Get value at index with foreach - Aviicix - 11.04.2017

Hi guys,

I have a foreach iterator which stores some array indexes and I use it in a dialog, now I need to access the original array at the index stored in the "listitem" index of the foreach iterator, someone know how can I do this?

e.g:

pawn Код:

new IntArray[][E_INT_INFO] = {
{0.0000, 0.000, 3.000},
{124.1524, -67.2987, 1.5782}
// ...
};

Iter_Add(IntIter, 1); // Adding the second element of IntArray
Iter_Add(IntIter, 7);

Now, when I use the foreach in the dialog it shows IntArray[1] at index 0 intArray[7] at index 1 and so on..
I'd like to get the value from the foreach iterator at index "listitem" (Intiter[listitem])

Thank you for replying ******,
I'm using foreach standalone 0.4 and there's no such function, what version do I need to download ?

Try with ysi

Re: Get value at index with foreach - Aviicix - 12.04.2017

I've checked the YSI github repository looking for y_iterate and foreach and I didn't find any Iter_Index function, I read something about this function on Gammix's foreach but I don't want to rewrite all the things I've already made

Yeah, there is no Iter_Index function, i've checked.

Re: Get value at index with foreach - Aviicix - 13.04.2017

I fixed it by making this function:

PHP код:



#define Iter_Index(%1,%2) Itter_Index(_Y_ITER_ARRAY:%1@YSII_Ag,%2,_Y_ITER_ARRAY_SIZE(%1))


stock Itter_Index(array[], index, size)

{

    new cont = 0,

        last = size,

        next = array[last];

    while(cont < index)

    {

        last = next;

        next = array[last];

        cont++;

    }

    return next;

}

Use:

PHP код:



new value = Iter_Index(IteratorName, index);

PHP код:



new Iterator:test<5>;

Iter_Add(test, 4);

Iter_Add(test, 0);

Iter_Add(test, 2);


Iter_Index(test, 1); // return 2 as the array will be ordered in ascendent order

IntArray is constant array...why would you need to use foreach instead of while/for ?

Re: Get value at index with foreach - Aviicix - 14.04.2017

You're right but what I've posted right there is the testing code I was trying, I needed foreach because instead of making other class-specific array which will just be a waste of memory I decided to store the indexes of the elements of a specific sub-class on his specific iterator.
