Table {type = …, under = …, above = …, ref = …}

The utility function minetest.get_pointed_thing_position(pointed_thing, above) can be used to calculate the position of pointed_thing without having to distinguish all possible types.

{type="nothing"}
{type="node", under=pos, above=pos}
{type="object", ref=ObjectRef}

Node coordinates	pointed_thing.above	pointed_thing.under
`(49,6,-13)`	`{x = 49, y = 7, z = -13}`	`{x = 49, y = 6, z = -13}`
`(50,7,-13)`	`{x = 49, y = 7, z = -13}`	`{x = 50, y = 7, z = -13}`
`(49,7,-14)`	`{x = 49, y = 7, z = -13}`	`{x = 49, y = 7, z = -14}`
