### Re: How about a unidimensional spaceship?

Here are some proof-of-concept salvos 1, 2, and 3 (plus glider source) that can be used to automatically build a 6c/13 wick, and that can be toggled on and off when it rams into strategically placed blocks:

Code: Select all

``````#C Bistable slide gun salvos for building a 6c/13 wick.
#C These examples aren't very efficient, but they serve as a proof of concept.
#C In order to build a 6c/13 wick, the salvos need to be fired repeatedly in
#C numerical order, 1 2 3 1 2 3 1 2 3 etc.
#C I was too lazy to get nice tidy big lettering for the labels so they're hand-drawn

This solution looks pretty ugly, needing roughly 20 xWSS on each side of the center axis per period. But it shows that this kind of approach to rebuilding the wick is an option available to us. I've attached a quick and dirty demo of this system, showing that the toggle functionality does work. This idea could in theory be used for more complex wicks to build like 2c/3, though the whole thing would be quite a bit more complex. I fully expect that the version I've posted here won't be the final version making it into the spaceship, even if it does use an automatic wick extender setup like this, just because it's so inefficient and it also builds a wick slower than c/2.

Inefficient proof of concept that a wick can be rebuilt automatically, with the information for the start and end points of each section ultimately coming from the original wick's debris itself.

### Re: How about a unidimensional spaceship?

Here are wick transitions:
Normal wick -> pre-pulsar -> t tetromino -> t wick (6c/13 *2) -> queen bee -> normal wick.
All the transitions are clean.

Code: Select all

``````x = 209, y = 1, rule = LifeSuper

I don't know if these are the simplest normal->t and t->normal transitions, I've found them while studying various wick reactions.

Also, I've found an another method of supposedly universal initial construction. The concept is to fire a glider far into the sky, wait for some time, shoot it down with vertical LWSS producing another glider travelling down (the wick stops after emitting the LWSS). That glider then collides with the middle-point and ignites two wicks travelling away from each other. These wick fire backwards LWSSs which collide to produce explosions at various points. These explosions then are catalyzed by dirty wick debris to produce something.
Camera operator work is hard...

I think this method is more convoluted than single-channel HWSS one, but it may happen to be useful. It is shorter for the same number of XWSSs, so it may be more efficient. These methods can even be combined, since the wick has to travel at c/2 to catch the glider with the LWSS, and it does so naturally while constructing HWSS stream. There is also a problem of cleaning up glider-LWSS explosion, but that can be done with just a few gliders.

How did you find the vertical LWSS producing reaction? It may be beneficial if we have more downward glider channels.
Still drifting.

That was the reaction that happened VERY often in random blinker soups. I even had to explicitly forbid [2,8] spacing at the beginning so that these reactions won't clutter up results.
Also, gliders from this reaction are very expensive. You have to align fuse at two points of space-time, and you have to clean up the debris from the reaction.

There is also this clean reaction:

Code: Select all

``````x = 54, y = 42, rule = LifeSuper

``````
But that is inaccessible right now, as 1) input glider lanes are too close and 2) the LWSS is of wrong parity.
