[NeoLemmix] Which levels can be beaten using only the new skills?

[namida]

As I'm sure most of you know, the V1.15n update of NeoLemmix added a few new skill types. As of V1.15n-B, you can also force a level to use a specific skillset. So, here's the challenge for each level:

1) Can the level be beaten with only the new skills? (the code to enter on ForceSkillset option is AD51 (V1.17n or newer) or AD50 (V1.16n-B or earlier))
2) If so, assuming an X-of-everything skillset, what is the lowest X the level can be beaten with?
3) Finally, under such conditions, what is the highest % that can be saved?

Just to be clear - that's the order of priority. Highest priority is just beating the level full stop. If that's doable, next priority is to find the smallest X for which it's doable with an X-of-each-new-skill skillset. Once that's been found, the highest % obtainable with said X-of-each skillset is the last task.


<em>Just for reference, on how to set this up:

1) Download <a href="index4265.html?topic=911.0" class="bbc_link" target="_blank">NeoLemmix</a>. Use the latest version if possible; at any rate you definitely need at least V1.15n-B or higher for this topic; but V1.17n+ is recommended due to an additional skill being added in V1.17n.
2) Run the player in question at least once.
3) In the INI file, set ChallengeMode to 1 and ForceSkillset to AD51 (or AD50 if you're using a version older than V1.17n)

You'll notice you start the level with 0 of each skill. This is normal; that's how Challenge Mode works - instead of your skills being limited, you have unlimited skills and it counts how many you use. The reason you need to use Challenge Mode is because obviously, the already-existing levels have 0 of each of the new skills.</em>

<em>Note: Do not use V1.15n-B for the packs where the levels were not yet properly NeoLemmix-converted in that version. In other words, you must use V1.16n or higher for Oh No! More Lemmings!, Holiday Lemmings 94, the Extra Levels, and Lemmings Plus II.</em>

<strong>Keep in mind that these skills are still very new, and as such, may have glitches. Cloner and Glider especially may be vunerable to glitches.</strong>

[namida]

I've done most of Fun to start it off. There's a few more which should be possible but I couldn't be bothered trying - namely Fun 14, 15, 16, 19 and 28.

The lack of destructive skills is the biggest handicap. Builders are also a bit of a loss, though you can somewhat simulate them by using Stacker > Walker > repeat (sometimes with a Platformer before the next Stacker).

The result for Fun 30 was a pretty cool one.

[Minim]

Hey, this is a great idea for a challenge thread and would love to help out. However as there is no link to help me out as a challenger, I have no idea how to create these challenges. So where do I "enter AD50 on the forced skillset to get the 7 new skills only"? On the editor, or on the ini file? Should I update my NeoLemmix? BTW I don't have the original lvl files on my laptop either. Can you please help me?

Edit: OK I've got it now. I've figured out that you must download V1.15-B, and turn on Challenge Mode and CheatCodes for this challenge to work. Please mention that in the OP.

[namida]

You don't have to turn on cheat codes, but I'll mention the rest.

EDIT: Added the other We All Fall Downs, as the same solution works on all four.

[namida]

Here's a few more. The ones in bold are the ones I actually have a confirmed result for, others are just observations.

Tricky 1 - Should be possible using the Stacker-Walker-Platformer combo to substitute builders to get over the lump.
Tricky 2 - Same solution as Fun 13 works here.
Tricky 3 - Very easy 100% with 5 of each.
Tricky 4 - Very easy 100% with 8 of each. Not sure if less might be possible by good use of Stoners.
Tricky 6 - There's an obvious way to get 100% with 5 of each. But there's a not-so-obvious way to get 80% with 4 of each. Replay attached.
Tricky 7 - Fairly easy 96% with 7 of each. Use the mid-air stoner trick for the fall at the end.
Tricky 8 - Obviously possible, but probably requires a pretty large amount of skills.
Tricky 9 - Fairly easy 97% with 3 of each, again using mid-air stoners.
Tricky 10 - Again, should be quite easily possible, but will require a fairly large number of skills.
Tricky 12 - Very easy 96% with 2 of each.
Tricky 13 - Fairly easy 94% with 3 of each.
Tricky 14 - I have no doubt that it's possible, but it'll take a lot of skills. Minimum amount probably won't be a 100%, since I can see stoners being useful here in a similar way to Tricky 6.
Tricky 18 - Very easy 90% with 1 of each, same solution as on Fun 2.
Tricky 19 - Very easy 100% with 1 of each with the same solution as Fun 7.
Tricky 20 - Again, should be possible. Won't be a 100%, as you're going to want a stoner for surviving the drop off the one-way wall.
Tricky 22 - Easy 99% with 1 of each, same solution as Fun 8.
Tricky 29 - Easy 99% with 4 of each. In fact, 100% should be possible, but I've only confirmed 99%.

[namida]

Alright, here's a pretty challenging one!

Taxing 2, 97%, maximum 5 of each skill. (I think with 6 of each, you could do 100%, but minimizing the skill count takes priority over saving the highest possible % here, as long as you're at least reaching the requirement.) I do have a replay, but I might not post it just yet...
Remember that NeoLemmix uses the Amiga version levels, which means there's 100 lemmings in this level, so you're allowed to lose 3 for this.


Aside from that:

Taxing 1 - Should be possible.
Taxing 3 - Should be possible if the time limit doesn't say otherwise.
Taxing 7 - A similar solution to Tricky 4 should work if the time limit doesn't prevent it, but haven't tried yet.
Taxing 9 - Very easily 100%ed with 1 of each.
Taxing 10 - Very easily 100%ed with 5 of each, not sure if 4 of each is possible. Can't re-use the Tricky 6 solution as that only saved 80%.
Taxing 11 - Something similar to Tricky 7 should work, but more skills required due to the need for 100%. Probably need to direct drop to the exit, as you can't use stoners this time.
Taxing 14 - Definitely possible. Good luck finding anyone who can be bothered actually doing it.
Taxing 15 - This one too.
Taxing 16 - Very easy 99% with 3 of each.
Taxing 18 - Almost certain that Fun 11's solution should work here too, but I haven't tried it.
Taxing 19 - 98% with 1 of each. Which should work on Fun 18 too, actually.
Taxing 21 - 100% with 5 of each fairly easily. I can't find any way to do 4 - if the level allowed losing one lemming, it could be done, but it doesn't. (This did give me a nice idea for a trick to use in a custom level, though.)
Taxing 24 - So damn easy. 99% with 1 of each.
Taxing 25 - Fairly sure this should be possible, but not going to try and pull it off.
Taxing 27 - Also definitely possible.
Taxing 28 - 98% with 3 of each. There's several ways to do this, but both 2 skills, and 99% with 3 skills, seem impossible.
Taxing 29 - I'd be VERY surprised if the 100% solution from Tricky 3 doesn't work here.
Taxing 30 - 100% with 1 of each is confirmed possible for all 4 WAFDs.

What does the Mechanic skill do?

[namida]

What does the Mechanic skill do?

Deactivates traps. A single mechanic can deactivate as many traps as he encounters; but it does take him about 2.5 seconds to deactivate a trap (during which time the trap cannot kill other lemmings); he also cannot deactivate a trap if it's in the middle of killing a lemming when he reaches it. Once a mechanic deactivates a trap, that trap is permanently out of order.

There's a tutorial level pack included with NeoCustLemmix; it has one dedicated level for each skill which generally shows their main function, plus one puzzle level that also introduces a few new ideas, either because they just so happen to occur during the level (eg: gliders turning around at walls), or because you're pushed to try them because there seems to be no way without it (eg: swimmers changing directly to climbers) as well as being a, not overly challenging level but a decent puzzle.

[Proxima]

I haven't looked at the game yet, but is there any reason why Fun 27 / Taxing 22 can't be done with just one mid-air stoner?

[namida]

Mayhem 1 - No doubt that it's possible, but that bit at the end is going to take a LOT of skills to get up.
Mayhem 3 - Would be doable with 4 if it weren't for the time limit, possibly less if it weren't 100%. But seems impossible as-is.
Mayhem 6 - 100% requirement makes it a bit hard to minimize skills, the Tricky 9 route doesn't work due to that. I can do it with 7.
Mayhem 7 - Shouldn't be any reason the Fun 20 approach wouldn't work.
Mayhem 8 - Almost certianly possible, but it's another case of having to use the Stacker>Walker alternation to get really high.
Mayhem 10 - 98% with 7 of each. Might seem like you need 8 Platformers, but you can use a few placed-nearly-at-edge stackers for the last little bit, and still stay under 7 of both them and walkers.
Mayhem 11 - The usual 100% 1-of-each WAFD solution still works.
Mayhem 13 - Okay, I didn't actually do this one, but without the skillset being a factor, this level is completely identical to Fun 26, so I can say confidently enough to add it to the list: 100% with 4 of everything.
Mayhem 14 - 97% with 10 of each, might be improvable to 9 with well-placed stoners (and, if we're stuck with 10, then 98% with some better timing).
Mayhem 16 - 100% with 6 of each, quite simple.
Mayhem 17 - Very easy 100% with 6 of each.
Mayhem 18 - Definitely possible. Minimum set probably doesn't give 100%, as I see a lot of potential for stoners here.
Mayhem 21 - 100% with 9 of each. Probably not improvable due to the 100% requirement.
Mayhem 24 - NOT possible. The one pixel thing they start in is only escapable in Fun 30 because you can use a stoner there; the 100% requirement prevents that approach here.
Mayhem 25 - I would think Tricky 13's approach should work here.
Mayhem 27 - 100% with 6 of each. Exactly the same approach as Mayhem 16.
Mayhem 29 - 100% with 5 of each. The new skills actually make *this* level easier. O_O
Mayhem 30 - Should be possible.



Re: Fun 27 / Taxing 22, the answer is "no" for fun 27 (I just overlooked it) and "yes" for taxing 22 (100% requirement; NeoLemmix uses the Amiga version levels as a base - it would work if it was based off the DOS levels where the requirement is only 80%).


I'm thinking I might need to expand this challenge to allow (where impossible under normal circumstances) one destructive skill from the old skillset. Either that, or add a new destructive skill in the next NeoLemmix update, though I'm not exactly sure what kind it might be - but as far as formats and so on go, there's room for exactly one more skill to be added.

[Minim]

Again, you're very quick filling in the results. At least I will still be able to have a chance to post some of mine too.
I did some of the longer levels for you. Here's what I came up with for some of these levels (Well, the benchmark at least):

Fun 14: 12
Fun 15: 18, both by air platforming at the start.
Fun 16: 11
Fun 19: 5
Fun 28: 11

Tricky 1: 4

Taxing 2: 5 (96%)
Taxing 14: 14 (98%)
Taxing 15: 10 (98%)

Unfortunately for the first six results, I ignored the percentage and didn't realise that from the OP I had to record that as well.

[namida]

It's no worries. As I said - first priority is minimizing the skills (well, after confirming it's possible at all, but there are very few levels where possible or not can't be determined just by looking). Especially on these kinds of levels, it may be possible to cut them further - for example, one trick I've noticed but only used in Tricky 6 was make a lemming stack after turning around, then after six steps, make him a Stoner. This can be useful both to save Walkers if you're running high on those, or for walls that are slightly over 12 pixels high (the furthest you can get in a single Stacker-Walker combo).

For Taxing 2 though, not only had I done it, but I managed 97%. Nice going on the others though... 5 for Fun 19 sounds quite impressive!


To give one example of using different tricks, here's Fun 15 with no more than 13 of each skill. It can probably be improved to 12, and there's definitely room for improvement on the % saved (for example, I could've saved one extra lemming very easily by making him a glider).

EDIT: And improved both! 12 of each skill max, and 97% saved. I don't think the skill count can be improved, 98% *might* be possible. 99% would definitely require an extra stacker, so 12 won't be possible on Taxing 1 (and that's without taking into account that I don't think there's enough time for this route either). Note a trick I've used here that I'm actually using quite often - rather than interrupting a stacker than containing the crowd, simply letting one lemming slip past while the stack is being built. No doubt said trick will become somewhat of a staple when I get around to making my next level pack.

[Minim]

Some more results, none being too difficult:

Taxing 22: 3 (100%)
Taxing 27: 5 (78%)
Mayhem 1: 17 (96%)
Mayhem 8: 12, 91% so far but the percentage can surely be improved with better crowd control. I think I controlled them in such a tight space because of the high release rate, and ended up with too many lemmings splatting after the second stoner down the wall.
Mayhem 15: 11 (96%)
Mayhem 18: 10 (95%)
Mayhem 30: 25 (96%) using 25 stackers & 24 platformers. 24 may be possible by stoning to complete the gap to the exit on the right side.

And for Fun 28, I saved 97%

[namida]

Nicely done! Added them to the main post.

Note that NeoLemmix V1.16n has now been released, which has some implications for this topic. Specifically:
1) The Glider glitches are fixed, so solutions that were prevented by those may now be possible.
2) OhNo, H94, Extra and LPII conversions are now done, so we can start on them too.

[Minim]

2) OhNo, H94, Extra and LPII conversions are now done, so we can start on them too.

Really? OK then. I've just downloaded the OhNo version so we'll do that next I think.
And straightaway I found something quite amazing while solving with the new skills. I've solved the first level! (Not something you hear every day is it? ) I've done it by nuking down the floor in the middle. So we do have a ground-removing skill after all, despite being an EXTREMELY unreliable one at that. My overall result, 60% with 6 per skill.

As for the rest of the first 10 Tame levels:
2: 2 per skill (100%)
4: 2 per skill (98%)
7: 9 per skill (94%)
8: 1 per skill (96%)
9: 2 per skill (100%)

7 and 8 make good challenges, but on the other hand 7 might be improvable.

[namida]

I must say that using the nuke never crossed my mind. I'll have to see whether there's any levels in Orig where this may make a difference - in particular, it might be interesting to see what happens if the "Surviving Bombers" gimmick is also used. (Put either 4211 or 00000800 in Forced Gimmick - there's no difference between the two, one's just using the old format fixed codes, and the other is using the newer custom gimmick combinations). This still only allows the use of the nuke once per level.

[namida]

So I decided I'll finish off Tame.

Tame 13 - 98% with 2 of each is quite obvious. But not so obvious, 100% with 2 of each. Replay attached.
Tame 14 - 100% with 4 of each, pretty simple.
Tame 15 - 100% with 2 of each, very simple.
Tame 17 - Doesn't seem to be possible; the best nuke solution I can find only saves 22% (level requires 50%).

The other ones are all very clearly impossible.


EDIT: Also, I'll put this up here now. Here's my 97%-with-5-of-each solution for Taxing 2.

How do I load replays in Lemmix Player Neo? Shift+R doesn't work.

[namida]

EDIT: Never Mind, it's L

Shift+R only applies to playtest mode in the Lemmix editor. In all Lemmix players (Neo or not), it's L.

[namida]

Crazy 2 - 100% with 6 of each. Might be improvable to 5.
Crazy 3 - Very simple 96% with 2 of each; I don't think either part is improvable.
Crazy 4 - 100% with 4 of each, moderate difficulty.
Crazy 5 - 100% with 4 of each, very easy.
Crazy 6 - 100% with 14 of each, pretty obvious, the one thing that might not cross your mind immediately is the need to use a glider.
Crazy 7 - Probably possible, but I am NOT going to try. My theory would be the usual tricks to get out of the starting area, then use a well-placed glider to get down and build a safe landing.
Crazy 10 - Should be possible, but I don't particularly care to try that wall on the left.
Crazy 11 - A very easy 50% with 1 of each.
Crazy 13 - 70% with 2 of each, this one is a little bit tricky but not overly hard.
Crazy 14 - Definitely possible.
Crazy 15 - Very easy 98% with 1 of each.
Crazy 18 - Another definitely-possible-but-verybothersome-looking one.

[Minim]

OK, some of the longer levels results

7: 26 (So far, you need 15 stackers to reach the top of the wall, plus 2 for crowd control and release, and finally another 9 to create a safety net from the overhang, though it may be possible with less if I could find a way to get the lemming to glide to that brick wall to the right of the exit)
10: 16 (98%)
14: 3 (92%) A great puzzle here!
18: Absolutely impossible. 3 minutes isn't enough for me to get over the lollipops and then run all the way to the exit.

[namida]

Added them to the main post.

By the way, just released a V1.16n-B update to NeoLemmix. There's no major need to update for this topic; the changes don't really affect the official game players, they're more relevant to level designers than playing existing levels.

[Minim]

Some results for Wild and the first half of Wicked.

Wild 1: 5 (96%)
Wild 2: 13 (97%)
Wild 3: 6 (96%)
Wild 4: 7 (100%)
Wild 6: 4 (100%)
Wild 10: 6 (95%)
Wild 11: 5 (98%)
Wild 16: 11 (100%)
Wild 19: 12 (96%)
Wild 20: 1 (96%)

Wicked 1: 2 (96%)
Wicked 3: 3 (100%)
Wicked 5: 1 (100%)
Wicked 8: 6 (98%)
Wicked 9: 7 (96%)
Wicked 10: 9 (96%)

Replay attached for Wild 4, and also for Wild 1 if anyone wants to request it.

Edit: Done the rest of Wicked.

12: 7 (97%)
13: 14 (98%)
14: 3 (98%)
15: 7 (94%)
16: 1 (83%)
17: 2 (96%)
18: 5 (96%)
19: 4 (90%)
20: 2 (98%)

The trick to get to the end of Wicked 12 is similar to that of Wild 1, gliding on the terrain, turning round and platforming on the opposite edge, but it's a bit more tricky due to the terrain placement. Wicked 17 is also a good challenge, and as for Wicked 18, well... what a relief that we don't have to worry about hidden traps anymore! The Mechanic is just what the doctor ordered!

[Minim]

I'm thinking I might need to expand this challenge to allow (where impossible under normal circumstances) one destructive skill from the old skillset. Either that, or add a new destructive skill in the next NeoLemmix update, though I'm not exactly sure what kind it might be - but as far as formats and so on go, there's room for exactly one more skill to be added.

I didn't see this part of the thread until now, but I do like this idea of having another digging skill from the original skillset while keeping the others. May I find out the code for each of these skills?

[namida]

If you want to find out the code for any specific skillset, just start up the NeoLemmix Editor, and tick the boxes for the skillset you want. The four-digit code displayed down the bottom of that section is the code for the skillset you've selected. (It also similarly provides the 8-digit code for gimmick combinations)

But, for adding a destructive skill to the existing sets:
AF50 - Bombers
AD58 - Bashers
AD54 - Miners
AD52 - Diggers

One other idea I suggested - and maybe we should exhaust this before we resort to adding an extra skill to the set - is using the Surviving Bombers gimmick, which makes the nuke non-fatal (of course, you still have to be very careful where you use it, to avoid creating fatal falls or reaching the bottom of the level. The ForceGimmick code for enabling it is 00000800 (or 4211; either will work). Another reason I'd prefer to avoid adding more skills is that the next update of NeoLemmix is going to add an 8th new skill (and this will be the last one, as there'd need to be some drastic overhauling of a LOT of things in both the level format and the player code to add any more than this), so that skill would fill up the last empty slot on the skillset. This new skill isn't a destructive skill, but it may have some very significant implications for this topic nonetheless.

The new version of NeoLemmix is up, and the Cloner should have some significant effects on this topic! In some cases it'd just increase the possible percent (for example, you can get 100% on Fun 2 now, still within the one of each limit - but then the new issue is, can you get 110%? ), in some of these it might even be a matter of "use as many cloners as you can spare close to the exit to get a few extra %", but others it might let you save a few skills, especially if a level turns out to be heavily reliant on any permanent skills.

I think we should ban the Cloner and just go with the other 7 skills on this thread. I think the idea of going over the 100% mark is just ridiculous, and plus, we should really be thinking of a literally ground-breaking skill, such as a fencer, laser or maybe even a blow-torcher (Like the one in the Worms games).

Apparantly in challenge mode you can click a skill up to 100 times, but it is very tedious (and it's just plain ridiculous too) to be cloning a lemming 100 times to get the best percentage on every possible level. Fortunately this isn't scheduled to happen in this challenge thread.

All that aside, I made results for every Havoc level that doesn't involve the cloner.

Havoc 2: 19 (96%) (Very annoying, although I used the chains on the right to help me on my way up)
Havoc 5: Impossible because 1, of the awkward but tempting terrain layout and 2, it's a 100%er. The ceiling prevents me from taking the top route. Because it's 100% you can't use a stoner. The only way down the two walls is by gliding but when they glide down the second wall they fly off the edge and thus it's impossible to turn these guys round to reach home. Again, there's madness in the method...
Havoc 6: 6 (100%)
Havoc 8: 18 (98%)
Havoc 9 and 12: 3 (100%)
Havoc 10: 1 (19%)
Havoc 16: 2 (90%)
Havoc 17: 3 (98%) (One of my favourites for this challenge, however it's also a favourite to be improved on, as I used 2 walkers and 2 platformers, and had to use another one of the two to stop stacking after releasing the crowd. Clearing away the traps was extremely fun and made the level much less annoying)
Havoc 15 and 19: Impossible because of buried exits.

It's not unprecedented; the PS3 version has something just like the Cloner, except it's an object rather than a skill (and doesn't turn the clone around). But there are (for example) a level that has 20 lemmings and requires saving 21 (it doesn't use percentages on that version).

My reason for not going with a ground-breaking tool is that ultimately, while it woudl be beneficial to this topic, it probably wouldn't be so beneficial in general. The Cloner is a very new concept; much more so that a destructive skill in a slightly different direction. That's what the addition of a skill needs to take into account - what kind of potential it adds to new levels. Indeed, I've already thought of (though not made) a few interesting ideas for levels using this one; whereas so far, aside from the stroke of genius I had with Stone Hot Sacrifice, I haven't really come up with anything overly great for the rest, unless it's in combination with the Cloner - and even SHS, for example, some of the skills don't really add anything to the puzzle except being there for the sake of using them (and maybe teaching a new idea about them) - for example, the water could be removed removing the need for both the Stoner and the Swimmer; a wall could be placed to remove one of the walkers, etc.

Obviously, Challenge Mode does encourage doing that on challenges that don't specifically prohibit it or give higher priority to something else (such as fewest skills used).

One option I could consider adding in the next update - though I'm not sure how exactly this would work together with Challenge Mode - is adding a third option alongside "use percent" or "use lemming count", which would be "use cloner-adjusted percents" - basically, the percent values would be based off the number of lemmings plus the number of cloners, so that saving every lemming with all cloners used would equal 100%. Needless to say this would just be a cosmetic thing - in fact, percentages already are purely cosmetic in NeoLemmix; behind-the-scenes it works off the lemming count (unlike traditional which does indeed work off the percentages directly - for example, if you make a level with 200 lemmings and set the save requirement at 199, you'll still pass if you save 198, because that's still equal to 99% - this is part of what enables the nuke glitch).

Your score for Crazy 14; is there any reason it wouldn't work with a left-facing entrance? I ask this because I'm changing that level's entrance to left-facing in the next update; currently there's an inconsistency between it (right-facing) and the Genesis version remake of it in Extra (left-facing) which I felt needed to be cleared up, and left makes more sense for this level.

I think there is a problem with the left-facing method. I don't know how I can describe it though, but I'm sure the replay can, attached below. When starting off with a stoner, the lemmings can get a couple of pixels higher by moving in the opposite direction if I platform in the direction they come out. Another stoner quickly follows to block off the edge. then I could jump onto the first stoner (Which is roughly six pixels higher) and platform to the opposite direction. I was able to block the other end with my third stoner. This was where I capitalised on the three-per skill method, and was able to reach the exit with three stackers. With the update I think it's going to take four skills, because you may need to block the edges with three separate stoners for this to work. I hope this is understandable.
