This makes it so room names are no longer pointers to someone else's
memory, and instead to set them you use `mapclass::setroomname`. If the
string is short enough to fit in a static, no-alloc buffer, then it gets
copied there. Otherwise, a new heap allocation is made that duplicates
the string, and the new pointer is used instead.
This makes it possible for room names to contain arbitrary data whose
origin is temporary (e.g. from a script command that could be added in
the future).
It's becoming pretty clear that the size of the map is important enough
to be queried a lot, but each time it's something like `map.custommode ?
map.customwidth : 20` and `map.custommode ? map.customheight : 20` which
is not ideal because of copy-pasting.
Furthermore, even `map.customwidth` and `map.customheight` are just
duplicates of `cl.mapwidth` and `cl.mapheight`, which are only set in
`customlevelclass::generatecustomminimap`. This is a bit annoying if you
want to, say, add checks that depend on the width and height of the
custom map in `mapclass::initcustommapdata`, but `map.customwidth` and
`map.customheight` are out of date because `generatecustomminimap`
hasn't been called yet. And doing the ternary there requires a `#ifndef
NO_CUSTOM_LEVELS` to reference `cl.mapwidth` and `cl.mapheight` which is
just awful.
So I'm axing `map.customwidth` and `map.customheight`, and I'm axing all
the ternaries that are duplicating the source of truth in
`MapRenderData`. Instead, there will just be one function to call for
the width and height, `mapclass::getwidth` and `mapclass::getheight`,
and everyone can simply call those without needing to do ternaries or
duplication.
There's always been a bit of an inconsistency in the game where enabling
invincibility would make spikes so solid that enemies and moving
platforms would treat spikes as solid and bounces off of them.
This fixes that by adding an `invincible` parameter to collision
functions, so the functions will only treat spikes as solid if that
parameter is true, and the parameter passed will only be true if it's
called for an entity that is a humanoid and invincibility mode is
enabled.
Also, for clarity, `spikecollide` is renamed to `towerspikecollide`
because it's only used for tower spikes. And as a small optimization,
`checktowerspikes` returns early if invincibility mode is enabled.
There's really no need to put the y-multiplication in a lookup table.
The compiler will optimize the multiplication better than putting it in
a lookup table will.
To improve readability and to hardcode things less, the new
SCREEN_WIDTH_TILES and SCREEN_HEIGHT_TILES constant names are used, as
well as adding a new TILE_IDX macro to calculate the index of a tile in
a concatenated-rows (row-major in formal parlance) array. Also, tile
numbers are stored in a temporary variable to improve readability as
well (no more copy-pasting `contents[i + vmult[j]]` over and over
again).
Since those are all downstream recipients of either static storage or
memory that doesn't move for the duration of the custom level, it's okay
to make these be `const char*`s without having to redo any of the RAII
memory management.
mapclass::currentarea() is included in this as well. I also cleaned up
Tower.cpp's headers to fix some transitive includes because I was
removing UtilityClass.h includes from all other level files too.
The "Untitled room" names no longer show any coordinates, because doing
so would require complicated memory management that's completely
unneeded. No one will ever see them, and if they do they already know
they have a problem anyway. The only time they might be able to see them
is if they corrupted the areamap, but this was only possible in 2.2 and
previous by dying outside the room deaths array in Outside Dimension
VVVVVV, which has since been patched out. Besides, sometimes the
"Untitled room" gets overwritten by something else anyway (especially in
Finalclass.cpp), so it really, really doesn't matter.
Companions would not spawn if you didn't load the current room via a
room transition. This meant that companions wouldn't spawn if you loaded
a save file with a companion, at least not until you moved to a
different room and triggered a screen transition. But most importantly,
it meant that the Intermission 1 supercrewmate would never spawn,
because going to Intermission 1 does a straight gotoroom, and does not
do a room transition.
Turns out the roomchange refactor broke things, because of course it
did. The companion logic was implicitly relying on that bool to be set,
because...? Either way, it doesn't make sense. Using roomchange implied
that the code wanted to be ran only when doing a room transition, which
is clearly not the case here. The best thing to do here is to just move
it to a separate function that gets called at the end of
mapclass::gotoroom().
Ever since tilesheets got expanded, custom levels could use as many
tiles as they wanted, as long as it fit under the 32-bit signed integer
limit.
Until 6c85fae339 happened and they were
reduced to 32,767 tiles.
So I'm being generous again and changing the type of the contents array
(in mapclass and editorclass) back to int. This won't affect the
existing tilemaps of the main game, they'll still stay short arrays. But
it means level makers can use 2 billion tiles once again.
This can happen if you select an option in a menu that (A) returns to
the previous menu and (B) saves settings. If the settings save fails,
this will create another menu on the same frame that cycles the tower BG
after it's already been cycled for that frame. Examples are the slowdown
and glitchrunner menus.
I could fix this by creating a new function that copy-pastes all of
Game::savestatsandsettings_menu() except for the map.nexttowercolour()
at the end. But that's copy-pasting code.
Instead what I've done is added a variable to signal if the color has
already been cycled this frame, so we don't cycle it again. This also
covers cases of possible double-cycling in the future as well.
Tower backgrounds have a bypos and bscroll. bypos is just the y-position
of the background, and bscroll is the amount of pixels to scroll the
background by on each frame, which is used to scroll it (if it's not
being redrawn) and for linear interpolation.
For the tower background (and not the title background), bypos is
map.ypos / 2, and bscroll is (map.ypos - map.oldypos) / 2. However,
usually bscroll gets assigned at the same time bypos is incremented or
decremented, so you never see that calculation explicitly - except in
the previous commit, where I worked out the calculation because the
change in y-position isn't a known constant.
Having to do all these calculations every time introduces the
possibility of errors where you forget to do it, or you do it wrongly.
But that's not even the worst; you could cause a linear interpolation
glitch if you decide to overwrite bscroll without taking into account
map.oldypos and map.ypos.
So that's why I'm adding a function that automatically updates the tower
background, using the values of map.oldypos and map.ypos, that is used
every time map.ypos is assigned. That way, we have to write less code,
you can be sure that there's no place where we forget to do the
calculations (or at least it will be glaringly obvious) or we do it
wrongly, and it plays nicely with linear interpolation. This also
replaces every instance where the manual calculations are done with the
new function.
So... I did see that map.ypos was a float when I added over-30-FPS mode,
because map.oldypos wasn't there before... I'm guessing that I kind of
just ignored it at the time. But, c'mon, map.ypos and map.oldypos are
always treated as ints, so there's literally no reason for them to be
actually floats in reality. I didn't even know they were anything other
than ints until I checked Map.h.
This makes it easier to add bounds checks to all accesses of
map.explored. Also, all manually-written existing bounds checks have
been removed, because they're going to go into the new getters and
setters.
The getter is mapclass::isexplored() and the setter is
mapclass::setexplored().
Apparently in C, if you have `void test();`, it's completely okay to do
`test(2);`. The function will take in the argument, but just discard it
and throw it away. It's like a trash can, and a rude one at that. If you
declare it like `void test(void);`, this is prevented.
This is not a problem in C++ - doing `void test();` and `test(2);` is
guaranteed to result in a compile error (this also means that right now,
at least in all `.cpp` files, nobody is ever calling a void parameter
function with arguments and having their arguments be thrown away).
However, we may not be using C++ in the future, so I just want to lay
down the precedent that if a function takes in no arguments, you must
explicitly declare it as such.
I would've added `-Wstrict-prototypes`, but it produces an annoying
warning message saying it doesn't work in C++ mode if you're compiling
in C++ mode. So it can be added later.
These variables basically serve no purpose. map.customx and map.customy
are clearly never used. map.finalx and map.finaly, on the other hand,
are basically always game.roomx and game.roomy respectively if
map.finalmode is on, and if it's off, then they don't matter.
Also, there are some weird and redundant variable assignments going on
with these; most notably in map.gotoroom(), where rx/ry (local
variables) get assigned to finalx/finaly, then finalx/finaly get
assigned to game.roomx/game.roomy, then finalx/finaly get assigned to
rx/ry. If finalx/finaly made a difference, then there'd be no need to
assign finalx/finaly back to rx/ry. So it makes the code clearer to
remove these weird bits of code.
This fixes a bug where if you entered a tower before watching the
credits sequence, the credits sequence would have mismatched text and
background colors.
This bug happened because entering a tower modified the r/g/b attributes
of mapclass, and updated graphics.towerbg, without updating
graphics.titlebg too. Then gamecompleterender() uses the r/g/b
attributes of mapclass.
The solution is to put the r/g/b attributes on TowerBG instead. That
way, entering a tower will only modify the r/g/b attributes used to
render towers, and won't affect the r/g/b attributes used to render the
credits sequence.
Additionally, I also de-duplicated the case-switch that updated the
r/g/b attributes based off of the current colstate, because it got
copy-pasted twice, leading to three instances of one piece of code.
When I did #567, I didn't test it. And I should have tested it, because
it made the player invisible. This is because map.resetplayer() also
sets the invis attribute of the player to true as well, and I only undid
it setting game.lifeseq to 10.
So instead, I'll just add a flag to map.resetplayer() that by default
doesn't set game.lifeseq or the player's invis attribute. And I tested
it this time, and it works fine. I tested both respawning after death
and exiting to the menu and loading in the game again.
Now that tower, title, and horizontal/veritcal warp backgrounds all use
separate buffers, there's no longer any need to temporarily store
variables as a workaround for the buffers stepping on each other.
Previously, the tower background was controlled by a disparate set of
attributes on Graphics and mapclass, and wasn't really encapsulated. (If
that's what that word means, I don't particularly care about
object-oriented lingo.) But now, all relevant things that a tower
background has has been put into a TowerBG struct, so it will be easy to
make multiple copies without having to duplicate the code that handles
it.
Yet another set of temporary variables is on a global class when they
shouldn't be. These two are only used in tower background functions and
are never used anywhere else, so they're clearly temporaries.
This function was only used in assigments to mapclass::towercol. But
that variable is unused, and has been removed, so after removing that
variable, this one is unused, too.
By "unnecessary qualifiers to self", I mean something like using the
'game.' qualifier for a variable on the Game class when you're inside a
function on the Game class itself. This patch is to enforce consistency
as most of the code doesn't have these unnecessary qualifiers.
To prevent further unnecessary qualifiers to self, I made it so the
extern in each header file can be omitted by using a define. That way,
if someone writes something referring to 'game.' on a Game function,
there will be a compile error.
However, if you really need to have a reference to the global name, and
you're within the same .cpp file as the implementation of that object,
you can just do the extern at the function-level. A good example of this
is editorinput()/editorrender()/editorlogic() in editor.cpp. In my
opinion, they should probably be split off into their own separate file
because editor.cpp is getting way too big, but this will do for now.
Okay, so basically here's the include layout that this game now
consistently uses:
[The "main" header file, if any (e.g. Graphics.h for Graphics.cpp)]
[blank line]
[All system includes, such as tinyxml2/physfs/utfcpp/SDL]
[blank line]
[All project includes, such as Game.h/Entity.h/etc.]
And if applicable, another blank line, and then some special-case
include screwy stuff (take a look at editor.cpp or FileSystemUtils.cpp,
for example, they have ifdefs and defines with their includes).
Including a header file inside another header file means a bunch of
files are going to be unnecessarily recompiled whenever that inner
header file is changed. So I minimized the amount of header files
included in a header file, and only included the ones that were
necessary (system includes don't count, I'm only talking about includes
from within this project). Then the includes are only in the .cpp files
themselves.
This also minimizes problems such as a NO_CUSTOM_LEVELS build failing
because some file depended on an include that got included in editor.h,
which is another benefit of removing unnecessary includes from header
files.
This removes around megabyte from the binary, so a stripped -Og binary
went from 4.0 megabytes to 2.9 megabytes, and an unstripped -O0 binary
went from 8.1 megabytes to 7.1 megabytes, which means I can now finally
upload an unstripped -O0 binary to Discord without having to give money
to Discord for their dumb Nitro thing or whatever.
map.contents always has 1200 tiles in it, there's no reason it should be
a vector.
This is a big commit because it requires changing all the level classes
to return a pointer to an array instead of returning a vector. Which
took a while for me to figure out, but eventually I did it. I tested to
make sure and there's no problems.
They're always fixed-size anyways, there's no need for them to be
vectors.
Also used the new INBOUNDS_ARR() macro for the map.explored bounds
checks in Script.cpp, and made map.explored a proper bool array instead
of an int array.
This patch is very kludge-y, but at least it fixes a semi-noticeable
visual issue in custom levels that use internal scripts to spawn
entities when loading a room.
Basically, the problem here is that when the game checks for script
boxes and sets newscript, newscript has already been processed for that
frame, and when the game does load a script, script.run() has already
been processed for that frame.
That issue can be fixed, but it turns out that due to my over-30-FPS
game loop changes, there's now ANOTHER visible frame of delay between
room load and entity creation, because the render function gets called
in between the script being loaded at the end of gamelogic() and the
script actually getting run.
So... I have to temporary move script.run() to the end of gamelogic()
(in map.twoframedelayfix()), and make sure it doesn't get run next
frame, because double-evaluations are bad. To do that, I have to
introduce the kludge variable script.dontrunnextframe, which does
exactly as it says.
And with all that work, the two-frame (now three-frame) delay is fixed.
Since the exact same tower background is also used on the menu, we need
to save the current state of the background when entering the menu
(before overwriting it), and then put it back when we're done. Maybe we
ought to separate the in-game and menu tower backgrounds...
This also fixes a semi-hilarious bug where you could make Panic Room go
in the other direction by simply going to the options menu in-game.
This is accomplished by adding convenience functions
mapclass::bg_to_kludge() and mapclass::kludge_to_bg().
By "hidden names", I'm referring to "Dimension VVVVVV" and "The Ship"
popping up on the quit/pause/teleporter screens, even though those rooms
don't have any roomnames.
Apparently my commit to fix roomname re-draw bleed on the
quit/pause/teleporter screens exposed yet another hardreset()-caused
bug. The issue here is that since hardreset() sets game.roomx and
game.roomy to 0, map.area() will no longer work properly, and since the
hidden roomname check is based on map.area(), it will no longer display
"Dimension VVVVVV" or "The Ship" once you press ACTION to quit. It used
to do this due to the re-draw bleed, but now it doesn't.
I saw that roomnames didn't get reset in hardreset(), so the solution
here is to re-factor hidden names to be an actual variable, instead of
being implicit. map.hiddenname is a variable that's set in
mapclass::loadlevel(), and if isn't empty, it will be drawn on the
quit/pause/teleporter screens. That way it will still display "Dimension
VVVVVV" and "The Ship" when you press ACTION to quit to the menu.
EDIT: Since PR #230 got merged, this commit is no longer strictly
necessary, but it's still good to refactor hidden names like this.
The only class that actually needs its i/j/k kept is scriptclass,
because some custom levels rely on it for creating custom activity
zones. So I haven't touched that.
Other than that, there's no chance that anything important relies on
i/j/k in any other class. For that to be the case, it would have to use
i/j/k without initializing it beforehand, and that can simply be
detected by removing the attribute from the header file and seeing where
the compiler complains. And the compiler complains only about cases
where it's initialized first. (Note that due to this check, I *haven't*
removed Graphics's `m` as it precisely does exactly this, using it
without initializing it first.)
Interestingly enough, otherlevelclass and towerclass have unused i/k
variables for whatever reason.
Previously, it was used to parse 30 strings whenever loading a room. But
now it's no longer used since we just assign the tilemap to the vector
directly.
This removes map.numshinytrinkets in favor of using
map.shinytrinkets.size(). Having automatic length tracking is much less
error-prone and less tedious.
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 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.
