NeoLemmix: Other challenges

[Proxima]

This topic collects results for pass/fail challenges, i.e. ones where we ask "Which levels are possible with a given condition?" and don't have a numerical component to the results. These tend to give rise to shorter topics than numerical challenges, simply because there is no room for improving on existing results, so after a discussion on discord we decided to combine them into a single topic. If any of them become popular enough to move on to other packs beyond Redux, we can split them out into separate topics, but for now, we'll combine them and see how it goes.

Links to pass/fail challenges for DOS Lemmings:
Which levels are possible assigning skills to only one lemming?
Which levels are possible with one skill per lemming?
Which levels are possible with one of each (classic 8) skill?
Which levels are possible only assigning skills to lemmings facing in one direction?
Which levels are possible with no lemmings turning around?
Which levels are possible with undamaged terrain?
Which levels are possible with fixed RR 99?

For now, I am excluding the following challenges:
* Which levels are possible to solve in under one minute? -- This is tracked in Fastest Time Records.
* Which levels are possible with one type of skill? -- For NeoLemmix, this is tracked in Fewest different kinds of skill.
* Which levels are possible with destruction only? -- This challenge was proposed but never really got off the ground.
* Which levels are possible with all skills used? -- Same applies to this one.
* Which levels are possible without changing the release rate? -- All levels that were impossible for this challenge were only impossible because of time. Redux has removed the time limit on 90% of levels, so the challenge is no longer interesting. (For the record, "Flow Control" is possible without changing the release rate, both in DOS Lemmings and NeoLemmix.)

And now, on to the results!

Assign skills to only one lemming - Lemmings Redux

Gentle: All except 3, 4, 6, 28, 30, 32
Quirky: All except 2, 3, 10, 13, 15, 20, 21, 24, 28, 29
Zany: 1, 2, 3, 4, 6, 7, 8, 9, 10, 16, 18, 19, 20, 21, 24, 25, 26, 28, 31

Nice idea! We never really followed the pass/fail (Or maybe we could call it fixed) challenges; therefore they're the ones that fall towards the bottom the quickest because it's either yes/no. To collaborate the more interesting ones together is a brainwave indeed in terms of keeping the board tidy. I'll keep an eye on these challenge topics, maybe except for the one I'm about to explain below.

The only dilemma however is the Classic 8 skills challenge. Apart from "It's Hero Time" somebody will need to convert these levels and upload an attachment upon request. Redux is a huge pack and there could be a case of "Repeat Level syndrome". Maybe select some of namida's LP packs as an example? Most of his levels are short and compact and could make good one-per-skill levels. You'll also need to watch out for long/multiple gaps, and bottom-to-top levels, as these are usually regarded as impossible.

1. Download Notepad++ (or any other text editor with a "Replace In Files" function + regular expressions support).
2. Create a copy of the pack you want to make this change to.
3. Modify the info.nxmi to add a "(1 of each)" or whatever note to the title, so you don't get confused about which one is the normal one vs modified one in the Level Select menu.
4. Run the following Replace In Files on the pattern "*.nxlv", making sure to set the correct path, enable the "Include subfolders" option, and enable the "Regular expressions" and ". matches newline" settings:
From: \$SKILLSET.*?\$END
To: \$SKILLSET\nCLIMBER 1\nFLOATER 1\nBOMBER 1\nBLOCKER 1\nBUILDER 1\nBASHER 1\nMINER 1\nDIGGER 1\n\$END

This will change the skillset of all levels in the pack to 1 of each traditional skill.

OK, just downloaded the latest Notepad++ version today, but because this is new to me, I haven't got the hang of it. I was able to run and open up the document, but couldn't find anything to configure the "Include subfolders", "Regular expressions" and ". matches newline" buttons.

Maybe a video tutorial will help me with this? I'll keep trying.

Sure, here you go: https://youtu.be/qYYmd9XQnQQ

The first 12 minutes show you how to do it, while explaining in some depth how it works - which is useful if you want to understand the general idea so you can expand it to other things (like doing your own custom skillsets instead of just copy-pasting a formula that someone else gives).

Alternatively, if you just want a crash course on "where exactly do I enter the settings I was given", start at the 12 minute mark. (Even if you watch the full video, it's probably useful to watch the post-12-min section just as a quick recap of "here's everything that's actually part of the "how to do it" rather than just "why does this work" stuff".)

OK, I saw the video this morning and managed it! I nearly confused the front slash for the back slash as you wrote slash in. Also, a level could've been tested on the NeoLemmix player itself as well as the document, but thanks for the help.

The 1 of each pack has been uploaded for anyone interested.

I've made a tool which makes this even easier: https://www.lemmingsforums.net/index.php?topic=5382.0

I don't see this as necessary. I can already tell in the text editor that the correct change has occurred, and the viewer knows what should happen; why do I need to specifically add to the video to show it? I could understand this if it wasn't clear exactly what I was describing, but I think this is a simple enough case that it's not needed.

Here's the modified version of Lemmings Redux for the 1-of-each challenge, based on today's update to the Redux pack.
