This is mainly because the old "limit" functions were all restricted
to certain types, which is incredibly silly given how simple they are.
Macros are much simpler, and a warning gets raised if they're used
improperly with multiple types, anyway.
In the process, I also found and fixed a bug: it seems the original
author intended for escaping enemies to gradually accelerate to
fleeing speed, but the low value was indicated as the max value, and
the way limitFloat was written, that caused the max value to be used
(it was supposed to reduce the speed to a minimum of -15, but it
instead effectively assigned the speed to -15). It might be a good
idea to re-implement the old buggy behavior intentionally; depends
on whether the acceleration of jumping looks better or worse than
just immediately going to jump speed.
Started out adjusting prices, then ended up doing other things
while testing. Committing this now before I start doing other
random stuff!
But all of the changes are related to balancing difficulty, mostly
with prices, except for a couple bugfixes in the shop. Most notably:
* Ammo now costs $10, not $50. You no longer have to worry about
saving ammo quite as much as a result.
* Plasma upgrades' cost is now calculated differently, and the result
is slightly lower prices than before.
* Easy mode now grants the player more max ammo than other difficulties.
* Increasing max plasma ammo now costs less at the start, and increases
in cost faster.
* You increase max plasma ammo by 25 at a time, not 10. (10 was just too
small of a number.)
* Destroying enemy ships no longer gives you money. I found that, even
in hard mode, I had *way* too much money coming in, and this cuts it
down substantially. It also makes the shield bonus at the end of missions
much more significant. To compensate for the loss of massive bonuses
bosses used to give, these bosses now drop a lot more stuff.
* Kline has decreased health in his first encounter, and increased health
in his last two encounters (the numbers have been reversed).
I found it kind of odd to be able to manually save to the autosave
slot, *and* have no reliable way to even know what the autosave
slot is. I noticed that it's an actual problem when my brothers
played Starfighter; one of them used an autosave slot, and the
other unwittingly ended up erasing the first one's save because of
this. To fix this, I have replaced the behavior of allowing the
player to define a slot as autosave, with a dedicated autosave
slot.
While I was there, I had no choice but to vastly improve on this
game's *atrocious* menu system. Granted, I didn't do much more
than replace the magic numbers with enums, but it makes the code
much more clear and more easy to edit.
In most cases, this has also resulted in limits being lifted. (The
only place I haven't done this is for planets in intermission.cpp,
but I think I'll take away that 10-planet limit as well.)
