University Technical Institute, Semester 2 - OOP Project : Auto-scrolling runner game

Description

Boko Runner is a C++ OOP project done as part of our DUT second semester's programming project. It consisted in creating a "runner" game (an auto-scrolling platform game) where the player has to dodge each obstacle and collect bonuses to increase its score. The game ends when the player's life bar is empty. The project allowed us to put into practice the Object Oriented Programming notions that we learnt in S2.

Initially made to be based on a Model-View architecture as requested, the project can be considered as a Multi-Tier Architecture with a persistence manager, an app core, models, and views.

This academic project was initially conducted for 4 months (February - May 2016). Over the following months and years, some features and "under the hood" improvements were brought for different purposes (trying new patterns or practises seen in University, maintaining C++ skills, attempting to extract an SFML UI library, updating dependencies and broken infrastructure). Nowadays, the project is mostly dead. But commits can still come from time to time.

How to build

Libraries requirements

The direct dependencies of the project are fetched using CMake 11+'s FetchContent.
However, you need to manually install SFML's dependencies following the instructions below:

GNU/Linux

Please first install a compatible compiler (GCC 4.9+/Clang-6+) and CMake 11+.
Installing CMake on Linux can be tricky due to some popular distributions still using old CMake versions.
I recommend directly getting CMake from the official website and adding it to the PATH like below:

wget -qO- "https://cmake.org/files/v3.17/cmake-3.17.0-Linux-x86_64.tar.gz" | tar --strip-components=1 -xz -C ~/.local
export PATH=~/local/bin:$PATH

Then, you thought installing CMake was a pain, obtaining all dependencies of SFML on first try is worse.
Installing libsfml-dev and hoping all its dependencies would be installed along is vain.
To help you, here are the steps that worked for me in my attempt to make Travis-CI work for Trusty, Xenial and Bionic:

sudo apt-get update -qq
sudo apt-get install -y libxrandr-dev libx11-dev libopenal-dev libalut-dev libvorbis-dev libogg-dev libflac-dev libxcb-image0 libudev-dev libgl1-mesa-dev libegl1-mesa-dev
sudo apt install --reinstall libudev1

Windows

You need to put some shared libraries (.dll) in C:\Windows\System32 or in the same folder as the executable:

• OpenAL32.dll
• sfml-graphics-2.dll or sfml-graphics-d-2.dll
• sfml-window-2.dll or sfml-window-d-2.dll
• sfml-audio-2.dll or sfml-audio-d-2.dll
• sfml-system-2.dll or sfml-system-d-2.dll

Regarding the compiler to pick, I recommend mingw-w64, as it's the one I use for this project.

MacOS

Per tests previously done with Travis CI on MacOS 10.13 and 10.14, it appears installing XCode is all you need.
I have been able to make everything working on a 2018 Macbook Pro (Catalina) with AppleClang 11 with no changes.

Building steps

GNU/Linux

Execute build.sh file or do, from project folder :

mkdir build
cd build
cmake .. && make

Notes:

• To accelerate building time, you should set the number of cores to use accordingly to your CPU specs.
• When configuring project with CMake, you can select different options, please refer to the main CmakeLists.txt file.

Windows

Unless you want to be enrolled in a complex process to get the project to eventually run, I would strongly recommend you to open the project in a CMake compatible IDE (e.g. QTCreator, CLion). It can analyze the CMake configuration and auto-configure actions to build available binaries.

How to run

GNU/Linux

The available executables are bokorunner and unit_tests.
You just have to launch them like you would do with other unix executables:

$ ./$PATH_TO_EXEC/$EXEC_NAME

Windows

The available executables are bokorunner.exe and unit_tests.exe.
You first have to correctly set the current working directory on your IDE (Run>Edit configurations... for Clion) :

• For bokorunner.exe, it must be ${PROJECT_DIR}/${CMAKE_BUILD_DIR}
• For unit_tests.exe, it must be ${PROJECT_DIR}/${CMAKE_BUILD_DIR}/src

Then you can launch them with the built-in run option.
