[Cocos2d-x]视差滚屏效果的实现

视差滚屏效果的实现:

我们在做IOS游戏开发的时候，经常会遇到那种屏幕动的效果，比如跑酷类的游戏，就这这种效果的典型应用。

效果图：

核心代码：

bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !CCLayer::init() )
    {
        return false;
    }

    CCSize screenSize = CCDirector::sharedDirector()->getWinSize();
    CCSprite *para1 = CCSprite::create("parallax1.png");
    CCSprite *para2 = CCSprite::create("parallax2.png");
    CCSprite *para3 = CCSprite::create("parallax3.png");
    CCSprite *para4 = CCSprite::create("parallax4.png");
    para1->setAnchorPoint(CCPointMake(0, 1));
    para2->setAnchorPoint(CCPointMake(0, 1));
    para3->setAnchorPoint(CCPointMake(0, 0.6f));
    para4->setAnchorPoint(CCPointMake(0, 0));
    CCPoint topOffset = CCPointMake(0, screenSize.height);
    CCPoint midOffset = CCPointMake(0, screenSize.height/2);
    CCPoint downOffset = CCPointMake(0, 0);
    CCParallaxNode* paraNode = CCParallaxNode::create();
    paraNode->addChild(para1, 1, CCPointMake(0, 10), topOffset);
    paraNode->addChild(para2, 2, CCPointMake(0, 10), topOffset);
    paraNode->addChild(para3, 3, CCPointMake(0, 10), midOffset);
    paraNode->addChild(para4, 4, CCPointMake(0, 10), downOffset);
    this->addChild(paraNode,2,1);
    
    CCMoveBy*move1 = CCMoveBy::create(3, CCPointMake(0, -160));
    CCMoveBy*move2 = CCMoveBy::create(3, CCPointMake(0, 160));
    CCSequence*sequence = CCSequence::create(move1,move2,NULL);
    CCRepeatForever *repeat = CCRepeatForever::create(sequence);
    paraNode->runAction(repeat);
    
    return true;
}
