Golly 2.4 is now available from sourceforge:

https://sourceforge.net/projects/golly/ ... golly-2.4/

This release fixes a few bugs. In particular, the 64-bit Windows app can now use more than 4GB of hash memory. All the changes are listed here:

awesome!

When I press "Ctrl Z" to undo, I get an error message.

What message exactly? Which platform? (Windows or Linux?) Is it 100% reproducible? If so, what are the steps that cause it?

(If you're going to report a bug, please put a bit of effort into it!)

Windows 7, it happens every time, when I press Ctrl+Z using any algorithm except quicklife. When I do it in hashlife b3/s23, the message is (I get all of these messages at once):
Error from Hashlife: node out of range in readmacrocell.
Error from quicklife: cannot read macrocell format.
Error from generations: missing expected slash in generations rule
error from JvN:This algorithm only supports these rules: JvN20, Nobili32, Hutton32
error from RuleTable: Failed to open file: (insert file name for a rule table)
error from rule tree: parse error in macrocell format.

For the other non-quick algorithms, the error from the algorithm I am using is "cell state values too high for this algorithm", while all the other errors are the same as what I wrote above.

Ah, it sounds like you are loading a .mc file that was saved with timeline data from an older Golly version. That was one of the bugs we fixed in 2.4. You'll probably have to re-create that .mc file with 2.4.

If I'm wrong about this then I'll need more clues:

Did you download Golly 2.4 from sourceforge? If so, did you get the 32-bit or 64-bit version?
Please describe the *exact* steps leading up to the error message from the time you start up Golly (ie. which algo you are using, which rule, which file you load, etc).

Very strange. Now the undo button seems to be working fine, but .mc files do not load at all (they give me the same error messages as I already gave). This includes both .mc files I previously created, and ones in the hashlife folder included with 2.4. I'm not sure how to recreate them in version 2.4, since I can't open them to begin with.

The exact steps were:
I downloaded the 64-bit version of golly, clicked "save file." Then I opened the compressed folder (I did NOT extract all), then I copied the "golly 2.4" folder to the top of my downloads folder. Then I went into the golly 2.3 folder and copied all the rules and scripts into the correct 2.4 folders (hitting "don't copy" for duplicates), then I copied the 2.3 folder containing all the patterns I saved which were not included in the default pattern collection. Then I opened golly.

My most heartfelt apologies; I cleaned up some warnings and somehow
this happened. I have not yet tracked down the specific reason, but I
have found that adding some printf's, or additional initializations, fixes
the problem. I have put new 64-bit Windows builds at

http://tomas.rokicki.com/golly-2.4-win64-5.zip

If anyone with access to a Win 64 system would try it out, I would be
most grateful.

The problem does not show up on 64-bit Linux or 64-bit Mac, and
since adding a single printf() fixes the problem, it *does* look like a
compiler problem.

Thank you for your patience.

Tom's confident he has fixed the bug so I've uploaded his new 64-bit Win build to sourceforge.

Thanks for your bug report!

It is now working, thanks!

Im new on the forums, i heard of the game of life and I like it. I was playing around and I have a question:

Theres a way of placing walls for the cells?

thanks

EDIT: I discovered yhe bounded grids on golly and I dont know how to make it any help?

Hi Toad4! Welcome!

EDIT: I discovered yhe bounded grids on golly and I dont know how to make it any help?

For bounded grids, try appending ":P200,100" to the rulestring (so in case of Life, you'd use either "B3/S23:P200,100" or "Life:P200,100"). This gets you a bounded grid with width 200 and height 100; you can set different numbers here too (use 0 for unlimited height or width while keeping the other one limited).

It's also possible to create custom rules with "wall cells". For example, Extended Life as described in this topic has grey permadead cells (state 5) that work as walls. A small demo—

Ok, thanks but where I need to put the code?

If you mean where do you type in rules like "B3/S23:P200,100", do it in the Set Rule dialog (at the bottom of the Control menu).

I mean the code that appears on the extended life post, but the other helped me. thanks

EDIT: problem solved. I first thought that the rules where made on python, but was in C++ now im running extended life. thanks
