[14] Equipment
01/02/2020, 10:41pm
Equipment was a pain. The inventory was already a complex piece of state, and equipment just added more stuff to keep track of. I also had to rework the UI on the client to accomodate this. Now there's a little tabbed menu, with 3 pages: Character, Gear, and Settings. I haven't gotten to make many new models or textures for the equipment yet.
Item Types & Attributes
Item resources now support an an item type, and slot (if the item is equippable). You can also specify a simple attributes table, which allows items to have configurable attributes such as damage, armor, and a healing amount (for consumables). Here's what the item file for the rusty axe looks like:
rusty-axe.toml
id = 8
[item]
name = "Rusty Axe"
description = "Dull, but will chop stuff."
type = "weapon"
slot = "mainhand"
model_id = 0
is_stackable = false
[attributes]
damage = 1
Most of the code was tiny refactors and packet additions, so here's a changelist to sum it up quickly.

- Server: Added 'slot' field to item definitions (for weapons and armor)

Having a full gear set makes it pretty easy to take on the King Chonkrat, the main threat in this test world. Although, I did hack in a better weapon for extra damage. I need to add some more NPCs that drop loot.
Was having fun with the world editor and made this little island. I want to get back to the terrain code soon and start making the world much larger.
