Message API

The message API defines the protocol used to exchange information between the drones and the physics engine. The physics engine sends messages about the position, direction, speed and acceleration to the drones. The drones then know exactly where they are. The drones send control messages to the physics engine, indicating they want to accelerate (or decelerate) or rotate in/to some direction. Other drone components could send control messages, like firing a bullet from a gun.

For milestones 0 and 1 we only need the following messages.

DroneMessage
Position: D3Vector
Direction: D3PoleCoordinate (Absolute direction)
Velocity: D3Vector
Acceleration: D3Vector

ControlMessage
Direction: D3PoleCoordinate (Relative direction change)
Acceleration: D3Vector
