Hi.

When the rotation parameter of minetest.place_schematic(...) is not "0", what point is the schematic rotated around?

The dev wiki is a bit quiet on the topic:
http://dev.minetest.net/minetest.place_schematic

I've got the rotation working so that the schematic points in the direction the player is facing, but there seems to be a direction dependent offset, even though I'm using the unmodified player position for placing the schematic.
What I mean is that e.g. facing down +X, part of the schematic is placed behind me.
Using "0" for rotation, the position which was pos1 in [World Edit] is placed where I stand.

Schematic rotation is around the vertical axis (+Y) only.

I know that rotation is only about +Y, but around which point of the schematic?

e.g. if I have a schematic which looks like this from above (let X = default:dirt or something):
1XXXXXX
XXX2XXX
XXXXXX3

What would the schematic look like when placed with a rotation of "0", "90", "180", 270"?

The schematic is placed at the pos you set. It places north east. When you rotate the schematic it still places the same direction.
If you have a schematic that is 5 x 10, at 0 rotation it would place 5 nodes north of pos and 10 east.
if you rotate it 90 degrees it would place 10 north and 5 east.

Hope that is clear. It always places north east no matter the rotation.

Ah i see. Yes if you don't have any 'place_center_x/z' flags set it is always North East (+Z +X) of the spawn pos, with the spawn pos at it's SE (-Z -X) corner.

Or use my handle_schematics mod if you want to spawn schematics that always face the player, no matter what direction the player faces.
