Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If a face-up monster you control is changed to face-down Defense Position: You can target 1 card on the field; destroy it. If a Flip monster(s) you control is flipped face-up, even during the Damage Step: You can target 1 of them; inflict damage to your opponent equal to its Level x 200. You can only use each effect of "Sunset Beat" once per turn.
