Graphics / Is this possible?

« on: August 13, 2012, 01:56:55 am »

For my collision detection, is it possible to create a sprite and assign it a sf::Rect<int> for collision checking? If this is possible, would it be easier and more simple than comparing the height + width with just a sprite? I know you can use contains to see if two rects are intersecting, but how would I use it with a sprite?

General discussions / Does Code::Blocks have support for C++11?

« on: August 12, 2012, 08:31:36 pm »

I am trying to use Code::Blocks for my SFML engine, but I cannot use some c++11 features such as unique_ptr. It recognizes it, but whenever I try to use it I get an error. Do I need to upgrade my gcc? If so do you guys know to what?

I found out the problem. SFML 2 does not support Xcode's C++11 so, I will have to manually compile my code.

Heres the full error, sorry about that:

"sf::Texture::loadFromFile(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, sf::Rect<int> const&)", referenced from:

ShockEngine::SplashScreenState::SplashScreenState(bool) in SplashScreenState.o

"sf::Window::create(sf::VideoMode, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, unsigned int, sf::ContextSettings const&)", referenced from: ShockEngine::GameEngine::GameEngine(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, unsigned int, unsigned int, unsigned int, bool) in Engine.o

That's all it gives me. And yes, the original examples work.

Sorry to break up you guys's "discussion"  but when I was trying out your code eXpl0it3r, I get 2 errors from the screen.create and the texture loadfromFile. It says this for screen.create:

"sf::Texture::loadFromFile(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, sf::Rect<int> const&)", referenced from:
      ShockEngine::SplashScreenState::SplashScreenState(bool) in SplashScreenState.o

And loadFromFile:

"sf::Window::create(sf::VideoMode, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, unsigned int, sf::ContextSettings const&)", referenced from:
      ShockEngine::GameEngine::GameEngine(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, unsigned int, unsigned int, unsigned int, bool) in Engine.o

I triple checked all your code, and everything is matching, but the problem persists. Any idea what the problem could be? I am using Xcode if that matters at all.

Yeah I was taking some concepts from Game Dev Geek, but the code was really weird and didn't make much sense in some places. I really like how you manage game states, I will probably take the concept of yours and modify it to how I like. Thanks a lot!

General / State Machine and Engine problem

« on: August 03, 2012, 11:30:06 pm »

I'm having some issues with calling a function through an object pointer in my game state class:

    class GameState {
    public:
        virtual void init(Engine*) = 0;
        virtual void cleanUp() = 0;
       
        virtual void pause(Engine*) = 0;
        virtual void resume(Engine*) = 0;
       
        virtual void handleEvents(Engine*) = 0;
        virtual void update(Engine*) = 0;
        virtual void draw(Engine*) = 0;
       
        void changeEvent(Engine* game, GameState* state) {
           
        }
    };

Every single line gives me errors, because of the Engine pointers I'm trying to make. (and yes I have included the Engine.h file) But, when in my Engine.h file when I use the GameState pointers, they work fine:

    class Engine {
    private:
        sf::RenderWindow window;
        sf::Event event;
       
        std::vector<GameState*> states;
       
    public:
        void init();
        void start();
        void cleanUp();
       
        void changeState(GameState*);
        void pushState(GameState*);
        void popState();
       
        void handleEvents();
        void update();
        void draw();
    };

I think it's some sort of initialization problem, once class getting defined before the first, but I don't know how to fix it. Any help is appreciated, thank you for your time.

No it's ok guys, I got the thing sorted out and I threw my old design out and created a new one that actually works lol. Thanks for the help anyways.

Graphics / Resource Manager

« on: July 25, 2012, 05:23:46 pm »

I'm trying to create a resource manager, here's my main abstract class for the other managers to inherit from. I'm trying to use a templated class so it can be generic:

Manager.h:

namespace ShockEngine {
    template<class T> class Manager {
    protected:
        std::map<std::string, T> mediaList;
       
    public:
        virtual T getMedia(const T& fileName) = 0;
    };
}

Here's my texture manager, which is a derived class of Manager:

TextureManager.h:

#include "Manager.h"

namespace ShockEngine {
    class TextureManager: public Manager<sf::Texture> {
    protected:
        std::map<std::string, sf::Texture> textureList;
       
    public:
        TextureManager();
        virtual ~TextureManager();
       
        Manager<sf::Texture> addMedia(const std::string& fileName);
    };
   
    static TextureManager textureManager;
}

When I try to build and run this, 3 errors come up with my static definition of a texturemanager object, saying "Variable type TextureManager is an abstract class" I've tried to rewrite the template, use different techniques, but nothing works.

It works! I can't believe I forgot about loading to a sprite.. lol....

For my texture manager I'm trying load a .png file and it keeps giving me an error.

void Engine::loadTextures() {
        if (textureManager->loadTexture("tileset.png")) {
            rw->draw(textureManager->getTexture("tileset.png"));
        }
}

When I'm trying to draw to the renderwindow (rw) it gives me this error: "No matching member function for call to 'draw'

Heres my .h file of my TextureManager class:

namespace Engine {
    class TextureManager {
    private:
        std::map<std::string, sf::Texture> textureList;
       
    public:
        TextureManager();
        ~TextureManager();
       
        bool loadTexture(std::string fileName);
        sf::Texture getTexture(std::string fileName);
       
    };
   
    static TextureManager* textureManager;
}

And .cpp file:

Engine::TextureManager::TextureManager() {
   
}

Engine::TextureManager::~TextureManager() {
   
}

bool Engine::TextureManager::loadTexture(std::string fileName) {
    sf::Texture tempTexture;
   
    if (!tempTexture.loadFromFile(resourcePath() + fileName))
        return false;
       
    textureList[fileName] = tempTexture;
    return true;
}

sf::Texture Engine::TextureManager::getTexture(std::string fileName) {
    return textureList[fileName];
}

Anybody know what the problem is?

I'm developing on my mac, on xcode, do you know exactly how to link thor in? I have successfully made the libraries  in Cmake.

I'll look into thor. Do you mean by "maps" tilemaps?

Graphics / std::vector or std::map for texture manager

« on: July 23, 2012, 11:54:51 pm »

Hey guys, I'm making a tilemap game, and for the textures (player, tiles, etc) should I use a vector or a map to hold them? I want to assign all the tiles a specific value, like for example water's key would be 1. Which would be better for what I'm doing? I'm thinking map because you can hold the textures with a value, am I right?

All the tiles are going to be the same size which is 16x16 pixels, but thanks for the info
