Hi, so I made a std::unordered_map to contain my user input key bindings. I have a struct called "Bindings" that contains the following members.
Code: [Select]
struct Binding
{
Binding() {}

Binding(InputType inputTypes, sf::Event::EventType eventType1, sf::Event::EventType eventType2,
    sf::Keyboard::Key keyCode1, sf::Keyboard::Key keyCode2,
sf::Mouse::Button mouseCode1, sf::Mouse::Button mouseCode2)
            : my_InputTypes{ inputTypes }, m_enumEventType1 {eventType1}, m_enumEventType2 { eventType2 },
        m_keyCode1{ keyCode1 }, m_keyCode2{ keyCode2 }, m_mouseCode1{ mouseCode1 },
    m_mouseCode2{ mouseCode2 }{}

InputType my_InputTypes;
sf::Event::EventType m_enumEventType1;
sf::Event::EventType m_enumEventType2;
sf::Keyboard::Key m_keyCode1;
sf::Keyboard::Key m_keyCode2;
sf::Mouse::Button m_mouseCode1;
sf::Mouse::Button m_mouseCode2;


};

using BindingMap = std::unordered_map<std::string, Binding >;

I read a .csv file to enter my bindings.
Code: [Select]
void EventManager::LoadBindings()
{
std::ifstream keyBindings("Keys.csv");

if (!keyBindings.is_open()) { std::cout << "Error loading Keys.csv..."; }

int number_of_lines = 0;
std::string lineCount;

while (std::getline(keyBindings, lineCount))
++number_of_lines;
std::cout << "Number of lines in .csv file: " << number_of_lines << '\n';

keyBindings.close();
keyBindings.open("Keys.csv");

std::string mapKey;
std::string myInputType;
std::string eventType1;
std::string eventType2;
std::string keyCode1;
std::string keyCode2;
std::string mouseCode1;
std::string mouseCode2;

for (int i=0; i <= (number_of_lines-1); ++i)
{
std::getline(keyBindings, mapKey,',');
std::getline(keyBindings, myInputType,',');
std::getline(keyBindings, eventType1,',');
std::getline(keyBindings, eventType2, ',');
std::getline(keyBindings, keyCode1,',');
std::getline(keyBindings, keyCode2,',');
std::getline(keyBindings, mouseCode1,',');
std::getline(keyBindings, mouseCode2,'\n');

std::cout << mapKey << "|"
<< stoi(myInputType) << "|"
<< stoi(eventType1) << "|"
<< stoi(eventType2) << "|"
<< stoi(keyCode1) << "|"
<< stoi(keyCode2) << "|"
<< stoi(mouseCode1) << "|"
<< stoi(mouseCode2) << '\n';

m_bindingMap.insert(std::pair <std::string, Binding>
(mapKey, { static_cast<InputType>(stoi(myInputType)),
   static_cast<sf::Event::EventType>(stoi(eventType1)),
static_cast<sf::Event::EventType>(stoi(eventType2)),
       static_cast<sf::Keyboard::Key>(stoi(keyCode1)),
               static_cast<sf::Keyboard::Key>(stoi(keyCode2)),
   static_cast<sf::Mouse::Button>(stoi(mouseCode1)),
   static_cast<sf::Mouse::Button>(stoi(mouseCode2))}));

}
keyBindings.close();
PrintMap();
}

void EventManager::PrintMap()
{
for (auto element : m_bindingMap)
{
std::cout << element.first << " :: " << static_cast<int>(element.second.my_InputTypes)
   << " :: " << static_cast<int>(element.second.m_enumEventType1)
   << " :: " << static_cast<int>(element.second.m_enumEventType1)
                       << " :: " << static_cast<int>(element.second.m_keyCode1)
                       << " :: " << static_cast<int>(element.second.m_keyCode2)
                       << " :: " << static_cast<int>(element.second.m_mouseCode1)
                       << " :: " << static_cast<int>(element.second.m_mouseCode2)
   << std::endl;
}
}
The map works perfectly and is tested... Now, I'm trying to make a multikey bool that flags "true" if 2 or more buttons are pressed at the same time.
Code: [Select]
bool EventManager::TestEvent(Binding binding, sf::Event event)
{
//MultiKeyEvents
if ((binding.my_InputTypes == InputType::MultikeyEvent) &&
(binding.m_enumEventType1 == event.KeyPressed) &&
(binding.m_enumEventType2 == event.MouseButtonPressed) &&
(binding.m_keyCode1 == event.key.code) &&
(binding.m_mouseCode1 == event.mouseButton.button))
{
return (true);
}

return (false);
}

For this example, the keycode = 0 for "A" and the mouse button code = 0 for "Left Mouse Button". I'm trying to register "true" when they are both pressed together. However, with this if statement it will register "true" if I press "A" or the "Left Mouse Button" separately. What am I missing here!? I only want it to be "true" if they are both pressed at the same time.

I believe that the reason that each event has only it's own parameters and don't store any other information. So instead checking value of the event, check state that stored in your map(if there isn't any - add it).
