System / SFML string conversion to stl string fail

« on: August 11, 2010, 11:33:47 pm »

What is the relation between your Console class and fstream? Can you show the relevant code (ie. the line which fails to compile), and the error that you get?

If all you want is the internal text of a sf::String as a std::string, you can do that:

Code: [Select]

sf::String Text;
...
std::string = Text.GetText();

it compiles but it wont create the file with the text. but if i use cin it will work fine! idk thats what i did and it wont open it with fstream and  create my map file. the consoel doesnt have a relation with fstream the level class handles streamin.

Level.cpp: (in level::save and load)

Code: [Select]


#include"headers.hpp"
#include"level.hpp"

Config::Config(string file)
{
    File = file;

    string temp;
    ifstream config;
    config.open( file.c_str() );

    while(config>>temp)
    {
        if(temp == "Map_x")
        {
            config>>x;
        }
        if(temp == "Map_y")
        {
            config>>y;
        }
    }
    config.close();
}

System / SFML string conversion to stl string fail

« on: August 11, 2010, 02:28:24 am »

how to i use a sfml string with fstream. it didnt work in my code. though i was converting the from stl string to sfml string.


this is the console class

console.hpp:

Code: [Select]

class Console
{
    sf::Shape Rect;
    sf::Font Text_font;

    string buffer;
    int x, y, h, w;
    char get_typed(sf::Event &event);

    void delete_letter();

    void add_text(char l);

    void add_letter(char text);

    public:

    sf::String Text;
    string entered;
    void set_text(string text);

    void clear();
    string get_text();
    bool is_entering();
    void set_entering(bool enter = true);
    bool entering, Cancel;
    void update(sf::Event &event);
    void Draw(sf::RenderWindow &Window);
    Console(int text_size,int o_x, int o_y, int o_h, int o_w, sf::Font &o_font);

    sf::String GetText();
};

console.cpp

Code: [Select]

#include"headers.hpp"

    //cout<<" buffer :"<<buffer<<"."<<endl;
    //cout<<" final :"<<entered<<"."<<endl;
    buffer.clear();
}

void Console::set_entering(bool enter)
{
    entering = enter;
}

bool Console::is_entering()
{
    return entering;
}

string Console::get_text()
{
    return entered;
}

void Console::delete_letter()
{
    buffer.erase(buffer.length() - 1, 1);
}

char Console::get_typed(sf::Event &event)
{
    return (char)event.Text.Unicode;
}

void Console::add_letter(char text)
{
    buffer.insert(buffer.end(),text);
}

void Console::update(sf::Event &event)
{
    if(entering)
    {
        entered = buffer;
        Text.SetText(buffer);
        if(event.Type == sf::Event::KeyReleased)
        {
            if(event.Key.Code == sf::Key::Delete || event.Key.Code == sf::Key::Back)

Graphics / Writing a Map Editor

« on: February 18, 2010, 09:52:47 pm »

i dont want to sound like a complete noob but. im writing a map editor to see my limitations and i've seen my limitations. how do i display my map format on the screen. i use this to load the map:

Code: [Select]

{
ifstream infile;
infile.open(filename.c_str());
for (int k=0; k<LAYER_AMT; k++)
{
for (int j=0; j<MAP_H; j++)
{
for (int i=0; i<MAP_W; i++)
{
int temp;
infile>>temp;
grid[k][i][j].fx = temp*32;
}
}
}
infile.close();
cout<<"Map loaded successfully";
}


displaying it becomes dificult for me and editing in the program.

im going by the format on http://www.moosader.com/tutfiles/Writing_2D_MapEditor.pdf
