Cryptovoxels is a voxel-based world built on top of the ethereum blockchain. This scripting engine is for adding interactivity to your Cryptovoxel parcels.
Scripts are written in world using the HTML editing UI ?ui=html, and
run in a webworker on the domain untrusted.cryptovoxels.com. Your
scripts are run in the browser so there is no consistency between
users, they each run their own version of the scripts. This will be
fixed in the future.
This used to be the engine for the websocket / node.js based scripting engine. This may return in the future, but for now, that engine is deprecated.
