Problem with Jar files #230

Closed yodatk closed 4 years ago

yodatk commented 4 years ago

I have written a Uci Protocol chess Engine in kotlin, the executable is a jar file, which was tested and runs in arena. I have put the engine file in the "engine" subfolder, and edited the config file accordingly.

when trying to boot the lichess-bot.py, the engine connects to the game but doesnt make the first move, those line appear in -v mode: 2020-10-17 19:32:53,998: . /| . // o\ . || .) lichess-bot 1.1.5 . //__\ . )___( Play on Lichess with a bot

but after making a move, the engine does not respond. and it does respond in arenna. I Have tried to wrap the Jar file with EXE (with launch4j) and still -> worked in arenna, but not in lichess-bot.py. when I am trying to use other EXE engines -> it works beautifly, so I know the problem is not the config.yml Am I Missing something? I am running the program on windows machine, with python 3.7.9.

Thanks!

I get into the same issue with a C engine on macOS (works in local chess UIs, but not with lichess.bot.py).

I forgot to share my solution to the problem (might not work for you, but worth trying) The uci command "movetime" I accidently parsed as "moveTime" with capital T. for some reason in arenna GUI it still works, but in lichess-bot.py it didn't. once I changed it from "moveTime" to "movettime" lichess worked like a charm. @MathPlayer Don't know if it's the same problem that happens to you, but worth checking out

A different problem for me since my engine is using CECP (a.k.a Xboard/Winboard) as a protocol, but it's good to check out if there are such issues with mine as well. I guess this issue can be closed then since you found the problem in your engine's code, right?

yep it was issue in my engine not in the lichess-bot code
