The previous way manually concatenated the first 7 characters of the
string together (and had an std::min() calculation). The new way instead
does std::string::substr(), which is much more snappy.
The actual unindent is done in a separate commit to minimize noise,
because diffs are terrible at clearly conveying unindents (it should put
all the minus lines together and all the plus lines together, too).
The entirety of the rest of scriptclass::loadcustom() is encased in a
block that first checks if the script with the name even exists. Instead
of indenting the rest of the function, just invert the check and reduce
indentation level.
This commit refactors custom level scripts to no longer be stored in one
giant vector containing not only every single script name, but every
single script's contents as well. More specifically,
scriptclass::customscript has been converted to an std::vector<Script>
scriptclass::customscripts (note the extra S), and a Script is just a
struct with an std::string name and std::vector<std::string> contents.
This is an improvement in both performance and maintainability. The game
no longer has to look through script contents in case they're actually
script names, and then manually extract the script contents from there.
Instead, all it has to do is look for script names only. And the
contents are provided for free. This results in a performance gain.
Also, the old system resulted in lots of boilerplate everywhere anytime
scripts had to be handled or parsed. Now, the boilerplate is only done
when saving or loading a custom level. This makes code quality much,
much better.
To be sure I didn't actually change anything, I tested by first saving
Dimension Open in current 2.3 (because current 2.3 gets rid of the
awful edentity whitespace), and then resaved it on this patch. There is
absolutely no difference between the current-2.3-resave and
this-patch-resave.
This enforces the C++03 standard for people making pull requests who may
not realize their fancy features are too new and shouldn't be used
(cough, cough, @leo60228).
I did some internet searching and this is what I got from this page:
https://crascit.com/2015/03/28/enabling-cxx11-in-cmake/
This resulted in two bugs:
1. Custom assets would not be unmounted when quitting to the menu.
2. Custom assets would be unmounted when playtesting a level.
The solution is to unmount assets in Game::quittomenu() instead.
Main game would retain custom level assets, now fixed. Also, custom fonts load properly. Finally, levels can be stored as a zip and placed in the levels folder, with the .vvvvvv file at the root of the zip and custom asset folders (graphics, sounds etc) also at the root.
Previously, the editor would always say it saved or loaded a level,
even if it was not successful. For example, because a file to load does
not exist, a file to save has illegal characters in its name or the
name is too long to be stored. Now failure is reported. Also, when
quitting the editor and saving before quitting is unsuccessful, the
editor will abort quitting.
I think it's a bit silly to always include the Steam and GOG APIs
whenever we build VVVVVV, since the only time they'll ever be used is in
a live build and not a dev build.
So now Steam and GOG are disabled by default. If you want them, you'll
need to add -DSTEAM=ON or -DGOG=ON respectively at CMake time. They're
also both automatically enabled for release builds.
This commit adds bounds checks to those commands in case say()/reply()
asks for more lines than there are left in the all-script-lines buffer
(not just the current script, so in order for it to segfault your script
has to be last in the all-script-lines vector), and in case text() asks
for more lines than there are in the rest of the rest of the parsed
internal script.
For some reason, scriptclass::loadcustom() sometimes refers to
`customscript` as `script.customscript` instead of `customscript`. The
`script.` is unnecessary.
Although it's not an issue, this should minimize the stack footprint of
calling scriptclass::load(), especially if it goes down to calling
scriptclass::loadcustom() or scriptclass::loadother().
Otherwise, it would end up indexing a vector out-of-bounds, which is UB
and causes a segfault, too. This is used in some constructs like
say(-1)
<internal command>
where the text contents don't matter, only that a text box shows up.
The `speak` command is the exact same as the `speak_active` command,
except without one line of code. So instead of copy-pasting the entire
thing, it's better to just combine them into the same chunk of code.
Instead each line is now held in a const char* array, like it should be.
This results in less work for the compiler, especially with
optimization, since every time the compiler encounters a constant
argument in a function, it has to go off and locate a place to put it.
But if we're upfront and say, hey, here's all the strings we ever need
conveniently packaged into one place, it'll be much more cooperative.
I have the feeling that none of the devs understood what extern did, and
they kind of just sprinkled it everywhere until things started working.
But like all other classes, it should just be one line in the class's
respective header file, and shouldn't be so messy.
When the game loads a room in a custom level, previously it would load
the tilemap of that room into ed.swapmap, and then mapclass::loadlevel()
would manually go through each element in ed.swapmap to set each tile in
`contents`. Why do that, when you can just return the vector from
editorclass::loadlevel() and set it directly? ed.swapmap is really
unnecessary.
It's a bit bad for the compiler if you have lots of function calls with
hardcoded strings in them, because every time the compiler encounters
one, it has to go out of its way to find a dedicated storage location
for the string, which is really inefficient. And it does this
inefficient thing every single time.
There's not much of an impact compiling these lists, but I at least want
to encourage this sort of code style, instead of the push_back(string)
style, in case we ever need a hardcoded array of things later.
Resetting game.activeactivity fixes triggering Undefined Behavior if you
quit to the menu while standing inside an activity zone, and then
re-entered the game. Resetting game.act_fade also fixes the activity
zone prompt fadeout that happens once the above segfault is fixed.
Don't worry, other activity-zone like variables such as teleporter
prompts and trophy text are already covered. obj.trophytext is reset in
scriptclass::hardreset(), too, and game.readytotele is reset every time
mapclass::gotoroom() is called, and mapclass::gotoroom() is called every
time a gamemode is started.
For some reason, the only way to get a cyan crewmate is by cycling
through an already-existing crewmate by keeping left-clicking on it.
This is because when you cycle through crewmate colors, the allowed
colors are 0-5, but when you place down a crewmate, it picks a random
color from 1-5, which seems to be a bit consistent.
So placing and cycling a crewmate now use the same color ranges.
Blackout mode doesn't work properly, because the game doesn't actually
black out the screen, it merely stops drawing things. Oh and only some
things at that, some other things are still drawn. This results in a
freeze-frame effect, which is apparently fixed in the Switch version.
Custom levels utilize this freeze-frame effect, so it's a bit annoying
that the "Game paused" screen draws on top of it and makes it so that
the freeze-frame freezes on "Game paused" until blackout is turned off.
So I'm making it so that "Game paused" doesn't get drawn in blackout
mode. However it will still do graphics.render() because otherwise it'll
just result in a black screen.
This fixes being able to trigger Undefined Behavior by pressing R when
not in-bounds in the Outside Dimension VVVVVV map, usually when you're
falling upwards towards Game Complete.
I also put bounds checks on normal roomdeaths for good measure. You'll
never know when you need it.
Instead of using somewhat-obtuse for-loops to initialize or reset these
vectors, it takes up less lines of code and is clearer if we use
std::vector::resize() and std::vector::clear() instead.
