This script changes the appearance and location of an Entity when a player interacts with it. Even though it is named specifically, this script could be useful in a lot of different cases. The Halloween Fun Example includes a variety of graves that can be emptied and filled by players.
Sounds can be defined for both emptying and filling the grave along with offsets for the positions, rotations and scales of the two objects.
