[1.1.80] set_request_slot does not allow a count of 0

It seems there may be a small bug in the condition within set_request_slot. I am trying to set spidertron logistic requests to 0 from a mod function, but when I try to run a line like
Code: Select all
spidertron_entity.set_request_slot({name=item.name, count=0}, slot)
I get the following error
Code: Select all
Error while running event spidertron-construction-qol::on_entity_damaged (ID 103)
count must be positive)
stack traceback:
[C]: in function 'set_request_slot'
__spidertron-construction-qol__/control.lua:44: in function 'add_not_requested_items'
__spidertron-construction-qol__/control.lua:56: in function <__spidertron-construction-qol__/control.lua:51>
Since logistic requests can be set to 0 (always trash), shouldn't count have to be
non-negative rather than positive like it is now? Also, I can see many count = 0 for existing logistic requests when logged.
It is also definitely possible I am just doing something wrong lol. Appreciate any help/confirmation!

set_request_slot is for requester chests, which can't auto-trash. It's more of a bug that the function works on non-requesters, though it's probably there for legacy reasons.

-->
Code: Select all
LogisticParameters :: table
Table fields
name :: string?
The item. nil clears the filter.
min :: uint?
max :: uint?
this works because count is actually ignored min is set to 0 and max is infinite because count isn't checked:
Code: Select all
/c
game.player.selected.set_vehicle_logistic_slot(1, {name="wooden-chest", count=0})
this is explicitly 0 and 0:
Code: Select all
/c
game.player.selected.set_vehicle_logistic_slot(1, {name="wooden-chest", min = 0, max = 0})

Agh that was exactly my issue. Your recommendation worked perfectly!
Thank you very much

Thanks for the report. set_request_slot was removed in 2.0 in favor of a unified API for accessing all logistic requests/filters. In the meantime you can use the other functions as mentioned.
