5# This file is provided as an example by the PyRat library.
6# It describes a script that creates a PyRat game.
7# Please import necessary elements using the following syntax:
8# from pyrat import <element_name>
9# from players.<player_name> import <player_name>

11"""
12In this script, we visualize four players in the same maze, one after the other.
13Each player is a random player that performs random actions.
14This is useful to see how the players behave in the same environment.
15The maze is the same for all players, thanks to a fixed random seed.
