Hi guys
sorry for my english, because I'm italian.
I've a problem with the input from keyboard, I set that when S is pressed to
write in the console a string, but when I press it, it compares a lot of times, How can I solve this type of issue? Thank you!

well it is creating a positive result since you are holding it down. I'm guessing what you want is a single pulse?

I do not have access to my code atm but what you need is just another kind of input manager that re-dispatches events but uses bool locks to see if that event was already continuously sent. it locks up once it is sent and only unlocks when the event is not being received.

modified from tutorial 4: movement

Code: Select all

class MyEventReceiver : public IEventReceiver
{
public:
        // This is the one method that we have to implement
        virtual bool OnEvent(const SEvent& event)
        {
					
	if (event.EventType == irr::EET_KEY_INPUT_EVENT)
	{
						
						// There is one known bug. It will work but when you press
						// first the else{...} is executed and then the next time passing
						// this if statement the {...}else us run
						if( KeyIsDown[ KEY_KEY_S ] )
						{
							
							// print the str
							KeyIsDown[ KEY_KEY_S ] = false;

						} else
						{
							
							KeyIsDown[event.KeyInput.Key] = event.KeyInput.PressedDown;
								
						};

					};

          return false;
					
				}

        MyEventReceiver()
        {
                for (u32 i=0; i<KEY_KEY_CODES_COUNT; ++i)
                        KeyIsDown[i] = false;
        }

private:
        bool KeyIsDown[KEY_KEY_CODES_COUNT];
};

something like this should work

EDIT: previous message wich I did post half deleted. Really somethimes I am in need of an update myself.

You could also use two arrays for last and current key state and compare those two.
So if last time the key was up and now its pressed, you can get that single press.
