I've made a new function, Graphics::do_print(), that does the actual
text printing itself. All the interfaces of the other functions have
been left alone, but now just call do_print() instead.
I also removed PrintOffAlpha() and just calculated the center x-position
in bprintalpha() itself (like bigbprint() does) to make it easier to
de-duplicate code.
I'm honestly not too sure why drawcustompixeltextbox ever existed? All
it seemed to do was draw even more horizontal/vertical tiles to finish
any gaps in the tiling... which was all completely unnecessary and
wasteful, because even the previous drawpixeltextbox implementation
covered all gaps in all custom level map sizes that I tried.
Anyway, that at least gets rid of one copy-pasted function.
This will wrap text on-the-fly, since I will be introducing text that
needs to be wrapped whose length we can't know in advance. (Or we can,
but, that'd be stupid.)
I took the algorithm from Dav999's localization branch, but it's not
like it's a complicated algorithm in the first place. Plus I think it
actually handles words that get too long to fit on a single line better
than his localization branch. The only difference is that I removed all
the STL, and made it more memory efficient (unlike his localization
branch, it does not copy the entire string to make a version with
newline separator characters).
This is a simple change - we draw minimap.png, instead of the generated
custom map, if it is a per-level mounted custom asset.
Custom levels have already been able to utilize minimap.png, but it was
limited - they could do gamemode(teleporter) in a script, and that would
show their customized minimap.png, but it's not like the player could
look at it during gameplay.
I would have done this earlier if I had figured out how to check if a
specific asset was mounted or not.
The config option has been removed. I'm going to implement something
that automatically shows and hides the mouse cursor whenever
appropriate, which is better than a config option.
It's just like bigprint() except it duplicates some of the calculations
because I didn't want to make a bigprintoff() function which would
duplicate even more code. I'm beginning to think these text printing
functions are completely horrible to work with...
While I've decoupled fademode from gamemode starting, being faded out on
the title screen results in a black screen and you being unable to make
any input. So we'll need to store the current fademode in a temporary
variable when going to in-game options, then put it back when we return
to the pause menu. Yes, you can turn on glitchrunner mode during the
in-game options, and then immediately return to the pause menu to
instantly go back to the title screen; this is intended.
Due to frame ordering, putting the fademode back needs to be deferred to
the end of the frame to prevent a 1-frame flicker.
It's actually sufficient enough to do this temporary fademode storage to
fix the whole thing, but I also decided to decouple fademode and
gamemode starting just to be sure.
In 2.2, at render time, the game rendered screenshakes and flashes if
their timers were above 0, and then decremented them afterwards. The
game would also update the analogue filter right before rendering it,
too.
In 2.3, this was changed so the flash and screenshake timers were
unified, and also done at the end of the frame - right before rendering
happened. This resulted in 1-frame flashes and screenshakes not
rendering at all. The other changes in this patchset don't fix this
either. The analogue filter was also in the wrong order, but that is
less of an issue than flashes and screenshakes.
So, what I've done is made the flash and screenshake timers update right
before the loop switches over to rendering, and only decrements them
when we switch back to fixed functions (after rendering). The analogue
filter is also updated right before rendering as well. This restores
1-frame flashes and screenshakes, as well as restores the correct order
of analogue filter updates.
createtextboxreal() is the same as createtextbox(), but with a flipme
parameter added to create text boxes that have their flipme attribute
set to true. createtextbox() just calls createtextboxreal() with flipme
set to false, and createtextboxflipme() just calls createtextboxreal()
with flipme set to true; this is because I do not want to use C++
function overloading.
These default arguments are never used anywhere. And if they were used
anywhere, it'd be better to explicitly say 255,255,255 than make readers
have to look at the header file to see what these default to. Also, this
creates four different overloads of createtextbox(), instead of only
two - but we ought to not be using function overloading anyway.
Like cutscene bars, I've added Graphics::setfade(), to ensure that no
deltaframe rendering glitches happen due to oldfadeamount not being
updated properly.
And indeed, this fixes a deltaframe rendering glitch that happens if you
return to the editor from playtesting on a faded-out screen, then fade
out again (by either re-entering playtesting and then cause a fadeout to
happen again, or by quitting from the editor afterwards). The same
glitch also happens outside of in-editor playtesting if you exit to the
menu while the screen is faded out.
To do this, I've added Graphics::setbars(), to make sure
oldcutscenebarspos always gets assigned when cutscenebarspos is. This
fixes potential deltaframe rendering issues if these two mismatch.
So, 2.3 added recoloring one-way tiles to no longer make them be always
yellow. However, custom levels that retexture the one-way tiles might
not want them to be recolored. So, if there are ANY custom assets
mounted, then the one-ways will not be recolored. However, if the XML
has a <onewaycol_override>1</onewaycol_override> tag, then the one-way
will be recolored again anyways.
When I added one-way recoloring, I didn't intend for any custom asset to
disable the recoloring; I only did it because I couldn't find a way to
check if a specific file was customized by the custom level or not.
However, I have figured out how to do so, and so now tiles.png one-way
recolors will only be disabled if there's a custom tiles.png, and
tiles2.png one-way recolors will only be disabled if there's a custom
tiles2.png.
In order to make sure we're not calling PhysFS functions on every single
deltaframe, I've added caching variables, tiles1_mounted and
tiles2_mounted, to Graphics; these get assigned every time
reloadresources() is called.
Now you only have to call one function (and pass it a tile number) to
figure out if you should recolor a one-way tile or not, and you don't
have to copy-paste.
It's only used in FileSystemUtils and never anywhere else, especially
not Graphics. Why is this on Graphics again?
It's now a static variable inside FileSystemUtils. It has also been
renamed to assetDir for consistency with saveDir and levelDir. Also,
it's a C string now, and is no longer an STL string.
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.
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.
It doesn't feel quite write leaving all the buffer creation code in
main(), even though it's perfectly okay to do so and it doesn't result
in any memory mismanagement that Valgrind can report; so I'm factoring
all of it out to a separate function, Graphics::create_buffers().
As a bonus, we no longer have to keep qualifying with `graphics.` in the
buffer creation code, which is nice.
These destroy all the buffers that are created on the Graphics class.
Since these buffers can't be created at the same time as the rest of
Graphics is (due to the fact that they require knowing the pixel format
of the game screen), they can't be destroyed at the same as the rest of
Graphics is, either.
Instead of using the same tower buffer that gets used for towers, use a
separate buffer instead so there's no risk of stepping on the tower
buffer's toes at the wrong point in time.
This commit combined with the previous one fixes#369.
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.
For some reason, this `tl` is a `point`? But the only other time the
name `tl` is used elsewhere in the code is a float on a `textboxclass`.
Regardless, this is unused.
In order to fix the weird title screen pixels at the top on deltaframes,
we'll need to have a bit more space at the top. Also to the left, in
case we need a background to scroll from the left in the future.
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.
When I added the over-30-FPS mode, I kept running into this problem
where the special images of text boxes would render during the
deltaframes of fade-in/fade-out animations, even though they shouldn't
be. So I simply added a flag to the text box that enables drawing these
special images.
However, this doesn't solve the problem fully, and there's still a small
chance that a special-image text box could draw another special image
during its deltaframes. It's really rare and you have to have your
deltaframe luck juuuuuust right (or you could use libTAS, probably), but
it helps to be in 40% slowmode and have a high refresh rate (which, if
it isn't a multiple of 30, you should disable VSync, too, in order to
not have a low framerate).
So instead, special images will only be drawn if the text box has fully
faded in completely. That solves the issue completely.
If you have the translucent room name option enabled, you'd always be
seeing the spikes at the bottom of the screen hidden behind the room
name. This patch makes it so that the spikes get carefully cropped so
they only appear above the room name when the player gets close to the
bottom of the screen.
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.
Graphics::drawmenu() no longer has copy-pasted code for each individual
case. Instead, the individual cases have their own adding on to common
code, which is far easier to maintain.
Also, the only difference Graphics::drawlevelmenu() does is in some
y-positioning stuff. There's no reason to make it a whole separate
function and duplicate everything AGAIN. So it's been consolidated into
Graphics::drawmenu() as well, and I've added a boolean to draw a menu
this way if it's the level menu.
These unused vars are:
- Graphics::bfontmask_rect
- Graphics::backgrounds
- Graphics::bfontmask
- GraphicsResources::im_bfontmask
While it seems that Graphics::backgrounds was indexed in
Graphics::drawbackground(), in reality there was never anything in that
vector and thus actually using it would cause a segfault.
The problem we're running into is entirely contained in the Screen - we need to
either decouple graphics context init from Screen::init or we need to take out
the screenbuffer interaction from loadstats (which I'm more in favor of since we
can just pull the config values and pass them to Screen::init later).
The game for some reason had this thing where it would not draw the
diagonal background tiles if you had animated backgrounds turned off.
Which is weird, because spikes with that background are still drawn as
spikes with that background. And also, it doesn't do this for any of the
tower hallway rooms, which is inconsistent.
Better to simplify the logic in Render.cpp anyways by removing
graphics.drawtower_nobackground() and making it really clear what
exactly we'll do if backgrounds are turned off. ("Aren't we already not
drawing the background? What's this _nobackground() function for?")
All menus had a hardcoded X position (offset to an arbitrary starting
point of 110) and a hardcoded horizontal spacing for the "staircasing"
(mostly 30 pixels, but for some specific menus hardcoded to 15, 20 or
something else). Not all menus were centered, and seem to have been
manually made narrower (with lower horizontal spacing) whenever text
ran offscreen during development.
This system may already be hard to work with in an English-only menu
system, since you may need to adjust horizontal spacing or positioning
when adding an option. The main reason I made this change is that it's
even less optimal when menu options have to be translated, since
maximum string lengths are hard to determine, and it's easy to have
menu options running offscreen, especially when not all menus are
checked for all languages and when options could be added in the middle
of a menu after translations of that menu are already checked.
Now, menus are automatically centered based on their options, and they
are automatically made narrower if they won't fit with the default
horizontal spacing of 30 pixels (with some padding). The game.menuxoff
variable for the menu X position is now also offset to 0 instead of 110
The _default_ horizontal spacing can be changed on a per-menu basis,
and most menus (not all) which already had a narrower spacing set,
retain that as a maximum spacing, simply because they looked odd with
30 pixels of spacing (especially the main menu). They will be made even
narrower automatically if needed. In the most extreme case, the spacing
can go down to 0 and options will be displayed right below each other.
This isn't in the usual style of the game, but at least we did the best
we could to prevent options running offscreen.
The only exception to automatic menu centering and narrowing is the
list of player levels, because it's a special case and existing
behavior would be better than automatic centering there.
Similar to Graphics::map_tab(), this ensures that I don't have to
copy-paste printing the map options for every single game.menupage case
I want, and in this case that's a good thing because there'll be 4
game.menupage cases I'll be using.
This function is useful to de-duplicate all the map page names at the
bottom, which are MAP, CREW/SHIP/GRAV, STATS, and SAVE. If selected, it
will surround the text in square brackets and automatically handle the
positioning.
Shamelessly copy-pasted from Dav999's localization branch.
