Trouble with "requires"

[Align]

I'm trying to make researching the alien grenade prerequire researching Elerium. I've got a savegame where I researched Elerium and have a grenade stored, but it's not showing up as an option.

Use

    dependencies:
      - STR_ELERIUM_115

instead of requires: - from my experience it seems the game only checks the 'requires' if the dependencies are fulfilled. If there aren't any dependencies it will ignore if the 'requires' are fulfilled.

Yes not sure of exact logic, but if there's only one requirement you should use the dependency language instead.

Thanks, that did it. Although now I've got a different problem:

I wanted to make interrogation require autopsy, but there's something weird going on here...

Here are my notes about how it works. I don't remember the exact scenario, but I think get one free is the culprit for weird items showing up in your list that shouldn't be unlocked.

#1) Always have one and only one "requires:" for any UFOPAEDIA entry (cf. XCOMEnforcer below)
#2) Reciprocally, this "requires:" has to trigger one and only one UFOPAEDIA entry (cf. Alloy ammunition below)
#3) If necessary, create a new RESEARCH entry with cost 0 including as dependencies the corresponding "requires:"
#4) getOneFree: seems to need more than one entry, otherwise it unlocks the parent item prematurely it seems.
#5) unlocks can be used to chain several items provided you've got a 0 cost.

I don't think that's it, I haven't used getOneFree so the only entries there would be what vanilla uses, which are all more than one entry.

EDIT: Ah, but the navigator and engineer have getOneFree lists, unlike the soldier which just unlocks. Hmm...

EDIT2: Confirmed, setting getOneFree: [] on the engineer made it unresearchable from start, while navigator (which did not get getOneFree: []) is still bugged. To the bugmobile!

[jackstraw2323]

If you just want to chain one project to the next for free, I.e. Item A gets you item B, use unlocks and set the requirements for time etc on B to 0.

I'd prefer not to touch the getOneFree lists, so I'll wait and see if it gets fixed.

Meanwhile, I've been trying to figure out when to use requires:

Code: [Select]

  - name: STR_TESTME1
    cost: 1
  - name: STR_TESTME2
    cost: 1
  - name: STR_TESTME_HASREQ
    cost: 1
    requires:
      - STR_TESTME1
  - name: STR_TESTME_HASDEP
    cost: 1
    dependencies:
      - STR_TESTME1
  - name: STR_TESTME_HASREQDEP
    cost: 1
    requires:
      - STR_TESTME1
    dependencies:
      - STR_TESTME2After researching TESTME1, TESTME_HASDEP becomes available, but even after researching that and TESTME2, I can't research TESTME_HASREQ or _HASREQDEP. So is it only usable for cost 0 entries? Like STR_COMMANDER_PLUS in the vanilla ruleset.

Try to use "unlocks" keyword.

Code: [Select]

- name: STR_TESTME1
    cost: 1
    unlocks:
        - STR_TESTME_HASREQ
        - STR_TESTME_HASREQDEP
  - name: STR_TESTME2
    cost: 1
  - name: STR_TESTME_HASREQ
    cost: 1
    requires:
      - STR_TESTME1
  - name: STR_TESTME_HASDEP
    cost: 1
    dependencies:
      - STR_TESTME1
  - name: STR_TESTME_HASREQDEP
    cost: 1
    requires:
      - STR_TESTME1
    dependencies:
      - STR_TESTME2

Code: [Select]

  - name: STR_RESEARCH_PROJECT_1
    dependencies:
      - STR_DEPENDENCY_1
      - STR_DEPENDENCY_2
      - STR_DEPENDENCY_3
      - STR_RESEARCH_PROJECT_1_UNLOCK
  - name: STR_RESEARCH_PROJECT_1_UNLOCK
    requires:
      - STR_DEPENDENCY_1
      - STR_DEPENDENCY_2
      - STR_DEPENDENCY_3
    dependencies:
      - STR_ALIVE_ALIEN
  - name: STR_RESEARCH_PROJECT_2
    dependencies:
      - STR_RESEARCH_PROJECT_1
      - STR_RESEARCH_PROJECT_2_UNLOCK
  - name: STR_RESEARCH_PROJECT_2_UNLOCK
    requires:
      - STR_RESEARCH_PROJECT_1
    dependencies:
      - STR_ALIVE_ALIEN
  - name: STR_ALIVE_ALIEN
    unlocks:
      - STR_RESEARCH_PROJECT_1_UNLOCK
      - STR_RESEARCH_PROJECT_2_UNLOCK

This should work
Explanation:
RESEARCH_PROJECT_1 will show up in the Research popup, after DEPENDENCY 1-3 are fullfilled and STR_ALIVE_ALIEN is researched. STR_ALIVE_ALIEN unlocks the last DEPENDENCY -> STR_RESEARCH_PROJECT_1_UNLOCK. Which will only be considered for unlocking after DEPENDENCY 1-3 have been researched.
After this you will see the STR_RESEARCH_PROJECT_1 in the research popup.

STR_RESEARCH_PROJECT_2 will be avaible after another STR_ALIVE_ALIEN has been researched, STR_RESEARCH_PROJECT_2_UNLOCK will not even be considered to be unlocked until STR_RESEARCH_PROJECT_1 is researched and avaible.

Hope this helps

This should work

It didn't... but should work now in the latest nightly.
