I posted a patch to implement Sanna's [objectives] WML tag to Savannah: http://savannah.nongnu.org/patch/index. ... em_id=3789

This tag allows setting of scenario objectives as events: This tag is backwards compatible with the existing usage: Note the special colour indicators and the need to have the string running across newlines. The new tag simply overwrites the value of the string that stores the objectives. Using [objectives] tags, the scenario objectives can be changed as many times as the scenario designer wishes: randomly, every few turns, every step, when reaching a specific hex, on attack, or any other event.

Here is how it can be used in a moveto event:

Summary of features:

requires no changes to existing campaigns,
fills in the colours for defeat and victory conditions automatically,
can display objectives when they change (thanks to Invisible Philosopher for suggesting),
eases translations, and
adds a "quick summary" line to objectives.

Several campaign developers use hacks to change objectives mid-scenario. Turin has mentioned having a use for changing objectives, but is this patch worth including in the mainline distribution? If you think so, please state your opinion here, or even better, help to improve the patch so it doesn't muck around quite so much with global data structures. Right now the patch is languishing without any serious developer review, and needs to be updated frequently to keep up with CVS.

Awesome. Is the summary key displayed in addition to the "OBJECTIVES" line or does it replace it? Sounds like it is in addition.

I for one would love to see this in the main line. There are three (possibly four) scenarios in The South Guard where I'd use it.

I'd like to see this make CVS too, because I will be able to have Kogw appear on turn 3 (Blue River, FtF), like I had planned.

This would be awesome. If this gets implemented I could use it a plethora of times in my campaign. Thanks so much for making the patch.

Could this patch be enhanced, to use another tag, normally only available at
scenario start:
[story] in an event ?

Mid-scenario cutscenes? I love that idea.

Yes, i had this in mind, but it would have another side effect :

Cutscenes could be taken out of a wml pseudo database.

Greetings, Fabi

This would also be useful, but it would probably be a different patch, not an extension.

--------

Many campaign developers could use this, and almost all agree it is a good idea. I think it should be implemented as soon as practical.

Me too.

You seem to be asking for more of the start-of-scenario initializations to be made into events. Perhaps you could start a new thread to discuss that -- seems to be a worthwhile idea, since (as I demonstrate with [objectives]) they can be put into a name=prestart event to achieve the same effect as the current start-of-scenario settings. Being more general, this would probably also simplify the parsing code.

The summary is concatenated with the victory and defeat objectives and the result put into the same place that the current objectives= attribute is stored. Forcemstr and Ayin have both taken a serious look at this code, but the exact location in the config data structure of where the objectives= attribute should be stored is currently under debate. It looks like it will be moved to a different place, once Ayin finds time to look at this again.

ott: Okay, a modified version of your patch has been commited, along with the ability to define per-side objectives.



The old way of defining objectives, which is to supply an "objectives=" value into the level, is still supported, but is considered obsolete, in favour of using prestart events setting objectives. The old way of setting objectives sets them for all sides.

[objective] events replace the current objectives, and do not merge them.

When the objectives of a player change during his turn, an "objectives" dialog automatically appears.

When the objectives of a player A change during player B's turn, the "objectives" dialog appear only to player A when it's his turn.

Objective changes for other players do never appear (those are, however, sent to clients, so cheaters may see them anyway.)

Does side take a list?

For multiple win or loss conditions, do you use multiple [objective] tags or make a multiline string?

edit:
Can you leave out victory_string, defeat_string, and summary and get default values of "Victory:" "Defeat:" and ""?
Or any other keys for that matter?
side?

You may do either, but using multiple [objective] tags is strongly recommended: this allows re-using strings, and lessens the work of translators.



If you do not define them, they have the default values. My example was quite bad, indeed: as they are left to default values, they should not have been defined.
