先来第一点吧：
-
Node* Node::getChildByName(const std::string& name) const
-
{
-
//这是引擎原来的
-
//CCASSERT(!name.empty(), "Invalid name"); -
// -
//std::hash<std::string> h; -
//size_t hash = h(name); -
// -
//for (const auto& child : _children) -
//{ -
// // Different strings may have the same hash code, but can use it to compare first for speed -
// if(child->_hashOfName == hash && child->_name.compare(name) == 0) -
// return child; -
//} -
//现在修改的
-
CCASSERT(name.length() != 0, “Invalid name”);
-
std::hashstd::string h;
-
size_t hash = h(name);
-
for (const auto& child : _children)
-
{
-
// Different strings may have the same hash code, but can use it to compare first for speed -
if (child->_hashOfName == hash && child->_name.compare(name) == 0) -
return child; -
//兼容老版UI -
Node* node = child->getChildByName(name); -
if (node) -
{ -
return node; -
} -
}
-
return nullptr; -
}
-
以前需要这样写：
-
Node->getChildByName(“xxxxx”)->getChildByName(“xxxxx”)->getChildByName(“xxxxx”)->getChildByName(“xxxxx”)…;
-
现在只需要：Node->getChildByName(“xxxxx”);缺点不能名字不能重复;
- //另外我在引擎上面封装了一层：
- 所有界面全部用一个场景RootScene;
- 画面切换只需移除原来的层，加载现在的，封装层的加载从xml里面自动读取切换层只需要一句话附上核心代码；
-
