I don’t understand the orientation in the set_cell_item method:

set_cell_item ( int x, int y, int z, int item, int orientation=0 )

The documentation say:

Optionally, the item’s orientation can be passed.

For example: When i use 0 it is original. If i use 10 it is 180 degree rotated. In the source code of the engine there is p.rot used.

Maybe someone can me explain how to calculate the orientation?

It was hiding a bit in the docs but at the end i have found a way (180 degree rotation on y-axis):

 var myQuaternion = Quat(Vector3(0, 1, 0.0), deg2rad(180))
 var cell_item_orientation = Basis(myQuaternion).get_orthogonal_index())
 set_cell_item ( int x, int y, int z, int item, cell_item_orientation )

Code snippet… maybe this helps others. IMHO it should be pointed out in the docs :wink:

There’s an extra brackets in the code.

Check it.
