Spring RTS Engine

My AI deploys and runs without crashing. I want to utilize a library in an external JAR file (signalr-client-sdk.jar). I've placed the JAR file in the /jlib directory under my AI, alongside vecmath.jar and JavaOO-AIWrapper.jar etc. I add a line of code in my AI's init method instantiating an instance of a class from the JAR file.

My code compiles fine in Netbeans with this instantiation line. But it crashes my AI in Spring. I think it's not seeing my JAR file. How do I make it aware of it? Here's my infolog.txt snippet:

Code: Select all

Note, I'm using the 101.0.1-373-g9d13eb6 development build as it fixed an issue with loading Java AI's.

It turns out that while my project was building successfully, the signalr-client-sdk.jar I was calling needed two additional JARs (Google's JSON library and Java Web Sockets library). This only became apparent at runtime once I made a standalone Java executable tried to use signalr-client-sdk.jar. My problem is solved, but perhaps this would be easier if the AI interface could capture this error better?

what do you mean with "this"?

I mean debugging to figure out what was wrong would be easier if it was able to give a more descriptive error message.

there seems to be no easy way to print such info to infolog.txt, needs some work on the interface:
