What you will need:
- ASCII Conventer online
Dont like standard html textbox? Let's make your own! Everything is much simpler than it seems.
For this example you will need only 2 objects. Keyboard and text object. Name it "source".
Now open Event sheet. Our first event will be:
On any key pressed -> source: append Keyboard.StringFromKeyCode(Keyboard.LastKeyCode)
Keyboard.StringFromKeyCode(Keyboard.LastKeyCode) - this may look scary.
Let's analyze in detail:
Keyboard.LastKeyCode - will return character ASCII code
if you press on your keyboard...
A it will return 65
B will return 66
! will return 33
Keyboard.StringFromKeyCode - will return string describing the character of the specified ASCII code
Keyboard.StringFromKeyCode(65) = A
Keyboard.StringFromKeyCode(33) = !
Keyboard.StringFromKeyCode(37) = %
So we combined these two expressions and that's what we got:
It shows every button which we press. Now we need to separate symbols that we need.
All English characters (in upper case) have ASCII codes from 65 to 90.
Now by using "System -> Compare two values" we can add two conditions.
Now it displays only letters.
