Graphics / Are there any function that could change the coordinates system of window ?

Oh .. uhm ...
I want to change the coordinates system of window from the top-left to the bottom-left to easy to draw my sprites.

Tks, after clearing code and test each line, I saw that the text had been draw, but square.setFillColor(...) -> so, it will draw over it and swap those lines, it work perfectly ^^ ... thanks for reply

I don't know 
I just want to add my text, my square to rendertexture to draw once. ( example if there weren't error, I could draw 1 rect that had both text in the middle and border around )

In fact, it is black screen, I don't know how to solve ... I think it would be the same, I captured my screen, it would be shown like the top but it actually shown like the bottom

EDIT: Sr about my english >.<

Hi there, I have almost the same problem with @traxys, so I don't create new topic, hope anybody help me to solve it
This is my code:

#include <SFML/Graphics.hpp>
#include <sstream>
#include <iostream>

#define WND_WIDTH 400 // Window Width
#define WND_HEIGHT 400 // Window Height
#define S_WIDTH 100  // Square Width
#define S_HEIGHT 100 // Square Height
#define SPEED 10

int main(void)
{
    sf::RenderTexture rtexture;
    rtexture.create(S_WIDTH,S_HEIGHT);
    rtexture.setSmooth(true);

    sf::Font font;
    if(!font.loadFromFile("arial.ttf")) std::cout << "Error ! Can't load font file [arial.ttf]";

    sf::Text text;
    text.setFont(font);
    text.setColor(sf::Color::Red);
    text.setString("1234");
    text.setCharacterSize(30);
    text.setOrigin((text.getLocalBounds().width+text.getLocalBounds().left)/2,(text.getLocalBounds().height+text.getLocalBounds().top)/2);
    text.setPosition(S_WIDTH/2.0,S_HEIGHT/2.0);

    sf::RectangleShape square;
    square.setOrigin(S_WIDTH/2,S_HEIGHT/2);
    square.setOutlineThickness(2);
    square.setPosition(S_WIDTH/2,S_HEIGHT/2);
    square.setSize(sf::Vector2f(S_WIDTH,S_HEIGHT));
    square.setFillColor(sf::Color::Black);

    sf::RenderWindow window(sf::VideoMode(WND_WIDTH,WND_HEIGHT),"Testing");
    window.setFramerateLimit(60);
// this is the problem
    sf::RectangleShape rect;
    rect.setTexture(&rtexture.getTexture(),true);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed) window.close();
        }

        window.clear(sf::Color::Black);
        //window.draw(rect);
        window.draw(square);
        window.draw(text);
        window.display();
    }
}
 

Humm... I've created my texture had square and text in the middle of it by using rendertexture. But I can't getTexture() to use even though I can draw on main window ( like the code above ). When comment

window.draw(square);
window.draw(text);
 

and uncomment window.draw(rect), nothing on the screen, why ?

Graphics / How to check whether rectangle intersect with Line ?

« on: May 18, 2014, 12:17:51 pm »

Ok I have this code:

#include <iostream>
#include <SFML/Graphics.hpp>

int main(void)
{
//    sf::RenderWindow window(sf::VideoMode(800,600),"Testing");
//    window.setFramerateLimit(60);

    sf::VertexArray line(sf::Lines,2);
    line[0].position = sf::Vector2f(200,300);
    line[1].position = sf::Vector2f(600,300);

    sf::Rect<float> rect2(line.getBounds());
    sf::Rect<float> rect(200,100,300,200);

    sf::VertexArray drawrect(sf::Quads,4);
    drawrect[0].position = sf::Vector2f(100,200);
    drawrect[1].position = sf::Vector2f(400,200);
    drawrect[2].position = sf::Vector2f(400,400);
    drawrect[3].position = sf::Vector2f(100,400);

//    while (window.isOpen())
//    {
//        window.clear(sf::Color::Black);
//        window.draw(line);
//        window.draw(drawrect);
//        window.display();
//    }
    std::cout << rect.intersects(rect2);
}
 

You can uncomment to see what I have createn.
When I run this code, it always show 0 which mean there aren't intersection. But I think it should be 1, why not ?
If I were wrong, how to correct it ? I mean .. [ the title ]

Graphics / Re: Problem about sf::Text and sf::Sprite/Circle...

« on: May 15, 2014, 04:48:11 pm »

Sorry about my code because I don't know how to setting up 
One more about sf::CircleShape is the top and left attributes of circle.getGlobalBounds().(top/left):
When I set my circle at position (0,0), those attributes aren't equal zero. If so, how to know the circle do touch to the left/right/top/bottom edge of console window or not?
p/s: Below is the screen captured show that top and left value when I run

Graphics / Problem about sf::Text and sf::Sprite/Circle...

« on: May 15, 2014, 04:22:16 pm »

I'm new here, I've learned SFML for 3 days, and got a problem @@.
I really don't know how to set position of sf::Text to the center of sf::CircleShape, have a look at the code below:

#include <SFML/Graphics.hpp>
#include <iostream>

int main(void)
{
    sf::RenderWindow window(sf::VideoMode(800,600),"Object");
    window.setFramerateLimit(60);

    sf::Font font;
    if (!font.loadFromFile("arial.ttf")) std::cout << "Couldn't load font file!" << std::endl;

    sf::Text text;
    text.setFont(font);
    text.setPosition(10,10);
    text.setColor(sf::Color::Red);
    text.setString("A");
    text.setCharacterSize(100);

    sf::CircleShape circle;
    circle.setFillColor(sf::Color::White);
    circle.setPosition(10,10);
    circle.setRadius(100);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed || sf::Keyboard::isKeyPressed(sf::Keyboard::Escape)) window.close();
        }
        window.clear(sf::Color::Black);
        window.draw(circle);
        window.draw(text);
        window.display();
    }
}
 

Well, the text has only 1 char and has big size ( easy to see ), I've set its position to (10,10) but it doesn't. Seem like (10,about 20 or 30). How to solve this problem ?
