Follow-up to https://forums.factorio.com/viewtopic.php?p=673493 - thank you for considering this nitpick in the first place :) You guys are awesome

I probably should've included the -with-quality elems alongside original post, but yeah - they seem to not respect hidden filter, while the rest do ...

LuaGuiElement#elem_filters in examples mentions the hidden filter:


-- Then, there are some types of filters that work on a specific kind of attribute. The following will configure a

button.elem ...

Yeah I've never followed up with this. I tried flipping the ingredient order now and it works in 2.0.52, it seems to be a bug fixed since at least 2.0.48

1. Create a choose-elem-button with any elem_type, but starting disabled
2. Enable it later. If running Space Age, assign any elem_filters to it, otherwise it will work as expected
3. Perform selection
4. Expect its graphics to return to normal. Instead it's as if it's still being hovered over ...

Thank you, genuinely! You lot are the best. This can be considered implemented in my opinion

Curious, would this mean that any one of the agricultural towers may mine that plant, or does it imply something else?

There is no way to infer the bounds of an agricultural tower at runtime.
Exposing AgriculturalTowerPrototype#radius and AgriculturalTowerPrototype#growth_grid_tile_size (EDIT: already is, didn't notice) to LuaEntityPrototype is enough.

There is LuaEntityPrototype#radius already but it's related to ...

When an agricultural tower is hovered over, the plants that it seeded are shown:

It would be nice to have that exposed in runtime API, say with this signature:

[AgriculturalTower only] LuaEntity ::get_owned_plants() -> array[ LuaEntity ]

I imagine the game engine doesn ...

There is LuaEntity#get_cargo_bays for relating space platform hub / cargo landing pad to its cargo bays, but no clean way to go in reverse.

Workaround for when connected to platform hub is cargo bay entity's .surface.platform.hub . When it's connected to landing pad, mod has to either keep track of ...

Imagine if recycling recipes required a fluid. Say you specify the fluid as 2nd ingredient:

data:extend({{

ingredients = {
{type = "item", name = item_name, amount = 1},
{type = "fluid", name = "promethium-emulsion", amount = fluid_requirement}
