cocos2dx之CCAccelerometerDelegate

CCAccelerometerDelegate的消息处理机制与win32的消息处理机制一样的，由于篇幅太长，我就不详细解答，CCAccelerMeterDelegate

例子代码如下：

void MyAcceleroMeterLayerTest::initLayer() {
    CCSize size = CCDirector::sharedDirector()->getWinSize();
    m_pSprite = CCSprite::create("ball-hd.png");
    m_pSprite->setAnchorPoint(ccp(0.5f, 0.5f));
    m_pSprite->setPosition(ccp(size.width / 2.0f, size.height / 2.0f));
    this->addChild(m_pSprite, 1);
    m_pSprite->retain();
    this->setAccelerometerEnabled(true);
}   

void MyAcceleroMeterLayerTest::didAccelerate(CCAcceleration* pAccelerationValue) {
    CCDirector *pDir = CCDirector::sharedDirector();
    CCSize winSize = pDir->getWinSize();

    if(m_pSprite == NULL) {
        return;
    }

    CCSize spriteSize = m_pSprite->getContentSize();
    CCPoint ptNow = m_pSprite->getPosition();
    CCPoint ptTemp = pDir->convertToUI(ptNow);

    ptNow.x += pAccelerationValue->x * 9.81f;
    ptNow.y += pAccelerationValue->y * 9.81f;

    FIX_POS(ptNow.x, (spriteSize.width / 2.0f), (winSize.width - spriteSize.width / 2.0f));
    FIX_POS(ptNow.y, (spriteSize.height / 2.0f), (winSize.height - spriteSize.height / 2.0f));
    m_pSprite->setPosition(ptNow);
}
