The fourth is simply a duplicate of ship_collision for bullets. A
bit redundant, but I figure it's clearer of a definition. Besides,
this opens up the door to possibly making bullets a different struct
type in the future, if that turns out to be desirable.
Starfighter uses an absurdly crude method for wrapping text which
basically fails very frequently when large words are chosen. The only
reason it got away with it is because text strings don't vary. Well,
I've been quite annoyed by having to test for this and rework my
text so much, so I've added in a secondary system: if it's really
close to the edge, and the next three characters are going to be
letters, it adds a hyphen and moves on to the next line. This still
isn't 100% fool-proof, but it should catch most problems.
Also removed the "temp fix" which shifted the letters by a pixel in
code, and just shifted them in the actual image. I don't understand
why the "temp fix" was there in the first place, to be honest.
The idea is clearly supposed to be breaking the boss in two and then
destroying the halves, so it makes no sense for the wings you break
off to also act as shields, which they did. Pretty much all this did
was cause a lot of shots to be wasted.
I don't really understand why this code was implemented only for the
boss and not for anyone else. My only guess is it was designed to make
the level harder by letting enemies fire backwards while you can't,
but mine-droppers can already effectively do that.
The primary reason I decided to make sure they all face forward is I
was finding it to be nearly impossible to get through this level in
Nightmare difficulty; those ships being able to shoot backwards is
a HUGE advantage, because it's almost impossible to position yourself
in an area that's safe.
It may be that the unfair previous behavior was put in to compensate
for the AI's frankly asinine movement pattern. The random movement is
fine most places, but here, it's blatantly obvious that it's random,
and the enemy ships pay a steep price for it. What the ships should
be doing is positioning themselves so that they end up shooting or
dropping mines at the player. But the boss itself also has such a
positioning problem anyway; that should be properly fixed in the
future, so I might as well do the same for the smaller ships when
that time comes.
I honestly don't understand why these cheats were here. Preventing
enemies from moving breaks some missions and doesn't do anything
useful, and preventing enemies from firing is basically no better
than the invincibility cheat (and might even be worse, if it applies
to Sid; I didn't check).
This feature is just annoying if for some reason you want to leave
the game to do something else while you wait for something. That
would normally be a defect, but I can't count the number of times
I've been rushing through to get to a particular area, using cheats,
and had to wait for some mission condition, and this is only made
worse by not being able to do some other work while I wait for it.
This long-standing bug was caused by using blending when trying to
copy an image, though for some reason it was inconsistent. Thanks to
everyone on the SDL mailing list for helping me solve this one!
