PHP read ACT file

[CaioVictor]

Hi rAthena ^^'

 

First excuse my English.

 

I have a problem in the PHP code below:

	$this->header = unpack('a2header/cversion/x/SmovementCount', fread($act, 10));

	$this->movements = array();

	for ($nMovement = 0; $nMovement < $this->header['movementCount']; $nMovement++) {
		$movementHeader = unpack('LframeCount', fread($act, 4));

		$this->movements[] = new ActionMovement($movementHeader);

		for ($nFrame = 0; $nFrame < $movementHeader['frameCount']; $nFrame++) {
			fseek( $act, 20, SEEK_CUR );

			$frameHeader = unpack('LlayerCount', fread($act, 4));

			$this
				->getMovement($nMovement)
				->addFrame(new ActionFrame($frameHeader, $this->getSprite()));

			for ($nLayer = 0; $nLayer < $frameHeader['layerCount']; $nLayer++) {
				$layerHeader = unpack('lxOffset/lyOffset/LsprFrame/Lmirror/Cred/Cgreen/Cblue/Calpha', fread($act, 14));

				if($this->header['version'] >= 2){
					$layerHeader += unpack('fxScale', fread($act, 4));
				}else{
					$layerHeader['xScale'] = 0;
				}

				if($this->header['version'] >= 4){
					$layerHeader += unpack('fyScale', fread($act, 4));
				}else{
					$layerHeader['yScale'] = $layerHeader['xScale'];
				}

				$layerHeader += unpack('Lrotation/LsprType', fread($act, 8));

				if($this->header['version'] >= 5){
					$layerHeader += unpack('LxSize/LySize', fread($act, 8));
				}

			}

			$frameData = unpack('LsoundFrame', fread($act, 4));
            
                        extract(unpack('lnumExtraInfo', fread($act, 4)));
                        for( $i=0; $i<$numExtraInfo; ++$i ){
                            $frameData += unpack('x4/VxExtra/VyExtra/x4', fread($act, 10));
                        }
		}
	}

	$this->header += unpack('LsoundCount', fread($act, 4));

	$this->sound = array();

	for ($nSound = 0; $nSound < $this->header['soundCount']; $nSound++) {
		$this->sound[] = array_pop(unpack('a40', fread($act, 28)));
	}

 

This code is working perfectly, including wiki Oboro ACT but in the case of  Kagerou ACT, returns the following error:

Warning: unpack() [<a href='function.unpack'>function.unpack</a>]: Type L: not enough input, need 4, have 0 in ...

 

That is relating the following line:

$layerHeader += unpack('Lrotation/LsprType', fread($act, 8));

 

I know that the code is not the best one, but can anyone help me fix?

 

 

Any help will be greatly appreciated.
 

Att,

CaioVictor.
