1 CCTMXObjectGroup的使用方法

为了取以下内容：

操作代码如下：

T27TileMapObject.h

#ifndef __T27TileMapObject_H__

#define __T27TileMapObject_H__

#include "cocos2d.h"

#include "cocos-ext.h"

#include "TBack.h"

USING_NS_CC;

USING_NS_CC_EXT;

//格子地图对象层

class T27TileMapObject :public TBack

{

public:

CREATE_FUNC(T27TileMapObject);

bool init();

static CCScene* scene();

};

#endif

T27TileMapObject.cpp

#include "T27TileMapObject.h"

CCScene* T27TileMapObject::scene()

{

CCScene* scene = CCScene::create();

T27TileMapObject *layer = T27TileMapObject::create();

scene->addChild(layer);

return scene;

}

bool T27TileMapObject::init()

{

TBack::init();

CCTMXTiledMap * map = CCTMXTiledMap::create("MarioMap1.tmx");

addChild(map);

//这里的objects是MarioMap1.tmx中的一个key

CCTMXObjectGroup* objGroup = map->objectGroupNamed("objects");

CCArray* objs = objGroup->getObjects();

CCObject* obj;

CCTexture2D* texture = CCTextureCache::sharedTextureCache()->addImage("Mushroom0.png");

CCSpriteFrame* frame = CCSpriteFrame::createWithTexture(

texture, CCRectMake(0,0,texture->getContentSize().width / 4,texture->getContentSize().height));

CCARRAY_FOREACH(objs,obj)

{

//通过下面的方式获得object中的参数信息

CCDictionary* dict = (CCDictionary*)obj;

const CCString* name = dict->valueForKey("name");

const CCString* type = dict->valueForKey("type");

const CCString* x = dict->valueForKey("x");

const CCString* y = dict->valueForKey("y");

if (type->m_sString =="mushroom")

{

//创建一个蘑菇怪Mushroom0.png

CCSprite* sprite = CCSprite::createWithSpriteFrame(frame);

map->addChild(sprite);

sprite->setPosition(ccp(x->intValue(),y->intValue()));

sprite->setZOrder(10000);

}

//如果object对象的名字是Birthday，那么将执行以下的操作

if (type->m_sString =="BirthPoint")

{

CCSprite* sprite = CCSprite::createWithSpriteFrame(frame);

map->addChild(sprite);

sprite->setPosition(ccp(x->intValue(),y->intValue() - 16));

//如果不设置这一句，马里奥会在山后

sprite->setZOrder(10000);

//设置锚点

sprite->setAnchorPoint(ccp(0,0));

}

return true;

}

运行结果：
