Python equivalent of Perl's 'w' packing format -

-

what format should use in struct.unpack decode data packed in perl using w format character (as doc says 'ber compressed integer')?

i don't believe python's struct module has support format, supports encodings commonly found in c structs. ber & der encodings encountered within asn.1 encoded streams... 1 of python asn.1 modules might helpful in case (i should note not user-friendly).

if not, may have implement decoder yourself. following bit of code read off int, , return in string unpacking should pick at...

def decode_ber_int(data, offset):     value = 0     while true:         tmp = ord(data[offset])         value = (value<<7) | (tmp&0x7f)         offset += 1         if tmp & 0x80 == 0:             break     return value, offset

sadly, require breaking unpack call unpack, decode_ber_int, , unpack rest.

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
