ios - Cocos2d 2.0 SimpleAudioEngine stop sound effect in another object -

i trying stop sound effect using simpleaudioengine in cocos2d 2.0.

i have next situation;

farm scene 2 sky layers day/night. these placed sprites, created within layer in scene. have sprite classes other characters (using ray wenderlichs space viking code) placed.

upon touching sky have day alter night, , vice versa, , can start , stop night crickets sound effect using aluint id in farm layer (pollitoslayer.m) .

touching sun sprite (class) has it's own aluint reference can start. want stop when touching sky sprite.

is there way reference aluint of sun class when touching simple non-class sky sprite in same pollitoslayer.m?

my code excerpts below.

to maintain simple, 1 thing can have farm layer own 2 skies (day , night) , have day sky own sun. way when determining touched, can see if current sky's heavily body (e.g. sun) touched. if stop necessary effects , play sun effect. if sky touched can stop heavily body's sound effect (which nil if 1 not playing) before changing day/night cycle , continuing play next set of sound effects. example:

@intereface farmlayer() @property (nonatomic, strong) sky* day; @property (nonatomic, strong) sky* night; @property (nonatomic, weak) sky* currentsky; @end @implementation farmlayer - (void)onenter { [super onenter]; self.day = [...]; self.night = [...]; self.currentsky = self.day; // couldn't think of improve name mean. self.day.skybody = [sun ...]; ... } - (void)cctouchesbegan:(nsset *)touches withevent:(uievent *)event { // pseudo-ish code... // if self.currentsky && self.currentsky.skybody touched // - stop necessary sound effects if playing. // - play sky body audio. // else if self.currentsky touched // - stop necessary sound effects (including self.currentsky.skybody's sound effect). // - if self.currentsky == self.day switch night (and vice versa). // - play necessary sound effects new sky. // - create self.currentsky equal the new sky. } @end

i hope helped. illustration quick 1 assumes lot of stuff , not meant copied , pasted should give thought on how go solving dilemma. allow me know if misunderstood question.

edited:

also forgot mention, each object can have own array of sound files , can have convenience methods start , stop them. illustration assume had array property called audioeffects:

@interface sky() @property (nonatomic, strong) nsmutablearray* audiofilenames; @property (nonatomic, strong) nsmutablearray* audioids; @end @implementation sky - (void)addsoundeffectwithfilename:(nsstring *)filename { if (!filename) { // handle error. return; } if (!self.audiofilenames) { self.audiofilenames = [nsmutablearray array]; } [self.audiofilenames addobject:filename]; if (!self.audioids) { self.audioids = [nsmutablearray array]; } [self.audioids addobject:@0]; } - (void)playallaudioeffects { (int = 0; < [self.audiofilenames count]; i++) { nsstring* audiofile = self.audiofilenames[i]; aluint audioid = [[simpleaudioengine sharedengine] playeffect:audiofile]; self.audioids[i] = [nsnumber numberwithunsignedint:audioid]; } } - (void)stopallaudioeffects { (int = 0; < [self.audioids count]; i++) { aluint audioid = [self.audioids[i] unsignedintegervalue]; [[simpleaudioengine sharedengine] stopeffect:audioid]; } } @end
