Simple External Crosshair
Title Says it all, It is a very good example for people who are beginners in C++ and can be used in any game since its external.
I have left Sleep(); as (33) which is most common Frames Per Second in FPS games I think. Make sure to change the RGB to your likings for different colours.

Code:
#include <windows.h>
#include <iostream>
#include <math.h>
using namespace std;
bool crosshairon=false;
HDC ragedc = NULL;
int crosshairsize=0;
int cx=0;
int cy=0;
void CrossThread(void)
{
while(1)
{
if(GetAsyncKeyState(VK_NUMPAD0)&1)
{
crosshairon=!crosshairon;
ragedc = GetDC(HWND_DESKTOP);
cx=GetSystemMetrics(SM_CXSCREEN)/2-((crosshairsize-1)/2);
cy=GetSystemMetrics(SM_CYSCREEN)/2-((crosshairsize-1)/2);
}
Sleep(1);
}
}
int main()
{
cout<<"Crosshair size in pixels:\n";
cin>>crosshairsize;
if(crosshairsize%2==0)
{
crosshairsize+=1;
}
system("cls");
cout<<"Press numpad0 to toggle the crosshair on and off\n";
CreateThread(0,0,(LPTHREAD_START_ROUTINE)CrossThread,0,0,0);
while(1)
{
if(crosshairon==true)
{
for(int i=0;i<crosshairsize;i++)
{
SetPixel(ragedc, cx+i, cy+((crosshairsize-1)/2), RGB(255,0,0));
SetPixel(ragedc, cx+((crosshairsize-1)/2), cy+i, RGB(0,0,255));
}
if(crosshairon==false)
for(int i=1;i<crosshairsize;i++)
{
SetPixel(ragedc, cx+i, cy+((crosshairsize-1)/2), RGB(0,0,0));
SetPixel(ragedc, cx+((crosshairsize-1)/2), cy+i, RGB(0,0,0));
}
}
Sleep(33);
}
}Thanks and +Rep If you like it. Also added the .exe file
