For example, you can now make connections with the connection tool.
Remarkable.
Unfortunately, implicit connections aren't updated as you edit the level
yet.
Also came with some refactors for searching a level and whatnot.
The default is now what I /think/ is the Lynx behavior: try to push the
block first, and only give it a pending direction if the push fails.
CC2 always uses the pending mechanism.
Since sliding happens either on cell arrival or in the actor's idle
phase, the actor will always have a pending slide by the end of a tic,
so this code doesn't actually do anything.
This seems to simplify things and also explain the CC2 semantics: force
floors activate while being stood on (which happens, I guess, during
idle), so it applies to objects that start the level on force floors.
This was probably done to make force floor flipping work, too. On the
other hand, ice still only activates when being stepped on.
This does simplify things a bit, and it also fixes the replay for CC2LP1
level 160, Sneak Around. It breaks three Voting replays, unfortunately,
but doesn't break anything else, so I'm inclined to call it better.
I had it mostly right based on experimentation, but had the conditions
inside-out, which allowed this case to slip through the cracks. This
makes the Settlement of Arrakis replay sync.
Eliminates a number of annoying little hacks by getting rid of
`slide_mode` and instead trusting the terrain, live, like CC2 seems to
do (and Lynx definitely does).
- Players and monsters do, in fact, block each other. The helmet only
prevents death.
- Death happens during collision check, which is the entire reason items
don't save you: you're collided with first! This allows removing
several special cases.
- Spring mining is prevented almost incidentally, by virtue of collision
being checked both at decision time and movement time. It /can/
happen to actors other than the player, but seemingly not blocks.
- Some monsters, whose movement is essentially forced anyway, skip the
decision time collision check. This includes doppelgangers, which is
why they always spring mine.
