// Create a new MemoryStream MemoryStream stream = new MemoryStream(); // Write a Vector3 object to the stream Vector3 vector = new Vector3(1, 2, 3); stream.WriteVector3(vector); // Rewind the stream stream.Rewind(); // Read the Vector3 object from the stream Vector3 newVector = stream.ReadVector3(); // Print the values of the new Vector3 Console.WriteLine("X: " + newVector.x); Console.WriteLine("Y: " + newVector.y); Console.WriteLine("Z: " + newVector.z);In this example, we create a new MemoryStream and write a Vector3 object to it using the WriteVector3 method. We then rewind the stream and read the Vector3 object using the readVector3 method. Finally, we print out the values of the new Vector3 object. The package library used in this example is KBEngine, which provides networking and game server software tools for game development.
