I declare the header file on aircraft.h to be able to get the variable of ResourceHolder.

Please express yourself clearly, I have no idea what you mean. Make sure you're using the correct terms and illustrate the problem with code, if necessary.

What i mean by this is this

#include "Entity.h"
#include "ResourceHolder.h"

Its on the Aircraft class

class Aircraft : public Entity
{
public:
        enum class Type{
                Eagle,
                Raptor
        };


        Aircraft(Type type, const this_undefined& textures);
        virtual void drawCurrent(sf::RenderTarget &target, sf::RenderStates states) const;
       
private:
        Type mType;
        sf::Sprite mSprite;
};

which i was expecting that i could get the this_undefined variable without any errors.

Im stuck. I tried all that i know. I declare the header file on aircraft.h to be able to get the variable of ResourceHolder.

Another thing is that the code from the link has also this

namespace sf
{
class Texture;
}
namespace Textures
{
enum ID
{
Eagle,
Raptor,
Desert,
};
}
// Forward declaration and a few type definitions
template <typename Resource, typename Identifier>
class ResourceHolder;
typedef ResourceHolder<sf::Texture, Textures::ID> TextureHolder;

which for me doesnt make any sense as it could be declare on resourceHolder alone. So why bother creating another file?

General / Code of sfml book?

Code of sfml book and the actual tutorial is different?

Im on chapter and i got one error where VS can is saying the my TextureHolder is undefined. I cant figure out how to solve it. I declare all the header on my aircraft.h

But when i look on the code of sfml book there is this ResourceIdentifiers. Its not event mentioned in the book

Here is my whole code

#include "Entity.h"
#include "ResourceHolder.h"
class Aircraft : public Entity
{
public:
        enum class Type{
                Eagle,
                Raptor
        };


        Aircraft(Type type, const this_undefined& textures); <--------- this is the error; its undefined
        virtual void drawCurrent(sf::RenderTarget &target, sf::RenderStates states) const;
       
private:
        Type mType;
        sf::Sprite mSprite;
};
 

#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>
#include<assert.h>
#include<map>
#include <iostream>
#include <memory>
using namespace std;

namespace Textures{
        enum class Type{
                Eagle,
                Raptor
        };
}


template<typename Resource, typename Identifier>
class ResourceHolder{
public:
        void load(Identifier id, const std::string &filename);

        template<typename Parameter>
        void load(Identifier id, const std::string &filename, const Parameter &secondParam);

        Resource &get(Identifier id);
        const Resource &get(Identifier id) const;
       

        typedef ResourceHolder<sf::Texture, Textures::Type> this_undenfined;

private:
        std::map<Identifier, std::unique_ptr<Resource>> mResourceMap;
       
};

This is the code im following on the book. But i dont know why the "this_undefined" variable is undefined in my IDE

NOTE: I change it to the word "this_undefined"  to highlight the error

Sorry for being persistent but Is it right to view this scene graph as like a space? where every node is an object?

The scene graph does not represent the world, but rather the scene (i.e. mainly the visualized part of the world). And it's just one of many approaches, which has the advantage of expressing relative transforms very easily.

Thanks.

When you don't understand scene graphs, you should first read about their purpose -- e.g. on Wikipedia or game development articles -- and not a blog describing a specific problem in a specific situation.

Yeah i read the wikipedia but it only view it as a tree data.

There is a text you can read about them: http://home.comcast.net/~tom_forsyth/blog.wiki.html#%5B%5BScene%20Graphs%20-%20just%20say%20no%5D%5D

Hi, Thanks for the link. I somehow understand the scene graph but i cant understand most of the part about traversing. Im just a noobie in game development and have no idea what the author means by that.

Anyway if this scene graph thingy is such a bad idea, I wonder why the author of the SFML book use it. I mean it could be a plus for them for teaching some aspiring developers to use a proper technique which they learned from SFML. But i guest that that only applies to 3D.

General / understanding scene graph better?

Im having a trouble visualizing scene graph in my head. I read some blogs and it said that scene graph is like a stage? If this is right then what is scene node?

In Cs terms its a tree data. But in game how can you visualize it? In SFML book it said

A scene graph contains a root scene node, which exists only once in a world.

The term world makes me think to visualize this scene graph as a world? is this right? So this root scene node is the origin? Like for example the (0,0) top-left coordinate?

I think the codes on SFML is not complete.

The two overloaded get() member functions are generalized using the same principle, that is why they are not listed here. You can refer to the online code base for a complete implementation.

I tried to look at the code sample i downloaded but i still cant find the ResourceHolder class. The book and the online code base is not the same.

Hi,

I cant see the clion option on cmake.

Can you teach me step by step if not too much?

One good thing to do would be learning how to configure projects with CMake as CLion uses it too

Do i need to learn Cmake then?
