Hi all,

I get this error:

pawn Код:

error 017: undefined symbol "Items@YSII_Ag"

In this piece of code:

pawn Код:

CMD:test(playerid, params[])
{
    new str[50], i;
    foreach(i : Items)
    {
        format(str, sizeof(str), "Slot %d - %s %s", i+1, ReturnItemName(i), ReturnItemCondition(i));
        print(str);
    }
    return 1;
}

Enum:

pawn Код:

enum itemInfo{
    iID,
    iType,
    iCondition
};
new ItemInfo[MAX_ITEMS][itemInfo];

I included both the y_iterate include and foreach include, I can't seem to find the problem here. I hope someone else can.

Could you show how you declared the iterator in the code?
Example:

pawn Код:

new Iterator:Items<...>;

[Dayrion]

PHP код:

new Iterator:Items<MAX_ITEMS>; 


Missing this ^

Not at all, that was the mistake... Thanks anyways!

Thank you!

Now I seem to be running in another problem, it doesn't loop trough the items enum at all.

This is my code now, with added prints for debugging purposes:

pawn Код:

new Iterator:Item<MAX_ITEMS>;
CMD:test(playerid, params[])
{
    print("/test is called!");
    new str[50], i;
    foreach(i : Item)
    {
        printf("print %d", i);
        format(str, sizeof(str), "Slot %d - %s %s", i+1, ReturnItemName(i), ReturnItemCondition(i));
        print(str);
    }
    print("loop is finished");
    return 1;
}

If I type /test IG I get this in my console:
[23:53:20] /test is called!
[23:53:20] loop is finished


Before running that test code I added a velue to the enum:

pawn Код:

CMD:addinv(playerid, params[])
{
    new item, condition, slotid;
    if (!IsAdminAuthorized(playerid, 1, 0))
        return SendErrorMessage(playerid, "You are not authorized to use this command.");

    if (sscanf(params, "ddd", slotid, item, condition))
        return SendSyntaxMessage(playerid, "Usage: /addinv [slot] [item] [condition]");

    new id = CheckNearestItemSlot();

    ItemInfo[id][iID] = id;
    ItemInfo[id][iType] = item;
    ItemInfo[id][iCondition] = condition;
    PlayerInventory[playerid][pInvSlot][slotid] = id;
    
    return 1;
}

Alriight. You probably don't have what custom iterator does. You should read this carefully : https://sampforum.blast.hk/showthread.php?tid=570937

From what I understand about y_iterate, shouldn't you be calling Iter_Add to add something to the iterator? If you don't add something to it, there's nothing to iterate.

You should revise programming terms used in Pawn. You don't "add" a value to enum, an enum is a collection of named constants that can be also used to describe the contents of an array.

But to say something more helpful to you, you are combining two completely unrelated things - you use slot-based inventory to store the item, and then you try to retrieve all items in the inventory using a completely isolated iterator. You should use something akin to this:

Код:

for(new slotid = 0; slotid < sizeof(PlayerInventory[playerid][pInvSlot]); slotid++)
{
    new itemid = PlayerInventory[playerid][pInvSlot][slotid];
    if(itemid != 0) //if you use 0 for empty slot
    {
        printf("Slot %d - %s %s", slotid, ReturnItemName(itemid), ReturnItemCondition(itemid));
    }
}
