Avoid hard-coding collision masks. You don't know what other mods might be using it.

Instead, use this:
Then you can assign collision_mask = {air_unit_layer} and add it to the projectile.

I could suggest a whole range of new TipTrigger types, like MineEntityTipTrigger, DamageTakenTipTrigger, and many more, as it seems like the existing set of triggers were specifically made for whatever the default tips and tricks need and don't yet offer much flexibility. But even with a wider range...

Would it be at all possible to do something like runtime-api.json but for the data stage? Defining what prototype classes exist, what properties they can/must have, what types, etc.? I feel like this could be a massive help for data-stage modding, just as runtime-api.json has been a massive help fo...

/c for _,turret in pairs(game.player.surface.find_entities_filtered{type="turret"}) do if turret.name:find("worm") then turret.force = "enemy" end end Should search the current surface for all turrets, then narrow the search to turrets with "worm" in their na...

LuaSurface.get_closest() is very useful. I'm pretty sure it's orders of magnitude faster than sorting the list of entities on the Lua side, given it would need to constantly query the engine for entity positions and such. I would very much like to extend this function with an optional "count&q...

detecting the player messing with modded entities that require certain wires to function Note that you can also mess with wires using blueprints, so on_player_used_wire would not solve everything. Fair point. Just putting a power pole too close can also "mess with" stuff, but those two ca...

data:extend{ { type = "recipe", name = "recycle-empty-barrel", category = "crafting", energy_required = 1, ingredients = {{"empty-barrel",1}}, result = "steel-plate", -- or results = {{type="item", name="steel-plate", amount=1, p...

Okay that might not be the best name, but I would like to have an event for when the player connects (or disconnects) two entities with wire. Event properties: - wire: "copper", "red", "green" - from, to: the entity/connection points that were joined or disconnected - d...

How can I add another item that is able to connect power poles? (Connecting them with copper is fine, but how does the base game determine this?)

Point 1 is resolved by using a decent framework, or making your own - it's a fairly trivial matter to define a function, say "create_window", and let that handle creating the close button etc. Points 2 and 3 are resolved by setting "player.opened = window". The player can only ha...

thanks i didnt notice the subforum this was in. rseding was like "i dont give a fuck" when he broke the functionality so i didnt expect this to ever get fixed Many, many things have gone from "won't ever happen" to "Oh wait..." to "Okay done," sometimes even ...

its too late, the stubbornness of rseding made me quit modding and afaik they even still havent fixed this. sorry You claim to have quit but yet here you are coming back nine months later to bitch about something in the "implemented requests" forum saying they "still haven't fixed it...

Tool s have prototype properties to describe how the durability should appear in the tooltip, but the actual usage of this isn't documented. From looking at core.cfg it would appear that the locale entry gets given: __1__: remaining durability __2__: total durability __3__: durability as a percenta...

Yes, if you have a reference to a resource entity you can check `entity.prototype.resource_category`.

What happens if you set the flow's width to zero and then apply negative left margin to the frame itself?

But be aware that other mods may introduce more categories.

Since September of last year I've been working on an overhaul mod: Satisfactorio . At this point is it pretty much feature-complete, and I'm in final testing before I look into releasing it. However, I am not a graphics person. All of my buildings are currently just big white placeholder rectangles ...

Currently, all weapons share a cooldown, and all capsules share a cooldown. I have a powerful healing item that fully heals your character but has a several second long cooldown. During this cooldown, it's impossible to throw grenades because they are also capsules. I would like to suggest a `cooldo...

Since mods are loaded in alphabetical order (when not referenced by dependency) then you can name your mod accordingly. This is what happened back when 0.18 changed how shortcut prototypes worked, which was a breaking change for many QoL mods. Rather than wait for all the mod makers to patch it, som...
