Hi, is possible add to the event on_player_placed_equipment a new argument like "raised_by_a_mod" or a sort of, that with a boolean value, will inform the callback if the event was raised from a mod using the function LuaEquipmentGrid.put(...) ?

As always, thank you for the attention.

They added two new events on_equipment_inserted and on_equipment_removed. However you still can't isolate when equipment was inserted/removed by script, since the new events also fire when it was done by the player. In case there is a way to do it, I would be interested in that.

Afaik the player can only insert into grids they have an open gui of. So you should be able to isolate the cases that are definetly by script, leaving a mangled rest of player-or-script situations. (Based on basic logic without having had a look at the events.)

A better and unambiguous logic would be to check if both events fire. If yes, then placed by a player (and you get which from the player event). The effectiveness of this depends on the event order though.

Perhaps an optional player field in on_equipment_inserted, if nil, it wasn't a player?

Do note that an inserter can... insert equipment into a grid under the correct conditions.

Why does it matter if it was done by a player or not?

Uuuh, how?

Edit: To actually address the topic:

I suspect that one reason to want to know if the event was raised by a script is to avoid two scripts duelling over what precisely should be in the equipment grid or not.

I assume that that's a large part of why the script_raised events exist.

At least in 0.18, an item that is both a fuel item and equipment will be happily inserted by an inserter into a locomotive with an equipment grid's equipment grid.*

I don't know if it works in the general case of equipment that isn't also a fuel item, or if it still works that way in 1.1, but it was definitely a "Huh, that's weird" moment.
