#1 in melee!418:17, 14 February 2019



I had left my meleerumble client running and I got this error from ScalarR:

Exception: java.lang.NoClassDefFoundError thrown from the UncaughtExceptionHandler in thread "aaa.r.ScalarR 0.005g.047"

Anyway, after searching through the terminal, I found that Garm also gave the same error.

Please let me know if this is an issue with the robots or my meleerumble client(in which case I will be removing Golem to minimize the damage caused).

Which version of java are you using? (e.g. java -version)

and obviously all robots listed there can run, so it has to be something with your configuration.

Xor (talk)02:52, 27 August 2020

I am using 11.0.5

I'll be removing the robot from the rumble.

Dsekercioglu (talk)08:35, 27 August 2020

Please try with Java 8. Java 9 and successive versions like java 11 has incompatible changes which may be the root cause of ClassNoDefFound error

We recently moved to java 11, but it’s never tested for old robots.

Btw, are you using OpenJDK or orcale jdk?

Xor (talk)11:38, 27 August 2020

I use oracle jdk currently.

Climbing . . .

Congrats on your recent updates, only 1.00 point left to become first in 1-on-1 too ! Just out of curiosity I compared ScalarR with ScalarN, and I noticed one thing: ScalarR is much better against every rammer in the field. Every rammer except one: GrubbmThree . . . Why ??

GrubbmGait (talk)13:23, 19 August 2020

Thanks for noticing ;) Despite the names, ScalarR and ScalarN has nothing in common. And ScalarN is worse against all rammers simply because its flattener threshold is very bad ;)

ScalarR solved this by not using a flattener at all ;)

And... I have to say that GrubbmThree is an excellent rammer, and was one of my favorite bot to try with ;)

#1 in melee!

ScalarR is now ranked #1 in the MeleeRumble. Congratulations, Xor!

After 1 year, 3 months, and 22 days, we have a new champion.

It's nice to see the standard for melee bots has been pushed to new heights. I hope this will spark renewed interest in Robocode.

Once again, congratulations!

Thanks! It's also awesome to see every time we thought there are limits, it's pushed further and further...

Xor (talk)04:49, 13 February 2019

Congratulations!!! That is quite huge to see that the bar is high but yet could be lifted even higher.

Beaming (talk)20:05, 13 February 2019

Congratulations! Maybe this will motivate me to work with Java again and implement the multi-wave surfing for Neuromancer that I've wanted to do for so long. Neuromancer could also improve the strength against strong boys at the end a lot, let's get this competition going!

Skilgannon (talk)17:51, 14 February 2019

Great! It will be fun to see how we can push the limit of melee surfing to.
