+MV3500 - Internetwork Communications and Simulation
+Prof. Dr. Don Brutzman
+
+Landas, Enrico
+Tacket, Cody
+Yamashita de Moura, Douglas
+
+Final Project
+Adapt a Unity or Other Program to Emit PDUs Using Open-DIS C# Binding
+
+Two C# scripts, Sender.cs and Receiver.cs, were created to send and receive
+PDUs, respectively. The following data is included:
+
+Sender.cs
+- IP Address: 239.1.2.3
+- Port: 3000
+- EntityID.Entity: 1
+
+Receiver.cs
+- IP Address: 239.1.2.3
+- Port: 3000
+- EntityID.Entity to be processed: anyone different from 1
+
+For the project purpose, the scripts were implemented in such a way that all
+multicast information is enclosed on the scripts and only selected information
+is processed and printed on the screen. Each computer will print the data
+from the entity that is different from the one it is sending.
+
+Unity Project
+- The Unity package can be downloaded from:
+- https://owncloud.nps.edu/owncloud/index.php/s/mewLa2BUEWhucPa
+
+Video
+- A video showing two applications working can be found at the Video folder
+of the Unity package
+
+TO-DO List
+- Create an Unity interface to receive input data: IP address, port, etc
+- Transform the object location to real world location (using latitude,
+longitude and altitude)
+- Replace the 'InvokeRepeating' method using a thread (when creating a sender
+and a client on the same computer, this method may not work properly, i.e.,
+the interval between the calls could be different from the expected)
+- Implement creation of the received object on the Receiver.cs (or other
+interface to be created)
+- Implement control of the object (NavySeal guy) using keyboard/mouse
