Graphics / text wrapping?

« on: December 22, 2009, 05:13:34 am »

How do you get a long string of text to display inside a "box" using the sf::String? I want it to make a new line whenever it runs out of room for the next word so it doesn't go out of the "box"

Is there a simple way to do this?

General / [Solved] question

I'm getting this error

error C2678: binary '=' : no operator found which takes a left-hand operand of type 'const sf::Input' (or there is no acceptable conversion)
        C:\Documents and Settings\SFML-1.5\include\SFML/Window/Input.hpp(129): could be 'sf::Input &sf::Input::operator =(const sf::Input &)'
        while trying to match the argument list '(const sf::Input, const sf::Input)'

while trying to run this line

Code: [Select]

Input.user_input = Game.App.GetInput();

Here's my class and constructor

Code: [Select]

class CInput
{
public:

const sf::Input& user_input;


CInput(sf::RenderWindow &app) : user_input(app.GetInput())
{
};
};

what's going wrong here

General / sf::string

« on: November 19, 2009, 07:32:42 am »

I'm trying to make "selectable text" meaning that when the mouse hovers over the words, it gets highlighted and stuff. However, the text is changing in length. How do I do this?

Is a way to figure out how much pixels each letter is or something?

General / Why?

So, I'm trying to draw a menu screen. Here's the header file and the main.cpp:

Code: [Select]

#include <SFML/Graphics.hpp>


//declarations
#define MENU 1
#define GAME 2
#define END 3

int game_state = MENU;

sf::RenderWindow App(sf::VideoMode::GetMode(1), "SFML Window");

// GRAPHICS

int load_graphics_menu(void)
{

//menu background

sf::Image menu_background;
if (!menu_background.LoadFromFile("data/art/menu/menu_background.bmp"))
{
MessageBox(NULL,
  "Fail to load image from file",
  "Error",
  NULL);

return -1;
} //Load image

sf::Sprite spt_menu_background;
spt_menu_background.SetImage(menu_background);

//menu play button

sf::Image menu_playbutton;
if (!menu_playbutton.LoadFromFile("data/art/menu/menu_playbutton.bmp"))
{
MessageBox(NULL,
  "Fail to load image from file",
  "Error",
  NULL);

return -1;
} //Load image

sf::Sprite spt_menu_playbutton;
spt_menu_playbutton.SetImage(menu_playbutton);
spt_menu_playbutton.SetPosition(475.f, 235.f);

//menu play button highlighted

sf::Image menu_playbutton_hl;
if (!menu_playbutton_hl.LoadFromFile("data/art/menu/menu_playbutton_hl.bmp"))
{
MessageBox(NULL,
  "Fail to load image from file",
  "Error",
  NULL);

return -1;
} //Load image

sf::Sprite spt_menu_playbutton_hl;
spt_menu_playbutton_hl.SetImage(menu_playbutton_hl);
spt_menu_playbutton_hl.SetPosition(475.f, 235.f);

//menu instruction button

sf::Image menu_instructionbutton;
if (!menu_instructionbutton.LoadFromFile("data/art/menu/menu_instructionbutton.bmp"))
{
MessageBox(NULL,
  "Fail to load image from file",
  "Error",
  NULL);

return -1;
} //Load image

sf::Sprite spt_menu_instructionbutton;
spt_menu_instructionbutton.SetImage(menu_instructionbutton);
spt_menu_instructionbutton.SetPosition(426.f, 324.f);

//menu instruction button highlighted

sf::Image menu_instructionbutton_hl;
if (!menu_instructionbutton_hl.LoadFromFile("data/art/menu/menu_instructionbutton_hl.bmp"))
{
MessageBox(NULL,
  "Fail to load image from file",
  "Error",
  NULL);

return -1;
} //Load image

sf::Sprite spt_menu_instructionbutton_hl;
spt_menu_instructionbutton_hl.SetImage(menu_instructionbutton_hl);
spt_menu_instructionbutton_hl.SetPosition(426.f, 324.f);
//menu exit button

sf::Image menu_exitbutton;
if (!menu_exitbutton.LoadFromFile("data/art/menu/menu_exitbutton.bmp"))
{
MessageBox(NULL,
  "Fail to load image from file",
  "Error",
  NULL);

return -1;
} //Load image

sf::Sprite spt_menu_exitbutton;
spt_menu_exitbutton.SetImage(menu_exitbutton);
spt_menu_exitbutton.SetPosition(12.f, 580.f);

//menu exit button highlighted

sf::Image menu_exitbutton_hl;
if (!menu_exitbutton_hl.LoadFromFile("data/art/menu/menu_exitbutton_hl.bmp"))
{
MessageBox(NULL,
  "Fail to load image from file",
  "Error",
  NULL);

return -1;
} //Load image

sf::Sprite spt_menu_exitbutton_hl;
spt_menu_exitbutton_hl.SetImage(menu_exitbutton_hl);
spt_menu_exitbutton_hl.SetPosition(12.f, 580.f);

return 0;
}

//INPUT

int process_input_menu(void)
 
{
sf::Event Event;
    while (App.GetEvent(Event))
    {
        // Window closed
        if (Event.Type == sf::Event::Closed)
            App.Close();

        // Escape key pressed
        if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
            App.Close();
    }
}


main.cpp

Code: [Select]

#include "UltrapingMenu.h"

int main()
{
sf::RenderWindow App(sf::VideoMode::GetMode(1), "SFML Window");

App.Create(sf::VideoMode(1024, 768, 32), "Ultraping", sf::Style::Fullscreen); //Windows creation...somehow, (1) works, (0) doesn't

load_graphics_menu();

while (App.IsOpened() && game_state == MENU)
{
process_input_menu();

App.Clear();

App.Draw(spt_menu_background);
App.Draw(spt_menu_playbutton);
App.Draw(spt_menu_instructionbutton);
App.Draw(spt_menu_exitbutton);

App.Display();
}

    return 0;
}

and here's the errors

Code: [Select]

Compiling...
main.cpp
.\main.cpp(17) : error C2065: 'spt_menu_background' : undeclared identifier
.\main.cpp(18) : error C2065: 'spt_menu_playbutton' : undeclared identifier
.\main.cpp(19) : error C2065: 'spt_menu_instructionbutton' : undeclared identifier
.\main.cpp(20) : error C2065: 'spt_menu_exitbutton' : undeclared identifier

it doesn't make any sense since I obviously declared these in my load_graphics_menu section...why do I keep getting this error?

Also, does anyone have any tips on optimizing my code? It's a bit cumbersome right now and I'm not sure how to do some things. for example, if I wanted to draw a seperate image the the mouse is hovering over the play button, how should I do that? I don't want to use pages of if and thens.
