Yes.



It's true that this can't be done with one group, but frankly liniting things to one group makes my life substantially easier. If this becomes a real pain as people write EffectsGroups, we can add support for multiple groups.



Documentation changes are always fast; its the code changes that take so long.

Is there a way to make a building affect max meter values for all planets in the system local to the building? Or is this only possible by using the conditions: WithinDistance and WithinStarlaneJumps.

If we can only use WithinDistance and WithinStarlaneJumps for this, then this could be a problem, because of the slow down you mention in the effects doc.

I imagine that buildings who affect objects within a radius of the building could be quite common, for intance a larger radius but +1 increase in meter values or a smaller radius but +3 increase in meter values.


Also, is it possible to have a limit on how many of a certain building can be built, eg I might want only one robot scientist buildable for the entire empire or maybe one per system. I guess it would be treated as a wonder perhaps, although I don't know if there is code for wonders yet.

Those are the conditions to use, ANDed with empireafflition (unless you want to effect planets from all empires.)



tz indicated in a earlier post that the this is fine. the slow down occurs when the conditition imbeded within the Within(X) is set to something other than <condintion::self/>.

See my example building, I believe it's well formed.




Good question, I don't know the answer.

One thing you can do right now is make the effect scope the entire empire, and the entire effect non-stackable. So the player might have two wonders in his empire, but will only see the benefits of one. (this is helpful for when/if the player caputures a second wonder from another player as well.)

We didn't really design the whole buildings model yet, so tzlaine has only really implemented the effects parts of them, and the basics like name, cost, build time, and maintainance. I think I whined about this at one point, but it never got done really.

There's actually a fair bit more we need to add to the buildings model from what's there now... such as:
Prerequisites for buildings (other than techs), such as presence of a special on/in Planet/System/Empire/Galaxy (or a more complicated resources-access system, which would be later extended to include resource trading), various properties of P/S/E/G in which building can be built (environment type, star colour, population, meters...)
Limits on number of buildings of given "building stacking group" in certain range or by number in P/S/E/G
How do deal with unpaid maintaiance or various other unmet-after-being-built prerequisites or conditions, perhaps with some property that effect conditions can acces to turn themselves on/off appropriately, like whether a building is "Enabled" or "Active"
Some form of obsolescence? tzlaine's forthcoming effects to alter building descriptions might do this

If you see a mistake in the tutorial, correct at will.

Your tutorials good.

Yes! That's exactly what was needed! Tnx a lot! With this we can finally have the ball rolling. And its finally answers most of the questions I have been asking for several weeks now :>

Great job guys!

Edit old tech posts into xml before adding new ones. Also you should make it tidy by presenting the tech with bold heading, description, effects in human language. Then do xml below in code form. Then do english language file stuff in code as well. Look at mine(learning page 2) or dreks as examples for presentation, etc.

Tech-check is now available. This is a utility app that checks your techs.xml file for correctness. You can download it at http://freeorion.sourceforge.net/designer-tools.zip . It has a very instructive README file, and I expect you to RTFM before asking a bunch of questions. I have placed an example techs.xml file here: http://cvs.sourceforge.net/viewcvs.py/* ... /techs.xml , and the latest eng_stringtable.txt file is as before here: http://cvs.sourceforge.net/viewcvs.py/* ... gtable.txt , so you can see what it looks like when it's working, if you're having some trouble with your own tech tree file. Enjoy.

Are there supposed to be errors in the example file?

For Con1d_AquaticDomes, you have:

Reading this file in Firefox gives an error, but tech-check doesn't seem to notice...?

Also, the newest eng_stringtable.txt doesn't have any of the techs from the example techs.xml you provide... Is this intended? (Why did I download a new eng_stringtable.txt ...?)

Edit: running tech-check on the provided techs.xml gives the following:

Running on this file: http://home.cogeco.ca/~toppingwebspace4/FO/techs.xml
gives:

The XML format I use is not strictly XML-compliant. The '::' substring is illegal XML syntax. So don't worry about it being incorrect, because my code expects such substrings.



I don't have those tech strings, because Drek didn't supply them. The new eng_stringtable.txt is however needed for the condition text to come out right.



Sorry about that; I forgot that there is a 24 hour delay in the public availability of files that I change on that site. Download eng_stringtable.txt again. It's now the correct version.



When I run that file, I get this:

It's not the :: that are the problem... Firefox doesn't even mention them when viewing my own techs in an XML file. The problem is the mismatched Type and PlanetType opening and closing tags in the example.

Otherwise, with the new eng_stringtable.txt, it seems to be working, other than all the "ERROR: Techname"-type stuff, which is expected, I gather.

Where do I get the eng_stringtable.txt file from. Can you provide a link.

You can download it here:
http://cvs.sourceforge.net/viewcvs.py/* ... gtable.txt
