Hi!
Briefly, I have two sprites, one of which is a child of another.
With each sprite related the event listener, as described there.
If both sprites are child nodes of the layer, then everything works great.
Now I need to second sprite is a child node of the first sprite.
But in this case, the second sprite does not respond to events in general.
I’m in a panic and have no idea what’s wrong and how to fix it. Please help.
Here’s a simplified example:
#ifndef __HELLOWORLD_SCENE_H__
#define __HELLOWORLD_SCENE_H__
#include "cocos2d.h"
class HelloWorld : public cocos2d::Layer
{
public:
// there's no 'id' in cpp, so we recommend returning the class instance pointer
static cocos2d::Scene* createScene();
// Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone
virtual bool init();
// a selector callback
void menuCloseCallback(cocos2d::Ref* pSender);
// implement the "static create()" method manually
CREATE_FUNC(HelloWorld);
};
class PlaySprite : public cocos2d::Sprite
{
public:
virtual bool init();
CREATE_FUNC(PlaySprite);
void addEvent();
bool touchBegan(cocos2d::Touch* touch, cocos2d::Event* event);
};
class InPlaySprite : public cocos2d::Sprite
{
public:
virtual bool init();
CREATE_FUNC(InPlaySprite);
void addEvent();
bool touchBegan(cocos2d::Touch* touch, cocos2d::Event* event);
};
#endif // __HELLOWORLD_SCENE_H__
and cpp file
#include "HelloWorldScene.h"
USING_NS_CC;
Scene* HelloWorld::createScene()
{
// 'scene' is an autorelease object
auto scene = Scene::create();
// 'layer' is an autorelease object
auto layer = HelloWorld::create();
// add layer as a child to scene
scene->addChild(layer);
// return the scene
return scene;
}
// on "init" you need to initialize your instance
bool HelloWorld::init()
{
if ( !Layer::init() )
{
return false;
}
Size visibleSize = Director::getInstance()->getVisibleSize();
Vec2 origin = Director::getInstance()->getVisibleOrigin();
// add a "close" icon to exit the progress. it's an autorelease object
auto closeItem = MenuItemImage::create(
"CloseNormal.png",
"CloseSelected.png",
CC_CALLBACK_1(HelloWorld::menuCloseCallback, this));
closeItem->setPosition(Vec2(origin.x + visibleSize.width - closeItem->getContentSize().width/2 ,
origin.y + closeItem->getContentSize().height/2));
auto menu = Menu::create(closeItem, NULL);
menu->setPosition(Vec2::ZERO);
this->addChild(menu, 1);
/////////////////////////////
// 3. add your codes below...
auto sprite1 = PlaySprite::create();
this->addChild(sprite1);
auto sprite2 = InPlaySprite::create();
// !!!

return true;
}

{
