Can anyone shed array of hope?

[Marukamu]

Bad pun, yes, I know, but that's not the point.

I've used arrays before in other programming languages, and the array seems to differ between languages. What I want to know is how arrays are used in Graal ( the command panel is not much help... ), and are they saved in any way like flags are?

What I am trying to do is use an NPCW to store certain settings in an array, and when necesary, display them in a GUI, and the data I want to store may not always be the same.

You proablly will benifeit from using string lists besides arrays if you want to store text.

CREATING ARRAYS
1) setarray name,length;
Will create a new array with the specified length which will be identified with the specified name.

2) arrayname = {0,0,..};
Same as above, but you can specify what will be in the array. (e.g. settings = {1,4,0,1,1,3}

ARRAY INDEXES
1) You must first create an array before you can access it. To access an array, then use "arrayname[#]" where # is the index you want to access. Also, indexes start at 0. So if you use:

NPC Code:

---

setarray settings,6;

---

Then the last index in the array will be 5.

2) To change something in an array, just use:

NPC Code:

---

name[i] = #;

---

name: The name of the array you wish to access
i: The index in which you want to change the value of
#: The value you want to set the accessed array index to
(Note: Regular arrays can only hold variables.)

3) If you want access something from an array, but not change it, just use something such as:

NPC Code:

---

if (playerchats && strequals(#c,show hp)) {

  setplayerprop #c, #v(attributes[2]);

}

---

Have I missed anything (besides string arrays)?

String lists is probably want you want to use.

sarraylen(str)
#I(list,text)
addstring list,text
insertstring list,text,index

There's a few other commands they you will find useful listed in the newfeatures text file.

If you've ever done C++ then it is similar. You can't use an array until it has been created. Therefore setarray <variable_name>,length; will create the var array, or this.var={0,1,2,3};
But I don't really think of strings as using arrays, as it is basically one string with quotations and commas
Addstring <string name>,<value>; is a common use, it adds it to the end. Replace string, insertstring, etc. are in commands.rtf file. To access it you use #I. #I(string,position)

Graal C++ will be better for datastorage, but in the mean time, I have to explain that GScript Variables cannot be strings... Strings are seperate.

Basically an array of string values is a string, delimited by commas or spaces (quotes will group strings, so you can include commas and spaces, eg string1=cat,dog,chicken,Super Cow; would be a string array of 5 strings, where as string2="cat,dog",chicken,"Super Cow"; would be 3)

other than that arrays are pretty much the same as C++, they just dont have to be declared, and they can be resized with setarray.

so

setarray array,3;
array[0] = 1;
array[1] = 2;
array[2] = 3;

and

array={1,2,3};

are both perfectly legal, although the latter is prefered (the first one resembles VB, and VB is posible the worst language X_X)
