Anim Precache

#==============================================================================
# ** Theo - Animations Precaching
#------------------------------------------------------------------------------
#  Untuk memproses animasi sebelum masuk game. Seperti loading dalam game.
# Proses precaching dilakukan agar game tidak mengalami banyak lag. Namun
# timpal baliknya adalah game akan memakan memori lebih banyak
