adds the Vorpal Scythe, a special chaplain null rod variant, replacing the Reaper Scythe, a not so special null rod variant. When you choose the vorpal scythe, it comes as a shard that you implant into your arm, similar to a cursed katana. Once implanted, you can draw it at any time like an arm implant. However, sheathing it again presents some problems. (Also, implanting the organ gives you ``TRAIT_MORBID``, which I'll explain in a bit) The Vorpal Scythe has 10 force, one of the weakest null rod variants for force that isn't a joke null rod. However, it has exceptional armor pen and also has 2 tiles of reach. So quite unique. It also has a special beheading ability when you right-click someone. This borrows some code from amputation shears, functioning pretty similarly, except with a few additional ways to speed up the action and restrictions. (It takes 15 seconds baseline to behead someone standing and conscious, and speeds up or slows down based on factors such as incapacitation and whether or not our scythe is already empowered) When you successfully behead someone with a mind, the vorpal scythe gains 20 force and can be safely stowed and drawn for 2 minutes. Performing more death knells like this will reset the timer. If it has not performed its 'death knell', or you haven't hit a living mob, then it will cause severe damage to you if you ever try and stow it (or its forced back into your arm). Just hitting a mob with the scythe will sate it for 4 minutes. Unless it is a non-player monkey. Horrible things. Just hitting mobs does not reset the timer on empowerment. What this means is that the chaplain may be more hesitant to simply draw their weapon on people. It also means that potentially, the chaplain will not always have magic immunity, since they may end up stowing the weapon away and be reluctant to draw it on a whim without either taking damage for sheathing it without hitting something, or dealing with having one less hand up until they can. While empowerment only happens when you behead mobs with a mind, beheading monkeyhumans and other mindless humans subtypes causes their heads to become haunted! It's mostly harmless and largely just SpOoKy. We don't want heads with actual players in them to go floating off to space. (Does not work on monkey heads for sanity reasons) When you have the Morbid trait, you think creepy stuff is cool and hate saving peoples lives. You get a mood boost from graverobbing, autopsies, dissections, amputations (including beheadings with the scythe and amputations with the shears) and revival surgery. However, you get a mood penalty when you tend wounds on the living, as well as a hefty penalty when you perform CPR or defibrillate someone. I was thinking Victor Frankenstein when I was choosing which actions had an associated moodlet, so anything that I might have missed would be appreciated. You also count as potentially cool with regards to haunted objects. Ghosts think you're neat. (Revenants probably will still kill you if they had the chance)
AI controllers
Introduction
Our AI controller system is an attempt at making it possible to create modularized AI that stores its behavior in datums, while keeping state and decision making in a controller. This allows a more versatile way of creating AI that doesn't rely on OOP as much, and doesn't clutter up the Life() code in Mobs.
AI Controllers
A datum that can be added to any atom in the game. Similarly to components, they might only support a given subtype (e.g. /mob/living), but the idea is that theoretically, you could apply a specific AI controller to a big a group of different types as possible and it would still work.
These datums handle both the normal movement of mobs, but also their decision making, deciding which actions they will take based on the checks you put into their SelectBehaviors proc.
If behaviors are selected, and the AI is in range, it will try to perform them. It runs all the behaviors it currently has in parallel; allowing for it to for example screech at someone while trying to attack them. As long as it has behaviors running, it will not try to generate new plans, making it not waste CPU when it already has an active goal.
They also hold data for any of the actions they might need to use, such as cooldowns, whether or not they're currently fighting, etcetera this is stored in the blackboard, more information on that below.
Blackboard
The blackboard is an associated list keyed with strings and with values of whatever you want. These store information the mob has such as "Am I attacking someone", "Do I have a weapon". By using an associated list like this, no data needs to be stored on the actions themselves, and you could make actions that work on multiple ai controllers if you so pleased by making the key to use a variable.
AI Behavior
AI behaviors are the actions an AI can take. These can range from "Do an emote" to "Attack this target until he is dead". They are singletons and should contain nothing but static data. Any dynamic data should be stored in the blackboard, to allow different controllers to use the same behaviors.
