Am I reading the docs wrong, or just being stumped by a documentation note error?

I think you're reading it wrong. It means it's been added since 2.0.77, so that's the last version without it.

Now that you can set an override_pollution_type , mods that handle pollution in special ways might need to be aware of when it changes.

I specifically need it because I keep track specific entities and whether or not their chunk exceeds their working pollution range. The loop for this is pretty ...

Specifically something like


-- 50/50 Always returns an item, with a chance of it being iron or copper plate
results =
{
{type = "item", name = "iron-plate", amount = 1, shared_probability = {min = 0, max = 0.5}},
{type = "item", name = "copper-plate", amount = 1, shared_probability = {min = 0 ...

TL;DR
Highlighting the reactors that are connected as neighbours during and after placement would increase legibility of what qualifies for the neighbour bonus.

What?
Entities that would connect because of NeighbourConnectable should be highlighted when you select one. I imagine it would work ...

The *tag* part is already part of the api: https://lua-api.factorio.com/latest/classes/LuaPlayer.html#tag
Since it's just a string, you can use rich text to make it colored

I do still want some way to intercept and modify chat messages so I can prefix things like a timestamp on all messages, and ...

I can see it being a probelm to specify the slot though, since LuaItemStack doesn't always point at an inventory.


I always imagined it being an inventory and slot index pair. Didn't even consider the idea of using LuaItemStacks.

I also was considering fluidbox slots.. We know there's an ...

Would it be possible to add some way to render these psuedo-filters manually, like EmptySlotInfo per slot?


Ditto. A solution to be able to recreate this logic manually would be sufficient, and might in fact be a better resolution.

I can imagine it being used alongside someone's manual handling ...

Looks like I forgot that EmptySlotInfo already supports caption and text (2 of the 3 components)

Since my use case is empty inventory slots, It makes sense to just add it there and hard-restrict it to items.

Somewhat related to https://forums.factorio.com/77339 but smaller in scope, I want the ability to recreate the tooltip style used by furnace inputs, burner inputs, module slots, and maybe more.

I can see it either being an elem_tooltip type or a sister field, but it looks ...

The engine uses faded (desaturated?) sprites for filter slots, there does not seem to be any way for us to do the same for our sprites or sprite-buttons.
If the engine enables/disables it instead of applying some percentage value, I don't mind if it's is_faded instead.

Even if my requests (https ...

This is a far fetched request, I understand. I'll give you my use case because I can see ways it'd be implemented with the currently existed Inventory element.

I'm trying to recreate the crafter gui (I fear the point where I start considering the remote GUI) because I have a compound entity that ...

Standard filter slots work fine, but when pointing at an inventory that's filtered in an alternative way (eg crafter input) it does not appear. I request there be some mechanism to support these filters, which I understand might be difficult depending on current code structure. Alongside this ...

Implemented in 2.1.7

Also seems like 131526 was a duplicate of this one

In my process of looking for duplicate requests about expanding the functionality of our new Inventory LuaGuiElement, I found this request.
This can be moved into implemented with 2.1.7

From protocol, since his account isn't working right now: Upon further investigation, it seems that the offsets don't function properly when the opposite axis for the other direction is 0 or nil, i.e. the vertical y offset will not function when the horizontal x offset is 0. I haven't checked but ...

I'm making a compound entity so I can pretend an entity has multiple energy sources. To make the internal burners accessible I'm making specific input ports out of loaders, which means they'll inevitably overlap with the main entity. There might be a specific way to get them to link to the ...

I am here to ask for an auxiliary page to list the required prototypes, eg: the 'out-of-map' tile. I feel there should be sections for each grouping of required prototypes; "core" for always required prototypes, "space_travel" for the prototypes required with the "space_travel" feature flag, etc ...

It seem difficult to mod without redoing the whole system, so i thought i would just suggest a "clicking" sound.


I don't think it would be. At a minimum, doing a linked control might be enough.
If not, you can play a sound if it and on_player_music_changed happen in quick succession.

That sounds like you should be defining the entity . Since the trigger fires from a tile, there is no entity to use by default.

The failure to create pollution when it fails to find an entity does sound like a bug, which you should be reporting over in Bug Reports . Although I can see an argument ...
