Prettier way to fill an array within a function?

Lol. 1 minute reply?

Wow, very nice.

Bit of a weird question, but this is bothering me.

If I want to fill a temporary array within a function, is there a nicer way to do it than this:

local Array<Int> myArray;
myArray.AddItem(1);
myArray.AddItem(2);
myArray.AddItem(3);
myArray.AddItem(4);
...

Well, there is. Use this magic:
https://github.com/RattleSN4K3/UC-MiscArrayOps

With that UnrealScript UCI pre-processor script, you can very much create any array with an inline expression.

    local array<byte> array_byte;
    local array<int> array_int;
    local array<float> array_float;
    local array<string> array_string;
    local array<name> array_name;
    local array<Object> array_object;
    local array<Actor> array_actor;
    local array<class> array_class;

    array_byte = ! byte(1) + 2 + 127 + 255;           // {1,2,127,255}
    array_int = ! 3 + 4 + 42 + 1337;                      // {3,4,42,1337}
    array_float = ! 1.337f + 0.666f;                       // {1.337f, 0.666f}
    array_string = ! "Some" + "Fancy" + "Array";      // {"Some","Fancy","Array"}
    array_name = ! 'Could' + 'be' + 'useful';             // {'Could','be','useful'}
    array_object = ! self + self.Owner + Sprite;       // {MyActor_0,MyPlayerController_0,Sprite}
    array_actor = ! self + self.Owner;                    // {MyActor_0,MyPlayerController_0}
    array_class = ! class'MyInv1' + class'MyInv2';    // {MyInv1,MyInv2}

All you have to do is including this file:
ArrayOp.uci

PS: CobaltUDK's solution is also included:

array_int /= "3,4,42,1337" / ",";

or

array_int = int("") ~= "3,4,42,1337" / ",";

Nice idea. Thanks for the help guys.

local array<string> A;
local string B;

B = "1,2,3,4,5,6,7,8,9,a,b,c,d,e";

A = SplitString(B,",",false);

then A[0] = 1, A[1] = 2, etc.

good for small strings.

You can do a bucle to copy the array to other, converting strings to float or int or what you need.

Not really, no. At least I don't think so.

What you can do is have a function that only contains the array initialization. Or if it is really just a sequence of numbers 1-n, at least use a for loop.
If you're repeatedly using the same array you could think about a static dynamic array initialized in defaultproperties or an array of constant size (not sure if either of these are applicable in your scenario). You may still need to copy that but at least you wouldn't need the initialization every time.

Seems like i should be able to do something like:

local Array<Int>myArray;
myArray = [1,2,3,4];

Thanks in advance
