This lists removed WML functionality and helpful hints for avoiding pitfalls.

We are happy to announce that Wesnoth is now able to accept donations on Liberapay . While Wesnoth does rely on the work of dedicated volunteers, no project can function completely cost-free. Revenue from the Apple App Store and from donations goes towards maintaining our servers,...
There have been numerous important forum posts and wiki articles written by users and developers. We reference these pages a lot, and decided to put them together in a convenient list.
Write clearly, be nice to others, and be very careful when posting anything related to politics or religion. When asking for help, remember that everyone here is a volunteer. Prefer editing your previous post over double posting. No animated avatars or graphical signatures. Don’t plagiarize other’s...
Here you can find configuration files to enable WML syntax highlighting for various text editors :
Gedit (and other Gnome based editors): Has full WML support and partial inline lua support.
wml.lang goes in /usr/share/gtksourceview-3.0/language-specs .
cobalt-wml.xml goes in...
The purpose of this thread is to provide links to particularly useful information and code examples of WML and Lua on the wiki, without cluttering up this forum with more and more stickies. As such, the wiki pages linked here should be kept working and up to date - if an unmodified piece of example...
Does you campaign produce obscure WML errors on startup and you don't know what line in your 2000 lines of WML causes it? Instead of going through everything line by line and try to spot the mistake you've made, or before posting your entire campaign on the forums in the hopes that someone wants to...
People often use WML attribute or tag names that are misspelled or just plain fictitious when trying to debug WML — or even tag structures that (to the trained eye) are logical to the writer but have no basis in reality. You should always look up the proper format first, and we have a dedicated...
I'm creating a unit, the suicide drone. It has a weapon special 'explosive detonation' whereby if it hits it explodes doing self.hitpoints to himself and all adjacent units. It also has trait 'unstable', so if you hit it with impact, again an Earth-shattering kaboom! Kind of a fun little guy. This...
WML and I don't get along real well. It does a lot of things I don't like, I assume in the name of being user friendly . I'm just not sure if this is one of those times, or if it's a bug (I'm strongly in favor of the latter).
In the following code, always happens, regardless of the value of...
How can i convert traits from specific campaigns to those traits that come by default (like skirmisher or submerge)
I wanted to just copy everything (imo) relevant to disengage trait but it doesn't work properly (actually it doesn't work at all, only the description)
also why this doesn't work, its...
I'm creating a suicide bomber. When it attacks on offense it explodes, killing itself and damaging all adjacent units for the attacker's hitpoints. I have all this working, but I can't get the sounds right. I want it to use explosion.ogg when the special is active, and lightning.ogg when it is not...
I want to give Side 2 a one-time infusion of 100 gold on Turn 20. Not finding any simple syntax to accomplish this, and everything I search just takes me farther down a rabbit hole.
there is a scenario named Pebbles_in_the_Flood
from The_South_Guard campaign
there are such enemies with invulnerable status
where is this status defined? how can i use it in my campaigns or to attach this status to my created units
I have to be missing something here. Without using lua, how do I simply clone a unit? I want to make a copy of a leader, and then change a few things (like canrecruit).
I could make a new unit and copy all its attributes. I guess that's simple, but tedious.
As you can see, the whole modify_unit block is pretty redundant, which bothers me (there are a more s, just showing two as an example). I'd like to do something like this (code is wrong, hopefully my intent will be clear):
I want to print a message only if the number of undead, both on the map and on the recall list. This has led me to some questions. So many it's time to ask for help.
(I know, use lua. But I want to learn some stuff)
Only somewhat related, can I ever use count as anything but a filter? Seems...
Hi I try to build an ability who deal adjacent damage at the end the of turn, based on the owner current HP.
With my event i have an error message in the game debug console when the event triggers (and match filters) :
attempt to perform arithmetic on a nil value (local 'base_damage')
I'd like to set multiple objectives which all must be met for a side's victory. eg, take cities a AND b, AND kill the enemy leader. It appears from what I've been looking at that all objectives are mutually exclusive, eg take city a OR b, OR kill the enemy leader. I want victory to happen when all...
Supposing a side's leader earns enough XP during a scenario to advance in rank. But the next scenario has him set up as his previous rank. How does the game handle this?
eg, suppose Side 1's leader is a Dragoon but kills enough bad guys to qualify for Cavalier. But the next scenario's .cfg has him...
I store some side=7 units into units_to_micro_ai array, hat works fine.
But the works unexpected(leader starts moving to 36,7 while units on units_to_micro_ai array keep fighting)
(I'm working on retreat micro-ai for nagas that aren't in water, then I want to add them lurker micro_ai so they'll...
I want to play a short bugle call and show a picture on the scenario start screen.
Picture works fine. (well, it won't scale; can the picture's size be changed? The text window covers the bottom, would like the pic not to overflow into the text window) Music won't play. It was placed in the...
To no surprise of mine, when I tried to start my campaign from the campaign menu, it returned a very verbose error message. So verbose, I wanted to take a screenshot so I wouldn't get it wrong.
There is no default hot key for a screenshot, so I went into Preferences and assigned f12 to the job. I...
I'm looking at creating a few units whose mission is to target a human-controlled leader. At the moment, using the simple_attack micro_ai. Each time I create one of these units, I create a CA for it, so I end up with something like this:
In this particular case, I doubt I have to worry about...
I'm looking at ai for the first time, and I'm a bit overwhelmed. The wiki seems like more of a reference than a guide, describing some interesting pieces, but not how to put them together.
I have a scenario which I think will provide a good example to get me started, as I have the same basic need...
Hi,
1. Any idea how to display long text on multiple lines, rather than with slider? ... and then all the lines align in center?
(like when you type long string into )

2. How to display it only in top of map, not on top of the right panel?

I have included some standard macros in my scenario .cfg file.
They are macros used in virtually every scenario supplied with the game.
The Campaigns folder for these games do not define any of these macros (eg, GOLD or even DEFAULT_SCHEDULE ), they only define custom...
I finally started to dwell into the WML stuff and successfully created a _main.cfg and a first scenario file which worked fine for some time until I tried to make an moveto event which killed my file. Now I can´t find where to locate the is missing name or id field.
It worked before, but it seems I...
