How to delete a logistic group?

[Pi-C]

We can easily define logistic groups:

Code: Select all

/c p = game.player
    pos = p.position
    v = p.surface.create_entity{name = "car", force = p.force, position = {pos.x + 5, pos.y}}
    requester = v.get_logistic_point(defines.logistic_member_index.car_requester)
    requester.sections[1].set_slot(1, {value = {type = "item", name = "iron-plate", quality = "normal"}, min = 10})
    requester.sections[1].group = "test"
 

If you open the new car, you can edit/remove the group name from the section and you also get a button to delete the logistic group:

I want to delete groups that have been created by my mod, but I don't see how to do this by script. Is there really no way to do this?

Maybe set group to an empty string

Maybe set group to an empty string

That wouldn't work. Run the command from my first post, then enter the following:

Code: Select all

/c requester.sections[1].group = ""

This will remove the group name from the section, but the group is still available in the "Change logistic group" GUI:

The problem is this: We can create a LuaLogisticSection manually or by script. We can create a group manually (enter a new name into the "Change logistic group" GUI) or by script (set LuaLogisticSection::group to a string that hasn't been used yet), and we can change the group name of a section manually (select one of the existing names from "Change logistic group" GUI) and by script (set LuaLogisticSection::group to an existing name). However, once a group has been created, the only way to delete the group that I've found is to manually remove it using the "Delete logistic group" button from the GUI.
