« on: October 16, 2022, 10:45:05 pm »
hi

tested this code to see if my gamepad was detected, but no
ok with steam and dowloaded joystick tester and ok with it.
also ok in windows joystick configuration

thanks

#include <iostream>

#include <SFML/Window/Joystick.hpp>

int main()
{
    unsigned int joystckID{0};
    sf::Joystick myJoystick;
    while(joystckID < 8) {
        if (myJoystick.isConnected(joystckID)) {
            unsigned int buttonCount = myJoystick.getButtonCount(joystckID);
            std::cout << "joystick ID " << joystckID << " conneted with"  << buttonCount << " buttons.\n";
        }
        else { std::cout << "joystick ID " << joystckID << " not conneted\n"; }
        ++joystckID;
    }
    while(1) {
        if (sf::Joystick::isButtonPressed(0, 1)) { std::cout << "button 1 pressed\n"; }
    }
      return 0;
}

Hey
Unlike the keyboard or mouse, the state of joysticks is sometimes not directly available (depending on the OS), therefore an update() function must be called in order to update the current state of joysticks. When you have a window with event handling, this is done automatically, you don't need to call anything. But if you have no window, or if you want to check joysticks state before creating one, you must call sf::Joystick::update explicitly.
Try calling sf::Joystick::update() once before querying the states of your joysticks.

By the way, all sf::Joystick functions are static, you don't have to (and probably shouldn't) instantiate one.

Probably because you're not flushing your output.
End your cout with << std::flush or << std::endl (endl outputs a newline and flushes)
