Clean up and prevent unnecessary qualifiers to self 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.

Separate includes into sections and alphabetize them 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).

#include "BinaryBlob.h"
Factor fade amount calculation to separate function This makes it so to reuse this code, we don't have to copy-paste it. Additionally, I added a check for the milliseconds being 0, to avoid a division by zero. Logically and mathematically, if the fade amount is 0 milliseconds, then that means the fade should happen instantly - however, dividing by zero is undefined (both in math and in C/C++), so this check needs to be added.

#include "Map.h"
Remove unnecessary includes from header files 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.

Explicitly declare void for all void parameter functions (#628) 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.

static void songend(void);
Fix resumemusic/musicfadein not working It seems like they were unfinished. This commit makes them properly work. When a track is stopped with stopmusic() or musicfadeout(), resumemusic() will resume from where the track stopped. musicfadein() does the same but does it with a gradual fade instead of suddenly playing it at full volume. I changed several interfaces around for this. First, setting currentsong to -1 when music is stopped is handled in the hook callback that gets called by SDL_mixer whenever the music stops. Otherwise, it'd be problematic if currentsong was set to -1 when the song starts fading out instead of when the song actually ends. Also, music.play() has a few optional arguments now, to reduce the copying-and-pasting of music code. Lastly, we have to roll our own tracker of music length by using SDL_GetPerformanceCounter(), because there's no way to get the music position if a song fades out. (We could implicitly keep the music position if we abruptly stopped the song using Mix_PauseMusic(), and resume it using Mix_ResumeMusic(), but ignoring the fact that those two functions are also used on the unfocus-pause (which, as it turns out, is basically a non-issue because the unfocus-pause can use some other functions), there's no equivalent for fading out, i.e. there's no "fade out and pause when it fully fades out" function in SDL_mixer.) And then we have to account for the unfocus-pause in our manual tracker. Other than that, these commands are now fully functional.

musicclass::musicclass(void)
Don't reset entire musicclass when mounting and unmounting assets musicclass::init() re-initializes every attribute of musicclass unnecessarily, when initialization should be put in a constructor instead. This is bad, because music.init() gets called whenever we enter and exit a custom level that has assets. Otherwise, this would result in a bug where music.usingmmmmmm would be reset, causing you to revert to PPPPPP on the title screen whenever you enter a level with MMMMMM selected and exit it. This also causes a confusing desync between game.usingmmmmmm and music.usingmmmmmm since the values of the two variables are now different (these duplicate variables should probably be removed, too, and a lot of other duplicate variables like these exist, too, which are a real headache). Which means despite MMMMMM playing on the title screen, exiting the game and re-launching it will play PPPPPP instead. What's even more is that going to game options and switching to PPPPPP will play PPPPPP, but afterwards launching and re-entering will play MMMMMM. Again, having duplicate variables is very bad, and should probably be fixed, but that's a separate patch.

Separate musicReadBlob into mmmmmm_blob and pppppp_blob musicReadBlob was used for both MMMMMM and PPPPPP soundtracks. This causes a memory leak if you have mmmmmm.vvv installed, because the pointers holding each allocated block of MMMMMM would be lost when PPPPPP got loaded. Valgrind complains about this memory leak. This is in contrast to 2.2 and previous behavior, where musicReadBlob was only a temporary object instead of being held in musicclass. However, this wasn't really a memory leak (moreso something that just didn't get cleaned up when closing the game), but it did get turned into a leak when per-level assets mounting and unmounting got introduced in 2.3 (loading a level with custom assets after starting the game with an mmmmmm.vvv, or exiting out of a level that had an mmmmmm.vvv, would cause the game to leak memory). Leo recognized this, and moved musicReadBlob onto musicclass in a separate 2.3 PR, but either he didn't think about what was happening here too closely, or he didn't use Valgrind, because he forgot about the memory leak caused by re-using the same binaryBlob for PPPPPP and MMMMMM.

Check index of tracks in musicclass::init() It's possible that musicReadBlob.getIndex() could return the sentinel value of -1 in case the header with that name is invalid, in which case we should simply not do anything. Otherwise it'll lead to segfaults. I opted to do the full bounds check just to be safe, too. For further safety, I hardcoded the max number of headers, 128, less, so 128 is copy-pasted less and in the future if it needs to be changed it'll only have to be changed in one place.

Refactor extra binary blob tracks to not use STL data marshalling Just like I refactored text splitting to no longer use std::vectors, std::strings, or temporary heap allocations, decreasing memory usage and improving performance; there's no reason to use a temporary heap-allocated std::vector to grab all extra binary blob indices, when instead the iteration can just be more immediate. Instead, what I've done is replaced binaryBlob::getExtra() with binaryBlob::nextExtra(), which takes in a pointer to an index variable, and will increment the index variable until it reaches an extra track. After the caller processes the extra track, it is the caller's responsibility to increment the variable again before passing it back to getExtra(). This avoids all heap allocations and brings down the memory usage of processing extra tracks.

Fix resumemusic/musicfadein not working It seems like they were unfinished. This commit makes them properly work. When a track is stopped with stopmusic() or musicfadeout(), resumemusic() will resume from where the track stopped. musicfadein() does the same but does it with a gradual fade instead of suddenly playing it at full volume. I changed several interfaces around for this. First, setting currentsong to -1 when music is stopped is handled in the hook callback that gets called by SDL_mixer whenever the music stops. Otherwise, it'd be problematic if currentsong was set to -1 when the song starts fading out instead of when the song actually ends. Also, music.play() has a few optional arguments now, to reduce the copying-and-pasting of music code. Lastly, we have to roll our own tracker of music length by using SDL_GetPerformanceCounter(), because there's no way to get the music position if a song fades out. (We could implicitly keep the music position if we abruptly stopped the song using Mix_PauseMusic(), and resume it using Mix_ResumeMusic(), but ignoring the fact that those two functions are also used on the unfocus-pause (which, as it turns out, is basically a non-issue because the unfocus-pause can use some other functions), there's no equivalent for fading out, i.e. there's no "fade out and pause when it fully fades out" function in SDL_mixer.) And then we have to account for the unfocus-pause in our manual tracker. Other than that, these commands are now fully functional.

Explicitly declare void for all void parameter functions (#628) 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.

Clean up and prevent unnecessary qualifiers to self 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.

music.songEnd = SDL_GetPerformanceCounter();
Move resumesong assignment to songend() This fixes a bug where the resumemusic() script command would always play MMMMMM track 15 (or, if you're using PPPPPP, just not work). This is because musicclass::haltdasmusik() assigns resumesong AFTER calling Mix_HaltMusic(), but the songend() callback fires before the resumesong assignment, meaning resumesong gets set to -1 instead of whatever currentsong was previously. To fix this, just move the assignment into the callback itself (I don't know why this wasn't done before). I could have moved it to before the Mix_HaltMusic() call, but moving it into the callback itself fixes it for all cases of the music stopping (such as when the music fades out).

Separate musicReadBlob into mmmmmm_blob and pppppp_blob musicReadBlob was used for both MMMMMM and PPPPPP soundtracks. This causes a memory leak if you have mmmmmm.vvv installed, because the pointers holding each allocated block of MMMMMM would be lost when PPPPPP got loaded. Valgrind complains about this memory leak. This is in contrast to 2.2 and previous behavior, where musicReadBlob was only a temporary object instead of being held in musicclass. However, this wasn't really a memory leak (moreso something that just didn't get cleaned up when closing the game), but it did get turned into a leak when per-level assets mounting and unmounting got introduced in 2.3 (loading a level with custom assets after starting the game with an mmmmmm.vvv, or exiting out of a level that had an mmmmmm.vvv, would cause the game to leak memory). Leo recognized this, and moved musicReadBlob onto musicclass in a separate 2.3 PR, but either he didn't think about what was happening here too closely, or he didn't use Valgrind, because he forgot about the memory leak caused by re-using the same binaryBlob for PPPPPP and MMMMMM. So instead, just use two different binaryBlob objects for MMMMMM and PPPPPP. That way, no memory leaks happen.

Clean up music handling to one place Previously, setting the actual volume of the music was all over the place. Which isn't bad, but when I added being able to press N to mute the music specifically, I should've made it so that there would be a volume variable somewhere that the game looks at if the music is unmuted, and otherwise sets the actual volume to 0 if the game is muted. This resulted in things like #400 and #505 and having to add a bunch of special-cased checks like game.musicmuted and game.completestop. But instead of adding a bunch of special-case code, just make it so there's a central place where Mix_VolumeMusic() actually gets called, and if some piece of code wants to set the music volume, they can set music.musicVolume. But the music handling logic in main.cpp gets the final say on whether to listen to music.musicVolume, or to mute the game entirely. This is how the music handling code should have been from the start (when pressing N to mute the music was added). Fixes #505.

Fix resumemusic/musicfadein not working It seems like they were unfinished. This commit makes them properly work. When a track is stopped with stopmusic() or musicfadeout(), resumemusic() will resume from where the track stopped. musicfadein() does the same but does it with a gradual fade instead of suddenly playing it at full volume. I changed several interfaces around for this. First, setting currentsong to -1 when music is stopped is handled in the hook callback that gets called by SDL_mixer whenever the music stops. Otherwise, it'd be problematic if currentsong was set to -1 when the song starts fading out instead of when the song actually ends. Also, music.play() has a few optional arguments now, to reduce the copying-and-pasting of music code. Lastly, we have to roll our own tracker of music length by using SDL_GetPerformanceCounter(), because there's no way to get the music position if a song fades out. (We could implicitly keep the music position if we abruptly stopped the song using Mix_PauseMusic(), and resume it using Mix_ResumeMusic(), but ignoring the fact that those two functions are also used on the unfocus-pause (which, as it turns out, is basically a non-issue because the unfocus-pause can use some other functions), there's no equivalent for fading out, i.e. there's no "fade out and pause when it fully fades out" function in SDL_mixer.) And then we have to account for the unfocus-pause in our manual tracker. Other than that, these commands are now fully functional.

Explicitly declare void for all void parameter functions (#628) 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.

Factor fade amount calculation to separate function This makes it so to reuse this code, we don't have to copy-paste it. Additionally, I added a check for the milliseconds being 0, to avoid a division by zero. Logically and mathematically, if the fade amount is 0 milliseconds, then that means the fade should happen instantly - however, dividing by zero is undefined (both in math and in C/C++), so this check needs to be added.

Clean up don't-quick-fade signaling First, the variable has been inverted, because it's bad practice to have booleans with negative names. Secondly, instead of magically setting a signaling variable when calling fadeout(), fadeout() now has a parameter to set the quick_fade attribute, which is much cleaner than doing the magical assignment that could potentially look unrelated.

Don't manually write out INBOUNDS_VEC() checks This is because if they are manually written out, they are more likely to contain mistakes. In fact, after further review, there are several functions with incorrect manually-written bounds checks: * entityclass::entitycollide() * entityclass::removeentity() * entityclass::removeblock() * entityclass::copylinecross() * entityclass::revertlinecross() All of those functions forgot to do 'greater than or equal to' instead of 'greater than' when comparing against the size of the vector. So they were erroneous. But they are now fixed.

if (!INBOUNDS_VEC(t, soundTracks))
Add bounds checks to script commands that didn't have them Continuing from #280, another potential source of out-of-bounds indexing (and thus, Undefined Behavior badness) comes from script commands. A majority of them don't do any input validation at all, which means the potential for out-of-bounds indexing and segfaulting in custom levels. So it's always good to add bounds checks to them. Interesting note, the only existing command that has bounds checks is the flag() command. That means you can't turn out-of-bounds flags on or off. But there's no bounds checks for ifflag(), or customifflag(), which means you CAN index out-of-bounds with those commands! That's a bit bad to do, so. Also, I decided to add the bounds checks for playef() at the musicclass::playef() level, instead of just the level of the playef() command. I don't know of any other cases outside of the command where musicclass::playef() will index out of bounds, but musicclass is the one containing the indexed vector anyway, I wanted to cover more cases, and it's better to be safe than sorry.
