Thanks for the quick reply. It seems the error is not unknown after all...
It's probably a low priority thing, but as a suggestion could this error message become less unknown and more descriptive?

When trying to upload a new version of my mod, I get a message that says "Unknown error (PY)". The message kindly told me to open a support forum here.

Attached is the mod zip.

Any help is appreciated; thanks in advance!

Here's a possibly related crash, that occurs in 1.1.95 (but not 1.1.94): I'm abusing a rail-remnants prototype to get a simple entity with the collision box of a curved rail. Making an educated guess from the stack trace, changing the time_to_live of that prototype from max 32-bit int (the type docu...

Right now, AFAIK there is no API to read or write to blueprint descriptions.

I have a mod which deals with creating blueprints; it would be nice if I would allow users to save/write to descriptions, but this is currently not (reasonably) possible to do.

Another potential way to do this is to add a "old unit_number" field to events when undo is done. This means more work for the mod, but at least the mod can detect the undo and what entity it used to correspond to.

I also have a use case for this (checking module changes).

My current workaround is making a check for changes during on_player_cursor_changed, but that's inefficient and a bit hacky.

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?

It is often desirable to attach some data to an entity, this can be done for instance, with a table by unit_number in global. However an entity is deleted, then the deletion is un-done. there is no way to remember or recover this data. The unit number changes, there's no other identifying info. The ...

This looks similar to viewtopic.php?f=182&t=105527

I looked at that post, and I think this may not be quite that similar:
- I'm using x11, not Wayland
- Importing the large string still works in earlier factorio versions (1.1.72)

When I try to paste a very string into the import blueprint window, the game pauses for half a second, and nothing is pasted; I can't import the blueprint (book). Importing a large string works fine with an earlier factorio version (1.1.72); I have that version installed elsewhere and just tested it...

2 things: LuaSurface::entity_prototype_collides and decorative_prototype_collides return a boolean; not nothing. They also have no description, so I'm guessing what they do from the name. In my testing LuaItemStack::default_icons is of type of type BlueprintSignalIcon[], not BlueprintItemIcon[]. Th...

It would be great to allow a selection tool to have user-configurable filters, like with the deconstruction planner.
Using a deconstruction item prototype doesn't work, as it limits you to just creating another deconstruction planner.

Steps to reproduce: - Create a freeplay save (no mods) - Go to editor mode (this pauses ticks) - Build an entity (tested with iron-chest) - Create a highlight box around that entity ( /c game.surfaces[1].create_entity{name = "highlight-box", position = game.player.selected.position, target...

Late reply is better than never! Still happens in 1.1.69 Apparently, this only happens with the "freeplay" scenario (maybe has something to do with the cutscene?) Steps to reproduce: 1. Create a mod that uses on_player_created and on_player_changed_position; example control.lua: script.on_...

It would be useful to be able to "display" an entity, like in the cursor entity/blueprint preview. Something like rendering.draw_entity { name, surface, target, tint, direction, etc... } could accomplish this. I don't think there's currently way to do this: Entity-ghost runs into too many ...

In a mod, I initialize some data in on_player_created (and during on_init), and use it during on_player_changed_position. However, when creating a new save (freeplay scenario), on_player_changed_position was raised before on_player_created, which led to a crash (attempt to index nil, the player data...

Title says it all. This would allow testing (soft) mod setup behaviour without having to leave the map editor, create a new save, test, quit, reopen the map editor...


Edit: grammar

When a file is imported using "__modname__.path.to.file", the behaviour of "require" within that file changes (vs a "normal" require). Based on my observations: If the file is in the root of the mod directory, relative imports do not work at all. If the file is in a fol...

It seems LocalisedString also allows boolean values (and even nil in many cases); this could be documented.

-> Thanks, this is clarified for the next release.
