I'm sorry, but I can't help you. Turing must not be very popular. I didn't know about it until I saw our first thread on it. Speaking of that, anyone with a need for Turing help should consider posting in one of our other Turing threads instead of starting a brand-new one.

Input.KeyDown get keyboard state

Syntax Input.KeyDown (var chars : array char of boolean)

Description The Input.Keydown procedure allows a program to read which keys are currently being pressed. This procedure is different from getch in that it allows a program to detect when a user presses and releases a button. As such, it is not to be used in conjunction with getch.
The procedure can be used in games where an action takes place while a key is depressed.


Example Determine if the T key is pressed. Note that we check for the lower case letter.

var chars : array char of boolean
Input.KeyDown (chars)
if chars ('t') then
put "The T key is pressed"
end if

Details 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'.
A full list of all the possible characters that can be set with Input.KeyDown can be found in the Key Codes appendix.


Details 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'.

Details The number of keys that can be pressed simultaneously is hardware dependent. Most keyboards can detect a minimum of two keys + Shift + Control + Alt. This means that if you are designing a two player game to be played at a single keyboard and you wish to make certain that players cannot “hog the keyboard” by holding down keys, you should not use more than 6 different keys and three of them should be the Shift, Control and Alt keys.

Example The program reads the keyboard and displays a message while the arrow keys are pressed. It can detect up to all four arrow keys pressed at once.

var chars : array char of boolean
loop
Input.KeyDown (chars)
locate (1, 1)
if chars (KEY_UP_ARROW) then
put "Up Arrow Pressed " ..
else
put " " ..
end if
if chars (KEY_RIGHT_ARROW) then
put "Right Arrow Pressed " ..
else
put " " ..
end if
if chars (KEY_LEFT_ARROW) then
put "Left Arrow Pressed " ..
else
put " " ..
end if
if chars (KEY_DOWN_ARROW) then
put "Down Arrow Pressed " ..
else
put " " ..
end if
end loop

Status Exported qualified.
This means that you can only call the function by calling Input.KeyDown, not by calling KeyDown.

yeah we must be featured on some kind of turing site or something. I wish we could help more but I don't know turing, only a bit of C++ and more php. I want to learn assembly one of these days.

that would be hard to learn

ps. i found this site through google

Archived topic from Iceteks, old topic ID:1891, old post ID:15583

good site eh.

Archived topic from Iceteks, old topic ID:1891, old post ID:15584

is ther anyway i can just draw a box, and move it over 10 pixels when i press the arrow keys??? It will take too long doing it all in IF statements.

Haha

That is cool.

Archived topic from Iceteks, old topic ID:1891, old post ID:15586

wow nowonder everyone go's here. Okay you want to know if you can move a box over 10 pixs without a if statement. hm... I am not sure but you may be able to use lable. I think the if stament is the only way.

Archived topic from Iceteks, old topic ID:1891, old post ID:15605

hey syb,
i got my box to move a little but i need help with the syntax,
when i press the right arrow i want it to move over by 10 pxl's so i have it add 10 to x1,y1,x2,y2, but i am unsure how to declare these as the variables

anyone here??

Archived topic from Iceteks, old topic ID:1891, old post ID:15608

Yes, but syb is the only one here who knows turing. I can help with php though...

Archived topic from Iceteks, old topic ID:1891, old post ID:15613

i am to tiered to think... you do know how to use "Input.KeyDown" stament?


Archived topic from Iceteks, old topic ID:1891, old post ID:15616

yeah, heres what i have so far ( i still get errors and don't know what to do)

var chars : array char of boolean
var x1,y1,x2,y2: int
drawfillbox(x1,y1,x2,y2,7)
loop
Input.KeyDown (chars)
if chars (KEY_RIGHT_ARROW) then
cls x1=x1+10 and x2=x2+10 and y1=y1 and y2=y2
elsif chars (KEY_LEFT_ARROW) then
cls x1=x1-10 and x2=x2-10 and y1=y1 and y2=y2
elsif chars (KEY_DOWN_ARROW) then
cls x1=x1 and x2=x2 and y1=y1-10 and y2=y2-10
elsif chars (KEY_UP_ARROW) then
cls x1=x1 and x2=x2 and y1=y1+10 and y2=y2+10
end if
end loop

Archived topic from Iceteks, old topic ID:1891, old post ID:15626

corection this is what i have

var chars : array char of boolean
var x1,y1,x2,y2: int
x1:=50
x2:=60
y1:=50
y2:=60


loop
drawfillbox(x1,y1,x2,y2,7)
Input.KeyDown (chars)
if chars (KEY_RIGHT_ARROW) then
cls
x1:=x1+10
x2:=x2+10
elsif chars (KEY_LEFT_ARROW) then
cls
x1:=x1-10
x2:=x2-10
elsif chars (KEY_DOWN_ARROW) then
cls
y1:=y1-10
y2:=y2-10
elsif chars (KEY_UP_ARROW) then
cls
y1:=y1+10
y2:=y2+10
end if
end loop

I GOT IT!!
i just had to add a short delay before i ended the loop (i am not sure why though)
