If you died in (11,7) and a moving platform was to the left of the line
x=152, even if it was moving vertically it would get snapped to x=152,
in custom levels.
Surprised nobody has ran into this before (although people have ran into
the other kludge, which is placing tile 59 at [18,9] if you're in a room
on either the line x=11 or y=7).
If you looked at the "- Press ENTER to Teleport -" text in flip mode,
you might have noticed that the outline looked pretty strange and
glitched-out for some reason. It's just the outline rendering
upside-down. To fix this, make PrintOff() use flipbfont instead of
bfont.
The problem with flipme() was that it WAS properly reflecting
("reflecting" as in mirroring over a given line) the text box over the
line y=120, BUT it forgot to account for the height of the text box.
Thus, the text box position would be off by the length of its own
height. And when the text box got taller, this offset would worsen and
worsen.
In flip mode, warping entities would appear to change color for a brief
moment. This is actually them defaulting to the actual color used in
flipsprites.png, instead of first being whited-out and then re-colored
using graphics.setcol().
To fix this, use BlitSurfaceColoured() and pass `ct` along instead of
using BlitSurfaceStandard().
If you died in Prize for the Reckless, which is at (11,7), and respawned
in the same room, tile 59 (a solid invisible tile) would be placed at
[18,9] to prevent the moving platform from going back through the
quicksand.
Unfortunately, the way that this kludge was added is poor.
First, the conditional makes it so that it doesn't happen in ONLY
(11,7). Instead of being behind a positive conditional, the tile is
placed in the else-branch of an if-conditional that checks for the
normal case, i.e. if the current room is NOT (11,7), thus being a
negative conditional.
In other words, the positive conditional is "game.roomx == 111 &&
game.roomy == 107". To negate it, all you would have to do is
"!(game.roomx == 111 && game.roomy == 107)".
However, whoever wrote this decided to go one step further, and actually
DISTRIBUTE the negative into both statements. This would be fine, except
if they actually got it right. You see, according to De Morgan's laws,
when you distribute a negative across multiple statements you not only
have to negate the statements themselves, but you have to negate all the
CONJUNCTIONS, too. In other words, you have to change all "and"s into
"or"s and all "or"s into "and"s.
Instead of making the conditional "game.roomx != 111 || game.roomy !=
107", the person who wrote this forgot to replace the "and" with an
"or". Thus, it is "game.roomx != 111 && game.roomy != 107" instead. As a
result, if we re-negate this and take a look at the positive
conditional, i.e. the conditional that results in the else-branch
executing, it turns out to be "game.roomx == 111 || game.roomy == 107".
This ends up forming a cross-shape of rooms where this kludge happens.
As long as your room is either on the line x=11 or on the line y=7, this
kludge will execute.
You can see this if you go to Boldly To Go, since it is (11,13), which
is on the line x=11. Checkpoint in that room, then touch a disappearing
platform, wait for it to fully disappear, then die. Then an invisible
tile will be placed to the left of the spikes on the ceiling.
Anyway, to fix this, it's simple. Just change the "and" in the negative
conditional to an "or".
The second problem was that this kludge was happening in custom levels.
So I've added a map.custommode check to it. I made sure not to make the
same mistake originally made, i.e. I made sure to use an "or" instead of
an "and". Thus, when you re-negate the negative conditional and turn it
into the positive conditional, it reads: "game.roomx == 111 &&
game.roomy == 107 && !map.custommode".
(19,8) is hardcoded to warp on all-sides no matter what. This is fine,
except for the fact that it was doing this in custom levels, too, even
despite the fact that the warp background and color would be overridden
anyway. The only workaround was to add a warp line to the room in custom
levels. I've added a check for custommode so that this won't happen.
The game uses magic values x=-500 and y=-500 to indicate when a text box
should be centered horizontally or vertically. It does this for x=-1
too, but it's buggy because it only looks at the first line of the text
box to center it. In this commit I fix it so that it will look at all of
the lines of the text box to center it instead.
This fixes a bug where warp lines created through createentity wouldn't
work without there already being a warp line present in the room as an
edentity.
This fixes a bug where if warpdir() was used during in-editor
playtesting, the changed warp direction would persist even when leaving
playtesting.
This would be very annoying to correct back every time you playtested
and warpdir() was used, so I've added some kludge to store the actual
warp direction of each room when entering playtesting, and then set the
warp directions back when leaving playtesting.
This commit makes `help`, `graphics`, `music`, `game`, `key`, `map`, and
`obj` essentially static global objects that can be used everywhere.
This is useful in case we ever need to add a new function in the future,
so we don't have to bother with passing a new argument in which means we
have to pass a new argument in to the function that calls that function
which means having to pass a new argument into the function that calls
THAT function, etc. which is a real headache when working on fan mods of
the source code.
Note that this changes NONE of the existing function signatures, it
merely just makes those variables accessible everywhere in the same way
`script` and `ed` are.
Also note that some classes had to be initialized after the filesystem
was initialized, but C++ would keep initializing them before the
filesystem got initialized, because I *had* to put them at the top of
`main.cpp`, or else they wouldn't be global variables.
The only way to work around this was to use entityclass's initialization
style (which I'm pretty sure entityclass of all things doesn't need to
be initialized this way), where you actually initialize the class in an
`init()` function, and so then you do `graphics.init()` after the
filesystem initialization, AFTER doing `Graphics graphics` up at the
top.
I've had to do this for `graphics` (but only because its child
GraphicsResources `grphx` needs to be initialized this way), `music`,
and `game`. I don't think this will affect anything. Other than that,
`help`, `key`, and `map` are still using the C++-intended method of
having ClassName::ClassName() functions.
This has two benefits:
(1) The game uses less resources when it is asked to gotoroom to the
same room because it is no longer redrawing the warp background
every single frame, which is very wasteful.
(2) The warp background no longer freezes or flickers if the player is
standing inside a gotoroom script box (which calls gotoroom every
frame or every other frame, because every time the gotoroom happens
the script box gets reloaded).
This is to make sure that the room data of those areas are not
distributed with the M&P binary, even if they are already inaccessible
because of other M&P ifdefs (I tested).
FillRect() is similar enough to memset when blending isn't used, so the
game will take a fast path drawing the roomname background when the
background is opaque.
This is the variable dwgfx.translucentroomname and <translucentroomname>
in unlock.vvv.
This lets you see through the black background of the roomname at the
bottom of the screen, i.e. it makes the roomname background translucent.
So you can see if someone decides to hide pesky spikes there.
The roomname background used to just be a simple SDL_Rect that was drawn
using SDL_FillRect with a color of 0. Unfortunately, it seems that you
cannot use transparent colors with SDL_FillRect, it just defaults to
being fully opaque. However, you CAN draw surfaces with translucency,
which seems like the easiest thing to do. But the first step is to
convert the roomname background to an SDL_Surface.
This replaces the FillRect()s with SDL_BlitSurface() in the three places
roomnames are drawn: in towerrender, in gamerender, and in editorrender.
For some reason, there are two lines that have been copy-pasted the
exact same way and in the exact same place, namely being at the end of
each branch of the if-else conditional, which makes them be executed no
matter what. If they're going to be executed no matter what, we might as
well make it clearer and take those two lines out of each branch.
Previously, if it was called in a custom level, it would say "out of
Twenty" no matter what, even if the level had zero trinkets. This commit
fixes that.
Previously, it was a hardcoded list going up to fifty.
This time, it's less hardcoded. Most of the time, it will take a number,
find out its tens-place word, find out its ones-place word, and combine
the two together. There are special cases for the teens, and the numbers
zero through nine, and one hundred.
Also, now if it is given a negative value, it will just return "???"
instead.
If there are more than one hundred it will still say "Lots".
2.2 will handle this just fine, because there are 100 slots allocated
for trinkets and crewmates, and it will save and load all 100 slots just
fine. Except, it only resets the first 20 slots when starting a level
from the beginning, but that's minor and already fixed in 2.3 anyway.
This commit makes it so you can now place up to one hundred trinkets and
crewmates in the editor.
When editorclass::reset() was resetting the contents of the level
previously, it was mixing up the X and Y bounds. The Y bound was
supposed to be 30*maxheight, and the X bound was supposed to be
40*maxwidth. Instead, it took 30*maxwidth as its Y bound and
40*maxheight as its X bound.
Then, when it actually indexes the contents vector to set each tile to
0, it used 30*maxwidth instead of 40*maxwidth.
The difference between width and height is a bit hard to spot, but one
thing you can do to remember the difference is to remember the fact that
X corresponds with width, and Y corresponds with height. Also, rooms are
40 by 30 tiles, and so X (and therefore width) should correspond with
40, and Y (and therefore height) should correspond with 30.
As a result of mixing up the variables, whenever you played a 20x20 map,
quit the level and then started making a new 20x20 map, the tiles of the
last four rows of the previous map would persist, from y=16 (1-indexed)
all the way to y=20 (1-indexed).
I don't recall anyone ever running into this bug before, which is a bit
strange. But if no one truly has ever ran into this bug before, then I'm
genuinely surprised.
While working on the patch to fix the enemy type room property of each
room not getting reset, and testing the fix, I noticed that for some
reason some contents of the previous level I played in order to test the
enemy type property persisting was ALSO persisting alongside the enemy
type property.
Then I read the code and when I realized that the X and Y bounds were
getting mixed up I groaned. Very loudly.
This fixes a bug where if you loaded a level, then started making a new
level in the editor, the enemy types from the previous level would
persist.
While working on VVVVVV: Community Edition and adding a new room
property for enemy speed, I noticed that enemy type was not getting
reset at all. After some testing, I confirmed that this was the case. So
this bug is fixed now.
This fixes a bug where you could get mismatched text and background
colors on the menu screen by being in the Tower and exiting at a certain
time. The background when mismatched will always be red, which seems to
have something to do with the fact that when you enter the Tower the
game always sets the background to be red. I could get a quick repro
setup going by starting in the checkpoint in Teleporter Divot, then
quickly entering the Tower, exiting, then re-entering, then pressing Esc
and quitting - all done very quickly.
The important thing about this mismatch is that it's only temporary, and
will be corrected when you press ACTION and the color of the text and
background in the menu both change at the same time, which is what
map.nexttowercolour() does. So all I do is simply call that function
when exiting to the menu, and it will fix the color mismatch.
Earlier in 53950e14de65a54d9369c5183a16337782d3dc4e, I made playing a
song while a song was already fading quickly fade out the current song,
but then added an exception for if the fade came from the musicfadeout()
command. This commit adds another exception for if the fade came from
niceplay(), since otherwise the music transitions between areas in the
game would go too quick.
This fixes an issue where you could softlock the game if you exited
playtesting mode by pressing Esc while a "- Press ACTION to advance text
-" prompt was onscreen, then re-entered playtesting and then started any
script.
The "- Press ACTION to advance text -" prompt is most directly
controlled by game.advancetext, but when it appears game.pausescript is
usually set as well. You need to have both variables on at the same time
in order to press ACTION. If only advancetext is on, then you won't be
able to flip but can still move around, but if only pausescript is on,
then the game softlocks because the only way you can turn pausescript
off is by pressing ACTION, but the game will only let you press ACTION
if *both* advancetext and pausescript are on.
This fixes a bug where bringing up the pause screen while in a tower
would draw the room you entered BEFORE the tower during the time it took
for the pause screen to be brought up or down.
This fixes a bug in the editor where if you had cutscene bars active
while exiting playtesting, when you re-entered playtesting, the bars
would do their closing animation even though they should be already
gone.
Out-of-bounds array access is Undefined Behavior, which means Bad
Things.
In this particular case, it was indexing an array by using the
`testeditor` variable. Which is fine, except it was indexing that array
*in a conditional that only happens if `testeditor` is -1*. So it was
indexing an array at position -1, which is Out of Bounds and is Not
Good.
For a long time, VVVVVV has had an issue where if you used custom
graphics with translucent pixels (i.e. pixels whose opacity was neither
0% nor 100%, but somewhere between 0% and 100%), those pixels would end
up looking very ugly. They seemed to be overlaid on top of some weird
blue color, instead of actually being translucent.
This bug only occurred when in-game and not in towermode. So, most of
the time, basically. The translucent pixels only displayed properly
inside the Tower, both minitowers, and the editor (when not
playtesting).
I traced this down to the use of the magic number 0xDEADBEEF in
Graphics::drawmap() and Graphics::drawfinalmap(). Looks like someone had
fun finding a color. Was it you, simoroth? Anyway, I've changed it so it
simply uses 0 instead. Note that this magic number needs to be changed
for BOTH FillRect() and OverlaySurfaceKeyed(), or else the game's
background will be some random solid color instead of actually being
drawn properly.
There's a long-standing issue where the Direct Mode status of the loaded
custom map in memory never resets properly. So if you load a level with
a certain layout of Direct Mode rooms, that same layout will be
preserved if you start making a new level in the editor. This commit
fixes that issue.
Similar to 2ebccbc3e9, there's also a
long-standing bug where if you backspace an empty line (and this time,
the line IS actually already empty, not merely
emptied-earlier-in-the-frame), the game will quickly delete more blank
lines if there are any above the blank line you deleted. Again, this is
annoying too, if you so happen to need to use lots of blank lines.
To fix this, it's simple - just set ed.keydelay to 6 when the game
backspaces an empty line. Then it won't be so trigger-happy in deleting
blank lines.
There is a long-standing bug with the script editor where if you delete
the last character of a line, it IMMEDIATELY deletes the line you're on,
and then moves your cursor back to the previous line. This is annoying,
to say the least.
The reason for this is that, in the sequence of events that happens in
one frame (known as frame ordering), the code that backspaces one
character from the line when you press Backspace is ran BEFORE the code
to remove an empty line if you backspace it is ran. The former is
located in key.Poll(), and the latter is located in editorinput().
Thus, when you press Backspace, the game first runs key.Poll(), sees
that you've pressed Backspace, and dutifully removes the last character
from a line. The line is now empty. Then, when the game gets around to
the "Are you pressing Backspace on an empty line?" check in
editorinput(), it thinks that you're pressing Backspace on an empty
line, and then does the usual line-removing stuff.
And actually, when it does the check in editorinput(), it ACTUALLY asks
"Are you pressing Backspace on THIS frame and was the line empty LAST
frame?" because it's checking against its own copy of the input buffer,
before copying the input buffer to its own local copy. So the problem
only happens if you press and hold Backspace for more than 1 frame.
It's a small consolation prize for this annoyance, getting to
tap-tap-tap Backspace in the hopes that you only press it for 1 frame,
while in the middle of something more important to do like, oh I don't
know, writing a script.
So there are two potential solutions here:
(1) Just change the frame ordering around.
This is risky to say the least, because I'm not sure what behavior
depends on exactly which frame order. It's not like it's key.Poll()
and then IMMEDIATELY afterwards editorinput() is run, it's more
like key.Poll(), some things that obviously depend on key.Poll()
running before them, and THEN editorinput(). Also, editorinput() is
only one possible thing that could be ran afterwards, on the next
frame we could be running something else entirely instead.
(2) Add a kludge variable to signal when the line is ALREADY empty so
the game doesn't re-check the already-empty line and conclude that
you're already immediately backspacing an empty line.
I went with (2) for this commit, and I've added the kludge variable
key.linealreadyemptykludge.
However, that by itself isn't enough to fix it. It only adds about a
frame or so of delay before the game goes right back to saying "Oh,
you're ALREADY somehow pressing backspace again? I'll just delete this
line real quick" and the behavior is basically the same as before,
except now you have to hit Backspace for TWO frames or less instead of
one in order to not have it happen.
What we need is to have a delay set as well, when the game deletes the
last line of a char. So I set ed.keydelay to 6 as well if editorinput()
sses that key.linealreadyemptykludge is on.
For a long time, the script editor has had a bug where it would let you
put the cursor on a nonexistent script line, which would APPEAR to be
the last line of the script... but in reality, it WASN'T the last line
of the script, and in fact, the ACTUAL last line was the line ABOVE the
script.
So, if you typed anything on this nonexistent line, it would appear to
get erased when exiting the script. Thus, people have (erroneously)
misdiagnosed this as the script editor somehow being trigger-happy and
erasing lines when it shouldn't be, when in reality it should've have
let you gone onto that line in the first place!
If you're in the room being targeted when a `warpdir()` command is run,
and it sets the warp direction to none (warp dir 0), and if you're in a
Lab or Warp Zone room, the background will be set to the wrong one,
because it will always set the background to the stars-going-left
background, instead of setting it to the Lab background or the
stars-going-up background.
However, this is only a visual glitch, and is a temporary one, because
if you manage to trigger a `gotoroom()` on the room, it will get set to
its proper background.
This commit makes it so if you're in a Lab room, the background gets set
to the Lab background, and if you're in a Warp Zone room, the background
gets set to the stars-going-up background.
There are three map-related vectors that need to be reset in hardreset:
`map.roomdeaths`, `map.roomdeathsfinal`, and `map.explored`. All three
of these vectors use the concatenated rows system, whereby each room is
given a room number, calculated by doing X + Y*20, and this becomes
their index in each vector.
There's a double-nested for-loop to handle resetting all of these, where
the outer for-loop iterates over the Y-axis and the inner for-loop
iterates over the X-axis, but only `map.explored` is properly reset.
That's because it's the only vector that properly indexes using X +
Y*20. The other vectors reset using X, so previously, only the first row
of `map.roomdeaths` and `map.roomdeathsfinal` got reset, corresponding
with only the first row of rooms in both Dimension VVVVVV and Outside
Dimension VVVVVV getting reset.
This commit makes sure that both get reset properly.
For reference, here is the list of scores for a custom level:
0 - not played
1 - finished
2 - all trinkets
3 - finished, all trinkets
Previously, you could've played a level and finished it and set a score
of 3. Then you could re-play the entire level, but manage to only get a
score of 1, i.e. only finished but not with all trinkets. Then your
score for that level would get set back to 1, which basically nullifies
the time you spent playing that level and getting all of the trinkets.
This commit makes it so your new score will get set only if it is higher
than the previous one.
This disables being able to press M to mute while editing a script in
the script editor. It also disables it in the script list, too, but I'm
hoping no one thinks that's an issue, because I personally don't think
it is.
This fixes a bug where if you died after activating a teleporter prompt
and then respawned in the same room as the teleporter, the teleporter
prompt would go away. Which would be very annoying if you wanted to, you
know, teleport.
You don't even have to R-press to make this happen. "Level Complete!"
and Energize are two teleporter rooms in the main game that have hazards
in them.
I see no reason to set game.activetele to false when dying. For one, it
gets set to false during a gotorom anyway. For another, I couldn't get
the game to activate the teleport prompt in a room without a teleporter
in my testing, mostly because when you touch a teleporter, your
checkpoint is set to that teleporter, so you can't R-press to go to
another room and carry over the teleport prompt.
This uncomments the code for the font outline. Now, you will see the
font outline on text that had it in the Flash version, most notably "-
Press ENTER to Teleport -" and the time trial overlay text.
This also fixes a problem with the commented code, where un-centered
text didn't outline properly.
The game makes sure that the player entity is never destroyed, but in
doing so, it doesn't destroy any duplicate player entities that might
have been created via strange means e.g. a custom level doing a
createentity with t=0.
Duplicate player entities are, in a sense, not the "real" player entity.
For one, they can take damage and die, but when they do they'll still be
stuck inside the hazard, which can result in a softlock. For another,
their position isn't updated when going between rooms. It's better to
just destroy them when we can.
