SYNOPSIS
use SWF::Movie;
$m = new SWF::Movie();
$m = SWF::Movie::newSWFMovieWithVersion(8);
DESCRIPTION
SWF::Movie is the root object of your flashfile. It contains all your other objects you want in your movie. Ming supports many Flash4, Flash5 F6,7,8,9.. features.The SWF::Movie object contains information like the flashversion, the size, the frames per second, the background color. Except that, the SWF::Movie behaves like a SWF::MovieClip. It only cannot be added to another SWF::Movie or SWF::MovieClip.
Notice: The version of your flashmovie can be set by the object SWF. See SWF for more details.
METHODS
- $m = new SWF::Movie()
- Creates a Movie object.
- $m = newSWFMovieWithVersion(version)
- Creates a Movie object with version value (e.g. 8) set.
- $displayItem=$m->add($SWFObject)
-
Add an instance of a SWF-object to your current frame. The returnvalue is a SWF::DisplayItem.
Some possible SWF-objects are: SWF::Action SWF::MovieClip SWF::Shape SWF::Sound SWF::Text SWF::TextField SWF::Bitmap SWF::PrebuiltClip $m->add($shape); # possible, but not more accessible for us $shape_1 = m->add($shape); # good instance
- $m->addExport($block, $name)
-
Prepare linkage to Action script code.
$m->addExport($mc, 'mc'); # and later inside action script....: $ac = new SWF::Action("_root.attachMovie('mc','mc1',11);");
- $m->writeExports()
- Export prepared names to Action script.
- remove($displayItem)
-
Removes the given SWF::DisplayItem instance from the current and following frames of the main timeline.
$m->remove($shape_i);
- nextFrame()
-
Finish a frame of the main timeline. New added objects will be added in the next frame.
$m->nextFrame();
- setNumberOfFrames($frames) =item setFrames($frames)
-
Preset the number of frames of the main timeline. n not used frames before finishing the movie will filled with n nextFrame() statements.
If you inserted more nextFrame() commands than you set with setFrames() the setFrames() will be ignored.
$m->setFrames(100);
- $m->setBackground($red,$green,$blue)
-
Set the background in red, green, blue values. Possible value are 0..255 or hexvalues 0x0..0xff.
$m-setBackground(0xff,0x99,0x00); # orange bg $m-setBackground(0,200,255) # green bg
A transparency level isn't available I asume. (In Flash MX/F6?). A transparent background can be set in the HTML-code for Internet Explorer. Please inform the Authors if that is available for nonIE-browsers.
- $m->namedAnchor($label)
- This function adds a named anchor to the movie.
- $m->setDimension(x,y)
-
Set the dimension in pixel.
#ToDo: #min: (0.0,0.0) # ;-) #max: (?,?) #default: (0.0?,0.0?) #Behavior when values <min: ming sets it to min #Behavior when values >max: ming sets it to max $m->setDimension(200,100); $m->setDimension(123.45,67.89);
- $m->setRate(int)
-
Set the playing speed in frames/second.
#ToDo: #min: 0 #max: ? #default: ? #Behavior when value <min: ming sets it to min #Behavior when value >max: ming sets it to max $m->setRate(30);
- $m->protect()
- A feature that prevents only flashnewbies from importing your movie into Macromedias Flash authoring tools. It cannot protect your content from being loaded by other flashmovies, deleting of the protection with a hexeditor or disassembling with tools.
- $m->setSoundStream($soundstream, [$skip])
-
Puts an SWF::SoundStream object as streaming sound into the main timeline.
The optional skip parameter describes the time in seconds to be skiped.
$m->setSoundStream($soundstream);
- $m->streamMp3($filename)
-
Simplifies the setSoundStream(). You only need the filename.
$m->streamMp3("iloveyou.mp3");
Hint: If you want to reuse this sound/mp3 later in this movie, create a reusable SWF::SoundStream object and then put it into setSoundstream().
- $soundinstance = $m->startSound($sound)
-
Play a prepared SWF::Sound object into the main timeline. Returns an object of SWF::SoundInstance.
$sound = new SWF::Sound("loveyoutoo.mp3", SWF_SOUND_MP3_COMPRESSED ); $si = $m->startSound($sound);
- $m->stopSound($sound)
- Stop playing sound.
- $m->labelFrame($string)
-
Gives the current frame a label that can be used by actionscript as anchor. Then you don't have to count your nextFrame() lines anymore. :-)
$m->labelFrame("win"); #ToDo: #max characters of a label??? #What happen if we put there a big string?? #Which characters are allowed??
- $m->setScriptLimits($maxRecursion, $timeout)
- Set limits for resource usage, related to action script. Setting timeout will protect your computer from too long loops and stack overflow. So endless scripts like ``while (1){};'' will be interrupted after timeout seconds. The default recursion depth is 265, the default timeout is 15 seconds.
- $m->defineScene($offset, $name)
- Define scenes for the movies' main timeline using integer value for frame offset and name of the scene.
- $m->setNetworkAccess($flag)
- Sets network / fileaccess policy. If the flag is set to 0 a localy loaded movie will be unable to access the network but is allowed to access local files. If the flag ist set to 1 a localy loaded movie will be unable to access local files but is allowed to access the network. For SWF >= 8: default is 0,
- $m->addMetadata($xml)
- Adds Metadata to the movie: this function inserts a metadata-tag into the movie. Only one metadata-tag can be set to a movie. Metadata is specified as an XML string.
- $m->assignSymbol($character, $name)
- Assigns a symbolic name for a SWF::Character object. Such classes are available for usage in other SWF files and can be referenced from inside the current movie. To assign a symbol to the root movie use NULL as character value.
- $m->setTabIndex($depth, $index)
- Sets tab index for specified depth level.
- $fontchar = $m->addFont($font)
-
Adds a font to a movie. An object of SWF::FontCharacter class returned.
$font = new SWF::Font('Arial.fdb'); $fch = $m->addFont($font);
- $fontchar = $m->importFont($file, $name)
-
Imports a font from an other SWFFile. An object of SWF::FontCharacter class returned.
$fch = $m->importFont('textField.swf', 'Arial337a');
- $m->importCharacter($url, $name)
- Not yet documented (ToDo!)
- $result = $m->replace($item, $block)
-
This method replaces a displayable character with a new one.
Returns 0 on success , -1 else.
$dispitem = $movie->add($shape1); $movie->nextFrame(); print $movie->replace($dispitem, $shape2); $movie->nextFrame();
- $written = $m->xs_output([$compresslevel])
- $written = $m->output([$compresslevel])
-
Writes the SWF::Movie to stdout. This is normally used for webservers/cgi-scripts.
Don't forget to send the ``Content-Type:''-lines before writing out the movie.
The parameter compresslevel is optional. compresslevel between 0 and 9. Higher values will be interpreted as 9. Values smaller 0 mean no compression. By default the SWF::Movie will be send without compression. Notice: compression available since Flash MX(Flash 6). Ming does not check this for you if you write flash4 or flash5 movies.
Unlike xs_output() the output() method prepared for using via webservers (but not limited to webservers).
Both methods return number of bytes written.
- $written = $m->save($filename [, $compresslevel])
- Method saves the SWF::Movie to a file and returns the number of bytes written. The parameter compresslevel is optional. compresslevel between 0 and 9. Higher values will be interpreted as 9. Values smaller 0 mean no compression. By default the SWF::Movie will be saved without compression. Notice: compression available since Flash MX(Flash 6). Ming does not check this for you if you write flash4 or flash5 movies.
