Custom Inventory system: void argument not assigned properly?
I'm working on an inventory system and this script is for the equip part of that system. I have five slots to equip items and they work if I equip stuff manually. But now I am trying to write a void to equip them a bit easier. To get there I have this setup:
void Update () {
if (Input.GetButtonDown("Up")) {
equipItem (0, ItemType.Cap, cap);
print (cap.itemID);
}
}
and the void it self:
public void equipItem (int id, ItemType type, Item slot) {
for (int i = 0; i < database.items.Count; i++) {
if (database.items[i].itemID == id && database.items[i].itemType == type) {
slot = database.items[i];
print (cap.itemID);
print (slot.itemID);
}
}
}
Print (cap.itemID) returns as -1 (an empty Item) slot.itemID return as 0 (the ID that it is supposed to be). Did I make a mistake assigning the void arguments or is what I am trying to just dumb, and not possible/not the way to do it?
UPDATE: So the problem is that the Item "slot" get's changed but not the Item "cap" that should have been there in place of the Item "slot". I got it working by changing the whole void in to an new item, this way i could say cap = equipItem ( 0, itemTyp.Cap); and get what I want for now, problem is I also want to be able to acces this from other scripts.
UPDATE2: Never mind I can just find this script by tagging the object it is attached to.
Paramters are local variables. Whatever you do to the variable slot within equipItem will not matter outside of it. You can return a value and assign it to "cap" doing this:
cap = equipItem (0, ItemType.Cap);
and
public Item equipItem (int id, ItemType type)
{
Item slot = null;
for (int i = 0; i < database.items.Count; i++)
{
if (database.items[i].itemID == id && database.items[i].itemType == type)
{
slot = database.items[i];
print (cap.itemID);
print (slot.itemID);
}
}
return slot;
}
Yeah, I figured that out myself as well (it is in the update). Thanks anyway!
