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.
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.
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 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.
The problem with flipme() was that it WAS properly reflecting
("reflecting" as in mirroring over a given line) the text box over the
line y=120, BUT it forgot to account for the height of the text box.
Thus, the text box position would be off by the length of its own
height. And when the text box got taller, this offset would worsen and
worsen.
The game uses magic values x=-500 and y=-500 to indicate when a text box
should be centered horizontally or vertically. It does this for x=-1
too, but it's buggy because it only looks at the first line of the text
box to center it. In this commit I fix it so that it will look at all of
the lines of the text box to center it instead.
This fixes a bug where if warpdir() was used during in-editor
playtesting, the changed warp direction would persist even when leaving
playtesting.
This would be very annoying to correct back every time you playtested
and warpdir() was used, so I've added some kludge to store the actual
warp direction of each room when entering playtesting, and then set the
warp directions back when leaving playtesting.
This has two benefits:
(1) The game uses less resources when it is asked to gotoroom to the
same room because it is no longer redrawing the warp background
every single frame, which is very wasteful.
(2) The warp background no longer freezes or flickers if the player is
standing inside a gotoroom script box (which calls gotoroom every
frame or every other frame, because every time the gotoroom happens
the script box gets reloaded).
I ran the game through Valgrind to catch various issues.
One thing caught my attention -- map.resumedelay. This is
used by The Tower/etc to add a delay before the game is
resumed (probably for camera controls delaying it) for
spawning the player. This variable was uninitialized. Notably,
if I explicitly set it to 592851 or similar, it reproduces the
bug, even if I cannot reproduce it with my typical compilation
flags. So fixing this by initializing it to 0, alongside some
other Valgrind warnings, should fix the problem entirely.
Previously, if it was called in a custom level, it would say "out of
Twenty" no matter what, even if the level had zero trinkets. This commit
fixes that.
This fixes an issue where you could softlock the game if you exited
playtesting mode by pressing Esc while a "- Press ACTION to advance text
-" prompt was onscreen, then re-entered playtesting and then started any
script.
The "- Press ACTION to advance text -" prompt is most directly
controlled by game.advancetext, but when it appears game.pausescript is
usually set as well. You need to have both variables on at the same time
in order to press ACTION. If only advancetext is on, then you won't be
able to flip but can still move around, but if only pausescript is on,
then the game softlocks because the only way you can turn pausescript
off is by pressing ACTION, but the game will only let you press ACTION
if *both* advancetext and pausescript are on.
This fixes a bug in the editor where if you had cutscene bars active
while exiting playtesting, when you re-entered playtesting, the bars
would do their closing animation even though they should be already
gone.
If you're in the room being targeted when a `warpdir()` command is run,
and it sets the warp direction to none (warp dir 0), and if you're in a
Lab or Warp Zone room, the background will be set to the wrong one,
because it will always set the background to the stars-going-left
background, instead of setting it to the Lab background or the
stars-going-up background.
However, this is only a visual glitch, and is a temporary one, because
if you manage to trigger a `gotoroom()` on the room, it will get set to
its proper background.
This commit makes it so if you're in a Lab room, the background gets set
to the Lab background, and if you're in a Warp Zone room, the background
gets set to the stars-going-up background.
There are three map-related vectors that need to be reset in hardreset:
`map.roomdeaths`, `map.roomdeathsfinal`, and `map.explored`. All three
of these vectors use the concatenated rows system, whereby each room is
given a room number, calculated by doing X + Y*20, and this becomes
their index in each vector.
There's a double-nested for-loop to handle resetting all of these, where
the outer for-loop iterates over the Y-axis and the inner for-loop
iterates over the X-axis, but only `map.explored` is properly reset.
That's because it's the only vector that properly indexes using X +
Y*20. The other vectors reset using X, so previously, only the first row
of `map.roomdeaths` and `map.roomdeathsfinal` got reset, corresponding
with only the first row of rooms in both Dimension VVVVVV and Outside
Dimension VVVVVV getting reset.
This commit makes sure that both get reset properly.
There are two main problems with flipgravity():
1. It doesn't work for an already-flipped crewmate.
2. It doesn't work on the player.
This commit addresses both of those issues.
Resizing the vector does the same thing that the loops did, it changes
the size for the vector and initializes it with default-constructed
elements (or 0 or its equivalent for POD types).
Where a specific value is needed, it is set with the second
parameter of resize().
