Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Cannot be used as an Xyz Material for an Xyz Summon, except for the Xyz Summon of an Insect-Type monster. Once per turn: You can target 1 face-up Attack Position monster you control; change it to Defense Position, and if you do, Special Summon 1 Level 3 Insect-Type monster from your hand in Defense Position. An Xyz Monster that was Summoned using this card on the field as Xyz Material gains this effect. ● If it is Xyz Summoned: The DEF of all face-up monsters your opponent controls become 0, also change them to Defense Position.
