Have a spidertron with roboport. Do an action (building/deconstructing) to let some robots swarm out. While they are outside of the spidertron, mine the spidertron in remote view to mark it for deconstruction. Now the robots send an alert "not enough empty roboport slots available" and stay on their ...

Thanks, how genius is that!

Allow the "Anything" or "All" signal in circuit wait conditions for trains.

Try to insert the category in data-final-fixes.lua

What is not working?

I don't think thats possible, as multioctave_noise is a built-in function that is not defined anywhere in Lua code

If the ghost has tags set, you will find them in the event data

For the technology issue, do you have specified the recipe twice as unlock-recipe?

I thinked of this when doing a mod. The problem is that entity "upgrade" is not always a compatible upgrade, specially underground belt, if you paste a blueprint that do underground belt spaghetti, and downgrade all of them to the same underground tier the blueprint will not work. Also range of ...

Are all the requirements met mentioned in https://lua-api.factorio.com/latest/pro ... xt_upgrade?

You know, this is the solution. Thanks a lot! I don't even need a "dummy" force, just setting the ghost to neutral makes the logistic network not trying to deliver items.

For internal reasons, I have an entity which I create as a ghost and destroy it usually. To make it placeable as a ghost, I had to create a dummy item with place_result set to this entity. However, if this ghost is placed inside a logistic network, it shows that the ghost is missing materials for ...

I created the mod. It was not as complex as I initially thought:
https://mods.factorio.com/mod/blueprint-auto-downgrade

I'd be interested in (co-)developing such a mod. My idea is to provide a dialog upon placement, if one of the entities is not available in the logistic network. Then for each of those entities (maybe also include a check if available entities >= amount needed), show possible candidates to replace ...

Whatever is best for UPS. I'd say only a few mods use the undo/redo API at all.
For me, as a programmer, it is more useful (or convenient) if entries of an array of UndoRedoActions really are UndoRedoActions (having a type and some data). If you decide to leave it as-is, please add a hint to the ...

So, looking into this - a given undo item can have several actions in that item and one or more may be invalid. When pushing the structure to Lua the push logic will skip invalid entries however it still increments the index that it uses to put the undo item actions into the lua table.

I can "fix ...

Can you provide a save file created between steps 3 and 4? i am unable to reproduce any issues and i suspect i am misunderstanding which actions are super forced or normal or ghost or blueprint builds.


Rotate the belt in the cursor so that is is not facing north. Place it where the ...

Steps to reproduce:
1. Build a belt
2. Super-force build a splitter (belt is now marked for deconstruction and splitter ghost is created)
3. Place the belt again in another direction on the same position (splitter ghost is removed)
4. Print the last undo item. The first entry is nil
/c game.print ...

The only event that is fired related to that is on_player_cursor_stack_changed when you insert a non-ghost module

Steps to reproduce:
Use the mod I attached. Place 2 electric poles and connect them with red or green wire. Then press Ctrl+Z. The floating text states that the connection was undone, but no chat message.

When I disconnect a wire connection by script the next tick after it was connected and I want ...
