YAML > XML

[K-Bal]

Anyone who wants to use XML should consider a short look at YAML with libyaml-cpp. It's extremely easy to use (from my game):

-
name: "Small Rat"
model: "hueteotl"
texture: "rat.png"
scale: 2.0
maxhealth: 15.0
maxmana: 0.0
maxvelocity: 20.0
-
name: "Big Rat"
model: "hueteotl"
texture: "rat.png"
scale: 3.0
maxhealth: 25.0
maxmana: 0.0
maxvelocity: 20.0

Factory method:

Code: Select all

KMEntity* EntityFactory::CreateEnemy(const std::string& script, const std::string& type, const ggut::Vector2f& pos)
{
	//TODO: KMEnemy
	KMEntity* temp = new KMEntity();

	std::ifstream fin(script.c_str());
	YAML::Parser parser(fin);

	YAML::Node doc;
	parser.GetNextDocument(doc);

	try
	{
		for(std::size_t num = 0; num < doc.size(); ++num)
		{
			if(doc[num]["name"] == type)
			{
				temp->SetName(type);
				temp->SetMaxHealth(doc[num]["maxhealth"]);
				temp->SetHealth(doc[num]["maxhealth"]);
				temp->SetMaxMana(doc[num]["maxmana"]);
				temp->SetMana(doc[num]["maxmana"]);
				temp->SetModel(doc[num]["model"]);
				temp->SetPosition(pos);
				temp->SetScale(doc[num]["scale"]);
				temp->SetMaxVelocity(doc[num]["maxvelocity"]);
			}
		}
	}
	catch( ... )
	{
		std::cerr << "Failed to load Enemy from YAML file!" << std::endl;
	}

	return temp;
}

Use:

Code: Select all

myRat = myEntityFactory.CreateEnemy("entities/rats.yaml", "Small Rat", Vector2f(150, 150));

Just wanted to share this. I just discovered it one hour ago

Wow... That looks pretty legit =D. I'll have to take a look at it =p.

[M_D_K]

That's pretty awesome, I'll be checking that out later.

Yeah I think I will diffidently use this, looks really clean and easy to use

Do you know any tutorials or documentation on using it as there seems to be little on it.

How would I use this for my maps

This looks very nice and clean, unlike how bloated XML can get.

I took a week long course on Adobe Flex and they were saying this is what will eventually replace XML due to various reasons.

It will replace XML if we (the developers) use it and spread the word

Sorry for being a noob, but could you please explain the set-up as I am not very experienced with command prompt, which is how they explain it.

[GroundUpEngine]

Same here.. I epic fail at working with & setting up new libraries, I tryed to implement it before but gave up straight away lol. But I really want to use yaml properly!

[K-Bal]

What exactly is your problem? What do you need the cmd prompt for?

[thejahooli]

I realised after downloading it that it was just a usual library set-up. I was just a bit thrown off by the How To Build section of the website.

[LeonBlade]

Hmm... I don't see how I could use this for a map structure, doesn't seem... efficient enough?
Should I just do tile by tile?
