Pipe jamctions included? | Factorio | Page 1

So is this why you made pipe junctions for the jam?

ruby sand Mar 5, 2026, 12:45 AM

#

perhaps :D

#

i've had the idea written down forever but the timing was perfect

#

also, speedmodding is fun

hollow saddle Mar 5, 2026, 12:47 AM

#

Yeah do you think any can be added (other than an item description) to the mod? Could filters on the junctions be supported, like splitters?

ruby sand Mar 5, 2026, 12:50 AM

#

no complex functions, yet

#

i think i can do prio/filters with some jank but thats tbd

#

A rare mod that looks like it should be in the base game. Good work!

ruby sand Mar 5, 2026, 1:19 AM

#

:D

#

the best kind of praise!

#

ty!

I'm bookmarking it now...

hollow saddle Yeah do you think any can be added (other than an item description) to the mod? ...

hows this sound

#

A fluid junction, mostly evenly splitting fluid. Does not force fluid out, only prevents backflow. Change junction type with CTRL+R

hollow saddle Mar 5, 2026, 1:29 AM

#

Yes and mention the ctrl+r keybind

ruby sand Mar 5, 2026, 1:30 AM

#

great now how do i set that keybind link programmatically 😅 😅

#

ah __CONTROL__control-name__

swift prism Mar 5, 2026, 2:53 AM

#

WOW, that is amazing

#

this kind of logic is so hard to write

leaden knot Mar 5, 2026, 4:10 AM

#

tell me about it

ruby sand Mar 5, 2026, 4:29 AM

#

tell him about it

#

then tell me about integrating it into everything else 😅

#

full connection category and pipe connection detection

#

the only thing i cant do is check if machines currently have pipe connections active, like assemblers

west aurora Mar 5, 2026, 4:38 AM

#

Hell yeah! Can also confirm this stuff is crazy to implement, nice job!

ruby sand Mar 5, 2026, 4:43 AM

#

the only thing i dont have is per-connection connection_category checks but i think thats overkill

#

i only check per-entity

i do wanna make a feature request for this, it does seem useful

west aurora Mar 5, 2026, 4:44 AM

#

I forget if flow config has that. I lost steam on improving it since rotating blueprints doesn't work with it, though tbf it's been stable at least

#

This looks like a lot of fun to use

ruby sand Mar 5, 2026, 4:45 AM

#

rotating blueprints is a pain, i have to hotswap the entities to and from pipes to tanks

its so much fun one of the few mods im just sitting there playing with

You actually figured it out?? Nice!

#

I tried for like a month after releasing and had to scrap the attempts. Clever solution

ruby sand Mar 5, 2026, 4:47 AM

script.on_event(defines.events.on_player_setup_blueprint, function (event)
        local player = game.get_player(event.player_index)

  -- if normally invalid
        if not blueprint or not blueprint.valid_for_read then blueprint = player.cursor_stack end
  -- if non existant, cancel

      entity.name = xu.variations[xu.base_pipe[entity.name]][variation.mask]
      entity.direction = variation.direction
    end
  end

    -- just placed a blueprint, convert to normal
    if entity.type == "entity-ghost" and entity.ghost_type == "storage-tank" or entity.type == "storage-tank" then

      local new_entity = surface.create_entity{
        name = entity.name == "entity-ghost" and "entity-ghost" or new_name,
        ghost_name = entity.name == "entity-ghost" and new_name or nil,
        position = entity.position,
        quality = entity.quality,
        force = entity.force,
        player = event.player_index,
        undo_index = player and 1 or nil,
        create_build_effect_smoke = false,
      }
      entity.destroy()
      if player then
        storage.previous[player.index] = new_entity
      end
      if stack and not blueprint then
        stack.remove_undo_action(1, 1)
      end
      return

  end

inside the build event

and two whole annoying lookup tables LOL

Yeah I was trying to handle it by intercepting the rotate input event, which I think from my testing I concluded it wasn't guaranteed to happen before/after the blueprint is actually rotated...

ruby sand Mar 5, 2026, 4:50 AM

#

(oof)

#

oh wait not even garunteed? jeez

west aurora Mar 5, 2026, 4:52 AM

#

Yeah i was losing it trying to come to a good solution until I realized it's because it was one way or the other. And I think it depended per launch? I forget, would have to try it again and my advice is: just don't 😂

ruby sand Mar 5, 2026, 4:56 AM

#

when the best advice you can give is "dont" thats really good advice

#

also, no offense intended that flow config is incompatible, i just dont want to deal with compatibility bug reports with virtually identical mods

west aurora Mar 5, 2026, 5:12 AM

#

It totally makes sense, no offense felt at all

ruby sand Mar 5, 2026, 5:14 AM

#

fwiw i love the flow config UI and the initial implementation for this mod was almost an in-world version of it with a few tweaks

west aurora Mar 5, 2026, 5:16 AM

#

Thank you! Yeah I had a lot of fun with the UI
