A simulated player can be used within GameTests to represent how a player moves throughout the world and to support testing of how entities and the environment will react to a player. This type derives much of its structure and methods from the @minecraft/server.Player type. Note that many types of events that may be available for entities more broadly, such as item use events, may not fire in the same capacity for simulated players.
