Input problem?

[Mr_Gnome]

I'm having sort of a problem with how I'm handling my mouse click events. I'm using input and I have it so that when I click the window it will call a function, but it will call said function several time when I just clicked once.

With this code here:

Code: [Select]

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

void Hello() {
std::cout << "hello" << "\n";
}

int main()
{
    sf::Window App(sf::VideoMode(800, 600, 32), "Input?");

    const sf::Input& Input = App.GetInput();

    while (App.IsOpened())
    {
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            if (Event.Type == sf::Event::Closed)
                App.Close();

            if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
                App.Close();
        }
        bool LeftButtonDown = Input.IsMouseButtonDown(sf::Mouse::Left);
        if(LeftButtonDown) Hello();

        App.Display();
    }

    return EXIT_SUCCESS;
}

I get:

hello
hello
hello
hello
hello
hello
hello
hello
hello
[...]*

*you get the point.

Is it that I'm handing my mouse clicks wrong or what?

Input.IsMouseButtonDown returns true continuously as long as the mouse button is pressed, so yes it is perfectly normal that your function gets called many times.

If you want to be notified once, when the click happens, use events instead (see sf::Event::MouseButtonPressed).

Ok, thanks... I got what I wanted to work

Strangely I am getting the same problem and I am using Event.

EDIT: Sorry, my bad. Problem solved!
