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.

For defines.events.on_game_created_from_scenario we could add the additional note that "This event is not fired when the scenario is loaded via the map editor", a fact I discovered only after digging around a bit. This would be useful to note that this event could be used to detect whethe...

Oh, so to change the "grid position" I would edit the positions of all the blueprint entities.

A get/set_grid_position still could be useful, though.
But even if not implemented, at least the grid position behavior should be documented somewhere.

Currently (v1.1.35) there is no way to read/write the "Grid position" setting of blueprints from lua (on LuaItemStack). Could we get this feature? There is an older forum post on this topic https://forums.factorio.com/viewtopic.php?f=28&t=96815 marked "solved", but it only de...

Here's a portion of the code that produced the crash: -- (in a function) local blueprint = getBpForLayer() -- creates and returns a LuaItemStack in a script inventory, that is a blueprint local blueprintedEntities = blueprint.create_blueprint({surface = self.surface, force = "player", area...

I'm creating a (yet to be released) mod that involves programmatically creating/pasting blueprints. In the mod, using lua, I created a blueprint (inside a container inside a custom surface to hold the LuaItemStack), set blueprint_position_relative_to_grid, but did not set blueprint_snap_to_grid. Whe...
