GRILL DIS adds in Distributed Interactive Simulation (DIS) support for Unity through utilizing Open-DIS libraries.The GRILL DIS plugin allows users to set up custom DIS entities through custom objects provided by the plugin. It also provides basic User Datagram Protocol (UDP) socket support and handles interpreting of DIS network traffic using Open-DIS libraries. The plugin uses the interpreted DIS data to create and update user specified DIS entities in Unity. The DIS plugin provides an interface for a user to add on custom functionality when specific DIS data is received. The plugin also supports sending DIS information through utilizing the Open-DIS libraries allowing DIS data to be sent out of Unity to other DIS-capable simulations.Core components of the GRILL DIS plugin are decoupled to allow for custom functionality to easily be added. If custom UDP socket support, Protocol Data Unit (PDU) processing, or managing of DIS entities are desired, the basic, supplied components can easily be replaced by new components. Furthermore, the GRILL DIS plugin is not tied down to a specific round earth model. The plugin provides its own geospatial conversion functions for conversions between ECEF, LLA, Unity Flat Earth coordinates, and Unity Round Earth coordinates.The GRILL DIS plugin currently has base functionality for a select few DIS PDUs.

Community contributions to expanding the plugin are encouraged and greatly appreciated.This is GRILL DIS v0.4.1, published 2022-12-14. See the changelog to see what changed in each version.Features:UDP Sender/ReceiverPDU ProcessorDIS Game ManagerEvents to handle DIS updatesDIS Game Object ComponentsDIS InterfaceFull C# Source code includedSupported Development Platforms: Win64Supported Target Build Platforms: Win64Additional Notes:There will be potential loss of floating point data due to only 32-bit floating point support in the editor. Due to this, values are truncated at the last moment possible internally to be as accurate as possible.The example project does NOT come with DIS playback scenarios. It shows usage of the DIS plugin and supplies models for various DIS entities. The user will need to generate their own DIS network traffic. One way this can be done is by spinning up two instances of the example project, one for sending and one for receiving.
