The Battle for Wesnoth Forums

There's no official way. If wesnoth.scenario.__cfg exists, you might be able to get them from there.

Loading it back in is going to be pretty much the same procedure as saving it was. The scalar ones should be easy, literally the exact same loop you used to save but flip the assignment. Container variables will be a bit more tricky. I think something along these lines may work? local tags = {} for ...

The Lua API to global variables is not finalized, so it might change without warning, but it does exist. local GV = wesnoth.experimental.wml.global_vars local ns = "your_namespace" -- Set a global variable GV[ns].varname = "stuff" GV[ns]["varname"] = "stuff" -...

Wait until an add-on has a bug and writes millions of saves.

There is probably no way to save the entire game with all the information of a real saved game. You might be able to get close by writing wesnoth.scenario.__cfg (if that exists, didn't check) and also dumping every unit and maybe a few other things. Maybe I could copy/reproduce code for saving and l...

I don't think there's any reason why we couldn't have a way for an add-on to explicitly request a save or load, as long as: There are protections against overwriting other save files (maybe with the exception of save files explicitly requested by the same add-on). The user is not forced to load when...

I just want to note that if this has changed to actually working on the campaign rather than just "gathering information", you should probably create a new thread or at least rename the opening post and new posts.

Wesnoth provides no facility for writing arbitrary files, only for reading them. There is a facility for writing arbitrary WML to disk in a fixed location though – look for PersistenceWML.

I don't think there's any way to do that.

I thought that might be the case too, but I didn't read closely.

Even if that's a very nice portrait, it doesn't seem to match the style of Wesnoth?

This is an unexplored idea, so I don't know what way to implement it (the more elegant, the better) 1. How to disable reloading an older state of the game (or resulting into loading the latest one)? (my ideas: global variable saving ... ) 2. How to reload the game to one of its older states using c...

I think I would suggest using [filter_adjacent_location] instead of [filter_adjacent] . As you suspected, [filter_adjacent] requires a unit to be present (it is, after all, part of StandardUnitFilter). Something like this (untested): [harm_unit] [filter_location] [filter_adjacent_location] x,y=$hit_...

(Note: Some of these may sound more convincing with a few more typos and the like, or swapping out synonyms. Or if you just use them as inspiration rather than using them verbatim, that's fine too.) How could you ever think it would be fun for the main character to be killed off in the third scenar...
