Problem with my Nostoc bot

[Testlund]

Can somebody tell me why this bot refuses to multiply? It has worked before so I take it something changed in later drops so the DNA isn't compatible. Everything else seems to work.

I found that the program changes the DNA after I start a sim! It puts 0's in front of some genes. This is what the dna looks like in the program:

 0 *.nrg 10000 >
 0 50 .repro store
 100 .aimright store

0s means the program had no idea what command you were trying to use.  It's the program's way of saying "no comprende".  If you write a bot, always look at its DNA in the program and search for 0s, because they're usually typos on your part.

In your case, your cond's were capitalized.  It needs to be cond, not Cond.  Likewise Start isn't a valid command.

I've added code a while back so that sysvars are case insensitive, but I never did it for flow and other commands.  I'll add that the next drop to avoid this kind of thing in the future...

I would never have guessed, but now that you mensioned it I think I remember you posted about it some time ago.
