Hello,
New to cocos devlopment, i get seg fault at a particular location. Is there a way to avoid this:
Code: HelloWorldScene.h
_#ifndef HELLOWORLD_SCENE_H
_#define HELLOWORLD_SCENE_H
_#include “cocos2d.h”
_#include “cocostudio/CocoStudio.h”
_#include “ui/CocosGUI.h”
USING_NS_CC;
class HelloWorld : public cocos2d::Layer
{
Sprite *sprite2;
int i;
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();
void update();
// implement the "static create()" method manually
CREATE_FUNC(HelloWorld);
//void leftfn(Sprite *sprite,int i);
};
_#endif // HELLOWORLD_SCENE_H
HelloWorldScene.cpp
_#include “HelloWorldScene.h”
_#include “cocostudio/CocoStudio.h”
_#include “ui/CocosGUI.h”
_#include “cocos2d.h”
USING_NS_CC;
using namespace cocostudio::timeline;
using namespace ui;
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()
{
//////////////////////////////
// 1. super init first
if ( !Layer::init() )
{
return false;
}
auto rootNode = CSLoader::createNode("MainScene.csb");
addChild(rootNode);
auto *sprite1 = (Sprite *)rootNode->getChildByName("bgsprite");
auto *sprite2 = (Sprite *)rootNode->getChildByName("object1");
auto *reset = (Button *)rootNode->getChildByName("Button_1");
auto *left= (Button *)rootNode->getChildByName("Button_2");
auto *right = (Button *)rootNode->getChildByName("Button_3");
//left->setTitleText("This is left");
left->addTouchEventListener([&](Ref* sender, cocos2d::ui::Widget::TouchEventType type){
switch (type)
{
case ui::Widget::TouchEventType::BEGAN:
break;
case ui::Widget::TouchEventType::ENDED:
i++;
//std::cout << "Button 1 clicked" << std::endl;
break;
default:
break;
}
});
//right->setTitleText("This is right");
right->addTouchEventListener([&](Ref* sender, cocos2d::ui::Widget::TouchEventType type){
switch (type)
{
case ui::Widget::TouchEventType::BEGAN:
break;
case ui::Widget::TouchEventType::ENDED:
i--;
//std::cout << "Button 1 clicked" << std::endl;
break;
default:
break;
}
});
//reset->setTitleText("This is reset");
reset->addTouchEventListener([&](Ref* sender, cocos2d::ui::Widget::TouchEventType type){
switch (type)
{
case ui::Widget::TouchEventType::BEGAN:
break;
case ui::Widget::TouchEventType::ENDED:
i = 0;
//std::cout << "Button 1 clicked" << std::endl;
break;
default:
break;
}
});
this->addChild(sprite1);
this->addChild(sprite2);
this->addChild(reset);
this->addChild(left);
this->addChild(right);
update();
return true;
}
void HelloWorld::update()
{
sprite2->setScale(i); //seg fault at this location. if commented app runs normally
}
Thanks.
