iphone - Inheritance in Objective C -

-

i have main game class renders game using open gl. thought inherit class , call [super init] in init method copy of it. plan make modifications in copy seems doesn't work.

the following header file of class:

#import "gameview.h"   @interface cloneview : gameview {  }  -(id)initwithframe:(cgrect)frame;  @end

and clone view class:

@implementation cloneview  -(id)initwithframe:(cgrect)frame{     return [super initwithframe:frame]; }  @end

if set break point in init method in gameview class stops there. thing is: clone view doesn't rendered, screen stays black. missing? help!

edit record: tried without implementing initframe , got same result. (as expected initframe above isn't doing apart calling super)

edit 2 i'm adding clone view i'm creating 2 eagle contexts. reason why doesn't work?

if not adding in init function of cloneview don't have rewrite it. can have class inherit gameview , automatically copies it's init function.

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. ...
