ok, first off, the only bit of info you gave for us to work with is that you want to move a character with the keyboard, and you're using VC++............

now, we need to know a few other things before we can fully answer your question:

what do you want to move it in? a console? openGL? directx? win32?
what type of character? a character sprite? a character letter ('a')?


basically, however, the basic way it works for moving characters on a screen:

in pseudocode

Code:

---

is left key pressed
    move character left
is right key pressed
    move character right
....etc.......

Sorry for not explaning well.
I want to start moving a character like 'a' in a console.

Check out the console tutorials at Game Tutorials

I have been there. Do you have any idea how to move an object whit a constant velocity??
So when i hold a key, the object don't stop a while and continue whit a higher velocity. You could se this problem if you open notepad and hold a key like 'a' you will notice that it stops a while and then it continues whit a higher velocity.

And other problem that i cannot solve is how to make an object move holding a key and at the same time pressing an other key whitout stoping the object. I will be very grateful if you could show me some examples so i can understand better.

I don't know about pressing the other key thing, but if you want other things in your game to continue going on even if the user is pressing a key, use the function "kbhit()". An example:

Code:

---

for(;;)
{
    if(kbhit())
    {
          char key = getch();
          if(key == 'w') // Move forward
          {
                // Movement code here
          }
    }
    // Do something else if a key isn't it
    DoSomething();
}

---

ok, check out GetAsyncKeyState(a) & 0x81 where a is a value (for example: a='A'). this tests the state of 'A' and if it is, returns true

example:

Code:

---

if(GetAsyncKeyState(VK_UP) & 0x81)  // VK_UP is a "virtual key" for the up arrow key, right click it and say "go to definition" if you want to see more about other virtual keys
      MoveCharacter(0,-1);
if(GetAsyncKeyState(VK_DOWN) & 0x81)
      MoveCharacter(0,1);

.....etc........with the other keys...........where MoveCharacter would move the character based on (x,y)

---

hopefully that won't confuse you too much ;) you might need windows.h to use that function. and if the above doesn't work they way you want, try them out these ways:

GetAsyncKeyState(VK_UP) & 0x80
GetAsyncKeyState(VK_UP) & 0x01

each one testing different bits......i'm not exactly sure which one does it the way you want to, so just test 'em all :)
