I read TMXOrthoZorder of tests, and I find
“<1> m_tamara = CCSprite::spriteWithFile(s_pPathSister1);
<2> map->addChild(m_tamara, map->getChildren()~~>count);
But I think there may not has <3>.In the <1> , the m_uReference of m_tamara is one. And in the <2>. the m_uReference is two.So I don’t know why this must add <3>. thanks.
