Need some help to improve my game in turing

[Anastasia]

Hi guys!
I'm trying to make a game in turing based on Zork game. ( But much simpler)
Have some problems though...don't know how to get rid of them...

like in the part where it says "You're facing the east of the house. There is a cracked window. If you want to open and enter the window enter 'in'"
and when I enter 'in' first time the program says "I don't understand" and when I enter it second time the program says what I want for it to say the first time.

PLEASE HELP.....

[b]SORRY FOR ANY GRAMMAR MISTAKES....ENGLISH IS NOT MY FIRST LANGUAGE

Here is what I've got so far.....

Turing:

%outside of the house %north procedure northSideOfHouse     put ""     put "You're facing the north side of the house."     put "There are two windows. Both window are boarded and cannot be open." end northSideOfHouse %south procedure southSideOfHouse     put "You're facing the south side of the house."     put "The door and the two windows are boarded and cannot be open." end southSideOfHouse %east procedure eastSideOfHouse     put "You're facing the east of the house."     put "There is a cracked window. If you want to open and enter the window enter 'in'" end eastSideOfHouse %west procedure westSideOfHouse     put "You're facing the west side of the house."     put "There is three boarded windows that cannot be open." end westSideOfHouse %kitchen procedure kitchenOfHouse     put "You are in the kitchen of the Dark House."     put "A table seems to have been used for the preparation of food."     put "A passage leads to the west."     put "To the east is a small window which is open."     put "On the table is an elongated brown sack, smelling of hot peppers."     put "To go west enter 'w'" end kitchenOfHouse %living room procedure livingRoom     put "You are in the living room. There is a door to the east."     put "To the south is a wooden door with strange gothic lettering,"     put "which appears to be nailed shut."     put "To the west is a big closet door, with a key in it."     put "In the center of the room is a large oriental rug."     put "There is a trophy case here."     put "On hooks above the mantelpiece hangs an elvish sword of great antiquity."     put "A battery-powered brass lantern is on the trophy case."     put "There is an issue of 'Toronto Star' dated 11-MAR-02 here."     put "(choose the direction)" end livingRoom %south procedure livingRoomSouth     put "The wooden door with stange gothic lettering, is nailed shut, and cannot be open" end livingRoomSouth %west procedure livingRoomWest     put "In front of you is a big closet door, with a key in it. To open the closet type in 'key'" end livingRoomWest % Open Closet procedure closet     put "The closet door is open and you can see a dark tunnel leading towards a"     put "faint light. To enter the close and go through the tunnel enter 'go'" end closet % inside the closet procedure twoDoors     put "You entered the closet and went though the tunnel."     put "You are standing in a small room, dimly light by one bulb."     put "You see two doors. One to your right and one to your lefgt."     put "Behind the right door, you can hear the scweecking of rats."     put "Behind the left door, you don't hear anything but you can feel"     put "that something and behind that door. It is hard desision for"     put "you to make which door you need to open. " end twoDoors % dont understand procedure doNotUnderstand     put "I don't understant" end doNotUnderstand % Start of the game colourback (black) cls colour (white) put "Welcome!" colour (white) put "You're standing to the south side of the Dark House." colour (white) put "There is a note at your feet. To read the note, type in 'read'" %variables var action : string var actionTwo : string var actionThree : string var actionFour : string var actionFive : string %read the note put "" colour (white) get action if action = "read" then     put "Hi there! (Rules of the game) choose the direction: to go north type in 'n',"     put "to go south type in 's', to go west typein 'w', and to go east type in 'e'" else     put "Read the note!" end if loop     % outside of the house     put ""     colour (white)     get actionTwo     if actionTwo = "n" then         northSideOfHouse     elsif actionTwo = "e" then         eastSideOfHouse     elsif actionTwo = "w" then         westSideOfHouse     elsif actionTwo = "s" then         southSideOfHouse     else         doNotUnderstand         %kitchen of the house         put ""         get actionThree         if actionThree = "in" then             kitchenOfHouse         else             doNotUnderstand         end if         %living room of the house         put ""         get actionThree         if actionThree = "w" then             livingRoom         else             doNotUnderstand             put ""             get actionFour             if actionFour = "s" then                 livingRoomSouth             elsif actionFour = "w" then                 livingRoomWest             elsif actionFour = "e" then                 kitchenOfHouse             else                 doNotUnderstand             end if             % Closet             put ""             get actionFive             if actionFive = "key" then                 closet             else                 doNotUnderstand             end if         end if     end if end loop

It is not finished....
Also, I would appreciate any suggestions on how to improve my game.

Thanks in advance...

You are handling first and second inputs with different get statements; so your second answer is for a different part of the code, so it's handled differently.

[Zren]

Open up a new program and type break. Run that program. The editor will now enter a sort of debuging mode. Checkmark trace execution. Go back to your origional application and run it. Watch how the logic runs. To exit the debuging mode, you have to close and reopen Turing.

That should hint at your error.

Hint:
- You need a variable to distinguish where you are.

To Zren:
ok I did what you said....
still don't understand how change it.....

I don't really understand what you mean by
"You need a variable to distinguish where you are."

Right now that information is encoded in the structure of your if-statements (and you leave comments for yourself). You could also track that location (where the character is) in a variable, which makes some things much easier to do. E.g.

code:

put "kitchen of the house" % which could be generalized to 'put character_location'         put ""         get actionThree

Not as a part of the final game, but just for the development process. A common approach are flags to turn this information on/off

code:

if DEBUG_MODE then    put character_location end if

This gives you two pieces of information:
1. What state you've set your character in.
2. What line of code is executing at the time.

OK
that makes sense
Thanks!

I have a question.....

if want to use an "exit when" statement
can I wright it like that?

Turing:

loop     put ""     get actionThree     if actionThree = "go" then         twoDoors             else         doNotUnderstand          exit when actionThree = "go"     end if end loop

[Zren]

Infinite loop. You never exit because you're contradicting yourself. When a3 is not "go" then you enter the else statement. Then you exit if it does equal "go", which isn't possible since you already filtered out that it isn't "go".

An exit when is pretty much a combined if statement + exit.

Turing:

loop     exit when true end loop loop     if true then         exit     else     end if end loop

[Anastasia]

ok but what if i need to have statement that says: " there are 2 doors" and then exit?
like in my example

should I put exit when at the end or like that:

Turing:

loop     put ""     get actionThree     if actionThree = "go" then        put  "there are 2 doors"  exit when actionThree = "go"             else         doNotUnderstand             end if end loop

where exit when follows the 'put' statement?

[Zren]

That's correct. Just going to point out again, don't need to check if it's "go" again, as you already know that when you entered the if statement. Using just exit works the same.

Turing:

loop     put ""     get actionThree     if actionThree = "go" then         put "there are 2 doors"         exit     else         doNotUnderstand     end if end loop

[Anastasia]

oh OK...

I got it now thanks so much!
