Question

I have a parent with two children that I want to communicate with each other. For some reason it is not working. Here is what I have:

Parent

    GameplayLayer *gameplaylayer = [GameplayLayer node]; // 1
    [self addChild:gameplaylayer z:2 tag:1];

    GameplayLayer2 *gameplaylayer2 = [GameplayLayer2 node]; // 1
    [self addChild:gameplaylayer2 z:20 tag:2];

Child

.h

#import "GameplayLayer2.h"

@interface GameplayLayer : CCLayer { 
GameplayLayer2* game;
}

.m

    game = (GameplayLayer2*)[[self parent] getChildByTag:2];

But when I try to run a function in game like so [game runfun] it doesn’t run.

Answer 1

Check in debugger, that after this call

game = (GameplayLayer2*)[[self parent] getChildByTag:2];

game instance is not nil
