I've been trying to create items and item sets through code for quite a bit now, What i've done is create a new class that basically has some copy-pasta from the ItemPickup.cs in the following way:
* Using the CharacterAssist namespace
* Adding a custom ItemPickup.PickupSet[] that would eventually hold all weapons available in the game
* Fetching the player prefab, inventoryBase, ItemCollection, ItemSetManager and ItemPlacement on demand
* looping through the PickupSet[] on keypress (would later be done through network RPC's) to find an item of a certain type name
* trying to add the coresponding PickupSet to the itemSetManager with eg. itemSetManager.AddItemSet(item, itemset, default);
* instantiate and place the item on the player
* finally add the item to the inventory
So basically just like the pickup script works, just without all the parts about having to actually go to a pickup and collide with it.
The problem i'm facing (for the moment) is that i get an IndexOutOfRangeException: Index was outside the bounds of the array.
Which happens when trying to add the item set to the itemsetmanager, and i'm at a loss for any more ideas on how to fix this so I hope someone here could point me in the right direction.
(Any and all points in the direction of how to accomplish: Adding a variable weapon to the player, and players inventory, so they can equip it, all via Code and not any pre-defined pickup gameobjects placed in the world, will all be extremely helpful, the caveat here is that i don't want to: 1) pre-add the items to the players in editor-mode because the inventories are dynamic and read from a database, 2) use pickup-objects that you have to collide with, since the items once again will be added from the server-side through network RPC's)
Full code in code segment below
EDIT: Found some things to change (base class for one) and now it sort of works, except i have to press '2' twice before a sword is equipped, which feels a bit weird, anyone know why this is?
