This once again fixes the facing directions of crewmates upon room load,
except now it covers more cases.
So, here is the saga so far:
- 2.0 (presumably) to 2.2: crewmate direction fix is special-cased at
the end of mapclass::loadlevel(). Only covers crewmates created during
the room load, does not cover crewmates created from scripts, only
covers state 18 of crewmates.
- 2.3 currently (after #220): crewmate direction fix is moved to
entityclass::createentity(), which covers every avenue of crewmate
creation (including from scripts), but still only covers state 18.
- This commit: crewmate direction fix now covers every possible state of
the crewmate, also does not copy-paste any code.
What I've done instead is to make it so createentity() will immediately
call updateentities() on the pushed-back entity. This is kludge-y, but
is completely okay to do, because unlike other entities, crewmate
entities never change their state or have any side-effects from
double-evaluation, meaning calling updateentities() on them is
idempotent and it's okay to call their updateentities() more than once.
This does have the slight danger that if the states of crewmates were to
change in the future to no longer be idempotent, this would end up
resulting in a somewhat hard-to-track-down double-evaluation bug, but
it's worth taking that risk.
This fix is not applied to entity 14 (the supercrewmate) because it is
possible that calling updateentities() on it will immediately remove the
entity, which is not idempotent (it's changing the state of something
outside the object). Supercrewmates are a bit difficult to work with
outside of the main game anyways, and if you spawn them you could
probably just use the changedir() script command to fix their direction,
so I'm not inclined to fix this for them anyway.
