A common mistake I've been seeing for new modders, is that they either use the global table right away (naively assuming it's a constant for the mod) or possibly come from other modding environments, which don't use events and/or don't have the explicit behavior of Factorio's global table. Their use...

For the uranium, there was a simpler option: void-powered lamps. Then at night the invisible lamps could start to emit uranium glows. registering uranium for destruction on chunk gen (LuaBootstrap.register_on_entity_destroyed) and using that to localise the lamp when the uranium is gone, would work....

result:

If an item on the ground is to_be_looted, it loses the status when cloned: /c local player = game.player local surface = player.surface local position = player.position position.x = position.x + 5 local spill_items = surface.spill_item_stack( position, --[[position]] {name = "iron-plate", ...

What are the units of the *_force version? It's likely not to matter: See: https://wiki.factorio.com/Types/Energy Also: core/lualib/util.lua, line 552: function util.parse_energy(energy) If the game sees joules, it uses those, else, divide watts by 60 (a lot of values in the prototype explorer are ...

A boolean to allow/disable picking up from belts would be nice. With an increased character_item_pickup_distance_bonus, it becomes easier to hold f to pick up non-lootable item-on-ground's... except near belts. I hate grabbing stuff on belts when I just want to pick up item-on-ground's, and I would ...

As side information, when discussed on the Discord, it based on PropertyTrees being [compatible with/existing as] json. json has the two types of containers: arrays and objects. Arrays only have numbered indices (from 1-N, a Lua sequence) and objects only have strings keys. Anything not a sequence c...

Just the map, or, map and global?

-> Updated for 1.1.79.

This request can be moved to a graveyard or whatever: After discussing it with rseding at length, it turned out supports bar is only a GUI modification: it shows or doesn't show the [X]. The inventory of the entity doesn't actually change. This behavior was then added to the wiki: https://wiki.facto...

A small bit with settings (global variable) and writing settings, it upsets github's Lua Lint or something, as it's listed as read only? I don't know how to better describe it: e.g. https://github.com/ILLISIS/Constructron-Continued/actions/runs/3782031980/jobs/6429423111 Related, under the descript...

"hide-from-fuel-tooltip", "hide-from-bonus-gui", "hidden" exist, but not hiding a module. There is also ammo tooltips, guns... any place in theory that can't hide things, supposing, but I am currently only desiring hiding a module. Obvious mod to see: Alien Loot Economy...

I wouldn't call this a bug - there is only one technology. upgrade = true is for when there are multiple technologies and "they should be shown as one that keeps going". https://wiki.factorio.com/Prototype/Technology#upgrade That's how upgrade's behavior is described, and that's how it's u...

cursor_stack_temporary returns false for a paste, but it's a blueprint that disappears when clear cursor is pressed.

Adding: it also doesn't work in just game.print:

In the bonuses screen, the bonus listed has 1 pre-added, which makes it incorrect for non-1 inserters.

The normal stack inserter capacity would be 1+2 = 3, the modded one in the tooltip, 4+2 is obviously not 3. Same thing for non-stack inserters.

This also occurs to me on Windows 7. For some reason another archive tool like 7-zip works fine.

https://lua-api.factorio.com/next/ exists, and at the time of this post, shows an outdated 1.1.53 version (neither stable nor experimental) I did a google search for LuaInventory, and noticed /next/ was one of the results, but... as mentioned, is outdated (current version 1.1.72) It appears /next/ c...

Maybe should be documented somewhere around map_gen_settings: "if there are no tiles defined to autoplace, the result for generation is always the first prototype tile, likely grass-1"

-> This is very specific and not 100% correct, we decided not to write this down.
