Misa 593641ce82 Always destroy and create new player in startgamemode
This fixes a bug where players could flip in mid-air at the start of
custom levels whose start points were in mid-air, because
onground/onroof were not being reset. This could also be done when
loading in to a save with a checkpoint in mid-air. All that's required
is to exit the game while standing on a surface (or otherwise having a
nonzero onground/onroof).

This reminded me that there were other variables on the player entity
persisting through that made loading in to a level not have a totally
clean slate, such as walkingframe (which could affect sequencing
individual TASes together into one TAS), so it's better to just destroy
the player entity and recreate it.

Except some attributes still have to be persisted for 2.2 and 2.0
glitchrunner mode. But it's better that this is done via a whitelist
rather than a blacklist.

The player duplicate removal code in hardreset is mostly redundant now
(except for some very unlikely corner cases), but there's nothing wrong
with having redundant code as long as it's not harmful. I had a
paragraph here justifying why it could be removed but decided it was
simpler to just keep it.

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
