##    Instructions:
## Place this script in the script editor below "Materials" and above "Main".
## This allows tagged states to display battle animations on battlers with the
## state applied.  The animation will loop for as long as the state is applied
## and will stop once the state is removed.  The animation will stop while
## another animation is being played unless certain other scripts are used.
##
## state anim id[5]  -etc-
##  - This tag goes into the state's notebox.  As long as the state is applied
##    the animation will play on the battler applied with the state.

                                                                              ##

## The following lines are the actual core code of the script.  While you are
## certainly invited to look, modifying it may result in undesirable results.
## Modify at your own risk!
