的擴展性和再用性。
下面我們就用一個完整的例子來看看如何使用Ming庫：
<?php
/* 首先創建一個符號，並填充顏色 */
$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);
/* 在動畫剪輯裡使用上面的符號，並添加一些腳本 */
$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);
$sqclip->nextFrame();
}
/* 下面創建按鈕 */
function rect($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);
/* 下面創建動畫，並添加上面的符號和按鈕 */
$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);
/* 最後，我們把它輸出到浏覽器 */
header('Content-type: application/x-shockwave-flash');
$m->output();
?>
