I was playing the second campaign and was wondering how I could research electronics. ... because I could reach it in the technology tree.
The way was: Turrets -> Laser turrets -> laser -> electronics-1. Could see it, but could not research.
After a while it was clear to me, that it's turned off, because it's wanted in this campaign. But for me this wasn't obvious. I played about an hour until I understand, that there will be no change, no matter how much I research. I hope & think a new version will show the tree like in https://forums.factorio.com/wiki/index.php/Research - and unresearchable items aren't shown.
But I want to suggest something here. How would it be to create a buffer of research items, which are researched in some order, because in the beginning you will normally decide quick which way of research you want to go and don't want to be disturbed all the time.
The list has no fixed max-number of entries, like in many other games. The number of researches you can add to this list depends on, how long each research will take. If you know EVE-Online you will know, what I mean, but if not. But I explain it here in detail.
The list has a "memory" and remember the next researches for up to 50 research-points. So you can research iron-working (10 points), then turrets (also 10), then chemistry (40). Then the list is full, because that will take 60 research points. But you started at 20 points, so the start of the research can be stored inside the memory. With this "trick" it isn't possible to research the same amount of items in another order: First chemistry, then iron-working and then the list is full and no item can be added anymore.
I tried to show this:
Code: Select all
1 2 3 4 5
12345678901234567890123456789012345678901234567890
Example 1:
____________________________________________________________
iron-work| turrets | chemistry |
Example 2:
_________________________________________________
chemistry |iron-work| < no space left but you can add the next item, when 1 point of chemistry was researched!
