I am using CCTouchTargetedDelegate with a Class subclassed by CCSprite. when defining delegate methods i am not being able to use "this" inside the functions.
as answered on previously asked questions I couldn't used name of class with the function using scope resolution , because it then gave me error of "Out-of-line definition of 'ccTouchBegan' does not match any declaration in 'mygames::DragSprite'"
I also tried to declare the function in .h file but nothing seems to work.
My code is as below :-
.h File
#pragma once
#include "cocos2d.h"
namespace mygames
{
class DragSprite: public cocos2d::CCSprite, public cocos2d::CCTargetedTouchDelegate
{
public:
DragSprite* createWithFile(const char *pszFileName);
bool isTouchingOnSprite(cocos2d::CCPoint touch);
virtual bool init();
bool ccTouchBegan(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent);
static inline cocos2d::CCPoint ccpSub(const cocos2d::CCPoint v1, const cocos2d::CCPoint v2);
private:
bool isDrag;
cocos2d::CCPoint whereTouch;
};
}
.cpp File
#include "DragSprite.h"
using namespace mygames;
bool DragSprite::init()
{
if (!CCSprite::init()) {
return false;
}
whereTouch = cocos2d::CCPointZero;
isDrag = false;
return true;
}
DragSprite* DragSprite::createWithFile(const char *pszFileName)
{
DragSprite *pSprite = new DragSprite();
if (pSprite&&pSprite->initWithFile(pszFileName))
{
cocos2d::CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate(pSprite, 0, true);
pSprite->autorelease();
return pSprite;
}
CC_SAFE_DELETE(pSprite);
return NULL;
}
bool DragSprite::isTouchingOnSprite(cocos2d::CCPoint touch)
{
if (this->boundingBox().containsPoint(touch)) {
return true;
}else
{
return false;
}
}
static inline cocos2d::CCPoint ccpSub(const cocos2d::CCPoint v1, const cocos2d::CCPoint v2)
{
return ccp(v1.x-v2.x, v1.y-v2.y);
}
//CCTargetedTouchDelegate
bool ccTouchBegan(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
cocos2d::CCPoint touchPoint = pTouch->getLocation();
if (this->isTouchingOnSprite(touchPoint)) {
this->whereTouch = ccpSub(this->position, touchPoint);
return true;
}
return false;
}
The Error Screen Shot :-
What am i missing here ?
JUST OUT OF CURIOSITY
AS suggested in the answers, If i use
bool DragSprite::ccTouchBegan
So, Would it still call the delegete function ? or just the function from my DragSprite class. I mean, would the function be still overridden ? well... its the method declared in CCTargetedTouchDelegete. and i guess its an abstract function.
bool ccTouchBegan(
needs to be
bool DragSprite::ccTouchBegan(
You shouldnt need this
in the first place.
