While you could achieve similar effects, you couldn't achieve the exact same ones - say you have amount_min=4, amount_max=8, and ignored_by_quality=6. If you produce <= 6, you would have no quality; conversely, if you have > 6, you could have quality. There isn't any other way to achieve this ...

One person suggested making a ItemProductPrototype::ignored_by_quality member that is an integer, and would mean that specific product could produce both the same quality and a different quality in one cycle of the recipe.

Seems unnecessary to me. It only concerns the products and you can have ...

It is obvious from the API.

Of course these would need to respect what quality levels are supported (and possibly unlocked) so a normal quality recipe bumped by -1 would result in normal items, and a legendary recipe bumped +1 would result in legendary items.

Or those recipe variants just aren't available. To reduce ...

On the second thought, just checking that no character shares the crafting category with the recipe might be enough.

I am not contradicting myself. There is some magic inside of the assembler logic since it tries to select recipes using item signals, however with barreling specifically there is no such magic due to catalysts involved and so we require recipe signals to be present because assembler with set ...

There is no item/recipe black magic here. Barreling recipes and unbarreling recipes cannot be selected by the item signal because those recipes do not create new items (due to catalysts), and as such the only way to select correct recipes is by sending a recipe signal. If those recipe signals ...

So the item/recipe merging black magic strikes again. Imagine if instead it was sanely explicitly specified in the prototype.

The event documentation already specifies the player_index as optional, if that was missed - would an extra comment about one of the ways it might not be provided be useful?

I’ve found when comments like that exist, people take them to mean “this is the *only* time this happens” when that isn’t ...

Can you provide any more details about your application and why an invisible container entity with interactions disabled is insufficient? A script could cause the player to open the container's gui even if the container itself is not clickable. The contents can be stored in the invisible container ...

"Note: if this starts the crafting process, result_quality will not be set automatically and will default to normal, even for quality recipes."

But it's pretty stupid that a quality recipe has no inherent quality to it.

Answer: No, because helpers.is_valid_sprite_path("__base__/../space-age/thumbnail.png") is not usable in prototype stage.
and even it does, you probablly cannot use it for detection purpose at all.

To be fair, being able to do that's a sandbox violation and should be fixed ( or made properly a ...

In that case be more particular about where you put your recipes? You can always make a biochamber only and chemplant only one, and I think most modded recipes won't run into that issue. I believe that your problem here is trying to keep the one recipe instead of just swapping it between the two ...

At most what i could make is a quality_behavior on item product prototype with 3 options: "default" (for current behavior), "no_bump" for product not affected by quality but preserving input quality, and "set_normal" that would always give normal quality product regardless of ingredients quality ...

I don't have a use case, it's just something (or lack thereof) I see every so often in mods. Recently I've been reminded of Discovery Tree.

With what you have outlined, the only resort aside from your idea seems to be involving the player. Like Discovery Tree does, include a way to prepare for mod ...

I second this request. I think it would be most easily achompplished with a single lua file removal_migration.lua or something. The code in there would be like a migration script except it couldn't have any imports which would allow the file to run without the mod as long as it was saved into the ...

Do note that it's the spider units (e.g. pentapods) that have radar_range. Spider vehicles have one and only chunk_exploration_radius, which is exactly how the vanilla defines it in its prototype code. There is no overlap.
