--- ENDERMAN BEHAVIOUR:
+-- 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.
 -- TODO: Implement MC behaviour.
 
+-- 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.
