In short trying to get the ammo-type from an ammo slot

create a tank and select it
/c inv = game.player.selected.get_inventory(defines.inventory.car_ammo); game.player.print(tostring(inv.has_filters())) -- returns true
/c inv = game.player.selected.get_inventory(defines.inventory.car_ammo); game.player.print(tostring(inv.get_filter(1))) -- returns nil

my assumption is that because it is type and not an item it is returning nil and if this is the case can it be changed to return type if item doesn't exist? or add inventory:get_ammo_filter to return ammo type?

Those 2 functions do 2 completely different things and what you describe is perfectly normal.

An inventory can support filters (thus has_filters() returns true) and have no filters set (thus get_filter(..) returns nil).

Well that explains that.

Any chance for an inventory:get_ammo_category(slot) to return string ammo-type?

hm... maybe a better name for the function? like support_filters()?

or is_filterable()
