def224667d
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.

# Stationary siege piece: drifts slowly toward the fleet (deliberately no
|
|
# pursuit component - closing distance is incidental, not its purpose) and
|
|
# fires a slow, heavily telegraphed AOE shell on a long cooldown via a
|
|
# standalone ArtilleryShell, so an already-launched shot survives this
|
|
# enemy dying mid-flight, same as EnemyProjectile/Projectile already do.
