Mostly style nits, but also:
- Renamed some stuff in anticipation of removing GameEnded.
- Actor decisions are independent, so there's no need to do most of them
in the first part of a tic and the player in the second part; they can
all happen together in the second part.
- waiting_for_input was merged into turn_based, which I think makes it
easier to follow what's going on between tics. Although I just
realized it introduces a bug, so, better fix that next.
- The canvas didn't need to know if we were waiting or not if we just
force the tic offset to 1 while waiting. This also fixed some slight
jitter with force floors.
- CCLP1 #81 requires pushing blocks off of blue walls, which is
impossible in CC2 but allowed in TW Lynx (unclear if this is a lynx
behavior or a tw bug)
- CCLP1 #89 has a tank start on a recessed wall and drive off of it,
expecting the recessed wall to be left alone, but under CC2 rules it
becomes a wall; such walls are now automatically converted to a new
tile, the "doubly recessed wall", which restores the expected behavior
without changing how recessed walls work in general
- CCLP4 #135 expects pressing a blue button to not affect blue tanks
that are currently in mid-slide
In addition, the behavior of blue buttons now matches the Lynx/Steam
behavior: the press is stored as a flag and queued until the tank is
next able to move.
- Teleporters now connect on the fly, rather than having fixed
connections (important because dynamite can destroy teleporters!)
- If custom connections are present, red and brown buttons ONLY use
those, rather than falling back to CC2 connection rules
- Multiple brown buttons connected to the same trap should now work
correctly
Seems to work mechanically though I haven't extensively stress tested it yet. Force floors work the way you'd want them to though (you're given control whenever you can make an input and not otherwise).
There are some graphical bugs with rewinding, but there were some without turn based mode anyway...
