写一点cocos2dx+lua的程序

cocos2dx+lua 学习

1.用cJSON 解析JSON

2.创建一个文字标签

CCLabelTTF* label = CCLabelTTF::create(title().c_str(), "Arial", 32);
addChild(label, 1);
label->setPosition( ccp(VisibleRect::center().x, VisibleRect::top().y-50) );        

3.创建一个spring

m_pBall = CCSprite::create("Images/ball.png");
m_pBall->setPosition(ccp(VisibleRect::center().x, VisibleRect::center().y));
addChild(m_pBall);

4.获取舞台

CCDirector* pDir = CCDirector::sharedDirector();

5.获取内容的大小和位置

	CCSize ballSize  = m_pBall->getContentSize();
	CCPoint ptNow  = m_pBall->getPosition();

6.切换场景

CCDirector::sharedDirector()->replaceScene(this);    

7.陀螺仪调用

 setAccelerometerEnabled(true);
 void AccelerometerTest::didAccelerate(CCAcceleration* pAccelerationValue)

8.创建一组菜单

CCMenuItemImage *item1 = CCMenuItemImage::create(s_pPathB1, s_pPathB2, this, menu_selector(ActionManagerTest::backCallback) );
CCMenuItemImage *item2 = CCMenuItemImage::create(s_pPathR1, s_pPathR2, this, menu_selector(ActionManagerTest::restartCallback) );
CCMenuItemImage *item3 = CCMenuItemImage::create(s_pPathF1, s_pPathF2, this, menu_selector(ActionManagerTest::nextCallback));

CCMenu *menu = CCMenu::create(item1, item2, item3, NULL);

menu->setPosition(CCPointZero);
item1->setPosition(ccp(VisibleRect::center().x - item2->getContentSize().width*2, VisibleRect::bottom().y + item2->getContentSize().height/2));
item2->setPosition(ccp(VisibleRect::center().x, VisibleRect::bottom().y + item2->getContentSize().height/2));
item3->setPosition(ccp(VisibleRect::center().x + item2->getContentSize().width*2, VisibleRect::bottom().y + item2->getContentSize().height/2));

addChild(menu, 1);   
```

9.定时任务计度

schedule( schedule_selector(PauseTest::unpause), 3); 

void PauseTest::unpause(float dt)
{
	unschedule( schedule_selector(PauseTest::unpause) );
	CCNode* node = getChildByTag( kTagGrossini );
	CCDirector* pDirector = CCDirector::sharedDirector();
	pDirector->getActionManager()->resumeTarget(node);
}

10.加动画效果，加回调函数

 CCMoveBy* pMove = CCMoveBy::create(2, ccp(200, 0));
CCCallFunc* pCallback = CCCallFunc::create(this, callfunc_selector(RemoveTest::stopAction));
CCActionInterval* pSequence = CCSequence::create(pMove, pCallback, NULL);
pSequence->setTag(kTagSequence);

CCSprite* pChild = CCSprite::create(s_pPathGrossini);
pChild->setPosition( VisibleRect::center() );

addChild(pChild, 1, kTagGrossini);
pChild->runAction(pSequence);

11.循环动画

CCActionInterval* move = CCMoveBy::create(3, ccp(VisibleRect::right().x-130, 0));
CCActionInterval* move_back = move->reverse();

CCActionInterval* move_ease = CCEaseBounceInOut::create((CCActionInterval*)(move->copy()->autorelease()) );
CCActionInterval* move_ease_back = move_ease->reverse();

CCDelayTime *delay = CCDelayTime::create(0.25f);

CCSequence* seq1 = CCSequence::create(move, delay, move_back, CCCA(delay), NULL);
CCSequence* seq2 = CCSequence::create(move_ease, CCCA(delay), move_ease_back, CCCA(delay), NULL);

this->positionForTwo();

m_grossini->runAction( CCRepeatForever::create(seq1));
m_tamara->runAction( CCRepeatForever::create(seq2));

12.颜色层

CCLayerColor *box = CCLayerColor::create(ccc4(255, 255, 0, 255));
box->setAnchorPoint(ccp(0, 0));

13.按tag操作对像

 addChild(sprite, 0, kTagSprite); //add时添加tag
 
CCNode* s = getChildByTag(kTagSprite);

14.手势

virtual void ccTouchesBegan(CCSet *pTouches, CCEvent *pEvent) {CC_UNUSED_PARAM(pTouches); CC_UNUSED_PARAM(pEvent);}
 virtual void ccTouchesMoved(CCSet *pTouches, CCEvent *pEvent) {CC_UNUSED_PARAM(pTouches); CC_UNUSED_PARAM(pEvent);}
 virtual void ccTouchesEnded(CCSet *pTouches, CCEvent *pEvent) {CC_UNUSED_PARAM(pTouches); CC_UNUSED_PARAM(pEvent);}
 virtual void ccTouchesCancelled(CCSet *pTouches, CCEvent *pEvent) {CC_UNUSED_PARAM(pTouches); CC_UNUSED_PARAM(pEvent);}


void MainLayer::ccTouchesEnded(CCSet *pTouches, CCEvent *pEvent)
{
CCSetIterator it = pTouches->begin();
CCTouch* touch = (CCTouch*)(*it);

CCPoint location = touch->getLocation();

CCNode* s = getChildByTag(kTagSprite);
s->stopAllActions();
s->runAction( CCMoveTo::create(1, ccp(location.x, location.y) ) );
float o = location.x - s->getPosition().x;
float a = location.y - s->getPosition().y;
float at = (float) CC_RADIANS_TO_DEGREES( atanf( o/a) );

if( a < 0 ) 
{
    if(  o < 0 )
        at = 180 + fabs(at);
    else
        at = 180 - fabs(at);    
}

s->runAction( CCRotateTo::create(1, at) );
}

15.获取舞台大小

CCSize s = CCDirector::sharedDirector()->getWinSize();

16.加载配置

CCConfiguration::sharedConfiguration()->loadConfigFile("configs/config-test-ok.plist");
CCConfiguration::sharedConfiguration()->dumpInfo();

CCLOG("cocos2d version: %s", CCConfiguration::sharedConfiguration()->getCString("cocos2d.version") );
CCLOG("OpenGL version: %s", CCConfiguration::sharedConfiguration()->getCString("gl.version") );

const char *c_value = CCConfiguration::sharedConfiguration()->getCString("invalid.key", "no key");

bool b_value = CCConfiguration::sharedConfiguration()->getBool("invalid.key", true);

double d_value = CCConfiguration::sharedConfiguration()->getNumber("invalid.key", 42.42);

17.创建配置

CCConfiguration *conf = CCConfiguration::sharedConfiguration();

conf->setObject("this.is.an.int.value", CCInteger::create(10) );
conf->setObject("this.is.a.bool.value", CCBool::create(true) );
conf->setObject("this.is.a.string.value", CCString::create("hello world") );

conf->dumpInfo();

18.CURL使用

CURL *curl;
CURLcode res;
char buffer[10];

curl = curl_easy_init();
if (curl) 
{
    curl_easy_setopt(curl, CURLOPT_URL, "baidu.com");
    res = curl_easy_perform(curl);
    /* always cleanup */
    curl_easy_cleanup(curl);
    if (res == 0)
    {
        m_pLabel->setString("0 response");
    }
    else
    {
        sprintf(buffer,"code: %i",res);
        m_pLabel->setString(buffer);
    }
} 
else 
{
    m_pLabel->setString("no curl");
} 

19.获取当前语言

ccLanguageType currentLanguageType = CCApplication::sharedApplication()->getCurrentLanguage();
switch (currentLanguageType)
{
case kLanguageEnglish:
    labelLanguage->setString("current language is English");

20.CCDataVisitor

CCPrettyPrinter vistor;

// print dictionary
CCDictionary* pDict = CCDictionary::createWithContentsOfFile("animations/animations.plist");
pDict->acceptVisitor(vistor);
CCLog("%s", vistor.getResult().c_str());
CCLog("-------------------------------");

CCSet myset;
for (int i = 0; i < 30; ++i) {
    myset.addObject(CCString::createWithFormat("str: %d", i));
}
vistor.clear();
myset.acceptVisitor(vistor);
CCLog("%s", vistor.getResult().c_str());
CCLog("-------------------------------");

vistor.clear();
addSprite();
pDict = CCTextureCache::sharedTextureCache()->snapshotTextures();
pDict->acceptVisitor(vistor);
CCLog("%s", vistor.getResult().c_str());
