Again, it used this severely overcomplicated expression for god knows
what reason. I've replaced it with a simpler one. Also it's const just
to indicate intent.
Previously it copy-pasted this god-awful overcomplicated expression
(possibly for cursed ActionScript legacy reasons?) everywhere, instead
of putting it in a variable, or even just using a simpler one like the
one I replaced it with.
Now the obj.createentity() and obj.createblock() calls are much nicer.
Instead of using gamestates, just directly use the 'script' attribute of
a script box if it is non-empty.
This is accomplished by having to return the index of the block that the
player collides with, so callers can inspect the 'script' attribute of
the block themselves, and do their logic accordingly.
game.customscript is an unnecessary middleman, but it will be kept
around for compatibility reasons. However, it's still possible to crash
the game, so I'm adding this bounds check.
To avoid going through gamestates, we'll need to carry the name of the
script on the script box itself. And to do that, we'll need to set the
'script' attribute of script boxes when translating edentities into real
entities in custom levels.
I ran the game through cppcheck and it spat out a bunch of member
attributes that weren't being initialized. So I initialized them.
In the previous version of this commit, I added constructors to
GraphicsResources, otherlevelclass, labclass, warpclass, and finalclass,
but flibit says this changes the code flow enough that it's risky to
merge before 2.4, so I got rid of those constructors, too.
map.contents always has 1200 tiles in it, there's no reason it should be
a vector.
This is a big commit because it requires changing all the level classes
to return a pointer to an array instead of returning a vector. Which
took a while for me to figure out, but eventually I did it. I tested to
make sure and there's no problems.
They're always fixed-size anyways, there's no need for them to be
vectors.
Also used the new INBOUNDS_ARR() macro for the map.explored bounds
checks in Script.cpp, and made map.explored a proper bool array instead
of an int array.
This patch is very kludge-y, but at least it fixes a semi-noticeable
visual issue in custom levels that use internal scripts to spawn
entities when loading a room.
Basically, the problem here is that when the game checks for script
boxes and sets newscript, newscript has already been processed for that
frame, and when the game does load a script, script.run() has already
been processed for that frame.
That issue can be fixed, but it turns out that due to my over-30-FPS
game loop changes, there's now ANOTHER visible frame of delay between
room load and entity creation, because the render function gets called
in between the script being loaded at the end of gamelogic() and the
script actually getting run.
So... I have to temporary move script.run() to the end of gamelogic()
(in map.twoframedelayfix()), and make sure it doesn't get run next
frame, because double-evaluations are bad. To do that, I have to
introduce the kludge variable script.dontrunnextframe, which does
exactly as it says.
And with all that work, the two-frame (now three-frame) delay is fixed.
It's annoying for casuals to have to close the game if they manage to
get themselves to turn into VVVVVV-Man, but it's amusing enough to
glitchrunners that they mess about with VVVVVV-Man in the main game,
clipping through walls everywhere (well, they call it Big Viridian, but
still).
Ironically enough, resetting more variables in script.hardreset() makes
the glitchy fadeout system even more glitchy. Resetting map.towermode,
for example, makes it so that if you're in towers when you quit to the
menu, script.hardreset() makes it so that the game thinks you're no
longer inbounds (because it no longer thinks you're in a tower and thus
considers coordinates in the space of 40x30 tiles to be inbounds instead
of 40x700 or 40x100 tiles to be inbounds), calls map.gotoroom(), which
resets the gamestate to 0. So if we're using the old system, it's better
to reset only as much as needed.
And furthermore, we shouldn't be relying on script.hardreset() to
initialize variables for us. That should be done at the class
constructor level. So I've gone ahead and initialized the variables in
class constructors, too.
Looks like mapclass::changefinalcol() is called whenever you enter a
room in Outside Dimension VVVVVV.
mapclass::changefinalcol() changes the tile, but it doesn't update their
drawframe. So after that function is called, update their drawframe.
If you update their drawframe while inside that function, then when the
platform actually cycles color it'll cycle backwards quickly sometimes,
which is not ideal.
When I loaded the room where Vitellary is in Space Station 2, I saw this
1-frame glitch happen despite my previous efforts to prevent it. So now
it's fixed.
By "hidden names", I'm referring to "Dimension VVVVVV" and "The Ship"
popping up on the quit/pause/teleporter screens, even though those rooms
don't have any roomnames.
Apparently my commit to fix roomname re-draw bleed on the
quit/pause/teleporter screens exposed yet another hardreset()-caused
bug. The issue here is that since hardreset() sets game.roomx and
game.roomy to 0, map.area() will no longer work properly, and since the
hidden roomname check is based on map.area(), it will no longer display
"Dimension VVVVVV" or "The Ship" once you press ACTION to quit. It used
to do this due to the re-draw bleed, but now it doesn't.
I saw that roomnames didn't get reset in hardreset(), so the solution
here is to re-factor hidden names to be an actual variable, instead of
being implicit. map.hiddenname is a variable that's set in
mapclass::loadlevel(), and if isn't empty, it will be drawn on the
quit/pause/teleporter screens. That way it will still display "Dimension
VVVVVV" and "The Ship" when you press ACTION to quit to the menu.
EDIT: Since PR #230 got merged, this commit is no longer strictly
necessary, but it's still good to refactor hidden names like this.
This was especially noticeable in slowmode, where after going to an
adjacent room, it would look like they stopped for a split second. This
commit makes it so they smoothly continue their journey after switching
rooms.
The integer cast is to round off any fractional part of the velocity so
that they don't make a difference and result in the oldxp/oldyp being
one pixel off. Especially since the player's y-velocity fluctuates while
standing unflipped on the floor.
Incidentally enough, this seems to only have been a problem with screen
transitions for some reason. No other uses of gotoroom() (such as the
one where gotoroom() is called every other frame, or every frame) seem
to have resulted in this "pausing" behavior, or at least a reversion
back to 30 FPS movement. I don't know why.
Just a small thing, but if you teleported out of a tower with the
top/bottom screen spikes being onscreen (by dying, for example), they
would retract once you went back in to a tower. Small little thing, but
it's a good thing to polish.
By "frame" here I'm referring to the fixed-timestep, not a visual
delta-timestep.
Anyway, the problem is because crewmates' drawframes wait for
entityclass::animateentities() to be called in gamelogic(). In the
old, 30-FPS-only system, this entityclass::animateentities() would be
called in gamerender(), before any actual rendering would take place.
However, I've had to move it out of gamerender() because otherwise
entities would animate too fast. As a result, since gamerender() could
be called in between the entity creation and gamelogic(), a
less-than-1-frame visual glitch could happen.
The solution is to set the entity's drawframe as well when fixing facing
the player in Map.cpp.
Looks like duplicate player entities persisting across rooms is a
semi-useful feature used by some levels. Still, though, it's a bit of a
nuisance to have duplicate player entities persisting across game
sessions. And levels can't rely on this persistence anyway, anyone could
just close the game and re-open it to get rid of the duplicate entities
regardless.
The only class that actually needs its i/j/k kept is scriptclass,
because some custom levels rely on it for creating custom activity
zones. So I haven't touched that.
Other than that, there's no chance that anything important relies on
i/j/k in any other class. For that to be the case, it would have to use
i/j/k without initializing it beforehand, and that can simply be
detected by removing the attribute from the header file and seeing where
the compiler complains. And the compiler complains only about cases
where it's initialized first. (Note that due to this check, I *haven't*
removed Graphics's `m` as it precisely does exactly this, using it
without initializing it first.)
Interestingly enough, otherlevelclass and towerclass have unused i/k
variables for whatever reason.
obj.getplayer() can return -1, which can cause out-of-bounds indexing of
obj.entities, which is really bad. This was by far the most changes, as
obj.getplayer() is the most used entity-getting function that returns
-1, as well as the most-used function whose sentinel value goes
unchecked.
To deal with the usage of obj.getplayer() in mapclass::warpto(), I just
added general bounds checks inside that function instead of changing all
the callers.
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.
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.
Previously, it was used to parse 30 strings whenever loading a room. But
now it's no longer used since we just assign the tilemap to the vector
directly.
They are now stored in const int arrays instead. Except for the Prize
for the Reckless room, which I made sure had its spikes removed in No
Death Mode and the Time Trial.
Instead, they're all stored in a constant int array.
I made sure The Gravitron still has 30 rows just like Outer Space,
though I don't think it matters.
It's a bit annoying how vvvvvvman status is preserved between in-game
sessions, and the only thing reset is the color. This is annoying
because it means you have to close the game to reset vvvvvvman.
But now it'll be reset properly. I chose to put this reset code in
mapclass::resetplayer() instead of scriptclass::hardreset() because it
seemed like the more appropriate place. It's where all other properties
of the player are reset, after all.
Looks like there wasn't a custommode check for the spawning of crewmates
based on which crewmates were rescued, but now there is.
This has gone undiscovered for a long time, mostly because people don't
use the rescued() internal command.
I don't know why you would have to have both defined simultaneously, but
now you can.
The compile fail was caused by the fact that if both were defined, then
there would be an expression like this in Map.cpp:
switch (t)
{
case 0:
}
which is an invalid expression.
The solution is to put 'case 0:' into the MAKEANDPLAY ifdef-guard as
well.
