lifeviewer bug

[rowett]

On large p2 patterns (like, say, unsynthesizable oscillator 1) and speed slider set to 1x, frames are randomly dropped and the pattern appears to oscillate erratically. Are you using setTimeout for the drawing loop? Maybe requestAnimationFrame would work better.

LifeViewer uses requestAnimationFrame.

I don't see a frame drop on my machine. Switch on Settings->Advanced->Frame Times when viewing the pattern at speed 1x and see if it's a CPU issue.

For the unsynthesizable oscillator the frame times bar is hovering around 40fps and bouncing up and down quite erratically. When I dragged the angle slider to 20 degrees, the frame times bar jumped up to 100%, 30fps, and stayed there, and the frame drop problem stopped. Super weird!

What device are you using?

What device are you using?

here's chrome://version:

Chromium 104.0.5112.105 (Official Build) Built on Raspbian , running on Raspbian 11 (32-bit)

also tested it in Firefox 102.6.0esr (32-bit) also on Raspberry Pi, and frame times bar shows 100%, 3fps. yikes

it may be a chrome://flags issue, I have several turned on, let me know if there are any flags you know of that would interfere with LifeViewer.

Sorry for the double post, but build 813 still has the frame drop bug on my machine.

The p4 and p8 parts appear to run continuously, but the p2 parts are erratic.

Sorry for the double post, but build 813 still has the frame drop bug on my machine.

From the timing data you sent it's not a bug. Your device is just not fast enough to run that pattern at 60fps.

It's a different issue. Rainbow mode was not being restored on hard reset (reset at T=0) if specified in script commands. This is now fixed.

At generations that are a multiple of 64 all alive cells are white when I expect some to be cyan:

Also, pressing reset makes all alive cells white rather than their original cyan. Pressing reset followed by step forward followed by step backward makes all alive cells cyan.

These issues should be fixed now. Thanks for reporting!

When I open the first viewer again (after opening second one), there are timing details displayed (this is unexpected). I have to go to settings and disable them (Advanced/Timing Details, Advanced/Frame Times), otherwise they seem to appear in all viewers on the page, even those without script commands.

Yes this is by design. If people would prefer it not to persist across Viewers on the page I can change it. What is the consensus?

My two cents on this is that there could be a setting for "default for this browser" (saved using localStorage or a cookie or such) and SHOWTIMING/HIDETIMING commands override it.

Run this example pattern for some time, then start pressing "step back". Whatever your running will try to clean up it's trail by moving every 2 steps

yeah. i've been having the same happen to me for a while now, and it's really annoying. (no offense.)

Freshly downloaded portable librewolf shows vertical stripes on buttons.

Works fine in Chrome.
Haven't checked drivers or anything yet, but maybe someone can quickly confirm on his machine.

Librewolf is attempting to block fingerprinting by disabling access to image data. This is screwing up the icons.

See this article for details and for how to disable the feature.

It appears that LifeViewer is now processing historical states at a rate of 64x, but not the pattern's actual evolution.

I can't reproduce this. Perhaps it was fixed in a recent build.

Looks like it was fixed in a silent reupload of build 859, since the bug happened ten minutes ago.

i think there's some confusion with the original Blues theme that applies when no theme is applied: in the conwaylife.com home page, apparently there's an alive ramp of white color? here's an example of a honey farm turning white:

Thanks for reporting! I've reported it to the owner of the home page for a fix.
