Send results

[mrboisvert]

Added a results message type.

Server sends results to each client after the game ends. Each client receives the survival times of each player and a boolean to tell them if they won or lost.

Clients hide the game and show the results after receiving a results message.

I used the player's class names to identify the agents in the results screen. The results don't show a survival time for agent's that lasted the entire game. The results screen also indicates if the game ended in a tie. I can definitely change how the results are displayed if anyone has feedback.

I didn't add any unit tests for this. I think end to end testing is more applicable here. You can submit this code for the first agent to test the results screen:

class MyAgent(Agent):
"""Enter your code here ..."""
x = 20
def run(self):
self.attack_ranged(0)
