Quick help afk bot coding

Could someone give me a brief tutorial or show me one explaining how to create a afk bot through this code? using c + +? Thank you.

Code:
while( TRUE )
{
if( GetTickCount() >= ( pow( 6000, 2 ) ) )
{
Sleep( 10 );
mouse_event( MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0 );
mouse_event( MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 );
}
else
{
return;
}
}

mouse_event , will not work
it's patched i think !!
