Version 3.1 update

More physics updates, UI tweaks and - at long last - a Replay Checker!

Here's what's new:

Replay Checker

• When loading a replay, the replay is first checked for pass/fail status (this is lightning fast and invisible). The result is then displayed in the window caption, including the number of lemmings saved (thanks to hrb264 for this suggestion!).

• This feature will form the basis of an in-development Mass Replay Checker, which will be able to check multiple replays in batch. Let's ensure that the single-check feature is stable first!

Replay Format

• The player's name is now stored in the Replay file.

Physics

• When a Builder is turned by a Blocker, the current step is drawn again to ensure that the bridge fully connects. This does not affect replay timing as the step is drawn instantly, but it may affect replays which used the glitch in order to separate a lemming from the crowd.

• Removed support for variable level boundaries: RetroLemmini will ignore these values wherever they are present in a level file, and instead will default to Top = 2, Bottom = 20, Left = 0, Right = -16.

• Builders are prevented from building past (Y = 4).

• The Top Boundary is taken into account when determining Walker -> Hopper transition, meaning that lemmings cannot step above (Y = 2), and will instead turn around.

• Bugfix - Skill assignment to OhNoing Blockers is now disallowed (as per regular OhNoing lemmings).

UI

• When in Debug mode, the Frame value and X/Y position of [the lemming under the cursor] is shown in the panel info in the format "F:n X:n Y:n".

• Bugfix - Window caption is reset when cancelling Replay mode.

Lemming Sprites

• 'Jumper' renamed to 'Hopper'.
• 'Flapper' renamed to 'OhNoer'.
• 'Flipper' renamed to 'Hoister'.

• All left-facing lemming sprites have been restored to their original positions and are instead offset in-code to match the 3.0+ Builder physics. This does not affect the actual in-game position of the lemming, and is a purely aesthetic tweak to ensure smoother animation, and to restore the original sprites (which should NOT have been changed - I don't know what I was thinking!).

Editor

• RL Editor version 1.7 is included with the download. See the Editor's "About" dialog for update info.

A reminder of what's new as of 3.0.

This is the new version of So Many Spikes, also available in the current Save One pack.
Not sure if IchoTolot needs to bother updating the LOTY pack that close to the end of the playing phase.

Love ya Squidgy! I made and finished a full ROM hack out of this editor so big thank you goes to Squidgy.

It's the most marvellous creation i've ever seen!

If you don't like it, you can always build and release your own levels.

The lems are also lighter (77-77-FF)
Better?

Yes, looks good! Happy to playtest it. Thanks!

Light lemmings make more sense to me than dark lemmings. But I haven't tried to guess Proxima's reasons for dark lemmings. I'll let you know if I find counterarguments to light lemmings in the future.

Dark-green gadgets against the black air are still easily visible to me at your (0, 0x44, 0). I have no answer for buried gadgets.

-- Simon

The following Clear Physics Mode shades can now be user-specified:

$LEMMINGS
  NORMAL $FF7777FF
  ATHLETE $FF00FFFF
  NEUTRAL $FFAA00FF
  ZOMBIE $FF777744
  SELECTED $FFFFFF77
$END

$GADGETS
  SHAPE $FF004400
  TRIGGER $FFFF00FF
$END

Note that "SHAPE" in the GADGETS section will only be applied when Color Cycle is off. TRIGGER is automatically darkened when overlapping, and to match the usual checkerboard pattern.

There is no need to specify shades for Zombie-Athletes, Selected-Neutrals, etc. Let's keep it clean and simple.

Here are 3 solutions for your level. One is most likely close to what's intended, one doesn't use Ballooners at all, and another only uses 6 Spearers.

For a level such as this, my advice would be to keep the open skillset, allow multiple possible solutions, and make use of the talisman system to enforce certain solutions (for example, 'No Ballooners' or '6 Spearers Max' talismans!)

The level doesn't really lend itself well to 'intended skillset only' mainly because the Spearer is a very versatile skill, and the Ballooner a relatively unpredictable one. Let the player find their own way to solve it, then.

It's a very good SuperLemmix level! I look forward to your others.

Some other general comments that you may find helpful:

Please name the .sxlv with the title of the level and the position of the level in the pack. Example: 001_BALLOONERS_VS_SPEARERS.sxlv. This isn't necessary, of course, but it's a very useful habit to get into.

Don't worry too much about difficulty at tihs stage. Just make the levels that you want to make, and you can gauge the difficulty later when your pack has been playtested by someone who doesn't know the solutions!

All the best with your pack!

Quote from: Proxima on June 18, 2026, 11:21:37 PMit means you have to mouse over it to tell what type of object it is, and you don't get to have an overview of the level where you can see everything at once.

I see. OK, I'll take a look at what's possible.

Quote from: Proxima on June 18, 2026, 11:21:37 PMEven if you don't want to do that, I stand by my preference for light hatches (and objects generally) and dark lemmings.

It would probably be fairly easy at this point to abstract the values for {fixed gadget colour} and {all lemming colours} to a text file which can then be user-edited.

That might be the best solution here.

Quote from: WillLem on June 18, 2026, 11:00:59 PMThis wouldn't be trivial to implement tbh. What would be the benefit of being able to see the outline in the case of hatches (which have a 1px trigger point)?

Currently, when an object is buried in terrain, then in clear physics mode you can only see the trigger area -- vastly better than nothing, of course, but it means you have to mouse over it to tell what type of object it is, and you don't get to have an overview of the level where you can see everything at once. Wouldn't it be nice to still be able to see object outlines?

Even if you don't want to do that, I stand by my preference for light hatches (and objects generally) and dark lemmings.

Quote from: heart66 on June 17, 2026, 12:40:43 PMWe were both correct, the new skills will show but not the edited title.

Good catch! The Author field also needs to be updated.

Fixed in NLCEPlayer commit 59e2ff8 and SLXPlayer commit fda6bae.
