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
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
