This bug is technically NOT a regression - the code responsible for it has been around since the source release. However, it hasn't been a problem until Graphic Options and Game Options were added to the pause screen. Since then, if you opened the pause menu in Flip Mode, pressing up would move to the menu option below, and pressing down would move to the menu option above. Notably, left and right still remain the same. This is because the map screen input code assumes that the menu options will be flipped around - however, this has never been the case. What happens instead is that the menu options get flipped around time when in Flip Mode - flipping what's already flipped - so it ends up the same again. (Incidentally enough, the up/down reversing code is present on the title screen, and is correct - if you happen to set graphics.flipmode to true on the title screen, the title screen doesn't negate the flipped menu options, so pressing up SHOULD be treated like pressing down, and vice versa. However, in 2.3, it's not really possible to set graphics.flipmode to true on the title screen without using GDB or modifying the game. In 2.2 and previous, you can just complete the game in Flip Mode, and the variable won't be reset; 2.3 cleaned up all exit paths to the menu to make sure everything got reset.) This isn't a problem when there's only two options, but since 2.3 adds two more options to the pause screen, it's pretty noticeable. Anyway, this is fixed by simply removing the branch of the graphics.flipmode if-else in mapinput(). The 'else' branch is now the code that gets executed unconditionally. Don't get confused by the diff; I decided to unindent in the same commit because it's not that many lines of code. |

How to Build
VVVVVV's official desktop versions are built with the following environments:
- Windows: Visual Studio 2010
- macOS: Xcode CLT, currently targeting 10.9 SDK
- GNU/Linux: CentOS 7
The engine depends solely on SDL2 and SDL2_mixer. All other dependencies are statically linked into the engine. The development libraries for Windows can be downloaded from their respective websites, Linux developers can find the dev libraries from their respective repositories, and macOS developers should compile and install from source (including libogg/libvorbis/libvorbisfile).
Steamworks support is included and the DLL is loaded dynamically, you do not need the SDK headers and there is no special Steam or non-Steam version. The current implementation has been tested with Steamworks SDK v1.46.
To generate the projects on Windows:
# Put your SDL2/SDL2_mixer folders somewhere nice!
mkdir flibitBuild
cd flibitBuild
cmake -G "Visual Studio 10 2010" .. -DSDL2_INCLUDE_DIRS="C:\SDL2-2.0.10\include;C:\SDL2_mixer-2.0.4\include" -DSDL2_LIBRARIES="C:\SDL2-2.0.10\lib\x86\SDL2;C:\SDL2-2.0.10\lib\x86\SDL2main;C:\SDL2_mixer-2.0.4\lib\x86\SDL2_mixer"
Note that on some systems, the SDL2_LIBRARIES list on Windows may need
SDL2/SDL2main/SDL2_mixer to have .lib at the end of them. The reason for this
inconsistency is unknown.
To generate everywhere else:
mkdir flibitBuild
cd flibitBuild
cmake ..
macOS may be fussy about the SDK version. How to fix this is up to the whims of however Apple wants to make CMAKE_OSX_SYSROOT annoying to configure and retain each time Xcode updates.
Including data.zip
You'll need the data.zip file from VVVVVV to actually run the game! It's available to download separately for free in the Make and Play edition of the game. Put this file next to your executable and the game should run.
This is intended for personal use only - our license doesn't allow you to actually distribute this data.zip file with your own forks without getting permission from us first. See LICENSE.md for more details. (If you've got a project in mind that requires distributing this file, get in touch!)
A Word About Compiler Quirks
(Note: This section only applies to version 2.2 of the source code, which is the initial commit of this repository. Since then, much hard work has been put in to fix many undefined behaviors. If you're compiling the latest version of the source code, ignore this section.)
This engine is super fussy about optimization levels and runtime checks. In particular, the Windows version absolutely positively must be compiled in Debug mode, with /RTC enabled. If you build in Release mode, or have /RTC disabled, the game behaves dramatically different in ways that were never fully documented (bizarre softlocks, out-of-bounds issues that don't show up in tools like Valgrind, stuff like that). There are lots of things about this old code that could be cleaned up, polished, rewritten, and so on, but this is the one that will probably bite you the hardest when setting up your own build, regardless of platform.
We hope you'll enjoy messing with the source anyway!
Love, flibit
