Much more stylistic, you don't need to repeat "game.currentmenuname" for
each case, and you don't need to deal with the dangling first "if" that
doesn't have an "else".
I presume it was meant to have the text of the currently-selected menu
option inside it, before the code switched over to using the indice of
the currently-selected menu instead? Would've been more error-prone to
use the text name directly.
Stringly-typed things are bad, because if you make a typo when typing
out a string, it's not caught at compile-time. And in the case of this
menu system, you'd have to do an excessive amount of testing to uncover
any bugs caused by a typo. Why do that when you can just use an enum and
catch compile-time errors instead?
Also, you can't use switch-case statements on stringly-typed variables.
So every menu name is now in the enum Menu::MenuName, but you can simply
refer to a menu name by just prefixing it with Menu::.
Unfortunately, I've had to change the "continue" menu name to be
"continuemenu", because "continue" is a keyword in C and C++. Also, it
looks like "timetrialcomplete4" is an unused menu name, even though it
was referenced in Render.cpp.
I think it's about time that this number be updated, yeah? This isn't to
say that 2.3 is finished or almost finished or anything, this is just to
clearly differentiate that this isn't 2.2.
If you have invincibility mode or slowdown enabled, the game will not
let you select the Secret Lab, Time Trials, or No Death Mode. To make
this clearer, this commit grays out said options if they are disabled
for that reason.
The game won't let you select the Secret Lab if you're in invincibility
mode, probably so you can't set illegitimate Super Gravitron records
just by standing there and doing nothing.
However, for some reason, it'll still let you select the Secret Lab even
if you've slowed down the game. For consistency, let's prevent selecting
the Secret Lab if the game isn't running at fullspeed, too.
I've converted every "else if"-chain in menu render/input code to be a
case-switch, except for the levels list, the "game options" menu
(because it has the MMMMMM menu option which isn't a compile-time
constant), and the "play" menu (because it has the Secret Lab menu
option which also isn't a compile-time option).
I also did NOT convert some case-switches relating to unlocks in
Input.cpp, mostly because they use a system where the "if we have this
unlocked" conditional is a part of the "if this is the current menu
option" conditional, and they use the 'else' branch to play a sad sound
if that "if we have this unlocked" conditional fails.
I've also converted the game.gameframerate and game.crewrescued() "else
if"-chains to be case-switches instead.
There was one level that was indented with 2 spaces instead of 4, which
made everything else look weird. Then some lines were randomly indented
further for no reason.
Doing this before the next commit is done so as to not make the next
commit noisier.
This removes duplicate code that came about as a result of various
possible permutations of menu options, depending on being M&P, having no
custom level support, having no editor support, and having MMMMMM.
The menus with such permutations are the following:
- main menu
- "start game" is gone in MAKEANDPLAY
- "player levels" is gone in NO_CUSTOM_LEVELS
- "view credits" is gone in MAKEANDPLAY
- "game options"
- "unlock play data" is gone in MAKEANDPLAY
- "soundtrack" is gone if you don't have an mmmmmm.vvv file
- "player levels"
- "level editor" is gone in NO_EDITOR
I achieve this de-duplication by clever use of calculating offsets,
which I feel is the best way to de-duplicate the code with the least
amount of work, if a little brittle.
The other options are to (1) put function pointers on each MenuOption
object, which is pretty verbose and would inflate Game::createmenu() by
a lot, (2) switch all game.currentmenuoption checks to instead check for
the text of the currently-selected menu option, which is very
error-prone because if you make a typo it won't be caught at
compile-time, (3) add a unique ID to each MenuOption object that
represents a text but will error at compile-time if you make a typo,
however this just duplicates all the menu option text, which is more
code than was duplicated previously.
So I just went with this one.
I don't know why you would have to have both defined simultaneously, but
now you can.
The compile fail was caused by the fact that if both were defined, then
there would be an expression like this in Map.cpp:
switch (t)
{
case 0:
}
which is an invalid expression.
The solution is to put 'case 0:' into the MAKEANDPLAY ifdef-guard as
well.
Just like I moved the menu ACTION press handler, I'm doing this as well.
It only removes one level of indentation, but it makes titlerender()
easier to understand.
Just like before, I have to put the separate function first, else
titlerender() won't know what it is.
Previously, the code looked something like:
else { if (...) {...} else { if (...) {...} else { etc. } }
And kept indenting every time there was an else-if.
This commit puts all else-ifs on the same indentation level, so it
doesn't slowly push the code to the right.
This takes out 3 indentation levels from the ACTION press handling,
making titleinput() easier to read as a whole.
Unfortunately, we have to put menuactionpress() first, even though I'd
want it the other way around, otherwise titleinput() won't know what it
is.
If we need it (which I don't think we will be anytime soon) we can
always just get it back through source control. Otherwise, it simply
gets in the way.
Firstly, menu options are no longer ad-hoc objects, and are added by
using Game::option() (this is the biggest change). This removes the
vector Game::menuoptionsactive, and Game::menuoptions is now a vector of
MenuOption instead of std::string.
Secondly, the manual tracker variable of the amount of menu options,
Game::nummenuoptions, has been removed, in favor of using vectors
properly and using Game::menuoptions::size().
As a result, a lot of copy-pasted code has been removed from
Game::createmenu(), mostly due to having to have different versions of
menus depending on whether or not we have certain defines, or having an
mmmmmm.vvv file inside the VVVVVV directory. In the old days, you
couldn't just add or remove a menu option conveniently, you had to
shuffle around the position of every other menu option too, which
resulted in lots of copy-pasted code. But now this copy-pasted code has
been de-duplicated, at least in Game::createmenu().
This removes map.numshinytrinkets in favor of using
map.shinytrinkets.size(). Having automatic length tracking is much less
error-prone and less tedious.
It's treated like a bool anyway, so might as well make it one.
This also necessitates updating every single instance where it or an
element inside it is used, too.
Looks like it was here from that arg passing stuff from earlier, as a
workaround to not pass args around. Well, there's no need to create an
extra UtilityClass now either, just use the one in the global namespace.
