-- 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
|
