@Jona Hi, the video looks cool!

1. Sorry, I don't know what you mean by "how to make "shift" work again". I hope you'll find a solution.

2. Yes, returning a 2 dimensional table will cause a patch to crash since it doesn't know how to convert it to a pd list. Why do you need to return the table? If you're trying to write the table to a pd array, I think you can do it internally using a pd.Array() class without returning the table.

3. I'm not sure what would be the best way to save and recall a 2-dimensional lua table in pd. Even if you have a 2-dimensional table, you can write the data to 1 dimensional [array] and read back from it if your table has a fixed size. (e.g. 32x32 2-dimensional array can become 1024 1-dimensional array) And I don't know what you mean by flatten/deflatten the lua table.

4. I checked your patch and you are sending [invert( message into the "ofelia d -c11 -k $0-Invert" object which does not call ofelia.bang() function but ofelia.invert() function. So you should either send "bang" message to an object or rename the function to "ofelia.invert()"

Hi @Cuinjune, thank you for the feedback.

1. Happily "Shift" works again. I meant the functions that shift the grid one step into one direction. It did not work anymore because i needed to adjust the functions to the 2 dimensional table.
2. You are right, I do not need to return the table, i think your suggestion to do that internally with pd.Array() is the solution. Will try that tonight.
3. It is fine for me to write a 2-dimensional lua table to a 1 dimensional [array]. With "flatten" I meant to make a 1 dimensional table out of a 2 dimensional table. With "deflatten" I meant to make a 2 dimensional table out of a 1 dimensional table. I think I did not found the right terms for that.
4. Thanks. That was my mistake, it works again. I still think there is some strange behaviour under certain conditions with sending bangs into ofelia objects, but I am not sure anymore. I will check that and post a minimal patch if I still find that behaviour.

I would love to play around with these ideas, but none of the above patches work with Ofelia v3.1.0.
I tried to update the file ofelia-2-gridx.pd and made some small changes in order to make it work, but it doesn't seem to really work as expected; it doesn't show any graphics besides the background... I added some question marks where I'm not sure if I did the right thing.
Could you please take a look? Also, this is the first time for me uploading something here, so please excuse me, if I'm doing something silly 1544816749521-ofelia2_gridx-new.pd

@Shaker I already updated the patch, you can find it in another thread (third post): https://forum.pdpatchrepo.info/topic/11826/conways-game-of-life-made-with-ofelia/2 (you need to set generations to 1 to get midi output, because that patch is "optimized" for the game of life)
