[Rseding91] [2.0.12] Stale space platform ghosts visible in map view (MR)

[Matrix_V]

In the attached save file, look at the space platform Defiance. On the main view while zoomed out, and on the map in the top right corner while zoomed in, there are two areas of construction ghosts that remain visible: a large pinkish/purplish rectangular region left of the platform hub, and a smaller, irregular grey region to the right of the hub. Both have been present for at least several hours.

Blueprinting from the platform out to these stale ghosts will correctly update the map. Destructing this new construction will then leave it as a stale ghost on the map.

Thanks for the report. This was deemed an acceptable compromise to allow building ghosts in fog-of-war area. When built, they will update the chart, but when removed, they do not - unless you have radar coverage in the area. For space platforms you have to physically build the platform to that area for the auto-radar-coverage to account for it.

If anyone else comes here looking for a solution, if the platform is open in remote view, you can just run this command:

Code: Select all

/c game.player.force.rechart(game.player.surface)

I'm curious though if there's a way to increase the "radar" range of platforms so this doesn't keep happening? (Why do platforms even have a "fog of war"?)

EDIT: I made a mod (https://mods.factorio.com/mod/platform-map-update) that recharts automatically for you when switching between surface in remote view

Why do platforms even have a "fog of war"?

All surfaces have "fog of war" because to not have it means constant re-scanning of chunks to update the map images which has a measurable performance overhead.

Posting a picture for easier conversation. The red arrow points to the entities that don't exist. What I don't know if this is the exact issue OP is mentioning, as you can see in my picture, it is close to my ship, so it's not in the fog of war.

[Muche]

Yeah. Your rightmost thruster looks to be right at the edge of a chunk, so it should see and refresh that chunk to the right with platform ghosts of past.
(Unless I counted pixels wrong and there is one extra tile of empty space next to the thruster still within the same chunk.)

FYI, I've now made my mod https://mods.factorio.com/mod/platform-map-update update the map as often as necessary (i.e. whenever an entity/tile/ghost is created/destroyed on the platform), and so far it hasn't caused me any performance issue, but I haven't been playing with any large platforms.
