*Thread updated with new information displayed by asterisk.

Welcome to the Challenges board. To avoid confusion, here is an introduction as well as some reminders as to how they work, and how you can take part.

Each challenge thread is traditionally based on the whole set of levels from one game and finding out what are the best records - or if that doesn't apply, which levels can be solved - under one specific criterion. One example is the Maximum Lemmings Saved Records thread, where the record for the most lemmings saved on each level is kept on the opening post. Of course, there are some challenges that only relate to one individual level. For this, we have the Oh No! More Challenges thread.

The results for each challenge are used by a certain engine. Each engine has different physics which can affect the solution for the same level. The engine must be displayed before the thread's title, written in square brackets. If a topic doesn't have an engine / version tag, you should assume it relates to the DOS version.

The format needs to be used like this:

[NeoLemmix] My NeoLemmix Challenge
The link to these engines can be found here. For DOS challenges, DOSBox and LemmixPlayer are acceptable engines. NeoLemmix is not allowed. To clarify, the version of LemmixPlayer allowed is the older versions with seperate EXEs for each pack (downloads archived on the NeoLemmix website); there is a newer all-in-one version that has not yet been verified as accurate-to-DOS (and was known, at least at one point, to have some intentional inaccuracies by the developer).

Incomplete Challenges
Any challenges that are incomplete will be displayed in paraphrases (circular brackets) at the end of the thread if needed. The incomplete tag should only be applied to the main set of levels of each Lemmings game only. Games such as Oh No! More Lemmings and Xmas Lemmings are regarded as expansion packs rather than a main set; whereas Lemmings 2 and 3 are regarded as main groups of levels because they play completely different to each other.

Replays
For solutions to more complicated challenges, a replay is recommended. *To ensure that they are the best quality, it is encouraged that all replays (including screenshots) should be captured from a PC and not from external sources, such as a video recorder or camera. Blurred content would make it unnecessarily harder for readers to understand one's uploaded content.

LemmixPlayer's replay files use the .lrb file extension. The controls are:
L = Load replay
U = Save replay
R = Restart level

NeoLemmix is able to save your level automatically (Unless you've turned this off) when the level is passed. The "Load Replay" icon appears on the far bottom right corner of the full-size skill panel. If you can't find it, Go to the Main Menu, press F3 and click on the "Interface" tab. Uncheck the "Compact Skill Panel" checkbox and the icon should be there the next time you play a level. Modern versions of NeoLemmix use the .nxrp file extension.

For games involving the DOSBox (2, 3, and 3D), you can use a video recorder - There's a useful document here on how to use it - but if you don't know how then using screenshots is fine, as long as you include text as well as precise cursor locations and lemming placements. A .png file is preferred for uploading screenshots.

For Lemmings Revolution, unfortunately I haven't found any information on how to save replays there. You'll probably have to record a video or make some screenshots with descriptions.

Uploading the replay is easy. Clicking the "Attachments and other options" button followed by "browse" should open up a window for you to find the replay you want to upload.

So there you go. Hope everything is clear. Have fun playing the Challenges board!

Just noticed this minor bug whilst looking up all the hotkeys. The F9 button still works though, but still, I couldn't find it on any of the drop-down menus.

Continuing with the subject, may I also suggest that there's a way to display whether the Grid toggle is turned on or off? I'm thinking somewhere at the corner of the screen similar to the co-ordinates of terrain pieces and objects.

So namida just posted a bug involving pickup skills that triggers an error message. I'm getting a similar sort of thing here which according to the level doesn't have any pickup skills at all, but instead had several updrafts, and pre-assigned gliders.

Basically, the error message pops up when loading this level in the editor, but is still playable in the player. It can be found the "War" rank of the "Lemmings United".

Got the new NeoLemmix to launch for the first time. and unsurprisingly, I found another bug.

In the Configure Hotkeys menu, there is no option to select the Shimmier skill with the keyboard, unlike all the other skills. Shouldn't be too hard to fix though, but I thought I'd mention this.

Although not many people would probably want to use the smaller zoom settings anyway, hopefully this bug would provoke a decision whether the lower zooms should be kept or not.

On the interface, when changing from full screen to windowed mode, turning the Compact Skill Panel button off and simultaneously changing the zoom to 1x or 2x, OR if you've started up Neolemmix with these settings, the enhanced skill panel completely disappears, presumably because the window is too small to contain them. The problem also occurs with the Compact Skill Panel on 1x zoom. Fortunately the smaller Skill Panel does appear on the 2x zoom windowed interface.

Here are some of the interfaces I've been given below. May I also mention that on windowed mode, the window's size doesn't change when changing zooms, unless you exit the game and start it up again.

Hi. Looks like I found the first bug of 2019.

I was creating a new level. I was intending to press the scroll-up button. I misclicked and pressed the close button and boom! The editor's gone with my progress gone, with no warning message either.

So what I'm saying is: The pop-up message needs to appear every time I press the close button on the editor, including when I'm making a new level. ATM it only comes up after the level is saved into a file. I hope this makes sense. Thanks.

Hello everyone, and welcome to the first LSC: Level Solving Contest.

As the majority of voters have picked NeoLemmix over Lix as their choice of engine I have gone ahead and created a custom built NeoLemmix level for you to play with.

I've carefully researched everyone's opinions and arguments on which criteria should be prioritised first in terms of competition and this is the order of priority I've come up with for this level.

1. Total Lemmings saved
2. Skills saved
3. Time taken

So here are the rules: The players will play individually for this contest. You must simply solve the level, and then upload a replay of your submission with your name contained in the filename to my Personal Messages box (not on this thread) by 14:00 UTC on December 27, 2018, in other words, you have just over a week. This I hope should allow enough time for anyone who may be taking time off for Christmas but still wish to take part. You can submit more than one replay if you think you've made an improvement, but only one of your replays will be selected as the final result. An example leaderboard will be displayed and ordered like this:

1. Jamie: 50 Lems, 45 SS, 1:04.22 TT 
2. Rick: 50 Lems, 45 SS, 1:06.59 TT
3. Carl: 50 Lems, 43 SS, 1:02.73 TT
4. Grace: 48 Lems, 46 SS, 1:03.86 TT

Key
Lems: Lemmings Saved
SS: Skills left over
TT: Time taken

The winner is the player who saves the most lemmings. The tiebreakers will be Skills left over, followed by the fastest time to rescue the 61st lemming. The Skills left over will be added up at the end of the replay, not by the time you save the requirement.

The winner will get to choose the next level for a competition, as well as select their own criteria and choice for prizes. Obviously I can't be the winner because I'm the host, but thanks to Simon's advice I'll enter the contest anyway just for fun. If he/she decides to upload their own level then they are exempt from winning the next contest, but can still enter if they want to.

Now here's a basic description of the level posted in the attachment below: It has four entrances. Each entrance is placed in separate corners and has a group of lemmings with different athletic abilities, with the exception of those in the top-right corner. With 80 Lemmings and 100 skills provided, you must rescue all four entrances for your result to count. I wish you the best of luck and have fun! Oh, and Merry Christmas.
