--- Helper function to get the alternate rock type (i.e. urn, mushroom, etc.) that the current room
-- will have.
-- 
-- The rock type is based on the backdrop of the room.
-- 
-- For example, if you change the backdrop of the starting room of the run to `BackdropType.CAVES`,
-- and then spawn `GridEntityType.ROCK_ALT`, it will be a mushroom instead of an urn. Additionally,
-- if it is destroyed, it will generate mushroom-appropriate rewards.
-- 
-- On the other hand, if an urn is spawned first before the backdrop is changed to
-- `BackdropType.CAVES`, the graphic of the urn will not switch to a mushroom. However, when
-- destroyed, the urn will still generate mushroom-appropriate rewards.

--- Helper function to remove all coins, trinkets, and so on that spawned from breaking an urn.
