a question about SMSG_MONSTER_MOVE .

[dahe]

void Unit::SendMonsterMoveByPath(Path const& path, uint32 start, uint32 end, uint32 MovementFlags)

{

uint32 traveltime = uint32(path.GetTotalLength(start, end) * 32);

uint32 pathSize = end-start;

WorldPacket data( SMSG_MONSTER_MOVE, (GetPackGUID().size()+4+4+4+4+1+4+4+4+pathSize*4*3) );

data.append(GetPackGUID());

data << GetPositionX( )

<< GetPositionY( )

<< GetPositionZ( );

data << GetOrientation( );

data << uint8( 0 );

data << uint32( MovementFlags );

data << uint32( traveltime );

data << uint32( pathSize );

data.append( (char*)path.GetNodes(start), pathSize * 4 * 3 );

//WPAssert( data.size() == 37 + pathnodes.Size( ) * 4 * 3 );

SendMessageToSet(&data, true);

}

From the realdata ,i found that data after "data << uint32( pathSize ) "

is not same as "(char*)path.GetNodes(start), pathSize * 4 * 3 " .

I think it is compressed

But I do know how it be compressed .

can Someone give some infomation ?

a sample
