A couple of questions

[MrEPIC]

Did you ever figure out the problem with the illuminate halo? I don't see anything that's obviously wrong in the code that would cause the effect you were getting.

No, I still haven't figured that out yet...

Note, if you have already deleted an object/modification from a unit, then you can force the unit to be rebuilt from its base type using the TRANSFORM_UNIT macro.

For example:

Code: Select all

{TRANSFORM_UNIT id=$unit.id $unit.type}

This essentially levels the unit up into itself, then sets its hitpoints, experience, and status variables back.

Thank you for this advice, it should help.

[MrEPIC]

Hello again, I have another question:
How can I make the AI send units to a specific place on the map?
I know that I can use leader_goal to tell the leader to go somewhere and use protect_location to tell the AI to send units somewhere if there's an enemy nearby but I'm just wondering if there's any way to tell the AI to send units to a place on the map to do something like try to get to an item before the player.

Thanks for any help!

Oh, and by the way, if anybody has any answers to my first question about giving a unit the illuminates aura, please answer

[dvormann]

Regardinghe the illuminate halo. Does [object] work, i.e. the unit gains magical arcane?

What does {ABILITY_ILLUMINATES_THW} do? Can you post that? I guess there is a differnce to standard {ABILITY_ILLUMINATES}.

I'd like to find out if {ABILITY_ILLUMINATES_THW} uses variables X or Y in any way?

Can you place a debug message between [/object] and [unit_overlay] that displays values of X any Y? Should read:

Code: Select all

[/object]
{DEBUG_MSG "{X} {Y}"}
[unit_overlay]

The object works, and ABILITY_ILLUMINATES_THW is just illuminates with a changed description. The DEBUG_MSG works too.

[dvormann]

What does the debug message say? Do X and Y have the correct coordinates?

The Debug message says the coordinates of the shop.

[dvormann]

The ways I understand it you have the following:

Code: Select all

                                    {DEBUG_MSG "{X} {Y}"}
                                    [unit_overlay]
                                        x={X}
                                        y={Y}
                                        image=halo/illuminates-aura.png
                                    [/unit_overlay]

The message prints one set of coordinates and the halo appears somewhere else. Something is wrong with {X} and {Y}.

For debugging, you can try:

a) replace x={X} y={Y} with the actual coordinates of the shop. Does the halo appear in the right place? (I hope it does but maybe there's something wrong with your version of Wesnoth.)
b)

Code: Select all

                                    {DEBUG_MSG "{X} {Y}"}
                                    [unit_overlay]
                                        x={X}
                                        y={Y}
                                        {DEBUG_MSG "{X} {Y}"}
                                        image=halo/illuminates-aura.png
                                    [/unit_overlay]
                                    {DEBUG_MSG "{X} {Y}"}

Do all three messages print the same set of coordinates?

Another idea: Perhaps unit_overlay does not like {}.

In that case try

Code: Select all

                                    [set_variable]
                                        name=usex
                                        value={X}
                                    [/set_variable]
                                    [set_variable]
                                        name=usey
                                        value={Y}
                                    [/set_variable]
                                    [unit_overlay]
                                        x=$usex
                                        y=$usey
                                        image=halo/illuminates-aura.png
                                    [/unit_overlay]

That's not how WML works. You can't put things in random places and expect them to work. In particular, the debug message inside the [unit_overlay] won't have any effect.

Another idea: Perhaps unit_overlay does not like {}.

Brackets are preprocessor symbols, which are expanded only once (usually the first time you run a campaign). By the time [unit_overlay] is run, the brackets have long disappeared and their content been replaced. If it doesn't work with [unit_overlay], it won't work either with [set_variable].

[dvormann]

The problem is unsolved for two weeks. Most people seem to agree that the code as published _should_ work. So I am looking for unlikely solutions. Like WML not working in exactly the way one expects it to.

However, I have yet another idea:

It is a moveto event, right? If the wiki can be trusted (of which I am not sure) then the loaction the unit moved to is stored in x1 and y1. So, in theory, {X} and x1 should have the same value. Try replacing {X} and {Y} with $x1 and $y1.

He's trying to use an image bigger than 72x72, that's the problem apparently. It don't work.

I also tried this with the cave beam from the map editor (images/terrain/cave/beam.png), which shouldn't be larger than 72x72 because it fits on one hex, and it also doesn't work, and appears on a different part of the map. Or am I thinking wrong and this image is also too large?

[Iris]

Note that for adding the illuminates ability aura you should be setting the unit's halo as in:

Code: Select all

[store_unit]
    [filter]
        ...
    [/filter]
    variable=stored_unit
[/store_unit]

{VARIABLE stored_unit.halo path/to/illuminates/aura.png}

[unstore_unit]
    variable=stored_unit
    find_vacant=no
[/unstore_unit]

However I believe this doesn't currently work - IIRC the engine automatically resets the halo to the unit type's default, or none if it does not have one.

Your cave beam overlay won't work for two reasons:

a) the leading images/ ; the engine will try to locate it in paths like /data/core/images/images/... instead.
b) beam.png is 180x216 pixels in 1.6 and 1.7.

The terrain builder engine does some magic to center it on a single hex; the same magic that is used with other terrain graphics which are larger than 72x72 or aren't even centered by themselves.

Although almost 10 months have passed since the last post here, I decided to continue to use this as my workshop help thread.
Now I arrive with a new question about lua:

Spoiler:

Although I have never tried coding anything in lua, and in my knowledge in this area is next to none, I decided to try to make a simple script that would iterate over the sides in a game and return the total count and each team name. Here's what I have:

Code: Select all

function side_info()
	local s = 0
	local team_names = {}
	for t in H.all_teams() do
		s = s + 1
		table.insert(team_names,s,t.team_name)
	end
--	wesnoth.message("LUA_team_names",table.concat((team_names),", "))
	return s,team_names
end
local total_sides,team_names = side_info()

wesnoth.set_variable("thw_total_sides",total_sides)
wesnoth.set_variable("thw_total_sides_temp",total_sides)
H.set_variable_array("lua_side_info",team_names)

The total number of sides (s) is correctly returned and the commented wesnoth.message correctly prints out all of the team names to the chat area. However, when I use :inspect to check "lua_side_info," it shows a number of empty [lua_side_info] containers(is that the right term?). This leads me to believe that I did not correctly use helper.set_variable_array or should have done something else. Does anybody know how I could use the team_names table in WML?

Another question: Are seperate lua files (for example wesnoth.dofile(file.lua)) transmitted over multiplayer?

Thanks for all help, I'm still learning lua so don't be surprised if I made an obvious mistake.

[silene]

However, when I use :inspect to check "lua_side_info," it shows a number of empty [lua_side_info] containers(is that the right term?).

WML doesn't have arrays, it only has sequence of containers. So the following should fill the [lua_side_info] containers with a name= attribute.

Code: Select all

table.insert(team_names, { name = t.team_name })

Another question: Are seperate lua files (for example wesnoth.dofile(file.lua)) transmitted over multiplayer?

Only the content of scenarios is sent over the network. Everything else (separate lua files, unit types, unit graphisms, and so on) has to be installed locally, for instance through an era.
