i initialized instance of gamescene class follows

  -(id) init {         if ((self = [super init])) { 

however not give me name of instance

i read in documentation method called initwithname can used tried not work gives me warning:

       in function '-[gamescene init]':        warning: 'cclayer' may not respond '-initwithname:'

update:

hello

i going update code let know have tried solution dosnot seem work yet

in myappdelegate.h have lines of code:

firstly have defined app delegate share other classes

myappdelegate.h

    #define ad  (myappdelegate *)[[uiapplication sharedapplication] delegate] 

and in myappdelegate.m have following code:

gs  = [[gamescene alloc] init];//this gamescene sc = [gs scene]; //this calls method -(id)(scene) [[ccdirector shareddirector] runwithscene: sc]; //runwithscene 

now when tried use gs within other class -for example player.m class-

player.m

gamescene* gs = [ad gs]; //retrieving instance appdelegate [gs updatescorebyamount:5];/calling method "updatescorebyamount" 

the results , guess happens?

the program runs without errors gs instance seems different 1 run appdelegate since method "updatescorebyamount" not affect scene run runwithscene in appdelegate

any idea?

many have tried help

if understanding correctly, need reference instance of gamescene class? if case, depends how object created. creating instance controller class , like:

gamescene *gamescene = [[gamescene alloc] init]; 

here, gamescene reference instance need.
