Several of our mainline campaigns are in the works for upgrades at the moment, which includes adding characters and enhancing existing scenarios. We are looking for more artwork to supplement these upgrades, including the following:
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,...

It looks good at the bottom since the page isnt too long; i had no problem finding it.

There is also a partially-complete WML Tutorial which would be helpful to the WML newcomer. Note that it is a work-in-progress and that some sections are more complete than others, but it does exist. The ReferenceWML page, while extremely helpful to those who already understand WML, can be...
Here you can find configuration files to enable WML syntax highlighting for various text editors :

Just for the record, for those on Linux (at least Ubuntu and consorts) who don't want to fuss, KWrite can do WML highlighting natively.
That's what I've been using for years, since it's included in my software manager lineup.
It's very easy to modify the highlighting rules (there is a nice menu...

totally YMMV

Would love if there was a link to a thread on "Balancing" maps/factions/etc.
not sureifyou have found this already, but here is a guide on faction design/balancing as you requested
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 came up with the weapon special for a fencer-like unit: Challenge.
If the units attacks the oponent, it challenges it for a duel. Both unit would receive status "challenged" and will not be able to move and attack any other units but each other until one of them gets killed. Also none of the...

Thank you all for answers. I think [disable] is the cleanest way. Didn't know I could just filter opponents inside the special.

I think I have it working.
I had to ensure that the unit vars had the correct value when the ability filter saw them plus, as they are static values I didn't need to use unit variables. I wanted this code to work with variables and this seems to work:

That is pretty basic vocabulary. Perhaps you could use this:

You also need to know that all tags have a strict list of accepted sub-tabs and keys. Anything not in that list is ignored. Ravana is saying that...
I have noticed the standard [teleport] doesn't work for the AI: They can land right on a teleporter tile and nothing happens.

I would do it differently. Instead of using a variable, I would use a nested event.

You may have discovered a bug, though it's not likely. It's more likely that you are not analyzing your code correctly. (This is nothing against you: I have only ever discovered one bug when I thought I had, and it turned out that I was analyzing my code incorrectly at least 50 times.)

Broadly speaking, [modify_unit] is better for changing temporary values such as moves, current HP, or variables, while [object and friends is better for permanent or semi-permanent values such as max HP, abilities, or resistances.
I want to put a picture under the little campaign selection text, the one you see when you scroll through all installed campaigns in the game.
Unfortunately apparently the binary path has not yet been read when _main.cfg is parsed, because the game doesn't show my picture. In other words, m...

In your last thread you already learned to set income to -2.

Anyway, for anybody who finds this thread through searching, the solution is here.
Back in 1.12 it only worked for the length of a scenario, but wouldn't be ported to the next scenario.
The suggested solution was to use {TRAIT_LOYAL} instead.
Is this still true or has this been fixed? Do you still have to use a trait to keep a unit free...

Probably not, but you could look at the source code for campaigns like LotI to see how they do it.
This should be easy but I can't find the solution. I have tried including \n in the string and even \\n (in case it needs escaping). Once I know it will be obvious but I can't find it with various searches....

If you find the indentation too ugly, you could do something like this:
it seems weird that, for some reason, the pre-attack calculation does not simply use the actual HP for the calculation (well it does) but seems to cap it off at max HP, if for some reason if the HP is higher than that.
so all calculations with HP higher than max HP are wrong and there is...

I am creating a unit in a [moveto] event, which is fine. I specify x,y=$x1,$y1, so the unit is placed north-west of the one that has just moved to that location (always).
