Thank you for your answer exploit3r,

If reading the faq answered my questions i wouldn't have posted here.

I tried a nighly build of sfgui and it didn't work for sfml 2.2.

I don't have an ext lib folder, i tried redoing the codeblocks step but no option work now.

I'll go ask on the sfgui forum

General / Need help compiling/building [UNSOLVED]

« on: February 25, 2015, 07:11:27 pm »

Hi,i would like to use sfml with sfgui.
If i understand correctly the last version of sfgui require me to build sfml from the git files first.

I manage to compile SFML-master with cmake gui with no errors.
I built the sfml project file with codeblocks and i chose install .

I dl glew-1.12.0-win32 and SFGUI-0.2.3-source.

I get this when i clic configure:



I indicate the glew include and glew library and i clic configure again and i get this:



I indicate the sfml folder that codeblocks created and i get this:



I am not very familiar with cmake so i don't know what to do now.

Should i rebuild sfml ? Is there any precompiled sfgui libs that can work with sfml 2.2 or sfml git ?

Please help the debutant that i am.

Graphics / Re: collisions with mouse

I think i found what you need :

http://www.sfml-dev.org/tutorials/2.2/graphics-transform.php

In the bouding box section there is this :

// get the bounding box of the entity
sf::FloatRect boundingBox = entity.getGlobalBounds();

// check collision with a point
sf::Vector2f point = ...;
if (boundingBox.contains(point))
{
    // collision!
}

Make the "point" contain your mouse coordinates and i will work ( i think )

Thank you Laurent !

I don't even remember why i did it this way 

while (window.pollEvent(event))
            {
                switch (event.type)
                {
                    case sf::Event::Closed:
                        window.close();
                        break;

                    case sf::Event::KeyPressed:
                        {
                            if (event.key.code == sf::Keyboard::S)
                                {
                                    view.move(0, -32);
                                }
                            else if (event.key.code == sf::Keyboard::X)
                                {
                                    view.move(0, 32);
                                }
                            else if (event.key.code == sf::Keyboard::W)
                                {
                                    view.move(-32, 0);
                                }
                            else if (event.key.code == sf::Keyboard::C)
                                {
                                    view.move(32, 0);
                                }

Thank you for your fast answer, i forgot to post the "event" lines :

I have this:

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

                if (sf::Keyboard::isKeyPressed(sf::Keyboard::S))
                {
                    view.move(0, -32);
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::X))
                {
                    view.move(0, 32);
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::W))
                {
                    view.move(-32, 0);
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::C))
                {
                    view.move(32, 0);
                    title += " XX";
                    window.setTitle(title);
                }
 

I added this:

title += " XX";
window.setTitle(title);

And it briefly show four X each time the camera moves.

Should i post my entire (not so long) code ?

Graphics / Little questions/issue about view.move [SOLVED]

« on: February 24, 2015, 03:33:29 pm »

Hi,i'm learning both c++ and sfml and i did a simple camera movement with 4 keyboard keys.

sf::View view(sf::FloatRect(0, 0, 640, 360));

window.setView(view);

                if (sf::Keyboard::isKeyPressed(sf::Keyboard::S))//move the camera up
                {
                    view.move(0, -32);
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::X))//move the camera down
                {
                    view.move(0, 32);
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::W))//move the camera left
                {
                    view.move(-32, 0);
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::C))//move the camera right
                {
                    view.move(32, 0);
                }
 

My problem is that the camera move double the distance.

example : view.move(32, 0) will make the view/camera move 64 pixels to the right and not 32.

Is that normal ?
Why ?

Thank you very much Gan for your fast answer 

I am beginner in both c++ and sfml and i had no idea this was possible, guess i have a lot more to learn

I am testing each thing i will need for a game and for now i can check the position of my cursor directly.



How do i mark this thread as SOLVED ?

Hi, currently i display the position of a sprite in the titlebar for monitoring purposewith this code:

sf::Vector2f positioncurseur = curseur.getPosition();

std::string cursx = std::to_string ( positioncurseur.x );
std::string cursy = std::to_string ( positioncurseur.y );

title += cursx;
title += " ";
title += cursy;

It works well and give me this :



It annoy me since it is for a t-rpg with a grid so no decimals are needed.

Is it possible to remove the zeroes and the dot without too many lines of code ?

That solved it.

I feel dumb, i need to continue to learn c++

code with comments :

    sf::Vector2i position = sf::Mouse::getPosition(window); // get the position of the cursor inside the window

        string title ( "SFML ");//create a string with "sfml" writtent in it

        std::string posx = std::to_string ( position.x );//convert the x coordinate from int to string
        std::string posy = std::to_string ( position.y );//convert the y coordinate from int to string

        title += posx;//add the x coordinate after "sfml" in the title string
        title += " ";//add a space in the title string
        title += posy;//add the y coordinate after the space in the title string

        window.setTitle(title);//set the title of the window to what is written in the title string

Thank you very much Laurent for your answer and for your work SFML is awesome !

Thank you for your very usefull answers Strelok and Nexus,

i have done this

sf::Vector2i position = sf::Mouse::getPosition(window);

    string title ( "SFML ");

    std::string posx = std::to_string ( position.x );
    std::string posy = std::to_string ( position.y );

    title += posx;
    title += posy;

    sf::Window::setTitle(title);

but i get this error (i'm using codeblocks):

error: cannot call member function 'void sf::Window::setTitle(const sf::String&)' without object

I don't know what to do to fix it .

Window / Cursor position in title bar

« on: October 08, 2014, 06:42:52 pm »

Hi everyone, i'm new at using c++ and sfml.

I need to display the cursor position in the title bar next to the title.

I tried this :

sf::Vector2i position = sf::Mouse::getPosition(window);

    sf::String title ;

    title += position.x;
    title += position.y;

    sf::Window::setTitle(title);

My problem is that position.x and position.y give a int and i need to put them in a sf::String.

Can someone help me fix this.

Do you know another way to do it ?
