[0.17.79] Placing train signal over its ghost does not adopt its direction

[Blacky007]

I was building with ghost planer and building the signal manualy
but in this case the planer preselected the wrong signal position that hasn't even be planed by ghost.

is this as designet or wrong order of preselection?

plz give blueprint string

BP doesn't matter

build a strait rail with a signal - create a ghost siderail with the two signals like in picture 1
try to build the chainsignal by hand.

[Squelch]

I believe this is by design.

The chain signal that the arrow points to is in a location that it has two valid orientations. If you look closely, its orientation shows it will connect to the ghosted branch, and not the existing track. The ghost track does not yet have a direction defined, so is therefore treated as bidirectional - the other ghost rail signal is not treated as a valid signal yet, so therefore has not constrained the direction of travel.

This happens often where two tracks intersect at an angle. Especially if one is bidirectional, or not yet constrained by existing signals. Use the rotate button to force the chain signal to attach to the correct track in this case.

Can you confirm, that what you consider the bug is, that when attempting to place the non ghost signal entity on the ghost signal its direction is not the same as the ghosts direction?

yes it is not the ghost direktion when you try to build the Signal - it creates a signal on the ghost track from the south-west - you need to choose the second option with rotating the signal

[Blacky007]

the same bug happens on rail tracks that are crossing under 90 degres north-south // east-west

Copy blueprint

[Klonan]

I don't really see a major problem here

I think this is a general feature of "Manually you can place stuff as you wish and it generally ignores blueprints in the location". The same applies to rails and signals... so you have to rotate them appropriately before placing them.

Overall this behaviour is more advantegous than disadvantegous

I think the default rotation should be the one of the ghost if there is one though.

This report has been on my mind since it was posted, and only now do I see how there might be some confusion in assuming that the ghost's rotation would be assumed. Therefore, I feel it might be prudent to clarify how the process works for anyone else having a similar problem with manual building over ghosts and blueprints.

If the item in hand is taken directly from your inventory or item shortcut used, and placed over the ghosted entity. it will adopt the default rotation for that item. However, if the dropper/picker/pipette (Q by default on English layout KB's) is used to bring the item to hand while hovering over the ghost, only then will the item will adopt the ghost's rotation.

But this is also exactly the behavior of inserters, miners, refineries and chemplants. Why would anyone assume that especially rail signals behave differently in that regard?

It seems to be the most plausible reason for the bug report.

@Blacky007 can probably confirm or otherwise if this is the case.

[Blacky007]

why is this moved to Won't fix?
the signal is taking the orientation from the ghost rail on the opposide direction where no signal is ghostprinted.
this signals makes NO SENCE in this situation!

for me this is clearly a bug that need to be fixed

use Ghost Placer Express mod, problem solved.
