Attempt to predict the desired orientation of the pillar-like node
|
||
|
|
defined by `itemstack`, and place it accordingly in one of 3 possible
|
||
|
|
orientations (X, Y or Z).
|
||
|
|
|
||
|
|
Stacks are handled normally if the `infinitestacks`
|
||
|
|
field is false or omitted (else, the itemstack is not changed).
|
||
|
|
* `invert_wall`: if `true`, place wall-orientation on the ground and ground-
|
||
|
|
orientation on wall
|
||
|
|
|
||
|
|
This function is a simplified version of minetest.rotate_and_place.
|
||
|
|
The Minetest function is seen as inappropriate because this includes mirror
|
||
|
|
images of possible orientations, causing problems with pillar shadings.
