This just came up on Discord: the "cycling" OFF states in LifeSuper don't seem to cycle any more --

Code: Select all

x = 10, y = 6, rule = LifeSuper
10T$T8.T$T8.V$T8.V$R8.V$8R2V!

(At least, I was pretty sure one of our test patterns included some of this behavior, though not this exact pattern of course.)

Fixed. The issue was that with only OFF states in the pattern LifeViewer stopped calculating future generations since there are no live states.

Ha, nice! Was this a response to the New Colorful Game of Life Simulator?

(And are there any new secret keyboard controls yet, for changing the camera angle in the third dimension? I see that the arrow keys and < and > still work for the usual ANGLE and panning changes.)

It seems to work fine with different themes, and even in rainbow mode with multiple layers.

It's been planned for a long time but that was certainly a catalyst. I downloaded the simulator and it is very pretty (especially with the lighting models used). However it's also very slow when you increase the grid size a little bit.

For LifeViewer the only secret key for now is ; which toggles the "3D" projection on and off. More to follow as I get time.

Okay, here goes for a better spec for recursive pattern descriptions. We can currently do

Code: Select all

x = 1, y = 1, rule = B3/S23
!
[[ RLE eater o$3o$3bo$2b2o!
RLE herschel 2bo$obo$3o$o!
RLE halfgun 39b2o76b2o$39bo24b2o51b2o$40b3o6b2o13bo17b2o$2b2ob2o35bo6b2o11bobo17bo$2bo3bo55b2o19bo$3b3o76b2o$91b2o$3b3o84bobo$2bo3bo84bo$2b2ob2o110b2o$31b2o83bo2bo$31b2o46b2o36b2o$79b2o29b2o$110b2o$3bo$b3o$o$2o32b2o$35bo$

PASTE halfgun
PASTE halfgun 159 -3 FLIP
PASTE herschel 61 11
PASTE eater 87 -25
STEP 5 AUTOSTART ]]

But now we want to be able to define "halfgun", let's say as

Code: Select all

x = 1, y = 1, rule = B3/S23
!
#C halfgun definition
[[ RLE herscheltransmitter 2b2ob2o$2bo3bo$3b3o2$3b3o$2bo3bo$2b2ob2o5$3bo$b3o$o$2o2$15b2o$15bo$16b3o$18bo!
RLE fx153 25b2o$2o24bo$bo13b2o6b3o$bobo11b2o6bo$2b2o6$33b2o$33b2o6$30b2o$30bo$11b2o3b2o13b3o$12bo3bo16bo$9b3o5b3o$9bo9bo!

PASTE herscheltransmitter
PASTE fx153 65 -3 FLIPX
PASTE herschelreceiver 79 -3 ]]

But then those pieces in turn can be split up into their component parts, e.g.,

Code: Select all

x = 1, y = 1, rule = B3/S23
!
#C herscheltransmitter definition
[[ RLE deadsparkcoil 2ob2o$o3bo$b3o2$b3o$o3bo$2ob2o!
RLE eater o$3o$3bo$2b2o!
PASTE deadsparkcoil
PASTE eater 1 11 FLIPX
PASTE eater 16 19 FLIP ]]

Now there's a duplicate definition of "eater" between these three chunks, and we don't really want to do any but the three PASTE operations in the first chunk. So let's combine all these, something like this:

Code: Select all

x = 1, y = 1, rule = B3/S23
!
[[ RLE fx153 25b2o$2o24bo$bo13b2o6b3o$bobo11b2o6bo$2b2o6$33b2o$33b2o6$30b2o$30bo$11b2o3b2o13b3o$12bo3bo16bo$9b3o5b3o$9bo9bo!
RLE herschelreceiver 38b2o$38b2o$3b2o$3bo$4bo$3b2o$12b2o$11bobo$12bo$38b2o$37bo2bo$2o36b2o$2o29b2o$31b2o7$44b2o$44b2o$40b2o$40bobo$42bo$42b2o$29b2o$29b2o3$27b2o$27b2o!
RLE eater o$3o$3bo$2b2o!
RLE herschel 2bo$obo$3o$o!
DEF herscheltransmitter deadsparkcoil UNION eater 1 1 FLIPX UNION eater 16 19 FLIP DELTA 2 0
DEF halfgun herscheltransmitter UNION fx153 65 -3 FLIPX UNION herschelreceiver 79 -3 DELTA 0 3
DEF p1092gun halfgun UNION halfgun 159 -3 FLIP UNION herschel 61 11 UNION eater 87 -25
PASTE p1092gun
STEP 5 AUTOSTART ]]

I've added new DEF and UNION and DELTA keywords, but these are just placeholders showing where the new functionality is needed. DEF could probably be just the old RLE command. The DELTA command isn't absolutely needed, but it would be nice to have the option to build a combined pattern, then apply a transformation to the whole pattern -- instead of applying individual transformations to each of the component parts.

An equivalent would be

DEF herscheltransmittertemp deadsparkcoil UNION eater 1 1 FLIPX UNION eater 16 19 FLIP
DEF herscheltransmitter herscheltransmittertemp 2 0

-- there just needs to be room for the subpattern after the last UNION to either have following translation/transformation parameters, or to not have any such parameters.

Posted: **November 23rd, 2021, 5:25 pm**

That was enough for one post, so here's the other item I mentioned via chat.

Very often you want to make slight changes to a combined pattern -- use an alternate form of some subpattern, weld pieces together, etc. That could be something like this -- see the third line from the end:

Code: Select all

x = 1, y = 1, rule = B3/S23
!
[[ RLE fx153 25b2o$2o24bo$bo13b2o6b3o$bobo11b2o6bo$2b2o6$33b2o$33b2o6$30b2o$30bo$11b2o3b2o13b3o$12bo3bo16bo$9b3o5b3o$9bo9bo!
RLE herschelreceiver 38b2o$38b2o$3b2o$3bo$4bo$3b2o$12b2o$11bobo$12bo$38b2o$37bo2bo$2o36b2o$2o29b2o$31b2o7$44b2o$44b2o$40b2o$40bobo$42bo$42b2o$29b2o$29b2o3$27b2o$27b2o!
RLE eater o$3o$3bo$2b2o!
RLE herschel 2bo$obo$3o$o!
DEF herscheltransmitter deadsparkcoil UNION eater 1 1 FLIPX UNION eater 16 19 FLIP DELTA 2 0
DEF halfgun herscheltransmitter UNION fx153 65 -3 FLIPX UNION herschelreceiver 79 -3 DELTA 0 3
DEF p1092gun halfgun UNION halfgun 159 -3 FLIP UNION eater 87 -25 XOR 3b2o$2bo2bo$o2b2o$obo$2o! 114 8

PASTE p1092gun
STEP 5 AUTOSTART ]]

The "XOR 3b2o$2bo2bo$o2b2o$obo$2o! 114 8" is supposed to overlap the beehive inside "halfgun", which is really the beehive inside "herschelreceiver" -- the beehive cells should turn off while at the same time the glider cells turn on.

As before, there are lots of other syntax options. This method produces the required "XOR patch" functionality by making XOR into an alternate command along the same lines as UNION.
