SSE array size as variable?

[dizietemblesssma]

I have the following function:

String Function dz_form_array_item_names(Formlist list)

int j

j = list.GetSize()

string[] names

;string name

names = new string[j]

int i

i = 0

While i < j - 1

  names[i] = list.GetAt(i) as string

  ;names[i] = name

  i = i + 1

EndWhile

Return names as string
EndFunction

unless I comment out the line:

names = new string[j]

 

I get the compile error:

dz_auto_outfit_mcm_menu.psc(647,20): mismatched input 'j' expecting INTEGER

 

the purpose of this function is to return a list of the display names of the items in the formlist, I know that the formlist is not empty from other debugging statements, I'm assuming the reason this does not give me anything other than an empty array is becasue the array 'names' is not initialised, but how to do that?

Your approach is wrong!

;--------------------------------------------------
 String FUNCTION dz_form_item_values(Formlist list)
;--------------------------------------------------
    string s                    ; local string variable is empty by default

int m = list.GetSize()
int i = 0
    WHILE (i < m)                                ; from GetAt(0) up to GetAt(max-1)
        s = s + (list.GetAt(i) as String)        ; save into string
        s = s + ","                              ; add separator
        i = i + 1
    ENDWHILE

    RETURN s        ; return the local string to caller function or event
ENDFUNCTION

Oh cŵl thanks.

For info, do you know why the line:

names = new string[j]

would give the compile error that j is not an integer?

since:

j = list.GetSize()

 

I'll try your code, it seems simpler, I did not know you could concatenate strings like that:)

Because in this instance a literal integer is required. A variable will not work. It is explained on the page about Arrays at the CK Wiki

 

You cannot use a variable or expression to specify the length of an array - it must be declared with an Integer Literal.

Ah, that seems restricting, but then I'm not a programmer:)

It's another one of those "if Papyrus was built using C++ then why does it carry so many restrictions" things..
