Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
While this card is in face-up Attack Position on the field, this card is not destroyed as a result of battle. (Damage calculation is applied normally.) A monster that battled with this card cannot change its battle position, except with a card effect, or attack while this card is in face-up Attack Position on the field.
