Previously, the game would not store the size of the window itself, and would always call SDL_GetRendererOutputSize() (via Screen::GetWindowSize()) to figure out the size of the window. The only problem is, this would return the size of the whole monitor if the game was in fullscreen mode. And the only place where the original windowed mode size was stored would be in SDL itself, but that wouldn't persist after the game was closed. So, if you exited the game while in fullscreen mode, then your window size would get set to the size of your monitor (1920 by 1080 in my case). Then when you opened the game and toggled fullscreen off, it would go back to the default window size, which is 640 by 480. This is made worse, however, if you were in forced fullscreen mode when you previously exited the game in windowed mode. In that case, the game saves the size of 1920 by 1080, but doesn't save that you were in fullscreen mode, so opening the game not in forced fullscreen mode would result in you having a 1920 by 1080 window, but in windowed mode. Meaning that not even fullscreening and unfullscreening would put the game window back to normal size. The solution, of course, is to just store the window size ourselves, like any other screen setting, and only use GetWindowSize() if needed. And just to make things clear, I've also renamed the GetWindowSize() function to GetScreenSize(), because if it was named "window" it could lead one to think that it would always return the size of the screen in windowed mode, when in fact it returns the size of the screen whatever mode it is in - fullscreen size if in fullscreen mode and window size if in windowed mode. And doing this also fixes the FIXME above Screen::isForcedFullscreen(). |

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 2.24.0+. All other dependencies are statically linked into the engine. The development libraries for Windows can be downloaded from SDL's website, Linux developers can find the dev libraries from their respective repositories, and macOS developers should compile and install from source. (If you're on Ubuntu and your Ubuntu is too old to have this SDL version, then see here for workarounds.)
Since VVVVVV 2.4, git submodules are used for the
third party libraries.
After cloning, run git submodule update --init
to set all of these up.
You can also use this command whenever the submodules need to be updated.
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 folders somewhere nice!
mkdir flibitBuild
cd flibitBuild
cmake -A Win32 -G "Visual Studio 10 2010" .. -DSDL2_INCLUDE_DIRS="C:\SDL2-2.24.0\include" -DSDL2_LIBRARIES="C:\SDL2-2.24.0\lib\x86\SDL2;C:\SDL2-2.24.0\lib\x86\SDL2main"
Note that on some systems, the SDL2_LIBRARIES
list on Windows may need
SDL2/SDL2main 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
