    # Uses standard 'LeftRight' control for spinning.  'Spin' button for active weapons.
    ### BINDINGS SETTINGS ###
    # 'range' is the range for spinning weapons.
    # 'fbs_range' is the range for full-body spinning.
    # 'PreSpinEntrance' is a time at the beginning of the match the AI won't spin, to get further in the arena.
    # 'right' value of 1 makes the full-body spin direction right/clockwise.  Any other value makes it left/counterclockwise.
    # 'chase_time' is the time interval in seconds with no hits after which the AI will stop spinning temporarily and chase down the opponent.
    ###NOTE:  You must have the correct ID numbers of the bot's weapons in Bindings.py for the chase_time feature to work!!!
