libxayagame
is a C++ library that makes it easy to implement games on the
Xaya platform. It takes care of the interaction with
the Xaya Core daemon, so that game developers only have to implement the
rules of their game.
mover
is a simple game using this library, where players
can move around an infinite plane. It is fully functional, although mainly
meant as example and/or basis for more complex games.
Similarly, nonfungible
is a simple implementation
of non-fungible assets on the Xaya platform. It is useful as another example
(of using the
SQLite integration),
for testing Democrit but also as an actual
application on Xaya for issuing and trading fungible and non-fungible tokens.
This repository also contains a framework for game channels as well as Xayaships, which is an example game for channels.
To build libxayagame
and the example mover game, use the standard routine
for building autotools-based software:
autogen.sh && ./configure && make
After a successful build, you can optionally run make check
and/or
make install
to run tests and install the library and moverd
on
your system, respectively.
libxayagame
has a couple of dependencies which need to be installed
for the configuration and/or build to be successful:
libjsoncpp
: The Debian packagelibjsoncpp-dev
can be used.jsonrpccpp
: For Debian, the packageslibjsonrpccpp-dev
andlibjsonrpccpp-tools
are not fresh enough. They need to be built from source; in particular, it must be a version that includes the commit4f24acaf4c6737cd07d40a02edad0a56147e0713
.ZeroMQ
with C++ bindings: Core ZeroMQ is available in the Debian packagelibzmq3-dev
. The C++ bindings need to be installed from the source repository, as the version in the Debian package (at least for Debain 10 "Buster") is too old.zlib
: Available in Debian aszlib1g-dev
.- SQLite3 with the
session extension.
In Debian, the
libsqlite3-dev
package can be installed. Alternatively, build from source and configure with--enable-session
. - LMDB: Available for Debian in the
liblmdb-dev
package. glog
: Available for Debian aslibgoogle-glog-dev
.gflags
: The package (libgflags-dev
) included with Debian can be used.- Protocol buffers
are used both in C++ and Python. On Debian, the packages
libprotobuf-dev
,protobuf-compiler
andpython-protobuf
can be used. eth-utils
, which itself depends onlibsecp256k1
. The latter is available on Debian aslibsecp256k1-dev
.
For the unit tests, also the Google test framework is needed. The package included with Debian 10 "Buster" is not fresh enough, it should be built and installed from source instead.
For running the integration tests based on Python, install Python3 and
the jsonrpclib library. On Debian,
this is python3-jsonrpclib-pelix
.
We also provide a Dockerfile, which can be used to build an image based on Debian that has all dependencies and libxayagame itself prebuilt and installed. (Hint: The file can also just serve as documentation for how to get all dependencies and build libxayagame yourself on a Debian system.)
Builds of this image are also published on Docker Hub.
