Ghost Scanner
A combinator that outputs the items needed to build construction ghosts as circuit-network signals.
Wire it to a requester chest or train logic and let your factory supply its own construction sites.
Unlocked by Advanced combinators. Recipe: 5 copper cable, 5 electronic circuits.
Scan modes
Click the scanner to choose a mode:
- Normal: scans the logistic network the scanner is placed in.
- Area: scans a custom rectangle. Press Select area to get a selection tool, then left-click and drag on the map. The area is highlighted while you hover over the scanner.
Switching the scanner off clears its output and pauses scanning.
What gets reported
Each scanner can toggle these individually:
- Entity ghosts
- Tile ghosts (concrete, landfill, …)
- Modules requested by entity ghosts
- Modules requested by already-built entities (item-request proxies)
- Upgrades (items needed to fulfil upgrade markers)
- Cliff explosives for cliffs marked for deconstruction
Settings
Map settings:
| Setting | Default | Description |
|---|---|---|
| Scanned cells per tick | 5 | Logistic cells (or Area regions) scanned each tick. Lower improves UPS. |
| Logistic network update interval (ticks) | 180 | Minimum ticks between full re-scans of each scanner. |
| Scan tick delay | 5 | Minimum tick spacing between scan work slices. |
| Per-scanner result limit | 1000 | Ghosts found per scan pass; 0 removes the limit. Lower improves UPS. |
| Area mode maximum side length | 512 | Largest allowed Area selection, in tiles. |
| Show hidden items | off | Also report hidden items. |
| Invert output | off | Output negative values, useful for request combinators. |
| Round to stacks | off | Round counts up (down when inverted) to full stacks. |
Per-player settings: border and fill color of the Area overlay.
Compatibility
This mod is based on GhostScanner4 but has been improved and cannot be enabled together with
- GhostScanner
- GhostScanner2
- GhostScanner4
- ghost-combinator - may works, but shouldn't be used together
- ghost-reader - may works, but shouldn't be used together. Also, this mod has pretty poor performance, so I wouldn't recommend it at all.
