Reduce dependency on libc functions During 2.3 development, there's been a gradual shift to using SDL stdlib functions instead of libc functions, but there are still some libc functions (or the same libc function but from the STL) in the code. Well, this patch replaces all the rest of them in one fell swoop. SDL's stdlib can replace most of these, but its SDL_min() and SDL_max() are inadequate - they aren't really functions, they're more like macros with a nasty penchant for double-evaluation. So I just made my own VVV_min() and VVV_max() functions and placed them in Maths.h instead, then replaced all the previous usages of min(), max(), std::min(), std::max(), SDL_min(), and SDL_max() with VVV_min() and VVV_max(). Additionally, there's no SDL_isxdigit(), so I just implemented my own VVV_isxdigit(). SDL has SDL_malloc() and SDL_free(), but they have some refcounting built in to them, so in order to use them with LodePNG, I have to replace the malloc() and free() that LodePNG uses. Which isn't too hard, I did it in a new file called ThirdPartyDeps.c, and LodePNG is now compiled with the LODEPNG_NO_COMPILE_ALLOCATORS definition. Lastly, I also refactored the awful strcpy() and strcat() usages in PLATFORM_migrateSaveData() to use SDL_snprintf() instead. I know save migration is getting axed in 2.4, but it still bothers me to have something like that in the codebase otherwise. Without further ado, here is the full list of functions that the codebase now uses: - SDL_strlcpy() instead of strcpy() - SDL_strlcat() instead of strcat() - SDL_snprintf() instead of sprintf(), strcpy(), or strcat() (see above) - VVV_min() instead of min(), std::min(), or SDL_min() - VVV_max() instead of max(), std::max(), or SDL_max() - VVV_isxdigit() instead of isxdigit() - SDL_strcmp() instead of strcmp() - SDL_strcasecmp() instead of strcasecmp() or Win32 strcmpi() - SDL_strstr() instead of strstr() - SDL_strlen() instead of strlen() - SDL_sscanf() instead of sscanf() - SDL_getenv() instead of getenv() - SDL_malloc() instead of malloc() (replacing in LodePNG as well) - SDL_free() instead of free() (replacing in LodePNG as well)

Fix text box deltaframe flashing on deltaframes after fully opaque So #434 didn't end up solving the deltaframe flashing fully, only reduced the chances that it could happen. I've had the Level Complete image flash a few times when the Game Saved text box pops up. This seems to be because the Level Complete image is based off of the text box being at y-position 12, and the Game Saved text box is also at y-position 12. Level Complete only gets drawn if the text box additionally has a red channel value of 165, and the Game Saved text box has a red channel value of 174. However, there is a check that the text box be fully opaque first before drawing special images. So what went wrong? Well, after thinking about it for a while, I realized that even though there is indeed an opaqueness check, the alpha of the text box updates BEFORE it gets drawn. And during the deltaframes immediately after it gets updated, the text box is considered fully opaque. It's completely possible for the linear interpolation to end up with a red channel value of 165 during these deltaframes, while the text box is opaque as well. As always, it helps if you have a high refresh rate, and run the game under 40% slowdown. Anyways, so what's the final fix for this issue? Well, use the text box 'target' RGB values instead - its tr/tg/tb attributes instead of its r/g/b attributes. They are not subject to interpolation and so are completely reliable. The opaqueness check should still be kept, though, because the target values don't account for opaqueness. And this way, we get no more deltaframe flashes during text box fades. An even better fix would be to not use magic RGB values to draw special images... but that'd be something to do later.

However, there is a check that the text box be fully opaque first before drawing special images. So what went wrong? Well, after thinking about it for a while, I realized that even though there is indeed an opaqueness check, the alpha of the text box updates BEFORE it gets drawn. And during the deltaframes immediately after it gets updated, the text box is considered fully opaque. It's completely possible for the linear interpolation to end up with a red channel value of 165 during these deltaframes, while the text box is opaque as well. As always, it helps if you have a high refresh rate, and run the game under 40% slowdown. Anyways, so what's the final fix for this issue? Well, use the text box 'target' RGB values instead - its tr/tg/tb attributes instead of its r/g/b attributes. They are not subject to interpolation and so are completely reliable. The opaqueness check should still be kept, though, because the target values don't account for opaqueness. And this way, we get no more deltaframe flashes during text box fades. An even better fix would be to not use magic RGB values to draw special images... but that'd be something to do later.

Fix text box deltaframe flashing on deltaframes after fully opaque So #434 didn't end up solving the deltaframe flashing fully, only reduced the chances that it could happen. I've had the Level Complete image flash a few times when the Game Saved text box pops up. This seems to be because the Level Complete image is based off of the text box being at y-position 12, and the Game Saved text box is also at y-position 12. Level Complete only gets drawn if the text box additionally has a red channel value of 165, and the Game Saved text box has a red channel value of 174.

Reduce dependency on libc functions During 2.3 development, there's been a gradual shift to using SDL stdlib functions instead of libc functions, but there are still some libc functions (or the same libc function but from the STL) in the code. Well, this patch replaces all the rest of them in one fell swoop. SDL's stdlib can replace most of these, but its SDL_min() and SDL_max() are inadequate - they aren't really functions, they're more like macros with a nasty penchant for double-evaluation. So I just made my own VVV_min() and VVV_max() functions and placed them in Maths.h instead, then replaced all the previous usages of min(), max(), std::min(), std::max(), SDL_min(), and SDL_max() with VVV_min() and VVV_max(). Additionally, there's no SDL_isxdigit(), so I just implemented my own VVV_isxdigit(). SDL has SDL_malloc() and SDL_free(), but they have some refcounting built in to them, so in order to use them with LodePNG, I have to replace the malloc() and free() that LodePNG uses. Which isn't too hard, I did it in a new file called ThirdPartyDeps.c, and LodePNG is now compiled with the LODEPNG_NO_COMPILE_ALLOCATORS definition. Lastly, I also refactored the awful strcpy() and strcat() usages in PLATFORM_migrateSaveData() to use SDL_snprintf() instead. I know save migration is getting axed in 2.4, but it still bothers me to have something like that in the codebase otherwise. Without further ado, here is the full list of functions that the codebase now uses: - SDL_strlcpy() instead of strcpy() - SDL_strlcat() instead of strcat() - SDL_snprintf() instead of sprintf(), strcpy(), or strcat() (see above) - VVV_min() instead of min(), std::min(), or SDL_min() - VVV_max() instead of max(), std::max(), or SDL_max() - VVV_isxdigit() instead of isxdigit() - SDL_strcmp() instead of strcmp() - SDL_strcasecmp() instead of strcasecmp() or Win32 strcmpi() - SDL_strstr() instead of strstr() - SDL_strlen() instead of strlen() - SDL_sscanf() instead of sscanf() - SDL_getenv() instead of getenv() - SDL_malloc() instead of malloc() (replacing in LodePNG as well) - SDL_free() instead of free() (replacing in LodePNG as well)

Reduce dependency on libc functions During 2.3 development, there's been a gradual shift to using SDL stdlib functions instead of libc functions, but there are still some libc functions (or the same libc function but from the STL) in the code. Well, this patch replaces all the rest of them in one fell swoop. SDL's stdlib can replace most of these, but its SDL_min() and SDL_max() are inadequate - they aren't really functions, they're more like macros with a nasty penchant for double-evaluation. So I just made my own VVV_min() and VVV_max() functions and placed them in Maths.h instead, then replaced all the previous usages of min(), max(), std::min(), std::max(), SDL_min(), and SDL_max() with VVV_min() and VVV_max(). Additionally, there's no SDL_isxdigit(), so I just implemented my own VVV_isxdigit(). SDL has SDL_malloc() and SDL_free(), but they have some refcounting built in to them, so in order to use them with LodePNG, I have to replace the malloc() and free() that LodePNG uses. Which isn't too hard, I did it in a new file called ThirdPartyDeps.c, and LodePNG is now compiled with the LODEPNG_NO_COMPILE_ALLOCATORS definition. Lastly, I also refactored the awful strcpy() and strcat() usages in PLATFORM_migrateSaveData() to use SDL_snprintf() instead. I know save migration is getting axed in 2.4, but it still bothers me to have something like that in the codebase otherwise. Without further ado, here is the full list of functions that the codebase now uses: - SDL_strlcpy() instead of strcpy() - SDL_strlcat() instead of strcat() - SDL_snprintf() instead of sprintf(), strcpy(), or strcat() (see above) - VVV_min() instead of min(), std::min(), or SDL_min() - VVV_max() instead of max(), std::max(), or SDL_max() - VVV_isxdigit() instead of isxdigit() - SDL_strcmp() instead of strcmp() - SDL_strcasecmp() instead of strcasecmp() or Win32 strcmpi() - SDL_strstr() instead of strstr() - SDL_strlen() instead of strlen() - SDL_sscanf() instead of sscanf() - SDL_getenv() instead of getenv() - SDL_malloc() instead of malloc() (replacing in LodePNG as well) - SDL_free() instead of free() (replacing in LodePNG as well)

Fix crewmates being drawn behind other entities This fixes the draw order by drawing all other entities first, before then drawing all humanoids[1] after, including the player afterwards. This is actually a regression fix from #191. When I was testing this, I was thinking about where get a crewmate in front of another entity in the main game, other than the checkpoints in Intermission 1. And then I thought about the teleporters, because I remember the pre-Deep Space cutscene in Dimension Open looking funny because Vita ended up being behind the teleporter. (Actually, a lot of the cutscenes of Dimension Open look funny because of crewmates standing behind terminals.) So then I tried to get crewmates in front of teleporters. It actually turns out that you can't do it for most of them... except for Verdigris. And then that's what I realized why there was an oddity in WarpClass.cpp when I was removing the `active` system from the game - for some reason, the game put a hole in `obj.entities` between the teleporter and the player when loading the room Murdering Twinmaker. In a violation of Chesterton's Fence (the principle that you should understand something before removing it), I shrugged it off and decided "there's no way to support having holes with my new system, and having holes is probably bad anyway, so I'm going to remove this and move on". The fact that there wasn't any comments clarifying the mysterious code didn't help (but, this *was* 2.2 code after all; have you *seen* 2.2 code?!). And it turns out that this maneuver was done so Verdigris would fill that hole when he got created, and Verdigris being first before the teleporter would mean he would be drawn in front of the teleporter, instead of being behind it. So ever since b1b1474b7bbc3ceddea24f689a7ddb050cfe4490 got merged, there has actually been a regression from 2.2 where Verdigris got drawn behind the teleporter in Murdering Twinmaker, instead of properly being in front of it like in 2.2 and previous. This patch fixes that regression, but it actually properly fixes it instead of hacking around with the `active` system. Closes #426. [1]: I'm going to go on a rant here, so hear me out. It's not explicitly stated that the characters in VVVVVV are human. So, given this information, what do we call them? Well, the VVVVVV community (at least the custom levels one, I don't think the speedrunning community does this or is preoccupied with lore in the first place) decided to call them "villis", because of the roomname "The Villi People" - which is only one blunder in a series of awful headcanons based off of the assumption that the intent of Bennett Foddy (who named the roomnames) was to decree some sort of lore to the game. Another one being "Verdigris can't flip" because of "Green Dudes Can't Flip". Then an OC (original character) got named based off of "The Voon Show" too. And so on and so forth.

Add and draw one more row to all rooms with roomnames Since translucent roomname backgrounds were introduced in TerryCavanagh/VVVVVV#122, it exposes one glaring flaw with the game that until now has been kept hidden: in rooms with room names, the game cheapens out with the tile data and doesn't have a 30th row, because the room name would hide the missing row. As a result, rooms with room names have 29 rows instead of 30 to fill up the entire screen. And it looks really weird when there's nothing but empty space behind the translucent room name background. To remedy this, I added one row to each room with a room name in the level. First, I had to filter out all the rooms with no room names. However, that's actually all contained in Otherlevel.cpp, the Overworld, which contains 221 rooms (8 of which are the Secret Lab, 6 more of which are the Ship, so 207 are the actual Overworld, right? Wrong, 2 of those Overworld no-roomname rooms are in the Lab, so there are actually 205 Overworld rooms). The remaining level data files all contain rooms with room names. But the process wasn't that easy. I noticed a while ago that each room contains 29 `tmap.push_back()`s, one for each row of the room, and each row is simply a string containing the 40 tiles for that row, concatenated with commas. However, I decided to actually check my intuition by doing a grep on each level file and counting the number of results, for example `grep 'push_back' Labclass.cpp | wc -l`. Whatever number comes out should be divisible by 29. That particular grep on Labclass.cpp returns 1306, which divided by 29 is 45 with a remainder of 1. So what does that mean? Does that mean there's 45 rooms each, and 1 leftover row? Well, not exactly. The extra row comes from the fact that Outer Space has 30 rows instead of 29. Outer Space is the room that comes up when the game finds a room is non-existent, which shouldn't happen with a properly-working game, except in Outside Dimension VVVVVV. In fact, each level file has their own Outer Space, and every single Outer Space also has 30 rooms. So really, this means there are 44 rooms in the Lab and one Outer Space room. (Well, in reality, there are 46 rooms in the Lab, because 2 of them use the Outside tileset but have no room names, so they're stored in Otherlevel.cpp instead.) We find the same result for the Warp Zone. `grep 'push_back' WarpClass.cpp | wc -l` returns 697, which is 24 remainder 1, meaning 23 rooms of 29 rows and 1 room of 30 rows, which corresponds with 23 rooms in the Warp Zone and one Outer Space room. However, Outside Dimension VVVVVV + Tower Hallways and Space Station 1 and 2 are both odd curiosities. Finalclass.cpp contains Outside Dimension VVVVVV, (which is Intermission 1 and 2 and the Final Level), but also the Tower Hallway rooms, i.e. the auxiliary Tower rooms that are not a part of the main tower. Spacestation2.cpp contains both Space Station 1 and 2, so don't be deceived by the name. `grep 'push_back' Finalclass.cpp | wc -l` returns 1597, which is actually 55 remainder 2. So... are there two rooms with 30 rows? Yes, in fact, The Gravitron and Outer Space both contain 30 rows. So there are actually 55 rooms stored in Finalclass.cpp (not including the minitowers Panic Room and The Final Challenge), 54 rooms of actual level data and one Outer Space room, and breaking down the 54 rooms even further, 51 of them are actually in Outside Dimension VVVVVV and 3 of them are Tower Hallways. Of the 51 Outside Dimension VVVVVV rooms, 14 of those are Intermission 1, 4 of them are Intermission 2, and the rest of the 33 rooms are the Final Level (again, not including the minitowers). `grep 'push_back' Spacestation2.cpp | wc -l` returns 2148, which is 74 remainder 2. Are there two rooms with 30 rows again? No; one of those counted 2148 rows is a false-positive, because there's an if-else in Prize for the Reckless that replaces the row with spikes with a row without spikes if you are in a time trial or in No Death Mode. So there's 73 rooms in Space Station 1 and 2, and one Outer Space room. With all this in mind, I decided to duplicate the current last row of each room, the 29th row, to add a 30th row. However, I wasn't going to do this automatically! But neither was I going to write some kludge-y code to parse each nightmare of a level file and duplicate the rows that way. Enter: Vim macros! (Er, well, actually, I use Neovim.) I first did `/push_back`, so that pressing `n` would keep going to the next `push_back` in the file. Then I went to the 29th row of the first room in the file, did a `Yp`, and then started my macro with `qq`. The macro went like this: `30nYp`, which is simply going to the 29th row of the next room over and duplicating it. And that's all there was to it. However, I had to make sure that (1) my cursor was before the `push_back` on the line of the 29th row of the room, and (2) that I didn't skip rooms, both of which were problems I encountered when pressing Ctrl+Z a given invocation of the macro (the Ctrl+Z is just a metaphor, you actually undo by typing `u` in Vim). And also I had to make sure to be careful around the extra lines of `push_back`s in Prize for the Reckless and The Gravitron, and make sure I didn't run past the end of the file and loop back around. Thankfully, all Outer Space rooms are at the end of each file. But first, I had to increase the number of rows drawn in Graphics.cpp by 1 in order to compensate for this, and do the same when reading the tile data in Map.cpp. I had to change fillcontent(), drawmap(), drawfinalmap(), drawtowermap(), and drawtowermap_nobackground(). Funnily enough, the tower functions already used 30 rows, but I guess it's an off-by-one due to the camera scrolling, so they now draw 31 rows each. Then, I went in-game to make sure that the row behind each room name looked fine. I checked EVERY single room with a room name. I turned on invincibility mode and added a temporary line to hardreset() that always turned on game.nocutscenes for a smoother playtesting experience. And to make sure that rooms which have entirely empty bottom rows actually still have 30 rows, instead of having 29 and the game assuming that the 30th row was empty (because that sounds like it could lead to Undefined Behavior), I added this temporary debugging line to the start of mapclass::fillcontent(): printf("(%i,%i) has %i rows\n", game.roomx, game.roomy, (int) tmap.size()); Everywhere I checked - and I made sure to check all rooms - every room had 30 rows and not 29 rows. Unfortunately, some rooms simply couldn't be left alone with their 29th row duplicated and had to be manually edited. This was because the 29th row would contain some edge tiles because the player would be able to walk somewhere on the 28th, 27th, and 26th rows, and if you duplicated said edge tiles behind the room name, it would look bad. Here's a list of rooms whose 30th rows I had to manually edit: - Comms Relay - The Yes Men - Stop and Reflect - They Call Him Flipper - Double-slit Experiment - Square Root - Brought to you by the letter G - The Bernoulli Principle - Purest Unobtainium - I Smell Ozone - Conveying a New Idea - Upstream Downstream - Give Me A V - $eeing Dollar $ign$ - Doing Things The Hard Way - Very Good - Must I Do Everything For You? - Now Stay Close To Me... - ...But Not Too Close - ...Not as I Do - Do Try To Keep Up - Whee Sports - As you like it This is actually a strange case where it looked bad because of the 29th row, instead of the 30th row, and I had to change the 29th row instead of the 30th row to fix it. - Maze With No Entrance - Ascending and Descending - Mind The Gap Same strange case as "As you like it" (it's the 29th row I had to change that was the problem, not the 30th). - 1950 Silverstone Grand V - The Villi People I found that Panic Room and The Final Challenge also looked strange behind the roomname background, but I can't do much about either because towers' tile data wrap around at the top and bottom, and if I added another row to either it would be visible above the room name. I've considered updating the development editors with these new level tiles, but I decided against it as the development editors are already pretty outdated anyway.

Ax OverlaySurfaceKeyed(), set proper foregroundBuffer blend mode So, earlier in the development of 2.0, Simon Roth (I presume) encountered a problem: Oh no, all my backgrounds aren't appearing! And this is because my foregroundBuffer, which contains all the drawn tiles, is drawing complete black over it! So he had a solution that seems ingenius, but is actually really really hacky and super 100% NOT the proper solution. Just, take the foregroundBuffer, iterate over each pixel, and DON'T draw any pixel that's 0xDEADBEEF. 0xDEADBEEF is a special signal meaning "don't draw this pixel". It is called a 'key'. Unfortunately, this causes a bug where translucent pixels on tiles (pixels between 0% and 100% opacity) didn't get drawn correctly. They would be drawn against this weird blue color. Now, in #103, I came across this weird constant and decided "hey, this looks awfully like that weird blue color I came across, maybe if I set it to 0x00000000, i.e. complete and transparent black, the issue will be fixed". And it DID appear to be fixed. However, I didn't look too closely, nor did I test it that much, and all that ended up doing was drawing the pixels against black, which more subtly disguised the problem with translucent pixels. So, after some investigation, I noticed that BlitSurfaceColoured() was drawing translucent pixels just fine. And I thought at the time that there was something wrong with BlitSurfaceStandard(), or something. Further along later I realized that all drawn tiles were passing through this weird OverlaySurfaceKeyed() function. And removing it in favor of a straight SDL_BlitSurface() produced the bug I mentioned above: Oh no, all the backgrounds don't show up, because my foregroundBuffer is drawing pure black over them! Well... just... set the proper blend mode for foregroundBuffer. It should be SDL_BLENDMODE_BLEND instead of SDL_BLENDMODE_NONE. Then you don't have to worry about your transparency at all. If you did it right, you won't have to resort this hacky color-keying business. *sigh*

Add and draw one more row to all rooms with roomnames Since translucent roomname backgrounds were introduced in TerryCavanagh/VVVVVV#122, it exposes one glaring flaw with the game that until now has been kept hidden: in rooms with room names, the game cheapens out with the tile data and doesn't have a 30th row, because the room name would hide the missing row. As a result, rooms with room names have 29 rows instead of 30 to fill up the entire screen. And it looks really weird when there's nothing but empty space behind the translucent room name background. To remedy this, I added one row to each room with a room name in the level. First, I had to filter out all the rooms with no room names. However, that's actually all contained in Otherlevel.cpp, the Overworld, which contains 221 rooms (8 of which are the Secret Lab, 6 more of which are the Ship, so 207 are the actual Overworld, right? Wrong, 2 of those Overworld no-roomname rooms are in the Lab, so there are actually 205 Overworld rooms). The remaining level data files all contain rooms with room names. But the process wasn't that easy. I noticed a while ago that each room contains 29 `tmap.push_back()`s, one for each row of the room, and each row is simply a string containing the 40 tiles for that row, concatenated with commas. However, I decided to actually check my intuition by doing a grep on each level file and counting the number of results, for example `grep 'push_back' Labclass.cpp | wc -l`. Whatever number comes out should be divisible by 29. That particular grep on Labclass.cpp returns 1306, which divided by 29 is 45 with a remainder of 1. So what does that mean? Does that mean there's 45 rooms each, and 1 leftover row? Well, not exactly. The extra row comes from the fact that Outer Space has 30 rows instead of 29. Outer Space is the room that comes up when the game finds a room is non-existent, which shouldn't happen with a properly-working game, except in Outside Dimension VVVVVV. In fact, each level file has their own Outer Space, and every single Outer Space also has 30 rooms. So really, this means there are 44 rooms in the Lab and one Outer Space room. (Well, in reality, there are 46 rooms in the Lab, because 2 of them use the Outside tileset but have no room names, so they're stored in Otherlevel.cpp instead.) We find the same result for the Warp Zone. `grep 'push_back' WarpClass.cpp | wc -l` returns 697, which is 24 remainder 1, meaning 23 rooms of 29 rows and 1 room of 30 rows, which corresponds with 23 rooms in the Warp Zone and one Outer Space room. However, Outside Dimension VVVVVV + Tower Hallways and Space Station 1 and 2 are both odd curiosities. Finalclass.cpp contains Outside Dimension VVVVVV, (which is Intermission 1 and 2 and the Final Level), but also the Tower Hallway rooms, i.e. the auxiliary Tower rooms that are not a part of the main tower.

Wrong, 2 of those Overworld no-roomname rooms are in the Lab, so there are actually 205 Overworld rooms). The remaining level data files all contain rooms with room names. But the process wasn't that easy. I noticed a while ago that each room contains 29 `tmap.push_back()`s, one for each row of the room, and each row is simply a string containing the 40 tiles for that row, concatenated with commas. However, I decided to actually check my intuition by doing a grep on each level file and counting the number of results, for example `grep 'push_back' Labclass.cpp | wc -l`. Whatever number comes out should be divisible by 29. That particular grep on Labclass.cpp returns 1306, which divided by 29 is 45 with a remainder of 1. So what does that mean? Does that mean there's 45 rooms each, and 1 leftover row? Well, not exactly. The extra row comes from the fact that Outer Space has 30 rows instead of 29. Outer Space is the room that comes up when the game finds a room is non-existent, which shouldn't happen with a properly-working game, except in Outside Dimension VVVVVV. In fact, each level file has their own Outer Space, and every single Outer Space also has 30 rooms. So really, this means there are 44 rooms in the Lab and one Outer Space room. (Well, in reality, there are 46 rooms in the Lab, because 2 of them use the Outside tileset but have no room names, so they're stored in Otherlevel.cpp instead.) We find the same result for the Warp Zone. `grep 'push_back' WarpClass.cpp | wc -l` returns 697, which is 24 remainder 1, meaning 23 rooms of 29 rows and 1 room of 30 rows, which corresponds with 23 rooms in the Warp Zone and one Outer Space room. However, Outside Dimension VVVVVV + Tower Hallways and Space Station 1 and 2 are both odd curiosities. Finalclass.cpp contains Outside Dimension VVVVVV, (which is Intermission 1 and 2 and the Final Level), but also the Tower Hallway rooms, i.e. the auxiliary Tower rooms that are not a part of the main tower. Spacestation2.cpp contains both Space Station 1 and 2, so don't be deceived by the name. `grep 'push_back' Finalclass.cpp | wc -l` returns 1597, which is actually 55 remainder 2. So... are there two rooms with 30 rows? Yes, in fact, The Gravitron and Outer Space both contain 30 rows. So there are actually 55 rooms stored in Finalclass.cpp (not including the minitowers Panic Room and The Final Challenge), 54 rooms of actual level data and one Outer Space room, and breaking down the 54 rooms even further, 51 of them are actually in Outside Dimension VVVVVV and 3 of them are Tower Hallways. Of the 51 Outside Dimension VVVVVV rooms, 14 of those are Intermission 1, 4 of them are Intermission 2, and the rest of the 33 rooms are the Final Level (again, not including the minitowers). `grep 'push_back' Spacestation2.cpp | wc -l` returns 2148, which is 74 remainder 2. Are there two rooms with 30 rows again? No; one of those counted 2148 rows is a false-positive, because there's an if-else in Prize for the Reckless that replaces the row with spikes with a row without spikes if you are in a time trial or in No Death Mode. So there's 73 rooms in Space Station 1 and 2, and one Outer Space room. With all this in mind, I decided to duplicate the current last row of each room, the 29th row, to add a 30th row. However, I wasn't going to do this automatically! But neither was I going to write some kludge-y code to parse each nightmare of a level file and duplicate the rows that way. Enter: Vim macros! (Er, well, actually, I use Neovim.) I first did `/push_back`, so that pressing `n` would keep going to the next `push_back` in the file. Then I went to the 29th row of the first room in the file, did a `Yp`, and then started my macro with `qq`. The macro went like this: `30nYp`, which is simply going to the 29th row of the next room over and duplicating it. And that's all there was to it. However, I had to make sure that (1) my cursor was before the `push_back` on the line of the 29th row of the room, and (2) that I didn't skip rooms, both of which were problems I encountered when pressing Ctrl+Z a given invocation of the macro (the Ctrl+Z is just a metaphor, you actually undo by typing `u` in Vim). And also I had to make sure to be careful around the extra lines of `push_back`s in Prize for the Reckless and The Gravitron, and make sure I didn't run past the end of the file and loop back around. Thankfully, all Outer Space rooms are at the end of each file. But first, I had to increase the number of rows drawn in Graphics.cpp by 1 in order to compensate for this, and do the same when reading the tile data in Map.cpp. I had to change fillcontent(), drawmap(), drawfinalmap(), drawtowermap(), and drawtowermap_nobackground(). Funnily enough, the tower functions already used 30 rows, but I guess it's an off-by-one due to the camera scrolling, so they now draw 31 rows each. Then, I went in-game to make sure that the row behind each room name looked fine. I checked EVERY single room with a room name. I turned on invincibility mode and added a temporary line to hardreset() that always turned on game.nocutscenes for a smoother playtesting experience. And to make sure that rooms which have entirely empty bottom rows actually still have 30 rows, instead of having 29 and the game assuming that the 30th row was empty (because that sounds like it could lead to Undefined Behavior), I added this temporary debugging line to the start of mapclass::fillcontent(): printf("(%i,%i) has %i rows\n", game.roomx, game.roomy, (int) tmap.size()); Everywhere I checked - and I made sure to check all rooms - every room had 30 rows and not 29 rows. Unfortunately, some rooms simply couldn't be left alone with their 29th row duplicated and had to be manually edited. This was because the 29th row would contain some edge tiles because the player would be able to walk somewhere on the 28th, 27th, and 26th rows, and if you duplicated said edge tiles behind the room name, it would look bad. Here's a list of rooms whose 30th rows I had to manually edit: - Comms Relay - The Yes Men - Stop and Reflect - They Call Him Flipper - Double-slit Experiment - Square Root - Brought to you by the letter G - The Bernoulli Principle - Purest Unobtainium - I Smell Ozone - Conveying a New Idea - Upstream Downstream - Give Me A V - $eeing Dollar $ign$ - Doing Things The Hard Way - Very Good - Must I Do Everything For You? - Now Stay Close To Me... - ...But Not Too Close - ...Not as I Do - Do Try To Keep Up - Whee Sports - As you like it This is actually a strange case where it looked bad because of the 29th row, instead of the 30th row, and I had to change the 29th row instead of the 30th row to fix it. - Maze With No Entrance - Ascending and Descending - Mind The Gap Same strange case as "As you like it" (it's the 29th row I had to change that was the problem, not the 30th). - 1950 Silverstone Grand V - The Villi People I found that Panic Room and The Final Challenge also looked strange behind the roomname background, but I can't do much about either because towers' tile data wrap around at the top and bottom, and if I added another row to either it would be visible above the room name. I've considered updating the development editors with these new level tiles, but I decided against it as the development editors are already pretty outdated anyway.

Fix default Graphics::setcol() value having no alpha This patch fixes a regression caused by commit 6b1a7ebce6fa77ec54c881bec95081b1a2826646. When you spawn a crewmate with an invalid color, by doing something like `createentity(100,100,18,-1,0)` (here the color is -1, which is invalid), a white crewmate with the color of solid white (255, 255, 255) would appear. That is, until AllyTally came along and committed commit 6b1a7ebce6fa77ec54c881bec95081b1a2826646 (Make "[Press ENTER to return to editor]" fade out after a bit) (PR #158). Then after that commit, it would seem like the crewmate didn't appear, but in reality they were just invisible, because they had an invisible color. As part of Ally's changes, to properly support drawing text with a certain amount of alpha, she made BlitSurfaceColoured() account for the alpha of the color given instead of only caring about the RGB of the color, discarding the alpha, and using the alpha of the surface it was drawing instead. This effectively made it so the alpha of whatever it was drawing would be 255 all the time, except for if you had custom textures and your custom textures had translucent pixels. However, the default color set by Graphics::setcol() if you didn't provide a valid color index was 0xFFFFFF. Which is only (255, 255, 255) but ends up having an alpha value of 0 (because it's actually 0x00FFFFFF). And all colors drawn with alpha 0 end up being drawn with alpha 0 after 6b1a7ebce6fa77ec54c881bec95081b1a2826646. So invalid-colored entities will end up being invisible. To fix this, I just decided to add alpha to the default value instead. In addition, I used getRGB() to be consistent with all the other colors in the function.

Reduce dependency on libc functions During 2.3 development, there's been a gradual shift to using SDL stdlib functions instead of libc functions, but there are still some libc functions (or the same libc function but from the STL) in the code. Well, this patch replaces all the rest of them in one fell swoop. SDL's stdlib can replace most of these, but its SDL_min() and SDL_max() are inadequate - they aren't really functions, they're more like macros with a nasty penchant for double-evaluation. So I just made my own VVV_min() and VVV_max() functions and placed them in Maths.h instead, then replaced all the previous usages of min(), max(), std::min(), std::max(), SDL_min(), and SDL_max() with VVV_min() and VVV_max(). Additionally, there's no SDL_isxdigit(), so I just implemented my own VVV_isxdigit(). SDL has SDL_malloc() and SDL_free(), but they have some refcounting built in to them, so in order to use them with LodePNG, I have to replace the malloc() and free() that LodePNG uses. Which isn't too hard, I did it in a new file called ThirdPartyDeps.c, and LodePNG is now compiled with the LODEPNG_NO_COMPILE_ALLOCATORS definition. Lastly, I also refactored the awful strcpy() and strcat() usages in PLATFORM_migrateSaveData() to use SDL_snprintf() instead. I know save migration is getting axed in 2.4, but it still bothers me to have something like that in the codebase otherwise. Without further ado, here is the full list of functions that the codebase now uses: - SDL_strlcpy() instead of strcpy() - SDL_strlcat() instead of strcat() - SDL_snprintf() instead of sprintf(), strcpy(), or strcat() (see above) - VVV_min() instead of min(), std::min(), or SDL_min() - VVV_max() instead of max(), std::max(), or SDL_max() - VVV_isxdigit() instead of isxdigit() - SDL_strcmp() instead of strcmp() - SDL_strcasecmp() instead of strcasecmp() or Win32 strcmpi() - SDL_strstr() instead of strstr() - SDL_strlen() instead of strlen() - SDL_sscanf() instead of sscanf() - SDL_getenv() instead of getenv() - SDL_malloc() instead of malloc() (replacing in LodePNG as well) - SDL_free() instead of free() (replacing in LodePNG as well)

Fix, for in-GAMEMODE sprites, their colors updating too fast Okay, so the problem here is that Graphics::setcol() is called right before a sprite is drawn in a render function, but render functions are done in deltatime, meaning that the color of a sprite keeps being recalculated every time. This only affects sprites that use fRandom() (the other thing that can dynamically determine a color is help.glow, but that's only updated in the fixed-timestep loop), but is especially noticeable for sprites that flash wildly, like the teleporter, trinket, and elephant. To fix this, we need to make the color be recalculated only in the fixed-timestep loop. However, this means that we MUST store the color of the sprite SOMEWHERE for the delta-timesteps to render it, otherwise the color calculation will just be lost or something. So each entity now has a new attribute, `realcol`, which is the actual raw color used to render the sprite in render functions. This is not to be confused with their `colour` attribute, which is more akin to a color "ID" of sorts, but which isn't an actual color. At the end of gamelogic(), as well as when an entity is first created, the `colour` is given to Graphics::setcol() and then `realcol` gets set to the actual color. Then when it comes time to render the entity, `realcol` gets used instead. Gravitron squares are a somewhat tricky case where there's technically TWO colors for it - one is the actual sprite itself and the other is the indicator. However, usually the indicator and the square aren't both onscreen at the same time, so we can simply switch the realcol between the two as needed. However, we can't use this system for the sprite colors used on the title and map screen, so we'll have to do something else for those.

Fix teleporter sprites sometimes being solid colors This commit fixes a bug that also sometimes occurred in 2.2, where the teleporter sprite would randomly turn into a solid color and just be a solid circle with no detail. Why did this happen? The short answer is an incorrect lower bound when clamping the teleporter sprite index in `Graphics::drawtele()`. The long answer is bad RNG with the teleporter animation code. This commit fixes the short answer, because I do not want to mess with the long answer. So, here is what would happen: the teleporter's `tile` would be 6. The teleporter code decrements its `framedelay` each frame. Then when it reached a `framedelay` of 0, it would call `fRandom()` and essentially ask for a random number between 0 and 6. If the RNG ended up being greater than or equal to 4, then it would set its `walkingframe` to -5. At the end of the routine, the teleporter's `drawframe` ends up being its `tile` plus its `walkingframe`. So having a `walkingframe` of -5 here is fine, because its `tile` is 6. Until it isn't. When its `tile` becomes 2, it still keeps its `walkingframe` around. The code that runs when its `tile` is 2 does have the possibility of completely resetting its `walkingframe` to be in bounds (in bounds after its `tile` is added), but that only runs when its `framedelay` is 0, and in the meantime it'll just use the previous `walkingframe`. So you could have a `walkingframe` of -5, plus a `tile` of 2, which produces a `drawframe` of -3. Then `Graphics::drawtele()` will clamp that to 0, which just means it'll draw the teleporter backing, and the teleporter backing is a simple solid color, so the teleporter will end up being completely and fully solid. To fix this, I just made `Graphics::drawtele()` clamp to 1 on the lower bound, instead of 0. So if it ever gets passed a negative teleporter index, it'll just draw the normal teleporter sprite instead, which is better.
