Vulcanus Artillery Predictor

Factorio 2.x / Space Age mod that lets artillery automatically fire at Vulcanus demolishers (small-demolisher, medium-demolisher, big-demolisher) with a predicted impact point.

How It Works

• Tracks artillery turrets and, optionally, artillery wagons on the configured surface.
• Reads demolishers through the Space Age segmented-unit API.
• Estimates the head movement vector from recent positions and body nodes.
• Predicts where the demolisher will be when the artillery projectile lands.
• Creates the vanilla artillery-projectile at the predicted position.
• Optionally plays lightweight muzzle flash, smoke, and sound near the firing artillery.
• Removes one artillery-shell from the firing artillery inventory unless ammo checks are disabled.
• Processes artillery in small batches to avoid UPS spikes on large Vulcanus bases.

Settings

• Target surface: defaults to vulcanus; use * for all surfaces.
• Scan interval: default 60 ticks.
• Use artillery wagons: enabled by default.
• Require artillery shells: enabled by default.
• Use manual artillery range: disabled by default; the default behavior uses automatic artillery range.
• Prediction multiplier: default 1.0.
• Maximum prediction lead: default 240 ticks.
• Only target generated chunks: enabled by default.
• Maximum shots per scan: default 20; set 0 for no limit.
• Maximum artillery checked per scan: default 64; set 0 for no limit.
• Shot effects: enabled by default; disable for the lowest UPS cost.

Commands

• /vapp-status prints the current cache status.
• /vapp-rebuild rebuilds the artillery cache manually.
