Question

I have two class files hudlayer.m and actionlayer.m

I have a method named jump in hudlayer.m
And i have a method named jumpone in actionlayer.m

-(void) jumpone {
    _heroBody->ApplyLinearImpulse(b2Vec2(_playerVelX/[_lhelper pixelsToMeterRatio], 1.25), _heroBody->GetWorldCenter()); 
}

and another method called jump in hudlayer.m

-(void)jump {
   ActionLayer *aob = [[ActionLayer alloc] init]; 
   [aob jumpone];
}

The problem is when i call the Jumpone method from actionlayer.m my sprite jumps (i.e method called)

My init method of action layer

- (id)initWithHUD:(HUDLayer *)hud
{
    if ((self = [super init])) {

        [self setupWorld]; 
    }
    return self;
}

But when i call jumpone via jump method in from hudlayer.m it fails and my app crashed.
Any help will be appreciated .thanks

Answer 1

the best solution for your problem is to add a tag to hudlayer & action layer

ex: hudlayer.tag=1;
actionlayer.tag=2;

and then just use getChildByTag like this:

[[[[CCDirector sharedDirector]runningScene] getChildByTag:1]jumpone];
