I am currently developing a mod and I need to modify the behavior of underground pipe placement. The goal of this the script is to prevent the automatic placement of a second adjacent underground pipe when the player uses the click-and-drag feature. Ideally, ...

TL;DR Showing the max range always helps players aim at it directly instead of scrolling along the range. (For Factorio v2.0) What ? Always show underground max range visualization, while building the underground thing. Having the underground visualization change color depending on whether it ...

... should use higher level belts if available. What ? When dragging to place belts (or ghost belts), and an obstacle is reached which the current undergrounds cannot make it under, a higher level of belt should be used if it can make it, and is available. Example case: Before.png What you get: ...

I don’t see why pipes that can go underground should use a different naming scheme than transport belts that can go underground.

Or at least it seems, i currently haven't access to a factorio game so i'll just dump the clip :

I'll do some more tests later, but as i'll probably forget about it, maybe this clip is enough in the meantime

TL;DR Underground belts and pipes should be placed tile by tile instead of being one max length What ? Instead of underground belts being a fixed length, like 0 to 4 for yellow and 0 to 8 for blue, they should be placed one ...

If inserter has lane control drop for the entrance underground belt. The inserter can only drop to the outer lane. The top setup show how the iron plate is dropped. The expected behavior for the inserter drop is on the right setup. The left inserter ...

Right now, no event is triggered when an underground belt is rotated by dragging a belt over it in the opposite direction.

Could we add some event, such as on_player_rotated_entity, to detect this?

... I had dug up an old bug I reported way back with 0.15, but this behaviour is different. In a nutshell: inserting directly into the entrance of an underground belt behaves differently depending on the length of the underground section. Generally, when there is a 0- or 1-tile gap, it inserts as ...

Underground pipe ghosts delete pipe ghost when placed both sides of it.
Placing underground pipe ghosts first then pipe ghost inbetween works normal.

For feature parity with Prototype/TransportBelt#related_underground_belt and LuaEntityPrototype#related_underground_belt . It doesn't exist because pipes don't have smart drag quick replace function but I believe there is still a benefit to having it for inter mod compatibility. I already use LuaEnt...

Hello. Ive searched and didnt find this, when placing a ghost underground pipe i very often get it placed the wrong direction by the drones, so i have to push once more to re-direct the pipe. when pressing shift to place ghost it kinda rotates to the wrong ...

... acted as it should. The lines were similar with one slight modification in design: 1st line was feeding from the undeground IN (the head that goes underground) the second line was feeding from the OUT underground (the head where items come out from the ground). Each of the two lines of factories ...

... setup that each would sideload onto the six tile belt. The bug (perhaps) is when the player wants to replace the horizontal belt with an underground to have these five belts all cross. What happens is that if you start the underground belt in the right side of the setup, it will break ...

... where it will highlight through ghost entities in addition to normal entities. One of the properties used in the mod is LuaEntity.neighbours for underground belt connections, and that works fine for non-ghost belts. However, it cannot be used on ghost underground belts, which is unfortunate for ...

Attached is a video showing the difference between ghosting an underground over the top of existing belt vs placing it by hand and then undoing each. If one uses a ghost underground and then changes one's mind, the middle belt is still marked for deconstruction, ...

Ghost a yellow underground connection. Have a pair of blue (or red) undergrounds in inventory, whereof one is damaged. Place one of the blue undergrounds on top of the yellow underground ghost. Now you have 3 blue undergrounds.

I'm trying it right now, it seems the most challenging and I haven't found anyone having done this yet, It requires to think completely different I found compared to the normal game. Let me know what you think.

I recently started playing again after a long break, and the dashes for underground pathing seem to have gotten very soft, to the point where looking at them gets me feeling a bit cross-eyed and might give me a headache as my eyes struggle to focus on something ...

... (against item flow direction) dragging. First, the video demonstrates the "backward" action by starting to drag a red underground belt on top of a red underground belt and going "backwards." While still dragging, the belt is rotated and continued to drag backwards ...
