Rpg Shop...

[Unicornzrcool]

Ok, here's my question, in the code below I have a shop scenario and the option to buy a weapon and a shield. However, you are able to buy as many of one item as you want. I was wondering if there was some way to change the code so you can only buy 1 of the object. Any help would be greatly appreciated!! =]

Turing:

var money : int var damage : real var armor : real var option1 : real var option2 : real var buy1 : string money := 50 damage := 0 armor := 0 put "congratulations, you have learned how to fight!" put "now that you have some money, lets go buy some new equipment" put " " put "press any key to continue to the shop" Input.Pause cls loop     put "welcome adventurer, please feel free to look around"     put " "     put "here are the items we currently have for sale"     put " "     put " "     put "1. Metal sword"     put "2. Wooden shield"     put " "     put "you currently have ", money, " gold!"     put "your weapon score is ", damage, "!"     put "your armor score is ", armor, "!"     put " "     put "please select an item to find out more"     get option1     if option1 = 1             then         cls         put "The Metal sword"         put " "         put "The Metal sword is a fine weapon for beginners and will do"         put "more damage than a Wooden sword."         put " "         put "Dmg + 15"         put "Costs 23 gold"         put " "         put "Would you like to buy this sword?"         get buy1         if buy1 = "y"                 then             cls             if money > 23                     then                 put "a fine choice"                 damage := damage + 15                 money := money - 23                 put " "                 put "press any key to go back to the shop"                 Input.Pause                 cls             elsif money < 23                     then                 put "sorry you do not have enough money"                 put " "                 put "press any key to go back to the shop"                 Input.Pause                 cls             end if         elsif buy1 = "n" then             cls         end if     elsif option1 = 2             then         cls         put "The Wooden Shield"         put " "         put "The Wooden Shield will protect the user and provide"         put "more damage reduction."         put " "         put "Arm + 10"         put "Costs 20 gold"         put " "         put "Would you like to buy The Wooden Shield ?"         get buy1         if buy1 = "y"                 then             cls             if money > 23                     then                 put "a fine choice"                 armor := armor + 10                 money := money - 20                 put " "                 put "press any key to go back to the shop"                 Input.Pause                 cls             elsif money < 23                     then                 put "sorry you do not have enough money"                 put " "                 put "press any key to go back to the shop"                 Input.Pause                 cls             end if         elsif buy1 = "n" then             cls         end if     end if end loop

var metalsword : bool := false

if the player buys the sword, set it to true
if metalsword is true, then make it so they cant buy it.

Ok, I followed your instructions and it stops the player from buying more than one sword. However, it skips the part where it is supposed to say "you have already bought this item". Here is the code again with the part you said to add:

Turing:

if option1 = 1             then         cls         put "The Metal sword"         put " "         put "The Metal sword is a fine weapon for beginners and will do"         put "more damage than a Wooden sword."         put " "         put "Dmg + 15"         put "Costs 23 gold"         put " "         put "Would you like to buy this sword?"         get buy1         if buy1 = "y"                 then             cls             if money > 23 then                 if metalsword = false then                     put "a fine choice"                     damage := damage + 15                     money := money - 23                     metalsword := true                     put " "                     put "press any key to go back to the shop"                     Input.Pause                     cls                 end if             elsif money < 23 then                 put "sorry you do not have enough money"                 put " "                 put "press any key to go back to the shop"                 Input.Pause                 cls             elsif metalsword = true then                    put "sorry but you have already bought this item"                 put " "                 put "press any key to go back to the shop"                 Input.Pause                 cls              end if         elsif buy1 = "n" then             cls

Is this even the correct way to put it in, and if so is there any way of making it so that it allows me to say that?
Thanks!

btw, what happens when you have exactly 23 gold :S

[Unicornzrcool]

Haha nice I didn't notice that before.
Thanks for pointing that out!

why is

code:

elsif metalsword = true %wheee.... end if

combined with the money checking if statement? think about how if/elsifs work.

Turing:

if money > 23 then     %do some stuff.     /*-------     if we get to this point, the elsifs WILL NOT BE CHECKED.     -------*/ elsif money < 23 then %IF money is not > 23, we check this, otherwise it is ignored.     %More stuff done.     /*------     if we get to this point, any elsifs/else's below this point WILL NOT BE CHECKED     ------*/ elsif metalsword = true then %IF money not > 23 and not whatever condition 2 was, check this, otherwise, ignore it.     %we wont get here UNLESS the user has Exactly $23 AND does not have a metal sword.     %tell user off for being an idiot and trying to buy 2 of the same item. end if

it would make more sense if you combined the metalsword = true in to the same if then else statement as the metalsword = false.
