Input.KeyDown

[JSBN]

For Input.KeyDown, how do i detect an uppercase letter (ie. A)
i know to detect shift it is (KEY_SHIFT) and for a it is ('a').
Itried puting the 2 togeather, that d'dn't work, and i tried ('A'), but that didn't work either.
:/

you check for both at same time.

if chars(Key_SHIFT) and chars('a') then
...

[JSBN]

i already tried that :/

tony is right.... if you go to the help file, then...

Quote:

The array returned is a list of all the characters. A key is currently pressed if the array element with the corresponding character is true. For example, the a key is pressed is chars ('a') is true. Note that each key is individually represented, so if the user has pressed Shift+a to get a 'A', then Input.KeyDown would register Shift and 'a' as pressed, but not 'A'.

and this works for me

code:

var chars : array char of boolean loop     Input.KeyDown (chars)     if chars ('a') & chars (KEY_SHIFT) then         put "hi"     else         put "bye"     end if     locate (1, 1) end loop

ok, i figured out my problem, i had it set up wrong.
i had:

code:

if chars ('a') then ... elsif chars ('a') and chars (KEY_SHIFT) then ...

what u need is :

code:

if chars ('a') and chars (KEY_SHIFT) then ... elsif chars ('a') then ...

THe upper case letter MUST go b4 the lowercase letter
THx for your help, and esspecially to blade for makingme relize this.

another question, I was wondering what Caps lock was.

[Homer_simpson]

i dont think that input keydown supports capslock =/

[Asok]

if ANYONE knows how to detect caps lock via Input.Keydown they'll get 25 bits. (must provide source code)

[Homer_simpson]

lol if anyone finds out how to do that using turing... he'll get 100 bits...(knowing that it's impossible...)

[Andy]

ya it is impossible... can you even detect if shift is pressed?

[Catalyst]

u people...

code:

var chars : array char of boolean var key : string (1) := "!" fcn capTest (k : string (1)) : boolean     if ord (k) >= 65 and ord (k) <= 90 then         result true     else         result false     end if end capTest loop     getch (key)     Input.KeyDown (chars)     if chars (KEY_SHIFT) = false and capTest (key) then         put "Caps Lock is on"     elsif chars (KEY_SHIFT) = true and capTest (key)=false then         put "Caps Lock is on"            else         put "Caps Lock is off"     end if end loop

[Andy]

catalyst that only checks for letters and we want to know if caplocks is pressed without inputing data.

[JSBN]

can u get so that there is no getch?

[Catalyst]

i dont think i can do i withour getch since the only reason it works is that getch() picks up on the caps lock

[Asok]

JSBN, that should work with what we're doing anyways because var key wont be drawn it just holds the status of caps lock.
