Really Usefull Header I made (Window's Key/Mouse Inputs)

Hello, Ive been working on a header class that makes using keyboard and mouse inputs easy. (WORKS ONLY ON WINDOWS, SORRY ;) )

Code: Select all

#include <Windows.h>
#pragma once

namespace Input
{

	namespace Key
	{

		{
			keybd_event(VK_SHIFT,0,0,0);

I didn't get every single key input due to lazyness :lol:

Here' some tutorials on how to use this sucker :

If you want to make your program to press the "a" key, you would type:

Input::Key::A();


if you want the program to do something if the "a" key was hit you would do this:

if(Input::KeyIsDown::A())
{
//DO SHIT
}

Same works for the mouse. Hope you find this use full.



*IMPORTANT*

You are free to use the header in your program, that's why I made it. Also you can add on to it which is why i pasted the whole source, (possibly gut the rest of the keys in there :lol: ) but please don't take full credit, i hate when people take all the credit of someone elses work...


Hope this comes in handy to some people :mrgreen:

Hmmm... there's definitely a lot of pattern, here. I'm sure it can be reduced somehow...

How? Because it would be nice if it was reduced :S

Well, you do the same two function calls every time except for a parameter. So how about we pass that parameter into a general function? Let's see. The numbers you're passing are simply the character value. So how about

input.h

Code: Select all

#ifndef INPUT_H
#define INPUT_H
class Input {
public:
	void simulateKeypress(int key, bool release = true);
	bool keyIsDown(int key);
};
#endif
input.cpp

Code: Select all

#include <ctype> //for toupper
#include <windows.h>

using namespace std;

//pass any character or VK_ constant to this to simulate the keypress.
//used int because VK_ constants probably aren't valid characters
void Input::simulateKey(int key, bool release) {
	key = toupper(key);
	keybd_event(key,0,0,0);
	if (release)
		keybd_event(key, 0, KEYEVENTF_KEYUP, 0);
}

bool Input::keyIsDown(int key) {
	return GetAsyncKeyState(key);
}
That's keyboard. You can either do something similar for the mouse, or add an enumerator and a switch statement, or leave them as-is.

Looks pretty cool... Am I right in thinking you need a kind of 'game loop', or for instance if I put this with no loop or anything..

Code: Select all

if(Input::KeyIsDown::A())
{
//DO SHIT
}
Will it wait till the A key is pressed before proceeding?

Sorry if this is a dumb question :oops:

No because it's an if statement, so it would see if A is hit do stuff, if not just skip it...

It looks like the code simulates a key press, but I'm not really sure, since I'm not familiar with what keybd_event does. Hence the name of my function *shrug*

This would need a loop unless you're really damn fast with hitting a key before the program ends :lol:

But here's a better example of how to use this with the good ol' hello world program :mrgreen:

Code: Select all

#include <iostream>
#include <Inputs.hpp>

int main()
{
	bool Run = true;

	while(Run)
	{
		if(Input::KeyIsDown::A())
		{
			std::cout<<"Hello world\n";
		}
	}
}
Is that easier to understand? Sorry for not showing a better example before D:


Also for MarauderIIC :

What keybd_event does it it pretty much simulates a key press. So instead of using my header and type Input::Key::A(); you could do

Code: Select all

keybd_event((0x41),0,0,0);
What that would do is press the A key, but I have this in my header:

Code: Select all

keybd_event((0x41),0,KEYEVENTF_KEYUP,0);
So that it will release the key, that way its not held down. As for the key checking, I use this to check if the A key is pressed:

Code: Select all

		bool A()
		{
			if(GetAsyncKeyState((0x41)))
			return true;
			else
			return false;
		}
I'm not %100 sure if this is exactly what it means, but this is what I think. GetAsyncKeyState checks if a key is pressed. So basicly in that code its saying if A is pressed return true. The 0x41 is the virtual key code. Theres a whole list of all the key codes on this link: http://msdn.microsoft.com/en-us/library/ms645540.aspx

This is just a simple hex version of an ASCII character value, so instead of making lots of seperate functions for each key, you could have 1 function where you pass the ASCII value like...

KeyIsDown(int value){
keybd_event((value),0,0,0);
keybd_event((value),0,KEYEVENTF_KEYUP,0);
}

and then use it like so

if(KeyIsDown('a')){
cout << "a is hit";
}

You'll see that that's what my version does, Ryan.
