lights game (help)

i am writing a program using the parallel port for my computers class and i got myself stuck.
For the program, we needed to use 1 button an 8 LED lights.
My program flashes random led lights, and you need to press the key on the keyboard that corresponds to the light shown before the next light appears.

i have 3 main parts, the button, random lights, and keyboard commands.
the part i need help with is connecting the keyboard commands with the flashing lights, such as

code:

if parallelput=1 'and you press a', put "good"
else end process/procedure

or something along that line.
My full code is:

code:

var x : int
var no1 : int
var keys : array char of boolean

put "Press the button to start"
put ""
loop
x := parallelget
if x = (56) then
cls
put "3..."
delay (1000)
cls
put "2..."
delay (1000)
cls
put "1..."
delay (1000)
cls
put "GO!"
delay (1000)
cls
end if
end loop

%Random lights displayed

loop
no1 := Rand.Int (0, 7)
put (2 ** no1)
delay (600)
end loop

loop
Input.KeyDown (keys)
if keys (chr (97)) then
put "good"
delay (160)
elsif keys (chr (115)) then
put "s"
delay (160)
elsif keys (chr (100)) then
put "d"
delay (160)
elsif keys (chr (102)) then
put "f"
delay (160)
elsif keys (chr (104)) then
put "h"
delay (160)
elsif keys (chr (106)) then
put "j"
delay (160)
elsif keys (chr (107)) then
put "k"
delay (160)
elsif keys (chr (108)) then
put "l"
delay (160)
end if
end loop

please help me cause my teachers is too lazy to help anyone in the class.

Re: lights game (help)

You have 3 infinite loops, the first one is never left, so i would recommend combining them otherwise code after will never be read, or exiting loops under a condition.

when you have:

code:

if keys(chr(97)) then

you could replace with:

code:

if keys('a') then

for easy reading

but since you want to check whether or not its the right light, you should be doing something like:

code:

if keys('a') and no1=1 then

this will check whether or not the a character is pressed, and the no1 which corresponds to the last output to the board (which is the number of the led im guessing if i look at your code)

Hope This Helps.

Re: lights game (help)

ok i tired the statement, and it works, but i'm trying to make it if you press it at the wrong time the procedure ends or process ends if possible.

this code puts random numbers, but it puts "you lose" after every number, also without the else statement, i have to wait a certain amount of time before the letter shows up, is it because of the delay?

code:

procedure two
loop
no1 := Rand.Int (0, 7)
put (2 ** no1)
delay (1000)

Input.KeyDown (keys)
if keys ('a') and no1 = 0 then
put "a"
delay (1)
else put "you lose"
end if
end loop
end two

two

Re: lights game (help)

This is a very rough way to do it, i do not recommend doing it this way, but by looking at this way i hope you can find a better way to do it, the idea is the same, just its not the correct way to do.

code:

var no1 : int
var keys : array char of boolean
var dlayCount : int := 0

loop
no1 := Rand.Int (0, 7)
put (2 ** no1) ..
put "-", no1
loop
delay (10)
dlayCount += 10

Input.KeyDown (keys)
if keys ('a') and no1 = 0 then
put "Correct 'a'"
dlayCount := 0 % Reset Count
delay (2000) % So Next Round Is Not Instant
exit
elsif keys ('a') and no1 not= 0 then % If Press Key and Not Number!
put "you lose"
dlayCount := 0 % Reset Count
delay (2000)
exit
end if

if keys ('s') and no1 = 1 then % if hitting a, but isnt led 1 then
put "Correct 's'"
dlayCount := 0 % Reset Count
delay (2000) % So Next Round Is Not Instant
exit
elsif keys ('s') and no1 not= 1 then
put "you lose"
dlayCount := 0 % Reset Count
delay (2000)
exit
end if

if dlayCount = 1000 then % Time Out
put "you lose"
dlayCount := 0
exit
end if
end loop
end loop

Re: lights game (help)

thanks a lot, it actually works now, but how would you make it where if you get the letter wrong it stops the game instead of saying "you lose"?
i tried this but it still

code:

if keys ('a') and no1 = 0 then
put "Correct 'a'"
dlayCount := 0
delay (1000)
exit
elsif keys ('a') and no1 not= 0 then
exit
end if

code:

var no1 : int
var keys : array char of boolean
var dlayCount : int := 0

procedure two
loop
no1 := Rand.Int (0, 7)
put (2 ** no1) ..
put " (", no1 + 1 ..
put ")"
loop
delay (10)
dlayCount += 10

Input.KeyDown (keys)
if keys ('a') and no1 = 0 then
put "Correct 'a'"
dlayCount := 0
delay (1000)
exit
elsif keys ('a') and no1 not= 0 then
put "you lose"
dlayCount := 0
delay (1000)
exit
end if

if keys ('s') and no1 = 1 then
put "Correct 's'"
dlayCount := 0
delay (1000)
exit
elsif keys ('s') and no1 not= 1 then
put "you lose"
dlayCount := 0
delay (1000)
exit
end if

if keys ('d') and no1 = 2 then
put "Correct 'd'"
dlayCount := 0
delay (1000)
exit
elsif keys ('d') and no1 not= 2 then
put "you lose"
dlayCount := 0
delay (1000)
exit
end if

if keys ('f') and no1 = 3 then
put "Correct 'f'"
dlayCount := 0
delay (1000)
exit
elsif keys ('f') and no1 not= 3 then
put "you lose"
dlayCount := 0
delay (1000)
exit
end if

if keys ('h') and no1 = 4 then
put "Correct 'h'"
dlayCount := 0
delay (1000)
exit
elsif keys ('h') and no1 not= 4 then
put "you lose"
dlayCount := 0
delay (1000)
exit
end if

if keys ('j') and no1 = 5 then
put "Correct 'j'"
dlayCount := 0
delay (1000)
exit
elsif keys ('j') and no1 not= 5 then
put "you lose"
dlayCount := 0
delay (1000)
exit
end if

if keys ('k') and no1 = 6 then
put "Correct 'k'"
dlayCount := 0
delay (1000)
exit
elsif keys ('k') and no1 not= 6 then
put "you lose"
dlayCount := 0
delay (1000)
exit
end if

if keys ('l') and no1 = 7 then
put "Correct 'l'"
dlayCount := 0
delay (1000)
exit
elsif keys ('l') and no1 not= 7 then
put "you lose"
dlayCount := 0
delay (1000)
exit
end if

if dlayCount = 1000 then
put "you lose"
dlayCount := 0
exit
end if
end loop
end loop
end two

Re: lights game (help)

Well the easiest way would be to actually make a boolean called isEndofGame or isGameOver. the reason why i put is before is to make sure its boolean in terms of reading the code.

set it to false on start, and then make a exit when isGameOver in the outer infinite loop ontop of that exit.

code:

elsif keys ('a') and no1 not= 0 then
isGameOver:=true
exit
end if

Re: lights game (help)

ok i'm confused. what kind of variable should gameover be? boolean? i tried this but it doesnt change anything...

code:

var no1 : int
var keys : array char of boolean
var dlayCount : int := 0
var isgameover : boolean

procedure two

loop
isgameover := false
no1 := Rand.Int (0, 1)
put (2 ** no1) ..
put " (", no1 + 1 ..
put ")"
loop
delay (10)
dlayCount += 10

Input.KeyDown (keys)
if keys ('a') and no1 = 0 then
put "Correct 'a'"
dlayCount := 0
delay (1000)
exit
elsif keys ('a') and no1 not= 0 then
isgameover := true
exit
end if

god dammit i want to finish this project already Mad

Re: lights game (help)

Something like this.....

code:

var no1 : int
var keys : array char of boolean
var dlayCount : int := 0
var isNextRound : boolean := false
var isGameOver : boolean := false

procedure nextRound
dlayCount := 0
delay (2000)
isNextRound := true
end nextRound

loop
exit when isGameOver=true
isNextRound := false
no1 := Rand.Int (0, 7)
put (2 ** no1) ..
put "-", no1
loop
delay (10)
dlayCount += 10

Input.KeyDown (keys)
if keys ('a') then
if no1 = 0 then
put "Correct 'a'"
else
put "you lose"
isGameOver := true
end if
nextRound ()
end if

if keys ('s') then
if no1 = 1 then
put "Correct 's'"
else
put "you lose"
isGameOver := true
end if
nextRound ()
end if

if dlayCount = 1000 then % Time Out
put "You Took Too Much Time!"
nextRound ()
end if

exit when isNextRound
end loop
end loop
put "GameOver!"

Re: lights game (help)

alright, i finished it! My final game is...
i hope it works if you change the put Rand.Int, with parallelput Rand.Int, or i'm screwed XD

thanks for the help Hltrahex!

code:

var x : int
var no1 : int
var keys : array char of boolean
var dlayCount : int := 0
var isNextRound : boolean := false
var isGameOver : boolean := false

procedure one
put "Press the button to start"
put ""
loop
x := parallelget
if x = (56) then
cls
put "3..."
delay (1000)
cls
put "2..."
delay (1000)
cls
put "1..."
delay (1000)
cls
put "GO!"
delay (1000)
cls
end if
end loop
end one

procedure nextRound
dlayCount := 0
delay (1000)
isNextRound := true
end nextRound

procedure two
loop
exit when isGameOver = true
isNextRound := false
no1 := Rand.Int (0, 7)
put (0)
put (2 ** no1) ..
put "-", no1 + 1
loop
delay (15)
dlayCount += 10

Input.KeyDown (keys)
if keys ('a') then
if no1 = 0 then
put "Correct!"
else
put "You Lose"
isGameOver := true
end if
nextRound ()
end if

if keys ('s') then
if no1 = 1 then
put "Correct!"
else
put "You Lose"
isGameOver := true
end if
nextRound ()
end if

if keys ('d') then
if no1 = 2 then
put "Correct!"
else
put "You Lose"
isGameOver := true
end if
nextRound ()
end if

if keys ('f') then
if no1 = 3 then
put "Correct!"
else
put "You Lose"
isGameOver := true
end if
nextRound ()
end if

if keys ('h') then
if no1 = 4 then
put "Correct!"
else
put "You Lose"
isGameOver := true
end if
nextRound ()
end if

if keys ('j') then
if no1 = 5 then
put "Correct!"
else
put "You Lose"
isGameOver := true
end if
nextRound ()
end if

if keys ('k') then
if no1 = 6 then
put "Correct!"
else
put "You Lose"
isGameOver := true
end if
nextRound ()
end if

if keys ('l') then
if no1 = 7 then
put "Correct!"
else
put "You Lose"
isGameOver := true
end if
nextRound ()
end if

if dlayCount = 1000 then % Time Out
put "You Took Too Much Time!"
isGameOver := true
end if

exit when isNextRound
end loop
end loop
put "GameOver!"
end two

I'm not too sure, as I haven't dealt with peripherals in Turing, but I believe parallelput takes an integer argument, so Rand.Int should be okay to pass... Also, his name is Ultrahex, not Hltrahex

RE:lights game (help)

yeah, i tested it out at school and i needed to add another var so the button ends and the actual game starts.

code:

var isButtonOver : boolean := true
procedure one
put "Press the button to start"
put ""
loop
isButtonOver:=true
x := parallelget
if x = (56) then
cls
put "3..."
delay (1000)
cls
put "2..."
delay (1000)
cls
put "1..."
delay (1000)
cls
put "GO!"
delay (1000)
cls
exit when isButtonOver = true
end loop
end one

and sorry bout the misspelling, i was typing fast.
