Unless it's the main menu, or unless it's not the same menu. Whether or
not the menu is the same is left up to the caller, because some menus
could be the same but use different names, so we can't simply
automatically check that the names are different and assume that they
aren't the same menu.
This temp variable isn't used anywhere else, and even if it was it's set
to something every time it's used, so there's no risk of this commit
breaking any backwards compatibility.
I assume it was so a dev could mark the spot where they needed to put in
the analogue toggle, and they found a unique yet easy to remember
sequence of characters to Ctrl+F as a marker.
Looks like it was a remnant from the Flash days, and the "delete your
saves if you want to use slowdown" was a bit too mean so it stopped
being a thing in the C++ version.
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.
Previously, it existed solely to count the number of trinkets and
crewmates when loading a level, because we were keeping track of the
amount of them manually, incrementing and decrementing every time a
trinket or crewmate was added or removed, but loading a new level
represented a case that could potentially not be an increment or
decrement.
However, since the amount tracking is now handled automatically, this
function now does nothing, and can be safely removed.
Same principle as removing the separate variable to track number of
collected trinkets. This means it's less error-prone as we're no longer
tracking number of trinkets separately.
In the function that counts the number of trinkets, I would've liked to
have used std::count_if(). However, the most optimal way would require
using a lambda, and lambdas are too new for the C++ standard we're
using. So I just bit the bullet and counted them manually.
game.trinkets is supposed to be correlated with obj.collect, however why
not just count obj.collect directly?
This turns game.trinkets into a function, game.trinkets(), which will
directly count the number of collected trinkets and return it. This will
fix a few corner cases where the number of trinkets can desync with the
actual collection statuses of trinkets.
In order to keep save compatibility with previous versions of VVVVVV,
the game will still write the <trinkets> variable. However, it will not
read the <trinkets> variable from a save file.
It's a bit rude to put the user back at the main menu after toggling
something. Maybe they also wanted to do something else in the menu while
they're toggling MMMMMM, there's no reason to immediately put them back
there.
Whenever you collect a trinket, game.stat_trinkets gets updated (if
applicable) to signify the greatest amount of trinkets you have ever
collected in the game. However, custom levels shouldn't be able to
affect this, as their trinkets are not the same trinkets as the main
game.
It turns out that when the game warps moving platforms, it won't remove
the block from the position before they warped. Eventually, these blocks
will pile up and will never be removed, causing a memory leak.
I noticed that the code for going to the adjacent room when offscreen
and for warping instead if the room is warping was a bit
copy-and-pasted. To clean up the code a bit, there's now 5 separate
checks in gamelogic():
if (map.warpx)
if (map.warpy)
if (map.warpy && !map.warpx)
if (!map.warpy)
if (!map.warpx)
I made sure to preserve the previous weird horizontal warping behavior
that happens with vertical warping (thus the middle one), and to
preserve the frame ordering just in case there's something dependent on
the frame ordering.
The frame ordering is that first it will warp you horizontally, if
applicable, then it will warp you vertically, if applicable. Then if you
have vertical warping only, that weird horizontal warp. Then it will
screen transition you vertically, if applicable. Then it will screen
transition you horizontally, if applicable.
To explain the weird horizontal warp with the vertical warp: apparently
if an entity is far offscreen enough, and if that entity is not the
player, it will be warped horizontally during a vertical warp. The
points at which it will warp is 30 pixels farther out than normal
horizontal warping.
I think someone ran into this before, but my memory is fuzzy. The best I
can recall is that they were probably createentity()ing a high-speed
horizontally-moving enemy in a vertically warping room, only to discover
that said enemy kept warping horizontally.
As a result of the previous commit, textboxclass::clear() is now unused.
textboxclass::firstcreate() was already useless. So remove both those
functions and initialize the values in the textboxclass constructor.
This removes the variables graphics.ntextbox, as well as removing
'active' from each text box object. Thus, all text boxes are really
real, and you don't have to check its 'active' variable.
Something that's slightly annoying is that in order to make the vector
of text boxes be properly used, the text box cannot remove itself.
Because the text box does not know it's in a vector. So move the removal
of the text box to drawgui() instead.
Just like earlier, these are of the form
if (cond1) { if (cond2) { if (cond3) { thing; } } }
and are really annoying to read.
Also this removes the remnants of the 'active' system that have been
replaced with 'if (true)' conditionals in order to not add noise to the
diff.
Previously, it was used in order to clear a block and deactivate it, and
the constructor function simply called clear() in order to not duplicate
code. However, clear() is no longer necessary (just remove the block
from the blocks vector), and so we can put initialization right back in
the constructor function.
It turns out the game engaged in pseudo-UB when removing activity zones,
which got turned into actual UB due to the previous commit.
There were three places where this could happen:
- Pressing ENTER on an activity zone in normal gameplay
- Pressing ENTER on an activity zone in in-editor playtesting (because
the code is duped here)
- Pressing ESC and quitting to menu while standing inside an activity
zone
In all cases, game.activeactivity would still be pointing to a
non-existent activity zone. This activity zone in the previous system
would simply be a block with a false 'active', and in the system where
C++ vectors are used properly, would index past the blocks array.
In fact, it is a bug that when you press ENTER on an activity zone, the
activity zone prompt suddenly turns to black, then immediately
disappears. It was pointing to a block that had its clear() method
called, which is why it was all black, and it was an inactive block!
This commit makes it so pressing ENTER on an activity zone smoothly
fades out the activity zone prompt instead of being sudden black.
This removes the variables obj.nblocks, as well as removing the 'active'
attribute from the block object. Now every block is guaranteed to be
real without having to check the 'active' variable.
Removing a block while iterating now uses the removeblock_iter() macro.
Previously there was an entclass::clear(), and initialization of an
entclass was done by calling clear() in order to not duplicate code. But
now there's no need for an entclass::clear(), and it is in fact unused
(just call entityclass::removeentity() instead), so I'm removing this
function.
I guess these were here earlier when there were 'active' conditionals,
but then I removed those, so now they look weird next to the 'i != j'
conditionals, so I'm removing them.
These would be of the form
if (cond1) { if (cond2) { if (cond3) { thing; } } }
which is really annoying to read and could've been written as
if (cond1 && cond2 && cond3) { thing; }
so that's what I'm fixing here.
There will be another commit later that fixes this but in places related
to blocks.
Not sure why this function is here. It makes sense if you know that the
game will only do certain moving platform things if you already have a
moving platform in the room, however apparently this function has
absolutely nothing to do with it.
This function's sole purpose was to make sure obj.nentity was in sync,
and that obj.nentity-1 pointed to the last 'active' entity in
obj.entities. But now that obj.nentity is removed and we use
obj.entities.size() instead, it is no longer necessary.
In the previous commit, if an if-statement consisted solely of checking
the active attribute of an entity, I temporarily changed it to 'true'
and put a comment to remove it later, because it would add too much
noise to unindent everything in the same commit.
This removes the variables obj.nentity and obj.nlinecrosskludge, as well
as removing the 'active' attribute from the entity class object. Now
every entity you access is guaranteed to be real and you don't have to
check the 'active' variable.
The biggest part of this is changing createentity() to modify a
newly-created entity object and push it back instead of already
modifying an indice in obj.entities.
As well, removing an entity now uses the new obj.removeentity() function
and removeentity_iter() macro.
Also when we switch everything to not use 'active', we'll need this
macro to remove entities while iterating forwards through the vector one
at a time.
Ok, once we switch everything over to not use the 'active' system, it's
easier to read removeentity(t) than it is to read
entities.erase(entities.begin() + t).
This moves the setenemyroom() function onto the entity object itself, so
I can more easily change all 'entities[k].' to 'entity.' in
entityclass::createentity() later.
Additionally, I've had to move the rn() macro from Entity.h to Ent.h, or
else entclass::setenemyroom() won't know what it is.
This moves the setenemy() function onto the entity object itself,
instead of having to give the indice of the entity in obj.entities. This
makes the code more object-oriented so later I can simply change all
'entities[k]' to 'entity.' in entityclass::createentity().
It is an exact duplicate of musicclass::haltdasmusik(), so use that
function instead and update callers. Looks like
musicclass::haltdasmusik() came first, anyway (musicclass::stopmusic()
was only used in editor.cpp).
Looks like musicfade is an unused variable, anyway. I might remove it,
but I have some plans in the future that involve repairing what it was
intended for, so I'll hold off on removing it (and some other unused
variables in Music.cpp) for now.
As discussed earlier, some custom levels have taken advantage of the
fact that songs 0 and 7 loop and also fade in when using PPPPPP while
having an mmmmmm.vvv file present.
The problem is that it would index out-of-bounds if you did this, but
this UB hasn't caused an exception until my change to refactor
script-related vectors by removing their separate length-trackers.
Most of the code was already commented out, and those comments were
removed in earlier commits, but this removes all recording variables
from Game and simplifies the game-gamestate handling in main.cpp a
little bit.
Just a miscellaneous code cleanup.
There's no glitches that take advantage of the previous situation,
namely that 'temp' was a global variable in Logic.cpp and editor.cpp.
Even if there were, it seems like it would easily lead to some undefined
behavior. So it's good to clean this up.
This is the "Behavioral logic", "Basic Physics", and "Collisions with
walls" trio.
They were originally aligned but then I removed global args, thus
misaligning them. So now I'm re-aligning them back again.
Surprisingly not that many. It looks like at one point in development,
damage blocks were created for every single spike in the Tower, before
it was too laggy so they switched to directly checking collision with
the tile instead.
This removes a bunch of commented-out code that was clearly kept from
the Flash version, even though the Flash graphics API is much different
than SDL's. Also removes a bunch of TODOs that either say nothing, or
say something whose meaning has been totally lost to time due to being
completely vague, or something that's already been done and someone
forgot to remove the TODO.
Most of this is telecookie/quickcookie stuff, which was used in the
Flash version, but there's no longer any such thing as a save cookie.
Also one TODO that says to make a function that's now been made.
Unlike, say, the scriptclass i/j/k stuff, these tempstrings are only
purely visual, and there's no known glitches to manipulate them anyway.
Thus I think it's safe to make this cleanup.
It looks like this may have been used earlier in development, judging
from the name, obviously, but right now it seems like it's used as an
error message if a main game level is asked for an invalid room (well,
only two of them - the Lab and Warp Zone). It should probably be
formalized into an error system, if we want to keep teststring, and also
people would never see it anyway because I don't think there's a
reliable and consistent way to trigger loading a non-existent room.
I have seen someone manage to load a non-existent Warp Zone room only
one time, but even then this teststring didn't pop up. So this
teststring doesn't even trigger in the right circumstances.
Also, when it does pop up, as far as I can tell it will stay onscreen,
which is kinda annoying. So I'm just removing this ancient relic from
the code.
To be fair, it was more on the level of entire functions using different
indentation than the surrounding code, but it's not consistent enough
for me to justify leaving it alone.
Looks like this function was created because editorclass::load() takes
in a string by reference, not by value, and thus mutates it afterwards,
so if you passed a string in when you didn't want it to be mutated, bad
things would happen.
However, a better workaround for the above issue would simply to
duplicate the string and pass that string instead, thus the original
string wouldn't be affected.
To reiterate, I just want to remove the mixed indentation that just
randomly pops up in the middle of a file, because it gets annoying.
Thus, the indentation of a particular piece of code should simply match
the surrounding code. And I consider it completely fine that this file
switches from indenting 4-wide spaces to tabs starting from
Graphics::setcol() onwards. I don't think it's worth it to untabify
Graphics::setcol() and below.
This removes all indentation that suddenly switches in the middle of a
function. Most particularly egregious offenses are the ones made by the
person who has 2-wide tabs, but keeps tabbing up to make each
indentation level match up with the 4-wide spaces, so to them (and only
them) it will look just fine, but since by default tabstop is 8-wide,
their lines are pushed off all the way to the right.
This changes something like UtilityClass::String to help.String,
basically. It takes less typing this way, and is a neat effect of having
global args actually be global variables.
Now that it does nothing due to some earlier changes, it's a useless
function that does nothing. (Well, it was already a useless function,
but those earlier changes made it clearer just exactly how useless it
is.) So remove that function and remove all its callsites.
'swfStage' gets set to 'stage' in updategraphicsmode() but... that does
absolutely nothing, because they both contain exactly the same thing.
And these variables aren't referenced anywhere else. So I'm removing
both of these variables.
Although it keeps getting set to true and false in various places, it
never once gets checked, essentially deeming it a variable that's used
but does nothing.
The 'r', 'g', and 'b' arguments do absolutely nothing. Except unlike
Graphics::drawtile(), there's only one version of Graphics::drawtile2(),
so just remove those args and update callers.
The 'r', 'g', and 'b' arguments do absolutely nothing, even though
they're used in the version of Graphics::drawtile() that's more used. So
delete the other version without those extra arguments, and then remove
the extra arguments from the remaining version. And then update callers.
This removes all global args in all functions in titlerender.cpp.
Additionally, all 'dwgfx' has been renamed to 'graphics' in that file
(there are a lot of them, as you might guess).
This commit removes the passing around of global args in the logic
functions. Additionally, all 'dwgfx' has been replaced with 'graphics'
in Logic.cpp.
This removes global arg passing from all functions on editorclass.
Callers have been updated correspondingly. Additionally, all 'dwgfx' has
been replaced with 'graphics' in editor.cpp.
This commit removes all global args from the parameters of each function
on the scriptclass object, and updates all places they are called
accordingly. It also changes all instances of 'dwgfx' to 'graphics' in
Script.cpp.
Interestingly enough, it looks like editor.h depended on Script.h's
class define of the musicclass. I've temporarily placed the class define
in editor.h, but by the end of this patchset it'll be gone.
This removes global args from all functions on the Graphics class.
Callers of those functions in other files have been updated accordingly.
Of course, since Graphics.cpp is already in the Graphics namespace,
I do not need to change all 'dwgfx' to 'graphics' in Graphics.cpp.
This commit removes the global args being passed around from the
function args on the mapclass object, as well as updating all callers in
other files to not have those args. Furthermore, 'dwgfx' has been
renamed to 'graphics' in Map.cpp.
This commit removes all global args from functions on the entityclass
object, and updates the callers of those functions in other files
accordingly (most significantly, the game level files Finalclass.cpp,
Labclass.cpp, Otherlevel.cpp, Spacestation2.cpp, WarpClass.cpp, due to
them using createentity()), as well as renaming all instances of 'dwgfx'
in Entity.cpp to 'graphics'.
I've decided to call dwgfx/game/map/obj/key/help/music the "global args".
Because they're essentially global variables that are being passed
around in args.
This commit removes global args from all functions on the Game class,
and deals with updating the callsites of said functions accordingly. It
also renames all usages of 'dwgfx' in Game.cpp to 'graphics', since the
global variable is called 'graphics' now.
Interesting to note, I was removing the class defines from Game.h, but
it turns out that Graphics.h depends on the mapclass and entityclass
defines from Game.h. And also Graphics.h spelled mapclass wrong (it
forgot the "class") so I just decided to use that existing line instead.
This is only temporary and after all is said and done, at the end of
this pull request those class defines will be gone.
This is a refactor that turns the script-related arrays `ed.sb`, and
`ed.hooklist` into C++ vectors (`script.commands` was already a vector, it was
just misused). The code handling these vectors now looks more like idiomatic
C++ than sloppily-pasted pseudo-ActionScript. This removes the variables
`script.scriptlength`, `ed.sblength`, and `ed.numhooks`, too.
This reduces the amount of code needed to e.g. simply remove something from
any of these vectors. Previously the code had to manually shift the rest of
the elements down one-by-one, and doing it manually is definitely error-prone
and tedious.
But now we can just use fancy functions like `std::vector::erase()` and
`std::remove()` to do it all in one line!
Don't worry, I checked and `std::remove()` is in the C++ standard since at least
1998.
This patch makes it so the `commands` vector gets cleared when
`scriptclass::load()` is ran. Previously, the `commands` vector never actually
properly got cleared, so there could potentially be glitches that rely on the
game indexing past the bounds set by `scriptlength` but still in-bounds in the
eyes of C++, and people could potentially rely on such an exploit...
However, I checked, and I'm pretty sure that no such glitch previously existed
at all, because the only times the vector gets indexed are when `scriptlength`
is either being incremented after starting from 0 (`add()`) or when it's
underneath a `position < scriptlength` conditional.
Furthermore, I'm unaware of anyone who has actually found or used such an
exploit, and I've been in the custom level community for 6 years.
So I think it's fine.
Someone being mean could've overwritten the telesaves of unsuspecting
players, or unlocked a bunch of stuff which they shouldn't have for
those players, using things like the telesave() command and gamestates.
To prevent this, return early in Game::savequick(), Game::savetele(),
and Game::unlocknum() if we are in custommode.
Instead of passing the error codes out of the function, just handle the
errors directly as they happen, and fail gracefully if something goes
wrong instead of continuing.
Whenever you would press Alt+Enter, or Alt+F, or on macOS Command+Enter,
or on macOS Command+F, or F11, the game would print this useless error
message to console, every single time: "Error: failed: " and it would
concatenate SDL_GetError() after it, but most of the time SDL_GetError()
is blank, so it would print just that.
Instead, what the fullscreen shortcut will now do is check the result of
the relevant SDL functions, BEFORE it decides to print an error message.
And when it DOES print an error message, it will be less vague and will
say instead "Error: toggling fullscreen failed: <output of
SDL_GetError()>".
This means Screen::ResizeScreen() and Screen::toggleFullScreen() are now
int-returning functions. Ideally, every function interfacing with SDL
would return an error code, but that's too much for this simple patch.
Additionally, I took the opportunity to clean up the surrounding
formatting of the code a bit, most notably dedenting the
keypress-clearing stuff by one tab level, converting the
shortcut-handling code to spaces, and removing commented-out code.
Each check has been put in its own variable, so the final conditional is
more readable, and the ifdef is no longer right smack in the middle of
an if-statement.
Also the control flow has been changed (the "else" has been removed from
the shortcut-checking conditional) so I could put the variables closer
to the actual conditional itself. I don't think it affects anything,
though.
This patch allows the use of pressing F11 to toggle fullscreen, as well as
allowing the use of Right Command when using the Command+Enter/F shortcut on
macOS. Apparently Alt+Enter isn't the only shortcut to toggle fullscreen,
Alt+F also works, which I didn't know before.
I'm adding F11 as a shortcut because it's a far more natural shortcut to
toggle fullscreen than this Alt+Enter or Alt+F business, which seems to be a
relic mimicking some other games and some Microsoft stuff?
I'm also adding RCommand+Enter/F because I see no reason not to. If you can
use RAlt on non-macOS, why can't you use RCommand on macOS, too?
I also cleaned up the formatting relating to the shortcut code, and made sure
the closing parenthesis was outside the ifdef so my text editor wouldn't
highlight the parenthesis inside the non-macOS ifdef-branch as a dangling
closing parenthesis, because it assumes the one in the branch above is the
actual closing parenthesis and doesn't parse macros.
If you Alt+Tabbed while in fullscreen mode, the game would stay in
fullscreen instead of switching to windowed, but there was a chance it
would EITHER use the same internal resolution which would mismatch the
window resolution (don't know when exactly this happens, but still) and
stay being in an actual windowed mode, OR switch between
fullscreen/windowed every other time you re-focused the window, which is
annoying.
Now, whenever you Alt+Tab in fullscreen, the game will be in windowed
mode, and then when you re-focus it will go back to fullscreen.
Consistently.
Previously, the only way to guarantee that the game actually saved your
unlock.vvv after changing an option, was to ensure you pressed ACTION on
the "quit game" menu option.
This makes Alt+F4 graceful in that pressing it will also save
unlock.vvv, as it should. Now truly UN-graceful ways of exiting the
game, such as SIGSEGV, SIGABRT, or pkill -9 or pkill -15 will not save
unlock.vvv, as should be the case.
Text outline is not drawn on roomtext when you're actually playing the
game, so don't draw the outline in the editor, either.
FIQ mistakenly added text outline to roomtext in
ca9f577fc4.
There's an if-else chain that first deals with figuring out if there's
an entity where your left-click happened, and to do this it uses
edentat(), which returns a sentinel value of -1 if there is NOT an
entity where your cursor is.
It's very important to check that the value returned ISN'T -1 before you
start indexing the 'edentity' vector, since if you DO index it with that
-1, it'll result in Undefined Behavior because you're doing an
out-of-bounds array access.
Now, here's what the if-else chain looked like before:
if(tmp==-1 && ed.free(ed.tilex,ed.tiley)==0)
{
...
}
else if(edentity[tmp].t==1)
The bug here is very subtle but it was an easy oversight. Basically, if
'ed.free' ended up not being zero, control flow would jump to the next
"else if" over, which then ends up asking for the -1th index of
'edentity', which is Undefined Behavior.
This undefined behavior has now resulted in a crash on my system after
TerryCavanagh/VVVVVV#172, due it shuffling things around juuuuust enough
such that this UB would end up resulting in a segfault instead of
chugging along and working fine. For me and my system, this meant that
if my first left-click in the editor upon opening the game was me
placing down a tile and not placing down an entity, the game would
crash. But, it would be fine if I first placed down an entity and then
afterwards placed down tiles, because it's UB.
And I'm almost certain this was the cause of the very strange bug where
you couldn't hold down left-click for the foreground-placing tool (but
you COULD for the background-placing tool) that seemed to occur most
often on Windows (TerryCavanagh/VVVVVV#25).
The solution to this is to stick in another conditional in the tree
before any indexing occurs, such that there's no way any other
conditionals with the indexing in the conditional tree could end up
being hit. In summary, the if-else chain looks like this now:
if(tmp==-1 && ed.free(ed.tilex,ed.tiley)==0)
{
...
}
else if(tmp == -1)
{
//Important! Do nothing, or else Undefined Behavior will happen
}
else if(edentity[tmp].t==1)
This turns the array 'edentity' into a proper vector, and removes the need to
use a separate length-tracking variable and manually keep track of the actual
amount of edentities in the level by using the long-winded
'EditorData::GetInstance().numedentities'. This manual tracking was more
error-prone and much less maintainable.
editorclass::naddedentity() has been removed due to now functionally being the
same as editorclass::addedentity() (there's no more
'EditorData::GetInstance().numedentities' to not increment) and for also being
unused in the first place.
editorclass::copyedentity() has been removed because it was only used to shift
the rest of the edentities up manually, but now that we let C++ do all the
hard work it's no longer necessary.
This refactors the roomtext code to (1) not use ad-hoc objects and (2)
not use a separate length-tracking variable to keep track of the actual
amount of roomtext in a room.
What I mean by ad-hoc object is, instead of formally creating a
fully-fledged struct or class and storing one vector containing that
object, this game instead hacks together an object by storing each
attribute of an object in different vectors.
In the case of roomtext, instead of making a Roomtext object that has
attributes 'x', 'y', and 'text', the 'text' attribute of each is stored
in the vector 'roomtext', the 'x' attribute of each is stored in the
vector 'roomtextx', and the 'y' attribute of each is stored in the
vector 'roomtexty'. It's only an object in the sense that you can grab
the attributes of each roomtext by using the same index across all three
vectors.
This makes it somewhat annoying to maintain and deal with, like when I
wanted add sub-tile positions to roomtext in VVVVVV: Community Edition.
Instead of being able to add attributes to an already-existing
formalized Roomtext object, I would instead have to add two more
vectors, which is inelegant. Or I could refactor the whole system, which
is what I decided to do instead.
Furthermore, this removes the separate length-tracking variable
'roomtextnumlines', which makes the code much more easy to maintain and
deal with, as the amount of roomtext is naturally tracked by C++ instead
of us having to keep track of the actual amount of roomtext manually.
This fixes a source of undefined behavior, where the int returned by
ss_toi() would be random garbage memory if the string passed into it
would be empty. That's because if the string is empty, there are no
characters to parse, so nothing simply gets put into x.
The easiest way to pass an empty string in to ss_toi() would be to use
script commands with empty arguments.
The problem was that the code seemed to be wrongly copy-pasted from the
code for generating the trinket-found text boxes (to the point where
even the comment for the crewmate-found text boxes didn't get changed
from "//Found a trinket!").
For the trinket-found text boxes, they use y-positions 85 and 135 if not
in flip mode, and y-positions 105 and 65 if the game IS in flip mode.
These text boxes are positioned correctly in flip mode.
However, for the crewmate-found text boxes, they use y-positions 85 and
135 if not in flip mode, as usual, but they use y-positions 105 and 135
if the game IS in flip mode. Looks like someone forgot to change the
second y-position when copy-pasting code around.
Which is actually a bit funny, because I can conclude from this that it
seems like the code to position these text boxes in flip mode was
bolted-on AFTER the initial code of these text boxes was written.
I can also conclude (hot take incoming) that basically no one actually
ever tested this game in flip mode (but that was already evident, given
TerryCavanagh/VVVVVV#140, less strongly TerryCavanagh/VVVVVV#141, and
TerryCavanagh/VVVVVV#142 is another flip-mode-related bug which I guess
sorta kinda doesn't really count since text outline wasn't enabled until
2.3?).
So I fixed the second y-position to be 65, just like the y-position the
trinket text boxes use. I even took the opportunity to fix the comment
to say "//Found a crewmate!" instead of "//Found a trinket!".
Previously, when MMMMMM is installed but the user is using PPPPPP, niceplay would still restart the song even if it's the same. That has been fixed. In addition, Plenary and Path Complete no longer loop when MMMMMM is installed but PPPPPP is in use.
This fixes another way you could end up typing on a non-existent line in
the script editor.
In a script with only 1 line, which is empty, the game would let you
press backspace on it, removing the line. This results in you typing on
a non-existent line.
You will keep typing on it until you either close the script or press
Up. If you press Up, you will be unable to get back to the non-existent
line, for it doesn't exist - but the text you typed on the non-existent
line will still be there, until you close the script and re-open it.
