Ekosystem

Ekosystem is a C++ 3D "game" focused around simulating a simple data-driven ecosystem of animals.

It is built using suprengine, my custom engine which uses OpenGL and SDL2.

Dependencies

Project

• C++20 compiler
• OpenGL 3.3.0
• CMake 3.11

Libraries

• cpp-suprengine

Features

• A complete user interface tool using ImGui for game development, both system balancing and debug
• TODO

Project Structure

This project only holds the engine code since it is de-coupled from games code.

Folder structure:

• assets/ contains game assets, such as data defining pawns, curves, etc.
• src/ contains source files of the game.

Build the project

This project is built using CMake 3.11, ensure you have already installed a compatible version.

Steps

0. Create a folder anywhere for the installation, we'll name it ekosystem. The reason for this is that the game's CMakeLists.txt will attempt to finds the engine's folder directly from its own parent folder, if you don't want that, look at the Troubleshooting section.
1. Clone the engine's repository in ekosystem/cpp-suprengine.
2. Run command git submodule update --init in the engine's folder.
3. Clone the game's repository (this one) in ekosystem/cpp-ekosystem.
4. Run the game's CMakeLists.txt either by using CMake's command line interpreter, CMake's GUI or your favorite IDE.

Troubleshooting

Change engine's folder location

If for some reasons you want to move the engine's or game's folder apart from each other, you can configure the location of the engine using the CMake variable SUPRENGINE_PATH.

Using command line:

cd build
cmake .. -DSUPRENGINE_PATH=C:/Path/To/Engine/

You can also use cmake-gui to change this variable.

Couldn't update engine's Git Submodules

If running the git submodule update command didn't work for any reasons, replace the folder libs/curve-x by cloning arkaht/cpp-curve-x.

Need administrator privileges to run the CMakeLists.txt
