Is this reaction between a LWSS and blinker already discovered?

Code: Select all

x = 8, y = 8, rule = 23/3

It can also be made into an oscillator:

Here is a loaf-turning reaction:

Another glider following on the same path turns it again: (!)

It's a shame that the sparks are so protrusive. Otherwise, you could have a self-activating eater3!

[knightlife]

A two glider slow salvo moves a beehive 7 cells vertically:

x = 14, y = 14, rule = B3/S23
bo$2bo$3o4$12bo$13bo$11b3o3$11b2o$10bo2bo$11b2o!


One glider moves a loaf without turning it:

x = 7, y = 9, rule = B3/S23
bo$2bo$3o3$4b2o$3bo2bo$4bobo$5bo!

(Edit)
Oops! see next post...

[PM 2Ring]

This reaction shifts the loaf by (-1, 3) without turning it. This reaction is slightly faster than the turning reaction, and takes up less space. But by itself it's not much use for constructing fixed oscillators. It might be useful in a rake / puffer construction, though. Or when combined with Extrementhusiast's turning reaction.

Code: Select all

x = 9, y = 8, rule = B3/S23
6b2o$5bo2bo$5bobo$6bo2$3o$2bo$bo!

Edit. Ninja'd by knightlife. Here's both reactions together, which shift the loaf by (2,2).

Code: Select all

x = 19, y = 18, rule = B3/S23
17bo$16bo$16b3o8$6b2o$5bo2bo$5bobo$6bo2$3o$2bo$bo!

Is there a single glider reaction which flips a loaf? I've seen loaf flipping reactions in static constructions, but they have other still lifes around the loaf, which reset it to its original position & orientation.

[knightlife]

Move a block and make a LWSS at the same time:

Code: Select all

x = 10, y = 19, rule = B3/S23
bo$2b2o$b2o6$bo$2bo$3o2$8bo$9bo$7b3o3$8b2o$8b2o!

This could be used to make a LWSS gun that moves the block back and forth while creating two LWSS streams.
A block and two gliders makes the LWSS and the third makes a new block with debris that would become a loaf.

Edit:
Hmmm, I just noticed if I advance the third glider a bit I get a pi pattern that can repeat like this:

Code: Select all

x = 64, y = 74, rule = B3/S23
60bo$60bobo$60b2o5$63bo$61b2o$62b2o2$2bo$3b2o$2b2o5$bo$2bo$3o2$50bo$

2$29bo$30bo$28b3o3$29b2o$29b2o!

Now instead of a LWSS gun, a LWSS rake can be made with puffers providing the gliders.
The pi pattern moves 2x6 every 21 generations.

[knightlife]

Unusual 2 object move I found:

Move a loaf and a boat at the same time:

Code: Select all

x = 12, y = 17, rule = B3/S23
o$b2o$2o5$9b2o$9bobo$10bo4$9bo$8bobo$7bo2bo$8b2o!

They both move but the loaf also rotates.

[calcyman]

Is there a single glider reaction which flips a loaf?

Yes, there's the following famous reaction:

Code: Select all

.*......

It's used as the mechanism behind the eater3. You can see the eater3 in the corner of my rectifier reflector, which is displayed as my avatar.

Ah, yes. That's what I was thinking of, but I've never investigated what happens to the loaf without the other parts of the eater3. Thanks, calcyman. I'll see if I can build a loaf pusher or puller using that reaction & the one posted by me & knightlife.

The following uses the loaf flipping reaction as a stable trigger for a fuse.
The reaction passes through the loaf as it flips back to its original position.

The fuse is rather useless but maybe the trigger is useful for something.
Either a LWSS or a MWSS will work to start the reaction.

[calcyman]

Either a LWSS or a MWSS will work to start the reaction.

Or a glider, obviously. With suitable modification, it can even be made to eat a HWSS:

Very few HWSS eaters are known. In fact, I only know of two different fast mechanisms:

I tried to merge eater3 with the still life you added to get a standalone HWSS eater.
So close, yet so far!

I'm guessing you tried that too.
It is awesome how the eater1 recovers from near destruction, turning into a tub=with-tail during its recovery.

Oh, yes. But, unfortunately, without any luck. Anyway, two independent HWSS eaters are already known, so there isn't much point. It would be nice to have a very elaborate HWSS eater, but the chances of merging those still lifes is probably impossible.

There is another variant of the eater3, which might fit better:

Code: Select all

It is awesome how the eater1 recovers from near destruction, turning into a tub-with-tail during its recovery.

It's possible to get a synthesis out of this:

The HWSS eater could have been discovered in a random soup since it is just a glider and a hive collision.
So, a three glider synthesis of a HWSS eater:

Code: Select all

x = 27, y = 11, rule = B3/S23
19bo$20b2o$19b2o$2b2o$o4bo$6bo15bo$o5bo13bobo$b6o14b2o$24bo$24bobo$24b

It's cool how it resynthesizes itself.

[calcyman]

The HWSS eater could have been discovered in a random soup since it is just a glider and a hive collision.

A single LWSS can return the HWSS eater to its 'seed' beehive. I'll leave this as an exercise for the reader.


For reference, this mechanism involving the conversion of the HWSS eater to a beehive and vice-versa is called the honeybit reaction.

It's cool how it resynthesizes itself.

Superbly elegant, yet completely unrecognised. No-one replied to Brice's e-mail announcing the mechanism, and this is the first time that it's been published online.

[PM 2Ring]

I'll see if I can build a loaf pusher or puller using that reaction & the one posted by me & knightlife.

Well, I can push a loaf down a diagonal, but it requires gliders coming from 3 directions, which is not very useful when trying to make a pusher gun. I've briefly tried to do it using rakes, but I need a rake (or convoy of rakes) that can send gliders down paths two cells apart.
