openc2e

openc2e is an open-source game engine intended to run all the games in the Creatures series.

Games

openc2e is intended to support:

• Creatures (1996)
• Creatures 2 (1998)
• Creatures 3 (1999)
• Docking Station (2001)
• Creatures Playground (1999)
• Creatures Adventures (2000)

Status

Working

• Agents (COBs) work
• Imperfect physics
• Creatures biochemistry
• Sound effects

Todo

• Actual creatures (C3+ creatures work somewhat, C1 and C2 ones don't work at all)
• Physics improvements (Especially C3+)
• Network ability (the Docking Station warp)
• Serialization (world saving, creature exporting, ...)
• Music

There are lots of open issues that still need solving.

Building

Dependencies

openc2e depends on:

• SDL2
  • SDL2_gfx
  • SDL2_mixer
  • SDL2_net
  • SDL2_ttf
• bison
• re2c
• Python
• Qt5
• CMake
• Boost.Serialization (optional)

Linux

On Ubuntu 18.10 you'll need these packages:

sudo apt-get install \
  build-essential \
  qtbase5-dev \
  libsdl2-dev \
  libsdl2-gfx-dev \
  libsdl2-mixer-dev \
  libsdl2-net-dev \
  libsdl2-ttf-dev \
  re2c

macOS

Install dependencies using Homebrew:

brew install cmake qt

Windows

Install Qt, Python, and Visual Studio's C++ CMake Tools for Windows.

Open the folder in Visual Studio and it will automatically run CMake and set up the build system.

Compiling

Create a new build directory and compile:

cmake -B build .
make -C build openc2e -j4

Running

You need to provide openc2e with the path to the game's data, for example:

./build/openc2e -d /path/to/Creatures2
