Spidertron Hunter

Spidertron Hunter

> Give your Spidertrons a mission.

Spidertron Hunter transforms idle Spidertrons into autonomous combat units that hunt enemy bases, scout unexplored terrain, and return home to repair and restock—all while using vanilla Spidertron autopilot.

Designed to feel like a natural extension of vanilla gameplay, the focus is automation, not stronger Spidertrons.

Hunter Mode

Patrol
→ Search
→ Move
→ Attack
→ Linger
→ Return Home
→ Restock
→ Re-engage (optional)
→ Patrol

Hunters automatically:

• Search for nearby enemy bases
• Navigate around lakes using vanilla pathfinding
• Fight using configurable combat styles
• Avoid acid puddles
• Retreat when hull or shields fall below configurable thresholds
• Return home when ammo drops to Restock ammo % of the logistic request (default 20)
• Return home for repairs and logistics
• Optionally return to the previous battle and continue hunting

Hunter remote

Right-click issues a straight vanilla autopilot path (as before).

Ctrl+right-click uses Hunter's built-in lake-aware pathfinder (no other spider mods required; works with AI on or off): ground clicks travel then resume hunting when AI is enabled; enemy clicks path then engage.

---

Scout Mode

Explore
→ Chart Fog
→ Discover Enemies
→ Return Home
→ Restock
→ Resume

Scouts are dedicated exploration units.

They:

• Never engage enemies
• Chart unexplored terrain
• Discover enemy bases for Hunters
• Maintain standoff distance from biters
• Return home automatically

Scout mode requires:

• No ammunition
• No Personal Laser Defense equipment

If a Scout begins zig-zagging, it is usually avoiding nearby enemies. Send a Hunter group to clear the area.

---

Fleet Manager

Open with Ctrl+Shift+M.

Spidertrons are grouped by entity label (or prototype name if unlabeled). Each group card shows active Hunter/Scout counts (e.g. 2H, 1S).

Each group provides:

• Follow — Group follows the player
• Remote — Select the group with a Spidertron Remote
• Home — Return home (Ctrl-click sets current position as Home)
• Show Group — Jump to the group using remote view
• Settings — Open one Spidertron's settings
• AI Toggle — Enable Off as Hunter, or disable if all are on. Ctrl-click enables Off members as Scout (armed spiders are refused)
• Pin — Keep the window open while using remotes or Spidertron GUIs

---

Scout Controls

Vanilla Spidertron Remote

Click the map to choose an exploration focus.

This clears queued waypoints and begins autonomous exploration around the selected area.

Ctrl+right-click uses a lake-aware path when setting focus.

Scout Remote

Use Alt+Shift+A to place Scout waypoints.

Waypoints are completed in order before autonomous exploration resumes.

Ctrl+right-click appends a waypoint with lake-aware pathing.

Available exploration algorithms:

• Frontier
• Lawnmower
• Spiral

Why Spidertron Hunter?

Spidertron Hunter extends vanilla Spidertrons instead of replacing them.

Spidertrons still require:

• Ammunition
• Equipment
• Power
• Repairs
• Logistics

The AI simply gives idle Spidertrons useful jobs without changing their underlying balance.

Compatibility

Requires Factorio 2.1. Going forward, development and releases target 2.1 only (Factorio 2.0 is not supported).

Optional compatibility is included for:

• Spidertron Patrols
• Spidertron Enhancements
• Space Age

Lake-aware Ctrl+right-click is built into Hunter (own pathfinder and building-collision data). You do not need Enhancements or Patrols for pathing.

When Hunter AI is enabled alongside Spidertron Patrols, patrol control is temporarily switched to manual so both mods don't compete for Spidertron autopilot. Previous behavior is restored when Hunter AI is disabled.
