cocos2d-X中CCNode的CCTouch事件

我试图搜索，但找不到想要的答案，有人能告诉我CCNode的CCTouch事件是什么吗？正如我们已经为CCLayer创建了cctouchStart、CCTouchMoved和cctouchEnd，CCLayer是CCNode的子类，所以您可以使用所有相同的函数

像这样的

HelloWorldScene.h

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

HelloWorldScene.cpp

bool HelloWorld::ccTouchBegan(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent){ 
printf("ccTouchBegan");

return true;
}

void HelloWorld::ccTouchMoved(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent){
printf("ccTouchMoved");
}
void HelloWorld::ccTouchEnded(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent){
printf("ccTouchEnded");
}
void HelloWorld::ccTouchCancelled(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent){
printf("ccTouchCancelled"); 
}

CCNode无法检测触摸事件。触摸事件仅由CCLayer检测，CCLayer继承自CCNode，因此它具有CCNode的所有属性和检测触摸事件的额外功能

---

您可以查看我的博客，这是一个新开始的博客，我将一篇一篇地介绍所有cocos2d-x内容。

您必须继承CCTouchDeligate类和CCNode 查看CCLayer.cpp中的CCLayer:：registerWithTouchDispatcher（）函数 您可以将CCNode添加到CCTouchDispatcher

CCTouchDispatcher* pDispatcher = CCDirector::sharedDirector()->getTouchDispatcher();
pDispatcher->addStandardDelegate(this, 0);

完成此操作后，您将收到对的回调

void ccTouchesBegan(...), ccTouchesMoved(...), ccTouchesEnded(...)

---

CCNode的子类也可以接收触摸事件。

假设您的子类名称为MyNode。 它必须实现--

CCTouchOneByOneDelegate方法以接收单触事件

CCTouchAllAtOnceDelegate接收多点触控事件

注意：您要添加CCNode的这个支持触摸的子类的层，在向Touch dispatcher注册该层时不应吞下触摸

类接口：

#import <Foundation/Foundation.h>
#import "cocos2d.h"
#import "CCProtocols.h"

@interface MyNode : CCNode <CCTouchOneByOneDelegate,CCTouchDelegate>//Implementing only for single touch events
{
   @private  CGSize  winSize;
}
+(MyNode*) addMyNodeToParentClass:(CCNode*)parent;

如果MyNode需要实现多点触控事件，请实现CCTouchAllAtOnceDelegate的委托方法---

有人能给我推荐一个大家都知道cocos2d-x的博客吗？

#import "SettingsMenu.h"
@implementation SettingsMenu

+(MyNode*) addMyNodeToParentClass:(CCNode*)parent;
{
    return [[self alloc]initWithParentNode:parent];
}

-(id)initWithParentNode:(CCNode*)parent
{
    if(self=[super  init])
    {
         winSize=[CCDirector sharedDirector].winSize;

        //Registering MyNode with the TouchDispatcher
        [self registerWithTouchDispatcher];


        //adding a single sprite to check touch events
        CCSprite *sprite=[CCSprite spriteWithFile:@"information.png"];
        infoButton.position=ccp(winSize.width/2,winSize.height/2);
        [self addChild:infoButton];

        //adding this node to the parent node
        [parent addChild:self];
     }
      return self;
}

#pragma function registering with Touch Dispatcher
-(void)registerWithTouchDispatcher
{
    [[CCDirector sharedDirector].touchDispatcher addTargetedDelegate:self priority:INT_MIN+1 swallowsTouches:YES];//if any other node needs this touch do not swallow this touch

}

#pragma -CCTouchOneByOne delegate methods

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{

    CGPoint touchPoint=[[CCDirector sharedDirector] convertTouchToGL:touch];

    if(CGRectContainsPoint(infoButton.boundingBox, touchPoint))
    {

        printf("\nTouch received on information button");
    }

    return  YES;
}

-(void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event
{
    CGPoint movedTouchPoint=[[CCDirector sharedDirector] convertTouchToGL:touch];
    //your code to handle touch-movement

}
-(void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event

     //your code to handle touch-end
}

-(void)ccTouchCancelled:(UITouch *)touch withEvent:(UIEvent *)event
{
    //handle event for incoming SMS,Call ect.
}

#pragma -method to remove Touch Dispatcher
