Instructions on starting microRTS

[douglasrizzo]

After starting my own agent, which inherits from pyrts.server.Server, how should I start microRTS?

I changed launch_mode=SERVER and AI1=ai.socket.SocketAI in config.properties and started rts.units.MicroRTS, but I get a java.net.BindException: Address already in use from MicroRTS.

I have figured it out. I should start MicroRTS in client mode, not server mode.

OK, it seems like I need some help after all. I tried running the examples and then starting MicroRTS in Client mode. This is the output of running one of the python-microRTS examples (I applied the pull request which fixes a bug after gameover):

The problem is that MicroRTS receives an empty JSON (in this line, the value of the JSON variable is null, which crashes MicroRTS). It seems like python-microRTS ends the game before sending any actions.

This happens with both examples. Any tips on solving it?

[douglasrizzo]

The problem is that python-microRTS detects a gameover when the first JSON message received from MicroRTS starts with anything different that getAction. This happens in these lines.

But, as you can see from my previous message, when a game begins, a message is sent that begins with budget. This prompts python-microRTS to end the game. I'll try to find a fix for this tomorrow.

Hi Douglas, I do not maintain the python-microRTS side, but if there is anything I can do on the Java microRTS to address this issue, just let me know. If python-microRTS does not like those budget messages, maybe I can add some configuration options to the SocketAIs on the Java side to skip them on request. Just let me know.

Hello @santiontanon , I don't think there is any need to change the messages in microrts, as I was just able to find and fix the error I mention here in #3. Thank you for making yourself available.

ok! no problem! I hope your pull request is accepted, as it can be useful for many more people! :)
