Graphics / getting color for rectangle shape
« on: April 26, 2018, 12:21:42 am »
I would like to access the color of a rectangle shape I'm drawing but I don't see anything in the api docs that does that, so how would I do this.

Window / Can't draw vector of pointers to window.
« on: April 10, 2018, 10:24:07 pm »
I've been trying to make a vector of objects, so that I can draw all of them to the screen, so I have been using pointers to do that, but when I try to de-pointer the  pointers, it just throws all kinds of errors. Here is my code

General / Object vector not re-adding items
« on: April 06, 2018, 02:31:57 am »
I am currently making a snake game in c++, but have encountered this problem. In order to make my snake, I have been using a vector full of objects of rectangles, and drawing them to where my snake goes. However, I have run into a problem. At first, my snake would be infinite as I would keep drawing more rectangles to put into the vector. However, when I try to clear the vector at the bottom of my program, none of the rectangles get redrawn, and I'm left with a tiny snake on the screen.

Graphics / movement not being drawn

I am currently making a snake game in sfml, however, whenever i try to change the position of the snake, the snake just stops moving, what is a good fix to this problem?

Window / Drawings not being updated to window
« on: April 04, 2018, 04:37:08 am »
I am trying to create a snake game in SFML, and I can't figure out what is happening because the window is not updating with the new position of the snake. Here is my code.

main.cpp
#include <SFML/Graphics.hpp>

sf::RenderWindow windows(sf::VideoMode::getDesktopMode(), "SFML works!",sf::Style::None);
sf::Font fonts;

if(!fonts.loadFromFile("assets/bit.ttf"))
{

std::cerr << "Error loading font" << std::endl;
}

std::string gameScreen = "Main Menu";
    while(windows.isOpen())
    {
        sf::Event event;
       
        while (windows.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
            {
                windows.close();
            }

            {

         snake1.drawSnake(windows);
         snake1.moveForward(windows);

       }
    }
     return 0;

System / How to run a function until an event happens
« on: April 03, 2018, 10:18:11 pm »
I'm creating a game, where I'm drawing a main menu, however, when I try and clear the screen in the function that draws the main menu, it just gets redrawn by the game loop. I also can't draw it only once, as my main menu has some gui animations that I want to keep. So how would i redraw the main menu over and over until the user clicks on one of the buttons.

Here is my code

main.cpp
#include <SFML/Graphics.hpp>
#include <iostream>
#include "write.h"
#include <SFML/Graphics/Font.hpp>
#include "menu.h"
int main()
{
sf::RenderWindow windows(sf::VideoMode::getDesktopMode(), "SFML works!",sf::Style::None);
sf::Font fonts;

if(!fonts.loadFromFile("assets/bit.ttf"))
{

std::cerr << "Error loading font" << std::endl;
}


    while (windows.isOpen())
    {
        sf::Event event;
        while (windows.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
            {
                windows.close();
            }
            if(event.type == sf::Event::KeyPressed)
            {
            if(event.key.code == sf::Keyboard::Escape)
            {
             
                 windows.close();
            }
            }
            if(event.type == sf::Event::MouseMoved)
            {


            }
           
        }
     
       
       
       

         buildMenu(fonts,windows);

Graphics / Bundling multiple drawable objects into a returnable object
« on: March 31, 2018, 09:46:59 pm »
I am interested in creating a separate function to draw my menu screen in a game I'm making, how would I accomplish this in sfml and what would i need the function to return?

Graphics / Window opens then closes really fast
« on: March 23, 2018, 03:00:02 am »
I'm building a game in Sfml, and I want to print text to the display screen easier so I created a function that does it for me, but, whenever I run the function, the window opens then closes really fast, not allowing me to see the results. However, when I don't use the function to print text to the console, nothing happens, I was wondering what would help me resolve this problem

This really should be in the window section, but I can't move the question.

Here is my Code

Main.cpp
#include <SFML/Graphics.hpp>
#include <iostream>
#include "write.h"
#include <SFML/Graphics/Font.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode::getDesktopMode(), "SFML works!");
    sf::Font fonts;
if(!fonts.loadFromFile("bit.ttf"))
{

std::cerr << "Error loading font" << std::endl;
return EXIT_SUCCESS;
}
sf::Text word;
word.setFont(fonts);
word.setString("Hello World");
word.setFillColor(sf::Color::Red);
    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(print("aiden"));
        window.display();
    }

    return 0;
}
write.h
#ifndef WRITE_H
#define WRITE_H
#include <SFML/Graphics.hpp>
#include <SFML/Graphics/Font.hpp>

sf::Text print(std::string text);



#endif

write.cpp
#include "write.h"
#include <iostream>
#include <SFML/Graphics.hpp>
#include <SFML/Graphics/Font.hpp>

sf::Text print(std::string text)       // std::string font)
{
sf::Font fonts;
if(!fonts.loadFromFile("bit.ttf"))
{

std::cerr << "Error loading font" << std::endl;
}
sf::Text word;
word.setFont(fonts);
word.setString(text);
word.setFillColor(sf::Color::White);
return word;
}

Graphics / Font library not being linked to mingw

Problem
Error undefined reference to `_imp___ZN2sf4Font12loadFromFileERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE'
Can't figure out the problem because the .ttf file is in the folder that the program i'm compiling is in.

Command I used
g++ main.cpp -IC:\Development\SFML-2.3.1\include -LC:\Development\SFML-2.3.1\lib -lsfml-graphics -lsfml-window -lsfml-system -o a.exe

Code
#include <SFML/Graphics.hpp>
#include <iostream>
//#include "intro.h"

int main()
{
   sf::RenderWindow Window(sf::VideoMode::getDesktopMode(),"Hello Window");
   
   sf::Font font;
   if(!font.loadFromFile("bit.ttf"))
   {
       std::cout << "No Work";
   }
   
   sf::Text text("hello", font);
   text.setCharacterSize(30);
   text.setStyle(sf::Text::Bold);
   text.setColor(sf::Color::Red);
   
    while(Window.isOpen())
    {
     
      sf::Event Event;
      while(Window.pollEvent(Event))
      {

          if(Event.type == sf::Event::Closed)
          {

              Window.close();
          }

      }

      // Declare and load a font


// Create a text

// Draw it
      Window.draw(text);
      Window.clear(sf::Color());
      Window.display();
    }
}
