One of these days, I need to get around to running Include What You Use
on this codebase. Until then, while I was working on #624, I noticed
these; I'm removing them now.
Note that level dir listing still uses plenty of STL (including the end
product - the `LevelMetaData` struct - which, for the purposes of 2.3,
is okay enough (2.4 should remove STL usage entirely)); it's just that
the initial act of iterating over the levels directory no longer takes
four or SIX(!!!) heap allocations (not counting reallocations and other
heap allocations this patch does not remove), and no longer does any
data marshalling.
Like text splitting, and binary blob extra indice grabbing, the current
approach that FILESYSTEM_getLevelDirFileNames() uses is a temporary
std::vector of std::strings as a middleman to store all the filenames,
and the game iterates over that std::vector to grab each level metadata.
Except, it's even worse in this case, because PHYSFS_enumerateFiles()
ALREADY does a heap allocation. Oh, and
FILESYSTEM_getLevelDirFileNames() gets called two or three times. Yeah,
let me explain:
1. FILESYSTEM_getLevelDirFileNames() calls PHYSFS_enumerateFiles().
2. PHYSFS_enumerateFiles() allocates an array of pointers to arrays of
chars on the heap. For each filename, it will:
a. Allocate an array of chars for the filename.
b. Reallocate the array of pointers to add the pointer to the above
char array.
(In this step, it also inserts the filename in alphabetically -
without any further allocations, as far as I know - but this is a
COMPLETELY unnecessary step, because we are going to sort the list
of levels by ourselves via the metadata title in the end anyways.)
3. FILESYSTEM_getLevelDirFileNames() iterates over the PhysFS list, and
allocates an std::vector on the heap to shove the list into. Then,
for each filename, it will:
a. Allocate an std::string, initialized to "levels/".
b. Append the filename to the std::string above. This will most
likely require a re-allocation.
c. Duplicate the std::string - which requires allocating more memory
again - to put it into the std::vector.
(Compared to the PhysFS list above, the std::vector does less
reallocations; it however will still end up reallocating a certain
amount of times in the end.)
4. FILESYSTEM_getLevelDirFileNames() will free the PhysFS list.
5. Then to get the std::vector<std::string> back to the caller, we end
up having to reallocate the std::vector again - reallocating every
single std::string inside it, too - to give it back to the caller.
And to top it all off, FILESYSTEM_getLevelDirFileNames() is guaranteed
to either be called two times, or three times. This is because
editorclass::getDirectoryData() will call editorclass::loadZips(), which
will unconditionally call FILESYSTEM_getLevelDirFileNames(), then call
it AGAIN if a zip was found. Then once the function returns,
getDirectoryData() will still unconditionally call
FILESYSTEM_getLevelDirFileNames(). This smells like someone bolting
something on without regard for the whole picture of the system, but
whatever; I can clean up their mess just fine.
So, what do I do about this? Well, just like I did with text splitting
and binary blob extras, make the final for-loop - the one that does the
actual metadata parsing - more immediate.
So how do I do that? Well, PhysFS has a function named
PHYSFS_enumerate(). PHYSFS_enumerateFiles(), in fact, uses this function
internally, and is basically just a wrapper with some allocation and
alphabetization.
PHYSFS_enumerate() takes in a pointer to a function, which it will call
for every single entry that it iterates over. It also lets you pass in
another arbitrary pointer that it leaves alone, which I use to pass
through a function pointer that is the actual callback.
So to clarify, there are two callbacks - one callback is passed through
into another callback that gets passed through to PHYSFS_enumerate().
The callback that gets passed to PHYSFS_enumerate() is always the same,
but the callback that gets passed through the callback can be different
(if you look at the calling code, you can see that one caller passes
through a normal level metadata callback; the other passes through a zip
file callback).
Furthermore, I've also cleaned it up so that if editorclass::loadZips()
finds a zip file, it won't iterate over all the files in the levels
directory a third time. Instead, the level directory only gets iterated
over twice - once to check for zips, and another to load every level
plus all zips; the second time is when all the heap allocations happen.
And with that, level list loading now uses less STL templated stuff and
much less heap allocations.
Also, ed.directoryList basically has no reason to exist other than being
a temporary std::vector, so I've removed it. This further decreases
memory usage, depending on how many levels you have in your levels
folder (I know that I usually have a lot and don't really ever clean it
up, lol).
Lastly, in the callback passed to PhysFS, `builtLocation` is actually no
longer hardcoded to just the `levels` directory, since instead we now
use the `origdir` variable that PhysFS passes us. So that's good, too.
If PHYSFS_mountHandle() failed to mount a zip file, we would print
PhysFS's error message straight, without any surrounding context. This
seems a little weird, and doesn't maximize understanding for readers;
I've made it so now the error message is "Could not mount <zip file>:
<PhysFS error>".
The current way "arrays" from XML files are loaded (before this commit
is applied) goes something like this:
1. Read the buffer of the contents of the tag using TinyXML-2.
2. Allocate a buffer on the heap of the same size, and copy the
existing buffer to it. (This is what the statement `std::string
TextString = pText;` does.)
3. For each delimiter in the heap-allocated buffer...
a. Allocate another buffer on the heap, and copy the characters from
the previous delimiter to the delimiter you just hit.
b. Then allocate the buffer AGAIN, to copy it into an std::vector.
4. Then re-allocate every single buffer YET AGAIN, because you need to
make a copy of the std::vector in split() to return it to the caller.
As you can see, the existing way uses a lot of memory allocations and
data marshalling, just to split some text.
The problem here is mostly making a temporary std::vector of split text,
before doing any actual useful work (most likely, putting it into an
array or ANOTHER std::vector - if the latter, then that's yet another
memory allocation on top of the memory allocation you already did; this
memory allocation is unavoidable, unlike the ones mentioned earlier,
which should be removed).
So I noticed that since we're iterating over the entire string once
(just to shove its contents into a temporary std::vector), and then
basically iterating over it again - why can't the whole thing just be
more immediate, and just be iterated over once?
So that's what I've done here. I've axed the split() function (both of
them, actually), and made next_split() and next_split_s().
next_split() will take an existing string and a starting index, and it
will find the next occurrence of the given delimiter in the string. Once
it does so, it will return the length from the previous starting index,
and modify your starting index as well. The price for immediateness is
that you're supposed to handle keeping the index of the previous
starting index around in order to be able to use the function; updating
it after each iteration is also your responsibility.
(By the way, next_split() doesn't use SDL_strchr(), because we can't get
the length of the substring for the last substring. We could handle this
special case specifically, but it'd be uglier; it also introduces
iterating over the last substring twice, when we only need to do it
once.)
next_split_s() does the same thing as next_split(), except it will copy
the resulting substring into a buffer that you provide (along with its
size). Useful if you don't particularly care about the length of the
substring.
All callers have been updated accordingly. This new system does not make
ANY heap allocations at all; at worst, it allocates a temporary buffer
on the stack, but that's only if you use next_split_s(); plus, it'd be a
fixed-size buffer, and stack allocations are negligible anyway.
This improves performance when loading any sort of XML file, especially
loading custom levels - which, on my system at least, I can noticeably
tell (there's less of a freeze when I load in to a custom level with
lots of scripts). It also decreases memory usage, because the heap isn't
being used just to iterate over some delimiters when XML files are
loaded.
Contents and scripts should be reset in editorclass::reset(); there's no
reason to reset them again right before you load them from an XML file
in editorclass::load().
Additionally, the resets now consistently use SDL_zeroa() (for contents)
and scriptclass::clearcustom() (for scripts).
I'm partial to slash-asterisk-style comments, so I'll use those here.
Also, having a space after the start of comments is good. I've also
removed the "Add the script if we have a preceding header" comments
since it can be inferred by reading the surrounding code.
Instead of checking the length() of an std::string, just check if
pText[0] is equal to '\0'.
This will have to be done anyway, because I'm going to get rid of the
std::string allocation here, and I noticed this inefficiency in the
indentation, so I'm going to remove it.
The actual unindent will be done in the next commit.
Even if split() didn't use the STL, using this function here is a bit
unnecessary, because a simple SDL_strchr() suffices. Refactoring split()
to not use the STL will break this caller anyway, so I might as well
just refactor this to not use split() in the first place.
This refactor also properly checks if the inputs are valid integers. And
since split() is no longer used, it also rejects inputs ending with a
trailing comma as being invalid, too; this didn't happen previously.
It's intentional that I used is_number() here instead of
is_positive_num(), thus accepting negative numbers; in the future it
might be possible to have negative room coordinates.
This fixes memory leaking every single time a file gets loaded(!) when
the list of custom levels gets loaded(!!!), which Valgrind reports. This
memory leak is completely my bad; 2.2 properly frees the loaded file,
and VCE uses an std::unique_ptr - which I decided to ignore and not
think about why it would be there.
It's safe to do this free after uMem gets copied into std::string;
although, in the future, I *am* thinking about refactoring this function
(and the tag finder function) to not use std::strings, and I'll have to
be careful to make sure that the memory management with the file is
correct when I do so.
MSVC complains about these, doesn't seem like GCC does. These can be
safely removed because they're unreachable, and they always follow a
case-switch or similar that has a default case which this code is a
duplicate of anyway. (Unless it isn't, in which case all the better to
remove it, becausee otherwise it looks misleading or confusing to casual
glances at the code.)
find_tag() would commit out-of-bounds indexing if someone made a level
file with malformed XML entity encodings in the metadata tags.
This would happen if the end of the string followed immediately after an
ampersand and hash, or if there wasn't a semicolon ending an XML entity.
Valgrind complains about these, so I've fixed it.
The previous person who wrote this (a girl named Misa) clearly didn't
understand the reason why you couldn't compare line[line.length()-1]
directly to a string literal. It's because the former is a char, and the
latter is a pointer to a char. Both are ints, so it compiles fine, but
it doesn't do what you want it to.
Why not just make the latter a char instead of a string literal? Well,
because you can, but also I clearly didn't think this through earlier,
so that's why I didn't do it in the first place.
But this is fixed now.
Retextured checkpoints have always been in the game, but clicking on
them in the editor would lead to them losing their retextured-ness. So,
checkpoints should be left alone if their p1 isn't either 0 or 1. Also,
they don't show up properly in the editor, so that's fixed, too.
Retextured and flipped terminals were added in 2.3, and show up properly
in-game, but don't properly show up in the editor, either. So now they
show up in the editor. Additionally, clicking on them will flip the
terminal as well, but only if its p1 is 0 or 1, just like checkpoints
now do.
There are multiple different exit paths to the main menu. In 2.2, they
all had a bunch of copy-pasted code. In 2.3 currently, most of them use
game.quittomenu(), but there are some stragglers that still use
hand-copied code.
This is a bit of a problem, because all exit paths should consistently
have FILESYSTEM_unmountassets(), as part of the 2.3 feature of per-level
custom assets. Furthermore, most (but not all) of the paths call
script.hardreset() too, and some of the stragglers don't. So there could
be something persisting through to the title screen (like a really long
flash/shake timer) that could only persist if exiting to the title
screen through those paths.
But, actually, it seems like there's a good reason for some of those to
not call script.hardreset() - namely, dying or completing No Death Mode
and completing a Time Trial presents some information onscreen that
would get reset by script.hardreset(), so I'll fix that in a later
commit.
So what I've done for this commit is found every exit path that didn't
already use game.quittomenu(), and made them use game.quittomenu(). As
well, some of them had special handling that existed on top of them
already having a corresponding entry in game.quittomenu() (but the path
would take the special handling because it never did game.quittomenu()),
so I removed that special handling as well (e.g. exiting from a custom
level used returntomenu(Menu::levellist) when quittomenu() already had
that same returntomenu()).
The menu that exiting from the level editor returns to is now handled in
game.quittomenu() as well, where the map.custommode branch now also
checks for map.custommodeforreal. Unfortunately, it seems like entering
the level editor doesn't properly initialize map.custommode, so entering
the level editor now initializes map.custommode, too.
I've also taken the music.play(6) out of game.quittomenu(), because not
all exit paths immediately play Presenting VVVVVV, so all exit paths
that DO immediately play Presenting VVVVVV now have music.play(6)
special-cased for them, which is fine enough for me.
Here is the list of all exit paths to the menu:
- Exiting through the pause menu (without glitchrunner mode)
- Exiting through the pause menu (with glitchrunner mode)
- Completing a custom level
- Completing a Time Trial
- Dying in No Death Mode
- Completing No Death Mode
- Completing an Intermission replay
- Exiting from the level editor
- Completing the main game
During 2.3 development, there's been a gradual shift to using SDL stdlib
functions instead of libc functions, but there are still some libc
functions (or the same libc function but from the STL) in the code.
Well, this patch replaces all the rest of them in one fell swoop.
SDL's stdlib can replace most of these, but its SDL_min() and SDL_max()
are inadequate - they aren't really functions, they're more like macros
with a nasty penchant for double-evaluation. So I just made my own
VVV_min() and VVV_max() functions and placed them in Maths.h instead,
then replaced all the previous usages of min(), max(), std::min(),
std::max(), SDL_min(), and SDL_max() with VVV_min() and VVV_max().
Additionally, there's no SDL_isxdigit(), so I just implemented my own
VVV_isxdigit().
SDL has SDL_malloc() and SDL_free(), but they have some refcounting
built in to them, so in order to use them with LodePNG, I have to
replace the malloc() and free() that LodePNG uses. Which isn't too hard,
I did it in a new file called ThirdPartyDeps.c, and LodePNG is now
compiled with the LODEPNG_NO_COMPILE_ALLOCATORS definition.
Lastly, I also refactored the awful strcpy() and strcat() usages in
PLATFORM_migrateSaveData() to use SDL_snprintf() instead. I know save
migration is getting axed in 2.4, but it still bothers me to have
something like that in the codebase otherwise.
Without further ado, here is the full list of functions that the
codebase now uses:
- SDL_strlcpy() instead of strcpy()
- SDL_strlcat() instead of strcat()
- SDL_snprintf() instead of sprintf(), strcpy(), or strcat() (see above)
- VVV_min() instead of min(), std::min(), or SDL_min()
- VVV_max() instead of max(), std::max(), or SDL_max()
- VVV_isxdigit() instead of isxdigit()
- SDL_strcmp() instead of strcmp()
- SDL_strcasecmp() instead of strcasecmp() or Win32 strcmpi()
- SDL_strstr() instead of strstr()
- SDL_strlen() instead of strlen()
- SDL_sscanf() instead of sscanf()
- SDL_getenv() instead of getenv()
- SDL_malloc() instead of malloc() (replacing in LodePNG as well)
- SDL_free() instead of free() (replacing in LodePNG as well)
This patch de-duplicates the tool drawing code a bit in the menu that
gets brought up when you press Space in the level editor, as well as
fixes several bugs related to the fact that the original author(s) of
the code decided to copy-paste everything. (It was most likely Terry,
judging by the distinct lack of whitespace between tokens in the code.)
There are two "pages" of tools that get shown when you open the tool
menu, according to your currently-selected tool.
1. On the first page, your currently-selected tool gets a brighter
outline. However, on the second page, the code to draw the outline over
your currently-selected tool is missing. So I've fixed that.
2. On the first page, the glyph indicator next to the tool icon also
gets brighter when you have that tool selected. However, on the
second page, the code that drew the brighter-colored indicator got
ran before the code that drew the normal-colored indicator, so this
was never shown. This is also fixed.
3. The glyph indicator of the gravity line tool didn't get brighter when
you had it selected, due to its special-cased copy-pasted code
drawing its brighter color before drawing its normal color. This has
also been fixed.
4. Lastly, the tool menu no longer draws the brighter-colored glyphs on
top of the normal-colored glyphs. Instead, the menu will simply draw
the brighter-colored glyphs and will not draw the normal-colored
glyphs in the first place. This is because double-drawing text like
this will look bad if the user has a custom font.png that has
translucent pixels, like I do.
All of these bugs have been fixed by paying off the technical debt of
copy-pasting code.
2.3's per-level assets feature also added a hotkey to reload the custom
assets of the level you're currently editing in the editor, so you
wouldn't have to re-load the level yourself. This hotkey is F9, but
however, it hasn't been documented in the hotkey list brought up by
pressing Shift, until now.
This patch cleans up unnecessary exports from header files (there were
only a few), as well as adds the static keyword to all symbols that
aren't exported and are specific to a file. This helps the linker out in
not doing any unnecessary work, speeding it up and avoiding silent
symbol conflicts (otherwise two symbols with the same name (and
type/signature in C++) would quietly resolve as okay by the linker).
There is a certain ordering of which corners you click on to place enemy
and platform boundaries, and script boxes. You must first click on the
top-left corner, then click on the bottom-right corner. The visual box
that is drawn after you've first clicked on the top-left corner clearly
shows this intended way of doing things.
However, it seems like despite the visuals, the game didn't properly
prevent you from clicking on the corners in the wrong way. If you placed
it from top-right to bottom-left, or bottom-left to top-right, then the
game would place the boxes accordingly, and they would have a weird
shape where two of its opposite sides would just be missing. But,
placing them from bottom-right to top-left is prevented accordingly.
The bug comes down to a simple use of "or", instead of the correct
"and". This isn't the first time the wrong conjunction was used in a
conditional... (8260bb2696, #136)
Since the code block that the if-statement guards is the code that will
execute if the corners placed were correct, the if-statement thus should
be written in the positive case and use a more restrictive "and",
instead of the negative case, which would use a more looser "or". There
are less cases that are correct than cases which are incorrect - in this
case, there is only 1 correct way of doing things (top-left to
bottom-right), compared to 3 incorrect ways of doing things (top-right
to bottom-left, bottom-left to top-right, bottom-right to top-left) - so
when thinking of positive cases, you should be using "and".
Or, you can always just test it. This bug has been in the game since
2.0, so it seems like no one just tested that incorrect input actually
didn't work.
So... it looks like being able to switch through tilesets backwards has
been in 2.3 for a while, guess no one just uses 2.3 or the level editor
that much. It seems like it's always been broken, too.
If you were on the Space Station tileset (tileset 0), pressing Shift+F1
would keep you on the Space Station tileset instead of switching to the
Ship (tileset 4).
It looks like the problem here was mixing size_t and int together - so
the modulus operation promoted the left-hand side to size_t, which is
unsigned, so the -1 turned into SIZE_MAX, which is 18446744073709551615
on my system. You'll note that that ends in a 5, so the number is
divisible by 5, meaning taking it modulo 5 leads to 0. So the tileset
would be kept at 0.
At least unsigned integer underflow/overflow is properly defined, so
there's no UB here. Just careless type mixing going on.
The solution is to make the modulus an int instead of a size_t. This
introduces an implicit conversion, but I don't care because my compiler
doesn't warn about it, and implicit conversion warnings ought to be
disabled on MSVC anyway.
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.
As part of fixing #464, I'll need to move these pieces of code around
easily. In #220 I just kind of shoved them awkwardly in whatever
fixed function would be last called in the gamestate loop, which I
shouldn't have done as I've now had to make formal fixed-render
functions anyway. Because these fixed functions need to be called
directly before a render function, and I'm fixing the order to put
render functions in their proper place, so I need to be able to move
these around easily, and making them function calls instead of inlined
makes them easier to manipulate.
There were some duplicate Screen configuration variables that were on
Game, when there didn't need to be.
- game.fullScreenEffect_badSignal is a duplicate of
graphics.screenbuffer->badSignalEffect
- game.fullscreen is a duplicate of !graphics.screenbuffer->isWindowed
- game.stretchMode is a duplicate of graphics.screenbuffer->stretchMode
- game.useLinearFilter is a duplicate of
graphics.screenbuffer->isFiltered
These duplicate variables have been removed now.
I put indentation when handling the ScreenSettings struct in main() so
the local doesn't live for the entirety of main() (which is the entirety
of the program).
What's the difference between a slash sign and a percent sign? Well, a
percent sign is just a slash sign with two extra oranges in between, but
those two oranges make a huuuuge difference...
In C++, when you have two variables in different scopes with the same
name, the inner scope wins. Except you have to be really careful because
sometimes they're not (#507). So it's better to just always have unique
variable names and make sure to never clash a name with a variable in an
outer scope - after all, the C++ compiler and standard might be fine
with it, but that doesn't mean humans can't make mistakes reading or
writing it.
Usually I just renamed the inner variables, but for tx/ty in editor.cpp,
I just got rid of the ridiculous overcomplicated modulo calculations and
replaced them with actual simple modulo calculations, because the
existing ones were just ridiculous. Actually, somebody ought to find
every instance of the overcomplicated modulos and replace them with the
actual good ones, because it's really stupid, quite frankly...
My previous custom level forwards compatibility would only work if you
saved to the same filename as you read from. But what if you saved to a
new filename? Well, your extra XML is lost.
Not to worry, I've introduced a variable that remembers the filepath of
the currently-loaded level (the existing `filename` attribute is kind of
weird and not really suited for this purpose, so). I tried to make it a
simple `const char*`, but it turns out that's bad when you take the
`c_str()` of an `std::string` that then gets destroyed, so it's best to
use `std::string` in an `std::string` world.
So now when you save a level, it'll attempt to open the original file,
and if that doesn't exist then your extra XML gets lost anyway, but I
shouldn't be expected to keep your XML if you delete the original file.
Custom level files now have forwards compatibility - except that some
XML objects will simply discard contents and attributes they don't see
fit. For instance, edentities and level properties will not preserve
newer attributes or contents.
This is because preserving them would require having to track the XML
object as part of the edentity internally, because the edentity might
change places or even be deleted throughout the course of editing
someone's level.
I opted to not add support for preserving objects like these, because
frankly, the put-everything-in-one-file level format was and still is a
terrible idea, and we should probably switch to a new format in the
future that isn't single-file. So when that happens, there won't be a
need to preserve XML attributes on edentities.
With the previous commit in place, we can now simply move some usages of
the previous towerbg to use a separate object instead. That way, we
don't have to mess with a monolithic state, or some better way to phrase
what I just said, and we instead have two separate objects that can
coexist side-by-side.
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.
I got this warning during compilation because there were two nested for
loops both defining i. Better to have different names to make sure some
compilers won't overwrite the outer variable with the inner one.
It seems like the start point of a custom level and all checkpoints in
the game end up putting your spawn point one pixel away from the surface
it touches, which seems like an oversight. I'm going to enforce some
consistency here and make it so that all spawn points, whenever you
start from a start point or a checkpoint, will always be correctly
positioned flush with the surface they're standing on, and not one pixel
more or less than that.
An exotic checkpoint is a checkpoint with a sprite that is neither the
flipped checkpoint nor unflipped checkpoint. More specifically, it's a
checkpoint whose edentity p1 attribute is something other than 0 or 1.
Normally, whenever you touch an exotic checkpoint in-game, your
savepoint's y-position and gravitycontrol don't get touched. However, in
the editor, spawning from an exotic checkpoint means that your
gravitycontrol gets set to a value that is neither 0 nor 1. In this
invalid gravitycontrol state, Viridian is treated like they're flipped,
but they cannot unflip.
This is an inconsistency between the editor and in-game, so I'm fixing
it. Now, spawning from an exotic checkpoint in the editor will just set
your gravitycontrol to 0, i.e. unflipped.
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.
This prevents users from being confused whenever they type a pipe in the
script editor, then save the level and load it again and see their
script lines unexpectedly splitting in two. Now if you attempt to type a
pipe, it simply won't happen at all.
Fixes#379.
I have no idea why neither conveyors and moving and disappearing
platforms rendered in the editor or in-game use
Graphics::drawentcolours(), but this needs to be bounds-checked just as
I did for the in-game rendering function.
When this is done, there is potential for a mistake to occur when
writing out the bounds check, which is eliminated when using the macro
instead. Luckily, this doesn't seem to have happened, but what's even
worse is I hardcoded 400 instead of using SDL_arraysize(ed.level), so if
the size of ed.level the bounds checks would all be wrong, which
wouldn't be good. But that's fixed now, too.
Since there's an INBOUNDS_ARR() macro, it's much better to specify the
macro for the vector is a macro for the vector, to avoid confusion.
All usages of this macro have been renamed accordingly.
