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

  • type
  • "nothing"
  • "node"
  • "object"

Notes

  • 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.

Examples

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

Node coordinates are (49,6,-13), pointed_thing is {type = "node", above = {x = 49, y = 7, z = -13}, under = {x = 49, y = 6, z = -13}}

pointed thing 2.png

Node coordinates are (50,7,-13), pointed_thing is {type = "node", above = {x = 49, y = 7, z = -13}, under = {x = 50, y = 7, z = -13}}

pointed thing 3.png

Node coordinates are (49,7,-14), pointed_thing is {type = "node", above = {x = 49, y = 7, z = -13}, under = {x = 49, y = 7, z = -14}}
