ios - xcode4 parameter of incompatible type -

-

a project runs fine on xcode3, fails compile on xcode4 error:

file://localhost/users/ishaq/projects/game01/libs/cocos2d/cclayer.m: error: semantic issue: sending 'cccolor4b' (aka 'struct _cccolor4b') parameter of incompatible type 'cicolor *'

the code throws error below (from cocos2d-iphone cclayer.m):

+ (id) layerwithcolor:(cccolor4b)color {      return [[[self alloc] initwithcolor:color] autorelease]; }

somehow xcode thinks code calling - (id)initwithcolor:(cicolor *)color; of ciimage (inside ciimage.h). how can set xcode's brain straight? ;-)

i've got same problem. resolution explicitly cast proper type helps compiler find proper class. code looks this:

return [[(cccolorlayer*)[self alloc] initwithcolor:color] autorelease];

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.
