Hi,

Update 2017-08-22: Lix 0.7.x is obsolete -- instead, get the most recent Lix version.

---

Lix 0.7.x experimental build.

Download for Windows
Branch exp in lix-unstable

Keep separate from your stable Lix 0.6.x installation! Levels, tileses, physics all differ. Let's look for physics bugs in this experimental build, make levels solvable, and re-cover levels with solving replays.

Proxima, Nepster, Rubix: See my next post for level pack maintainers -- I'll list which levels were affected by tileset changes, which levels need new proofs due to subtle physics changes, ...

Physics

• Nepster's miner mask
  
• Fix #129: Floater doesn't land inside terrain and turns (Bug found by Ramond in summer 2016)
  
• Floater doesn't go flatter than tumbler. If you assign floater to a fast tumbler, after opening the umbrella, the lix can't gain horizontal flight over the tumbler anymore. Change suggested by Proxima in summer 2016, might affect solution to Steve's Endeavor.
  
• Fix #147: Digger checks inner 14 pixels for steel. Any steel there aborts. On either side of that checked area, there is one lo-res pixel where we ignore steel. (Before, the digger stopped when there was lots of steel on the left, or lots of steel on the right, or a tiny bit amount of steel on either side. That was too complicated.)
  
• Builder creates brick further ahead, like in NL. No builder backstep. Can't seal off climber ledges behind yourself anymore by building immediately after ascending.
  
• Builders and platformes double their most recent brick when they run into a blocker. Reason: This prevents holes in bridges and allows the crowd to follow.
  
• Blocker field narrower by 1 lo-res pixel on both the left and right. Blocker field is exact same as in 0.6, this is simplest. Even though it's possible to prevent crowd from following a builder, with most blocker placements, the crowd follows.
  
• Fix #199: Don't spawn lix outside of torus bounds. Immediately wrap coordinate before the first death check.
  

Tilesets

• Added Raymanni's 3 tilesets. Thanks, Raymanni, for these excellent tilesets, released in the public domain along with Lix. I should have included them in Lix over a year ago.
  
• Remade the oriental set entirely: Removed matt/oriental, remade every tile with new looks and possibly different physics, added some extra tiles. Thanks to geoo for submitting awesome bamboo poles and pebbles! This new set is simon/oriental. All included levels point to the correct new tiles, but, due to changed tile shapes, some levels aren't solvable.
  
• Removed simon/earth, simon/brick, simon/steel. Modified Hrududu slightly, the only level that used simon/steel.
  
• Removed geoo/construction/trampoline.T.
  
• Renamed amanda/occult/occult_* => amanda/occult/*. All levels point to the renamed tiles.
  
• The steam in geoo/construction has alpha channel to look good overlapping itself, and its grey is lighter.

This topic deals with the ancient level format for DOS Lemmings. Level files in this format end with .lvl, 10-level-packs end with .dat.

Consider NeoLemmix or Lix: DOS Lemmings's .lvl/.dat format was popular around 2000 to 2010 for custom levels. Since 2014, the most popular engines are NeoLemmix and Lix. We encourage you to create new levels for these games.

Play old Lemmings games: This topic is about custom levels. If you want to play DMA's old Lemmings, Oh no! More Lemmings, Holiday Lemmings, ..., get a Lemmix player, or run the old games in DOSBox. You don't have to set up Lemmix editor.

See also the 2013 list of game engines and editors.

Lemmix + Eric's Lemmix editor

Lemmix is a lemmings clone that comes with a level editor and is probably your best choice for playing custom levels in .lvl and .dat format, like most of those on the level database, as these levels were designed for Lemmix/CustLemm physics and might not work in other clones. Due to the physics it's also a good choice for the challenges from the Challenges Board. Lemmix features saving and loading replays, savestates and a few more convenient features. Setting it up is a bit complicated, and it has no music.

Setup

Get CustLemm which essentially merges the graphics files from Lemmings and ONML. Extract Lemmix and open the file LemmixStyles.ini. Navigate to [style_9], and two lines below you should find "CommonPath=". Enter the path where CustLemm is located there. (Optional: If you have the original game and/or ONML, find [style_0] and [style_1] and put the paths to Lemmings and ONML there respectively. This will allow you to play the original and ONML levels.)

Now run Lemmix, and go to Tools -> Compiler. Select 'Custom Lemmings' and click 'compile all graphics sets for this style'. (Optional: you can do the same for Original Lemmings and ONML.)

Usage

When opening a .lvl file, you'll be prompted to select a viewer style. Select 'Custom Lemmings' there. When opening a .dat file, you'll be presented with a level list. Right-click on that dialog, select 'change viewer style' and select 'Custom Lemmings'.

To play a level, open it and press [F2]. Press [u] to save a replay of your solution. Press [Shift]+[R] to load a replay during play; make sure you are already playing the correct level.

CustLemmix

An alternative to Lemmix + Lemmix Editor (explained above) to play levels from the level database in a Lemmix player. Download CustLemmix, create a new empty folder, put that executable inside the folder. Rename your level pack to LEVELPAK.DAT and put the pack in the CustLemmix folder. Run CustLemmix to play.

More info about CustLemmix. Don't have CustLemmix in a folder with other Lemmings/Lemmix styles. CustLemmix has styles compiled into the executable and should use those styles. It would prefer other styles from its folder if it found any styles there, thus don't have any styles there.

CustLemm, LemEdit

Obsolete since 2007, but historically important. Both of these run in DosBox. CustLemm is a hack of ONML that loads any given LEVELPAK.DAT instead of the ONML-included levels. See the included readme for instructions.

Download CustLemm

You can select levels 1, 3, 5, 7, 9 from the 10-level pack with the arrow keys in the CustLemm main menu. To play even-numbered levels, you have two ways: Either press F2 in the main menu, enter SKIPLEVELS, then press [Numpad-5] during the preceding odd level to skip the odd level. Or press F2 in the main menu and enter one of these codes:

2: IRRTDTSICR
4: RTDTSIVKCX
6: DTSIRVTMCJ
8: SIVVTDTOCP
10: IRRUDTSQCK

Hi,

Lix 0.6.30 has per-level variable for number of players. This doesn't do anything at all. geoo wanted it. Let's revise what that should do. Only display markings in the editor? Prevent level start with wrong number of players? Distribute hatches to teams before examining how many teams play, then remove hatches for nonexistant teams?

Re level format: Mark hatches in the level text file as belonging to a player, or keep round-robin hatch distribution to teams? How to do neutral hatches? Neutral hatches shouldn't be distributed round-robin in the first place.

Hi,

Edit 2017-08: Lix 0.6 has been obsoleted by Lix 0.8.

Hi,

D Lix has usable singleplayer and editor. You can play the community pack and Rubix's levels. I have begun on the networking last year already, but you can't play yet. The ship can sail in a lot of different directions from here.

Networked mode: Push this towards minimum playability. Coordinate some test games on IRC (quakenet #lix).

NepsterLix: High-quality pack, I want to ship NepsterLix with the game, but I've never prompted Nepster directly about it. I'd host the proofs (= replays that guarantee solvability) on my proof collection on github.

ClamLix: Clam hasn't been active for over a year. ClamLix (level pack) is still awesome. Some levels rely on C++ Lix features (time limit, trampolines, physics details). Should we ship this with the game? We can alter levels slightly, then go for 100 % replay coverage as a community project, like we did last year with the lemforum community pack.

Tilesets: Improve the paper-cut-out look on some Matt tilesets, replace my 10-year-old programmer MS-Paint art with nicely textured and shaded graphics, etc. Lots of little things. Draw idling animations on traps. Jamie does idling animations by overlapping a no-effect gadget with a trap, idling animations are super important.

Music: Icho frequently pushes for this, so worry about this more. Ship a ton of oggs with the game? Ship tracked music, but Ramond and Rubix don't use trackers?

What are the most interesting middle-term goals? What can wait? What other high-level goals are there? Report bugs on github.

LastVersion=10012013000, run in wine.

NL saves config to NeoLemmix147Settings.ini, which I shall call "the file".

I set SoundVolume=24 in the file, play a level and exit the game, then the file says SoundVolume=52.

I set SoundVolume=100 in the file, played a level, sound was louder than last time, exited the game, and again SoundVolume=52 is written in the file.

Hi,

Icho is going to visit me on Friday, 2016-11-11. We will have a surprise video stream for you, starting at 19:00 UTC (= 20:00 German time).

We don't know what we will do on stream. Ideas:

• Play Nepsterlix. I haven't solved the harder levels.
  
• General level critique, à la angry grandpas from the Muppet show.
  
• Icho plays Jazz Jackrabbit. ("never played it before + I am baaaad at jump and runs :P")
  
• Simon plays Command & Conquer, Icho's favorite game from childhood. ("I will rage because I will de-seslect units instead of moving them")

Link: Watch Simon's stream on twitch

Bonus: Right now (Thursday, 19:30 UTC = 20:30 German time), I will stream Jazz Jackrabbit speedruns. Maybe someone of you guys will pop into twitch chat or #lix.

-- Simon

I caught interest in Jazz Jackrabbit 1 speedrunning.

This is lots of memorization and dexterity. The speed is so high, you must memorize enemy locations to react in time during jumps.



Damage boosting in JJ1 feels like flying. When you hit an enemy, it knocks you back into the direction you came from. If you have held the wrong direction long enough before the hit, you bounce off enemies into the direction you want to go, almost at full speed, invincible.

When I made this topic, my times were around 35 minutes, and the world record was 30:32.

Update 2016-11-17: World record get! And continuing to improve.
Update 2018-01-13: I broke the 28-minute barrier with 27:57. We believe 27:00 is humanly impossible.
