Previously, in tower mode, being inside walls would just kill you, unlike
being inside walls outside tower mode, which was somewhat confusing.
Also, spikes behaved differently with regards to invincibility, being
unsolid in towers but solid outside them.
This does not change the behaviour of the "edge" spikes in towers.
This fixes a bug where warp lines created through createentity wouldn't
work without there already being a warp line present in the room as an
edentity.
Yikes. Somebody brought this to my attention, I didn't even remember that I'd written it. "Spa" or "Spastic" is kind of a south park esque slang term that used to be pretty common in Ireland, which I used without even thinking about it. It's definitely not something I would say anymore, 10 years on, and it's something I shouldn't have said at the time either. I'm sorry :(
(somebody on twitter was asking me about how much cleaning up of the source code I did before launching this. I think this commit kinda answers that)
* Add entity type attribute checks to getcrewman()
This means that the game is no longer able to target other non-crewmate
entities when it looks for a crewmate.
This has actually happened in practice. A command like
position(cyan,above) could position the text box above a horizontal warp
line instead of the intended crewmate.
This is because getcrewman() previously only checked the rule attributes
of entities, and if their rule happened to be 6 or 7. Usually this
corresponds with crewmates being unflipped or flipped, respectively.
But warp lines' rules overlap with rules 6 and 7. If a warp line is
vertical, its rule is 5, and if it is horizontal, its rule is 7.
Now, usually, this wouldn't be an issue, but getcrewman() does a color
check as well. And for cyan, that is color 0. However, if an entity
doesn't use a color, it just defaults to color 0. So, getcrewman() found
an entity with a rule of 7 and a color of 0. This must mean it's a cyan
crewmate! But, well, it's actually just a horizontal warp line.
This commit prevents the above from happening.
Resizing the vector does the same thing that the loops did, it changes
the size for the vector and initializes it with default-constructed
elements (or 0 or its equivalent for POD types).
Where a specific value is needed, it is set with the second
parameter of resize().
