ai_controller

Vars
ai_movement	Reference to the movement datum we use. Is a type on initialize but becomes a ref afterwards.
ai_status	Current status of AI (OFF/ON/IDLE)
ai_traits	Bitfield of traits for this AI to handle extra behavior
behavior_args	Stored arguments for behaviors given during their initial creation
behavior_cooldowns	Current actions and their respective last time ran as an assoc list.
blackboard	This is a list of variables the AI uses and can be mutated by actions. When an action is performed you pass this list and any relevant keys for the variables it can mutate.
continue_processing_when_client	Can the AI remain in control if there is a client?
current_behaviors	Current actions being performed by the AI.
current_movement_target	Current movement target of the AI, generally set by decision making.
failed_planning_cooldown	Cooldown for new plans, to prevent AI from going nuts if it can't think of new plans and looping on end
max_target_distance	distance to give up on target
move_delay	Delay between atom movements, if this is not a multiplication of the delay in
movement_cooldown	Cooldown until next movement
movement_delay	Delay between movements. This is on the controller so we can keep the movement datum singleton
movement_path	A list for the path we're currently following, if we're using JPS pathing
pathing_attempts	Tracks recent pathing attempts, if we fail too many in a row we fail our current plans.
paused_until	AI paused time
pawn	The atom this controller is controlling
planning_subtrees	All subtrees this AI has available, will run them in order, so make sure they're in the order you want them to run. On initialization of this type, it will start as a typepath(s) and get converted to references of ai_subtrees found in SSai_controllers when init_subtrees() is called
repath_cooldown	Cooldown for JPS movement, how often we're allowed to try making a new path
Procs
MoveTo	Are we close enough to engage? Move somewhere using dumb movement (byond base)
PerformIdleBehavior	Perform some dumb idle behavior.
PossessPawn	Proc to move from one pawn to another, this will destroy the target's existing controller.
SelectBehaviors	This is where you decide what actions are taken by the AI.
TryPossessPawn	Abstract proc for initializing the pawn to the new controller
UnpossessPawn	Proc for deinitializing the pawn to the old controller
able_to_run	Returns TRUE if the ai controller can actually run at the moment.
change_ai_movement_type	Overrides the current ai_movement of this controller with a new one
get_access	Use this proc to define how your controller defines what access the pawn has for the sake of pathfinding, likely pointing to whatever ID slot is relevant
init_subtrees	Loops over the subtrees in planning_subtrees and looks at the ai_controllers to grab a reference, ENSURE planning_subtrees ARE TYPEPATHS AND NOT INSTANCES/REFERENCES BEFORE EXECUTING THIS
process	Generates a plan and see if our existing one is still valid.
replace_planning_subtrees	Completely replaces the planning_subtrees with a new set based on argument provided, list provided must contain specifically typepaths
set_ai_status	This proc handles changing ai status, and starts/stops processing if required.
