Marble Marcher: Community Edition

Version 1.4.5

Logo

This is the community edition of Marble Marcher, a procedurally rendered fractal physics marble game in which you must get to the flag in each level as fast as you can. With 24 levels to unlock and an active speedrunning community, along with a fully-featured level editor, there's always new features being developed. If you complete all levels, you can use cheats to create and enhance a more exploratory experience.

Because version 1.1.0 was the last feature update of Marble Marcher, we (the Marble Marcher Community) opted to create a community edition to keep the community around the game alive and continuously improve the experience. Currently this is maintained mainly by members of the Marble Marcher Community on Discord, in addition to the members of the subreddit and anyone else who has contributed.

Marble Marcher: Community Edition comes with a wealth of new features and improvements, including performance improvements and graphical enhancements.

If you have suggestions, issues, or would like to contribute, feel free to submit issues and pull requests. After all, this is a community project!

Note: This project requires a mid-range dedicated graphics card (non-integrated) to run in HD (1920x1080) at a good FPS. Anything higher and you'll likely need a higher-range card. However, if no HD isn't an issue, you can lower the resolution or settings to run on something like a laptop or budget computer, in which case the game will run just fine.

Original Summary

Marble Marcher is a video game demo that uses a fractal physics engine and fully procedural rendering to produce beautiful and unique gameplay unlike anything you've seen before.

The goal of the game is to reach the flag as quickly as possible. But be careful not to fall off the level or get crushed by the fractal! There are 24 levels to unlock.

Proposed Changes

Though Marble Marcher CE is a largely finished game, there are still several improvements we'd like to implement. Here are our proposed changes:

  • ### Fixes
    • Make sure game runs at the same speed everywhere
    • Mouse/camera speed is too fast while skipping cutscenes
  • ### User Experience Improvements
    • Pre-built versions for the common operating systems and make them available as GitHub releases (in progress)
    • Make the fractal recoloring from cheats persistent
    • More efficient anti-aliasing modes
    • Toggle to always activate fast cutscenes
    • Better autosplitter integration
  • ### New Features
    • Cheat: no drag
    • Custom marble designs
    • Add a script to build for all platforms at once
    • Have MarbleMarcher added to package managers
  • ### Currently WIP
    • Recording/replay functionality
    • Debug info screen
    • Cheat: unlock all levels
    • Add creation of macOS
      .dmg
      for easy distribution.

System Dependencies

MacOS

On macOS these can be conveniently installed using HomeBrew:

brew install cmake eigen sfml anttweakbar glew glm

The version of SFML required is 2.5.1 or newer. It has come to my attention that HomeBrew does now have this version (unlike when these instructions where first written) so installing via HomeBrew should work but you can still download manually if you wish and install using these instructions. You must install the Frameworks option not the dylib option or the build script may fail. Note that if HomeBrew installed a version of SFML older than 2.5.1 for some reason or you wish to install manually, you must remove the version of SFML that Brew installed using

brew remove sfml
.

Alternatively, vcpkg can be used though it is unsupported:

vcpkg install cmake eigen3 sfml anttweakbar

It may also be possible to use MacPorts which is also unsupported and untested.

Arch Linux

The packages

eigen
,
sfml
,
glm
,
git
,
cmake
and
make
are on the core, extra and community repositories.
sudo pacman -S eigen sfml glm git cmake make
However,
anttweakbar
is on the AUR. Clone and build it yourself, or use and AUR Helper like yay :
yay -S anttweakbar

Building

MacOS

Build Script

Note for the current version: the macOS build is not yet entirely working properly so revert to the previous prerelease as required. SFML is properly included but as of yet, AntTweakBar is not so this executable will not work on machines without it installed. Simply run

./macOSBuildExec.sh
( You can alternatively use macOSBuildBundle which is the old version of the script, which will generate a full .app file instead of a normal unix executable). This will generate the MarbleMarcher executable that can be used like any other application. It can even be used on systems without SFML as SFML is included in the bundle and the binary is relinked to these versions (As stated above it currently does not work on systems without AntTweakBar installed). Currently the script will only do the relinking part properly if you use SFML 2.5.1 specifically however it is planned to allow for any version. If you have another version, the script will still work, the app just won't work on a machine without SFML.

Manual

Due to macOS being unable to find GLMINCLUDEDIR it is now assumed to be ./glm . In order for this method to work, GLM should now be manually installed into that directory. *

wget https://github.com/g-truc/glm/releases/download/0.9.9.8/glm-0.9.9.8.zip
*
unzip ./glm-0.9.9.8.zip
*
mkdir build && cd build
*
cmake ..
*
cmake -DCMAKE_CXX_FLAGS="-I/usr/local/include" ..
* If you use
vcpkg
, add the flag
-DCMAKE_TOOLCHAIN_FILE=[path/to/vcpkg]/scripts/buildsystems/vcpkg.cmake
*
cd ..
*
cmake --build build

Note that this just builds a binary and not an Application bundle like you might be used to seeing. To run properly, you must move the binary (which, after building, is

build/MarbleMarcher
). It is not recommended to build the Application bundle manually so no instructions for that are provided however you may peek in
macOSBuildBundle.sh
to see how it is done.

Alternatively, one can use the platform-dependent build system, for example

Make
:
  • make -C build

Arch Linux

  • cd ~
  • git clone https://github.com/WAUthethird/Marble-Marcher-Community-Edition.git
  • cd Marble-Marcher-Community-Edition
  • mkdir build && cd build
  • cmake ..
  • cd ..
  • cmake --build build
  • cp build/MarbleMarcher ./

Alternatively, you can install the AUR package at marblemarcher-git using your preferred AUR Helper. *

yay -S marblemarcher-git

Ubuntu

The main problem with the installation is the dependency AntTweakBar, a C++ library with no Ubuntu package.

But the first and easy step is to ensure that the following development tools and libraries are installed:

libsfml-dev
,
libglm-dev
,
libeigen3-dev
,
libglew-dev
,
cmake
,
libglu1-mesa-dev
and
mesa-common-dev
. You can get it done with
sudo apt-get install libsfml-dev libglm-dev libeigen3-dev \
     libglew-dev cmake libglu1-mesa-dev mesa-common-dev
You may need to install more (or fewer) libraries, depending on what do you already have on your system.

How to Install on Ubuntu 20.04

The first step is to download and install AntTweakBar library. I assume you have unpacked it into Downloads folder. The installation is as easy as running

make
in
AntTweakBar/src
folder. As a result, make should create
libAntTweakBar.a
and
libAntTweakBar.so
in your
AntTweakBar/lib
folder. You may want to move those to a better location, e.g. into
$HOME/lib
.

This installation can be done with commands

cd ~/Downloads/AntTweakBar/src
make

The next task is to clone (or download) Marble Marcher. In the following examples we assume you have downloaded Marble Marcher into Downloads-folder as well. First you create an empty folder build in the Marble Marcher folder, and run cmake from there. However, and this is important, for the following compilation step you also have to specify the location of

AntTweakBar.h
and
libAntTweakBar.a
files using the
CPATH
and
LIBRARY_PATH
environment variables. You can do all these steps as follows:
cd ~/Downloads
git clone https://github.com/WAUthethird/Marble-Marcher-Community-Edition.git
cd Marble-Marcher-Community-Edition
mkdir build
cd build
cmake ..
CPATH="$HOME/Downloads/AntTweakBar/include/" LIBRARY_PATH="$HOME/Downloads/AntTweakBar/lib" cmake --build .
This should create an executable file
MarbleMarcher
in the current
src
folder.

The executable needs

libAntTweakBar.so
run-time library for running. So when executing it, you have to tell it where the library is by using
LD_LIBRARY_PATH
environment variable. Hence you run the game as
LD_LIBRARY_PATH="$HOME/Downloads/AntTweakBar/lib" ./MarbleMarcher
Consider moving
libAntTweakBar.so
into a dedicated location for run-time libraries and configuring your
LD_LIBRARY_PATH
.

Enjoy!

Installing on Ubuntu 18.04

Compiling on Ubuntu 18.04 works mostly in the same way as on Ubuntu 20.04. However, the default gcc 7.5.0 is too old for the source code. You have to use gcc 8.4.0, provided in the package gcc-8. First, install all the packages required for Ubuntu 20.04. Thereafter also install gcc-8:

sudo apt-get install libsfml-dev libglm-dev libeigen3-dev \
     libglew-dev cmake libglu1-mesa-dev mesa-common-dev
sudo apt-get install gcc-8
Next, as the default gcc is still version 7, we have to tell make and cmake explicitly that we we want gcc 8 instead.

Open

AntTweakBar/src/Makefile
in a text editor (e.g. gedit), and set the make variables
CXX
and
LINK
(see lines 18 and 21) to
gcc-8
and
g++-8
.
So the relevant lines should look like
CXX         = gcc-8
CXXFLAGS    = $(CXXCFG) -Wall -fPIC -fno-strict-aliasing -D_UNIX -D__PLACEMENT_NEW_INLINE
INCPATH     = -I../include -I/usr/local/include -I/usr/X11R6/include -I/usr/include
LINK        = g++-8
Now run
make
in the src-folder as in case of Ubuntu 20.04:
cd AntTweakBar/src
make

Cloning Marble Marcher on Ubuntu 18.04 works exactly as on Ubuntu 20.04. But now, when creating cmake environment, we tell cmake that we use gcc-8 by setting

CC
and
CXX
environment variables. Otherwise we follow exactly the steps for Ubuntu 20.04. So on 18.04 you can do
cd ~/Downloads
git clone https://github.com/WAUthethird/Marble-Marcher-Community-Edition.git
cd Marble-Marcher-Community-Edition
mkdir build
cd build             
CC=/usr/bin/gcc-8 CXX=/usr/bin/g++-8 cmake ..
CPATH="$HOME/Downloads/AntTweakBar/include/" LIBRARY_PATH="$HOME/Downloads/AntTweakBar/lib" cmake --build .
As above, your should see the executable MarbleMarcher that can be started with
LD_LIBRARY_PATH="$HOME/Downloads/AntTweakBar/lib" ./MarbleMarcher

Compiling on Windows

Windows compilation should work just fine now. It's relatively easy to do without help, but in case you'd like them, here are some configuring and compiling instructions.

Cross-Compile for Windows on macOS

This requires you to install wget, mingw-w64, and git (which you probably already have) either with HomeBrew (recommended) or otherwise. Theoretically, you should be able to just run

winMacOSBuild.sh
. There are no manual instructions because due to issues I had to just compile the thing manually which is annoying and has too many steps.

Launching

macOS

If the macOS build script was used, simply launch the app as normal, otherwise: * Make sure that the current working directory contains the

assets
folder * Run the executable generated by CMake, located in
build
(or a subdirectory) * If running MarbleMarcher from a tarball and you see a message like

./MarbleMarcher: error while loading shared libraries: libsfml-graphics.so.2.5: cannot open shared object file: No such file or directory You'll just need to run MarbleMarcher with the correct

LD_LIBRARY_PATH
:
LD_LIBRARY_PATH=`pwd`/usr/lib ./MarbleMarcher

Windows/Linux/Anything Else

Launching should be self-explanatory for these systems, just run the excecutable file relevant to your system that is generated by the build process.

Troubleshooting/FAQ

  • Why am I getting compute shader compilation errors?
    • If you are running a release binary fully tested by us to be functional, such as those found in the Releases tab, it is most likely a graphics card or driver issue. Try updating your graphics drivers, and if that doesn't fix the problem, take a look at the card itself. If you are a Radeon user, compute shaders are either unsupported or not fully supported on cards before the HD 7000 series. If this is the case, you will need to upgrade if you would like to play the game. Otherwise, if you compiled it yourself, whether by our official instructions or for a non-supported operating system, please open an issue and post the error logs.
