Sorry about the delay, Alegend, but I hope this helps.
Constructing a p30 LWSS gun - a short tutorial.
Introduction
Most modern Life programs let you use multiple layers. This is very
handy when constructing Life patterns from multiple components. I
generally use (at least) two layers, one layer is used for the main
construction site, and the second layer is used to hold the various
components. A third layer can come in handy for loading in extra
components or testing small reactions.
When working with glider-based periodic patterns, I find it useful to
set the hashing step size to 4 (the glider period) and the non-hashing
step size to the gun period. We are using p30 guns in this exercise, so
let's set the non-hashing step size to 30.
Construction
To build a p30 LWSS gun we need the glider synthesis for a LWSS and
a p30 glider gun. Let's use layer 0 as the construction layer & use
layer 1 for our components. Load each required component in layer 0
then copy it to layer 1, making sure there's plenty of room around our
components.
Copy the LWSS reaction back to layer 0. Layer 0 should now look like
this:
Next, we'll add a gun to generate the top glider.
Go to layer 1 & rotate / flip the gun into the correct orientation,
so the glider stream is going in the desired direction. Note that due
to glider symmetry that there are two ways to do this, for example:
Run the pattern for a few cycles of 30, until it has produced 3 or 4
gliders. Single step the pattern if necessary to get the last glider
into the correct phase. Copy this gun (& its gliders) and paste them
into layer 0 so that the last glider is aligned with the top glider
in the synthesis, like this:
Next, we'll add a gun to generate the leftmost glider.
Go back to layer 1 & flip the gun vertically. Copy & paste into layer 0
so that the last glider is aligned with the leftmost glider, like this:
Finally, we'll add a gun to generate the rightmost glider.
Go back to layer 1 & flip the gun vertically and horizontally. Advance
it by one step to bring the last glider into the correct phase. Copy &
paste into layer 0 so that the last glider is aligned with the
rightmost glider, like this:
Our LWSS is complete! We can improve it by shortening the various
glider streams. We may also need to change the glider gun orientations
to leave enough room for the reaction and so that the LWSS doesn't
crash into our glider guns. Notice that by advancing a glider gun by
multiples of 4 steps the last glider stays in the same phase. This is
very useful when trying to make glider circuits as compact as possible.
