lifeviewer bug

[rowett]

Please update that. Also Why lazyslug.com is still using 1276?

It's not. You need to hard refresh you browser to see the latest version.

[R2INT]

Suggestion:
Since we have multiple R2INT rules, why not make 2 slides to control speed, one step(default 1), one speed(default 60)? So that adjusting speed slide to a number below 60 won't display the middle generation. Add a command [[ R2INT ]] if you want, what it does is: Set the base step to 2, and identifying works slightly different.

Here's my take on this:

Instead of using obscure-looking script commands such as [[ R2INT ]], we could instead use more intuitive script commands like [[ STEPINCREMENT 1..8 ]], for example. [[ STEPINCREMENT 2 ]] would function the same as [[ R2INT ]] would in this context. This also adds more flexibility (if, for example, one decides to make a Range-3 INT rule with an emulator ruletable).

Also, instead of being forced to use [[ NOTHROTTLE ]] for guaranteeing even step sizes, instead, a better option would be to throttle only at even generations (or any generation divisible by the STEPINCREMENT value).

What? Going back to generation 0 also reverts the pattern? Let this recording explain the bug:
here

[R2INT]

A similar (or maybe the same) bug occurs in this pattern:

Failed replicator factory:

Code: Select all

x = 284, y = 279, rule = SoManyShipsR2INT
200.6A7$211.A$211.A$211.A$211.A$211.A$211.A55$283.A$283.A$283.A$283.A

78.A7$67.6A!

Probable gun puffer?

An example trigger of this bug occurs when you Select All, Randomize, optionally play it for a little while and then press R (or any reset button) to reset the pattern. It will revert the pattern back to its former state before it was edited.

EDIT: All patterns from build 1282 experience the same bug:

Code: Select all

x = 7, y = 3, rule = B3/S23

Build 1281 appears to have completely broken playback. Experienced both on IOS 18 safari and chromeos 131 chrome.

Edit: For whatever reason, this does NOT affect LV pro???

[CARuler]

the lifeveiwer on the forums will not play for me

[hotdogPi]

MacOS 15.3.2, Safari 18.3.1, haven't paid for Pro, no issues with LifeViewer (checked forums, wiki, and Catagolue).

[confocaloid]

When in doubt, <s>check Lifeline</s> do hard refresh of your browser. Often there's cached old version of LifeViewer. It may be necessary to wait a few hours until the update is available.

The most likely issue that you are experiencing is that Build 1281 is the version you currently have cached on your browser. To access the build number, click on the Help button at the top right. If it is Build 1281, you can hard refresh your browser by pressing Ctrl+F5.

[wirehead]

^^ That might (or might not, up to developers to decide) make sense to do both in LifeViewer and in Golly. Allow adjusting the base step and the delay independently from each other. So it would be possible to have base step 17 with delay 2 seconds, or to have base step 1 with delay 1/8 seconds, and so on.

Interestingly enough old versions of LV did exactly that -- I can confirm build 307 (which is still live on the Marc Niemec Lifepage archive) has two sliders, one for step and one for speed.

Fixed in build 1283. Thanks for the report!

A note on LifeViewer versions:

• Your browser will cache LifeViewer. This means you might not always be using the latest version.
• You can see which version you have by pressing the Help button:
  • "LifeViewer Standard build 1283"
• If you clear the browser's cache and refresh the page it will sometimes get the latest version.
  • On Chrome you can do this with Ctrl-F5.
  • This will work on the LifeViewer Home Page.
• If the website is hosted on a Content Delivery Network (like the forums here) this browser refresh won't always work.
  • The CDN will cache contents for up to 4 hours after which you'll get the latest.

[confocaloid]

In build 1284, when opening a viewer, the playback speed defaults to 1/s instead of 1x. I assume this is a unintentional consequence of a recent change, I initially thought that playback doesn't work at all.

[R2INT]

Here is a bug from 1284:

• Select and randomize a pattern.
• Run the pattern without deselecting.
• Revert the pattern. The random pattern will no longer be selected.
• Pressing Ctrl+Z not only 'reselects' the random pattern, but it also undoes the randomization.

Code: Select all

x = 7, y = 3, rule = B3/S23

Here is a bug from 1284

Fixed in build 1285. Thanks for reporting!

Check that Settings>Playback>Use Saved is not selected. Or set the speed to 1x and click Settings>Playback>Save Speed.

I have to give this bug a dedicated name.
What build when this bug is introduced? I forgot, but I know that bug should be exist since October 2023 or earlier.

This applies to every pop-up viewers, and some embedded viewers such as those in LifeWiki or Catagolue. The only known place unaffected by this bug is the conwaylife.com main page and lazyslug.com.

Try build 1298.

[confocaloid]

At some point recently, LifeViewer selections began working in an unexpected way.

For the following pattern, I expect "Select all" to select a 30-by-30 region (all nonzero cells), the same how it does in Golly, and I believe how LifeViewer did before.

Code: Select all

x = 30, y = 30, rule = LifeHistory
.B$3B$4B$.4B$2.4B$3.4B$4.4B$5.4B$6.4B$7.4B$8.4B$9.4B$10.4B$11.4B$12.
4B$13.4B5.B$14.4B3.BAB$15.4B2.ABA$16.5BABAB$17.5BA2B$18.9B$16.10B2AB$
16.9BA2BAB$16.10B2AB$14.3B.9B$14.3B3.2BA2B$20.BABAB$21.ABA$21.BAB$22.
B!

Instead it now selects a small 8-by-13 region.

In general, "Select all" should select all nonzero cells, regardless of their meanings/interpretations.

The bug still persist.

Another bug, also possible only on touchscreen devices:
1. Use two fingers to zoom, and drag both fingers away from the screen. When a finger goes out of the screen, the camera instantly teleports to a faraway location.

[PiSpaceships]

Sometimes LifeViewer blocks so nothing can be did except zooming. It often occurs on my ebook reader but it once occured in Opera on my phone.

In order to fix any bug I need a repeatable set of steps that reproduces the problem, along with details of the device and browser. Without this information it's unlikely to get fixed.

It just happens randomly. I don't know how to reproduce the bug (it also happens to me).

[pifricted]

Sometimes I can't draw in the last state until I pick it.

Edit:Lifeviewer just reset the gen and do nothing when I click "show' button.
