Detecting pressed keys

[crisro996]

Hi, I'm working on a small labyrinth game (you got a hero, you move around and kill monsters) and I was wondering if there is a way besides Win API(the only thing I found on the internet) to detect the keys that are pressed.

I ask this because when I want to move my hero I have to tell it where to go (W,A,S,D) and then press enter. Is there something that will automatically do this? If not, do you happen to know the simplest way to do something similar or include the respective piece of code in my project?

I'm running windows in case you ask and didn't realize :D

Thanks in advance,
Chris

You could use the _getch() function in the conio.h header file. It works with MSVC++, but I'm not sure with other IDEs. If compatibility is very important to you, you may want to find another way.

Here's an example:

#include <iostream>
#include <conio.h>

int main()
{
	char ch; //or 'int ch;' (it doesn't really matter)

	//the program pauses here until a key is pressed
	ch = _getch();

	if(ch == 'a')
		std::cout << "You pressed a!" << std::endl;
	else
		std::cout << "You did not press a!" << std::endl;

	return 0;
}

Thanks a lot! It worked great :D

If you want to do it with out pressing enter, you could use GetAsyncKeyState() might be lowercase s.

if (GetAsyncKeyState(0x43))
{
        Code here
}

That should be for a. It is in hexidecimal.
