This implementation uses only a single dependency (antlr4-runtime) and avoids usage of reflection and ResourceBundle to allow for cross-compilation to o ther platforms. Though made for video games, it is possible to use it any Java-based application. The parser is implemented as an ANTLR grammar so it is also possible to compile it to other languages.
