It would be fun to learn OTP and messaging. Don't want to waste a lot of time with HTML

Beginner team

For simplicity one team could use LiveView and display the "Barrier". "Crashed". Enter your name. Buttons for Left and right.

Liveview process

Team implements the Live view process that receives messages

Game Engine

Team implements the game engine

  • State is just in a map

Another team checks legality. Can't accelerate past physical capability.

Car Process team

  • Or to make it fun, each car could be a GenServer

  • Receives a update position

  • Returns new position

  • Gets notified when there is a barrier or another car near by

Live view map team

Displays the map each time something changes.

Accelerate

I could setup the project. Create a game process with a set of interfaces

Register car (with pid) Send ticks to each car -- or do they run on a timer? Receive position messages Send barrier alerts and other car alerts.

Setup a framework.

mix new rabbitmq_tutorials
cd rabbitmq_tutorials
Now let's add the dependency on the amqp library. Please modify the applications and deps sections of your mix.exs file to match below:

def application do
  [applications: [:amqp]]
end
defp deps() do
  [
    {:amqp, "~> 1.0"},
  ]
end

How to code. Very quickly with some Kata. Learn some OTP Learn some live view
