NAME
SWF::Movie - SWF Movie class
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.
EXAMPLE
3 examples: a regular minimal SWF::Movie, one with all methods and a more interesting. minimal empty example #!/usr/bin/perl -w use SWF::Movie; $m = new SWF::Movie(); $m->nextFrame(); $m->save("emptyminimal.swf"); full empty examples #!/usr/bin/perl -w use SWF::Movie; $m = new SWF::Movie(); $m->setVersion(4); $m->setBackground(0xff,0xcc,0x0); $m->setDimension(200,100); $m->protect(); $m->setRate(30); $m->setFrames(10); # ming fills it automatic with frames $m->nextFrame() $m->save("empty.swf"); streaming example #!/usr/bin/perl -w use SWF("Shape"); SWF::setVersion(6); $m = new SWF::Movie(); $m->setBackground(0xff,0xcc,0x0); $m->setDimension(200,100); $m->setFrames(10); $m->streamMp3("forever.mp3"); $s= new SWF::Shape(); $s->setLine(40,0xff,0xff,0); $s->setRightFill(0xff,0,0); $s->drawLine(50,0); $s->drawLine(0,20); $s->drawLineTo(0,0); $s_1= $m->add($s); $s_2= $m->add($s); $s_1->move(50,40); $s_2->move(10,40); for($i=1;$i<5;$i++) { $m->nextFrame(); $s_2->move(0,10); } $m->nextFrame(); print "Content-type: application/x-shockwave-flash\n\n"; $m->output(9); # with compression level 9 (since flash6)
