JSON serializer adapted for use in Magma framework for Rust game
// :: In Rust We Trust :: Plugin Dev server for Magma :: net.connect 23.239.114.234:28025 ::
// JSON serializer adapted from https://github.com/douglascrockford/JSON-js 2014-02-04 Public Domain.
// Adapted by mikec @ gomagma.org forum. Steam Group: http://steamcommunity.com/groups/MCIRWT
// Use: var jsonstring = IRWTJSON.stringify(obj); var obj = IRWTJSON.parse(jsonstring);
// Copy this code to the top of any plugin running on your system. All plugins can use it.
// You can even put it in a plugin by itself, with no hooks or other code.
