How to detect the collision of three sprite in cocos2d-x 2.2?

Question

I am new to cocos2d-x and I am implementing my own flappy bird.

Now I am working with the collision detection and I am stuck.

I added the down_pipe sprite and the up_pipe sprite to a parent sprite pipes, and I move the parent shift from right to left.

But when I check the collision by

if (bird->boundingBox().intersectsRect(pipes->boundingBox()))

It doesn't work.

And I try this way:

if (bird->boundingBox().intersectsRect(pipes->getChildByTag(DOWN_PIPE)->boundingBox()) || bird->boundingBox().intersectsRect(pipes->getChildByTag(UP_PIPE)->boundingBox()))

It still doesn't work.

How can I solve the problem? Any advice?

Answer 1

You try this,

        CCRect target = CCRectMake(pipes->getPosition().x - (pipes->getContentSize().width/2),pipes->getPosition().y - (pipes->getContentSize().height/2),pipes->getContentSize().width,pipes->getContentSize().height);

if (bird->boundingBox().intersectsRect(target))
