# This scriptlet allows you to manually change both the battleback and

# the battlefloor by using a script call BEFORE battle begins.



# - Change Battleback: Here's an Example:

# $game_temp.battleback = "WhyNotHAL-2000"



# - Change Battlefloor: Here's an Example:

# $game_temp.battlefloor = "YourBattleFloor"
