Howdy everyone! (and a question)

Hi, I just got DarwinBots. I've been a big fan of evolution simulators for years, but most of that was back when I was mainly a Mac user (there are a lot more alife programs out there for Mac it seems). DarwinBots has re-awakened my interest, as it seems to encapsulate everything I've wished for in an alife program, but I'm having a problem.

I downloaded the main 2.1 installer, as well as the 2.37.4 update. The main installation was self-explanatory, and although there are no install notes on the updater, I assumed you simply extract it on top of the main install, and run the new executable.

The program starts normally, and says 2.37 in the title bar, but the moment I open the New Simulation window, or click the "start" or "pause" buttons, or do pretty much anything, the title bar changes to read 2.36. My simulations invariably end with the overflow error that people are reporting, the one that is apparently fixed with 2.37.4. That further adds to my confusion, thus this forum post. What the heck am I doing wrong? I tried re-installing from scratch, but no difference.

Thanks for any help!

Oh, and I don't know if this is related, but the light intensity controls for the pond mode aren't working for me. Before applying the 2.37.4 patch, I could change those values and see the difference in the light through the pond (really cool feature I think!), but after the update the feature seems broken.

Numsgil:
Hmm... have you checked the field value in the veggy nrg feeding place?

In past versions, this was something similar but different, and values of 100000 were common.  In newer versions, this now represents the nrg each veggy gets, and so needs to be, like, 4.

That should clear it up.  I'm not sure what the title bar issue is, but it's probably just me forgetting to change the caption at some point in the program.

Yossarian:
Thanks! I noticed the nrg figure before. In the older version, I remember it being some crazy-high number, then that it had been lowered significantly in the upgrade. However, after reading your post I went and looked, and it was set to 500,000. I lowered it to 4 and I have a sim going right now. The overflow seems fixed; this is by far the longest I've had it running without an error.

It wasn't until after I posted last night that I noticed elsewhere in the forum that 2.4 is going to be released in a week or so, and as a main install. Almost made all this a moot point, except how could I wait a week to use the program? :D

On that note, let me just say that this is the finest alife program I've ever used, and I'm conscious of the fact that I've barely even broken the surface of it (hell, I'd only had a sim running for seconds, and I already knew that I had struck gold). The only time I've ever been interested in learning how to program was specifically so I could combine my favorite features of all my other alife programs (notably Evolv-o-Matic for the Mac, which until this program was the only one I'd found that offered the sun as a variable). This is the program that I was looking for all that time. So kudos to everyone involved, both the coders and the people who actively use it and keep it alive. I couldn't believe my eyes when I found an honest-to-god active forum about an evolution sim!  :cheers:

Thanks B)

I think we're all amazed how far DB has come :)  :D  :lol:

I remember feeling the same way when I stumbled upon the old forum, WoW.
