Everything what Dullstar wrote was actionable, thus constructive. Feel free to ask if it's not clear how to fix the issues. Feel free to disagree that something is an issue.

Steel/earth distinction is perhaps the least actionable; it's not necessarily clear which exact tiles the problem are. In a pinch, you can ask more people to test.

Thanks for the reply! Sorry for my belated reply.

The programming example you gave doesn't feel to me like much of an analogy to the "is something that" in English.

Here, my desired nuance wasn't filler phrases: Certainly, programming languages have few constructs that could be outright omitted with the same meaning. Thus, "is something that" isn't a suitable example here.

I wanted to draw attention to how the payload -- the businees logic in programming, the big ideas in writing -- should not be bloated by bookkeeping. The reader can often figure out the bookkeeping themselves, or the bookkeeping can be written somewhere else.

For such avoidance of bookkeeping, "if you don't know what X is" is a better example than "is something that". The meaning will change when we leave out "if you don't know what X is", but it really doesn't matter; we want to cut to the point immediately. The change in meaning happens to be irrelevant here, even better.

Feel free to apply the Simon culls below to some example writings of mine in this forum, I welcome the closer look and debate.

All right, I'll try once I see a particularly tasty target. I read practically everything by you, doesn't matter which topic on the forums.

Courtesy is interesting. People interpret bloated, deliberately weakened statements as courteous. When an author prunes the writing, people should be happy that the author doesn't waste their time, they shouldn't feel uncomfortable. <_<;;

Sorry for any of my slowness on the forums these days. I'm still stuck in the editor's undo feature for editor tile insertions/removals.



My current design problem appears to require triple dispatch. (If three objects are of specific subclasses each, call a certain method.) This is likely a misdesign in the classes, I merely don't see how. I expected double dispatch to appear, I have parallel class hierarchies that seem like the least-worst solution.

Maybe I'll have to lie on the psychiatric bench that is the Lemmings Forums, and make a detailed topic about this.

I hesitate making intricate programming design topics here though: It's really software development at heart, not of general Lemmings interest, and probably more sensible on Software Engineering stack overflow. It would be a genuine call for help, on a nontrivial and highly specific problem in my personal areas of expertise and interest (Lemmings, OOP) -- thus obvious solutions won't fit.

On the other hand, it's easier to explain the problem on Lemmings Forums, because we have a bunch of developers here that will readily understand the problem. And if we find the least-worst solution, maybe it'll be helpful too for somebody in the future.

Hmm. After this rambling, I should really make this topic.

Edit: Adding/removing tiles is functional, using the visitor pattern for the common double dispatch and dynamic casting to avoid introducing a second visitor on the parallel hierarchy. Topic here will still be reasonable, it still feels awkward.

We'll play today at 16:00 UTC (in 8 hours, 45 minutes). See you!

Session is over. It was a small 4-player session, still very nice. See you all next time!

Welcome to the forums!

Yes, Rubix should attach his 2-player L1-to-Lix conversions here.

-- Simon

Added Turrican to first post, thanks!

-- Simon

I'm happy to play next Sunday, June 14.

I propose 16:00 UTC, the same as last session. Table that converts UTC to other times

-- Simon

There are really two problems here:

• Internal representation while the replay is in RAM. We want to reorder cloners in the replay without the replay failing unrelated assignments. This internal representation I had in mind as target for the idea with the list of integers (= recursive tracking of sources plus the n-th time the source has produced a lemming).
• Serialization to file. We don't necessarily have to touch the format definition; we might work around it and avoid a format change.
  

Maybe we can serialize the IDs to the classical integers (including their odd behavior, and future NL must remember 12.09's quirks of how it assigns IDs internally, to use that quirk for this serialization of list-of-integer to a single integer). When the replay gets loaded, the integer IDs convert to list-of-integer.

The problem is that this loading-and-converting seems to need a physical passthrough, or at least an interpretation of RR changes. Nasty nasty nasty, many little details to squish in mind. There is no clear good and bad here.
