Window / [Linux]window.setPosition()

« on: February 04, 2015, 08:27:34 pm »

I think this is a bug on linux: not setting correctly the position of the window. (last git sources - Linux Mint 17.1)

(click to show/hide)

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

int main()
{
        sf::RenderWindow window(sf::VideoMode(800, 600), "CustomBorders", sf::Style::None);
        sf::RectangleShape bar(sf::Vector2f(800,20));

        sf::Vector2i m_moveOldPos = {0, 0};

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

        if (sf::Mouse::isButtonPressed(sf::Mouse::Left) && bar.getGlobalBounds().contains(static_cast<sf::Vector2f>(sf::Mouse::getPosition(window))))
        {
                if (m_moveOldPos != sf::Vector2i(0, 0))
                {
                        sf::Vector2i newPos(window.getPosition() + sf::Mouse::getPosition(window) - m_moveOldPos);

                        window.setPosition(newPos);
                        std::cout << newPos.x << ", " << newPos.y << " | " << window.getPosition().x << ", " << window.getPosition().y << "\n";
                }
                m_moveOldPos = sf::Mouse::getPosition(window);
        }
        else m_moveOldPos = {0, 0};

        window.clear();
        window.draw(bar);

« on: January 05, 2013, 01:50:21 pm »

Hello! I decided to make an blog and to post tutorials about SFML and informations about my projects. Here is my blog: http://alexanderx.net/
I will try to upload at least 1 tutorial per week.

Here is a list of actual tutorials on my blog:

• Custom mouse cursor
• Create a simple piano
• How to apply collision?
• Jumping in 2D platform games
• How to flip sprites
• How to create a simple button
• How to create a screenshot system

Another problem. I try to make a moving system but I have a probem: when the rectangle(player) fall down from the floor( big regtangle) and I move to right || left the player go in the floor and I don't know how to ressolve it.

Graphics / Texture to a rectangle

« on: October 07, 2012, 12:25:27 pm »

I have soprems setting to a  renctangle the texture:

     sf::Texture texture;
        if (!texture.loadFromFile("resources/backgroundimage.png"))
     return -1;

    // Jucatorul din stanga
    sf::RectangleShape leftPaddle;
    leftPaddle.setSize(paddleSize - sf::Vector2f(3, 3));
    leftPaddle.setOutlineThickness(3);
    leftPaddle.setTexture(texture);
    leftPaddle.setOrigin(paddleSize / 2.f);

And give me these erors:

General / Can't figure out - SFML 2.0 - MinGW( Code::Blocks)

« on: October 06, 2012, 07:57:09 am »

Hello guys. For some hours I try to set SFML 2.0 for Code::Blocks( MinGW) and can't. Here is what I tried:
1.I used the files from download directly and setted the Code::Blocks fom tutorial and used the example from tutorial to test if work.
Erros:

ld.exe||cannot find -lsfml-graphics|
||=== Build finished: 1 errors, 0 warnings ===|

2.Tried with the tutorial to recompile it using CMake. I recompiled without errors and setted in the Code::Blocks the new dir. Same example used.
Errors:

D:\C++ Work\Test\Untitled3.cpp|1|error: SFML/Graphics.hpp: No such file or directory|
D:\C++ Work\Test\Untitled3.cpp||In function 'int main()':|
D:\C++ Work\Test\Untitled3.cpp|5|error: 'sf' has not been declared|
D:\C++ Work\Test\Untitled3.cpp|5|error: expected ';' before 'window'|

D:\C++ Work\Test\Untitled3.cpp|6|error: expected ';' before 'shape'|
D:\C++ Work\Test\Untitled3.cpp|7|error: 'shape' was not declared in this scope|

D:\C++ Work\Test\Untitled3.cpp|12|error: 'event' was not declared in this scope|
D:\C++ Work\Test\Untitled3.cpp|14|error: 'sf' has not been declared|
||=== Build finished: 12 errors, 0 warnings ===|

3.And in a final I copied the include folder in the recompiled folder and give me the same errors as in point 1.

I using this file for SFML 2.0 LaurentGomila-SFML-2.0-rc-94-g26fa99f.tar ( posted if in case someone want the version)

Please if can someone help me or to figure out using TeamViewer.

P.S.: Sorry for my bad english.
