    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

This plugin allows you to hook your UE4 project with a running Holochain Conductor App-Interface over a valid WebSocket address.

It defines u-interfaces for the abstraction of Holochain-specifics: IHolochainAgent and IHolochainZome, which your project must implement.

The Request and Response u-classes for the Holochain zome-calls must implement the IHolochainInputOutput Interface defined in the plugin.

Additionally, it also exposes MessagePack to your project (statically), along with some handy debugging for MsgPack encrypted messages via a simple FMessagePackObject wrapper class.

Further documentation here.

Last tested with Holochain 0.0.100.
