objective c - Newbie question -multiple parameters -

-

i trying implement private method takes nsmutabledictionary , player object parameters. private method, place exists in ".m" file.

it declared as

-(void) incrementscore: (nsmutabledictionary*) scoreboard  forplayer: ( player* ) player {

and call follows :

      [ self incrementscore:deucescore forplayer:p];

however,it won't compile -

may not response message -incrementscore:forplayer

i'm not sure error lies - need declare method in ".h" file, or elsewhere in ".m" file, or have got syntax wrong?

the compiler needs find declaration method somewhere before use it. done in 3 way:

  1. declare method in (public) @interface class in .h file .
  2. declare method in class extension (a semi-private @interface, @ top of .m files).
  3. define method somewhere in @implementation before first use of it.

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.
