Allow spoil_result to spoil into multiple weighted items

Allow items to spoil into multiple items using a weighted value. And also only allow the item to spoil into one item at a time.
Code: Select all
data.raw["item"]["iron-plate"].spoil_result = {
{
name = "copper-ore",
weight = 1
},
{
name = "iron-ore",
weight = 99
}
}

+1 to that
Currently, you can have multiple "spoil_result" for an item. Each spoil result can have a probability to happen.
But there is no way I'm aware of to make these results mutually exclusive.
Using the scripting option (spoil_to_trigger) can allow to make this possible, but runs into a wall as soon as the item spoils on a belt (because the item disappears first, then the script triggers, so you cannot replace it where it was on the belt).
Plus, scripting it may have a huge performance impact.

Nope, currently you can only specify a single spoil_result, unless you do more complex shenanigans with spoil_to_trigger_result.

That is indeed what I did, I was pretty sure I just tried putting a list of strings, but looking back at the code, I used the insert_item trigger with two items.
Still ! Have the ability to mod multiple results which could be mutually exclusive or not would be nice, in order to be able to spoil in place on a belt simply for instance.

+1, this would be interesting for uranium and nuclear mods modeling half-lives. Imagine that each u-235 has a 50% chance to become whatever u235 decays into, and a 50% chance to stay as u235. That would be so cool.

This is a nice idea, but technically it'd raise a _lot_ of implementation issues. Currently, one stack of items will always spoil into one stack of items - if a stack spoils while an inserter is moving it, or in a container with limited size, or while being carried in a rocket, it'll spoil into exactly one stack replacing the one already there - if one stack of items could spoil into multiple stacks, that would raise a _lot_ of issues. The only sane way I can see this working is if each stack spoils into the same item, which, while averaging out into the same result, would be quite janky.

It wouldn't really be that janky. When combining items into a stack, the spoilage time is averaged, so it's already "janky" by your definition. Making the whole stack spoil into the same item based on the defined weights would be no less jank, and still makes sense.

+ 1, adding a way to spoil into a random result (based on a probability value) would allow for new gameplay possibilities.

Code wise this would be fairly simple to do. Tooltip wise I have zero idea how it would be shown.

A simple suggestion, which I think is clean and clear

I recall raiguard(?) had a WIP implementation of weighted recipe products. See how he's done it?

That's not great, because the weight is divorced from the item.

Well… in fact one of the two kind of blocker issues with that was the tooltip.

I would expect basically the same as seen for e.g. uranium and scrap. No clue how to denote independent chances vs. exactly one though, considering that as it is now is a bit ambiguous.
Edit: checking now, I'm mixing up a couple things (or they've changed); what I was imagining was a percent on top of the icon, although [icon] 12.3% [name] would work too.

Something to consider: if the result is like recipe results, that means you could have several items out of 1 spoiling item? That would mean you could hit a container max and items would need to be able to spill, but I guess that's already taken into account since it can already theoretically spoil into an item with a lower stack size.

The point was to have it weighted such that there would only ever be one outcome. So item A could spoil into item B or item C with a set probability for each totaling 100%, but not both. One of the other suggestions which i like is also having a "spoil to nothing" option where the item just disappears, so you can have item B @ 30%, item C @ 20%, and nothing @ 50%
It is "like recipe results" only in the sense of defining individual "product options" with distinct probabilities

+1, more spoilage ‘types’ is always nice to have and would make some of my ideas way more possible
