Hmm. That's some sort of bad request coming through. What sort of stuff are you seeing in the console before that happens? Are you running a server locally and did you connect successfully?

What version do you have installed?

It happens no matter if I git clone https://github.com/dramamine/Pokemon-Showdown.git or https://github.com/zarel/Pokemon-Showdown.git to use as the server.

Can you make sure you're using 0.11.4 ? "npm install leftovers-again" should get you this version.

So I opened up Git Bash in the folder I initially installed leftovers-again and used the command "npm install leftovers-again" but nothing changed when using "npm start -- --opponent=randumb "

rokaHakor commented 6 years ago

Also while following the Getting Started guide I saw that the generate.js file and scripts folder was moved to the node_modules/leftovers-again/ folder not node_modules/leftovers-again/src/

dramamine commented 6 years ago

OK, I see what the problem is. I fixed this in the latest version, can you install 0.11.5?

rokaHakor commented 6 years ago

Looks like it is working now however when I have it play against another bot it freezes/stops working after 10 turns. It does nothing after the 10th turn no matter how long I wait.

rokaHakor commented 6 years ago

Thank you so much for making this by the way. I love playing Showdown and learning to program. I want to learn to create machine learning algorithms and I think Pokemon is a great game where machine learning could shine.

dramamine commented 6 years ago

Hmm, I'm not able to repro the "ending after 8 turns" issue, are you getting it consistently? I just ran some battles btwn stabby and randumb, and they went fine WINS: ✓✓✓✓✓X✓✓✓X✓XXX✓ KOs: 6-2 6-5 6-5 6-3 6-2 5-6 6-4 6-5 6-3 2-6 6-5 4-6 2-6 5-6 6-4

To get more debug info, you could run the command with "--loglevel=5" - probably when it crashes out, it'll have some reason for it, like "can't do this move" or something; ex. if a bot tries to do a move but it's not allowed for some reason. I haven't done a lot of testing on Windows so I hope it's not a Windows-specific issue.

I agree with you about machine learning :) hope to see people trying that someday!

rokaHakor commented 6 years ago

Yeah it looks like it is a Windows issue since I'm not having the problem using an Ubuntu vps.
