game crashed on running

cocos2d-x C++
#1

i continue my ported from http://www.raywenderlich.com/4787/how-to-make-a-catapult-shooting-game-with-cocos2d-and-box2d-part-2 (i already done the part 1).
and i use clawoo ported from cocos2d-x ver 1 (i use cocos2dx ver 2) for reference

the game crashed on createTarget and createTargets
Code on HelloWorldScene.cpp

void HelloWorld::createTargets()

    targets.clear();

    targets.push_back(body);

}

and from the HelloWorldScene.h

 void createTargets();
    void createTarget(const char *imageName,
                      cocos2d::CCPoint position,
                      float rotation,
                      bool isCircle,
                      bool isStatic,
                      bool isEnemy);

private:
    std::vector bullets;
    std::vector targets;
    std::vector enemies;

it show no error when compiling but when i run it on device (eq android) it crashed. it something wrong with the code?

#2

Hm, is the app able to find the resources like ‘brick_2.png’?

/miro/

#3

yeah, its able… im still getting crashed on the game….

#4

Is your class derived from any base class like CCLayer?
And if so, do you have an init() class function where you are calling the init() of the base class?

yes… i call the base init from this code

CCScene* HelloWorld::scene()
{
    // 'scene' is an autorelease object
    CCScene *scene = CCScene::create();

    // add layer as a child to scene
    CCLayer* layer = new HelloWorld();
    scene->addChild(layer);
    layer->release();

    return scene;
}

and on HelloWorld::HelloWorld i called the init class

HelloWorld::HelloWorld()
{
    setTouchEnabled( true );
    // init physics
    this->initPhysics();

    schedule(schedule_selector(HelloWorld::update));
}

i think ill put the code on git later… i dunno how to solve it .
