The Battle for Wesnoth Forums

affected_units = wesnoth.get_units { side = "$side_number" , { "filter_location" , { terrain = "Ce" } } } The "affected_units" variable won't be used outside this block, so you may just as well declare it "local". for value in pairs(affected_units) ...

- It looks like I cannot implement ignore_ambush, but to be sure I need a confirmation: there is a Lua way to make the pathfinding engine take ambushes in account while calculating paths? I don't understand the question. Do you mean that invisible enemy units should be visible to your pathfinding? ...

At turn 11 a message "elves" is displayed? Indeed it is! (I ran a test) I can't imagine a purpose of such functionality of nested events... Why nested events don't work "normal" way? Just because you think it is abnormal doesn't mean it is. As for its purpose, consider the follo...

The term "delayed variable substitution" confused me. I always thought the variable substitution must be done at the moment the concrete line of the code is processed. It does. And in the case of a nested [event], the time the lines are processed is the time the event is created. (In orde...

This time I made two tags directly from FutureWML: [advance_unit] and [transform_unit]. Note that there is a new function wesnoth.transform_unit in 1.9.4 that might be suitable for these tags. Unfortunately, I didn't have time to document it yet. (But it shouldn't be long now that I have finished i...

I believe Kitty mentioned to me back in the day that a common practice of hers when downscaling portraits was to apply an Unsharp mask filter on the final 205x205 image. I don't remember whether any generic parameters were used or it was an ad hoc procedure. Theoretically, the cardinal theorem of i...

but can this be used also to simplify defining what that status affects and pershaps a default way of getting rid of it? That's orthogonal. The only thing that was missing for custom statuses was to display them the same way hardcoded ones are; so that's what I added. Everything else could already ...

Derived from [gold] and stuck in a scenario ([preload] event). All I've changed is gold to steal_gold to avoid identical functions. Looks like function wml_actions is only valid in core from the error message. Should I change it to local function and how do I change the name of inputs, e.g. side? T...

It looks inside a tag name the parameters are processed a non-standard way? Not really, the way they are preprocessed is the same as everywhere. (The preprocessor doesn't know what a tag is, it doesn't even know that [ and ] are special characters for Wesnoth.) I think your issue is that the parser...

It has been mentioned in the Lua changes for 1.9.4, but it might be worth advertising, especially since it doesn't really require any Lua knowledge. Let's suppose you want to define an "entangled" status (that is, an "entangled=yes" line inside the [status] tag of unit). How do y...

Almost all of the unit fields are correctly modified, but the "profile" field is not. It retains the portrait for the old HoRashti unit. I think this is a bug in the newfangled [modify_unit]. Any disagreement? The profile attribute is handled specially by the engine: if a unit advances an...

I have run some tests an it looks to me the algorithm that processes values is equal to this one: (?) quoted strings are identified all "+" outside quoted strings are deleted all "$" are processed 1 and 2 happens at load time. 3 happens at execution time. I expected parentheses ...

Because "$my_var"+"Two" is the same as "$my_varTwo".

I'm not going to get into themes, but I could add the current actual turn to the queue display. With the 1.9.4 engine, you can modify themes more easily. Adding the following lines near the start of the atb-utils.lua file does fix the turn count: function wesnoth.theme_items.turn() return { { "...
