Post subject: Turing Final Project

I have my turing final project due tomorrow and I decided to post my Q here, in case I do not get a chance to ask my teacher. Basically, my program which is a text-adventure game (through an enchanted forest!) stops at this one part in the middle of my if statement at else, I have no idea why and obv. I need it to work lool. So if you can help please do! Thanks in advance!! I have no idea how to post a file on here, so here's the problem:

code:

if r1 = "nothing" or r1 = "Nothing" then put "Well done! Your smartness is evident. The dwarfs let you" put "go through their portal and you arrive a little late, but" put "what matters is that you are there! Your journey is complete!" put "You have made it with two Fairy Dust left! Type 'again' to" put "replay!" get again if again = "again" or again = "Again" then scene := 1 end if else r1= "No" then put "Wrong answer! You have lost one life!" fd := fd - 1 put "\t\t\t\t\t\t\t\t Fairy Dust: ", fd riddle := 1 end if if fd>=0 then scene:=7 end if end if

Please specify what version of Turing you are using

The other post specifically highlighted else r1= "No" then

The error message might lead towards the answer (it's a syntax error). If not obvious, take a look at tutorial http://compsci.ca/v3/viewtopic.php?t=367 or documentation on if.

[riya]

okay I kind of fixed the error, thanks A TONNE for replying and the tutorial link! My teacher said to just do else and then have what to do like the turing instruction. My problem now is that, when they get it wrong the program is suppose to take them to the riddle again so they can try again but, it doesn't instead, it takes the user to the start which is not what I need it to do. Any suggestions?

end if

if fd >= 0 then
scene := 0
end if

[Tony]

code:

loop    ...    ...    # success, we can move on    exit    ...    ... end loop

use loops to repeat stuff. exit once whatever condition is met.

[riya]

how do I post a file on here? Turing is killing me omg

[riya]

OMG Tony! I got the else to work but, it only works when I have one put statement and if I add another one or anything it crashes. What should I do?

[Tony]

lets see the code. How does it crash (is there an error?)

[riya]

okay this is the code.



if crosspath = "East" or crosspath = "east" then

cls
fd := fd + 0
put "\t\t\t\t\t\t\t\t Fairy Dust: ", fd
Draw.FillStar (0, 0, star, star, yellow)
Draw.FillStar (maxx - star, 0, maxx, star, yellow)
delay (2900)
put "The Unknown: Oh no! The goblin managed to catch up to you!"
put "After demanding one of your precious Fairy Dust and scaring"
put "you very much so, he is off on his way."
delay (1000)
fd := fd - 1
put "\t\t\t\t\t\t\t\t Fairy Dust: ", fd

delay (4000)
put ""
put "The Unknown: After, a little walking you see a sign: LAND OF DWARFS "
put "There you meet Grumpy and Happy, and after a few laughs"
put "they take you over to their portal. You can cross the portal"
put "only on one condition: you must solve their riddle!"
delay (5900)
cls
put "\t\t\t\t\t\t\t\t Fairy Dust: ", fd
Draw.FillStar (0, 0, star, star, yellow)
Draw.FillStar (maxx - star, 0, maxx, star, yellow)
delay (2900)
riddle := 1
put "The Unknown: The riddle is: "
put ""
put "What is more powerful than God?"
put "What is more evil than the Devil?"
put "The poor have it."
put "The rich need it."
put "If you eat it you will die."
put "Hint: The answer is one word! Type in the word: "
get r1
end if


if r1 = "nothing" or r1 = "Nothing" then
put ""
put "The Unknown: Well done! Your smartness is evident. The dwarfs let you"
put "go through their portal and you arrive a little late, but"
put "what matters is that you are there! Your journey is complete!"
put "You have made it with two Fairy Dust left! Type 'again' to"
put "replay!"
get again
else

put "Wrong answer! You have lost one life!"
end if


if again = "again" or again = "Again" then
scene := 1
end if

if fd >= 0 then
scene := 0
end if

if I add anything even another put statement to the else right up there it crashes!

[riya]

and what I need to add to that else is this:
fd := fd - 1
put "\t\t\t\t\t\t\t\t Fairy Dust: ", fd
and then put the loop in to take it back to the riddle, but if i use this loop, will it mess anything else up? I have one big loop for the entire program and many if statements. Will the loop work? I AM SO SORRY FOR BOMBARDING YOU WITH Q'S

[riya]

tony I really need your help

[riya]

nvm I got it! Thanks for your help!

[Tony]

I'm glad that you figured out this particular issue, but I'd like to stress this one important technique for figuring out the problems faster:

- pay attention to the error messages (you haven't mentioned those, even after having been asked).
- in a separate file, find the minimal amount of code that reproduce the same error.

E.g. for an error with a if-else structure, we really don't need all of those puts, delays, and draws. It's difficult to understand large blocks of code, but you can cut it down to a small example

code:

if 1 = 2 then    put "A" else   put "B" end if

and study that. If the error is still there, it will be much easier to find.
