This fixes all the headaches about map.extrarow having to be the correct value and which way it should be and whatnot. The latest headache was the detection that prevent user-initiated menu animations while an animation was already happening being tripped because graphics.menuoffset would be 230 (due to closing the menu while being in a room without a room name), but then going to a room with a room name would check for 240 instead, and 230 is less than 240. (The numbers are the wrong way round because I got the ternaries the wrong way round, but even if the numbers are the correct way round, the bug would still happen, but it would just be reversed.) So instead, I've just made it 240 for both. This doesn't change the duration of the menu animation (because the animation moves in increments of 25, and 230 / 25 == 240 / 25 under integer division). It might change the animation slightly, but it was already inconsistent anyway because map.extrarow was always set to be 1 in custom levels, and I legitimately would not be able to tell the difference without recording the animations and nitpicking it frame-by-frame. Fixes #841. |

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 2.0.14+ 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 -A Win32 -G "Visual Studio 10 2010" .. -DSDL2_INCLUDE_DIRS="C:\SDL2-2.0.14\include;C:\SDL2_mixer-2.0.4\include" -DSDL2_LIBRARIES="C:\SDL2-2.0.14\lib\x86\SDL2;C:\SDL2-2.0.14\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.
Also note that if you're using a Visual Studio later than 2010, you will need to
change the -G string accordingly; otherwise you will get a weird cryptic
error. Refer to the list below:
- VS 2012:
"Visual Studio 11 2012" - VS 2013:
"Visual Studio 12 2013" - VS 2015:
"Visual Studio 14 2015" - VS 2017:
"Visual Studio 15 2017" - VS 2019:
"Visual Studio 16 2019" - VS 2022:
"Visual Studio 17 2022"
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
