Is there any way to stop [[KILLGLIDERS]] from killing the glider that hits the LWSS and becomes a block in the twin hat modification soup?
Please post the pattern (or a link to it).

For me, the first pattern evolves into an r-pentomino after 2 generations, as it should. I don't think KILLGLIDERS is supposed to kill a glider that's about to interact with a spark.

I think, based on my observations, it only kills a glider that doesn't interact with anything for so many generations after the shape forms.

I think it actually deletes them when they leave the influence of the bounding diamond of the rest of the pattern. Consider, for example, this pattern, where the gliders take different lengths of time to be deleted:

Code: Select all

#C [[ KILLGLIDERS ]]
x = 43, y = 41, rule = B3/S23
20b3o20$3o37b3o3$6b2o$7b2o18b2o$6bo21b2o$27bo14$20b3o!
This ensures that deleting them doesn't change the evolution of the remaining pattern.

When you switch on [[ KILLGLIDERS ]] each glider becomes a candidate for deletion when it is at the bounding box of the pattern and escaping. It won't then be killed until the diagonal is clear. From the original soup above at T=333 you can see the southern most glider (marked in yellow) is at the south boundary of the bounding box and escaping. However its diagonal is not clear because of the south moving LWSS on the left (also marked in yellow).

Code: Select all

#C [[ KILLGLIDERS ]]
#CXRLE Gen=333
x = 70, y = 81, rule = LifeHistory

I’m getting the Slow Mo Blue Box again (hello from an iPad), and I think I have a reliable method of recreating it:
1) Tap the edge of the viewer window
2) ???
3) Profit

I think what’s happening is that the tap is causing Safari to try and select the viewer canvas, leading to a blue outline. As for why Slow Mo Blue Box Syndrome slows the viewer to a crawl, um,
Each day is a hidden opportunity, a frozen waterfall that's waiting to be realised, and one that I'll probably be ignoring

I have no idea if this is related to what you're referring to, but ever since I joined this forum, and probably before, the pattern runs at about 60% speed whenever it's in focus, no matter what. It feels like it's probably intended (the speed box turns red, and people would have noticed by now), but I have no idea why.

In addition, once a glider escapes and is destroyed by the outer bounding box limit, it will never run at 60× again for that session (it seems to be stuck at 45 or so for simple patterns, but not a constant number), even if you go back to generation 0 and reset everything.
