how do i get Turing to not detect held keys
For example:

code:


var key : array char of boolean
var pressed1, pressed2 : boolean

loop

Input.KeyDown (key)

% draw 3 boxes
drawfillbox (100, 100, 110, 110, blue)
drawfillbox (110, 100, 120, 110, red)
drawfillbox (120, 100, 130, 110, blue)

% wipe out boxes as left arrow is pressed
if key (KEY_LEFT_ARROW)  and pressed1 = false then
drawfillbox (100, 100, 110, 110, white)
pressed1 := true
elsif key (KEY_LEFT_ARROW) and pressed1 = true and pressed2= false then
drawfillbox (110, 100, 120, 110, white)
pressed2 := true
end if
end loop


holding down left will make both boxes disappear

how do i change it so tht they will disappear at each press?

The loop passes far too quickly to make a difference to a human viewer. Try putting a delay if a button is pressed.

Its still not the error, the error is that you should set it to false when the key isn't pressed

oops its supposed to be set to false, ignore that

what im trying to get to is how do i enter code so that the two boxes will be wiped after the left arrow key is pressed twice

right now, holding down the left arrow will wipe out both (btw i dont know why i drew 3 boxes, ignore that too)

There is an error in your code in which you don't give the variables an initial value but after fixing it.

Although I still don't see the boxes getting wiped out after setting them both to false

I think this is what you mean....if not, my bad Very Happy


code:

var pressed : int := 1
var k : string (1)


% draw 3 boxes
drawfillbox (100, 100, 110, 110, blue)
drawfillbox (110, 100, 120, 110, red)
drawfillbox (120, 100, 130, 110, blue)

loop
    if hasch then
        getch (k)
        % wipe out boxes as left arrow is pressed
        if k = KEY_LEFT_ARROW and pressed = 1 then
            drawfillbox (100, 100, 110, 110, white)
            pressed := pressed + 1
        elsif k = KEY_LEFT_ARROW and pressed = 2 then
            drawfillbox (110, 100, 120, 110, white)
            pressed := pressed - 1
        end if
        delay (1)
    end if
end loop
