EnemyArtilleryComponent is a stationary siege piece (slow drift toward
the fleet, deliberately no pursuit component) that fires at the fleet
centroid on a long cooldown via a standalone ArtilleryShell -
telegraph ring (~1.8s, growing radius plus a filling countdown arc) ->
slow visible travel -> AOE explosion via Ship.take_damage() on every
player_ships node inside, same all-or-nothing shield absorption as
every other damage source. The shell is independent of the enemy that
fired it (added to the tree root, like EnemyProjectile/Projectile) so
the shooter dying mid-flight doesn't cancel an already-telegraphed
shot, and the impact point is fixed at fire time - never re-aimed at
where the fleet moves to afterward.
Part of the #40 conquest-mechanic breakdown.
EnemyStandoffComponent holds a preferred distance from the nearest
player ship instead of ramming (advance beyond it, retreat inside
retreat_range_factor of it, drift laterally in the comfortable band
between) - never paired with a pursuit component. EnemyRangedWeaponComponent
mirrors VesselWeaponComponent for an enemy: fires an EnemyProjectile
aimed at the target's CURRENT position rather than led, so a moving
ship can dodge it (projectile_speed 260 vs the interceptor's 460
max_speed). Registered in EnemyDefinitions so it's placeable from a
planet setup by enemy_id.
test_sniper_enemy.gd went through a few iterations to get its own
timing right: physics ticks can run ahead of a SceneTree test's own
_process() clock under this device's load, so the cooldown-violation
check reads the component's own fire_timer directly (a rising value
means it refired) instead of comparing projectile counts against a
wall-clock wait, and manually repositioned ships need their
move_target re-pinned or Ship's own steering silently drives them back
to the stale target.
Part of the #40 conquest-mechanic breakdown.
Enemy.gd now resolves stats/hull/color from EnemyDefinition resources
and composes behaviour from capability components (EnemyPursuitComponent
holds today's chase-the-nearest-ship logic), the same shape Ship.gd
already uses for vessels. Fleet lookups go through a "player_fleet"
group instead of a hardcoded ../Fleet sibling path, so an enemy parented
anywhere (e.g. under a planet surface's SurfaceFeatures) still finds it.
Also closes a real gap: enemies previously had no way to damage the
fleet at range at all (Ship only reacted to physical contact,
Projectile.gd was player-only). Ship.take_damage() is now a proper
entry point - contact damage routes through it unchanged - and
EnemyProjectile lets an enemy component fire at player_ships. Both
ranged enemy archetypes in #45/#46 build on this.
