-- ENDERMAN BEHAVIOUR:
-- In this game, endermen attack the player on sight, like other monsters do.
-- However, they have a reduced viewing range to make them less dangerous.
-- This differs from MC, in which endermen only become hostile when provoked,
-- and they are provoked by looking directly at them.
-- TODO: Implement MC behaviour.
