Text-input, shift modifier.

Posted Saturday, 27 August, 2011 - 18:14 by james_lohr in

I'd like to have text input within my game, and so I'd like to map key presses to their corresponding characters, complete with shift modifiers.

I can do this manually by mapping ranges to keys, e.g. : 

            char keyChar;
            kval = (int)e.Key;
 
            if (kval >= (int)Key.A && kval <= (int)Key.Z)
 
                int val = kval - (int)Key.Number0;
 
 
                if (!shiftDown)
                {
                    val += (int)'a';
                }
                else
                {
                    val += (int)'A';
                }
 
               keyChar = (char)val;
            }

However, it's a bit painful to do this for every key on the keyboard, plus I'm sure it may vary depending on keyboard.

Is there a correct/better way of doing this?

Cheers,

James L.

The KeyPress event does this translation for you.

So it does! Thank you, that was easy. :)

I hadn't spotted it because I was expecting it to be in OpenTK.Input, but I appreciate that it depends on the native window and therefore needs to live where it is.
