Visible bug: with 1 wall ghost queued, all 3 pawns picked the same site; 2 stood idle while 1 built. Same shape would affect chop/mine/haul/etc. Design: Job carries an untyped target_node ref (the tree/rock/build-site/ crop/item/patient/workbench/etc the job is acting on). Job.is_target_taken_ by_other(target, excluding_pawn) does an O(pawns) scan of live job state to ask 'is anyone else already working this?'. Each WorkProvider's find_best_ for() now skips claimed targets in its scan and sets j.target_node before returning. No per-entity claim state, no .claim()/.release() bookkeeping, no save-format change — target_node is intentionally not serialized because pawns re-decide and re-bind naturally after load. Providers updated: construction / chop / mine / plant (harvest path) / hauling (item AND corpse) / cleaning (target is Vector2i tile not Node; field is untyped, doc'd) / doctor / crafting (workbench). Not touched: rest (everyone shares the rest tile, that's fine), eat / sleep (food and beds have their own availability gates; flagged as a followup if multi-pawn food contention surfaces). Verified MCP runtime: fresh boot, 3 pawns picked 3 distinct wall sites (44,28)/(45,28)/(44,27) with distinct target_node refs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

class_name PlantProvider extends WorkProvider
|
|
## WorkProvider for the "plant" work category.
|
|
##
|
|
## Scans World.crops for harvestable (READY) or sowable (TILLED) crops and
|
|
## returns the nearest suitable Job for the requesting pawn.
|
|
##
|
|
## Priority within plant work: harvest > sow.
|
|
## A READY crop is always preferred over a TILLED one — getting food off the
|
|
## plants before it is exposed to weather events matters more than replanting.
|
|
##
|
|
## The returned Job is a two-toil sequence:
|
|
## walk_to(crop.tile) → interact(crop.get_path(), "on_harvest_tick" | "on_sow_tick")
|
|
##
|
|
## The INTERACT toil calls the action method once per sim tick. Both actions
|
|
## complete in a single tick; the done-check in JobRunner._tick_interact fires
|
|
## after the call when is_harvestable() / is_sowable() returns false.
|
|
##
|
|
## Duck-typing note: Crop is referenced without explicit typing to avoid
|
|
## class_name registration-order issues at boot. We rely only on:
|
|
## crop.tile: Vector2i
|
|
## crop.is_harvestable() -> bool
|
|
## crop.is_sowable() -> bool
|
|
## crop.get_path() -> NodePath
|
|
## crop.crop_kind: StringName
|
|
|
|
|
|
func _init() -> void:
|
|
category = &"plant"
|
|
# Above crafting (4) so READY crops get harvested before pawns disappear
|
|
# into plank-crafting loops while wheat rots. Same tier as chop (5).
|
|
priority = 5
|
|
|
|
|
|
## Returns a Job targeting the nearest READY crop, or null when none are ready.
|
|
## `pawn` is duck-typed: must expose .tile (Vector2i).
|
|
##
|
|
## Phase 7 scope: harvest only. Sow work returns null (would loop infinitely
|
|
## with harvest at the same priority — pawns would never craft / cook).
|
|
## Phase 17 will add a separate SowProvider at a lower priority or expose
|
|
## sow as a player-designation flow.
