--MCmobs v0.4
--maikerumine
--made for MC like Survival game
--License for code WTFPL and otherwise stated in readmes
-- ENDERMAN BEHAVIOUR (OLD):
-- 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.
-- Rootyjr
-----------------------------
-- implemented ability to detect when seen / break eye contact and aggressive response
-- implemented teleport to avoid arrows.
-- implemented teleport to avoid rain.
-- implemented teleport to chase.
-- added enderman particles.
-- drew mcl_portal_particle1.png
-- drew mcl_portal_particle2.png
-- drew mcl_portal_particle3.png
-- drew mcl_portal_particle4.png
-- drew mcl_portal_particle5.png
-- added rain damage.
-- fixed the grass_with_dirt issue.
