lifeviewer bug

[H. H. P. M. P. Cole]

Have a try copy-pasting this pattern in lazyslug.com:

If lazyslug.com correctly works it should produce a p8 oscillator in the middle (which it correctly does, on the forums' built-in viewer). However, it doesn't, and instead the soup dies out after 1 generation. Can someone please fix the bug?

Fixed, thanks for reporting!

Doesn't work for me though. What do I have to do?

LifeViewer displays Golly theme like this:

Code: Select all

x = 2, y = 2, rule = /2/3
BA$BA!
#C [[ THEME GOLLY ]]

However the actual Golly theme have red and yellow swapped (thus the gradients between them).

EDIT:
If you turn on HQ rendering & stars then you'll see this:

Please post a link to the pattern. Does it always happen? What error is provided if you click on "SHOW PATTERN ERROR"?

Probably worth pointing out that this change also affects higher-range Generations rules, which is the opposite of what Golly does (in this case it was correct before):

Code: Select all

x = 30, y = 12, rule = R2,C4,S3,B4
2$4.B.C.B$2.2A.C.C.2A$.AB2C3.2CBA$ABC7.CBA$ABC7.CBA$.AB2C3.2CBA$2.2A.
C.C.2A$4.B.C.B!
[[ THEME Golly ]]

Personally I think the Golly theme should be kept as yellow-to-red; Andrew himself has stated that red-to-yellow was a mistake and that yellow-to-red is a superior choice, particularly on a dark background.

I assume it isn't possible to have a theme default to red-to-yellow for range-1 and yellow-to-red for general-range?

The whole point of Theme Golly is to duplicate what Golly does. I also agree with Andrew which is why the Generations Theme in LifeViewer differs from Golly and is yellow-to-red.

In this case would it also be possible for the Golly Theme to display 2-state higher-range patterns in the same way (yellow instead of white)?

Code: Select all

x = 9, y = 10, rule = R5,C0,S33-57,B34-45
3b3o$b6o$b7o$8o$9o$obo2b4o$o4b4o$2o3b4o$b2o2b3o$2b4o!
[[ THEME Golly ]]

The Golly theme for higher-range rules also appears to be leaving a trail of history cells behind now, which is not the case in the actual program nor for range-1.

I don't know if this is the same pattern, but I currently observe the same behaviour for several patterns posted on the same page of the thread: viewtopic.php?p=42350#p42350
viewtopic.php?p=42370#p42370
viewtopic.php?p=42373#p42373
viewtopic.php?p=42385#p42385
viewtopic.php?p=42388#p42388
viewtopic.php?p=42399#p42399
viewtopic.php?p=42400#p42400

Clicking "Show in viewer" appears to show the pattern, but I did not check extensively if it works correctly. Clicking "Show pattern error" shows "DeadlyEnemies - Unsupported rule name".

edit: LifeViewer build 1125

Yes, done.

In [R]Investigator there're two buttons that overlaps when you select a pattern:

Code: Select all

x = 1, y = 1, rule = B3/S23Investigator
!

However it doesn't happens in [R]History and [R]Super:

Code: Select all

x = 1, y = 1, rule = B3/S23History
!

Code: Select all

x = 1, y = 1, rule = B3/S23Super
!

What does the white cells even do? The rule (Ignorance) has only 3 states and the white cells doesn't include in the cell states.

Switch the rule to Ignorance to see the white cells:

Code: Select all

x = 11, y = 3, rule = B3/S23Investigator
.A3.B3.E$A3.B3.E$3A.3B.3E!

Code: Select all

x = 11, y = 3, rule = Ignorance
.A3.B3.E$A3.B3.E$3A.3B.3E!

Also you can switch the rule to Ignorance but the "SHOW PATTERN ERROR" says that Ignorance isn't supported rule name.

The white cells are state 5 from StateInvestigator. LifeViewer doesn't know how to convert a state-5 cell into a rule with only 3 states, so it just…doesn't. (I am surprised it doesn't throw an error, though.)

When I click on the white cells it literally says it's state 5 cell.

See the bottom left corner.

Surprisingly the state 5 cells do work.

try to set this to 50x speed.
When I try it it either plays at 49x speed or 51x speed
Is this a bug or does it just not work on my MacOS Catalina?

Edit: it also seems you can't set it to 62x either

[b-engine]

You can use + and - keys to set the playback speed precisely, regardless of OS.

This is in LifeViewer help

ok then

it's just that the slider doesn't really go to 50x speed

[b-engine]

The shortcut keys are used to get around the problem. However, the problem is still in touchscreen devices.

Next time make LifeViewer bug reports like this in LifeViewer bugs thread.

Fixed, thanks. You'll now get an error message if you have invalid states in the pattern.

When I try it it either plays at 49x speed or 51x speed

If the display is too small then there will be a few speeds that can't be selected.

If you really want 50x you could use the script command [[ STEP 50 ]] in the pattern.

Code: Select all

#C [[ STEP 50 ]]
x = 0, y = 0, rule = B/S012345678

This is a big problem for weighted HROT rules.

There's seems a bug here:

Code: Select all

x = 0, y = 0, rule = R2,C2,S2-3,B3,136,NW8888881118810188111888888
5o$5o$2ob2o$5o$5o!

There're 136 neighbors in the weighted neighborhood, but LifeViewer says the maximum neighbors a cell can have is 8.
