Also, lifehistory cells are incorrectly affected by layers:

And hexagonal and triangular grids just don't work with it at all:

I've also committed one new alias.

Also, is it intended that pressing the small STOP button at the top middle doesn't turn it off? It definitely turns green when pressed, implying there's some sort of interaction, but I can't get it to turn off.

Layers don't seem to be affected by cellborders.

Cell borders (and the grid lines if enabled) are only drawn on the bottom layer.

[rowett]

Also, lifehistory cells are incorrectly affected by layers

No it's correct. Marked states only appear in the bottom layer.

And hexagonal and triangular grids just don't work with it at all

True, layers are only currently supported on square and offset square grids.

Inconsistencies with history layering

What is the inconsistency?

(also note that in Generations the back layer isn't darker)

This has been fixed for the next released build.

Great, thanks.

The STOP and START buttons are indicators and can't be pressed. If I lock them they go grey so I may introduce another UI state that just prevents them getting highlighted when the mouse is over them.

EDIT: I've made them buttons.

Build 387 is now live on the Forums and LifeWiki

Please note: you will need to refresh your browser to use the new build (Ctrl-F5 on Chrome)

Enhancements since the last released build:

• Generations rules now have brightness shading when using layers
• performance improvement for THEMEs without history
• added another alias
• START indicator now toggles AUTOSTART if defined
  • hotkey Alt+"O" to toggle
  • if START disabled when LOOP defined then playback stops when Loop happens at T=0
• STOP indicator now toggles STOP if defined
  • hotkey Alt+"P" to toggle

Fixes since the last released build:

• toggle LOOP when defined (hotkey Shift "P") wasn't working
• take screenshot (hotkey "O") was not working

The updated hotkey map detailing the LifeViewer keyboard controls is here.

Comments, feedback, suggestions and bug reports welcome!

Still seems a bit odd to me that they display the alive colour though.

Can the sliders be greyed out to indicate this?

Inconsistencies with history layering

What is the inconsistency?

From what I can see, on 2-state rules, the history cells only appear in the very back, whereas with generations they're duplicated across all other layers as with live cells.

Yes this is fixed for the next released build.

Here's some range-1 1D rule aliases from Mirek's site:

W54: Brownian motion
W110: Fishing-net (also Wolfram 110 according to Golly)
W22: Heavy triangles (also Wolfram 22 according to golly)
W90: Linear A
W150: Linear B
W18: Pascal's Triangle
W30: Randomizer 1 (also Wolfram 30 according to Golly)
W45: Randomizer 2

There's also plenty aliases for 1D binary rules with larger ranges, but unfortunately these aren't yet supported.

[muzik]

Can the Change Rule popup be made part of the viewer instead of as an external popup? And can aliases be selected somewhat similarly to in Golly?

Also, is it possible to download a copy of LifeViewer for offline usage (PC)? Currently there's no other program I know of that can simulate HROT (R>2) rules that doesn't require an internet connection.

For offline use you can just save a copy of any Web page containing LifeViewer. It should work fine with no Internet connection. You can try editing the HTML to adjust things like the default canvas size, too -- sometimes it's nice to not be limited by LifeWiki or forum defaults.

There are simple examples here of what minimal HTML for LifeViewer might look like.

It's on the backlog.

Yes you need two files:

• viewer.html
• lv-plugin.js

Right click each one and "Save link as..."

Assuming you put viewer.html in a folder called muzik you then need to create a subfolder muzik/js and put lv-plugin.js there. You can then just open viewer.html in your browser.

If you want the LifeViewer window to be bigger than the default 560x560 edit viewer.html and change the line:

Code: Select all

<canvas width="560" height="560"></canvas>

This (and the offline copy of the viewer) works fantastically!

Randomizer 2 seems to be missing a W in the aliases screen though, so that should probably be fixed. And the 1D aliases in general are not alphabetically sorted.

Random thought: is there/will there be an option to change the colour of help text and the like through scripting?

Fixed, thanks.

Not as script commands. I've been debating adding preferences which would persist across sessions.

Can opening the settings menu be made to lock the gameplay so you can't scroll or draw on the pattern, like what happens with the help menu?

The locking seems to work. can it also darken the pattern slightly like the Help menu does?

[rowett]

Yes

[muzik]

The lifeviewer window can get occluded by the post reply button set the bottom of the page, I'm not sure if that's the fault of the viewer itself though.

Similar stuff happens over at Catagolue.

Build 393 is now live on the Forums and LifeWiki

Please note: you will need to refresh your browser to use the new build (Ctrl-F5 on Chrome)

Enhancements since the last released build:

• added experimental support for 2-state Margolus rules
  • rule format is Mn0,n1,n2,n3,n4,n5,n6,n7,n8,n9,n10,n11,n12,n13,n14,n15
    • where n0 to n15 are integers from 0 to 15
  • also supports MS,Dn0;n1;n2;n3;n4;n5;n6;n7;n8;n9;n10;n11;n12;n13;n14;n15 format
  • bounded grids and alternate rules are allowed
  • rules where n0 = 15 and n15 = 0 are replaced with equivalent rules that don't strobe
  • rules where n0 > 0 are not allowed apart from the case above
• using [[ GRIDMAJOR ]] creates a custom Theme

Exciting new developments I see!

Will higher-range Margolus rules be supported? These (or at least an isotropic outer-totalistic subset thereof) could be allowed simply by letting the range parameter in LtL/HROT be a half-integer. WolframAlpha allows half-integer ranges for 1D rules, and Margolus rules are basically just the 2D equivalents of these.

Also, since this is just an early build: will these ever display like true block cellular automata do?
