SWFSprite::add — Adds an object to a sprite
$object
) : void此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担 。
swfsprite::add() adds a swfshape(), a swfbutton(), a swftext(), a swfaction() or a swfsprite() object.
For displayable types (swfshape(), swfbutton(), swftext(), swfaction() or swfsprite()), this returns a handle to the object in a display list.
没有返回值。
Apparently this function DOES, in fact, return a value as many of the MING examples show. It is a SWFDisplayItem. Here is an excerpt of an example that appears elsewhere in the MING docs...
<?php
$p = new SWFSprite();
$i = $p->add($s);
$p->nextFrame();
$i->rotate(15);
$p->nextFrame();
?>
