Locking STR_SOLDIER behind research is crashing the game.

[The Martian]

(OXCE Version: 7.2 v2021-12-24)

I'm encountering a crash to desktop.

The crash is triggered by starting a new game from the main menu and pressing 'ok' on the difficulty selection screen while my mod is running.

The line of code that appears to be causing the problem is the following:

Code: [Select]

soldiers:
  - type: STR_SOLDIER
    requires: # <----------------------
      - DoesNotExist # <---------------
I'm getting the following error displayed in the linux terminal window I'm running OXCE from after it crashes:
"Floating point exception (core dumped)"


For some reason locking the STR_SOLDIER behind research is causing the 'Float point exception (core dumped)' error.

Is this the wrong way to prohibit the player from purchasing X-Com soldiers from the "Purchase/Recruit" menu?


The openxcom.log file doesn't appear to display any error messages:

For convenience I've attached an example mod with this code to this post:
TestMod Soldiers V0-1.zip

[Meridian]

Is this the wrong way to prohibit the player from purchasing X-Com soldiers from the "Purchase/Recruit" menu?

Yes, this is the wrong way.
You have disabled the soldier type completely, not just for purchase.

The game can't generate any soldiers for the starting base and crashes.

[The Martian]

Thank you very much!

I've removed the starting soldiers and the game is now loading correctly:

Code: [Select]

startingBase:
  randomSoldiers: 0
I have two questions:

(1)
Aside from buying from the "Purchase/Recruit" menu what other actions are blocked by locking a soldier type behind research?

(2)
What is the correct way to lock the STR_SOLDIER type from purchase from the "Purchase/Recruit" menu, should I use the requiresBuyBaseFunc: variable instead?

[Meridian]

1/ everything... and what's not blocked is likely a bug

2/ there are many ways... I would need to know what you want to achieve... if you just want to block purchase, you can set `costBuy: 0`

[The Martian]

if you just want to block purchase, you can set `costBuy: 0`

Thank you that is what I will do.
