Touch Problem

cocos2d-x C++
#1

I want to implemente a game.The ball disappeared by touched with the sound.
(Android platform + cocos2d-2.1beta3-x-2.1.0)

TouchSprite.h

#ifndef __TOUCHABLESPRITE_H__
#define __TOUCHABLESPRITE_H__

#include "cocos2d.h"



class TouchableSprite : public cocos2d::CCSprite ,public cocos2d::CCTargetedTouchDelegate
{
public:
    TouchableSprite();
    virtual ~TouchableSprite();

    static TouchableSprite* touchSpriteWithFile(const char *file);

    bool initWithFile(const char *file);

    virtual void onEnter();
    virtual void onExit();

    cocos2d::CCRect rect();

    bool containsTouchLocation( cocos2d::CCTouch *touch );

    virtual bool ccTouchBegan(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent);
    virtual void ccTouchMoved(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent);

In HelloWorld.cpp..i create a ball.
I can compile,but touch the ball without any reaction.
#2

In your onEnter* functions, invokethis -> setTouchEnabled( true )*

#3

setTouchEnabled is the CCLayer’s method.TouchableSprite inherit from CCSprite and CCTargetedTouchDelegate. i cannot invoke setTouchEnabled in my onEnter() function…
I learn from others,[CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate (this, 0, true);] this sentence is to set touch enabled.

#4

On the layer you place the TouchableSprite object, you need to use setTouchEnabled()
