To take a look you need a smallish pattern in Golly (Layer 0), e.g.
then Add Layer (1) and from that layer open which will present a dialog in which you can enter a target generation. I'd suggest keeping that number under or not much over 100 and then hitting return to let it run past generation 128. If you optionally enter an initial delay it will automatically start generating when that delay is done. It imitates the handling of a core subset of Golly's keyboard shortcuts but becomes painfully slow once the generated pattern becomes fairly large.
Code: Select all
x = 15, y = 15, rule = B1357/S02468
If you want to keep playing, you will need to open that zip outside Golly and move pattern_breeder.pl to Golly/Scripts/Perl, then you can happily play with arbitrary neighbourhoods which are defined by the pattern in Layer 1, keeping in mind that generation time is proportional to the number of live cells in your chosen neighbourhood.
