Casper: Ghost Tracking
Pasted a huge blueprint and can't find the last few unbuilt ghosts? Casper finds them for you.
Drag over a build, and every unbuilt ghost inside gets highlighted plus a live counter of what's left. As things get built they tick off, and when everything is done the counter disappears.
Casper: track ghosts
Get it from the green ghost button in the shortcut bar, or press Shift + Alt + G.
| With Casper in hand | What it does |
|---|---|
| Drag | Start tracking every unbuilt ghost in the box (replaces your current job) |
| Shift + drag | Add more ghosts to your current job |
| Alt + click | Cancel the job |
- Green brackets mark each tracked ghost, in the same style as copy-paste, so stragglers stand out even in dense builds.
- Belts and pipes get one clean green outline around each connected group. Bends and corners are followed, so a long belt line reads as one shape instead of dozens of brackets. When a piece in the middle gets built, the outline splits on its own.
- Snapshot: only the ghosts inside the box when you drag are tracked. Ghosts placed later aren't added.
- Removed ghosts (deconstructed, cancelled or replaced) quietly drop out of the count.
Live preview while dragging
While you drag, ghosts inside the box light up and the bar fills in with exactly what will be tracked, like a blueprint's contents. Shift-drag shows your current job plus the new ghosts, so you know the result before you let go.
The counter bar
- Sits at the top of the screen, next to your mod buttons, and lists every remaining item with its count.
- Grows and shrinks with the job, 10 icons per row, adding rows as needed.
- Click the ghost icon to fold the bar down to just the icon, and click again to unfold. Hover the icon to see how many ghosts are left.
Find the stragglers
- Hover an item icon: a green arrow appears next to your character, with a dashed path leading to the nearest unbuilt ghost of that type and a ring around it.
- Click an item icon: the guide stays pinned (the icon stays pressed in) and re-aims as you move and as ghosts get built. Click again to unpin. It clears itself once that type is done.
- The path also shows on the map, so you can track down ghosts on the far side of your base.
The Exorcist: remove things from tracking
Don't care about those 200 lamps right now? Exorcise them.
Get it from the red disintegrating-ghost button, or press Shift + Alt + E.
| With the Exorcist in hand | What it does |
|---|---|
| Click a ghost or building | Pick that type |
| Shift + click | Un-pick that type |
| Shift + drag | Pick every type inside the box |
| Drag | Remove tracked ghosts of the picked types inside the box |
- Picked types show in a red strip under the Casper bar while you hold the Exorcist.
- You can pick from finished buildings too: click a lamp you already built to pick lamps.
- Picks ignore quality: picking a lamp covers lamps of every quality.
- Drag as many times as you like. Picks reset when you put the tool away.
- Exorcised ghosts stay in the world. Casper just stops tracking them.
Works on the map
- Use both tools in map view, even outside a radar's live range.
- Tracked ghosts show as green marks on the map, and belt and pipe groups are filled in, so you can see what's left across your whole base.
- Sectors that have never been scanned are ignored.
Good to know
- Per-player: each player has their own job, and only you see your highlights, marks, guide and bar.
- One job at a time: a new drag replaces the old job.
- Leaving the planet cancels the job. Looking at other planets in remote view does not.
- Performance: robots building fast won't spam updates, and big drags stay cheap.
- Hotkeys can be changed in Settings → Controls.
Requirements
- Factorio 2.1.22 or newer
- No other mods needed. Works with or without Space Age.
