SgCity

Tile based 3D city builder maked from scratch with OpenGL.

Current Features

• Runs on Windows and Linux
• A fixed time step game loop which process input events, update and render game objects
• Logging, Exceptions, Assertions
• OpenGL renderer
• Event system
• ImGui based menus
• Configurable with a config.ini
• A skybox for a nice background
• A camera that allows us to move freely
• Terrain manipulation (raise and lower)
• Tile selection
• Different tiles for residential, commercial, industrial and traffic zones
• The game determines if zones are connected, e.g. with a road.
• A road network can be built.
• Animated water surfaces
• Loads 3D models made in Blender (so we can load plants, trees, buildings etc.)

Next

• Select buildings via menu
• Align game objects to the grid and highlights the tiles in color
• A complete city with simple gameplay
• Heightmap based terrain creation
• Load and save the city

Build instructions

Win

First, install the Conan package manager locally.

As this project relies on multiple 3rd-Party Libs, I created a conanfile.txt with all the requirements.

[requires]
glfw/3.3.5
glew/2.2.0
glm/0.9.9.8
spdlog/1.9.2
imgui/1.86
assimp/5.1.0

[generators]
premake

My favor build configuration tool for Windows is Premake5. Premake5 can generate Makefiles and Visual Studio Solutions with a single description file for cross-platform projects. Download Premake5 to your preferred location.

Complete the installation of requirements for the project running:

$ conan install conanfile_win.txt -s build_type=Debug

or

$ conan install conanfile_win.txt -s build_type=Release

followed by:

$ premake5 vs2019

Linux

First, install the Conan package manager locally.

If you are using GCC compiler >= 5.1, Conan will set the compiler.libcxx to the old ABI for backwards compatibility. You can change this with the following commands:

$ conan profile new default --detect  # Generates default profile detecting GCC and sets old ABI
$ conan profile update settings.compiler.libcxx=libstdc++11 default  # Sets libcxx to C++11 ABI

As this project relies on multiple 3rd-Party Libs, I created a conanfile.txt with all the requirements.

[requires]
glfw/3.3.5
glew/2.2.0
glm/0.9.9.8
spdlog/1.9.2
imgui/1.86
assimp/5.1.0

[generators]
cmake

Complete the installation of requirements for the project running:

$ conan install conanfile.txt -s build_type=Debug --build missing

or

$ conan install conanfile.txt -s build_type=Release --build missing

If the following error occurs: ERROR: opengl/system: Error in package_info() method, line 80, then pkg-config must be installed first.

$ mkdir build
$ cd build
$ cmake ..
$ make
$ cd src/bin
$ ./SgCity
