Help with code

FOR x = 1 to 16
IF invspace+str$(x) = "" THEN
LET invspace+str$(x) = "fathersword"
LET x = 16
END IF
NEXT

I need to make x become part of the code so it's like saying if x was 1 then

IF invspace1 = "" THEN
LET invspace1 = "fathersword"
LET x = 16
END IF

The let x = 16 ending the code.
What am I doing wrong. (sorry this is probably one of the only times I've done a for next code in SC) And will x = 16 end the code, because I don't want every single inventory space written as the same item.

So this code is supposed to find a empty space in the inventory and then put the sword into just that space?

[Xiphos]

Yeah. That's a good way to put it in simple words... Something I'm not too good at.


But it doesn't work because the inventory+str$(x) isn't proper syntax. I don't know what the correct syntax is. I also have a few other questions about the code somewhere in there.

You want an array for the inventory variable. You can't create a variable with a custom name like that.

I would make a fake string array of the inventory spaces (just a string that looks like "blank,blank,sword,blank" or something) and then use the MID$ or NHFIELD$ trick to cycle through each inventory field in a for loop. SC doesn't support real string arrays yet so you have to use this trick.

[Xiphos]

Okay I'll do that thanks. But if you replace once blank with something would it be limited to 5 letters?

Sc does...

Code: [Select]

DIM myArray$(4)
LET myArray$(1) = "YO!"
LET myArray$(2) = "HEY!"
LET myArray$(3) = "SUP!"
LET myArray$(4) = "HI!"
FOR i = 1 to COUNTARRAY(myArray$)
 Â  PRINT myArray$(i)
NEXT

Stick that in open card event and watch what happens.

EDIT: Here's an example of the inventory system as an array.
Open Card/Game

Code: [Select]

DIM inventory$(16)

Elsewhere

Code: [Select]

FOR x = 1 to COUNTARRAY(inventory$)
 Â  IF inventory$(x) = "" THEN 
 Â        LET inventory$(x) = "fathersword" 
 Â        LET x = COUNTARRAY(inventory$)
 Â  END IF 
NEXT

EDIT2: For some reason it appears that the help syntax in Sc for arrays is out of date. I'll have to warn Mike. Says there aren't any string arrays yet.

[WarHampster]

I just thought about this and realized that its even easier than that. Just use the REPLACE$ command, that replaces the first instance of oldstring in sourcestring with newstring. So in your case it will automatically replace the first blank spot with the new item. As for your question, I would assume that the new string is not limited to the same length as the oldstring.

EDIT - forget all that, I thought string arrays weren't implemented yet.

Thanks for everything guys. Inventory added to game!
