I'm using Rapidjson
to retrieve data from a file, and I want to use that file data to create entities in my game. So, my file has the definition of what a certain entity is (in this case, each ship parameters and components to be created). File looks like follows (for a single ship called dreadnought):
{
"dreadnought" : {
"parameters": {
"image": "data/dreadnought/dreadnought_ship.png",
"linearSpeed" : 10,
"angularSpeed" : 20,
"energy" : 20,
"hitpoints" : 50
},
"components" : {
"primaryWeapon" : {
"name" : "fusionBlaster",
"energyConsumed" : 2,
"cooldown" : 5
},
"secondaryWeapon" : {
"name" : "laserBots",
"energyConsumed" : 2,
"cooldown" : 5
},
"ai" : {
"name" : "dreadnoughtAI"
}
}
}
}
What I want is to get "dreadnought" as an object into a variable, so then I can keep querying over this variable. Something similar to what you do when parsing an XML with Rapidxml
:
xml_document<> doc;
doc.parse<0>((char*)buffer.ToCString());
xml_node<>* rootNode = doc.first_node();
xml_node<>* innerNode = rootNode->first_node("x");
What I can't get is that innerNode
. I would want something like:
rapidjson::Object dreadnought;
dreadnought.HasMember("parameters");
...
I've tried to create an object this way, but I can't find what should I put inside template, and I don't even know if this GenericObject
is what I need:
rapidjson::GenericObject<false, typename ValueT> dreadnought = m_doc["dreadnought"].GetObject();
Thanks in advance.
Okay, I've casually found something which can work for now, although I still have to check if it is enough for what I want.
const rapidjson::Value &dreadnought = m_doc["dreadnought"];
for (rapidjson::Value::ConstMemberIterator itr = dreadnought.MemberBegin();
itr != dreadnought.MemberEnd(); ++itr) {
std::cout << "name : " << itr->name.GetString() << std::endl;
}
This way, each time I call the function which contains that code, it shows:
name : parameters
name : components
So this is what I wanted.
