Similar to Components, Messages are collections of data.
Messages are used to transmit data between Engines so they can manipulate the game state accordingly.
To define a message, declare a struct which implements the IMessage interface.
using Encompass;
public struct MotionMessage : IMessage {
public Vector2 motion;
}
Messages are temporary and destroyed at the end of the frame.
Because structs are value types, we can create as many of them as we want without worrying about creating pressure on the garbage collector. Neato!
