The list does not contain any of the space age building types, but they are buildings and are accepted by https://lua-api.factorio.com/latest/typ ... Flags.html "buildable-type"

I'd like to have access to these properties in runtime stage:

Take a look at https://lua-api.factorio.com/latest/concepts/TechnologyModifier.html
It's missing many of the new things that came with SpaceAge.

I noticed the lack of quality if type == "unlock-quality" and the lack of space_location if type == "unlock-space-location".

There might be more missing ...

I stand corrected, https://lua-api.factorio.com/latest/pro ... ower_input is already available via https://lua-api.factorio.com/latest/cla ... ergy_usage

I must be blind, but I can't find a way to read the fuel filter of ghosts. Would be really handy to know for my planned rate-calculator-like mod.

Please add such a method to LuaEntity or make it return semi-functioning LuaInventory instances

I'd like to have access to this property in runtime stage:
https://lua-api.factorio.com/latest/prototypes/EntityWithHealthPrototype.html#dying_trigger_effect

This is needed to properly calculate where promethium chunks are coming from, because the chunks are not spawning directly. I guess ...

I'd like to have access to this property in runtime stage:
https://lua-api.factorio.com/latest/prototypes/SpacePlatformStarterPackPrototype.html#surface

This is needed when calculating the game progression. I can read the surface from an existing space platform, but I can't know which surface ...

Please note that my request is not for having per-prototype rocket lift weights, but for having the one rocket lift weight available in runtime stage (without resorting to smuggling arbitrary data from data stage). Related, but still completely different.

I'd like to have access to these properties in runtime stage:

I'd like to have access to this property in runtime stage:

I'd like to have access to this property in runtime stage:
https://lua-api.factorio.com/latest/prototypes/ItemPrototype.html#send_to_orbit_mode

this is not the same as having non-empty rocket_launch_products (in py mods there is a byproduct you can only automatically get rid by launching it to ...

I'm trying to get the number of stacks I'm able to put into a (modded) rocket silo

however, LuaEntityPrototype.get_inventory_size(defines.inventory.rocket_silo_rocket) returns nil and get_inventory_size on the rocket_entity_prototype returns nil for every argument I have tried, so I'm out of ...

I try to use a sprite-button for a quality recipe (using the new LuaGuiElement.quality) and have a corresponding tooltip, but the tooltip doesn't work properly

basically this
{ type = "sprite-button", sprite = "recipe/foo", quality = "bar", elem_tooltip = { type = "recipe-with-quality", name = "foo ...

I couldn't find anywhere that uses WorkingVisualisation directly, and from the code I don't think that format is supported. Are you sure about this one?


I can't check that now. I assume that one of the dummy/unknown prototypes had the "wrong" format, which was then ignored as stated by Bilka ...

Thanks a lot for fixing. Regarding OffshorePumpPrototype.fluid_source_offset, was I just blind or is this really missing from runtime stage API?

The left ghost was created using pipette
The right ghost was created using copy&paste (or by undoing a deconstruction)

The issue: In my mod I can't find a way to know which fluid the right ghost will pump
LuaFluidBox.get_locked_fluid(1) returns nil (returns correct fluid ...

Planning tools that work only on data stage (e.g. YAFC) need a way to replicate the weight calculation, but the little information given is not enough to explain what is going on.

Example that might involve some rounding
electronic-circuit
1x iron plate (1000)
3x copper cable (250 each)

these types are documented directly in the only place they are used
