Misa b944d2d847 Fix editor tool menu inconsistencies 
This patch de-duplicates the tool drawing code a bit in the menu that
gets brought up when you press Space in the level editor, as well as
fixes several bugs related to the fact that the original author(s) of
the code decided to copy-paste everything. (It was most likely Terry,
judging by the distinct lack of whitespace between tokens in the code.)

There are two "pages" of tools that get shown when you open the tool
menu, according to your currently-selected tool.

1. On the first page, your currently-selected tool gets a brighter
   outline. However, on the second page, the code to draw the outline over
   your currently-selected tool is missing. So I've fixed that.

2. On the first page, the glyph indicator next to the tool icon also
   gets brighter when you have that tool selected. However, on the
   second page, the code that drew the brighter-colored indicator got
   ran before the code that drew the normal-colored indicator, so this
   was never shown. This is also fixed.

3. The glyph indicator of the gravity line tool didn't get brighter when
   you had it selected, due to its special-cased copy-pasted code
   drawing its brighter color before drawing its normal color. This has
   also been fixed.

4. Lastly, the tool menu no longer draws the brighter-colored glyphs on
   top of the normal-colored glyphs. Instead, the menu will simply draw
   the brighter-colored glyphs and will not draw the normal-colored
   glyphs in the first place. This is because double-drawing text like
   this will look bad if the user has a custom font.png that has
   translucent pixels, like I do.

All of these bugs have been fixed by paying off the technical debt of
copy-pasting 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
