# ║ Instructions:                                                      ║
# ║   Adjust the settings below                                        ║
# ║                                                                    ║
# ║   Due to the positioning of the enemy,                             ║
# ║   you will likely need to adjust the bar position                  ║
# ║   so that the adjustment numbers are negative.                     ║
# ║   This is because I used the enemies screen position               ║
# ║   which causes the bar to be at the bottom of the                  ║
# ║   enemy position. The window is also set to not                    ║
# ║   overlap the status window.                                       ║
# ║                                                                    ║
