Script create_entity with fast_replace should replace belts between undergrounds

[Theis]

It would be nice if when using LuaSurface.create_entity to place the second underground belt or pipe to ground, if the transport belts or pipes between the pair were removed.

Top manual placement, bottom is placement through script.

Why?
It matches the description better

If true, building will attempt to simulate fast-replace building.

It matches the expectation, that when adding the second underground the game cleans up the extra entities.


It is for a TAS run, so simulating player behavior is critical. However i can also see, that i will be one the few people who need it.

I'd have thought that for a TAS run, player.build_from_cursor would be used. Idk if it has this functionality though.

I’m not sure, if those belts can be removed in any case without breaking something.

That doesn't matter. When manually placing the second underground belt, factorio will remove the belts in between, if they go in the same direction as the underground belt. OP is asking for the same action but triggered by script to do the same.

But, when trying to act like a player, the removed belts and their content need to go somewhere... Being a player sounds most reasonable:

Ah, this belongs to mod requests. Totally overseen. Moved.

I suppose it is worth a try.
I managed to recreate the functionality myself, so it isn't critical to change any more.
