Map the keyboard arrows to control the car.

Render the inputs that the car is receiving as bars (steering, throttle, braking)

The server now includes a test flag. This test flag should be used to either create a client (or simpler) create a goroutine that will send random input to a Car so that we can start to see some movement around the track.

Convex hull works fine, but it needs some displacement points so that there are both right and left turns.

Also, the number of points used for the convex hull should also be random within a range, to produce more variable shapes.

Right now the outer side of the track is calculated by "expanding" (buffering) the road line polygon.

It would be nice to also get the outer side by "shrinking" it, so that all edges are curved.

The center line of the track could be preserved in another array of points, as it could make calculating the distance easier (way less points in that one, since it doesn't have curves)

Should be fairly easy, including rendering the cars.

• Decouple renderer
• Add option to render Cars

The server should initialise a track when starting up, and set up the comm channels.

Commands from the client

• Init (specifying the number of cars)
• CarControls (sends the controls for all cars)
• Reset (stop the sim)

Data Structures

Car State

CarControlState:
{
  throttle: float // -1.00 <> 1.00, where -1 = brake, +1 = full throttle
  steering: float // -1.00 <> 1.00, where -1 = full left steering, +1 = full right steering
}

CarState:
{
  position: { 
    x: float, 
    y: float 
  },
  velocity: float,
  sensors: [Sensor]
}

Sensor: 
{
  angle: int, // -90 <> +90, degree deviation from straight ahead
  distance: float   // 0.00 <> x, indicating distance to detected object
}
