lifeviewer bug

Couple closely related behaviors:

1) Open the viewer for this pattern, input Ctrl+A, see that the selection area is shifted down and right from the correct area

Code: Select all

2) Copy this pattern into the custom pattern box on https://conwaylife.com/, change the rule by typing the in the text box to Life (instead of LifeHistory, click Update LifeViewer, Ctrl+A, see similar selection displacement

Try running it until you get past generation 63, then use the “step back” button to get back to 63

Sadly I don’t think I can reproduce it

I had the same thing happen some time in the mid-50s (just after the second LWSS formed). I tried to see how it formed, so I tried to back up, and it just vanished. When I tried to reproduce it to see exactly when, it then worked correctly

I can't reproduce it either. If you find a way please let me know!

Try running until after the first LWSS forms, then click previous generation twice rapidly. The second signal might disappear.

I tried selecting the middle portion with a 2x1 selection, it turns out the selection is shifted one over.

Go to somewhere in the middle of the big long barge thing and remove at least 4 cells (a tub shape) to "break" the barge. Do NOT touch any of the other trail cells. Now run the pattern until the crab hits the border and disappears. The broken off section disappears too, even though it is only connected by trail cells. AFAIK these trail cells shouldn't count as "connecting" because it's only a LifeViewer-generated visualization (it's not LifeHistory).

This is a feature, not a bug. The reason the rest of the barge gets deleted is because it deletes live cells withing a certain range of other live cells to be deleted. This is due to patterns which would otherwise make a mess when hitting the boundary. If you don't like this, try something like this:

Code: Select all

x = 20, y = 18, rule = B3/S23

I tried erasing some of the cells here, but they turned into dead deep blue cells instead:

EDIT:
The reason of making this rule is to stack patterns together in smaller bounding box.
Pentadecathlon stack 2 blinkers (p30):

I don't know of a better place to put this, but at the bottom of the page in lazyslug.com, "Anything copied to the clipbboard will also appear here." has an erroneous b.

If you select one of the blocks and then change the rule, the other block will dissappear.

Code: Select all

x = 11, y = 2, rule = B3/S23
2o7b2o$2o7b2o!

[b-engine]

Select this block and nudge it, then LifeViewer will say there's no room to nudge the block.

Code: Select all

x = 2, y = 2, rule = R2,C2,S4-6,B5-6:T10,10
2o$2o!

This don't happen in R1 HROT rule.

Code: Select all

x = 2, y = 2, rule = R1,C2,S2-3,B3:T10,10
2o$2o!

[rowett]

Code: Select all

x = 11, y = 2, rule = B3/S23
2o7b2o$2o7b2o!

This is by design. If there is a selection when you change rule then the new pattern only contains the cells in the selection.

Select this block and nudge it, then LifeViewer will say there's no room to nudge the block.

Serious bug: paste any RLE into the box on the LifeViewer page (https://lazyslug.com), and click the view button; it doesn't respond when it should start displaying the pattern

LifeViewer identifies that 1-cell on-off has both active rotor cells, volatility, temperature and heat of 0 (which is impossible for any oscillator) even through it's period and mod is 2.

I don't know if it's the most recent android or what but Lifeviewer is extremely flickery and barely functional on mobile for me.

I don't know if it's the most recent android or what but Lifeviewer is extremely flickery and barely functional on mobile for me.

Please let me know which version of Android you are running. There haven't been any significant changes to LifeViewer recently.

Anyone else on Android experiencing this issue?
