ArrayList does the same. I tried using Vector and got a wierder message

what container class for a simple list with add() and size() can i use?

vector is the only container class currently supported. i can't say it's thoroughly tested, but i have tried it before and made it work. that's odd about the missing Object class. i'm not sure why that would happen. i'll try to look into this.

Thanks. I just went ahead and implemented my own List class. Just thought it was odd because HashMap worked for me with no problems.

Have a working bot now! Love the game! FEAR THE DEFENDERS!

that's very interesting, HashMap worked for you under the non-native mode? i didn't think that worked yet =/

i'll look out for defender =)

adum

Oops, looks like I should have tested my bot non-natively before I submitted it.

Edit: Changing my Vector to a HashMap seems to have made it less broken. Now I just have a null non-null error.

I really wonder how you made the Vector class work! I always get a crash (only in non-native mode). Are there any tricks which I have to know? Should I avoid the Vector class because of instability anyway?

When I add the following to e.g. Genghis:
class inner {
int x;
}
public java.util.Vector<inner> vecTest = new java.util.Vector<inner>();

Then I get the crash below, which looks very similar to what MerickOWA first reported

Hoping to upload a bot soon...
