bruteforce.py AI does nothing under 1.3.9

Quitch · Post by **Quitch** » October 18th, 2007, 10:12 pm

Installed the Windows version of 1.3.9 and setup a game which included the AI bruteforce.py, but it sat there without doing anything. Having been away from Wesnoth for a while I'm not sure if this is because it only works with certain factions, or doesn't work with this release.

It doesn't work with Windows releases as Python is not properly packaged with them. I think if you install python 2.5 from http://www.python.org on your system it will work.

Much appreciated

Is there a document which details what each AI is for or does? Sample I'm guessing is a base to work from, though since it's listed as a selectable AI does it have anything going for it? Bruteforce is some chess AI without looking ahead, but the other one... not so sure.

Installed Python 2.5.1 but only the default AI seems to work. Sample and dfool do nothing, while bruteforce charges its leader across the map without recruiting.

Seems something else also is wrong then. If you want you can file a bug report on gna.org, so it will be fixed eventually. I'll look at it now but not sure I'll have time to reproduce/locate the problem and fix it.

Hm, seems to work here in linux. Can you paste the contents of the stderr.txt file from a run of the game where you tried to play with bruteforce.py?

Try removing the extremely outdated python.dll shipping with Wesnoth, so it will pick up the 2.5 one.

Quitch · Post by **Quitch** » October 23rd, 2007, 11:45 am

It generates an error complaining that the .dll is missing.

However, Python doesn't appear to have inserted anything in my PATH to point programs to the Python folder, so unless it installs DLLs into the Windows system folders...

allefant · Post by **allefant** » October 23rd, 2007, 3:54 pm

I see. I don't know then. My expectation was if you "install" Python 2.5, it somehow is found by all Python programs, but that may be wrong.

The ideal solution of course would be to recompile Wesnoth against Python 2.5 and distribute not only the .dll but also the required support files - but I don't think we currently have anyone who knows how to do that.

dagoi-koi · Post by **dagoi-koi** » November 1st, 2007, 8:03 pm

Solution: After installing python, take the python25.dll from the python directory. Rename it python23.dll and replace the python23.dll in Wesnoth directory. Then bruteforce.py will work.

You may want to backup the original dll if you have problems.

Quitch · Post by **Quitch** » November 1st, 2007, 9:59 pm

Excellent, that does seem to have solved the problem. dmfool_ai doesn't seem to do anything... it just doesn't work with 1.3.9, or it isn't supposed to do anything? Seems odd to have it there.

What's the difference between a .py AI and one without .py?

Post by VS » November 1st, 2007, 10:25 pm

Some AIs (default, dfool (?)) are hardwired into the game itself, while the .py ones are scripted in Python and can be added ... well, independently on the other stuff. Like you add eras and campaigns (by downloading), you can add your own AI (if you write it first, of course).

Quitch · Post by **Quitch** » November 1st, 2007, 11:06 pm

There did seem to be a nasty memory leak going on. I pitted all five AIs in a FFA and soon Wesnoth was using over 1.5GB RAM.
