2 TileMapObject的使用

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：
